Abstract
Description
La présente invention concerne un dispositif d'exposition de lunettes photochromiques à une source de lumière artificielle et ultraviolette. I1 est destiné à mettre en évidence les propriétés photosensibles de certains verres de lunettes solaires. La vente de lunettes solaires s'accompagne habituellement de la démonstration que les produits réagissent convenablement à une exposition solaire ou équivalente. Les produits d'exposition existants à ce jour utilisent une énergie importante pour produire un rayonnement ultraviolet artificiel suffisant pour faire réagir les verres photochromiques. En outre il sont traditionnellement développés à base de sources fluorescentes ou à décharge qui émettent un spectre beaucoup plus large que nécessaire pour produire l'effet recherché. La conséquence étant que les dispositifs actuels consomment trop d'énergie, sont toujours alimentés par le réseau électrique ou manquent d'autonomie si ils possèdent des batteries rechargeables. Enfin les sources de lumière ne sont pas dirigées ce qui nécessite l'usage de réflecteurs pour concentrer le flux sur les surfaces utiles. En conséquence de quoi les dispositifs actuels sont volumineux, lourds, inefficaces et manquent d'autonomie lorsqu'ils sont portatifs. Le dispositif présenté dans cette invention permet de corriger les inconvénients inhérents aux techniques employées jusqu'à présent. La partie produisant le flux énergétique ultraviolet est constitué de plusieurs LEDS (Light Emitting Diods) de puissance judicieusement placées par rapport à leur photométrie afin d'irradier la totalité des verres de manière homogène et directive sans perte de flux par réflexion. La longueur d'onde des sources est choisie convenablement pour obtenir un effet suffisant et adapté au type de verre à faire réagir. La longueur d'onde est choisie dans le spectre ultraviolet inférieure à 400nm pour engager la réaction de conversion photochromique. La puissance est adaptée à la distance et au temps d'exposition admissible par l'utilisateur, généralement une minute au plus. Le système est alimenté par des piles standard du marché facilement remplaçables ou rechargeables si leur type le permet. Un circuit électronique simple peut fixer le temps d'exposition au juste nécessaire afin d'économiser la source de courant alimentant les LEDS. Un bouton poussoir enclenche le démarrage du dispositif. En complément, les LEDS offrent une durée de vie accrue considérablement par rapport aux lampes à décharge et les dispositifs ainsi conçus n'auront plus besoin d'être entretenu pour changer les sources, ce qui simplifie également leur conception et leur coût. The present invention relates to a device for exposing photochromic glasses to a source of artificial and ultraviolet light. It is intended to highlight the photosensitive properties of certain glasses of sunglasses. The sale of sunglasses is usually accompanied by the demonstration that the products respond appropriately to sun exposure or equivalent. Existing exposure products to date use significant energy to produce artificial ultraviolet radiation sufficient to react photochromic lenses. In addition, they are traditionally developed based on fluorescent or discharge sources that emit a spectrum much larger than necessary to produce the desired effect. The consequence is that current devices consume too much energy, are always powered by the power grid or lack autonomy if they have rechargeable batteries. Finally the light sources are not directed which requires the use of reflectors to concentrate the flow on the useful surfaces. As a result, current devices are bulky, heavy, inefficient and lack autonomy when portable. The device presented in this invention makes it possible to correct the disadvantages inherent in the techniques employed hitherto. The portion producing the ultraviolet energy flux consists of several power LEDs (Light Emitting Diods) judiciously placed relative to their photometry in order to irradiate all the glasses in a homogeneous and directive manner without loss of flux by reflection. The wavelength of the sources is suitably chosen to obtain a sufficient effect and adapted to the type of glass to be reacted. The wavelength is chosen in the ultraviolet spectrum below 400 nm to initiate the photochromic conversion reaction. The power is adapted to the distance and to the permissible exposure time by the user, usually a minute or less. The system is powered by standard batteries easily replaceable or rechargeable market if their type allows. A simple electronic circuit can set the exposure time to just what it takes to save the power source to the LEDs. A push button triggers the start of the device. In addition, LEDs offer significantly longer life compared to discharge lamps and the devices designed will no longer need to be serviced to change sources, which also simplifies their design and cost.
Les dessins annexés illustrent cette invention, la figure (1) décrit en coupe la géométrie du dispositif, la position relative des différents éléments. La figure (2) décrit le principe d'alimentation des LEDS incluant le circuit de gestion du temps d'exposition. La figure (3) présente un exemple de ce dispositif en 3D. En référence à ces dessins, sur la figure (1), le dispositif comporte un boîtier (1) translucide sur une de ses faces, enveloppant les différents éléments nécessaires à son fonctionnement : - Un compartiment (2) recevant les piles d'alimentation (3). - Un circuit imprimé (4) supportant les composants électroniques et les sources ultraviolettes (5). - Deux embouts (6) refermant le boîtier (1) en extrémité. - Un poussoir (7) de mise en fonctionnement du dispositif. Le poussoir est accessible au travers de l'un des deux embouts (6) - Un reposoir (8) recevant la paire de lunette à exposer au flux lumineux. Ce reposoir peut être simplement constitué par la surface d'appui du dispositif pour une variante ouverte de celui-ci. Description du fonctionnement de ce mode de réalisation : après introduction d'une paire de verres solaires dans le dispositif, une impulsion sur le bouton poussoir (7) déclenche le passage du courant dans les diodes (5) pendant un temps de 30 secondes à titre d'exemple. Le schéma (2) donne le principe du câblage des sources en série avec un générateur de courant commandé par un poussoir et une minuterie. Les diodes ultraviolettes sont choisies avec une longueur d'onde de moins de 400nm pour rendre possible la réaction photochromique des verres solaires. La photométrie des sources est extensive (au moins 2x600) afin d'exposer toute la surface des verres de lunette placés à une distance minimale de 30mm. A titre d'exemple non limitatif, une puissance d'environ 4W (1W par source) est suffisante pour modifier les propriétés du verre dans le temps imparti par le passage du courant. La partie translucide du boîtier (1) permet de juger visuellement de la réaction et de la fin du cycle d'exposition du dispositif. L'utilisateur peut alors retirer les lunettes du reposoir (8) et apprécier la modification des propriétés de diffusion des verres. Le dispositif précédemment décrit est spécifiquement destiné à être utilisé dans des laboratoires d'optique ou des commerces de ventes de produits optiques solaires. I1 pourra être employé de façon simple et rapide à des fins de comparaison ou de promotion en magasin des produits de protection solaires. 1) 2) 10 3) 15 4) 20 5) 25 The accompanying drawings illustrate this invention, the figure (1) describes in section the geometry of the device, the relative position of the various elements. Figure (2) describes the principle of LEDs power supply including the exposure time management circuit. Figure (3) shows an example of this device in 3D. Referring to these drawings, in Figure (1), the device comprises a housing (1) translucent on one of its faces, enveloping the various elements necessary for its operation: - A compartment (2) receiving the battery ( 3). - A printed circuit (4) supporting the electronic components and ultraviolet sources (5). - Two end caps (6) closing the housing (1) at the end. - A pusher (7) for operating the device. The pusher is accessible through one of the two endpieces (6) - A repository (8) receiving the pair of glasses to be exposed to the luminous flux. This repository may simply be constituted by the support surface of the device for an open variant thereof. Description of the operation of this embodiment: after introduction of a pair of sunglasses into the device, a pulse on the push button (7) triggers the passage of the current in the diodes (5) for a period of 30 seconds as example. Diagram (2) gives the principle of wiring the sources in series with a current generator controlled by a pushbutton and a timer. The ultraviolet diodes are chosen with a wavelength of less than 400 nm to make possible the photochromic reaction of solar glasses. The photometry of the sources is extensive (at least 2x600) in order to expose the entire surface of the glasses of glasses placed at a minimum distance of 30mm. By way of non-limiting example, a power of approximately 4W (1W per source) is sufficient to modify the properties of the glass in the time allotted by the passage of the current. The translucent part of the housing (1) makes it possible to visually judge the reaction and the end of the exposure cycle of the device. The user can then remove the glasses from the repository (8) and appreciate the modification of the diffusion properties of the glasses. The device described above is specifically intended for use in optical laboratories or sales of solar optical products. It can be used in a simple and quick way for comparison or in-store promotion of sunscreen products. 1) 2) 10 3) 15 4) 20 5) 25
