Abstract

Electroluminescent gas lamp made from plastic material based on PMMA (polymethyl methacrylate) and PC (polycarbonate). The invention relates to the manufacture of electroluminescent tubes made from plastic materials PMMA and PC as a replacement for the conventional use of glass and quartz in this field. The invention is intended to be used for luminous display signs, advertising, decoration, lighting, signalling, works of art, medicine, scientific application, luminous display screens, etc.

Description

La présente invention concerne la fabrication de lampes électroluminescentes à gaz basse pression, excité par cathodes froides. The present invention relates to the manufacture of low pressure gas electroluminescent lamps, excited by cold cathodes.

La fabrication traditionnelle des tubes ou lampes électroluminescentes des tinee à l'usage d'enseignes lumineuses, publicité, décoration, éclairage, signalisation, médecine, soins de beauté, etc... Sont actuellement réalisés en verre ou quartz donc limites par une forme tubulaire et allongée. dont la longueur des tubes est limitée par les risques de casse et les difficultés de manipulation et de transport. The traditional manufacture of tubes or electroluminescent lamps of tinee for the use of luminous signs, advertising, decoration, lighting, signaling, medicine, beauty treatments, etc ... Are currently made of glass or quartz therefore limited by a tubular form and elongated. the length of the tubes of which is limited by the risk of breakage and the difficulties of handling and transport.

La presente invention permet de remédier à ces inconvénients en utilisant des matières plastiques à base de RMMA (poly méthacrylate de méthyle acrylique) et PC (poly carbonate), pour la fabrication d'enveloppe ou corps de lampe destines a contenir un gaz basse pression excite par cathodes froides.  The present invention makes it possible to remedy these drawbacks by using plastics based on RMMA (poly (acrylic methyl methacrylate)) and PC (poly carbonate), for the manufacture of an envelope or lamp body intended to contain an excited low pressure gas. by cold cathodes.

En raison des possibilités illimitées que permettent les matières plastique et assimiles à la création de forme et volume réalisable au gre des besoins spécifiques et artistiques de l'Homme de l'Art, il est plus juste de parler d'élément ou objets lumineux eectroluminescents, que de tube ou lampe dans l'ac- ceptation traditionnelle au sens le plus large consacre par l'usage. Because of the limitless possibilities that plastic materials and the like allow for the creation of form and volume achievable according to the specific and artistic needs of the skilled person, it is more correct to speak of an eectroluminescent element or luminous objects, than tube or lamp in traditional acceptance in the broadest sense enshrined in use.

Le principe de l'electroluminescence reste analogue à celui utilise pour la fabrication des néons d'enseignes lumineuses. The principle of electroluminescence remains analogous to that used for the manufacture of neon signs.

L'utilisation de matière plastique PMhA et PC, pour la fabrication d'éléments électroluminescents à gaz ne subissent aucune contrainte d'ordre thermique ou meca- nique, en raison, d'une part, de l'utilisation de cathodes froides, et d'autre part, de la basse pression des gaz. The use of PMhA and PC plastic material for the production of gas light emitting elements are not subject to any thermal or mechanical constraints, due, on the one hand, to the use of cold cathodes, and d on the other hand, the low gas pressure.

Le mode de coloration reste identique à celui des tubes Neon actuels, par l'utilisation de poudres fluorescentes, mais lie à un processus de fabrication différent. I1 est possible d'obtenir une variété de couleurs pour le même élément électroluminescent contrairement aux tubes Neon classiques en verre ne contenant qu'une couleur unique par élément de tube. The staining mode remains identical to that of current Neon tubes, by the use of fluorescent powders, but is linked to a different manufacturing process. It is possible to obtain a variety of colors for the same electroluminescent element, unlike conventional glass Neon tubes containing only one color per tube element.

L'utilisation de résines d'l.POXY comme support de circuit imprimé faisant ûffi,*e de cathodes d'@xcitation sont, pour certaines a?plicarlons, intègres au corps de l'élément plastique PMMA et PC. The use of resins of POXY as a printed circuit support making sufficient, and of excitation cathodes are, for some aplicarlons, integrated into the body of the plastic element PMMA and PC.

L'invention est particulièrement destinée à l'usage d'enseignes lumineuses, publicité, décoration, éclairage, signalisation, création artistique, médecine, soins de beauté, recherche de fraudes, application scientifique, éc@an d'animations lumineuses, etc...  The invention is particularly intended for the use of illuminated signs, advertising, decoration, lighting, signage, artistic creation, medicine, beauty treatments, search for fraud, scientific application, display of light animations, etc. .
