1) Direct drive: THE COB LED module is connected to the fixed current LED driver. The brightness and current of the lamp are controlled by the LED driver. As the main force in the market, most of them are high-efficiency, high-power lamps

2) Simple current-limiting circuit built into the lamp strip :12V or 24V LED strip is used with constant voltage power supply. The current on the lamp strip is determined by the resistance between voltage and LED or simple transistor current-limiting circuit, which is mostly used for indirect lighting and low-power direct lighting applications.

3) External or built-in voltage: The current converter USES a fixed-voltage power supply. In the middle, a voltage-current converter is used to output the fixed current to the LED module. The current is mainly controlled by the intermediate voltage-current converter (DC to DC). Similar to distributed-power applications, a high-power driver provides power, and a back-stage voltage-current converter limits LED current.
