Abstract
The invention discloses an LED driving power supply circuit, which comprises a light modulation unit, a control unit, a communication unit and a power supply unit, wherein the light modulation unit issued for receiving a first light modulation signal sent by a light modulator and filtering the first light modulation signal; the control unit is connected with the light modulation unit, and is used for outputting a second light modulation signal to power supply voltage for light modulation according to the first light modulation signal and communicating with a CD-R machine to output a corresponding feedback signal according to a burning signal sent by the CD-R machine; the communication unit is connected with the control unit, and is used for feeding back the feedback signal output by the control unit to the CD-R machine; the power supply unit is connected with the control unit, and is used for supplying power to the control unit; and the light modulation unit, the control unit, the power supply unit and the communication unit are all connected to a multiplex interface for connection of the light modulator or the CD-R machine. The number of interfaces and the number of connection wires can be reduced; the cost can be reduced; and the structural design can be optimized.
