ABSTRACT:
A luminaire for an electric lamp in which the two parts of a bipartite housing having a double-hinge are connected together comprises according to the invention a stop by which the possibility of rotation around a shaft of the double hinge is restricted. In spite of an overlap of one part of the housing by the other part of the housing, the housing is opened and closed thereby in a quasi-single rotating movement.
In a special embodiment means are present near the main point of rotation so as to space the two parts of the housing from each other upon opening same.
