1.1 Lamp electrical performance When the LED street lamp is operated under the nominal rated power supply voltage and rated frequency, the difference between the actual consumed power and the rated power shall not exceed 10%, and the power factor shall not be less than 0.92.
1.2 Protection level LED street lamp protection grade A grade should not be lower than IP67; grade B grade should not be lower than IP66; grade C should not be lower than IP65.
1.3 Average life The rated life of LED street lamps should not be less than 30,000h.
1.4 Maximum temperature The rated maximum temperature Tc of the LED street light should not exceed 58 °C.
1.5 Maximum heat sink temperature The maximum heat sink temperature of each LED tube in the lamp should not exceed 65 °C.
1.6 Main light parameters
1.7 Immunity The voltage protection level of surge suppression performance (anti-lightning) should be no less than 2kV (line-to-line) and 4kV (line-to-ground).
1.8 Light distribution characteristics When some LED bulbs in the luminaire are extinguished or the whole lamp is dimmed, the spot shape and road illuminance uniformity should not change significantly.
