Description

technical field [0001] The invention relates to the field of LED lamp power supply circuits, in particular to a medium-power combined dimming LED driving power supply. Background technique [0002] The invention relates to the technical field of LED driving power supply, in particular to a small and medium power (20W-70W) control two-way complementary LED driving power supply circuit. General low-power LED lighting power supply, due to price reasons, most of them use one or only two color temperature adjustment states, can not control the control of more than two color temperatures, the accuracy is not high, but the combination of two products can achieve the desired effect, but the cost will also increase, and the application is greatly restricted. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a medium-power combined dimming LED ...
