摘要

A rectangular-cylindrical optical conductor grille (1) is complemented by two light sources and an ozone tube light (11), contained with the lamp. One of the light sources is an emergency light (2), illuminating on loss of mains supply, whilst the other (3) is conventional, being switched on continuously in normal use, and off on loss of supply. A parabolic reflector (4) and front plate are fastened internally, with a connection plate on the reflector. The reflector is moveable, and is fastened in the front region of the light source. A circuit board (7) provides electrical starter current and includes two conventional electrical connections.
