Description

technical field [0001] The utility model relates to an electronic ballast for an AC high-power LED lighting energy-saving lamp, which belongs to the field of power saving for electric lighting. Background technique [0002] At present, in the field of electronic ballasts for electric lighting energy-saving lamps at home and abroad, there are mainly double-terminal high-voltage start-up electronic ballasts for fluorescent energy-saving lamps and trichromatic phosphor light-emitting energy-saving lamps, high-voltage mercury lamps, halogen tungsten lamps, and sodium lamps. ballast. Semiconductor high-power LED lighting energy-saving lamps have not been popularized and applied due to factors such as DC step-down drive, complex measurement and control parameters, strict requirements and expensive LED light-emitting devices. With a small amount of LED lighting energy-saving lamps, its structure is integrated. So far, there is no special electronic ballast for AC high-power LED l...
