1. Definition: LED wall washer is also called linear LED flood light, etc., because its shape is long, some people call it LED linear light, which is mainly used for architectural decoration lighting, and it is also useful To outline the outline of a large building, its technical parameters are roughly similar to those of LED floodlights. Compared with the circular structure of LED floodlights, the strip-shaped heat sink of LED wall washers is a bit easier to handle.
2. Parameters: The most widely used LED wall washers are basically 1W high-power LED tubes (each LED tube will have a high-efficiency lens made of PMMA, and its main function is to distribute the LED tube twice.), in a single-line arrangement (two-line or multi-line arrangement I will classify it as LED flood light), most of the LED wall washer LED tubes share a radiator, and some manufacturers install each LED tube A small radiator generally has three types of light-emitting angles: narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, high-power LED wall washer (narrow angle) is the farthest effective The projection distance is 15-20 meters, and its common power is about 8W, 12W, 24W, 27W, 36W and other power forms, and their common dimensions are generally 300, 500, 600, 1000, etc., which can be based on actual conditions. Choose different lengths and power densities for engineering applications.
3. Control form: The high-power LED wall washer has two control modes: external control and internal control. The internal control does not require an external controller and can be built in a variety of change modes (up to six), and the external control needs to be equipped with an external control controller The color change can only be realized, and most of the applications currently on the market are externally controlled.
4. Main application occasions and achievable effects: LED wall washer is controlled by built-in microchip. In small engineering applications, it can be used without a controller, and it can achieve gradual change, jump, color flashing, random flashing, and gradual change. Dynamic effects such as alternation can also be controlled by DMX to achieve effects such as chasing and scanning. At present, the main application areas are: single buildings, exterior wall lighting of historical buildings. In the building, the light is transmitted from the outside and the indoor local lighting. Greening landscape lighting, billboard lighting. Lighting for specialized facilities such as medical treatment and culture. Atmosphere lighting in entertainment venues such as bars, dance halls, etc.
