OPTICAL SIGNALING OR DISPLAY DEVICE

摘要

The arrangement has a rastered light field with a matrix of grouped light sources controllable individually, in groups or as a whole, esp. LEDs (14), on a printed board (10) and a lens system with a spatially defined light distribution. The lens system contains at least one scattering lens (12) extending over the entire light field and of externally flat profile and with internal parallel grooves (18) with at least partially asymmetrically curved surfaces (26). The plane region is slightly angled between the grooves. An Independent claim is also included for a method of monitoring the light intensity of the arrangement.
