Abstract

A reflector is described which has a focusing device and a cylindrical part which accommodates a lamp mount and onto which it is possible to push a focusing ring which is screwed to a reflector holder via a thread and can be rotated relative to the cylindrical part and can be fixed in the axial direction by means of a holding device, an axial guide being effective between the reflector holder and the holding device. <IMAGE>
