LED industrial and mining lights have many advantages such as high light efficiency, long life, no switching delay, environmental protection and energy saving. It is an advanced lighting product that gradually replaces energy-saving lamps, metal halide lamps and other light sources. The common reasons for the damage of common inferior industrial and mining lamps are as follows:
1). Power supply is bad; power supply problems cause some manufacturers to chase products at low prices and use inferior power supplies. The quality of the products is unqualified. After a long period of use, the lamp will burn, the lamp will flash or flash for a while.
2. The light source is bad; the process of assembling the lamp is not perfect, the lamp beads cannot be in good contact with the heat sink, and the thermal conductive paste is unevenly coated. In addition, if the quality of the lamp bead itself is poor, it will burn out for a long time.
3) Radiators cut corners and cut materials, which cannot achieve good heat dissipation. Causes the temperature of the lamp to rise too high and too fast.
The repair methods for damaged industrial and mining lights are generally as follows:
The patch 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 treatment and heat dissipation must be done. If the power supply fails, you can only replace it with a new one.
