Indication/signaling device has light source(s), focusing, transparent body(ies) for total reflection of light into horizontal plane; incident sunlight passed through surface(s) is absorbed in signal

摘要

The indication and signaling device closely focuses light from one or more sources (2) and directs it onto one or more surfaces of one or more transparent bodies (1) for total reflection at the one or more surfaces into the horizontal plane (7). Sunlight (9) incident on the one or more surfaces within a large angular range is passed through the surface(s) and absorbed into the signal.
