1, power size:
The power of the wall washer determines the distance to which it is projected. Generally, there are 18W, 24W, 36W, 48W and other parameters. But the power is not fixed. Power can be flexibly changed according to requirements! Generally, high-power led wall washers are single-row, and multi-row is called linear LED floodlights!
2, voltage:
The voltage of the LED wall washer can be divided into DC DC and AC AC. Generally, the built-in power supply is externally connected to AC220V (Japan AC110V), etc., and externally, it is generally low voltage DC24V, DC12V, DC27V and so on. The voltage varies according to different requirements and different manufacturers.
3. IP protection level:
This is an important parameter of the wall washer, and it is also an important indicator affecting the quality of the current guardrail tube. It is required that the waterproof grade should be above IP65, and it is required to have relevant pressure resistance, chipping resistance, high and low temperature resistance, and flame resistance. , impact resistance aging grade.
4, color specifications: divided into colorful, full color, monochrome.
5, color temperature: 2200K or so (amber) 3000K (warm white) 4000K (incandescent lamp) 6000K (white) 7000K (cold white)
6, the angle of illumination:
LED wall washers generally have a narrow angle of illumination (about 20 degrees) (about 50 degrees) wide (about 120 degrees). At present, the farthest effective projection of high-power LED wall washers (narrow angles) in the optical era The distance is 5-10 meters.
7, working temperature:
Because the wall washers are usually used outdoors, this parameter is more important and the temperature requirements are higher. In general, the outdoor temperature we require can work at -40 ° C + 60 ° C.
8, control method:
For LED wall washers, there are currently two control methods: internal control and external control. The internal control means that the external controller is not needed, and the designer designs the control system inside the wall lamp. The degree of effect cannot be changed. The external control is the external controller, and the effect can be changed by adjusting the button of the main control. Usually in large projects, customers can change their own effects. We all use external control.
9, mirror: glass reflective lens, light transmittance of 98-98%, not easy to atomize, can resist UV radiation.
10, light source: generally use 1W, 3WLED as a light source, but due to the immature technology, the current market is 1W is more common, because 3W heat is large, delete heat is not good light decay faster.
