Gentex Corporation has begun shipping its proprietary light-emitting diodes (LEDs) within high-feature, interior auto-dimming rearview mirrors for the 2003 Chrysler Sebring coupe.

Each mirror contains a map light serving the driver and front seat passenger, using binary complementary white (BCW) light versions of Gentex’s Orca power LEDs in a highly engineered module. Additional features include the automatic-dimming electrochromic mirror function, Johnson Controls’ Homelink wireless control system, and a dual-display showing the external temperature and the vehicle’s compass heading, generated by Johnson Control’s PathPoint compass technology.
“We are delighted to have simultaneously launched production of Orca power LED components in our pilot facility at the same time we’ve introduced a state-of-the art, multi-featured application designed around these components,” said Gentex executive vice president Kenneth La Grand.
Each of the patented BCW Orca power LED components used in these assemblies typically produces in excess of 7.5 lumens of white light operating at about 0.6 watts. The LEDs are assembled into circuit assemblies using conventional tape-and-reel feeders, standard radial insertion equipment and a normal wave-soldering process, making them the most powerful, white LED components compatible with standard electronic assembly processes in production today.
Prior to introduction of Gentex’s first BCW LED illuminator in 1998, a map lamp feature typically required two 4.25 watt incandescent lamps along with associated vents and bulky optics. LEDs typically last longer than a vehicle, potentially reducing warranty costs for the automaker and eliminating a need to design for replacement.
