Why do low-voltage led wall washers have to use switching power supplies or transformers, and what effects do they have on led wall washers?
The working voltage of the low-voltage wall washer is low. If it is directly connected to AC220V, the excessive voltage will burn the driving power supply and LED light source inside the lamp. Therefore, when using a low-voltage wall washer, it is necessary to use a switching power supply or a transformer to reduce the voltage of the mains, so as to ensure that the lamp can work normally.
However, when there is a problem with the quality of the power supply and the power supply is unstable, the following two situations will occur:
Monochromatic wall washer, when the power supply voltage becomes low, the brightness of the lamp will be visually dimmed; when the voltage rises, the lamp beads will be burned or driven.
In addition to the above two situations, the DMX512 wall washer will also cause the DMX512 signal failure. The intuitive expression is that the lighting effect of the lamp is disordered.
Therefore, when using low-voltage wall washers, the quality of the power supply cannot be ignored. If you want to know more about the application of power supply and led wall washer, you can consult Chongqing Xinyuanhui Photoelectric Technology Co., Ltd. for details.
