Patent ID: 7893631

Claim:
A luminaire system configured to generate white light with a desired correlated colour temperature, the luminaire system comprising: a) a light module including: i) one or more white light-emitting elements configured to generate a first white light having a particular correlated colour temperature; ii) one or more first colour light-emitting elements configured to generate light of a first colour; iii) one or more second colour light-emitting elements configured to generate light of a second colour, wherein the one or more white light-emitting elements are configured to generate the first white light independent of each of the light of the first colour generated by the one or more first colour light-emitting elements and the light of the second colour generated by the one or more second light-emitting elements; b) a feedback system configured to collect operational temperature information regarding the light module; c) a drive and control system configured to receive said temperature information, and configured to control the supply of power to each of the one or more white light-emitting elements, the one or more first colour light-emitting elements, and the one or more second colour light-emitting elements based on the temperature information and the desired correlated colour temperature; and d) an optical system configured to extract and mix the light generated by the light module thereby creating an output beam of a second white light having the desired correlated colour temperature, wherein the one or more first colour light-emitting elements and the one or more second colour light-emitting elements are arranged in relationship with the one or more white light-emitting elements to provide the second white light having the desired correlated colour temperature when the light generated by the light module, including the first white light having the particular colour correlated temperature is extracted and mixed.
