The working principle and application of wall washer
Control form
The high-power LED wall washer has two control methods: external control and internal control. The internal control does not require an external controller and can be built in multiple change modes (up to six), while the external control needs to be equipped with an external control controller to achieve color changes. The LED Linear Wall Washer applications on the market are mostly externally controlled.
Application occasions and effects
The recessed wall wash lighting is controlled by a built-in microchip. In small engineering applications, wall washer kit can be used without a controller. It can achieve dynamic effects such as gradation, jump, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX. Achieve effects such as chasing and scanning.
Main application areas of outdoor wall washer: single building, exterior wall lighting of historical buildings; building interior and exterior light penetration lighting, indoor local lighting; green landscape lighting, billboard lighting; medical, cultural and other special facilities lighting; bars, dance halls and other entertainment venues Atmosphere lighting, etc.
Working Principle
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 led wall washers light work better, the focus is on the control and driver, control and driver, let's learn about the LED constant current device. High-power products related to LEDs will all mention constant current driver, so what is LED constant current driver? Regardless of the size of the load, the circuit that keeps the current of the LED constant is called the LED constant current driver. If a 1W LED is used in the wall washing light fixtures, it is usually a 350MA LED constant current driver. The purpose of using the LED constant current driver is to improve the life and light attenuation of the LED. The choice of a constant current source is based on its efficiency and stability, as far as possible to choose a high-efficiency constant current source, which can reduce energy loss and temperature of the wall wash-lighting.
Application place
The high-power LED wash wall lamp has an irradiation distance of 10-1 meters, which is very suitable for panoramic flood lighting of internal and external walls such as government lighting projects, commercial places, subways, elevated overpasses, building exterior walls, and architectural landmarks. Landscape buildings, outdoor squares. Landscape objects, walls, and exhibits are painted in color. Outdoor LED wall washers can adapt to various indoor and outdoor temperature and humidity environments. The colors are red, yellow, white, green, blue, and colorful.
Through the organic combination of colorful light and water, it produces a smart feeling and brings a dreamlike feeling. The high-power T45 LED wall washer of the Light Age uses 24 high-power LEDs as light-emitting elements, which is a new generation of green lighting products. The long-distance, wide-angle, colorful and colorful throwing effect brings new visual experience to people and immerses people in the unpredictable color world.
