Distinguish the quality of LED tri-proof lights
LED tri-proof lamp has many advantages such as high luminous efficiency, long life, no delay in switching, environmental protection and energy saving. It is an advanced lighting product that gradually replaces energy-saving lamps, metal halide lamps and other light sources. However, due to the uneven quality of manufacturers, there will also be some quality problems. , the common reasons for the damage of inferior three-proof lamps are roughly as follows:
1). The power supply is bad; due to the power supply problem, some manufacturers use inferior power supplies due to chasing the products at low prices, and the quality of the products is unqualified.
2. The light source is bad; the assembly process of the lamp is not perfect, the lamp bead and the heat sink cannot be in good contact, and the thermal paste is not uniformly applied. In addition, if the quality of the lamp bead itself is poor, it will burn for a long time.
3) The radiator cuts corners and cannot achieve good heat dissipation. Cause the lamp temperature to rise too high too fast.
The repair methods for damaged tri-proof lights generally include the following:
The SMD type can replace the entire light board, and the high-power integrated type can replace the entire light source. It should be noted that heat conduction and heat dissipation must be handled well. If the power supply fails, you can only replace it with a new one.
