Talking about the working principle of LED wall washer
The LED wall washer is relatively large in size and better in terms of heat dissipation, so the difficulty in design is greatly reduced, but in practical applications, it will also appear that the constant current drive is not very good, and there are many damages. So how to make the wall washer work better, the focus is on the control and drive aspects, let us learn together.
1. LED constant current device
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 current of the LED 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 drive. The purpose of using the LED constant current drive is to improve the life and light attenuation of the LED. The choice of constant current source is based on its efficiency and stability. I try my best to choose a constant current source with high efficiency, which can reduce energy loss and temperature.
2. The application of led wall washer
Let us analyze the main applications and achievable effects of the wall washer. 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 gradation, jump, and color. Dynamic effects such as blinking, random blinking, and gradual alternation can also be controlled by DMX to achieve chasing, scanning and other effects.
3. Application place
Application places: single building, exterior wall lighting of historical buildings. Inside the building, the light is transmitted through the outside lighting, and the indoor local lighting. Greening landscape lighting
LED wall washer and billboard lighting. Lighting for specialized facilities such as medical treatment and culture. Atmosphere lighting in entertainment venues such as bars, dance halls, etc.
4. The trend of LED wall washer
In recent years, LED wall washer has been widely used in various places, such as the wall lighting of company and corporate buildings, the lighting of government buildings, the wall lighting of historical buildings, entertainment venues, etc.; the range involved is also increasing The wider, from the original indoor to the outdoor, from the original partial lighting to the current overall lighting, is the level of improvement and development. With the increasing progress of the times, Qinshang LED wall washers have now been invested in various fields. Among the lighting projects, LED wall washer will develop into an indispensable part of the lighting project in the next few years.
