Warning light for road accident - uses laser at angle to vertical rotated about central vertical axis

摘要

The warning light uses a laser (1) contained in a housing (8) with its axis at a small angle (alpha) to the vertical. The laser (1) is rotated about a central vertical axis (12) to describe a cone, under control of an electric motor. Pref. the housing (8) is free-standing and incorporates the electric motor and the electrical ignition and operating circuit for the laser (1) in its base, fitted with a transparent belt-shaped cover (9). Pref. the latter is made of glass. ADVANTAGE - Provides warning light signals which can be seen around bends.
