  • Patent number: 10314128
    Abstract: A dimming control power supply for LED lamps, comprises a first secondary power supply module, an output control module, a PWM signal receiving module, and a control signal converting module. The output control module is configured to adjust the output current according to the received constant DC voltage signal with a variable amplitude. The control signal converting module converts the PWM signal received by the PWM signal receiving module into a constant DC voltage signal with a variable amplitude. The output control module adjusts the output current according to the constant DC voltage signal with a variable amplitude to adjust the brightness of the LED lamps. The light source provided by the LED lamp powered by the dimming control power supply for the LED lamps doesn't form streaks in the photographs taken by the cell phone or the camera and thus enhances the user's light experience.
