Abstract
Systems and methods for processing a material layer supported by a substrate using a light-source assembly that includes LED light sources each formed from an array of LEDs. The material layer is capable of undergoing a photo-process having a temperature-dependent reaction rate. Some of the LEDs emit light of a first wavelength that initiate the photo-process while some of the LEDs emit light of a second wavelength that heats the substrate. The heat from the substrate then heats the material layer, which increases the temperature-dependent reaction rate of the photo-process.
