How to make a homemade LED lamp

Insufficient amount of light negatively affects the human organs of vision. A homemade LED lamp will be a great helper in lighting your home and eliminate the lack of lighting in the right place. As an element, you can use LED matrices, strips and LEDs taken separately.

The uniqueness of this invention lies in the fact that you can make it from any failed lighting device and arrange it for any interior. You can make a lamp on batteries, this solution will allow you to install the device in a convenient place. The unique lampshade organizes the right direction for the light, will please you and your guests.

A high-tech style lamp can be made from two pieces of board and LED strip in 15 minutes.

Connection diagrams for LED lamps

Do-it-yourself LED lamp is connected to the power supply in two ways. The first method involves using the driver as a power source, and the second - the power supply.

If autonomy and mobility are required, you need a battery-powered lamp. In this case, there must be a battery compartment in the device case. It is better to use a frame from an old non-working electrical appliance, using seats for batteries.

Homemade LED lamp. As an element of light - LED strip. Power source - DC power supply.

Driver

The LED is a non-linear load, its electrical parameters change depending on the operating conditions. Using drivers no need for current limiting resistor, all drivers have a factory value for current strength, according to this indicator, the number of LEDs in the circuit is selected.

Depending on the voltage range in which the driver operates, the number of LEDs that are connected in series is selected, so the connection is made parallel to serial method.

DC power supply.

A feature of the driver is that it always produces the same current from the output filter, regardless of the magnitude and fluctuations of the input voltage. They are made on the basis of transistors or microcircuits.

Power Supply

The power supply has only a rated output voltage, the ignition of the LED is carried out due to the inclusion of a resistor in the circuit, which protects the LED from burning out. When the resistor burns out, the LEDs installed in the module can completely fail.

If you do not want to calculate the circuit with the driver, then it is better to use the power supply and led strip. In this case, attention must be paid to tape power and power supply, creating a margin of 20% in favor of the power supply.

Driver for powering the LED strip.

Drivers are used only to connect LEDs and are the basis of all LED lamps. It is important to note that the driver is designed to work in a specific circuit; it will not work as a power source with other LEDs. Any LEDs can be connected to the power supply, the main thing is that a current resistor is installed in the circuit, and the power consumption of the LEDs does not exceed the peak value of the power supply.

Using Resistor

LEDs have one negative feature - pulsation (regular flicker). To overcome this factor and make the light softer, it is necessary to use an addition in the power supply circuit.

For this, a resistor and a capacitor are used. Luminaires equipped with additional resistance have a softer light, which has a positive effect on the human organs of vision.

Even a novice master can implement this scheme. An additional resistance of 8-12 kOhm is installed in a circuit with LEDs connected in series.

To soften the light, a connection scheme with a linear stabilizer is used.

Electrical part

So, we figured out the power sources, now let's see what we can power. As a light source, you can use an LED strip, any individual LEDs of the required power, and LED matrices.

LED matrix - a set of LEDs on one substrate, the number of which can be completely different. Unlike tape and individual LEDs, the matrix is ​​​​an excellent solution that will satisfy any person. Actively used in spotlights, have different sizes.

Driverless LED Matrix - Do not use in residential areas.

Compact placement significantly reduces board size. Many matrices are based on a plate insulated from the LEDs, which is a heat sink. If the power of the LED matrix is ​​very high, then an additional heat sink is required. It is installed with thermal paste.

Some LED arrays have a built-in driver and are connected by soldering 220 V AC wires directly to the output contacts located on the plate. Such devices are not recommended for use in residential areas due to the high ripple factor. Use driver matrices.

Using a driver LED matrix, you will get the most accurate and compact mounting of LEDs on the board and, accordingly, the look of the lamp will be aesthetic. The amount of light emitted will please you very much, and you can soften its brightness with additional resistance.

The LED driver matrix is ​​a compact solution. Make a DIY LED lamp using this solution, and get the minimum size and directional light.

Depending on the style and design, do not forget about the LED strip, it is possible to use the strip in tandem with the matrix, so you can create special lighting, because the strip has a lot of color shades.

Ideas for creating lamps

The advantage of the idea is that the lamp can be installed permanently, as well as suspended from the ceiling. The creativity of the younger generation is very useful - their masterpieces will become good lampshades, and it is best to use powerful LEDs or a small LED matrix as a light source.

The manufacturing process is absolutely simple, the plastic cover will become the basis for attaching the light element and the lampshade. Fix the light source with a glue gun, the lampshade can be fixed with glue.

To make the lamp become a garland, make holes and assemble the shades on a thread.

To implement the following idea, you will need a wooden beam, three bolts with nuts 40 mm long, a hacksaw, a lamp socket and an electrical cable with a plug. The size of the structure is selected based on your requirements.

The lampshade can be made independently or drag an existing one. It is better to use steel wire as a frame. Use any material for covering, all LED technology emits a fairly small amount of heat, so the risk of fire is minimal.

Fixed structural elements are lubricated with PVA glue and installed in a clamp in a stationary state until completely dry, in a warm place one day will be enough.

The hinged part is carried out strictly according to the markup, otherwise you will ruin the workpiece. Take measurements carefully.

A battery-powered lamp can be made from an old box. To do this, you need to cut holes through which light will enter the premises. It is most convenient to make a cut with a scalpel.

It looks very nice option with stars of different sizes. Choose the color of the lighting individually.

Such a lamp is best used as additional lighting or as a night light.

An aerosol or any used tin can can be used as a base for laying LED strip.This solution is used to compactly lay a large footage in a small area. A strong luminous flux will allow you to install a lampshade that will direct the light to the right place. Arrange at your discretion.

To bring such an idea to life, you will need a base, a tube and an LED strip. All structural elements are assembled absolutely simply. This lamp is used as night light. The battery will be a 12 V DC supply.
