US Patent number 6,883,929 (issued 26 April), is directed to generating power for LED-based light sources based on a thermoelectric process called the Seebeck Effect, which allows a temperature differential to generate electricity. For example, the invention may be used in a stove where the temperature of the stove top is conveyed through the colour of light emitted by a multicolor LED-based source, say the company.
George Mueller, chairman and CEO of Color Kinetics, said: "Color Kinetics continually looks to innovate new technologies and methods that will allow completely new uses of intelligent solid-state lighting, for example, to create dynamic or customizable color changing enclosures. Beyond the replacement of conventional light sources in traditional applications, we are shaping completely new, intelligent uses of light with exciting market potential."
