Spectral-Metal Coating LED Application
Oct 2007
Deposition Sciences Inc. (DSI)Request Info
SANTA ROSA, Calif., Oct. 22, 2007 -- Deposition Sciences Inc. (DSI), announced its advanced Spectral Metal thin-film coating has a new application: In LED light-signaling marine lanterns.

Collaborating with LED lantern and buoy maker Automatic Power of Houston, DSI customized a white-light reflecting version of the dichroic hybrid Spectral Metal coating for use in the company's LED LR Marine Lantern and light signaling system. The resulting high-intensity LED LR Marine Lantern range is in excess of 12 miles (greater than 17.5 miles in areas with higher transmissivity) and the lantern takes advantage of the advanced thin-film coatings' high reflectivity, durability and cost effectiveness, DSI said.

DSI's capabilities include coating Spectral Metal in large, flat sheets, cutting it to size and forming precise parabolic shapes to meet the requirements for Automatic Power's LED lantern application. The new high-brightness system uses parabolic mirrors made from Spectral Metal that is formed to fit an aluminum extrusion. These specially formed, Spectral Metal parabolic mirrors are used to steer the output of onboard LEDs into a precise pattern.

The company's reliable and cost-effective coating technique produces the precision mirror that is required to get maximum collection efficiency from the LEDs, DSI said. The precise shape of the mirrors, coupled with the high reflectivity of DSI's Spectral Metal product permits the fixture to meet the high intensity (12-mile minimum visibility) requirements for these marine lanterns.

DSI said it is currently working with other manufacturers in the areas of medical illumination, solid-state lighting, solar energy production and general illumination to use Spectral Metal into their next-generation products. DSI said its proprietary MicroDyn sputtering technology yields high performance, highly durable optical coatings that are extremely stable over temperature and humidity changes, meeting or exceeding many established military and aerospace standards.
