RLED high-power led chip Introduce what is the working principle of the wall washer?
Led high-power lamp cups are used for reflection of high-power LEDs. LED high-power lamp beads are generally used for local illumination, similar to spotlights. LEDs and wall washers are generally used to illuminate walls. . It belongs to landscape lighting. LED underwater lights are usually placed in pools, and are also the kind of landscape lighting. LED underground lights are similar to lawn lights, buried on the ground and used in parks and squares.

The working principle of LED high-power lamp bead wall washer:
The LED wall washer is relatively large in size and better in terms of heat dissipation, so the design is greatly reduced, but in practical use, it will also show that the constant current drive is not very good, and there are many damages. So how to make the wall washer work well, the focus is on the control and drive, the control and drive, the LED constant current device.
When it comes to LED high-power products, we will all mention constant current drive, so what is LED constant current drive? Regardless of the change in the size of the load, the circuit in which the current of the LED remains unchanged is called the LED constant current drive.
If a 1W LED is used in the wall washer, we usually use a 350MA LED constant current drive. The purpose of using the LED constant current drive is to improve the life and light attenuation of the LED. The choice of the constant current source is based on its power and stability. I try to choose a constant current source for work as much as possible, so that energy loss and temperature can be reduced.
