LED strip is increasingly used in design - luminous colored ribbons adorn niches and arches in apartments, emphasize multi-level structures, fountains, pools, cars.
Incredibly spectacular ribbon, the brightness and color of which can vary due to the controllers, controlled by remote control.
The LED strip is flexibleA board on which are located tiny light sources - light-emitting diodes. The thickness of this tape is only 2-3 mm, and the width usually does not exceed 10 mm. In addition to LEDs, the tape is equipped with resistors - limiting resistors. Most often, glue is applied to the back of the tape, so you can simply glue it to any smooth surface, such as the ceiling or the house's curtain.
Advantages of LED strip
- economy in operation, low power consumption -
- Long service life of light-emitting diodes in comparison with incandescent lamps -
- absence of danger of overheating of elements-
- Wide design possibilities due to the flexibility and small size of the tape-
- the ability to control separately the brightness of each color.
Power Supply Selection
The power supply must comply with the fullLoad of the product, should also take into account the supply voltage, humidity during operation. Most often the supply voltage of the tape is 12 or 24V, sometimes there are specialized products in 36V. At the output of the power supply unit, the voltage that is required for the tape should be specified. When selecting a connector to connect to the power supply, consider the width of the tape - 8 or 10 mm.
When buying a luminous tape should be turnedAttention to a parameter such as power consumption. For example, a power of 4.8 W / meter is indicated. It should be multiplied by the required length of the tape in meters - the total power will be obtained. Suppose, for a 15-meter tape will require a power supply of at least 72 watts. You should add at least 20-30% of the power reserve, otherwise there is a high probability that it will burn at the first power drop. Thus, a 100 W power supply is suitable for this tape.
For use in wet rooms or outdoors, special sealed (waterproof) power supplies and connectors are used.
Mounting the electric circuit of the LED strip
The tape should only be glued afterIt will be connected to the rest of the circuit and verified. It is necessary to solder all connections in advance, connect a dimmer or controller, power supply, then check the operation of the circuit.
You can cut the LED strip only inSpecially marked places, they are marked with strips a few centimeters or marked with painted scissors. For soldering, a soldering iron heated to a temperature of no more than 260 degrees should be used, the time of safe heating is limited to 10 seconds.
For a small LED strip (no more than 5Meters), you can pick up a ready-made connector for connecting and connecting power. Longer tapes require manual soldering, since the connectors can not always provide reliable contact. It is better to connect long strips in parallel, in this case the load on the conductive elements will be lower, and the product will last longer.
The installation of a color RGB tape should be carried out throughRGB controller. The four wires emanating from the tape are indicated by the letters R, G, B (R (red) for the red wire, G (green) for the green wire and B (blue) for the blue wire) and V +, they should be connected to 4 Inputs of the controller with the appropriate designations. Next, the already prepared controller is connected to the power supply.
Adjusting the brightness of monochrome neon strips and modules is done with a dimmer. It is connected in the same way as the controller, between the tape and the power supply.
The power supply has two outputs - "-" and "+". They should be connected to the appropriate wires from the controller, dimmer or LED strip, using a mounting connector or normal twisting. It is important not to make a mistake in the pole, otherwise the tape may burn out.
Next, you need to connect the power supply to the network 220V,Using a two-wire cable. After turning on the power, check the operation of the tape, the operability of the controller. If everything works, you can glue the tape to the surface.
To connect the LED strip in the car power supply is not required, because the output voltage is just 12 V.
Installation of LED strip
When the electrical circuit is assembled and operated,You can begin the installation (pre-disconnecting the controller). Do not crush the tape, bend strongly or subject it to other mechanical forces. It is important not to damage the conductive paths, otherwise the device will not burn or will burn in parts. The maximum bend radius of the tape is 20 mm.
A tape with a power of more than 7.2 W / meter is neededMount on an aluminum or metal profile, to ensure fire safety. If you plan to place the backlight on a metal surface, it should be isolated from it, for example, using special profiles or channels with matt or transparent covers. Placing the tape directly on the metal that conducts the current is dangerous.
The surface should be smooth, smooth, clean,It is better to degrease it in addition. Next, remove the protective coating from the adhesive layer on the back of the tape, attach it to the surface and easily press it. By reconnecting the wires to the controller, dimmer or unit, check the functionality of the design and enjoy the updated design.
