Abstract

The invention relates to a light unit, comprising a concave reflector (7) with an outlet opening and an axis, whereby the reflector encloses a light source running in the direction of the axis. The light source is enclosed at a separation from an open-ended cylindrical protective tube (16), with a glare shield (19), provided at the open end of the protective tube. The glare shield (19) is a sheet, cupped over the burst-protection tube, whereby the glare shield comprises a semi-circular end piece with a given maximum diameter, on which a straight cylindrical section of greater diameter is mounted which itself is further provided with an offset screen (21).
