Led light strips can not be cut casually.
The number of beads per meter of the led light strip is fixed. For example, the 1210 is 60 lights, the 5050 is 30 lights, and the special is 60 lights. If there are other special requirements, such as 50 lights per meter, this involves modifying the circuit.
How to cut the led light strip
Let's take a look at the LEDs. What is the long line of lights?
Figure: Standard 12V lamp strip, a set of circuit diagrams.
This is the symbol of the light-emitting diode (LED). Each group of light strings is composed of 3 lamp beads + resistors in series. The function of the resistor is to limit the current protection LED. Combined with the working voltage of the LED lamp bead, the working voltage of each group of lamp strings is 12V. .
Figure: Putting a large number of groups in parallel, the voltages of each group can work normally, which is why we can cut the scissors where there is a symbol.
Figure: 12V voltage light bar, generally 3 sets of light beads in each group, the cutting distance is generally 5cm.
Figure: 24V voltage lamp strip, each group of 6 lamp beads, the cutting distance is generally 10cm.
Figure: 220V voltage lamp strip, each group has a variety of lamp beads: 72, 96, 144...
It is the commonly used "Mayi lamp", direct 220V rectification input, which can cut distances up to 1 meter or even 2 meters.
Cutting precautions
a. If it is not 220V light bar, please do not use AC220V to light the light bar directly;
b. Do not reverse the positive and negative poles;
c. The operator should wear an electrostatic ring.
Finally, the description of the connection method of the controller. The LED marquee belt and the RGB full-color strip need to use the controller to achieve the changing effect, and the control distance of each controller is different. In general, the simple controller has a control distance of 10 to 15 meters, and the remote controller The control distance is 15 to 20 meters and the maximum distance can be controlled to 30 meters. If the LED strip has a long connection distance and the controller cannot control that long strip, then a power amplifier is needed for tapping.
In the actual operation, you must pay attention to the connection distance of the LED strip. In general, the 3528 series of LED strips have a connection distance of up to 20 meters, and the 5050 series of LED strips have a maximum connection distance of 15 meters. If this connection distance is exceeded, the LED strip is prone to heat, which will affect the service life of the LED strip during use. Therefore, the installation must be installed in accordance with the requirements of the manufacturer, should not let the LED lights with overload operation.
Led light with precautions
1. When the LED light strip is a roll, please do not illuminate the light strip.
2. Only the scissors mark can be printed on the lamp body, otherwise it will cause a unit to be off.
3. When installing, please bend the lamp to one side to expose 2-3MM copper wire, and cut it with a cutting pliers. Do not leave burrs to avoid short circuit.
4. Do not pass the power supply during the installation or assembly of the lamp strip. Only the connection, the installation and the correct condition can be connected to the power supply.
5, install the LED light strip under cold temperature, you can power on for a few minutes, make the light body soft, easy to bend, and then power off installation.
6. During installation and use, do not hit the lamp with heavy objects and shake the vibration.
7. The end of the lamp tube must be glued with glue before the tail plug is used.
8. Only two lamps with the same specifications and the same voltage can be connected in series. The total length of the serial connection cannot exceed the maximum allowable length.
9, each interface must be firm, no short-circuit hidden dangers, outdoor installation, each interface must be sealed with glass glue or other appropriate methods to ensure that the water at each interface.
10, can not be installed in water, flammable, explosive environment, must ensure that the use of the environment is well ventilated.
11. Install and fix. Do not use metal materials such as iron wire to tightly tie the lamp to prevent the wire from falling into the lamp tube, resulting in short burning of the lamp.
12. The power supply voltage should be marked with the lamp and installed with appropriate safety devices.
