High power consumption, application of LED wall washer
First, the basic definition : wall washers are mainly used for architectural decoration lighting, as well as to outline the outline of large buildings, the technical parameters are similar to LED floodlights, and the heat dissipation device of the strip structure of LED wall washers It seems to be a little better.
Second, the basic parameters : now more LED wall washers are basically selected 1W high-power LED tube (each LED tube will have a high-efficiency lens made of PMMA, its main function is secondary distribution LED tube The emitted light) is arranged in a single line (I classify it as an LED flood light in two or more lines). Most LED wall washers share a single heat sink, and their illumination angle is generally narrow (20 Three degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, the farthest effective projection distance of high-power LED wall washers (narrow angle) is 15-20 meters. 8W, 12W, 24W, 27W, 36W and other power forms, and their common external dimensions are generally 300, 500, 600, 1000, etc., and different lengths and power densities can be selected according to actual engineering applications.
Third, the control form : high-power LED wall washer has two control modes: external control and internal control. The internal control can be equipped with multiple change modes (up to six types) without an external controller, while the external control must be configured with an external control controller. To achieve color change, the current application on the market is also dominated by external control.
Fourth, the main application and achievable effects : LED wall washer through the control of the built-in microchip, in small engineering applications, can be used without controller, can achieve gradient, jump, color flicker, random flicker, gradient Alternate dynamic effects, such as chasing, scanning, etc. can also be achieved through DMX control. At present, the main application sites are all: single-building, historical building group exterior wall lighting; building exterior light, indoor partial lighting; green landscape lighting, billboard lighting; medical, cultural and other special facilities lighting; bars, dance halls, etc. Entertainment atmosphere lighting and so on.
