Introduction and working principle of LED wall washer

working principle

Due to its large size and good heat dissipation, the design of LED wall washers has greatly reduced the difficulty. However, in practical applications, the constant current drive may not be done well and there may be many damages. Therefore, how to make the wall washer operate better depends on the control and driving aspects. Let's learn about LED constant current devices together. When it comes to high-power LED products, we often mention constant current drive. What is LED constant current drive? No matter the size of the load The circuit where the current of the LED remains constant is called LED constant current drive. If a 1W LED is used in the wall washer, we usually use a 350MA LED constant current driver. The purpose of using LED constant current driver is to improve the lifespan and light decay of the LED. The selection of a constant current source is based on its efficiency and stability. I try to choose a constant current source with high efficiency as much as possible, which can reduce energy loss and temperature.

Application scenarios and effects

The LD wall washer, controlled by a built-in microchip, can be used without a controller in small engineering applications. It can achieve dynamic effects such as gradient, jump, color flicker, random flicker, and gradient alternation. It can also be controlled by DMX to achieve effects such as chasing and scanning. At present, the main application areas are: exterior wall lighting for individual buildings and historical building complexes; Internal and external lighting of the building, as well as local indoor lighting; Greening landscape lighting, billboard lighting; Lighting for specialized facilities such as medical and cultural facilities; Atmosphere lighting in entertainment venues such as bars and dance halls.
