In fact, the color of the incoming light is drowned out in the high beam or low beam function during the photometric measurement, that is to say the color of the incoming light is seen by the eyes, but the optical measurement of this incoming light is not possible with the measuring device take measurements

Embodiment Construction

[0029] In particular, the invention aims at proposing an illumination device DE comprising: a first photon source S1 and a lens L which together participate in a selected photometric function; and at least one second photon source S2 which At least one light guide Gj responsible for illuminating the lens L is supplied.

[0030] In the following, as a non-limiting example, it is considered that the lighting device DE is used to equip an optical unit BO of a vehicle of motor vehicle type, eg an automobile. However, the invention is not limited to this application. In fact, the lighting device DE may be a piece of equipment itself (it may include its own housing as well as its own protective window), or it may belong to another piece of equipment of the vehicle's optical unit. Therefore, the lighting device DE may be part of any vehicle (land vehicle, sea (or river) vehicle or flight vehicle), part of any device including industrial type devices, any instrument (or system) inclu...

Abstract

A lighting device (DE) comprises: - a first source (S1) generating first photons defining a light of a first color, - a lens (L) of elongated shape and acting on the first photons generated so that they go towards a front part and participate in a chosen photometric function, - at least a second source (S21) generating second photons defining light of a second color, and - at least one light guide(G1) comprising a first end (E211) supplied with second photons generated, a second end (E221) placed in the vicinity of one of two opposite ends (E11) of the lens (L) to supply it with second guidedphotons, in order to induce in at least part of the lens (L) an internal light having the second color.

Description

technical field [0001] The present invention relates to lighting devices, and more particularly to lighting devices comprising at least one photon source and a lens participating in the photometric function. Background technique [0002] In the following, a "photometric function" is to be understood as being either a lighting photometric function, a signal photometric function or possibly a decorative light effect photometric function. [0003] In some fields, for example the field of vehicles, possibly of the motor vehicle type, lighting devices are used which comprise a source generating photons and a lens of elongated shape which acts on these photons to direct them towards the front part. photons and engage those photons in selected photometric functions. It should be noted that such lighting means may be part of an optical unit possibly ensuring at least one other photometric function. [0004] In the case of a vehicle, the photometric function of the lighting device ...
