LED street light power supply may be heard more, but the LED constant current power supply may be a bit embarrassing, I do not know what kind of power is this. In fact, LED street light power supply generally refers to constant current power supply, then what is the LED street light constant current power supply? Zhongfu Optoelectronic LED Street Light Power Supply Factory tells you:



According to Xiaobian, LED constant current power supply is a power supply device that can supply constant current to the load. It can keep the output current constant when the external power supply generates fluctuations and impedance characteristics change. The constant current source circuit has the characteristics of constant output current, good temperature stability, small DC resistance, but large equivalent AC output resistance.

The range of the constant current power supply is approximately 1μA to 20A. It can provide bias current for various amplifying circuits to stabilize its static operating point and as its active load to increase the amplification factor. And it has also been widely used in differential amplifier circuits and pulse generation circuits.

Constant current can also be called steady flow, meaning similar, generally can be no difference. Compared with the concept of constant voltage, the concept of constant current is difficult to understand, because constant voltage sources are common in daily life, batteries and dry batteries are DC constant voltage power supplies, while 220V AC power can be considered as an exchange. Constant voltage power supplies, because their output voltage is basically constant, does not vary greatly with the magnitude of the output current.
