[A brief analysis] Basic parameters and working principle of LED wall washer

LED wall washer English name Ledwashwalllamp, also known as linear LED flood light, etc., because its shape is long, most of them are aluminum wall washers, also known as LED aluminum strip lights and LED line lights It is mainly used for architectural decoration lighting, and is used to outline the outline of large buildings. Its technical parameters are similar to those of LED floodlights. Compared with the circular structure of LED floodlights, the strips of LED wall washers. The structure of the heat sink appears to be a little better.

First, the basic parameters of high-power LED wall washer

LED wall washers and guardrail tubes have many similarities. Let us introduce the parameters of the LED wall washers on Qin as an example:

1. Voltage:

The voltage of the LED 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 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. However, the wall washer is made of aluminum shell with better heat dissipation, so this general wall washer can meet the requirements.

3.led lamp beads:

The number of LEDs for general wall washers is 9/300mm, 18/600mm, 27/900mm, 36/1000mm, 36/1200mm.

4. Protection level:

This is an important parameter of the wall washer and an important indicator that affects the quality of the current guardrail tube. We have to carry out strict requirements. We use it outdoors, and it is required to have a waterproof rating above IP65. It is 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: flushing with water without any damage.

5. 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. There are also many wall washing systems that directly support the DMX512 control system.

6. Color specifications:

2, 6, 4, 8 full color, colorful, red, yellow, green, blue, purple, white, etc.

7. Luminous angle: The illumination angle is generally narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). Currently, the most powerful LED wall washer (narrow angle) is the most effective. Projection distance is 20-50 meters

8. Mirror surface: glass reflective lens, light transmittance is 98-98%, not easy to atomize, can resist UV radiation

9. Light source
