1. High-power LED wall washer lamp beads, the quality of LED lamp beads affects the heat dissipation performance of LED floodlights. For example, the lamp beads of first-tier brands and third-tier brands not only have many differences in light efficiency, but also have a large gap in heat dissipation performance. .
2. The environment in which the outdoor LED wall washer is located: when the working temperature of the wall washer shell exceeds the working temperature by 10 degrees, the service life of the wall washer lamp is reduced by half; the working temperature of the LED wall washer shell is normally 65 degrees.
3. The material and thickness of the outdoor LED wall washer shell, the aluminum material has much better heat dissipation performance than the iron material. In addition, there are many kinds of aluminum materials. The thicker the shell, the faster the heat dissipation.
Fourth, the heat conduction medium in contact with the LED lamp bead and the shell, which also restricts the heat dissipation performance of the high-power LED wall washer.
