LED strip is a modern, versatile light source that can be used for decorative purposes inside and outside rooms. Multi-tiered ceiling structures, interior arches and niches, furniture, cars, billboards - this is a small list of places that transforms this kind of lighting. Compact and flexible lighting fixture can be placed in hard-to-reach places, long term use allows you to not worry about frequent replacement. In this article we will look at how to do the installation of LED tape do it yourself.
Waterproof LED strip
Lighting strips are made of strip a dielectric material on which diodes emitting light are fixed at equal intervals. On the basis of a tape special paths along which electric current passes are put. To limit the strength of the current in the circuit include resistors. The width of the lighting device varies from 8 to 20 mm, thickness is only 3 mm. The degree of illumination depends on the number of LEDs on a meter of a tape, it may differ tenfold - 30-240 pieces. The size of each diode is indicated in the ribbon marking, the larger it is, the more intense its luminous flux. In powerful devices, the light sources are arranged in several rows. The length of the standard strip is 5 meters, it goes on sale on reels. The cutting points are marked on the substrate, the tape can be divided only along these lines.
Splitting the LED tape
The main classification of LED strips is by color, emitted glow:
Lighting devices are issued open, intended for internal installation, and moisture-proof, calculated for use in the street and in water, a class of protection - IP. For ease of mounting, some LED strips are equipped with self-adhesive film.
Stretch ceiling LED lights
The main disadvantage of LED lighting is its high cost, to create a full-fledged basic lighting will require large expenditures. This has caused the use of tapes as an additional or decorative ceiling lighting.
For LED operation The tape needs a DC source, so connection to the common network is excluded. You must install a device that converts alternating current into direct current, with a voltage of 12 or 24 volts. To choose the right power supply, you need to calculate its power. For the calculation, the power value of 1 meter of the tape, the total footage of the light fixture used and the safety factor are taken. For example, SMD 3014 with a length of 6 meters - 24 * 6 * 1.15 = 165.6 W - the power value for the power supply. The operating voltage of the tape is indicated by the manufacturer.
When using multiple tapes, it is possible to make a common power supply, but due to high power, such a device will have considerable dimensions and there will be difficulty with its hidden placement. It is more convenient for each lighting strip to pick up a separate power source. Thinking how to connect the LED strip to the power supply, choose a parallel circuit. If you connect the tape in series, the remote diodes will receive less than all the voltage and will be dull.
Controller for LED strip
Connecting an RGB ribbon requires the inclusion of a controller in the circuit. If you connect directly to the power supply, the tape will glow, but the color will not change.For connection there are four wires, and on the controller, the terminals with the color designation:
For the fourth wire, the terminal is indicated by a voltage number of 12 or 24 V. After connecting to the LED strip, the controller is connected to the power supply.
LED strip can only consist of LEDs of the same color. In this case, the controller is not required to connect it.
Connection scheme for several LED strips
Operation It begins with the cutting of strips of the desired length, it is necessary to ensure that the incision passes along special marks. The connection sections of the tape can be carried out in two ways: using special LED connectors or soldering. Assembling the circuit using connectors can be quite quickly and simply enough to put the tape on the contact pad and close the lid. This mechanical method does not require any skills, but the cost of the part is quite high, if several connections are required, this will significantly increase the cost of lighting.
Low Power Supply
The simplest power supply has two terminals, one of which plus the other - a minus, when connecting to the controller, it is important not to confuse them, otherwise the device will fail. After collecting the entire circuit, it is connected to the network through the input of the power supply. If the LED strip is functioning properly, it can be fixed in the chosen place.
If it is necessary to splice the ends of the tape without a connector, a low power soldering iron is used. A layer of solder is applied to the contact pads of the joining tracks, and a protective film must be removed from the tape base. Further, the two parts overlap one another and are heated by a soldering iron until the solder is melted.
Do not make the length of the LED strip more than five meters, because the LEDs on the end of the strip will not shine at full power.
Amplifier for LED strips
If you need to connect several color strips, an amplifier is installed. This device is placed behind the first LED strip, and the second is connected to it. This scheme uses one controller and two power supplies. Single-color LED strip has only two wires to connect to the power supply: red means plus and blue means minus.
LED tape soldering
The connection is made mechanically or by soldering. To do this, the ends of the wires are stripped of insulation and tinned. A layer of solder is also applied to the contact parts of the tape. Attaching the wires to the pins, they are alternately touched with a soldering iron. Despite the low voltage, bare ends should be wrapped with insulating tape. A dimmer can be installed in the circuit between the ribbon and the power supply to regulate the luminous flux.
Installation of the LED ceiling lighting is made on a clean and degreased surface. Only by observing this condition, ensure reliable fixing of the illuminant.
The latest models of LED strips are offered with the complete set of everything you need to connect - a power supply unit that has protection against incorrect polarity connections, and a controller.
