What parts does the general standard of led street light include?

　　① The conversion rate of light is 17% (the power output is 1000W, and the actual utilization rate is 170W).

　　② The street lamp lens material is an improved optical material, the light transmittance must reach ≥93%, and the temperature resistance is -38~+90℃.

　　③ The lens of the led street lamp, the spot must be rectangular, the material is PMMA optical material, the light transmittance is ≥93%, the temperature resistance is -38~+90℃, and the anti-UV yellowing rate is unchanged for 3000h.

　　④ The average illuminance of the road surface is 0.48, and the light spot ratio is 1:2.

　　⑤ The power facr of the LED street lamp must be above 0.9, and its power facr test value must be above 95% of the marked value, the tal circuit power must be within ±110% of the manufacturer's marked value, and the input current harmonic disrtion must not exceed the value specified in Table 8. , And the current tal harmonic disrtion must not be greater than 33%

　　⑥ Applicable humidity: ≤95%.

　　⑦ Quality assurance: 3~5 years.
