Description

La présente invention concerne une ampoule d'éclairage comprenant un culot, un bulbe et un ensemble de LED logé dans ledit bulbe.The present invention relates to a light bulb comprising a base, a bulb and a set of LEDs housed in said bulb.

Contrairement à la majorité des zones urbaines, qui sont éclairées au moyen de sources de lumière individuelles puissantes mais espacées les unes des autres de plusieurs mètres, certains lieux de loisirs ou/et de promenade sont éclairés au moyen de nombreuses ampoules d'éclairage suspendues à un câble commun et distantes les unes des autres de quelques dizaines de centimètres seulement, formant ainsi des cordons ou guirlandes lumineuses. On trouve de telles guirlandes lumineuses entre autres dans des fêtes populaires, dans des allées de parcs, ou encore sur certains quais de ports lacustres où touristes et autochtones ont coutume de se promener le soir.Unlike most urban areas, which are lit by powerful individual light sources but spaced from each other by several meters, some recreational and / or boardwalk sites are illuminated by numerous light bulbs suspended from the street. a common cable and distant from each other only a few tens of centimeters, thus forming cords or light garlands. Such garlands of lights can be found among other things in popular festivals, in park alleys, or on certain quays of lacustrine ports where tourists and locals wander around at night.

À titre d'exemple, on peut citer la rade de Genève, où certains quais sont éclairés sur des longueurs de plusieurs centaines de mètres par des cordons lumineux composés d'ampoules à incandescence de puissance nominale 15 Watts. Pour que d'une part le flux lumineux global dispensé par ces cordons ne soit pas trop intense et ne soit pas ressenti comme agressif par les promeneurs, et d'autre part pour augmenter la durée de vie moyenne des ampoules individuelles, celles-ci sont alimentées sous une tension électrique de 30 volts, inférieure à la tension usuelle de 36 volts. Ceci a pour conséquence une double modification de leur aspect: d'une part elles diffusent une lumière dont le spectre est décalé vers les longueurs d'onde plus grandes, donc d'une teinte différente, qualifiée usuellement de nettement plus "chaude" que la teinte dite « lumière du jour » qu'elle diffuseraient sous tension nominale, et d'autre part le spectateur perçoit dans chaque ampoule une zone centrale lumineuse aux contours légèrement flous et une zone périphérique, correspondant aux contours géométriques du bulbe de l'ampoule, nettement moins lumineuse que la zone centrale. L'aspect particulier de ce mode d'éclairage de la rade de Genève bénéficie d'une large acceptation du public sur le plan esthétique, aspect que le public souhaite voir perdurer dans l'avenir.For example, we can mention the harbor of Geneva, where some platforms are lit on lengths of several hundred meters by light cords consisting of incandescent bulbs rated at 15 Watts. So that on the one hand the overall luminous flux dispensed by these cords is not too intense and is not felt as aggressive by walkers, and secondly to increase the average life of individual bulbs, they are powered at a voltage of 30 volts, lower than the usual voltage of 36 volts. This has the consequence of a double modification of their appearance: on the one hand they diffuse a light whose spectrum is shifted towards the longer wavelengths, and therefore of a different hue, usually described as much more "hot" than the shade called "daylight" that it would broadcast under nominal voltage, and secondly the viewer perceives in each bulb a bright central area with slightly fuzzy outlines and a peripheral area, corresponding to the geometric contours of the bulb of the bulb, much less luminous than the central area. The particular aspect of this mode of lighting of the bay of Geneva profits from a wide acceptance of the public on the aesthetic plan, aspect which the public wishes to see continue in the future.

Mais il est prévu, - et ce au niveau mondial -, que la production d'ampoules à incandescence soit abandonnée dans un proche avenir au profit de dispositifs d'éclairage basés sur des principes physiques différents, tels que les ampoules dites fluocompactes et les ampoules à LED. Or aucune de ces ampoules actuellement disponibles sur le marché, censées constituer une alternative aux ampoules à incandescence, ne permet d'obtenir l'aspect esthétique particulier de l'éclairage public décrit ci-dessus.But it is expected - globally - that the production of incandescent bulbs will be abandoned in the near future in favor of lighting devices based on principles different physical types, such as so-called compact fluorescent bulbs and LED bulbs. But none of these light bulbs currently available on the market, supposed to be an alternative to incandescent bulbs, does not achieve the particular aesthetic appearance of public lighting described above.

Le but de la présente invention est de réaliser une ampoule d'éclairage, offrant les caractéristiques optiques particulières décrites ci-dessus, et qui ne soit pas une ampoule à filament incandescent.The object of the present invention is to provide a light bulb, having the particular optical characteristics described above, and which is not an incandescent filament bulb.

Ce but est atteint grâce à une ampoule d'éclairage du type défini d'entrée, dans laquelle ledit ensemble de LED est agencé dans un module radiant dont le volume est inférieur ou égal à 4 cm3. De préférence le volume du module radiant est inférieur à 2 cm3.This object is achieved by means of a light bulb of the defined type of input, in which said set of LEDs is arranged in a radiant module whose volume is less than or equal to 4 cm 3 . Preferably the volume of the radiant module is less than 2 cm 3 .

L'agencement de l'ensemble des LED dans un tel volume restreint permet de simuler optiquement la disposition du fil incandescent d'une ampoule à incandescence.The arrangement of all the LEDs in such a restricted volume makes it possible to optically simulate the arrangement of the incandescent wire of an incandescent bulb.

Le module radiant peut présenter la forme d'un sphéroïde, proche de la forme de la zone centrale perçue par le spectateur regardant une ampoule à incandescence fonctionnant dans le mode particulier mentionné ci-dessus.The radiant module may have the shape of a spheroid, close to the shape of the central area perceived by the viewer looking at an incandescent bulb operating in the particular mode mentioned above.

Le module radiant peut également présenter la forme d'un bâtonnet prismatique dont l'axe longitudinal est sensiblement perpendiculaire à l'axe de symétrie de l'ampoule, ce qui correspond optiquement à certaines dispositions géométriques d'un fil incandescent d'une ampoule à incandescence. Ce bâtonnet prismatique peut en particulier présenter 3 faces.The radiant module may also have the shape of a prismatic rod whose longitudinal axis is substantially perpendicular to the axis of symmetry of the bulb, which corresponds optically to certain geometric arrangements of a glow wire of a light bulb. incandescence. This prismatic rod can in particular have 3 faces.

Dans un mode d'exécution géométriquement proche des ampoules éclairant la rade de Genève, le bulbe présente la forme d'une ampoule-poire.In an embodiment geometrically close to the bulbs illuminating the harbor of Geneva, the bulb has the shape of a bulb-pear.

De préférence, pour obtenir la différence d'aspect entre la zone centrale et la zone périphérique de l'ampoule, le bulbe est constitué de verre poudré.Preferably, to obtain the difference in appearance between the central zone and the peripheral zone of the bulb, the bulb is made of powdered glass.

Selon un mode d'exécution, le module électronique alimentant l'ensemble de LED, logé dans le culot, comprend un convertisseur fournissant un courant à intensité stabilisée. Ceci permet d'ajuster la tension d'alimentation, et donc la température de couleur de l'ampoule, en particulier en utilisant une tension d'alimentation des ampoules d'éclairage un peu plus basse que la tension nominale.According to one embodiment, the electronic module supplying the set of LEDs, housed in the base, comprises a converter providing a stabilized current. This makes it possible to adjust the supply voltage, and therefore the color temperature of the bulb, in particular by using a supply voltage of the light bulbs a little lower than the nominal voltage.

La température de couleur de l'ampoule d'éclairage selon l'invention est comprise entre 2000 et 3000° Kelvin et peut de préférence être comprise entre 2000 et 2500° Kelvin.The color temperature of the light bulb according to the invention is between 2000 and 3000 ° Kelvin and can preferably be between 2000 and 2500 ° Kelvin.

D'autres caractéristiques et avantages de l'invention apparaîtront à l'homme du métier au vu de la description ci-dessous d'un mode d'exécution particulier, en référence aux figures accompagnantes, où

  • la figure 1 est une vue en perspective et en coupe partielle d'une ampoule selon l'invention,
  • la figure 2 est une vue éclatée de l'ampoule de la figure 1 montant ses principaux composants.
Other features and advantages of the invention will become apparent to those skilled in the art from the following description of a particular embodiment, with reference to the accompanying figures, where
  • the figure 1 is a perspective view in partial section of a bulb according to the invention,
  • the figure 2 is an exploded view of the bulb of the figure 1 mounting its main components.

Les figures montrent une ampoule d'éclairage selon l'invention comprenant un culot (1), présentant un filetage extérieur (2) à la norme E 27 et un bulbe (3) en forme d'ampoule poire. Dans ce mode d'exécution, la longueur totale de l'ampoule est d'environ 104 mm, la longueur du bulbe seul est d'environ 85 mm, et le diamètre transversal maximal du bulbe est d'environ 60 mm.The figures show a light bulb according to the invention comprising a base (1), having an external thread (2) to the standard E 27 and a bulb (3) bulb-shaped bulb. In this embodiment, the total length of the bulb is about 104 mm, the bulb length alone is about 85 mm, and the maximum transverse diameter of the bulb is about 60 mm.

Le culot (1), dont l'enveloppe est métallique, a été représenté pour des raisons didactiques sur la figure 1 comme s'il était semi- transparent, pour mieux montrer l'agencement des pièces à l'intérieur de l'ampoule. Le bulbe est réalisé en verre poudré. Le choix du coefficient de diffusion de l'enveloppe du bulbe selon l'invention permet d'obtenir une nette différence de luminosité entre la zone centrale lumineuse et la zone périphérique du bulbe faiblement lumineuse , étant entendu que selon l'invention, et contrairement à l'effet optique généralement recherché dans les ampoules à bulbe diffusant, on évite ici une diffusion maximale de la lumière émise par la source de lumière, laquelle générerait un aspect homogène de l'ensemble du bulbe éclairant. Le choix du coefficient de diffusion de l'enveloppe du bulbe permet également de masquer la source de lumière pour le spectateur lorsque l'ampoule est éteinte et de rendre les contours de cette source de lumière flous lorsque l'ampoule est allumée.The base (1), whose envelope is metallic, has been represented for didactic reasons on the figure 1 as if it were semi-transparent, to better show the arrangement of the pieces inside the bulb. The bulb is made of powdered glass. The choice of the diffusion coefficient of the bulb envelope according to the invention makes it possible to obtain a clear difference in brightness between the central light zone and the peripheral zone of the weakly luminous bulb, it being understood that according to the invention, and contrary to the optical effect generally sought in bulb bulbs diffusing, here avoids a maximum diffusion of the light emitted by the light source, which would generate a homogeneous appearance of the entire illuminating bulb. The choice of the diffusion coefficient of the bulb envelope also makes it possible to mask the light source for the viewer when the bulb is off and to make the contours of this source of light blurry when the bulb is lit.

Each conductive element (7) is also welded to a power supply wire (9). The general outline of the radiant module (5) is thus that of a spheroid with plane facets. The volume of the radiant module (5) shown in the figures is about 3.8 cm 3 .
