Principle Of Washing Wall Lights
Oct 19, 2018

Because the volume of LED wall-washing lamp is bigger and the heat dissipation is better, the difficulty in design is also greatly reduced. But in practical application, the constant-current drive is not very good, and there are many damages. So how to make the wall-washing lamp run better, the emphasis is on control and drive. In terms of system and driver, learn the LED constant current. The high-power products related to LED will mention constant current drive. What is LED constant current drive? Regardless of the size of the load, the current of the LED remains constant. 

The circuit is called LED constant current drive. If you use a 1W LED inside a wall-washing lamp, usually 350MA LED constant-current drive, the purpose of using LED constant-current drive is to improve the life and light fading of the led. The choice of constant current source is based on its efficiency and stability, as far as possible to choose high efficiency constant current source, which can reduce energy loss and temperature.
