发明名称 AMBIENT LIGHT COMPENSATION SENSOR AND PROCEDURE
摘要 The present invention relates to a solid-state based light source, a corresponding circuitry and a method of emitting light, including one or more light source elements for generating light, a first sensor for receiving light emitted by the light source elements and ambient light and for generating a first sensor signal (S1) representing the received light, a second sensor for only receiving ambient light and for generating a second sensor signal (S2) representing the received ambient light. Moreover, the solid-state based light source comprises a control unit for receiving the first and the second sensor signals (S1, S2) and for generating control signals (Sc) for controlling the light source elements, based on the difference between the first and the second sensor signals (S1, S2), to compensate for the influence of the ambient light.
