XYH solves your puzzles about the working principle of wall washer leds

Aug 29, 2022

In recent years, LED wall washers have been widely used in various places, such as the wall lighting of company buildings, government buildings, historical buildings, entertainment venues, etc.; the planning involved is also more and more more and more.

The working principle of LED wall washer

Because the LED wall washer is relatively large in size and better in heat dissipation, the difficulty in planning is greatly reduced, but in practical application, the constant current drive is not very well done, and there are many damages. So how to make the wall washer work better, the focus is on control and driving, let us learn together.

1. LED constant current device

When it comes to high-power LED products, we will always mention constant current drive. What is LED constant current drive? Regardless of the change of the load, the circuit in which the LED current remains unchanged is called LED constant current drive. If a 1W LED is used in the wall washer, we usually use a 350MA LED constant current drive. The purpose of using LED constant current drive is to improve the life and light decay of the LED. The choice of the constant current source is based on its power and stability. I try to choose a constant current source with high power, which can reduce energy loss and temperature.

2. Application of led wall washer

Let's analyze the main applications and functions of the wall washer. The LED wall washer is controlled by a built-in microchip. In small-scale engineering applications, it can be used without a controller, and can achieve sudden changes, jumps, and colors. Dynamic functions such as flickering, random flickering, and mutation replacement can also be controlled by DMX to complete the functions of chasing and scanning.

3. Application place

Application place: single building, exterior wall lighting of historical buildings. The building has internal and external lighting, and indoor local lighting. Green scene lighting.
