Description
Domaine technique de l’inventionTechnical field of the invention
La présente invention concerne d'une manière générale le domaine des blocs optiques d'éclairage et/ou de signalisation pour véhicules automobiles. Elle concerne en particulier un bloc optique de signalisation de véhicule automobile comprenant une source lumineuse, un réflecteur pour réfléchir les rayons lumineux générés par la source lumineuse vers une face avant du bloc optique ainsi qu’un radiateur agencé en regard de la source lumineuse pour dissiper la chaleur produite par la source lumineuse. L’invention concerne également un véhicule automobile muni d’un tel bloc optique. L’invention s’applique, notamment, aux voitures.The present invention generally relates to the field of optical lighting and/or signaling units for motor vehicles. It relates in particular to a motor vehicle signaling optical unit comprising a light source, a reflector for reflecting the light rays generated by the light source towards a front face of the optical unit as well as a radiator arranged facing the light source to dissipate the heat produced by the light source. The invention also relates to a motor vehicle provided with such an optical unit. The invention applies, in particular, to cars.
État de la technique antérieureState of the prior art
On sait que les réglementations internationales imposent aux véhicules automobiles d’être pourvus à l’arrière de blocs optiques de signalisation afin de signaliser la position du véhicule aux autres usagers de la route. Un bloc optique de signalisation comporte classiquement au moins un boîtier destiné à être fixée sur la structure du véhicule et sur lequel est monté, directement ou par l'intermédiaire d'un support dédié, au moins un dispositif lumineux apte à assurer une fonction photométrique de signalisation comme par exemple un feu de recul, un feu STOP, un feu de brouillard arrière, etc.It is known that international regulations require motor vehicles to be provided at the rear with optical signaling units in order to signal the position of the vehicle to other road users. A signaling optical unit conventionally comprises at least one housing intended to be fixed to the structure of the vehicle and on which is mounted, directly or via a dedicated support, at least one light device capable of ensuring a photometric function of signaling such as a reversing light, a STOP light, a rear fog light, etc.
Chaque dispositif lumineux comprend classiquement au moins une source lumineuse constituée par une ampoule halogène à incandescence, et étant associée à un réflecteur apte à renvoyer les rayons lumineux lui parvenant en direction d’une face avant de sortie du bloc optique.Each light device conventionally comprises at least one light source constituted by an incandescent halogen bulb, and being associated with a reflector able to reflect the light rays reaching it in the direction of a front exit face of the optical block.
Or, chacun sait qu’une source lumineuse, en particulier une ampoule à incandescence, produit de la chaleur lorsqu’elle est allumée et, dans un bloc optique de signalisation de véhicule automobile, dont certains composants sont en matière plastique, la chaleur produite par l’ampoule engendre une usure prématurée du bloc optique et de l’ampoule.However, everyone knows that a light source, in particular an incandescent bulb, produces heat when it is lit and, in a motor vehicle signaling optical unit, some components of which are made of plastic, the heat produced by the bulb causes premature wear of the headlight unit and the bulb.
L’invention vise à pallier cet inconvénient. L’invention a en effet pour but de fournir une solution pour mieux dissiper la chaleur produite par une ampoule à incandescence agencée au sein d’un bloc optique de signalisation d’un véhicule automobile. Par ce biais, l’invention a pour dessein d’améliorer la durée de vie des blocs optiques de signalisation de véhicules automobiles et des ampoules utilisées au sein de ces blocs optiques.The invention aims to overcome this drawback. The object of the invention is in fact to provide a solution for better dissipating the heat produced by an incandescent bulb arranged within an optical signaling unit of a motor vehicle. In this way, the invention aims to improve the service life of the optical signaling units of motor vehicles and of the bulbs used within these optical units.
Ces buts sont atteints, selon un premier objet de l’invention, au moyen d’un bloc optique de signalisation de véhicule automobile comprenant une source lumineuse, un réflecteur pour réfléchir les rayons lumineux générés par la source lumineuse vers une face avant de sortie du bloc optique ainsi qu’un radiateur agencé en regard de la source lumineuse pour dissiper la chaleur produite par la source lumineuse, le radiateur ayant un profil en L et au moins un trou traversant.These objects are achieved, according to a first object of the invention, by means of an optical motor vehicle signaling unit comprising a light source, a reflector for reflecting the light rays generated by the light source towards a front exit face of the optical unit as well as a radiator arranged facing the light source to dissipate the heat produced by the light source, the radiator having an L-shaped profile and at least one through hole.
Selon une variante, le radiateur peut être fixé au bloc optique de sorte que le trou est au-dessus de la source lumineuse.Alternatively, the heatsink can be attached to the optical block so that the hole is above the light source.
Selon une autre variante, le radiateur peut comprendre six trous traversants.According to another variant, the radiator can comprise six through-holes.
Selon une autre variante, chacun des six trous peut être percé le long d’une courbe.Alternatively, each of the six holes can be drilled along a curve.
Selon une autre variante, chacun des six trous peut être percé sur une partie arrière du radiateur.According to another variant, each of the six holes can be drilled on a rear part of the radiator.
Selon une autre variante, le radiateur peut être fixé au bloc optique par une pluralité de cales.According to another variant, the radiator can be fixed to the optical unit by a plurality of wedges.
Selon une autre variante, le radiateur peut être en métal.According to another variant, the radiator can be made of metal.
Selon une autre variante, la source lumineuse peut consister en une ampoule à incandescence.According to another variant, the light source may consist of an incandescent bulb.
En outre, l’invention a également pour objet un véhicule automobile comprenant un bloc optique tel que décrit ci-dessus.In addition, the invention also relates to a motor vehicle comprising an optical unit as described above.
