Constant current LED street light

In order to make the LED street lamp power supply work in the range of AC85-265V with a wide input voltage range, the series-parallel mode of the LEDs of the lamp board is very important. Try not to use a wide voltage, and it can be divided into AC220V and AC110V as much as possible, so as to ensure the reliability of the power supply. There is also a wide voltage solution, APFC active power compensation is to use L6561/7527 to raise the voltage to 400V first, and then step down, which is equivalent to two switching power supplies. This program is only used under certain conditions.

Advantages of LED Street Lights:
The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions.
Long life: It can be used for more than 50,000 hours and provides three-year quality assurance. The disadvantage is that the life of the power supply cannot be guaranteed.
High light efficiency: Using chips ≥100LM, it can save energy by more than 75% compared to traditional high-pressure sodium lamps.
Easy to install: no need to add buried cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp housing.
