Definitions

  • the invention relates to lighting devices, and more precisely those which comprise at least one source of photons and one lens participating in the production of a photometric function.
  • photometric function means both a lighting photometric function, a signaling photometric function or a light effect photometric function, possibly decorative.
  • lighting devices comprising a source generating photons and an elongated lens and acting on these photons so that they move towards a front part and participate in a chosen photometric function. It will be noted that such lighting devices can be part of an optical unit possibly performing at least one other photometric function.
  • the photometric function of the lighting device can, for example, be chosen from among a main beam function, a dipped beam (or low beam) function, and a fog lamp function. But it could also be a photometric signaling function.
  • FR2918040A1 describes a motor vehicle lighting or signaling device consisting of a transparent material inside which light diffusion focal points are located only at predetermined locations to diffuse the light emitted by at least one light source associated with the lighting or signaling device. These light sources can be of different colors.
  • this welcome light function may consist of operation of the turn signals or of the stop or position lights (or pilot light) for a few seconds.
  • the welcome light function does not use the main or dipped beam headlights, in particular because it is forbidden to use them in town and their electricity consumption is relatively high and therefore could discharge a very low battery charge.
  • the welcome light function must therefore be performed by a source other than that of the main beam or dipped beam function. It is recalled that currently it is prohibited by the regulations to have a single color reception source. It is in fact necessary that when the photometric measurements are taken, the color of the welcome light is drowned in the function of main beam or dipped beam, that is to say that the eye can see the welcome light color but that the optical measurement of this welcome light cannot be measured by the measuring device.
  • the object of the invention is therefore in particular to improve the situation.
  • a lighting device comprising a first source generating first photons defining a light of a first color, and a lens of elongated shape and acting on the first photons generated so that they move towards a part before and participate in a chosen photometric function.
  • the lighting of the lens by at least one of its ends, without using or disturbing the photometric function advantageously makes it possible to highlight the part of the lighting device which contributes to the style and/or to the signature, and therefore can allow at the same time to highlight the system which is equipped with this lighting device.
  • the invention also proposes a vehicle optical unit, optionally of the automotive type, and comprising at least one lighting device of the type presented above.
  • the invention also proposes a vehicle, optionally of the automobile type, and comprising at least one lighting device of the type of that presented above and/or at least one optical unit of the type of that presented above.
  • the object of the invention is in particular to propose a lighting device DE comprising a first source of photons S1 and a lens L participating together in a chosen photometric function, and at least one second source of photons S2 supplying at least one light guide Gj responsible for illuminating this lens L.
  • the lighting device DE is intended to equip an optical unit BO of a vehicle of the automobile type, such as for example a car.
  • a lighting device DE can be an item of equipment in itself (possibly comprising its own casing and its own protective glass), or it can be part of equipment other than a vehicle headlight unit.
  • a DE lighting device can be part of any vehicle (land, sea (or river), or air), any installation, including industrial type, any device ( or system), including consumer type, and any building.
  • the optical unit BO (comprising at least one lighting device DE) is a front projector (or headlight) ensuring at least one photometric function of lighting.
  • the lighting device DE is a lighting device capable of providing at least one photometric function of lighting or signaling or of lighting effect, possibly decorative, since this photometric function requires at least a photon source and a lens.
  • the X direction is a so-called longitudinal direction because it is intended to be parallel to a longitudinal side of a vehicle
  • the Y direction is a so-called transverse direction because it is intended to be perpendicular to the longitudinal sides of this vehicle and therefore perpendicular to the longitudinal direction X
  • the Z direction is a vertical direction, perpendicular to the longitudinal X and transverse Y directions.
  • a vehicle optical unit BO here a front headlight
  • a housing BB and a protective glass GP together delimiting a cavity housing a lighting device DE according to the invention.
  • the BB box is intended, here, to be secured to a part of the bodywork of a vehicle (here in a front part, such as for example a front wing). It is made of a rigid material, such as for example a plastic or synthetic material. In this case, it can be made by molding.
  • the protective glass GP can, for example, be made of glass or plastic. It (GP) is fixedly secured to a front part of the housing BB, for example by gluing, welding or screwing. Furthermore, it (GP) may optionally have one or more colors chosen from crystal white, red and orange.
  • a lighting device DE comprises a first source S1, a lens L, and at least one second source S2j associated with a light guide Gj.
  • the first source S1 is arranged so as to generate first photons which define a light of a first color (for example white).
  • This first source of photons S1 can, for example, comprise at least one light-emitting diode, of the conventional type (or LED (“Light-Emitting Diode”)) or of the organic type (or OLED (“Organic Light-Emitting Diode”)) , or a laser diode.
  • it (S1) comprises four groups of at least one light-emitting diode.
  • each group can comprise several (at least two) light-emitting diodes.
  • control means which can, for example, be part of at least one printed circuit board (not visible on the figure 2 ), possibly of the PCB (Printed Circuit Board) type. It will be noted that the first source of photons S1 can optionally also be installed on this printed circuit board.
  • Its main dimension (between its opposite ends E1j) extends along the transverse direction Y.
  • This lens L is arranged so as to act on the first photons generated by the first source S1 so that they move towards a front part and take part in a chosen photometric function.
  • This front part is located in front of the front face FV of the lens L, that is to say the face which is here placed facing the glass GP and through which the first photons on which the lens L acts emerge. In the example illustrated without limitation on the figure 1 , this front part is the GP glass.
  • this lens L can, for example, be made by molding (optionally by multilayer injection) of a transparent plastic material such as polymethyl methacrylate (or PMMA) or polycarbonate (or PC).
  • a transparent plastic material such as polymethyl methacrylate (or PMMA) or polycarbonate (or PC).
  • the lighting device DE comprises at least one second source S2j arranged so as to generate second photons which define light of a second color, preferably different from the first color.
  • this second color can be purple. It can, here, be characteristic of the model of the vehicle or of the make of the vehicle, or even be substantially identical to the (one) color of the bodywork of the vehicle, for example.
  • the (each) second source of photons S2j can, for example, comprise at least one light-emitting diode, of conventional type (or LED) or organic type (or OLED), or a laser diode.
  • the second source(s) of photons S2j can, for example, be installed on a support plate PS, as illustrated without limitation in the picture 2 .
  • This support plate PS can, for example, be a printed circuit board, possibly of the PCB type.
  • control means which can, for example, be part at least in part of at least one printed circuit board (not visible on the picture 2 ), possibly the same as that which controls the first source of photons S1.
  • the (each) second source S2j is associated with a light guide Gj which comprises first E21j and second E22j opposite ends, here along the longitudinal direction X.
  • the first end E21j is supplied with second photons generated by a second associated source S2j.
  • the second end E22j is placed close to one of the two opposite ends E1j of the lens L to supply it with second photons which have been guided from the first end E21j of its light guide Gj.
  • This power supply is intended to induce in at least part of the lens L internal lighting having the second color.
  • This internal lighting can constitute a welcome light which is generated to accommodate a user, here of the vehicle, who has been recognized near his vehicle, for example due to the fact that he is carrying communicating equipment authorized to dialogue at a short distance with this vehicle.
  • This equipment can, for example, be an electronic card or vehicle access key comprising near-field communication means, or an intelligent mobile telephone (or “smartphone”) comprising an application making it possible to control access to the vehicle.
  • a vehicle computer triggers the operation of each second photon source S2 for a short time (typically a few seconds), to welcome the user by means of a welcome light at the level of the lens L of each lighting device DE.
  • the lighting device DE comprises not one but two second sources S2j respectively associated with two light guides Gj.
  • the lighting device DE may only include a single second source S2j associated with a single light guide Gj.
  • each light guide Gj may comprise a beveled face in order to promote the internal reflection of the second photons in the direction of the end E1j of the lens L which is located nearby.
  • each second end face E22j can be beveled at approximately 45°. This option advantageously makes it possible to place each light guide Gj along one of the two lateral sides (j) of the lighting device DE, which promotes the compactness of the latter (DE) in the transverse direction Y.
  • each beveled face may comprise a coating or treatment on the side outside.
  • the lens L comprises two opposite outer faces Fk and extending between its opposite ends E1j
  • at least one of these outer faces Fk can comprise three-dimensional structures scattering some of the second photons outwards in order to induce a halo light effect.
  • the upper external face F1 1).
  • the two external faces Fk or even only the lower external face F2 can (Fri) t include three-dimensional structures, depending on the needs and the desired effect.
  • these three-dimensional structures can be grains defined by a sandblasting operation.
  • the lighting device DE can also comprise two side shields CLj each masking one of the opposite ends E1j of the lens L and at least a front part of the light guide Gj which comprises the second end E22j of the latter (Gj ), which supplies this end E1j of the lens L.
  • the first side cover CL1 masks the first end E11 of the lens L and at least a front part of the first light guide G1 (and in particular its second end E221), while the second side cover CL2 masks the second end E12 of the lens L.
  • the side covers CLj could fully mask the light guides Gj, and not just their front part.
  • These side covers CLj may optionally constitute stylized hubcaps.
  • these side covers CLj can be made by molding a rigid plastic or synthetic material, such as polyethylene (or PE) or polypropylene (or PP) or even polycarbonate (or PC), optionally treated (for example by metallization).
  • a rigid plastic or synthetic material such as polyethylene (or PE) or polypropylene (or PP) or even polycarbonate (or PC), optionally treated (for example by metallization).
  • the lighting device DE can also comprise a cover CS masking one of the two external faces Fk of the lens L (here the upper F1), the elements which take part in the photometric function and which are located upstream of the lens L, and a rear part of each light guide Gj comprising the first end E21j of the latter (Gj).
  • the cover CS comprises a central part extended on its two sides (j) by lateral wings masking the rear parts of the light guides Gj. This not only makes it possible to mask the elements which take part in the photometric function (apart from the front face FV of the lens L), but also the rear parts of the light guides Gj when they are not already masked by the side covers CLj.
  • the side wings of the cowl CS could mask all of the light guides Gj, in the absence of the side covers CLj.
  • this cover CS can be made by molding a rigid plastic or synthetic material, such as polyethylene (or PE) or polypropylene (or PP) or even polycarbonate (or PC).
  • a rigid plastic or synthetic material such as polyethylene (or PE) or polypropylene (or PP) or even polycarbonate (or PC).
