Instructions for making a diode lamp with your own hands. How to make a diode flashlight from a regular LED flashlight homemade

A flashlight is a necessary thing when traveling to nature or out of town to the country. At night, on a personal plot or near a tent, only he will create a ray of light in a dark kingdom. But even in a city apartment, sometimes you just can’t do without it. As a rule, it is difficult to get something small and rolled under a bed or sofa without a flashlight. And although there are devices nowadays that are multifunctional and can be a source of light, some of our readers will surely want to know how to make a flashlight with their own hands. How to make a small device from improvised items will be described later.

Classic form

The most convenient design, which, in principle, has remained unchanged for flashlights for many years, is a design that contains:

• cylindrical body with batteries of the same shape;
• a reflector with a light bulb at one end of the housing;
• removable cover from the other end of the housing.

And this design can be obtained using unnecessary household items. If you make a lantern with your own hands, of course, there will be no beauty of forms like that of an industrial design. But it will be functional and a lot of positive emotions will be received from a working homemade product.

So, the main problem, which at first glance is difficult to solve, is the reflector. But it just seems complicated. In fact, we are surrounded by many objects that can become a blank for a number of reflectors of different sizes. These are ordinary plastic bottles. Their inner surface near the neck is very close in shape to that which has a reflector made at the factory. And the lid is as if created to mount an LED in it, which today is the best light source. It is brighter and more economical than a miniature light bulb.

We make a reflector

It is not a problem that you can not find a tube of suitable dimensions for making a case. It can be glued from individual parts. For example, from unnecessary disposable ballpoint pens. To spring the contacts, you can use a spiral, which is used for page bindings, and make contacts from thin sheet metal, the raw material for which will be a tin can. Therefore, we start by choosing a plastic bottle of the desired size and selecting the remaining elements. The smaller the bottle, the more rigid and strong the reflector will be. Fastening parts during assembly is easiest to do on the basis of building sealant.

So, let's start making a flashlight with our own hands. Cut off the neck and the parabolic part of the body from the bottle with a sharp knife and trim the edges with scissors.

For effective reflection, we use the foil in which chocolate bars are wrapped. If its size is not enough, you can cut a larger blank from a roll of foil intended for baking products. To keep the foil on the surface, apply a thin layer of sealant. Then we press and level the foil over it. If she frowns, it's not a problem. The main thing is that there are no swellings, and she repeats the shape of the base.

We press the foil with our fingers and, smoothing out the bumps, form the most even surface. We trim the foil along the edges with scissors flush with the plastic base. Along the contour of the neck, we make a cutout with a knife for the LED, which will subsequently be installed in this place on the panel.

We make it from the bottom of the bottle cap, cutting off the threaded edges with a sharp knife and, if necessary, trimming them with scissors. Then, having made two holes in the socket with an awl or the tip of a knife, we pass the legs of the LED through them, pressing its base to it. For the correct installation of the LED lamp in the center of the cover, it is necessary to correctly select the distance between the holes according to the location of the legs at the base of the LED.

We bend the LED leads to the sides until they stop against the edges of the panel. We twist the conductors to them. If the twist turns out to be unreliable due to the properties of the wire cores or for other reasons, soldering is used. The conclusions after attaching the wires are bent along the panel. It is recommended to check the performance of the received part with the batteries used in the flashlight.

Then we cut out a contact pad for the battery from the tin sheet, which rests against the socket with the LED. By twisting or soldering we connect the pad - the terminal with a shorter wire. We attach the terminal to the spring, which in turn we attach to the socket. We use sealant to fasten the elements.

Then we glue the socket with the LED into the reflector.

Bottom and battery case

The part of the flashlight housing opposite to the reflector is also made from a part of a bottle with a neck. But only from the very neck with a lid. A terminal made of tin sheet is glued to its inner wall. A wire is also attached to it. This wire and the second wire from the LED will be used to control the flashlight. The terminal contacts the battery, being pressed by a cover that is screwed onto the neck.

The two main parts are ready. Now we need to make a battery case. To do this, we use dried and therefore no longer needed felt-tip pens. We leave only the body from them, which we shorten in length and cut along the ends along the axis, making two protrusions for gluing. Before cutting, make marks with a marker, applying the body of the felt-tip pen to the parts to be glued.

We apply glue to the protrusions and glue them, respectively, to the reflector and the back.

Then we cut out the details of the switch from the tin sheet. We mount the wires to them and glue the parts to the body.

We insert batteries into the flashlight and use it. This, of course, is not a factory-made flashlight with a high-quality reflector and high beam. But on the other hand, it is handmade, it is your own product, which gives good close-range lighting and gives great pleasure, and money cannot buy it. Now you have a visual representation of how easily you can make a lantern yourself.

Ready flashlight and light from it

In this article, we will look at how you can make a powerful LED-based flashlight yourself with your own hands. It will consume much less energy than a regular one.
Today it is quite difficult to buy a quality LED flashlight at a good price. Therefore, we suggest saddling it with your own hands. It is quite easy to make a powerful LED flashlight yourself. The total cost of manufacturing a lantern will be less than what you would pay for a similar factory lantern. It takes a little patience and a great desire, as well as a couple of tools. You can use this device for various purposes: in the garden or in the garden, near the house, to illuminate furniture, as headlights for a car, and even for scuba diving!

To create a DIY LED flashlight, you will need:

• non-working flashlight
• several LED bulbs;
• resistors;
• adhesive - sealant or silicone adhesive of good quality;
• the plate is preferably made of aluminum, but you can take another durable material;
• any reflector.

The main stages of our work:

1. Drawing up an electrical circuit
2. Fabrication and preparation of a plate for LEDs
3. Circuit Assembly
   3.1 Soldering lamp leads
   3.2 Filling contacts and checking them
4. Work with a reflector (preparation and assembly)
5. Fixing all parts of the LED flashlight

So let's get started. The first step is to make a wiring diagram for resistors and LEDs. Lack of knowledge and experience in working with electricity is not a problem. You can complete the scheme by reading the information on Internet sites or through online programs. As a result, following the instructions, you will receive a finished project on the screen.

For the correct modeling and manufacturing of the circuit, it is necessary to clearly determine the voltage strength of the power source and LED lamps, the number of LEDs and the current strength of one LED. All these parameters are indicated in the characteristics and descriptions in the instructions for parts.

The first stage of making an LED flashlight with your own hands is over. We proceed to the next - the manufacture of the plate. This plate will be used as a holder. First, draw on a piece of paper a preliminary diagram of the plate with all the holes for the LEDs. There should be as many holes as there are LEDs. Then cut out the diagram with scissors and glue it to the plate. According to the sketch that is printed on paper, make the corresponding holes in the plate. It will be convenient and easy to do this with a drill.

Next, stretch all the LEDs into the resulting holes. It is important not to hook or damage the contacts. Make sure that cathodes and anodes alternate! All this is desirable to do on a flat surface. As a result, the LEDs should, as it were, “fall through” into the holes. Don't forget to secure the LED bulbs with glue or sealant for added strength and durability.

The third stage of creating a do-it-yourself LED flashlight begins with one more additional layer of glue. Now solder the LEDs and resistors with a regular blowtorch. Take care not to damage or touch the contacts. Remember that before soldering all the tips of the LED bulbs must be shortened. First, mark the positive and negative conclusions so that they are not confused.
Alternatively, you can simply make the negative output a little shorter. It won't affect the quality. Now solder the leads.

Checking and filling contacts is an important step when assembling an LED flashlight. Before proceeding with this task, test the operation of the already received device by connecting it to power. All lamps must be lit. Now we fill in the contacts. It is convenient to do this with ordinary wax or use paraffin. It is best to squeeze out the wax with a syringe so that the contacts do not come into contact with each other. This is a short circuit precaution.

We proceed to work with a reflector. It increases the power of the LED flashlight. Remove the halogen bulb from the reflector. We also recommend cleaning it of the resin on which the lamp was held.
Assembling the LED lamp is the penultimate stage of work on the DIY LED flashlight. To do this, securely fix all contacts. Make sure everything is tight!

Finally, we have come to the end of creating an LED flashlight with our own hands. Molten plastic is needed to fill the contacts. The wax that was used earlier is not suitable, since high reliability and strength are needed here. We solder to a power source, for example, to a regular battery, or to a plug.

After the plastic hardens, cut off the excess leads. Then reconnect the received device to power. If there are no signs of a short circuit within 2 minutes, confidently install the DIY LED flashlight in any place.

At night, one cannot cope without a flashlight - the main electrical device designed for vision. Without this object, a person cannot see anything in the dark at all. The reason for this lies in the fact that a person in the dark is not able to distinguish colors from each other.

Every year more and more photos of homemade flashlights appear on the Internet, which is quite logical, because thanks to such an invented device, you can see absolutely everything in the dark.

Today there are several varieties of flashlights. You can find not only the classic options known to everyone, but also lanterns that provide for self-regulation, if necessary, a beam of light. In this article, we will consider in detail how to make a flashlight with your own hands, using only prepared materials and step-by-step instructions.

Paper lanterns

If you look at various diagrams and instructions on how to make a flashlight yourself, it is easy to see that making it out of paper is easier than from any other material. Moreover, even a child under the supervision of an adult can make a beautiful flashlight out of colored paper.

You can see countless designs on the Internet and looking at them, you can complete them quickly enough. If you want to make a beautiful flashlight, then you can additionally decorate it with such an accessory as paper tape.

A paper lantern is a pretty cute symbol, so even if some homemade lighting assistants don’t shine at all, they are forgiven for their non-functionality.

In addition, they are so beautiful that it is very interesting to make them not only for children, but also for adults. Today, simple and powerful do-it-yourself lanterns are becoming an object that is made even with kids in kindergarten.

How to decorate a flashlight?

A classic paper lantern can be interestingly transformed, for example, with the help of various decor. Ikea is especially successful in this. Every year, more and more different options for using garlands of lanterns on walls and ceilings appear in their magazines. Thanks to such an interesting piece of furniture, you can quickly and budgetarily transform the look of any room.

So, what do you need to make a flashlight at home? Paper, scissors, glue and some decor. Otherwise, there is a real scope for activity, which is not limited by anything.

More holes in flashlights

Today, in various magazines, you can find many different paper lanterns that you can make with a child of any age. You can, for example, try to make a bright pot with holes that will decorate even a classic flashlight model. Most importantly, it will definitely replace a general developmental activity with a child over three years old.

flashlight house

If you want to try making ultraviolet and LED flashlights that are popular today, then you can try choosing the shape of a house for them. Beautiful lanterns in the form of houses or even palaces are quite simple to make. On the Internet you can find a template for almost every taste. If you want to spend more time with your child, you can even try to draw a template for future crafts yourself.

The main thing to consider when creating this type of flashlight is the obligatory creation of grooves. In this case, you will most likely not even get dirty in the glue.

In addition, the thing will become truly unique and no one will meet such a thing anywhere else. You can make such a flashlight in just a couple of hours. The main difference when creating will be only in the material used. Otherwise, they are made in the same way as lanterns in the form of cardboard houses.

When creating such lanterns, keep in mind that the accessory will never be able to become a full-fledged source of lighting. At the same time, the lantern can be used as a night light in the children's room or an additional source of lighting, for example, in the kitchen, provided that the main lighting is bright enough.

More recently, the word LED was associated only with indicator devices. Since they were quite expensive and emitted only a few colors, they also shone faintly. With the development of technology, the price of LED products has gradually decreased, the scope of application has expanded in leaps and bounds.

Today they are used in various devices, they are used almost everywhere where lighting devices are needed. Headlights and lamps in cars are equipped with LEDs, advertising on billboards is highlighted by LED strips. At home, they are also no less often used.

Reasons for using LEDs

Not spared and lanterns. Thanks to powerful LEDs, it became possible to assemble a heavy-duty and at the same time quite autonomous flashlight. Such lanterns can emit very strong and bright light over a long distance or over a large area.

In this article, we will tell you about the main advantages of high power LEDs, and tell you how to fold an LED flashlight with your own hands. If you have already encountered this, then you can supplement your knowledge, for beginners in this area, the article will answer many questions related to LEDs and lanterns with their application.

If you want to save money by using an LED, there are a few things to consider. Since sometimes the price of such a lamp can exceed all the savings. If, on the other hand, you have to spend a lot of money and time maintaining lights, and the total amount of them consumes a lot of electricity, then you should consider whether an LED would be a better replacement.

Compared to conventional lamps, the LED has a number of advantages that elevate it:

• There is no need for maintenance.
• Significant energy savings, sometimes saving up to 10 times.
• High quality light output.
• Very high service life.

Necessary components

If you decide to assemble an LED flashlight with your own hands, for moving in the dark or for working at night, but do not know where to start? You will help you with this. The first thing to do is to find the necessary elements for assembly.

Here is a preliminary list of required parts:

1. Light-emitting diode
2. Winding wire, 20-30 cm.
3. Ferrite ring approximately 1-.1.5 cm in diameter.
4. Transistor.
5. 1000 ohm resistor.

Of course, this list also needs to be supplemented with a battery, but this is an element that can be easily found in any home and does not require special preparation. You should also choose a case or some kind of base on which the entire circuit will be installed. A good case would be an old non-working flashlight or one that you are going to modify.

How to assemble with your own hands

When assembling the circuit, we will need a transformer, but it was not added to the list. We will make it with our own hands from a ferrite ring and wire. It is very simple to do this, we take our ring and start winding the wire forty-five times, this wire will be connected to the LED. We take the next wire, and wind it thirty times already, and send it to the base of the transistor.

The resistor used in the circuit must have a resistance of 2000 ohms, only using such a resistance, the circuit will be able to work without failure. When testing the circuit, replace the resistor R1 with a similar one with adjustable resistance. Turn on the entire circuit and adjust the resistance of this resistor, adjust the voltage to around 25mA.

As a result, you will find out what resistance should be at this point, and you will be able to choose a suitable resistor, with the resistance value you need.

If the circuit is drawn up in full accordance with the above requirements, then the lamp should work immediately. If it doesn't work, then you may have made the following mistake:

• The ends of the winding are connected in reverse.
• The number of turns is not correct.
• If there are less than 15 wound turns, then the current generation in the transformer ceases to be carried out.

Assembling a 12 volt LED flashlight

If the amount of light from the flashlight is not enough, then you can assemble a powerful flashlight powered by a 12 volt battery. Such a flashlight is still portable, but much larger in size.

To assemble the circuit of such a lantern with our own hands, we need the following parts:

1. Plastic pipe, about 5 cm in diameter and PVC glue.
2. Threaded fitting for PVC, two pieces.
3. Threaded plug.
4. Tumbler.
5. Actually the LED lamp itself, designed for 12 volts.
6. Battery for powering the LED, 12 volts.

Insulating tape, heat shrink tubing and small clamps to tidy up the wiring.
The battery can be made by hand, from small batteries that are used in radio-controlled toys. You may need 8-12pcs, depending on their power, so that in total you get 12 volts.

To the contacts on the light bulb, solder two wires, the length of each should exceed the length of the battery by several centimeters. Everyone is carefully isolated. When connecting the lamp and battery, install the toggle switch in such a way that it is located at the opposite end from the LED lamp.

At the ends of the wires coming from the lamp and from the battery pack, which we made with our own hands, we install special connectors for easy connection. We collect the entire circuit and check its performance.

Assembly diagram

If everything works, then proceed to the creation of the case. Having cut off the required length of the pipe, we insert our entire structure into it. Accumulator We carefully fix it inside with glue so that it does not damage the light bulb during operation.

We install a fitting at both ends, fasten it with glue, so we will protect the lantern from accidental moisture getting inside. Next, we bring our toggle switch to the opposite edge from the lamp, and also carefully fix it. The rear fitting must completely cover the switch with its walls, and when the plug is screwed in, prevent moisture from entering there.

To use, just unscrew the cap, turn on the flashlight and tighten it again tightly.

price issue

The most expensive thing you will need is a 12 volt LED lamp. It costs about 4-5 dollars. After digging through old toys of children, batteries from a broken car will be free for you.

A toggle switch and a pipe can also be found in the garage; cuts of such pipes constantly remain after repairs. If there are no pipes and batteries, you can ask friends and neighbors or buy in a store. If you buy absolutely everything, then such a flashlight can cost you about $ 10.

Summarize

LED technology is gaining more and more popularity. Having good characteristics, they can soon completely displace all competitors in the field of lighting. And to assemble a powerful portable flashlight with an LED lamp with your own hands will not be difficult for you.

LED light sources are by far the most popular among consumers. LED lights are especially popular. You can get an LED handheld flashlight in different ways: you can buy it in a store or make it yourself.

LED handheld flashlight

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

Advantages of led lamps

To date, one of the most profitable efficient light sources is the LED. It is able to create a bright luminous flux at low power, and also has a lot of other positive technical characteristics.
Making a flashlight from diodes with your own hands is worth it for the following reasons:

• individual LEDs are not expensive;
• all aspects of the assembly are fairly easy to implement with your own hands;
• homemade lighting fixture can run on batteries (two or one);

Note! Due to the low power consumption of LEDs during operation, there are many schemes where only one battery acts as the power supply for the device. If necessary, it can be replaced with a battery of the appropriate dimensions.

• the presence of simple schemes for assembly.

LEDs and their glow

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

Where can I use and features of the lamp

Very often there is a situation when you need light, but there is no way to install a lighting system and stationary lighting fixtures. In such a situation, a portable lamp will come to the rescue. The LED handheld flashlight, which can be made with one or more batteries, will find extensive use in everyday life:

• it can be used to work in the garden;
• carry out illumination of closets and other premises where there is no illumination;
• use in the garage when inspecting the vehicle in the inspection hole.

Note! If desired, by analogy with a hand-held flashlight, you can make a lamp model that will be easy to install on any surface. In this case, the flashlight will no longer be portable, but a stationary light source.

To make a hand-held LED flashlight with your own hands, you need to remember, first of all, the disadvantages of diodes. Indeed, the widespread use of led-products is hindered by such shortcomings as a non-linear current-voltage characteristic or I-V characteristic, as well as the presence of an “uncomfortable” voltage for power supply. In this regard, all LED lamps contain special voltage converters that operate from inductive energy storage or transformers. In this regard, before proceeding with the self-assembly of such a lamp with your own hands, you need to select the necessary scheme.
If you are going to make a hand-held flashlight from LEDs, it is imperative to think over its power supply. You can make such a lamp on batteries (two or one).
Consider several options for how you can make a diode handheld flashlight.

Scheme with superbright LED DFL-OSPW5111Р

This circuit will assume power from two, and not from one, batteries. The scheme for assembling this type of lighting fixture is as follows:

Flashlight Assembly Diagram

This circuit assumes that the lamp is powered by AA batteries. In this case, an ultra-bright DFL-OSPW5111Р LED with a white type of glow, having a brightness of 30 cd and a current consumption of 80 mA, will be taken as a light source.
To make your own mini-flashlight from battery-powered LEDs, you need to stock up on the following materials:

• two batteries. An ordinary “tablet” will suffice, but other types of batteries can be used;
• "pocket" for the power supply;

Note! The best choice would be a "pocket" for the battery, made on an old motherboard.

• superbright diode;

Superbright diode for flashlight

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

Of the tools in this situation, you will need:

• glue gun;
• solder and soldering iron.

When all the materials and tools are collected, you can get to work:

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

Note! Soldering the part should be done very carefully so as not to damage the contacts of the pocket in the process.

• the button to turn on the flashlight should be soldered to the positive pole of the pocket. Only after that, the leg of the LED will be soldered to it;
• the second leg of the diode must be soldered to the negative pole;
• the result is a simple electrical circuit. It will close when the button is pressed, which will lead to the glow of the light source;
• after assembling the circuit, install the battery and check its performance.

Finished lantern

If the circuit was assembled correctly, then when you press the button, the LED will light up. After checking, to increase the strength of the circuit, the electrical soldering of the contacts can be filled with hot glue. After that, we put the chains in the case (you can use it from an old flashlight) and use it to your health.
The advantage of this assembly method is the small dimensions of the lamp, which can easily fit in your pocket.

Second build option

Another way to make a homemade LED flashlight is to use an old fixture that has a burned out light bulb. In this case, you can also power the device with one battery. Here, the following scheme will be used for assembly:

Scheme for assembling a flashlight

Assembly according to this scheme is as follows:

• we take a ferrite ring (it can be removed from a fluorescent lamp) and wind 10 turns of wire on it. The wire must have a cross section of 0.5-0.3 mm;
• after 10 turns have been wound, we make a branch or a loop and again winds 10 turns;

Wrapped Ferrite Ring

• further, according to the scheme, we connect a transformer, an LED, a battery (one finger battery will be enough) and a KT315 transistor. You can also put a capacitor for the brightness of the glow.

Assembled Circuit

If the diode does not shine, then it is necessary to change the polarity of the battery. If it didn’t help, then it was not the battery and you need to check the correct connection of the transistor and the light source. Now we supplement our scheme with the remaining details. The schema should now look like this:

Scheme with additions

When capacitor C1 and diode VD1 are included in the circuit, the diode will begin to shine much brighter.

Diagram visualizations with additions

Now it only remains to choose a resistor. It is best to put a variable resistor of 1.5 kOhm. After that, you need to find the place where the LED will shine the brightest. Further, assembling a flashlight with one battery involves the following steps:

• now we disassemble the old lamp;
• from a narrow one-sided fiberglass we cut out a circle that should correspond to the diameter of the tube of the lighting device;

Note! Under the appropriate diameter of the tube, it is worth selecting all the details of the electrical circuit.

Fitted parts

• Next, we lay out the fee. After that, cut the foil with a knife and tin the board. To do this, the soldering iron must have a special tip. You can make it yourself by winding a wire 1-1.5 mm wide onto the end of the tool. The end of the wire must be sharpened and tinned. It should look something like this;

Prepared soldering iron tip

• solder the parts to the prepared board. It should look like this:

Finished board

• after that, we connect the soldered board with the original circuit and check its performance.

Schema health check

After checking, you need to solder all the details well. It is especially important to properly solder the LED. It is also worth paying attention to the contacts going to one battery. The result should be the following:

Board with soldered LED

Now it remains only to insert everything into the flashlight. After that, the edges of the board can be varnished.

Ready-made LED flashlight

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

Varieties of assembly schemes

In order to assemble an LED flashlight with your own hands, you can use a wide variety of schemes and assembly options. By choosing the right scheme, you can even make a flashing lighting fixture. In such a situation, a special flashing LED should be used. Such circuits usually include transistors and several diodes that 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:
