Description
Dispositif d'éclairage. La présente invention a pour objet un dispositif d'éclaira:ge, qui est caractérisé en ce qu'il :comporte une enveloppe présentant une ouverture et, dans cette enveloppe, au moins une source lumineuse et des moyens mobiles capables d'occuper plusieurs posi tions dans chacune desquelles ils ,déterminent l'émission à travers l'ouverture susdite, de lumière d'une certaine couleur différente d'une position à l'autre de ces moyens.
Le dessin annexé représente, à titre d'exemples, deux formes :d'exécution du dis positif selon S'invention.
La fig. 1 représente une vue :de face, par tie en :coupe, de la première forme d'exécu tion.
Fig. 2 est une vue en coupe horizontale correspondant à la fig. 1.
Fig. 3 est une vue analogue à la fig. ?, mais relative à la seconde forme d'exécution. Le dispositif représenté sur les fig. 1 et 2 rst destiné, par exemple, à l'éclairage d'un objet, 4'un décor, d'une paroi, d'un motif sculpté ou d'un bas-re@lie±, représenté schéma tiquement en 1. Le dispositif comporte une enveloppe 2, de forme cylindrique, présen tant une ouverture. longitudinale 3.
Le dis positif :comporte en outre, :dans cette enve loppe, une source qumineuse 4 représentée ici sous la forme d'un tube à décharge lumi neuse, s'étendant axialeiment à l'intérieur de l'enveloppe 2, à peu près sur toute la lon gueur de celle-ci.
Il s'agit d'une source de lumière blanche, Le dispositif comporte en- cors, également à l'intérieur de l'enveloppe 2, unr- série d'écrans transparents 5, 6, 7, 8, 9 et 10, disposés côte à côte pour former en semble un cylindre concentrique avec l'enve loppe 2. Chacune des parties 5, 6, 7, 8, 9 et 10 s'étend sur à peu près toute la hauteur intérieure de l'enveloppe 2 et, dans. le sens périphérique, sur un angle de 60 . Ces, six parties sont de six couleurs différentes.
Ces six parties 5 à 10 sont portées par un sup port l'1 pivotant en 12 dans la base de l'en veloppe 2. Ce support 11 :est solidaire d'une roue dentée 18, entraînée par un moteur non représenté, par l'intermédiaire d'un pi gnon 14.
L'ouverture à s'étend dans le sens péri phérique sur un angle de moine de 6-0 et elle est disposée de telle façon que la lumière émanant de la source 4 et passant à travers cette ouverture arrive sur l"objet 1. On voit immédiatement qu'au cours <B> & -</B> la rotation de la roue dentée 113, les différentes parties transparentes colorées 5, 6, 7, 8, 9, 10 passent successivement en regard de l'ouverture 3 et sont successivement traversées par les rayons émanant de la source 4 et arrivant sur l'objet 1.
L'objet 1 sera donc éclairé suc- ceissivement par des lumières de couleurs différentes. On peut ainsi obtenir, selon la nature -de l'objet 1, des, effets artistiques assez agréables à l'oeil.
Dans le cas;,de la fig. 31, le dispositif com porte, comme dans le premier cas, une enve loppe 2, ayant la môme forme que dans l'exemple précédemment décrit. L'objet l; joue le même râle que dans le premier exemple. A l'intérieur de l'enveloppe 2 est disposé un support tournant 15, monte pour tourner au tour de l'axe géométrique @de l'enveloppe 2.
Ce support porte quatre sources lumineuses 116, 17, 1-8, 19 s'étendant chacune suivant une direction parallèle .à l'axe de Vènveloppe 2 et qui sont équidistantes de l'axe -géométrique de cette enveloppe, comme on le voit sur la fig. 3.
Les -quatre sources 1,6, 17, 18, 19 donnent ,chacune une lumière de couleur dif férente et il est prévu des moyens grâce aux quels seule celle de ces quatre sources -qui se trouve en regard .de l'ouverture 3 soit reliée à une source de courant, en sorte que seule cette source (soit 19, pour la position repré sentée sur de dessin) serve à éclairer l'écran.
Le support 15 peut soit être entraîné -de façon continue, comme il a été indiqué dans l'exemple suivant fig. 1 et 2, pour le support 11, -soit être commandé à 1-a main, pour ame ner à volonté en face de l'ouverture 3 lu source donnant la lumière de couleur désirée. Pour augmenter l'intensité de la lumière pro jetée sur l'objet 1, on prévoira avantageuse ment que la surface intérieure de -l'enveloppe 2 soit réfléchissante.
Lighting device. The present invention relates to a lighting device: ge, which is characterized in that it: comprises an envelope having an opening and, in this envelope, at least one light source and mobile means capable of occupying several positions. tions in each of which they determine the emission through the aforementioned opening of light of a certain color different from one position to another of these means.
The appended drawing represents, by way of examples, two forms: execution of the positive device according to the invention.
Fig. 1 shows a view: from the front, partly in: section, of the first embodiment.
Fig. 2 is a horizontal sectional view corresponding to FIG. 1.
Fig. 3 is a view similar to FIG. ?, but relating to the second embodiment. The device shown in FIGS. 1 and 2 rst intended, for example, for the lighting of an object, 4 'a decoration, a wall, a sculpted motif or a bas-re @ lie ±, represented diagrammatically in 1. The device comprises a casing 2, of cylindrical shape, having an opening. longitudinal 3.
The positive dis: further comprises: in this casing, a quminous source 4 shown here in the form of a lumi nous discharge tube, extending axially inside the casing 2, approximately over the whole length of it.
This is a source of white light. The device comprises incors, also inside the casing 2, a series of transparent screens 5, 6, 7, 8, 9 and 10, arranged side by side to form a seemingly concentric cylinder with the casing 2. Each of the parts 5, 6, 7, 8, 9 and 10 extends over almost the entire interior height of the casing 2 and, in . the peripheral direction, on an angle of 60. These, six parts are six different colors.
These six parts 5 to 10 are carried by a support 1'1 pivoting at 12 in the base of the envelope 2. This support 11: is integral with a toothed wheel 18, driven by a motor not shown, by the 'intermediary of a pi gnon 14.
The opening to extends in the peripherical direction on a monk angle of 6-0 and it is arranged so that the light emanating from the source 4 and passing through this opening arrives on the object 1. On immediately sees that during <B> & - </B> the rotation of the toothed wheel 113, the different colored transparent parts 5, 6, 7, 8, 9, 10 pass successively opposite the opening 3 and are successively crossed by the rays emanating from the source 4 and arriving on the object 1.
Object 1 will therefore be illuminated successively by lights of different colors. It is thus possible to obtain, depending on the nature of the object 1, artistic effects which are quite pleasing to the eye.
In the case;, of FIG. 31, the device com door, as in the first case, an envelope 2, having the same shape as in the example described above. The object l; plays the same groan as in the first example. Inside the envelope 2 is arranged a rotating support 15, mounted to rotate around the geometric axis @of the envelope 2.
This support carries four light sources 116, 17, 1-8, 19 each extending in a direction parallel to the axis of the envelope 2 and which are equidistant from the -geometric axis of this envelope, as seen on fig. 3.
The -four sources 1,6, 17, 18, 19 each give light of a different color and means are provided by which only that of these four sources -which is located opposite the opening 3 is connected to a current source, so that only this source (ie 19, for the position shown in the drawing) is used to illuminate the screen.
The support 15 can either be driven continuously, as indicated in the following example fig. 1 and 2, for the support 11, -or be controlled 1-a hand, to ame ner at will in front of the opening 3 lu source giving the desired color light. To increase the intensity of the light projected onto the object 1, provision will advantageously be made for the interior surface of the envelope 2 to be reflective.
