Abstract

The invention relates to a means of increasing the visibility of an object without using supplementary light energy by using the phenomenon of simultaneous contrast and of successive contrast, in an appropriate way. To this end, the object is covered with several regions coloured alternately with any complementary colours. A rotational or translational movement brings the contrast into play and the object appears to be illuminated if the colours are bright. Thus a rotating alarm light is produced, without a light source, or a very visible advertising poster.

Description

La présente invention est relative à un moyen d'augmenter la luminosité d'un objet sans avoir à lui fournir un supplément d'énergie lumineuse. Elle concerne les utilisations, adaptées à cette fin, du phénomène de contraste successif.The present invention relates to a means of increasing the brightness of an object without having to provide it with additional light energy. It relates to the uses, adapted for this purpose, of the phenomenon of successive contrast.

Ce phénomène réside dans le fait qu'en disparaissant, la couleur d'une plage lumineuse fait apparement place pour l'oeil, à sa couleur complémentaire. Les couleurs complémentaires sont celles qui superposées sur un écran blanc donnent du blanc, par exemple le rose et le vert, le bleu et le jaune, et tout ensemble de deux couleurs représentées sur le triangle des couleurs par deux points alignés avec le centre de gravité du dit triangle.This phenomenon resides in the fact that by disappearing, the color of a light area apparently makes room for the eye, to its complementary color. Complementary colors are those superimposed on a white screen give white, for example pink and green, blue and yellow, and any set of two colors represented on the color triangle by two points aligned with the center of gravity of the said triangle.

Le phénomène est d'autant plus intense que les plages colorées sont plus lumineuses et on n'enlève ni ajoute rien à l'invention en éclairant vivement ces plages qui subissent ensuite une augmentation de luminosité sans apport d'énergie lumineuse supplémentaire.The phenomenon is all the more intense as the colored areas are brighter and nothing is removed or added to the invention by brightly illuminating these areas which then undergo an increase in brightness without additional light energy.

L'invention consiste à faire se succéder sur l'objet à rendre plus lumineux deux couleurs complémentaires afin de réaliser l'idée suivante qui est celle de l'invention : si on fait en sorte que lorsqu'une couleur disparait la couleur complémentaire de celle qui disparait prenne sa place, comme de toute façon l'oeil voit déjà à cette même place une couleur fictive complémentaire de celle qui disparait, la superposition à la couleur réelle, de la couleur fic tive de même teinte, donnera une plage dont la luminosité sera ren forcée par rapport à ce qu'elle serait sous la seule vision de la plage réelle et celà sans qu'on ait fourni un supplément d'énergie lumineuse.The invention consists in making a succession of two complementary colors on the object to make it brighter in order to realize the following idea which is that of the invention: if we make sure that when a color disappears the complementary color which disappears takes its place, as in any case the eye already sees in this same place a fictitious color complementary to that which disappears, the superposition on the real color, of the fictitious color of the same shade, will give a range whose luminosity will be renforced compared to what it would be under the only vision of the real range and that without having provided an additional light energy.

L'invention consiste aussi simultanément dans l'utilisation de cette méthode pour réaliser des systèmes d'alarme visuelle ou des images publiscitaires attrayantes et attirantes pour le regard.The invention also consists simultaneously in the use of this method for producing visual alarm systems or advertising images that are attractive and attractive to the eye.

Voici maintenant comment on peut s'y prendre pour réaliser l'invention.Here is how we can go about making the invention.

Qu'il s'agisse de réaliser un système d'alarme ou une image publiscitaire les dimensions recommandées ici peuvent varier dans d'importantes proportions notamment pour tenir compte dfe la persistance des impressions lumineuses sur la rétine de l'oeil.Whether it's an alarm system or a publicity image the dimensions recommended here can vary in important proportions in particular to take account of the persistence of the luminous impressions on the retina of the eye.

L'axe d'un cylindre de vingt centimètres de diamètre et vingt centimètres de hauteur est matérialisé pour qu'on puisse faire tourner le cylindre. Sur la surface latérale de ce cylindre on dispose des plages roses et des plages vertes claires de préférence fluorescentes pour que le phénomène soit le plus intense possible. La disposition des plages sur la surface latérale se fait sur trois parties délimitées par les bords du cylindre et par deux circonférences parallèles à ces bords de façon à former une zone médiane de quinze centimètres de largeur et deux zones latérales adjacentes à la zone médiane, de largeurs égales chacune à deux centimètres et demi.The axis of a cylinder twenty centimeters in diameter and twenty centimeters in height is materialized so that we can rotate the cylinder. On the lateral surface of this cylinder there are pink areas and light green areas, preferably fluorescent so that the phenomenon is as intense as possible. The arrangement of the pads on the lateral surface is made on three parts delimited by the edges of the cylinder and by two circumferences parallel to these edges so as to form a median zone of fifteen centimeters in width and two lateral zones adjacent to the median zone, of widths each equal to two and a half centimeters.

La zone médiane est divisée en quatre parties par des sections de droites parallèles à l'axe du cylindre. Ces quatre parties sont colorées alternativement dans le sens de la rotation autour de l'axe du cylindre les unes en rose les autres en vert.The middle zone is divided into four parts by sections of straight lines parallel to the axis of the cylinder. These four parts are alternately colored in the direction of rotation around the cylinder axis, one in pink the other in green.

Les zones latérales sont colorées l'une uniquement en rose l'au tre uniquement en vert.The lateral zones are colored one only in pink the other only in green.

Quand le cylindre est immobile on se rend compte que les régions roses et vertes de la plage médiane paraissent visiblement identiques soit à la plage latérale rose soit à la plage latérale verte. Mais quand le cylindre tourne à une vitesse convennable pour tenir compte de la persistance des impressions lumineuses, la plage médiane parait beaucoup plus lumineuse que les plages latérales qui gardent la luminosité qu'elles présentaient au repos et le regard est attiré par l'éclat de la plage centrale. Le système fonctionne comme un gyrophare solaire c'est à dire sans qu'on ait besoin de lui apporter l'énergie lumineuse d'une lampe par exemple.When the cylinder is stationary, we realize that the pink and green regions of the median range appear visibly identical either to the pink lateral range or to the green lateral range. But when the cylinder rotates at a suitable speed to take account of the persistence of the luminous impressions, the median range appears much brighter than the lateral ranges which keep the luminosity which they presented at rest and the glance is attracted by the brightness of the central beach. The system works like a solar beacon, that is to say without the need to provide it with the light energy of a lamp for example.

S'il s'agit d'utiliser l'invention à des fins publiscitaires on peut s'y prendre de la façon suivante.If the invention is to be used for advertising purposes, this can be done as follows.

L'image publiscitaire est dessinée sur un support plan rectangu laire et transparent. On s'arrange pour qu'il y ait le plus possible d'espaces vierges d'impression sur le support transparent. Derrière ce support transparent et tout proche de lui c'est à dire quasi adjacent on fait padsser une bande de papier ou de toile sans fin tendue entre deux cylindres étroits sur lesquels elle passe. Ces deux cylindres sont mobiles autour de leurs axes qui sont placés chacun parallèlement à l'un des bords opposés du support transparent. La bande est ainsi tendue et forme une partie plane qui se déplace parallèlement au support transparent quand les cylindres l'entrainent en tournant.The advertising image is drawn on a rectangular and transparent planar support. We make sure that there is as much blank printing space as possible on the transparent support. Behind this transparent support and very close to it, that is to say almost adjacent, we tapssed a strip of endless stretched paper or canvas between two narrow cylinders on which it passes. These two cylinders are movable around their axes which are each placed parallel to one of the opposite edges of the transparent support. The strip is thus stretched and forms a flat part which moves parallel to the transparent support when the cylinders drive it by turning.

La bande sans fin est plus large et plus longue que le cadre de l'image de façon à l'encadrer de façon visible à travers le support sur une largeur de cinq à dix centimètres suivant l'importance du dessin à encadrer. Elle est divisée sur sa face visible en bandes parallèles de cinq à dix centimèttres de largeur par des segments de droites parallèles aux axes des cylindres.The endless band is wider and longer than the frame of the image so as to frame it visibly through the support over a width of five to ten centimeters depending on the size of the drawing to be framed. It is divided on its visible face into parallel strips of five to ten centimeters in width by segments of straight lines parallel to the axes of the cylinders.

Quand les cylindres tournent sur leurs axes, sous l'effet d'un moteur par exemple , les plages roses et vertes (constituées par les bandes parallèles de cinq à dix centimètres de largeur qu'on a alternativement colorées en rose et en vert) défilent sous l'image et sous ses bords. L'effet physiologique obtenu grâce à l'utilisation selon l'invention du phénomène de contraste successif attire l'oeil sur les parties à luminosité renforcée et par là sur l'image qu'elles parsèment et encadrent.When the cylinders turn on their axes, under the effect of a motor for example, the pink and green areas (constituted by the parallel bands of five to ten centimeters in width which one alternately colored in pink and in green) scroll under the image and under its edges. The physiological effect obtained thanks to the use according to the invention of the phenomenon of successive contrast draws the eye to the parts with enhanced brightness and thereby to the image which they dot and frame.

Puique l'invention porte sur des plages colorées, indépendament de la façon dont elles sont obtenues et que le concept inventif général consiste, une fois obtenues les plages colorées, à accroitre leur luminosité par utilisation adéquate du phénomène de contraste successif, il est évident que, sans sortir de ce concept inventif, on peut réaliser la coloration des plages du cylindre tournant, dans le cas du premier exemple, ou de la bande mobile dans le cas du deuxième, soit superficiellement soit dans la masse, et que si cette masse est transparente ou translucide on peut utiliser la remarque faite page 1 lignes 14 à 18 en plaçant une source de lumière à l'intérieur du cylindre ou de la bande.Since the invention relates to colored areas, independently of the manner in which they are obtained and that the general inventive concept consists, once the colored areas are obtained, of increasing their luminosity by adequate use of the phenomenon of successive contrast, it is obvious that , without departing from this inventive concept, it is possible to color the areas of the rotating cylinder, in the case of the first example, or of the moving strip in the case of the second, either superficially or in the mass, and only if this mass is transparent or translucent you can use the remark made on page 1 lines 14 to 18 by placing a light source inside the cylinder or the strip.

Il est évident aussi pour les mêmes raisons qu'on n'ajoute rien au concept inventif général en donnant au support d'image ou à la bande colorée une forme cylindrique circulaire au lieu d'une forme cylindrique allongée comme celle décrite dans le deuxième exemple.It is also obvious for the same reasons that nothing is added to the general inventive concept by giving the image carrier or the colored strip a circular cylindrical shape instead of an elongated cylindrical shape like that described in the second example. .
