By eeNews Europe

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.
