Abstract

Provided in the present disclosure are a drive circuit, a drive controller, and a lamp. The drive circuit comprises a load module, an energy storage module, a constant-current control module and a sampling signal module, wherein the load module comprises a first load and a second load, which are connected to a power supply module; the energy storage module is connected to the first load, the power supply module charges the energy storage module, and the energy storage module can supply power to the load module; the constant-current control module comprises a first control unit and a fourth control unit, which are connected to the second load in parallel, and a second control unit and a third control unit, which are connected to the second load in series; and the sampling signal module comprises a diode D1 and a sampling module, which are arranged between the power supply module and the energy storage module, the sampling module sampling an output voltage of the power supply module and controlling the connection or disconnection of the first control unit, the second control unit, the third control unit and the fourth control unit. In the present disclosure, an energy storage module and a constant-current control module are configured, such that a load can realize constant-current output when a voltage fluctuation is relatively large, thereby avoiding stroboflash of a lamp bead during the voltage fluctuation.
