The high-power LED wall washer is relatively large in size and better in terms of heat dissipation, so the difficulty in design is greatly reduced, but in practical applications, it will also appear that the constant current drive is not very good, and the damage is not Therefore, how to make the high-power led wall washer work better, the focus is on the control and drive, control and drive, let’s learn about the led constant current device. High-power products related to LEDs will always mention constant current drive. What is LED constant current drive? Regardless of the size of the load, the circuit that keeps the current of the LED constant is called LED constant current drive. If the wall washer uses a 1W led, usually a 350MA led constant current drive, the purpose of using the led constant current drive is to improve the life and light attenuation of the led. The choice of constant current source is based on its efficiency and stability, as far as possible to choose a high-efficiency constant current source, which can reduce energy loss and temperature.
