技术领域technical field
本实用新型涉及一种多功能的节能LED灯控制电路。The utility model relates to a multifunctional energy-saving LED lamp control circuit.
背景技术Background technique
现有的节能LED灯，虽然能调节亮度，但是一般采用恒压电源驱动LED模组，因此亮度的一致性较差，另外，功能较为单一，只能作为光源使用，不具有其他新颖的功能。因此，有必要设计一种新型的LED控制电路。Although the existing energy-saving LED lamps can adjust the brightness, they generally use a constant voltage power supply to drive the LED modules, so the consistency of the brightness is poor.
