Abstract
The sections of the filament of a projection lamp are stretched over two sets of supports anchored in glass beams which are fixed on the rigid current supply conductors to form a frame. The supports each consist of a wire having a hooked end which engages the filament between a respective pair of adjacent sections. The supports of at least one set each have an end portion extending transverse to the main link of the support. Each end portion is located at the same given distance from the bend of the hook, and preferably extends from a free end of the hook. This permits each section to be under the same tension.
