In the past, ambient lighting was all about aesthetics. Today, new innovations combine emotion and functionality. Communication between vehicle and passenger is becoming more and more important, especially with the advancement of autonomous driving.
Lighting in the passenger compartment has now specific tasks, like the visual indication of functions and warnings in the vehicle. Ambient lighting is increasingly becoming functional light.
Smart LED lights that can change color and brightness while they are small enough to be installed in a range of space limited configurations. This enables designers to illuminate interiors and instruments in previously unimaginable ways to increase comfort and safety.
Functional lighting can be implemented to warn pedestrians or the driver of a situation, use the steering wheel as HMI (Human Machine Interface) in ADAS systems, for external displays in autonomous taxi/buses or dynamic daytime running lights (DRL) for communication.
FUNCTIONAL LIGHTING APPLICATION EXAMPLES
- Steering Wheel – HMI in ADAS systems
- External display for autonomous taxi/buses
- Dynamic Daytime Running Lights (DRL) application for pedestrian communication
- Low cost system
- No LED binning
- Bidirectional control
- Flexible design
- ASIL C or D
- Low EMI
- Built-in Diagnostics
