Dimmer device with feedback function

A dimmer device adapted for use with an electric light source and a remote controller, said dimmer device enabling wireless control of intensity of light output of the electric light source and comprising a light dimmer adapted to couple electrically with the electric light source, said light dimmer including:

• a power supply module for outputting a supply power;
• a dimmer module coupled electrically to said power supply module and operable to vary the supply power to result in drive power that is supplied to the electric light source for driving operation of the electric light source to generate the light output;
• a feedback module for generating a feedback signal in accordance with the drive power supplied to the electric light source, the feedback signal corresponding to a current intensity of the light output of the electric light source;
• and
• a wireless bi-directional transmission module including a wireless receiver unit adapted to wirelessly receive a control signal from the remote controller and configured to provide the control signal to said dimmer module for controlling said dimmer module to vary the supply power in accordance with the control signal, and a wireless transmitter unit coupled electrically to said feedback module and configured to wirelessly transmit the feedback signal.
