The power of the LED wall washer determines the distance of its projection. Generally, there are 18W, 24W, 36W, 48W and other parameters. But the power is not fixed.

    The power can be flexibly changed according to the requirements. Generally, the high-power LED wall washer refers to a single row, and the multi-row is called a linear LED flood light. For other problems due to heat dissipation, it is best not to use a single 1W wall washer for a 1-meter wall washer beyond 36W, otherwise poor heat dissipation will cause serious light decay.

     The LED wall washer allows the light to wash the wall like water. It is mainly used for architectural decoration lighting, and it is also used to outline the generalization of large buildings. Because LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, in 2013, the wall washer of other light sources was gradually replaced by LED wall washer

     Whether the LED lamp is stable or not, the quality of the lamp is very important to the heat dissipation of the lamp body itself. At present, the heat dissipation of high-brightness LED lamps on the market usually adopts natural heat dissipation, and the effect is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected. The application of heat dissipation materials in the industry should not only focus on the heat dissipation coefficient, but ignore the thermal resistance value. If you only see that a certain heat dissipation patch, heat dissipation paste, heat dissipation paint or thermal conductive film has a good heat dissipation coefficient, you may think that high heat can be conducted out, and you may be disappointed. It is expected that the temperature will drop, the LED epitaxy will not decay due to overheating, the life of the LED street lamp can be effectively extended, and the acceptance will be passed smoothly. It may not happen.

     From this tedious process, it can be found that the material with the best thermal conductivity will also be defeated by the thermal resistance. Air, non-adherent pores at joints, heat dissipation pads, powder formed by the volatilization of heat dissipation paste silicone oil, and film thickness of multi-layer thermally conductive adhesive films will form thermal impedance. These multi-layer thermal resistances will hinder the heat conduction rate, the heat conduction is very slow, and even cannot be conducted to the surface of the LED lamp, and the heat will continue to accumulate and increase. The white backlight ink on the surface of the aluminum substrate must not only reflect, but also radiate the heat of the lower layer through the backlight ink on the surface.
