If for any reason you can not use the stationary electrical network, and there is no portable autonomous lamp in the farm, you can collect the LED flashlight with your own hands.

Led lights

Advantages of LED lamps

LED lighting elements displace the familiar incandescent lamps from the market. This is caused by a number of advantages of LED technologies:

  1. The return of light in semiconductors occurs more intensively. They exceed the light incandescent bulbs 8 times, and also work better than sodium or energy-saving devices.
  2. Due to the high efficiency, the LEDs are capable of saving from 60 to 90% of electricity compared to common light bulbs. LED devices spend less resources than energy saving (15-20%).
  3. The cost of servicing semiconductors is lower, as they have a small amount of failures and failures. LEDs are used in difficult operating conditions - for emergency systems, in high-altitude architectural sites, in designs with an expensive installation, in bridge lighting.
  4. New devices are installed quickly, with considerable savings on cable costs, which in semiconductors need a smaller diameter.
  5. LED devices duration: more than 15 years at work 8 hours per day.
  6. Low voltage is used to power the LEDs. This makes them installation and operation of safer equipment designed for 220/380 V.
  7. Semiconductors have good resistant to vibration, increased mechanical strength, high temperature characteristics.
  8. The color rendition index of semiconductor devices exceeds 80. Without loss of energy and using the device filters, it is capable of ensuring deep and clean lights of light.
  9. LED devices are suitable for timers, volume sensors, dimmers (light power regulators). LEDs are widely used in programmable equipment with a variable lighting intensity.
  10. In diode products there are no ultraviolet and infrared radiation, light monochromatic, no gating and glare. This allows them to apply them in the lighting systems of various purposes, sizes and shapes.
  11. LEDs have a minimum start time. Even with frosty weather, the device instantly gains a color temperature and a given level of illumination.
  12. Due to the lack of harmful emissions and heat, semiconductors can be safely applied for medical purposes, as well as for lighting premises with people, animals and plants.
  13. The devices are processed after the length of the deadline without obtaining hazardous substances.

Rechargeable Lantern Scheme on LEDs

Simple schemes with conventional lamps are energy-proof. They have a weak light stream and lead to a rapid lamp exit. To get rid of these disadvantages, more complex devices with batteries are used instead of batteries and LEDs that replace incandescent bulbs.

LED flashlight diagram on battery

To improve the operating characteristics of the flashlight in its chain include additional items:

  1. Charging is carried out from the network 220 V through the rectifier using the smoothing capacitor C1. The scheme is made so that the part of the electricity is transformed into heat and limited the voltage applied to the battery.
  2. To indicate the charging process, the VD1 LED is turned on.
  3. LEDs are used as a load in the flashlight.

DFL-OSPW5111P super-LED scheme

For the operation of LEDs in such a scheme, 2 AA batteries are used. DFL-OSPW5111R is characterized by high light brightness (30 CD). Required for operation current - 80 mA. The glow of the device is white.

The voltage stabilizer often uses the finished node - the ADP1110 (1111) chip (1111), which refers to the family of switching regulators capable of functioning from supply sources from 2 to 12 V. The device has stationary outputs 12 V, 5.5 V, 3.3 V .

DFL-OSPW5111P super-LED scheme

It is possible to program different microcircuit modes:

  • 200 mA at 5 V, if used 12 in the input and reduction mode;
  • 100 mA at 5 V from 3 in the output and mode of enhancement.

Powered by any types of batteries enters a constant current capacitor relative to high capacity and from its plates to ADP1110. As a source of energy, you can use, for example, "Tablets".

To further filter the voltage and limitations of the pulsations of the current in the diagram, the inductor of inductance and the diode of spacing are used. In the last by the transition of the metal conductor, the barrier effect occurs. The device is characterized by small direct resistance, increased speed and small transition capacity.

Necessary firmware for assembly

To assemble a flashlight with their own hands it will take:

  • Copper wires;
  • Batteries ("Tablets") or battery;
  • LEDs;
  • device for placement of the power supply;
  • soldering iron and solder;
  • knife;
  • glue - liquid nails, epoxy resin, superchalters (it is better to have a gun to accurately apply);
  • switch;
  • Details of the voltage stabilizer depending on the scheme (you can use the recharging micromodule, for example, TP4056; or collect a chain of individual elements yourself);
  • Lantern case;
  • Lenses for the LED.

How to assemble with your own hands?

Collect the LED lamp is easy if there are minimal skills to work with a soldering iron. For example, you can use the old motherboard of the personal computer and drop out of it "Pocket" to fix the battery. This should be done carefully, so as not to damage the surface and contacts.

The case of a small flashlight can be made from the syringe. To do this, you need a paint knife to cut a cone to which the needle is installed and remove the piston.

Corps of syringe

To avoid overheating of the LED, from the aluminum plate you need to cut the radiator in the size of the lens. Using a superclaud, the housing of the lens holder is connected to an aluminum radiator.

Copper wire sucking diode contacts. As an insulation, you can use the thermoembembry and lighter.

The piece with the lens and the LED should be fixed with glue to the body from the syringe.

LED contacts connect with battery contacts and insert into the design.

If the charge of the charging module is not placed in the remaining part of the syringe, it can be divided into two parts and combined with a scotch. Talked contacts should be loosen with copper wire.

Separation of boards for 2 parts

The microswitch via the resistor is required to connect to the charging module board. The remaining contacts of the module are typked in accordance with the scheme.

On the surface after assembling the flashlight, the Micro-USB connector must remain and the switch button. With the right work from one charging, such a flashlight will work 10-12 hours.

Ready flashlight

Refinement of the finished LED lamp

In some cases, it is easier to buy an inexpensive finished flashlight on LEDs and with the help of small improvements to make a more advanced model.

For example, in the HG-528 Huage device and the lanterns similar to it, the EL1-EL5 diodes often fail. The problem arises due to the fact that the owners often forget to disable semiconductor elements when charging from the network.

You can redo your flashlight so that charging will be impossible if you do not change the position of the SA1 switch so to disable LEDs. In addition, short-lived batteries of these devices can be replaced with more energy-intensive lithium-ion devices from mobile phones. For which rectifying diodes VD1-Vd4 and a filter consisting of C1 and two resistors R1, R2 are removed from the lantern.

On the released place are placed after a small drinking of plastic parts of the housing battery from cellular. The latter with copper wire is connected to the instrument diagram.

Using a phone battery

The Lentel GL01 of the LED rechargeable flashlight developers made an error in the electrical circuit, which also leads to the failure of the device, if it is enabled for charging with non-disconnected LEDs. In addition, 7 diodes are included in parallel, which is the cause of the non-uniformity of the current flowing through them during the lantern operation due to the different volt-amps characteristics of semiconductor elements. This leads to a frequent burnout of both the LEDs itself and the R4 resistor.

If individual resistors (45 - 55 ohms) include with each LED sequentially, and the R4 resistor is removed from the chain, then the current values ​​are leveled. To exclude while charging the battery, the voltage to the charged LEDs, you need to connect the HL1 (indicator) to the first SA1 output.

How to repair a LED flashlight?

The most common causes of breakdowns of lanterns, in which LEDs are used as lighting devices, are:

  • LED malfunctions;
  • absence in the supply voltage circuit;
  • breakdown switch;
  • failure of wires that go from the LED to the battery;
  • The contacts to which the batteries are connected, oxidized;
  • Sample or burnout electronic elements of the circuit.

For example, the repair of the LED flashlight handle is often associated with the replacement of the CT315 transistor, which is included in the scheme in series from one of the high-frequency transformer T1 windings. Parallel to the transistor is the VD1 LED, which is the load of the block generator.


The choice of developers of such an element as KT315 is associated with its low cost. Therefore, during the repair of the device, other types of transistors with a frequency of more than 200 MHz can be used instead of the installed conduit device.

If you need to replace the transformer, then you will need a 0.2 mm wire with a diameter.

You need to wind up 20 turns for each winding in the case when a ferromagnetic ring is used. In the absence of the latter, the cylinder is suitable for which the windings will need 100 turns each.

The instrument repair should be started with an external inspection of the lighting and electronic elements of the chain, wires. With the absence of explicit signs of malfunction - burnt parts, torn connections, the presence of plaque and oxides that violate the normal electrical contact, the measurement instruments will be needed, with the help of which the electronic parts can be detected.

Homemade lanterns with their own hands: simple and powerful, overall and mini. Step-by-step instructions, how to make a flashlight from a girlfriend, simple schemes of ultraviolet and LED lamps, all this will be interested in novice self-relocine.

Homemade lanterns with their own hands is a practical and durable thing. Indispensable in everyday life or evening walk.

Using simple schemes, you can make a durable flashlight with high-quality assembly and minimal cost. Dimensions and power chooses the collector himself.

Homemade lanterns

Collect ultraviolet and LED lamp is quite simple. The main thing is to understand how the scheme works, which items are the most necessary. Dimensions, power can be chosen depending on use.

The simplest scheme consists of power and LED, you can add the power button for convenience here. This is a workforce, but for mini lanterns, for example, in a lighter or toy.

If add resistor, lenses, cooler, you can make a simple and powerful flashlight with your own hands. Use it in everyday life at home, light the shed, garage, cellar if necessary or on the street in harsh weather.

Mini flashlight keychain

Very comfortable, portable, bright, can work smoothly for several hours. It will help to open the door in a dark train, will save in any force majeure with a sharp disconnection of light.

Homemade flashlight - excellent interior decoration, which will help create a festive or romantic atmosphere.

Typically, such lanterns are made of paper, but other materials can be used, for example, glass dishes, clothespins, or even ice.

Simple and beautiful paper lanterns

The easiest way to make a flashlight from paper is to roll the tight material into the tube, and decorate with decorative elements. Such work is under the power even to children. Due to the ease of paper, the flashlight will be beautifully squeezed with a small draft.

Paper flashlight can be decorated or enclosed by various decorations. There is a lot of paper lanterns from paper.

Making the simplest paper flashlight can be as follows:

  • Fold a paper sheet twice.
  • From the bending side, perform several cuts. But do not completely cut, leave 1.5-2 cm.
  • Expand the workpiece and fold into the tube. Use glue for fixing.
  • Make a handle in the form of a strip from a separate sheet, and take it to the workpiece.

And photo of finished work homemade can be found on the portal: svoimirykami.guru.

Flying sky lantern

The charm of Chinese lanterns is that they shine brightly and soar in the sky, creating a fabulous atmosphere. Before making a Chinese flashlight, you need to prepare materials for the main structural elements - dome, frame and burner.

Traditionally, in China, the dome is made from rice paper. However, in our area find such material is difficult. Therefore, the easiest solution is to use plastic bags for garbage. It will take 2 packs of 30 liters.

Cut the bottom of one package. Connect 2 packages with glue by making a cylinder. Make out of the wire, you should get a blank in the form of a circle. Its size must correspond to the diameter of the package, which is cut off the bottom. Of the two wires, make a crossover intersecting in the center of the circle.

The burner can be made from foil. Purify the shape of a cup of foil, and attach it to the center of the Crosshair. As a fuel, it is best to use cotton wool or tissue impregnated with alcohol. You can use tablet dry alcohol.

To start the flashlight, first straighten it. Fit fuel in the burner. Do not allow contact with the dome. Place the flashlight on Earth, and just wait until it takes off from hot air accumulation.

Paper Chinese lanterns

Chinese paper lanterns are used to decorate the interior, open areas, solemn events, etc.

Let's make a Chinese lantern from paper with their own hands using the following materials and tools:

  • colored paper;
  • needle and thread;
  • luberers (small rings for working with a cloth);
  • 2 buttons;
  • hole puncher;
  • pencil;
  • scissors;
  • Line.

The flashlight is manufactured in this way:

Cut the paper stripes with a length of 30 cm and 3 cm wide (you can vary, based on the desired dimensions of the future flashlight). One product requires about 14 bands.

Fold the strips into the stack, on the ends, run the holes, and install the recordings. Make an indent of about 1 cm.

To one of the holes, attach an intelligence, grind through it thread. It is necessary to make that the node of the thread is inside the lantern, and the button is outside.

From the chamois, measure the thread on the length corresponding to the size of the lantern (in our case, 15 cm). Make a good node.

Grind thread through the hole on the opposite side. Put on another button and make a node. Use the rest of the thread for the manufacture of a hanging loop.

Distribute the strip in the form of a cylinder, thus collecting a finished flashlight.

If desired, decorate the product with various decor - beads, sequins, coloring, stickers, patterns, beads, etc.

The flashlight may not only have a cylindrical, but also spherical shape. Especially well such products look when hanging under the ceiling.

Flashlight on batteries

You can make a flashlight with a LED bulb on batteries. If there are skills in electronics and soldering, you can make a fully homemade product based on the schemes available in the network.

But for most such an option is complex. Therefore, the easiest solution is to use the finished electronic part from another flashlight. For example, you can disassemble the old lighter with a flashlight.

If you plan to make a flashing flashlight, accordingly you have to search for a work fee with a light bulb that has a flashing function.

Such lights are often found in toys and lighters. You can place the electronic part in the same paper chinese flashlight. For mounting should be installed inside the cross.

In a paper flashlight, it is better to install a crosslinor of light plastic or wooden speakers, because the wire is heavy, and can damage the design.

To fix the LED with a battery inside the flashlight optimally use the thermoclauses. You can use the bulbs of different colors so that the flashlight glows as a rainbow.

Glowing lantern from bank

Another way to make a home flashlight is to use the usual glass jar and a candle. You will also need tracing, PVA glue, brush, ruler, pencil, scissors, colored paper, twine and wire.

Manufacturing instructions:

  • Clean, wash and dry the jar.
  • Cover the jar slightly diluted with glue, then wrap with tracing. Give the workpiece to dry completely.
  • Transfer to the black cardboard the desired drawing (fairy looks very impressive). Cut the applied sketch and stick inside the jar.
  • Decorate the outer side of the cans by any decorative elements. The twine and burlap look very well. But the decor should not overlap the glued pattern.
  • From the colored paper, you can cut petals that glue the neck or the wall of the container by making the flower imitation.
  • Additionally, the bank should be decorated with sparkles that are fixed by PVA glue.
  • Inside place a decorative candle.

After the ignition of the candle in the dark through the glass can be visible a beautiful silhouette of fairies. It looks like really fascinating.

The candle can be replaced by the LED light source. This is a more practical and safe option, moreover, the bank can be tightly closed.

Flashlight from clutches

Very simple, but interesting way, how to make a flashlight with your own hands. Quite attractive externally extinguished.

For the manufacture you will need a glass glass of medium sizes or a low glass, as well as wooden clothespins and glue. Throughout the surface, the capacity needs to be slightly punctured clothespins. Leave small space between clothespins.

Place the clothespins so that the clip is pointing down. If you wish the clothespins, you can decorate in different colors.

But, plastic analogs are better not to use, they can melt and make an unpleasant smell. Inside the cup post a small candle.

On this flashlight is ready, just light the candle and enjoy a pleasant muffled backlight. Such a flashlight can be used as a decorative element.

Photo Tips how to make a flashlight

Simple and original decoration for home interior - paper lanterns. This is a light, available for making manually decorating option. There are also many lantern options from other materials. Consider step-by-step techniques how to make a lantern from paper and other materials. They greatly divert the situation, do not require a lot of strength and time to work.

Features of decorative lamps

Simple and aesthetic lanterns from paper or cardboard a lot of light do not give. But their appointment is different: to make the atmosphere in the room more mysterious or romantic, even without light source inside. This type of decor is very popular, lanterns make their own hands and adults, and children.

Tradition to decorate the house with paper lamps originated in China. For crafts, the Chinese have taken rice paper since ancient times. It was distinguished by transparency, ease and low cost, was easily cut and painted.

With the help of paper scissors, you can realize any ideas, decorate even the exterior of the building for the season. The lanterns look perfectly on the walls, on the ceiling, windowsill, on the New Year tree. Also, they are often made on the school or kindergarten contest.

Materials for work

For the manufacture, almost any healthy material can be useful. The main condition - it should be not heavy, because the lantern is most often suspended. And he must succumb to cutting or be transparent.

Exemplary list of necessary tools and resources:

  • scissors;
  • Medium density paper, but you can take rice, translucent and thin, of any color;
  • paints or pencils, markers for painting;
  • PVA glue or other for gluing jewelry and decor;
  • paper stapler;
  • Tassels for glue and paints;
  • light source (optional);
  • Small ornaments: sequins, sequins, buttons, rhinestones, golden sand.

It is not necessary to buy something to buy, it is quite possible to do the home inventory and infirous materials. Improvisation often gives a more original solution.

Backlight options

How to highlight lights from the inside to be safe? The option with candles is not suitable here. Traditionally, a simple paper flashlight is supplied with such types of illumination:

  • LEDs compact sizes on batteries, without wires;
  • mini candles on diodes with stand;
  • Garlands for the New Year tree, the lantern hangs on each light.


Note! Real candles can be taken only for facing lanterns, while the source of the fire is placed in a glass cup.

Any artificial source is suitable, the main thing is that it is placed inside and does not require constant inclusion manually.

Do lanterns do it yourself

So how to make a flashlight on iPhone when calling? Before you - examples of work and various creative ideas that everyone can implement. The simplest option is a paper tube with slots or patterns inside which the light source is hidden. But you can do without internal illumination. It all depends on the tasks for which the exercise is created.

Classic paper flashlight

The simplest way is to roll a sheet of paper or fine cardboard, glue wide. You can also do figured slits - in the form of flowers, birds, geometric ornament. The main thing is that the slots do not discharged the parts of the product. Optionally, the outer side is slightly missed by glue, sprinkled with golden sand or sequins.

Paper options:

  • lantern-house or castle;
  • basket or lukshko;
  • bell.

Figured lampshades can be cut in any variants depends on the fantasy or paper properties. If there is a house, then you first need to draw or print a template. Any sketches can be taken from the Internet or magazines. Ready souvenir is well decorated with window sills or interior shelves, consoles.

Sugar lamp

An interesting solution is to collect a lantern from Sugara Rafinal. This very unusual design embodiment is easily formed from cubes and is collected in the object of the desired size by analogy with the fortress.

  • First, the cardboard base is made, the layer of cubes is placed on the edge.
  • The center of the lantern put a small candle (for example, floating tea), it will give a pleasant light.
  • The fortress is collected to the top, you can not cover from above (the natural candle will go out from this).

Such a lamp can be placed on the shelf or on the floor, on the porch. Light from it will be soft and pleasant.

Lantern cells

The basis is taken by a cell for birds or small animals - hamsters or mice. You can also make a cardboard pattern-analog. For this purpose, office paper of high density is useful.

As a result, a form for a lantern with contours should be turned out. It is painted as desired, decorated with chains, decorated. It is good to attract to the process of children and the whole family, it diversifies family leisure.

Lamps from boxes and tetrapak

Each house, unnecessary boxes from cardboard are already accumulated in each house - from sweets, toys, technicians, as well as from milk and yogurt. Here it may be necessary to parchment for baking - it additionally strengthens the product from the inside.

  • Pick up a few identical boxes, rinse and dry (if it is washable tetrapak, a box from juice or milk).
  • Cut with a knife or scissors with a lid (it is better to use a pointed dummy knife).
  • Put the box on one side, take the holiday symbols - Christmas trees, stars, snowflakes.
  • Take the walls from the inside by parchment.
  • Place diodes or candles inside the box.
  • Outside, you can paint the lamp in beautiful colors.

From dense boxes, you can make beautiful New Year's garlands and lanterns of any size. Many lanterns on the thread or garland look very elegant. To the lower arc there is also an opportunity to stick or attach colored ribbons, fringe, beads (not news), they will be elegantly waving in the wind or when air moves.

Lanterns from tin

You can also use simple tin cans - from soda, canned food. They are comfortable to decorate the garden or the windowsill, because they will be durable, they are not afraid of moisture and weather conditions.

For the backlight, punch with a hammer and a small nail rows of holes around the perimeter or in the form of a certain pattern, figurines. It may be a lot of stars, a snowman, a bell, a snowflake, a berry, etc. The surface is painted with acrylic paints or glue the application, inside put a candle or light bulb on the battery.

Fragrant lanterns

Very original and effectively from mosquitoes - put the source of light into the peel from orange or lemon. The fruit is taken, the peel is removed in such a way that hemisphere turned out. Half of the hollow "ball" is placed on a heat-resistant stand.

The tea candle is placed inside. It will slowly warm the peel and spread a soft citrus fragrance is very useful for health. Inside, you can put a spice: cardamon, cinnamon, lemgrass, it will turn out to be a real aromatic popurery. In the peel outside the cloves can be stuck.

ATTENTION: Do not allow the peel ignition, it can lead to a fire or an unpleasant odor.

Also, the flashlight can be put on the porch or at the opened window for the aromatization of the room and overclocking insects.

Photo Gallery Flashlight

For exploring examples of works, you can see the photofooting of different models. This is an inexhaustible source of inspiration, which will bring on creative development.

Now you know how to make a flashlight on an iPhone when calling 7. This is a simple and useful entertainment that will help arrange a house for the holiday, work with children.

Photo ideas of unusual lanterns do it yourself

LED light sources today enjoy the greatest success among consumers. Especially popular diode lights. You can get a LED manual flashlight in different ways: you can buy it in the store or do it yourself.

LED hand flashlight

Many people who understand the electronics at least a bit, for various reasons, are increasingly preferred to make such lighting devices with their own hands. Therefore, this article will consider several options for how you can independently make a diode hand flashlight.

Benefits of LED lamps

To date, the LED is considered one of the most profitable effective light sources. It is capable of creating a bright light stream with small capacity, and also has a lot of other positive technical characteristics. Do you have a flashlight from diodes for the following reasons:

  • Separate LEDs are not expensive;
  • All moments of assembly are quite easy to implement with their own hands;
  • Homemade lighting device can operate on batteries (two or one);

Note! Due to the lowest electricity consumption of LEDs during operation, there are many schemes, where only one battery appears as a nutrition of the device. If necessary, it can be replaced with a battery of the corresponding dimensions.

  • Availability of simple schemes for assembly.
Exterior view of LEDs

LEDs and their glow

In addition, the resulting lamp to serve significantly longer than the analogues. In this case, you can choose any color of the glow (white, yellow, green, etc.). Naturally, the most relevant flowers here will be yellow and white. But if you need to make a special backlight of some celebration, you can use the LEDs with more extravagant color of the glow.

Where you can use the features of the lamp

Very often there is a situation when light is needed, but there is no possibility to establish a backlight system and stationary lighting devices. In such a situation, a portable lamp will come to the revenue. LED manual flashlight, which can be done with one or more batteries, will find extensive use in everyday life:

  • It can be used to work in the garden plot;
  • to highlight the chulans and other premises where there is no backlight;
  • Use in the garage when examining the vehicle in the observation pit.

Note! If desired, by analogy with a manual flashlight, a model of the lamp can be easily installed on any surface. In this case, the flashlight will become no longer portable, but a stationary light source.

To make a hand-type LED flashlight need to remember, first of all, about disadvantages of diodes. It impede its disadvantages such as non-linear voltampear characteristic or flux, as well as the presence of a "uncomfortable" voltage for nutrition. In this regard, all LED lamps contain special voltage converters that operate from inductive energy storage devices or transformers. In this regard, before proceeding to an independent assembly of such a lamp with their own hands, you need to choose the necessary scheme. Make sure to make a manual flashlight from the LEDs it is necessary to think about it. You can make such a lamp on batteries (two or one). We will consider several options for how you can make a diode hand flashlight.

DFL-OSPW5111P super-LED scheme

This scheme will assume power from two, not from one, batteries. The assembly scheme of this type of illuminating device is as follows:

An example of a lantern scheme

Lantern assembly scheme

This scheme involves the nutrition of the lamp from the AA batteries. At the same time, a super-light DFL-OSPW51111R LED will be taken as a light source with a white type of glow, having a brightness of 30 kD and current consumption at 80 mA. So, do it yourself a mini-lantern from LEDs on batteries, you need to stock other materials:

  • Two batteries. It will be enough for the usual "tablet", but other types of batteries can be used;
  • "Pocket" for power supply;

Note! The best choice will be "pocket" for the battery made on the old motherboard.

Exterior Superior Diode

Superior diode for a lantern

  • The button with which the homemade lamp will be turned on;
  • glue.

From the tools in this situation will be needed:

  • gun for glue;
  • Solder and soldering iron.

When all materials and tools are assembled, you can proceed to work:

  • First from the old motherboard remove the pocket of the battery. To do this, we need a soldering iron;

Note! Putting the part should be done very carefully, so that in the process do not damage the contacts of the pocket.

  • The button to turn on the flashlight should be soldered to the positive pole pole. Only after that the leg of the LED will be soldered to it;
  • The second leg of the diode must be soldered to a minus pole;
  • As a result, it turns out a simple electrical chain. It will close when the button is pressed, which will lead to the lighting of the light source;
  • After assembling the circuit, we set the battery and check its performance.

If the scheme has been collected correctly, then when you press the LED button, the LED will start glowing. After checking, to increase the strength of the chain, the electrical spikes of the contacts can be pouring hot glue. After that, the chains are placed in the housing (you can use from the old flashlight) and we use on health. The situation of this assembly method is the small dimensions of the lamp, which is easy to fit in the pocket.

Second version of the assembly

Another way to make a LED homemade flashlight - use the old lamp in which the light burned. In this case, you can also power the device with one battery. Here the following scheme will be used for the assembly:

Scheme for Assembling Pocket Lantern

The assembly according to this scheme is as follows:

  • We take a ferrite ring (it can be removed from a luminescent lamp) and wind the wires of the wire 10. The wire must have a cross section of 0.5-0.3 mm;
  • After you wound 10 turns, we make a removal or loop and winds 10 turns again;

  • Next, according to the scheme, connect the transformer, the LED, the battery (one finger will be quite enough) and the CT315 transistor. You can still put the condenser for the brightness of the glow.

Collected scheme

If the diode does not shine, then it is necessary to change the polarity of the battery. If it did not help, then it was not in the battery and you need to check the correctness of connecting the transistor and the light source. Now we complement our scheme remaining details. Now the scheme should have the following form:

Now just left to choose a resistor. It is best to put a variable resistor by 1.5 coma. After that, it is necessary to find the place in which the LED will shine brighter than everything. Next, the assembly of a flashlight with one battery suggests the following actions:

  • Now we disassemble the old lamp;
  • From a narrow single-sided fiberglass, we cut a circle that must correspond to the diameter of the lighting tube tube;

Note! Under the appropriate diameter of the tube it is worth selecting all parts of the electrocups.

Such a flashlight can be powered even from one discharged battery.

Varieties of assembly schemes

In order to assemble the LED flashlight with your own hands, you can use a wide variety of assembly schemes and options. Correctly picking up the diagram can even make a flashing lighting device. In such a situation, use a special flashing LED. Such schemes usually include transistors and several diodes, which are connected to various power sources, including batteries. There are options for assembling a manual diode lamp, when you can do without batteries at all. For example, in such a situation you can use the following scheme:

Scheme option without battery

Here, a stepper motor taken from a floppy disk drive will be used as a power source. It generates a stream of free electrons due to the rotor of pendulum movements.


For self-assembly of the LED flashlight, there are a large number of diverse schemes. We have led only the most popular of them. If you wish, you can even modify the basic scheme, to fit it to your own requests.

The flashlight is the necessary thing when traveling to nature or the city to the cottage. At night on the household site or near the tent only he will create a ray of light in the dark kingdom. But in the urban apartment without it sometimes just can not do. As a rule, it is difficult to get something small and sofa without a flashlight. And although in our time there are devices that are multifunctional and can be the source of light, some of our readers will surely want to learn how to make a flashlight with their own hands. On how to make a small device from the primary items will be described further.

Classic form

The most convenient construction, which, in principle, has remained unchanged for lanterns for many years, is a design containing:

  • cylindrical housing with the same battery form;
  • reflector with a light bulb from one end of the housing;
  • Removable cover from another end of the body.

And this design can be obtained using unnecessary binding items. If you make a flashlight with your own hands, the beauty of the forms like an industrial sample, of course, will not. But it will be functional and from working homemade a lot of positive emotions will be received.

So, the main problem that at first glance is difficult to decide is the reflector. But it only seems difficult. In fact, we are surrounded by many subjects that can become a blank for a variety of reflectors of different sizes. These are ordinary plastic bottles. Their inner surface near the neck in shape is very close to the one that has a reflector made at the factory. And the lid seems to be created for fastening the LED, which today is the best source of light. It is brighter and economical miniature light bulb.

Mastery reflector

What you can not find the tube of suitable sizes for the manufacture of the case is not a problem. It can be glued from individual details. For example, from unnecessary disposable balloons. To spring contacts, you can apply a spiral that is used to interleave pages, and contacts made from a thin sheet of tin, the raw material for which the tin can. Therefore, we begin with the choice of a plastic bottle of the desired size and selecting other elements. The smaller the bottle is, the more hard and strong reflector will turn out. Fastening parts when assembling is easiest to make based on the construction sealant.

So, proceed to the manufacture of a flashlight with your own hands. From the bottle with a sharp knife, cut off the neck and the parabolic part of the case and hang the edges with scissors.

We make a reflector hull We make a reflector hull

For effective reflection, we use foil into which chocolate tiles are wrapped. If its size is not enough, you can cut a larger billet from the foil roll, intended for baking products. So that the foil keeps on the surface, we apply a thin layer of sealant. Then we press and recall the foil on it. If she is wrinkled, it does not matter. The main thing is that there were no bloatings, and she repeated the form of the foundation.

We press with foil with your fingers and, smoothing the irregularities, form the maximum smooth surface. Foil on the edges hanging over the scissors to the floss with a plastic basis. According to the contour, the neck make a cutout with a knife for the LED, which will later be installed in this place on the panel.

It makes it from the bottom of the bottle cover, cutting off a sharp knife edge with a carvings and, if necessary, hanging them with scissors. Then, having done the twil or edge of the knife in the panel, two holes, we produce the legs of the LED, pressing it the base to it. To properly install the LED lamp in the center of the lid, it is necessary correctly by the location of the legs at the base of the LED to select the distance between the holes.

The conclusions of the LED rejects to the side until the edge of the panel is stopped. To them twin fasten the conductors. If a twist turns out unreliable due to the properties of the live wire or for other reasons, a soldering is used. Conclusions after attaching wires are sweeping along the panel. The performance of the obtained part is recommended to check the batteries used in the flashlight.

Then, from the tin sheet, cut the contact pad for the battery, which rests on the panel with the LED. By a twist or soldering, connect the platform - the terminal with a shorter wire. Terminem Krepim to the spring, which in turn is kpripim to the panel. For fastening elements we use sealant.

The opposite of the reflector, the detail of the lantern housing is also made of a piece of a bottle with a neck. But only from the neck itself with the lid. A terminal made from a tin sheet is glued to the inner wall. It also creates the wire. This wire and second wire from the LED will be used to control the flashlight. The terminal is in contact with the battery, being pressed with a lid, which screws into the neck.

Two main details are ready. Now you need to make a battery case. To do this, we use dried and therefore not the necessary markers. We leave only the housing that weochable in length and cut along the axis at the ends along the axis, making two protrusions for gluing. Before cutting, we make a marker mark, applying the felt-meter housing to the glued details.

Insert the batteries into the flashlight and use it. This, of course, is not a lantern of factory manufacture with high-quality reflector and distant light. But it is made with his own hands, it is your own product that gives good neighboring lighting and gives great pleasure, and you can not buy it for money. Now you have received a visual idea of ​​how easily you can make a lantern yourself.

LED light sources Nowadays are so popular that we do not even notice how harmoniously they fit into the objects around us, from simple children's toys and stationery to household appliances. But the ultraviolet and LED lanterns gained particular popularity and deserved glory.

LED-lanterns will not be difficult to find on store shelves, but the quality of their assembly can greatly disappear and, accordingly, such a lighting device will last for a short time.

That is why the masters prefer simple and powerful lanterns to do their own hands. This option will not harm your wallet, as there is no need for expensive parts, and the device will devote to you to serve you for many years.

This article discusses the features of LED light sources, as well as a detailed instruction as a step by step to make a flashlight from handicraft parts with high performance.

Positive qualities of LED lamps

The LED is a very efficient and advantageous source of light, thanks to excellent lighting with small energy costs.

On the Internet you can find quite a few schemes and drawings how to make a flashlight with your own hands, in which only one feed element is needed, and with a special need and it can be changed by a suitable battery.

The LEDs are relatively cheap and have many different bright colors, and the assembly schemes are so simple that they are easily become on the teeth not even especially knowledgeable in the questions of electricians.


To accurately figure out what you can make a flashlight with your own hands, first of all it is worth understanding the minuses of LEDs.

First of all, we are talking about a voltampear characteristic (WA) and a lack of voltage for nutrition. LED light sources are supplied with voltage converters operating from transformers or inductive drives.

Therefore, collecting a flashlight personally, it is especially important to choose and think about the appropriate assembly scheme, as well as its nutrition.

Assembling a bright flashlight on LEDs

It will take for work: a large syringe for 20 milliliters, an LED by 3.4 V / sW, suitable in the size of the lenses, a small button, a resistor with a parameter in 3 ohms / 0.25 W, charging micromodule TR4056, a small light metal plate (preferred aluminum), copper cable, ankb by 3.7 watts, adhesive material, soldering iron and consumables to it, a knife, bormer, adhesive gun and a conventional lighter.


The circle of the plastic cap is circulated on the plate of aluminum. This is necessary to create a radiator, which will protect the LED from heating. By placing the grooves, cut out along the contour. It is best to do it by the borders.

To the rear part of the cap, we stick the future radiator, pre-pulling the lenses. All holes must match.

LED contacts must be accepted and soldered with copper wiring. For safety, paved places to protect Cambridges and warm up a lighter. The resulting LED insert into the cap from the front side.

Housing processing

The handle of the piston of the syringe is not needed and it is better to remove it. A cone for needles also need to be cut off with a knife and adjust the holes for contacts at the corresponding distance. Contacts are placed inward and plastic cap on the adhesive basis.


Lithium battery must be placed inside the future flashlight, after attaching terminals to it. Contacts must be tightly clamped with a battery. For high-quality work, slightly tighten outwards.

In the free place of the lantern case, place two separated parts of the charging module, pre-trusting them and releasing copper.

Final stage assembly

The resistor soldered to the board connects to the button. Propaled contacts protect with heat shrinkable Cammiks.

The remaining three contacts are connected according to the scheme. Lastly connect the pushbutton switch. We all start the remaining place of the flashlight case, leaving at the top USB input and button.

The inner part must be pouring with hot glue with a glue gun. On the front of the flashlight, we set the lenses in the cap, and then put the flashlight for charging.

The flashlight is ready for use and, according to the authors of the scheme, can work for about ten o'clock on one charge.

On the Internet, you can find many photos of the best homemade lanterns and ideas. It contains only the simplest, budgetary, but high-quality scheme that does not cause difficulties even at a novice master.
