LED-based edge lighting for automotive illumination

May 10, 2011 // By Julien Happich
Global Lighting Technologies offers an array of innovative and highly efficient solutions for automotive lighting from backlit dashboard displays to interior and exterior lighting. LED-based edge-lit illumination focuses the light emitted from white LEDs placed along one or more edges of a custom designed light guide and then extracts this light in a highly efficient and uniform manner.

The light extraction technologies employed by GLT enable what the manufacturer claims to be the brightest, most uniform light with the highest efficiency and lowest part count possible.

Applications include backlighting of automotive interior displays such as digital instrument clusters, infotainment systems, GPS displays, DVD players and other daylight-readable displays used in cars and minivans. GLT also creates custom light guides to illuminate HVAC controls, PRNDL shift indicators and door sills as well as dome lights, map lights, and accent lighting. Edge-lit light guides are also being used to illuminate manufacturers' logos on the inside and outside of a car, as well as in an innovative braking light system that employs four light guides, one on each side of the car and two in the trunk lid, to illuminate the well when the lid is opened.
