Abstract

The module has two light sources (14, 14) respectively arranged near focal points (F1, F1) of each of two elliptical reflectors (12, 12). The light source (14) is arranged in such a manner to emit a light beam only towards the elliptical reflector (12). The light source (14) is constituted of an encapsulated electroluminescent diode. The light sources are separated by an optical enclosure. An independent claim is also included for a headlight of a motor vehicle comprising a light module.
