Abstract
The utility model provides an LED control circuit. The LED control circuit comprises a DCDC circuit module, a start-stop module, a logic module, a first LED load and a second LED load, and is characterized in that the start-stop module is connected with the DCDC circuit module, the DCDC circuit module is connected with the first LED load, the first LED load is connected with the second LED load, and the second LED load is connected with the logic module. According to the LED control circuit, the DCDC circuit module supplies power to the first LED load and / or the second LED load, when the first LED load and / or the second LED load works, the DCDC circuit module is firstly closed through the start-stop module, then the first LED load and / or the second LED load are adjusted to work through the logic module, and finally the DCDC circuit module is started through the start-stop module. The LED control circuit provided by the utility model can avoid the generation of transient peak current, and effectively prolongs the service life of an automobile lamp and reduces potential safety hazards especially when the LED control circuit is applied to automobile light.
