Description
Dispositif lumineux. Cette invention a pour objet un dispositif lumineux.
Selon l'invention, ce dispositif est caracté risé par au moins une plaque de verre péné trant par au moins un- de ses bords dans un boîtier opaque à éclairage intérieur et munie sur au moins un de ses bords visibles d'un chanfrein dépoli.
Le dispositif selon l'invention est destiné à être appliqué dans le domaine de la réclame, de la .décoration des immeubles ou de la si gnalisation, par exemple.
Le dessin schématique annexé représente trois formes d'exécution de l'invention, don nées à titre d'exemple.
Fig. 1 est une coupe parallèle à la plaque de la première forme d'exécution.
Fig. 2 en est la coupe transversale.
Fig. 3 est une vue de face de la deuxième forme d'exécution.
Fig. 4 en est la coupe transversale.
Fig. 5 est une vue de face de la troisième forme d'exécution dont la Fig. 6 est la coupe transversale. Les mêmes signes dans les six figures re- présentera les mêmes organes: Dans les fig. 1 et 2 une plaque .de verre a, présentant comme contour la silhouette d'une tête, pénètre par son bord inférieur dans la fente du boîtier opaque b, lequel ren ferme une rampe d'ampoules électriques c. Le contour de la plaque -de verre formant la silhouette présente un. chanfrein dépoli d.
Dans la forme d'exécution des fig. 3 et 4, la plaque de verre a est annulaire et pénètre par son bord intérieur dans le boîtier opaque b dans lequel est disposée l'ampoule électrique c qui s'engage dans l'ouverture centrale e de .la plaque. Cette ampoule distribue la lu mière dans toute la plaque, dont les bords ex- térieurs d sont chanfreinés sur tout le pour tour de la plaque, le chanfrein étant dépoli.
Dans cette forme d'exécution, la plaque pour rait être montée de façon à tourner par rap port au boîtier autour de l'axe de l'ouv'er- ture e.
Le dispositif représenté aux fig. 5 et 6 comporte trois plaques de verre a, de hauteurs différentes appliquées l'une sur l'autre et pé nétrant par leurs bords supérieurs dans le boîtier opaque b éclairé à l'intérieur par les lampes électriques c. Les bords inférieurs de ces plaques sont façonnés différemment et sont munis de chanfreins dépolis d. C'est. ainsi que les bords inférieurs de deux des plaques a sont ondulés et celui de la troisième plaque a taillé en ligne brisée.
Dans le but de produire des effets lumi neux donnant l'impression d'être animés, les différentes plaques de ce dernier dispositif pourraient aussi, au lieu d'être éclairées par une source de lumière commune, être éclairées chacune séparément. Cette disposition per mettra de les soumettre, une à une, à. un éclai rage successif correspondant aux phases suc cessives du mouvement à produire.
Luminous device. This invention relates to a light device.
According to the invention, this device is characterized by at least one glass plate penetrating by at least one of its edges into an opaque housing with interior lighting and provided on at least one of its visible edges with a frosted chamfer.
The device according to the invention is intended to be applied in the field of advertising, of the decoration of buildings or of signage, for example.
The attached schematic drawing shows three embodiments of the invention, given by way of example.
Fig. 1 is a section parallel to the plate of the first embodiment.
Fig. 2 is the cross section.
Fig. 3 is a front view of the second embodiment.
Fig. 4 is the cross section.
Fig. 5 is a front view of the third embodiment, of which FIG. 6 is the cross section. The same signs in the six figures will represent the same organs: In fig. 1 and 2 a glass plate a, having the outline of a head as its outline, penetrates by its lower edge into the slot of the opaque housing b, which closes a ramp of electric bulbs c. The outline of the glass plate forming the silhouette presents a. frosted chamfer d.
In the embodiment of FIGS. 3 and 4, the glass plate a is annular and penetrates through its inner edge into the opaque casing b in which the electric bulb c is arranged which engages in the central opening e of the plate. This bulb distributes the light throughout the plate, the outer edges of which are chamfered all around the plate, the chamfer being ground.
In this embodiment, the plate could be mounted so as to rotate relative to the housing about the axis of the opening e.
The device shown in FIGS. 5 and 6 comprises three glass plates a, of different heights applied one on top of the other and penetrating by their upper edges into the opaque housing b illuminated inside by the electric lamps c. The lower edges of these plates are shaped differently and have frosted chamfers d. This is. as well as the lower edges of two of the plates a are corrugated and that of the third plate a cut in a broken line.
In order to produce light effects giving the impression of being animated, the various plates of the latter device could also, instead of being illuminated by a common light source, each be illuminated separately. This will allow them to be submitted, one by one, to. a successive lighting corresponding to the successive phases of the movement to be produced.
