Abstract (en)
[origin: EP1988330A1] The module (400) has a reflector comprising an internal surface formed by joining portions (207, 208) of respective ellipsoid molds, where the molds include respective main focal points (F11, F12, F21, F22). The focal point (F12) is engaged with the focal point (F21). The portion (208) reflects a part of light rays (S1-S3) emitted by a light source e.g. LED, and reflected by the portion (207) towards a projector lens (206). The light source is oriented in a direction opposite to an emission direction of a headlight device.
