Abstract

Public illumination instrument of the type comprising a reflector closed by a transparent and/or translucent member, characterised in that the reflector 1 and the said member 2 are sealed together, in an inseparable manner, this assembly comprising an orifice, normally closed by a leaktight stopper 3 allowing the introduction of the light source 6. The stopper is fixed to a base 4 which is solidly attached to the optical system and comprises the adjustment device 7 for the light source, a wire passage 11 for the supply cable and a breathing filter 10.

Description

La présente invention concerne des perfectionnements aux appareils d'éclairage public. The present invention relates to improvements to public lighting apparatus.

On sait que ces appareils se composent d'un réflecteur, éventuellement logé dans un capot protecteur,dont l'ouverture inférieure est obturée par une vasque, transparente et,ou, translucide, ou par une vitre, la source lumineuse étant logée à l'intérieur. We know that these devices consist of a reflector, possibly housed in a protective cover, the lower opening of which is closed by a basin, transparent and / or translucent, or by a window, the light source being housed in the interior.

L'étanchéité entre le réflecteur et la vasque ou le corps et la vasque est assurée par un joint périphérique. The seal between the reflector and the bowl or the body and the bowl is ensured by a peripheral seal.

L'accès à la source lumineuse s'effectue par l'ouverture de la vasque. Access to the light source is via the opening of the basin.

Ces appareils présentent des inconvénients importants qu'il est bon de rappeler ci-dessous. These devices have significant drawbacks which are worth recalling below.

Le dispositif peut présenter initialement des défauts d'étanchéité résultant,soit d'un mauvais positionnement du joint périphérique,soit d'une défectuosité des surfaces d'appui (erreur de planéité). The device may initially have leaks resulting from either a poor positioning of the peripheral seal, or a defect in the bearing surfaces (flatness error).

Ces défauts peuvent aussi apparaître lors de l'ouverture ou de la fermeture de la vasque pour accéder au réflecteur et à la source lumineuse. These faults can also appear when opening or closing the bowl to access the reflector and the light source.

Un tel défaut d'étanchéité se traduit par un encrassement interne de l'enceinte optique entraînant une baisse des performances lumineuses de l'appareil. Such leakage results in internal fouling of the optical enclosure resulting in a decrease in the light performance of the device.

La présente invention, qui remédie à ces inconvénients,est remarquable en ce que le réflecteur et l'organe transparent et ou translucide l'obturant,sont scellés l'un à l'autre de façon indissociable,cet ensemble comportant un orifice,normalement obturé par un bouchon étanche permettant d'introduire et de maintenir la source lumineuse. The present invention, which overcomes these drawbacks, is remarkable in that the reflector and the transparent and / or translucent shutter, are sealed to each other inseparably, this assembly comprising an orifice, normally closed. by a watertight plug allowing to introduce and maintain the light source.

D'autres caractéristiques ressortiront mieux de la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement,sur lequel:
La figure 1 est une vue en coupe d'un appareil d'éclairage public, conforme à l'invention
La figure 2 est une vue analogue à la figure 1 montrant un autre mode de réalisation d'un appareil d'éclairage du type "projecteur".
Other characteristics will emerge better from the description which follows, made with reference to the attached drawing by way of indicative example only, in which:
Figure 1 is a sectional view of a public lighting device, according to the invention
Figure 2 is a view similar to Figure 1 showing another embodiment of a lighting fixture of the "projector" type.

En se reportant au dessin et selon un mode de réalisation,on voit que le système optique est constitué par un réflecteur 1, obturé par une vasque 2 transparente et,ou,translucide.  Referring to the drawing and according to one embodiment, it can be seen that the optical system consists of a reflector 1, closed by a transparent and, or, translucent bowl 2.

Selon l'invention, le réflecteur 1 et la vasque 2 sont scellés l'un à l'autre de façon indissociable,par tous moyens usuels. According to the invention, the reflector 1 and the basin 2 are sealed to each other inseparably, by any usual means.

Le réflecteur 1 présente une ouverture, normalement obturée par un bouchon 3 se fixant sur une embase 4 rendue solidaire dudit réflecteur. The reflector 1 has an opening, normally closed by a plug 3 which is fixed to a base 4 made integral with said reflector.

Le diamètre intérieur de l'embase est prévu pour permettre le passage de la douille 5 de support de la lampe 6. The internal diameter of the base is provided to allow the passage of the lamp support socket 5 6.

Le bouchon 3 supporte la douille 5 par l'entremise de son dispositif de réglage en position 7 auquel on accède par une ouverture 8 dudit bouchon,normalement obturé par une trappe 9 amovible. The plug 3 supports the sleeve 5 by means of its adjustment device in position 7 which is accessed by an opening 8 of said plug, normally closed by a removable hatch 9.

Le bouchon 3 supporte également un filtre de respiration 10 et le passe-fils 11 permettant l'introduction des câbles électriques d'alimentation.Le filtre de respiration au charbon actif, évite à l'enceinte optique de fonctionner en surpression ou en dépression lors de l'allumage-ou de l'extinction de la lampe. The plug 3 also supports a breathing filter 10 and the grommet 11 allowing the introduction of the electric power cables. The breathing filter with activated carbon prevents the optical enclosure from operating under overpressure or under depression during switching the lamp on or off.

La figure 2 montre un second mode de réalisation,concernant un appareil d'éclairage comportant un capot protecteur 12 dans lequel est logé le réflecteur 13,l'ensemble étant obturé par une vitre 14. Selon l'invention, la périphérie de la vitre 14 est scellée, de façon indissociable, sur le capot 12. FIG. 2 shows a second embodiment, relating to a lighting device comprising a protective cover 12 in which the reflector 13 is housed, the assembly being closed by a window 14. According to the invention, the periphery of the window 14 is sealed, inseparably, on the cover 12.

Le réflecteur présente-une ouverture 15 de passage de la douille 5 et l'embase 4 est fixée sur le capot. The reflector has an opening 15 for passage of the socket 5 and the base 4 is fixed to the cover.

Sur le dessin, la fixation du bouchon 3 s'effectue par ltentremise d'un dispositif à baïonnette-,mais tous autres moyens peuvent être utilisés. In the drawing, the plug 3 is fixed by means of a bayonet device, but any other means can be used.

I1 ressort de la description ci-dessus que la qualité de l'étanchéité du système optique dépend uniquement du procédé utilisé pour réaliser le scellement et que cette qualité ne peut pas être altérée lors des interventions d'entretien qui,d'ailleurs, se limitent pratiquement au changement de la lampe puisque les agents polluants ne peuvent pas pénétrer dans le système optique. I1 emerges from the above description that the quality of the sealing of the optical system depends only on the process used to perform the sealing and that this quality can not be altered during maintenance interventions which, moreover, are limited practically when the lamp is changed since pollutants cannot penetrate the optical system.

La seule pénétration possible des agents polluants s'effectue au niveau de la liaison embase-bouchon mais dans ce cas et comme la section est considérablement réduite par rapport aux systèmes traditionnels,il est très facile de s'y opposer par l'utilisation d'un joint approprié.  The only possible penetration of pollutants is at the base-plug connection but in this case and as the section is considerably reduced compared to traditional systems, it is very easy to oppose it by the use of an appropriate seal.
