Abstract

Lighting apparatus for a motor vehicle, such as a headlight or light for a motor vehicle, consisting of a casing closed by a glass (lens) and containing means for emitting light through the glass, the casing being provided with at least one ventilation duct, characterised in that the pipe (71) of the duct (7) includes an air deflector (baffle) (8).

Description

APPAREIL D'ECLAIRAGE POUR AUIDMIIEs
La présente invention se rapporte à un appareil d'éclairage tel que phare ou feu pour automobiles, constitué d'un boîtier fermé par une glace et contenant des moyens d'émission de la lumière au travers de la glace, ce boîtier étant pourvu d'au moins un évent d'aération
A l'intérieur des phares d'éclairage, l'eau a tendance à se condenser ce qui perturbe l'éclairage ou le bon fonctionnement.LIGHTING APPARATUS FOR AUIDMIIES
The present invention relates to a lighting device such as a headlight or a light for automobiles, consisting of a housing closed by a glass and containing means for emitting light through the glass, this housing being provided with at least one ventilation vent
Inside the lighting headlights, the water tends to condense which disturbs the lighting or the proper functioning.

L'eau peut pénétrer dans les phares en phase liquide par écoulement, suintement, aérosol ou brouillard ou en phase vapeur.Water can enter the headlights in the liquid phase by flow, seepage, aerosol or mist or in the vapor phase.

L'entrée d'eau peut être contrariée en améliorant l'étanchéité mais cette solution induit des difficultés constructives.The water inlet can be thwarted by improving the seal, but this solution causes constructive difficulties.

Les boîtiers de phares sont souvent pourvus, à l'arrière d'évents d'aération permettant la ventilation de l'intérieur.The headlight boxes are often provided, at the rear with ventilation vents allowing ventilation from the inside.

On a envisagé dans le FR-A-2.225.689 de monter sur le boîtier de phare un filtre assurant l'aération mais arrêtant l'eau. Cette solution ne s'est pas révélée efficace.It has been envisaged in FR-A-2,225,689 to mount on the headlight housing a filter ensuring ventilation but stopping the water. This solution has not proven to be effective.

La présente invention a pour but de fournir un appareil d'éclairage protégé contre les entrées d'eau. The object of the present invention is to provide a lighting device protected against ingress of water.

Conformément à l'invention, l'appareil d'éclairage est caractérisé par le fait que le conduit de l'évent comporte un déflecteur d'air.According to the invention, the lighting apparatus is characterized in that the vent duct includes an air deflector.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation donné à titre d'exemple et représente par les dessins annexés sur lesquels: - la figure 1 est une vue en coupe d'un appareil d'éclairage selon l'invention.The invention will now be described in more detail with reference to an embodiment given by way of example and represented by the accompanying drawings in which: - Figure 1 is a sectional view of a lighting fixture according to the invention.

- la figure 2 est une vue de détail d'un composant de l'appareil d'éclairage de la figure 1.- Figure 2 is a detailed view of a component of the lighting apparatus of Figure 1.

Le phare représenté à la figure 1 comporte une glace diffusante I fixée à l'avant d'un boîtier fixe (2) à l'intérieur duquel est logé un réflecteur 3 servant à réfléchir vers la glace la lumière venant d'une ampoule électrique 4. Cette ampoule 4 est montée sur un culot amovible 5 se fixant sur une douille du boîtier.The headlight shown in Figure 1 has a diffusing glass I attached to the front of a fixed housing (2) inside which is housed a reflector 3 used to reflect towards the glass the light coming from a light bulb 4 This bulb 4 is mounted on a removable base 5 which attaches to a socket of the housing.

Le boîtier comporte à l'arrière un évent 31 en partie haute et un évent 32 en partie basse. Le tube d'évent 31 porte un tube 6 dont l'extrémité est emmanchée sur un embout tubulaire de l'évent. De même l'évent 32 porte un tube 7 dont l'extrémité est emmanchée sur l'embout tubulaire de l'évent.The housing has at the rear a vent 31 at the top and a vent 32 at the bottom. The vent tube 31 carries a tube 6, the end of which is fitted onto a tubular end piece of the vent. Likewise, the vent 32 carries a tube 7, the end of which is fitted onto the tubular end piece of the vent.

Les deux tubes 6 et 7 sont recourbés vers le bas de manière à permettre l'écoulement de l'eau. The two tubes 6 and 7 are bent downwards so as to allow the water to flow.

Dans le conduit 71 du tube 7 de l'évent inférieur se loge un déflecteur d'air 8 faisant office de barrière ou de piège à aérosol. Ce déflecteur n'obstrue que partiellement la section du conduit. Dans le mode de réalisation représenté, ce déflecteur est constitué par un ruban enroulé en hélice.In the duct 71 of the tube 7 of the lower vent is housed an air deflector 8 acting as a barrier or an aerosol trap. This deflector only partially obstructs the section of the duct. In the embodiment shown, this deflector is constituted by a ribbon wound in a helix.

Ce déflecteur représenté par la figure 2 peut être réalisé en matière plastique. En variante ce déflecteur pourrait être constitué par un caillebotis ou toute autre pièce de grande surface imposant une grande longueur trajet à l'air entre l'intérieur de l'appareil d'éclairage et l'extérieur.This deflector shown in Figure 2 can be made of plastic. As a variant, this deflector could be constituted by a grating or any other large surface part imposing a long path in the air between the interior of the lighting fixture and the exterior.

Le fonctionnement est le suivant:
Lorsque l'air humide entre par le conduit 71 le déflecteur 8 fait une barrière sur laquuelle se dépose l'eau sous phase liquide en suspension dans l'air. Le dessin du déflecteur est tel que l'eau déposée puisse s'écouler vers l'extérieur. The operation is as follows:
When the moist air enters through the conduit 71 the deflector 8 forms a barrier on which the water is deposited in the liquid phase in suspension in the air. The design of the deflector is such that the deposited water can flow outwards.
