This socket includes a number of axially extending external reinforcement ribs or otherwise thickened portions.，下面是Combination of a reflector and a halogen lamp专利的具体信息内容。
1. A combination of a reflector and a halogen lamp for exposing the film window of a film projector, the reflector which is manufactured from compressed glass comprising an ellipsoidal first part on the concave surface of which a reflecting layer is provided and a cylindrical socket part adjoining the first part and extending aloNg the optical axis of the reflector, said socket comprising a central channel with an elongate cross section having two approximately parallel long sides which opens into the ellipsoidal part, the light source being a halogen filament lamp having its pinch-shaped part secured in the said cylindrical part by means of a cement mass, characterized in that, calculated from the short axis of symmetry to throughout the long axis of symmetry of the said elongate cross section of the channel, the wall thickness of the transverse profile of the cylindrical reflector part increases to maximally double the wall thickness at the area of the short axis of symmetry.
2. A combination as claimed in claim 1, characterized in that the cylindrical reflector part is formed as a circular cylindrical surface having two external grooves extending axially in the reflecting axis, each groove extending beside the long sides of the channel and being formed as a part of a circular cylindrical concave surface.
