Introduction to technical requirements of solar street light

1. The electrical performance of the lamp, when the solar street light 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 greater than 10%, and the power factor should not be less than 0.92. 2. Protection grade, solar street light protection grade A should not be lower than IP67; B grade should not be lower than IP66; C grade should not be IP65. 3. Average life, the rated average life of solar street light should not be less than 30000h. 4. The maximum temperature, the rated maximum temperature Tc value of solar street light should not be greater than 58℃. 5. The maximum heat sink temperature, the maximum heat sink temperature of each LED tube in the lamp should not be greater than 65 ℃. 6. Main optical parameters 7. The voltage protection level of immunity, surge suppression performance (anti-lightning strike) should not be lower than 2kV (line-line) and 4kV (line-ground). 6. Light distribution characteristics, when some of the LED bulbs in the lamp are extinguished or the lamp is dimmed, the shape of the spot and the uniformity of the road illumination should not change significantly.
