People who do lighting projects are not unfamiliar with this problem. When maintaining the wall washer lighting project, the brightness of the outdoor wall washer just bought is obviously higher than that of the previous installation, so that in the later purchases Pay special attention to the problem of obvious brightness differences. Why is the brightness of the LED outdoor wall washer just bought higher than the original installation?
The most common causes of this problem are these 3:
1. The dust attached to the surface of the wall washer, because the lamp is installed outdoors, the dust in the air will accumulate on the tempered glass surface over time, causing the brightness of the lamp to attenuate.
2. The optical lens used in the wall washer is aging and yellowing. Now the commonly used optical lens materials are PC and PMMA. Such materials will appear aging and yellowing in high temperature environments, and the worse the quality of the selected materials, the appearance of The yellowing time is also faster.
3. The LED wall washer light decays. We all know that the LED light source will decay with the extension of the use time, and the longer the use, the faster the brightness will decrease. At the same time, the heat dissipation effect of lamps will also affect the speed of light decay. Xinyuanhui recommends that special attention should be paid to the heat dissipation of lamps when purchasing wall washers.
The above 3 points are the main reasons why the brightness of our newly purchased outdoor wall washer is higher than before. If you want to know more about the application knowledge of wall washer products, you can consult Chongqing Xinyuanhui Photoelectric Technology Co., Ltd. for details.
