How to make a homemade LED light fixture

The lack of light negatively affects the human visual organs. A homemade LED light will be a great helper to illuminate your home and eliminate the lack of light in the right place. As an element you can use LED matrixes, strips and taken separately LEDs.

The uniqueness of this invention is that you can make it out of any broken-down lighting fixture and decorate it for any interior. You can make a lamp on batteries, this solution will install the device in a convenient location. Unique lampshade will organize the right direction for the light, will please you and your guests.

Lamp in the style of High-Tech can be made from two scraps of board and LED strip in 15 minutes.

Wiring Diagrams for LED lights

LED lamp with their own hands is connected to the power supply in two ways. The first way involves the use of a driver as a power source, and the second - the power supply.

If you want autonomy and mobility, you need a battery-powered lamp. In that case, there should be a battery compartment in the body of the device. It is better to use a frame from an old non-working electrical appliance, using the battery slots.

Homemade LED light fixture. The light element is an LED strip. Our DC power supply is a power adapter.

The driver

The LED is a non-linear load, its electrical parameters vary depending on the operating conditions. When using a driver is not required to use a current-limiting resistorAll drivers have a factory default value for the current strength, this value is used to select the number of LEDs in the circuit.

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 in parallel in series method.

Constant voltage power supply.

A special feature of the driver is that it always outputs 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 the calculated voltage at the output, the LED lights up due to the inclusion of a resistor that protects the LED from burning out. When the resistor burns out, the LEDs installed in the module can fail completely.

If you don't want to calculate a circuit with a driver, it is better to use a power supply and LED strip. In that case, you need to pay attention to strip power and the power supply, creating a margin of 20% in favor of the power supply.

Driver to power the LED strip.

Drivers are only used to connect LEDs and are the basis for all LED lights. 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. To the power supply you can connect any LEDs, most importantly that the circuit was installed current resistor, and the power consumption of LEDs does not exceed the peak power of the power supply.

The use of resistor resistance

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

For this purpose, a resistor and a capacitor are used. Fixtures equipped with additional resistance, have a softer light, it is beneficial for the human visual organs.

Even a beginner can implement this scheme. An additional 8-12 kΩ resistor is installed in the circuit with the LEDs in series.

To soften the light, a wiring diagram with a linear stabilizer is used.

Electrical part

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

LED matrix - a set of LEDs on a single substrate, the number of which can be completely different. In contrast to the tape and LEDs taken separately, the matrix is an excellent solution that will satisfy anyone. Actively used in spotlightsHave a variety of sizes.

Driverless LED matrix - do not use in residential areas.

Compact placement significantly reduces the size of the board. 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, it is required to install an additional heat sink. It is installed on thermal paste.

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

By using a driver LED matrix, you get the most accurate and compact mounting of LEDs on the board and, accordingly, the appearance of the lamp will be aesthetically pleasing. The amount of light emitted you will be very pleased, and its brightness you can soften the additional resistance.

The LED driver array is a compact solution. Make a LED light fixture with your own hands using this solution, and get a minimum size and directional light.

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

Ideas for creating lighting fixtures

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

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

To make the light fixture into a garland, make holes and assemble the lamps on a string.

For the following idea, you will need a wooden bar, three bolts with nuts 40 mm long, a metal hacksaw, a lamp socket and an electric cable with plug. The size of the construction is chosen based on your requirements.

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

Fixed elements of the structure are smeared with PVA glue and installed in the clamp in a stationary state until it dries completely, in a warm place will be enough for one day.

Hinged part is made strictly on the markings, otherwise you will ruin the workpiece. Take measurements carefully.

Recommended for viewing.

You can make a battery-operated light from an old box. To do this, you will need to cut holes through which the light will enter the room. The most convenient way to make a cut is with a scalpel.

It is very beautiful to look variant with stars of different sizes. Choose the color of the light individually.

It is better to use such a light as additional lighting or as a night light.

Aerosol or any waste tin can be used as a base for laying the LED strip. This solution is used to compactly lay a large meter in a small area. Strong light output will allow you to install a lamp shade, which will direct the light to the desired location. Design at your discretion.

To bring such an idea to life will require a base, a tube and an LED strip. All elements of the design are assembled absolutely easy. Such a lamp is used as a nightlight. The power element will be a 12 V DC power supply.
