Identify inferior LED street lamps through several aspects

There are many manufacturers of LED street lamps on the market. The prices of lamps with the same power can vary several times. The prices of LED street lamps are very transparent from the outer shell to the accessories inside. The following introduces several characteristics of inferior LED street lamps, so you don’t want to drop them. Fall into the trap of low-quality lamps.



The efficiency of light-emitting chips is low. Now many brands of light-emitting chips have luminous efficiency above 140LM/W, and some low-end chips have luminous efficiency of 90LM/W. The efficiency of the whole lamp is very low. The consequence of low luminous efficiency is the large amount of heat generation. Under high temperature use, the life will be reduced a lot.



The heat dissipation effect of the radiator is not good. In order to reduce the cost, some street lamp manufacturers use inferior materials to conduct heat slowly, and the ventilation performance is not good. The lamp will be hot after the lamp is turned on for a while, which will seriously affect the power of the lamp and accelerate the light attenuation of the lamp. A good lamp housing has reasonable design, good heat conduction, fast heat dissipation, little change in temperature rise for a long time, and it will not be hot to the touch.


The selection standard of the drive power supply is low, and the service life of the power supply of the same specification is different due to different selection of accessories and different prices. High-quality power supplies generally have a warranty of more than 5 years and a service life of more than 7, 8 years. However, low-priced power supplies generally begin to be damaged in a large area after two years. If low-priced power supplies are used, the maintenance cost will increase a lot.
