Constant current source drive is the best way to drive LEDs. It uses constant current source to drive, no need to connect a current limiting resistor in the output circuit, and the current flowing through the LED is not affected by external power supply voltage changes, environmental temperature changes, and the discreteness of LED parameters. Therefore, the current can be kept constant and the various excellent characteristics of LED can be fully utilized. 

The LED constant current led power supply is used to supply power to the LED lamps. Since the current flowing through the LED will be automatically detected and controlled during the working period of the power supply, there is no need to worry about excessive current flowing through the LED at the moment of power-on, and no need to worry about the load short-circuiting. Bad power supply.

Since the LED emits a large amount of heat during the working process, the junction temperature of the die rises rapidly. The higher the LED power, the greater the heating effect. The increase in the temperature of the LED chip will lead to the change of the performance of the light-emitting device and the reduction of the electro-optical conversion efficiency. Therefore, the LED lamp must pay attention to the heat dissipation of the LED light source itself.

The SMARTS multi-current dial-up led power supply series is small in size and fast in heat dissipation. The working mode is constant current. There are multiple currents to choose from, which can meet the various needs of users.
