  • LED Driver Including Color Monitoring
    Publication number: 20120293078
    Abstract: A circuit provided for driving a multi-color LED assembly includes at least two LEDs operable to emit light of different color. The circuit includes a control and processing unit that is configured to select a source LED and a sensor LED from the LEDs of the multi-color LED assembly. A sensor unit is associated with the sensor LED and is configured to obtain a current measurement value representing the photo current provided by the sensor LED when receiving incident light emitted by the source LED. A LED driver unit is associated with the source LED and is configured to provide load current to the source LED in accordance with a corresponding input value.
