Therefore, the LED lamp mainly comprises an LED lamp bead and a driving part matched with the LED lamp bead. At present, most of wireless control lighting fixtures adopt an isolated or non-isolated switch type power supply circuit technology, particularly a flyback switch power supply is taken as a main technology, and the wireless control lighting fixture mainly comprises a rectifying circuit, a power stage circuit and a control circuit. These power stage circuits mainly include a switching tube, such as a triode. The LED constant-current driving power supply comprises a power stage circuit, a control circuit, a rectifier circuit, a control circuit and a control circuit, wherein the power stage circuit is used for converting voltage of alternating current commercial power, the alternating current commercial power enters the power stage circuit after passing through the rectifier circuit, the control circuit is used for controlling the on-off of a main power switch tube in the power stage circuit, and therefore constant-current driving of an LED to emit light is achieved.

Therefore, some wireless control lighting fixtures in the market adopt the technology, but because the circuit design arrangement or parameter setting (such as surge protection and overcurrent protection of the main circuit, and rectification, filtering, voltage stabilization and constant voltage, signal sampling and feedback and the like of each sub-circuit) is unreasonable, the stability and dimming and color mixing smoothness of the product are influenced to a certain degree in the actual use process of the lighting fixture, and the use experience of a user is influenced.
In addition, in actual production and application, in order to meet corresponding use requirements, a corresponding circuit needs to be built, for example, in order to meet the drive requirements of a white LED lamp bead, a dedicated drive circuit and a dedicated power supply circuit for supplying power to the drive circuit need to be built correspondingly, so that the circuit of the existing linear constant current drive circuit is complicated and low in flexibility, and cannot meet various personalized requirements in the market.
