1. The working principle of LED wall washer

Because the LED wall washer lamp is relatively large in size and better in terms of heat dissipation, it also greatly reduces the difficulty in planning. However, in practical use, it will also appear that the constant current drive is not very good and many of them are damaged. How to make the LED wall washer work better, the focus is on control and driving.


LED constant current


Regarding LED high-power products, we will all mention constant current drive. What is LED constant current drive? Regardless of the size of the load, the circuit that keeps the LED current constant is called LED constant current drive. If a 1W LED is used in the LED wall washer, we usually use a 350MA LED constant current drive. The purpose of using the LED constant current drive is to increase the life of the LED and reduce the light attenuation. The choice of the constant current source is based on its power and stability, as far as possible to choose a constant current source with high power, which can reduce energy loss and temperature.


2. The use of LED wall washer

Let us analyze the application occasions and functions of the LED wall washer. The LED wall washer is controlled by the built-in microchip. In small engineering applications, it can be used without a controller, and can complete mutations, jumps, color flickering, Dynamic effects such as random flashing and mutation replacement can also be controlled by DMX to complete chasing, scanning and other functions.
