Ceiling lamp control circuit

The invention relates to a ceiling fan lamp control circuit. The ceiling fan lamp control circuit is composed of a rectification control unit and a ceiling fan lamp control unit; the rectification control unit comprises a transformer, a control power source module, a controllable rectifying module, a zero crossing detection module, a single-chip microcomputer control module, a triggering control module and a control setting module, and inputs a single-phase 220V alternating-current power source, and outputs controllable rectified voltage which has been subjected to voltage reduction of the transformer, and transmits ceiling fan lamp control signals containing ceiling fan speed level and lamp brightness level from the controllable rectified voltage; the ceiling fan lamp control unit includes an adjustment power source module, a waveform sampling module, a single-chip microcomputer adjustment module, a ceiling fan driving module and a lamp driving module, and inputs the controllable rectified voltage containing the ceiling fan lamp control signals so as to control ceiling fan speed and lamp brightness. With the method of the invention adopted, a remote controller is not required, and separate laying of control lines is not required, and a single-phase power line can be directly utilized to transmit the ceiling fan lamp control signals, and remote adjustment and control of a ceiling fan lamp can be realized.
