New Applications with High Flux LED in Automotive Signal Lighting

Light Emitting Diodes (LED) in the field of automotive signal lighting have been well known for around a decade. The first step was the introduction of Central High Mounted Stop Lamps (CHMSL), containing 5 mm LED types with an emitter-flux of less than 1 lm. Improved designs offering more than 2 lm have made new CHMSL designs, side-markers, and the first rear combination lamp functions possible.

The development of the next LED generation, supplying more than 10 lm, will extend LED technology into new fields of application. Concentrated in one LED package, this offers two new areas of application:

• Signal functions requiring a high amount of flux to reach the photometrical requirements.
• Designs working with indirect lighting in order to create new styling variations.

This paper will attempt to show the wide field of possibilities that can be opened up with new LED types, in combination with innovative optical systems.
