EnglishWash the wall lamp LED constant current device is what?
Followed the development of the high power led technology, the high power led more and more wide use, high power led wash wall lamp is one of use, let us know the details of led wash wall lamp: the above parameters in our choice of high power led wash wall lamp when it is necessary to consider the parameters, for the second time distribution of led tube announced cut light damage, make better illumination, wash wall lamp each led tube will have a high photosynthetic efficiency made of PMMA lens.
Wash the wall lamp manufacturers now wash wall lamp connection by controlling the connector picture let we know more and more short. Led wash wall lamp, because the volume is bigger, better heat dissipation, so also greatly reduced the difficulty in planning, but in practice, also can present constant current drive do not too good, presents the damage of too many, so how to wash the wall lamp can better operation key points on the control and drive control and drive, let's learn the led constant current.
In relation to the led high-power products, we will be filed to the constant current drive, then what is the led constant current drive?
No matter how big or small load. The change, the led current remains unchanged is called the led constant current drive circuit. If wash the wall lamp is punctuated with 1 w leds, we typically 350 ma led constant current drive, with the purpose of the led constant current drive is good in order to improve the led and light failure.
High power led project-light lamp to interval is mainly and lamp power, second, and the lamp bead on the lens Angle, Angle of lens optional for 5-120 degrees, the farther the smaller the Angle - irradiation, planning is smaller, the greater the Angle - according to the closer, the greater the planning.
According to the experience led wash wall lamp manufacturer claims: lights 2 meters, choose 3 w. Lights of 2 to 5 meters, choose 6 w. Lights for 5 to 7 meters, 9 w. Note: 7 lights not monochromatic light irradiation, needs to choose the big level. Constant current source is good or bad choice according to their degree of power and stability, as far as possible choose the constant current source with high power, it can cut down the loss of energy and temperature.
