Abstract:
Disclosed is a lighting device, including at least partially reflective electroactive polymer actuator and a lighting element illuminating the electroactive polymer actuator. A voltage control arrangement for driving the electroactive polymer actuator with a spatially varying voltage distribution is provided. This way, the curvature and alignment of the reflective surface of the electroactive polymer actuator can be adjusted as needed, thereby providing an optimized beam pattern for the relevant field of application.
