Indicating road sign esp. for road traffic with multiple of illuminated points - representing varying symbols and/or texts and at least one optical system, e.g. combination of lenses, is provided at light output end of each illumination point

摘要

The optical system (5,6) effects a deflection of the radiated light (L1,L2) in a predetermined region (II). The latter is the half space underneath the horizontal (4) of the illumination point (1). The optical system can consist of a lens (5) or a diffusing disc (6) or a combination of both. ADVANTAGE - Illumination power of indicating sign at place of observer can be increased with same or reduced energy consumption, or ensures illumination power with reduced energy consumption.
