Light-emitting chips are inferior products, which is reflected in the luminous efficiency. The luminous efficiency of a single chip is 90LM/W, and the efficiency of the whole lamp is even lower. Generally, it is below 80LM/W. Now the light-emitting chips of Led Street Lamps Suppliers must be at least 140LM/W. , This is incomparable, and some people say that it doesn’t matter if the efficiency is low, it can be bright, but what they don’t know is that it will generate a lot of heat. After a long time, the light decay will expand rapidly. It will not take a year or two, and it will basically need to be scrapped.
Secondly, the choice of driving power supply, the power supply of the same specification is due to the different selection of accessories, the price gap is too large, and the service life will also vary greatly. Low-priced power supplies generally start to be damaged in a large area after two years, but high-quality power supplies generally have a warranty of more than 5 years, a service life of more than 7 or 8 years, and the cost of maintenance is greatly reduced.
Thirdly, the design and materials of the radiator are also very important. The heat dissipation design of good lamps is scientific and reasonable, and the heat dissipation is fast. It will be hot, it will also affect the normal power of the lamp, and it will accelerate the light decay of the lamp.
