LED lights with a general voltage of 12V DC, so the need to use the switching power supply, the size of the power according to the LED lights with the power and connection length to set. Monochrome 5050 SMD LED lights with the wiring is to distinguish between positive and negative, we generally provide a good power plug welding, plug directly into the lamp with our power supply above, if you do not want every LED lights are used A power to control, you can buy a relatively large power of the switching power supply to do the total power, and then all the LED lights with all the input power in parallel, unified by the total switching power supply.
LED lights with installation Note: the controller connection
LED Marquee and RGB Symphony lights need to use the controller to achieve the effect of change, when the wiring. Symphony of light are generally a total of the anode, that is, there is a light above the band is +12 V other are negative RGB three negative, wiring and control of each controller is not the same distance, in general, simple control Control distance of 10 to 15 meters, remote control controller control distance of 15 to 20 meters, the longest can be controlled to 30 meters distance.
LED lights with installation Note: Note that the connection distance LED lights
In general, LED lights with its connection distance of up to 20 meters, if beyond the connection distance, the LED light belt is very easy to heat, the use of the process will affect the LED lamp with the service life. Therefore, the installation must be in accordance with the requirements of manufacturers to install, should not let LED lights with overload operation.
