Analysis of technical principle of LED high power wall washer
The basic parameters of high-power LED high-power wall washers LED high-power wall washers and guardrail tubes have many similarities. Let us introduce the parameters of Qin high-power LED wall washers as an example:
Voltage
The voltage of the LED high-power wall washer can be subdivided into 220V, 110V, 36V, 24V, 12V, and so on, so we pay attention to the corresponding voltage when selecting the power supply.
2. Working temperature
Because high-power 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. However, the high-power wall washer is made of aluminum shell with better heat dissipation, so this high-power wall washer can meet the requirements.

3. LED lamp beads
The number of LEDs for general high-power wall washers is 9/300mm, 18/600mm, 27/900mm, 36/1000mm, 36/1200mm.
4. Protection level
This is an important parameter of high-power wall washers and an important indicator that affects the quality of the current guardrail tubes. We have to carry out strict requirements. We use them outdoors, and it is best to require waterproof grades above IP65. Also required to have relevant pressure resistance, chipping resistance, high and low temperature resistance, flame resistance, impact aging grade IP65, 6 means complete prevention of dust entry; 5 means: rinse with water without any damage.

5. Control method
For LED high-power 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, and the degree 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 use external control. There are also many wall washing systems that directly support the DMX512 control system.
