Description

technical field [0001] The invention relates to LED control circuit technology, in particular to a compensation driving device and a realization method thereof. Background technique [0002] With the continuous development of society, the lighting industry is changing with each passing day. As a replacement of incandescent lamps, energy-saving lamps and other non-energy-saving light sources, LED lighting products are favored by more and more consumers due to their long life, no pollution, and the advantages of green environmental protection and energy-saving lamps. . For lighting products, in addition to their own lighting functions, people also have higher and higher requirements for their electrical performance and service life in various environments. requirements become more stringent. [0003] Facing the increasingly competitive LED lighting market, the cost of LED lighting products continues to decrease, the functions continue to increase, and the stability of produc...
