Abstract
An electric light source for use in a vehicle headlight unit capable of emitting dipped light beams, especially a sealed-beam headlight unit. The light source has a single filament or two-filament halogen lamp and an inner or outer screen element preventing the incidence of light from the dipping filament on the reflector. The shape of the rim of the screen element is a specially developed three-dimensional curve, whereby a distribution of the projected light is achieved which does not blind the drivers of oncoming vehicles. The shape of the three-dimensional curve forming the rim of the screen element can be determined point-by-point from the light distribution required, taking into consideration prescribed geometrical interrelations.
