Abstract (en)
[origin: WO2009114646A2] The present invention provides LED array systems with improved methods of powering LED in the array by monitoring the relationship between temperature and driving power to predict how much power can be safely applied to the LEDs. The present invention also provides for a control system for LED arrays that allows for display of images or light patterns across and array of luminiairs over a low bandwidth control protocol. The present invention also provides for a LED array luminair with reduced color fringing, light spill reduction and beam angle control.
