BRECKSVILLE, Ohio, May 18, 2011 — LED-based edge-lit illumination from Global Lighting Technologies Inc. offers an array of solutions for automotive lighting from backlit dashboard displays to interior and exterior lighting.
The company specializes in focusing the light emitted from white LEDs placed along one or more edges of a custom-designed lightguide and then efficiently extracting the light. The light extraction technologies employed enable bright and uniform light with the lowest part count possible.
Applications include backlighting of automotive interior displays such as digital instrument clusters, infotainment systems, global positioning systems displays, DVD players and other daylight-readable displays used in cars and minivans. The company also creates custom lightguides to illuminate heating, ventilation and air conditioning controls; park, reverse, neutral, drive and low-shift indicators; doorsills; dome and map lights; and accent lighting.
Edge-lit lightguides are also being used to illuminate manufacturers’ logos on the inside and outside of a car; they are employed also in a braking light system that has four lightguides, one on each side of the car and two in the trunk lid, to illuminate the well when the lid is opened.
