LED high-power industrial and mining lamps have many advantages such as high luminous efficiency, long life, no delay in switching, environmental protection and energy saving, etc. They are the most advanced lighting products that gradually replace energy sources such as energy-saving lamps and metal halide lamps, but they may also appear due to different manufacturers. Some quality issues.
1. The light source is bad; the process of the lamp is not perfect when assembled, the lamp bead does not have good contact with the heat sink, and the thermal paste is unevenly coated. In addition, if the quality of the lamp bead itself is poor, the lighting time will burn off.
2. The power supply is bad; the power supply problem causes some manufacturers to use the inferior power supply because of the low price of the product. The quality of the product is unqualified. After a long time of use, the lamp will be burned, the light will flash or the light will be on for a while.
3. The radiator cuts the work and can not achieve good heat dissipation. The temperature rise of the lamp is too high and too fast.
