The Principle Of Wall Washer

- Nov 25, 2018-

LED wall washers are relatively large in size and heat dissipation, so the design is also greatly reduced in difficulty. However, in practical applications, constant current driving will not be done too well, and there are many damages. So how to make the wall washer work better, focus on control and drive, control and drive, and learn about LED current regulator. High-power products related to LEDs will be lifted to constant current drive.


What is LED constant current drive? Regardless of the change in load size, the circuit in which the LED current remains unchanged is called LED constant current drive. If the wall washer is used as a 1W LED, usually 350MA LED constant current drive, the purpose of LED constant current drive is to improve the life and light decay of the LED. The choice of constant current source is based on its efficiency and stability, and choose a high-efficiency constant current source as much as possible, which can reduce energy loss and temperature.
