1. Power size:
The power of the wall washing lamp determines its projection distance. Generally, the parameters are 18W, 24W, 36W and 48W. But the power is not fixed. Power can be flexibly changed according to requirements! General high-power LED wall washing lamp refers to a single row, multi row that is called linear LED projector!
2. Voltage:
The voltage of LED wall washing lamp can be divided into DC and ac. generally, the built-in power supply is externally connected with AC220V (AC110V in Japan), and the external power supply is generally low voltage DC24V, DC12V, dc27v, etc. Different manufacturers have different requirements and voltages.
3. IP protection level:
This is an important parameter of the wall washing lamp, and it is also an important index that affects the quality of the current guardrail tube. It is good to require that the waterproof grade should be above IP65, and that there should also be relevant pressure resistance, fragmentation resistance, high and low temperature resistance, fire resistance and impact aging resistance.
4. Color specification:
Divided into seven colors, full color, monochrome.
5. Color temperature:
2200k (Amber) 3000K (warm white) 4000K (incandescent lamp) 6000K (positive white) 7000K (cold white)
6. Luminous angle:
Generally speaking, there are three kinds of LED wall washing lamps: narrow (about 20 degrees), medium (about 50 degrees) and wide (about 120 degrees). At present, the far effective projection distance of high-power LED wall washing lamps (narrow angle) in the light age is 5-10 meters.
7. Operating temperature:
Because the wall washing lamp is usually used outdoors, so this parameter is more important, and the temperature requirement is relatively high. Generally, the outdoor temperature we require can work at - 40 ℃ and + 60 ℃.
8. Control mode:
At present, there are two control methods for LED wall washing lamp: internal control and external control. Internal control means that there is no external controller. Designers design the control system in the wall lamp, and the degree effect can not be changed. External control is external controller, its effect can be changed by adjusting the main control button. Usually, in large-scale projects, customers require that they can change the effect by themselves. We all use the external control scheme.
9. Mirror surface:
Glass reflective lens, light transmittance of 98-98%, not easy to atomize, can resist UV radiation.
10. Light source:
Generally, 1W and 3W LED are used as the light source, but due to the immature technology, 1W is commonly used in the market at present, because 3W has a large calorific value, the heat removal is not good, and the light decay is relatively fast.
