    Abstract: The present invention provides a ripple compensation method and apparatus that provides a means to compensate for drive current ripple-induced brightness fluctuations in an LEE based illumination system. The ripple compensation apparatus comprises a ripple evaluation module which is configured to evaluate a ripple compensation factor based on an evaluated fluctuation of the drive current. The evaluation of the fluctuation of the drive current can be determined based on information collected during operation of the LEE based illumination system and/or based on predetermined operational characteristics of the LEE based illumination. A control system comprises the ripple evaluation module and is operatively coupled to the one or more light-emitting elements, wherein the control system is configured to determine and provide control signals for operation of the one or more light-emitting elements based on the ripple compensation factor.

The luminaire system further comprises an optical sensor system for generating optical signals representative of chromaticity and luminous flux output of the light. A heat sensing system is operatively coupled to the one or more arrays for generating signals representative of the junction temperatures of arrays of light-emitting elements during operation. The luminaire system further comprises a controller that is operatively connected to the current driver system, the optical sensor system and the heat sensing system for receiving the signals generated by each of these systems and is configured to generate one or more drive signals for transmission to the current driver system in response to the optical signals and thermal signals received from the optical system and the heat sensing system, respectively, thereby enabling a desired level of control of the output light.
