Abstract

A vehicle lighting device using a multiple-source optical lens is provided. The present invention relates to a part (7) made of transparent material, comprising at least two individual portions (16, 17, 18, 19, 20) each consisting of an input surface (21, 22, 23, 24, 25) and an output surface (26, 27, 28, 29 ,30), the output surface (26, 27, 28, 29 ,30) being focused on the input surface (21, 22, 23, 24, 25) of the same portion (16, 17, 18, 19, 20), the output surfaces (26, 27, 28, 29 ,30) being contiguous so as to form an overall output surface of the part (7) which is continuous. Furthermore, the input surfaces (21, 22, 23, 24, 25) are at a distance from one another by being separated by means (31, 32, 33, 34, 35, 36, 37, 38) suitable for preventing rays from a light source placed on the input surface (21, 22, 23, 24, 25) of a portion (16, 17, 18, 19, 20) from being able to pass through the output surface (26, 27, 28, 29 ,30) of the adjacent individual portion (16, 17, 18, 19, 20).

Description

technical field [0001] The invention relates to a vehicle lighting device using a multi-source optical lens. Background technique [0002] Lighting devices for installation in vehicle headlights are available and have been the subject of several patents. For example, patent application US 2007 / 0120137 may be cited, which relates to a multi-source lighting device comprising a plurality of independent and distinct components. Each assembly includes: a light source mounted on a substrate that supplies current to the light source; and a lens associated with the light source. All the light emitted by this light source is delivered to the output diopter of the lens via a duct whose cross-sectional area increases from said light source to said output diopter. The output diopter is D-shaped and may transmit the beam from the source in a single direction. The lighting device described in this document is therefore modular in that it can be composed of a variable number of individu...
