Although the structure of the LED lamp holder looks very simple, it actually has some technical content in it. In the following, a detailed analysis and introduction is made for the special technical requirements of LED lamp holders. Let's get a detailed understanding together.

1 Lamp electrical performance When the LED lamp holder works under the nominal rated power supply voltage and rated frequency, the difference between the actual power consumption and the rated power should not be more than 10%, and the power factor should not be less than 0.92.

　　2 Protection level The protection level of LED lamp holders A-level products should not be lower than IP67; B-grade products should not be lower than IP66; C-grade products should not be lower than IP65.

　　3 Average life The rated average life of LED lamp holders should not be less than 30000h.

　　4 Maximum temperature The rated maximum temperature Tc of the LED lamp holder should not be greater than 58℃.

　　5 Maximum heat sink temperature The maximum heat sink temperature of each LED tube in the lamp should not be greater than 65°C.

　　6 Main optical parameters

　　7 Immunity The voltage protection level of surge suppression (lightning resistance) should not be lower than 2kV (line-line) and 4kV (line-ground).

　　8 Light distribution characteristics When part of the LED lamp holder in the lamp is extinguished or the entire lamp is dimmed, the spot shape and the uniformity of the road illumination should not change significantly.
