Because the constant current source drive, do not need in the output circuit series current limiting resistance, LED through the current is not affected by the external supply voltage change, environmental temperature change, as well as LED parameter dispersion, so that the current can maintain constant, full play of various excellent characteristics of LED.
LED constant current power supply is adopted to supply power to LED lamps. Due to the automatic detection and control of the current flowing through LED during the power supply, there is no need to worry about too high current flowing through LED in the moment of power supply, and no need to worry about the load short-circuit burning power supply.
