OSRAM Opto Semiconductors Inc.

“Color On Demand”

Osram has over 30 years of experience in opto semiconductor technology and phospors. They are working on a number of new applications in automotive and non-automotive uses, such as cell phones, white goods, and general and decorative lighting. An innovative new idea in vehicle brand personalization, however, is “Color on Demand” interior lighting, developed by Osram Opto Semiconductors. This breakthrough is made possible by development of a single LED capable of being customized to give off specific unique luminescent colors throughout the interior of a vehicle.

The process is based on use of blue LED applications combined with a series of red and green phospor converters to produce a vast spectrum of colors. The fine-tuning of these phosphors make it possible to offer manufacturers a new, distinctively recognizable way to give their brands unique, identifying personalities. Up until now, creation of saturated colors was possible only by use of expensive electro-luminescent materials or multiple color LEDs.

The result is capable of providing manufacturers with a new form of branding signature, as well as dramatic driver experience, and giving the consumer attractive interior lighting harmony along with the advantages of LED technology, meaning high reliability, long life, low power consumption, and low cost.

The first commercial adoption of this innovation is the 2006 Chevrolet HHR, Monte Carlo, and Impala. The instrument cluster, radio buttons and a number of backlit switches are characterized by the color “Blue Lagoon,” selected by the OEM. A number of other OEMs will implement this feature on 2007 vehicles and beyond, each with a distinctive color signature.
