Abstract

The integrated transformer-lamp unit is fitted in the head of a lamp. The lamp head has a shell (5) housing the transformer-lamp unit and carrying a shade (7). The power supply cable (4) enters the rear of the shell. The transformer is housed in a cylindrical box (1) that fits inside the lamp head. The end of the cylindrical box has a fitting (9) to accept the base of the lamp bulb (8). Connections from the transformer secondary to the lamp socket are enclosed in the cylindrical box. The lamp bulb is of the reflective type.

Description

La présente invention concerne un produit constitué d'un ensemble transformateur / Projecteur encastrable pour lampe d'éclairage à très basse tension. The present invention relates to a product consisting of a transformer / recessed projector assembly for a very low voltage lighting lamp.

Antérieurement l'installation d'un projecteur encastrable pour lampe d'éclairage à très basse tension, nécessitait de procéder à la pose d'un transformateur réduisant la tension d'alimentation et d'assurer ensuite la liaison électrique par cable entre le transformateur et le projecteur suivant une distance de séparation minimale de 0,50 m afin d' éliminer les risques dûs aux échauffements. Previously, the installation of a built-in projector for a very low voltage lighting lamp required the installation of a transformer reducing the supply voltage and then ensuring the electrical connection by cable between the transformer and the headlamp following a minimum separation distance of 0.50 m in order to eliminate the risks due to overheating.

Le produit selon l'invention permet de regrouper en un seul ensemble le transformateur et le projecteur. The product according to the invention makes it possible to group the transformer and the projector in a single assembly.

Celui ci comporte un boitier supérieur (1) dans lequel s'intégre un transformateur de puissance adapté (2) et noyé dans une résine (3). This one includes an upper box (1) in which is integrated a suitable power transformer (2) and embedded in a resin (3).

La liaison extérieure au réseau d'alimentation est assurée par un cable éléctrique (4) à 2 conducteurs, résistant à une température d'au moins 1700 -C. The external connection to the supply network is ensured by an electric cable (4) with 2 conductors, resistant to a temperature of at least 1700 -C.

est accouplé au boitier supérieur, la partie projecteur (5) qui fait aussi office de support de lampe (8) - un ressort de sécurité (6) assure 1' anti-chute de la lampe. is coupled to the upper housing, the projector part (5) which also acts as a lamp holder (8) - a safety spring (6) ensures one fall of the lamp.

La partie inférieure du projecteur sert de collerette d'arrêt lors de l'encastrement. L'ensemble transformateur / projecteur est maintenu en position après encastrement par 2 ressorts (7)
La lampe lors de son montage est accouplée sur une douille (9) qui est reliée au transformateur par une liaison électrique souple(10).The lower part of the headlamp serves as a stop flange during installation. The transformer / projector assembly is held in position after installation by 2 springs (7)
The lamp during its assembly is coupled to a socket (9) which is connected to the transformer by a flexible electrical connection (10).

A titre d'exemple non limitatif l'ensemble transformateur / projecteur tel que représenté sur la figure 1, est destiné à favoriser l'installation des éclairages à très basse tension, comportant une lampe halogène à réflecteur dichroique. il est de ce fait particuliérement étudié pour résister à des températures de contraintes élevées, supérieures à plus de 1500C généré par ce type de lampe. By way of nonlimiting example, the transformer / projector assembly as shown in FIG. 1 is intended to favor the installation of very low voltage lighting, comprising a halogen lamp with dichroic reflector. it is therefore particularly studied to withstand high stress temperatures, higher than more than 1500C generated by this type of lamp.

La construction de 1' ensemble est prévue pour ne pas propager la flamme en cas d'incendie. Résistance au fil incandescent à + 8500-C suivant norme EN 60742 article 26. (édition Juillet 1989). The construction of the assembly is designed not to propagate the flame in the event of a fire. Resistance to glowing wire at + 8500-C according to standard EN 60742 article 26. (July 1989 edition).

Une variante non représentée permet de prévoir une orientation de la partie projecteur / support de la lampe pour assurer un angle de balayage de 1800- par rapport au plan d'encastrement de l'ensemble transformateur / projecteur.  A variant not shown makes it possible to provide an orientation of the projector / lamp support part to ensure a scanning angle of 1800- relative to the mounting plane of the transformer / projector assembly.
