Introduction of LED Wall Washer:

Washing Wall Lamp English Washing Wall Lamp, also known as “linear flood light” or “line lamp”, etc., because its shape is a long strip, most of which are made of aluminum shell, so it is also called “LED aluminum strip light”.

Working principle of wall washer:

Due to the relatively large size and good heat dissipation of the LED wall washer, the difficulty in design is greatly reduced. However, in practical applications, the constant current drive is not very well done, and there are many damages, so How to make the wall washer run better, the focus is on control and driving.

When it comes to high-power LED products, we will mention constant current drive. What is LED constant current drive? No matter the size of the load changes, the circuit that keeps the LED current unchanged is called LED constant current drive. If the wall washer uses a 1W LED, we usually use a 350MA LED constant current drive. The purpose of using the 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 efficiency and stability. I try to choose a constant current source with high efficiency, which can reduce energy loss and temperature.

The LED wall washer is controlled by a built-in microchip. In small engineering applications, it can be used without a controller, and can achieve dynamic effects such as gradient, jump, color flashing, random flashing, and gradient alternation. It can also be controlled by DMX. Realize the effect of chasing, scanning and so on.

Glue requirements for LED wall washer:

  1. Temperature resistance -50~180℃;
  2. High bonding strength to the lamp cover;
  3. Possess routine testing certification and qualifications;
  4. The light bar structure is potted and waterproof, and the adhesive force is strong;
  5. Fill between the heating element and the heat dissipation element, with good sealing, high heat dissipation performance and insulation.
