How much is the power supply voltage of street lamp LED?
220V AC through the LED power, converted to DC 35V voltage supply to the chip, LED chip can only withstand DC 35V voltage!
LED Street bus will use two kinds of voltage, a two-phase 220V alternating current, applied to a line and thirty street lights, another is 220V three-phase alternating current, applied to a line and more than thirty sets of lights.
You should ask the power output voltage, to see what you are used, for example, you choose the constant voltage power supply, the output is generally 12V, 24V two, is 24V, if you choose the constant current power supply, the power supply and your W number is the number of MA, general the lamp should be more than 700MA,
