Abstract
The invention relates to a light module for a lighting device of a motor vehicle, including a light source and an optical device, the optical device being arranged to receive light emitted by the light source and to form, from the light, a light beam having an upper cut-off including a first portion and a second portion which are substantially horizontal and separated by a third portion descending from the first portion and ascending towards the second portion, the third portion being such that the light beam has, when projected onto a screen, a light-free zone extending at least horizontally in a range from substantially 0° to −2.2° and vertically in a range from substantially 0° to −0.8°.

A light-emitting module for a lighting device for a motor vehicle, comprising a light source and an optical device, the optical device being arranged to receive light emitted by the light source and to form, from this light, a light beam having an upper cutoff including a first segment and a second segment that are substantially horizontal and that are separated by a third segment that descends from the first segment and rises to the second segment, the third segment being such that the light beam has, when projected onto a screen, a zone devoid of light lying at least, horizontally, in a range extending substantially from 0° to −2.2° and, vertically, in a range extending substantially from 0° to −0.8°, when the light beam is projected onto the screen with a horizontal orientation of 0°, the optical device is arranged so that the third segment rises obliquely and substantially continuously from a point located horizontally between −3° and −4° and vertically between −1.7° and −2° to a point of junction with the second segment, the point of the junction with the second segment being located at 0°.
A lighting device for a motor vehicle, comprising:
- a light-emitting module, the light-emitting module including a light source and an optical device, the optical device being arranged to receive light emitted by the light source and to form, from this light, a light beam having an upper cutoff including a first segment and a second segment that are substantially horizontal and that are separated by a third segment that descends from the first segment and rises to the second segment in such a way as to form a substantially horizontal plateau positioned vertically at −0.8°, the third segment being such that the light beam has, when projected onto a screen, a zone devoid of light lying at least, horizontally, in a range extending substantially from 0° to −2.2° and, vertically, in a range extending substantially from 0° to −0.8°, with the light-emitting module being a first light-emitting module and the light beam formed by the optical device of this first light-emitting module being a first light beam, and
- a second light-emitting module including a light source and an optical device, the optical device of this second light-emitting module being arranged to receive light emitted by the light source of this second light-emitting module and to form, from this light, a second light beam having an upper cutoff, the first light-emitting module and the second light-emitting module being arranged so that the upper cutoffs of the first and second light beams are substantially at least partially aligned.
