How to improve the service life and brightness of led street lights

Led street lights have been developed for many years. Nowadays, all the street lights on the road have been replaced with all-colored led street lights. Everything has a service life, including street lights. At the same time, the light attenuation of the led light source will increase every year. Then we should How to minimize the light attenuation, in fact, when we buy led street lights, we should consider the following aspects:

1. The LED street light source adopts the patented structure of Bridgelux or Corey, the chip is placed on the pin, and the heat energy is directly discharged from the chip node through the silver pin, which is the same as the traditional in-line product and traditional The SMD products are qualitatively different in terms of heat dissipation, and the node temperature of the chip will not accumulate, thus ensuring the good usability of the light source lamp beads, ensuring the long life and low light attenuation of the light source lamp beads.

2. The primary requirement of the power supply is high efficiency, high efficiency products, low heat generation, high stability. Usually there are two options of isolation and non-isolation in the power supply part. The isolated volume is too large and the efficiency is low. There will be many problems in use and installation. The market prospects of non-isolated products are not as big as non-isolated products. Here we mainly discuss non-isolated products. Drive scheme.

3. The introduction and application of infrared radiation heat dissipation to fluorescent tubes is an important means to improve the service life of tubes. In consideration of heat dissipation, we separate the heat dissipation of the LED street light source lamp beads and the heat dissipation of the power supply, and do not interfere with each other, so as to ensure the rationality of heat dissipation.

In short, taking the above three points into consideration, the use of well-known brand lamp beads, aluminum substrate, lens, and power supply can only be solved from the source, because it has a longer service life than ordinary brand LED street lights. Brighter, these are also necessary methods for the life and brightness of led street lights.
