The most widely used LED wall washer is basically a 1W high-power LED tube (each LED tube will have a high-efficiency lens made of PMMA, and its main function is to secondarily distribute the light emitted by the LED tube). Single-line arrangement (two-line or multi-line arrangement, I classify it as LED flood light), most of the LED wall washer LED tubes share a radiator, and their light-emitting angles are generally narrow (about 20 degrees), medium ( About 50 degrees), wide (about 120 degrees), the farthest effective projection distance of high-power LED wall washer (narrow angle) is 5-20 meters, and its common power is about 9W, 12W, 18W, 24W, There are several power forms such as 36W, and their common dimensions are generally 300, 500, 600, 900, 1000, 1200, 1500mm, etc., and different lengths and power densities can be selected according to actual engineering applications. Projection distance: According to the lens 5-20 meters, the smaller the angle, the farther the projection distance. Beam angle: 6-90 degree floodlight Mirror: glass reflective lens, light transmittance is 98-98%, not easy to fog, can resist UV radiation The lamp body is made of pure aluminum, and there are a variety of optional shapes, such as square, long, and optional lengths: 300, 500, 600, 1000, 1200, 1500mm. Width and height are fixed (1 meter is a regular product) Protection level: IP65—IP67 (the highest IP68) structured waterproof wall washer can reach I67 effect, with high waterproof and long-term characteristics. Even long-term use will not affect its waterproof performance! ! There are also many types of wall washer shapes, which are long, round, square, length, and size, which can be selected by themselves. They are suitable for building installation and use of different shapes. The control method is also controlled by the original master-slave connection, and now it supports offline or built-in control. The installation method also supports wireless DMX control. The light effect channel of the lamp beads is also upgraded from the original conventional 3 channels to 4 to 20 channels. Each group of lamp beads can be freely configured with luminous effects to achieve different color shaping effects and create completely different visual effects for large buildings! Power supply specifications: DC and AC can be divided into, generally the built-in power supply is connected to AC220V (Japan AC110V) city power, etc., and the external power supply is generally low-voltage DC24V, DC12V, DC27V, etc. The voltage is also different according to different requirements. Color specifications: full color, colorful color, red, yellow, green, blue, purple, white and other colors. Development trend: The wall washer is mainly developed towards the ultra-thin aspect, because the ultra-thin wall washer will relatively reduce the transportation cost and is more convenient when working at heights.
