Abstract
A headlamp for an automobile vehicle comprises a luminous filament, a reflector, and a closing glass. According to the invention, the reflector comprises a parabolic base part and side pieces in the form of parabolic cylinders focussed on the filament, and in addition there are deflecting means, for example toroidal lenses, which re-direct the inclined rays of light received from the filament into the horizontal direction, towards the side pieces. A greater proportion of the luminous flux is thus recovered, which enables production of lamps with a small height and with a high efficiency.
