Led Street Light Factory Analysis Of Product Life - 11-14-2019, 07:46 PM

In the field of road traffic, LED street lamps, as a new energy-efficient lighting product, have been highly sought after by users since its inception. However, in practical applications, LED street lights still have many problems. Today, our professional Led Street Light Factory to analyze the specific: How does temperature affect the life of LED street lamps?

In theory, the total electro-optical conversion efficiency of an LED is about 54%, and the remaining electrical energy is released outward in the form of thermal energy. However, based on the current state of the art, the higher electro-optic conversion efficiency is less than half of the theoretical value. Therefore, for LED street lamps, when the heat accumulates to a certain extent, excessive temperature will have a direct impact on the performance of the LED street lamps, thus affecting the overall service life of the lamps.

When the temperature rises, the light efficiency of the LED chip will decrease; the correlated color temperature of white light will increase, the correlated color temperature of other colors will decrease, and the visual deviation will occur; the epoxy resin material of the LED package will turn yellow, the transparency will be deteriorated, and cracks and water vapor will easily occur. From the cracks into the electronic components...
