Description

technical field

[0001] The invention relates to LED drive and control circuit technology, in particular to a dimming control device and an implementation method thereof. Background technique

[0002] With the global phase-out of incandescent lamps and the implementation of energy-saving and emission-reduction policies, LED lighting has been rapidly popularized and penetrated. At the same time, the LED drive power supply, which is a key component of LED lighting, also has a broad market prospect. Nowadays, the LED market and technology are gradually mature, and its application has fully penetrated into various fields. Under such a big environment, the entire LED lighting market is trying to reduce the cost of LED products in order to improve the market competitiveness of products. As the cost of LED products decreases, the price of the driving power supply, which is the "heart" of LED lamps, also decreases.

[0003] Some 0-10V dimming solutions on the market are implemented...
