Adaptive Lighting Functions History and Future - Performance Investigations and Field Test for User's Acceptance

2002-03-04
2002-01-0526
Adaptive Lighting Systems approach the market by showing additional value to the customer. Different possibilities are discussed like additional modules that are switched on, light sources with power controlled luminous output (‘“dimming”) or modules which are enabled to swivel parts of the light distribution or swiveling the full light distribution itself. The result can be measured in photometric parameters as luminous flux, candelas or lux or as well in geometrical parameters as range, sidespread, covered area etc. This paper will add to the usual photometric discussion of the new technologies another aspect: The way a standard driver experiences and accepts the new and rather unused technology of adaptive lighting systems.

The Continuous Emerging of LED in Headlamps: Challenges and Technical Solution for LED Fog Lamps

2006-01-0103
After the first series applications with LED in headlamp signal functions are on the road or close to production release, the next continuous steps are considered in the paper. Side markers and Position lamps, Daytime Running lamps and Turn Indicators are considered to be in a technology ready status. Despite the fact that fog lamps have low luminous flux and photometrical requirements, the challenges due to glare avoidance and aimability via cut off line have reached a new level. Technical concepts and performance will be discussed with measurement data evaluation. Due to the fact that different LED suppliers are on the market with different optical and mechanical solutions, a matrix evaluation will be driven for photometrical and efficiency potential. Another significant impact will be the styling influence of the exit apertures. Studies for LED fog lamps will be presented. Several LED sources require a dedicated electronic driving concept.

Ideas for Next Lighting Generations in Digitalization and Autonomous Driving

Digitalization in Industry and Society is progressing quickly. Up to now, just 5 static and standard lighting applications have been dominating in the U.S. (Low/High Beam, Daytime Running Lamp Turn Indicator & Position Lamp). The global interest in standardization of light driven messages from autonomous vehicles to other traffic participants has opened new research needs and research findings. In Europe, GTB has established a working group dedicated to this topic. The article will discuss the possible contribution of signalling and lighting functions to Digitalization and Autonomous driving by explaining the first elements of functional definition and research results.
