摘要：a lamp includes a reflector with a concave reflective surface and an axis ofrotation, and a light source provided with a filament mounted at a focal point of thereflecting surface or in the vicinity thereof. the length \\/ diameter ratio of the filament is6: 1 or more.the reflecting surface is in the form of a plurality of reflective facets.at least50 per cent of the reflecting surface, the sides are curved and dimensions chosen so as toproduce a pattern of light so that a ratio between the distribution generated by thefacets according to the width of the filament and the salt produced by cutting the lengthof the filament is less than 2: 1.the facets are preferably arranged in adjacent rings fromthe point of view of performance. the rings may be sequentially shifted in a cuttingdirection of rotation to reduce the variations in the circumference of the pattern of light.
