UK - Color Kinetics Inc has been issued with two new US patents relating in part to LED-based illumination systems designed to generate colour changing effects in enclosures, and to the use of LED-based light sources to convey information about temperature changes of a device. US Patent number 6,888,322 (issued 3 May), is directed to a colour-changing enclosure where illumination is provided by multicolour LED-based sources. The colour-changing device could form part of a neon replacement system, tile light, consumer product, computer, peripheral or accessory, for example.

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."
