Description

Lampe d'éclairage public extérieur à diodes électroluminescentes et lampadaire ou réverbère équipé d' une telle lampe L'invention concerne une lampe d'éclairage public extérieur de type E40 et un lampadaire ou réverbère équipé d'une telle lampe.  The invention relates to an outdoor public lighting lamp of type E40 and a lamp or street lamp equipped with such a lamp.
ARRIERE PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
Actuellement, l'espace public extérieur (espaces urbains, infrastructures routières,...) et les grandes infrastructures industrielles ou commerciales (telles que les sites de production ou les centres commerciaux) sont équipés de systèmes d'éclairage extérieur à lampes à incandescence de type E40. Ces lampes fournissent un éclairage important, de l'ordre de 30000 à 38000 lumens, mais ont une consommation électrique et un coût d'entretien très élevés. A titre d'exemple, lorsqu'un hypermarché est équipé de 150 ampoules E40 d'une puissance électrique de 400 Watts, sa consommation électrique annuelle est d'environ 150 MWh. De plus, les lampes à incandescence ont une ampoule de verre relativement fragile et leur filament a une durée de vie de 12 000 heures environ. La casse et cette durée de vie relativement courte rendent nécessaires des changements de lampes relativement fréquents, ce qui occasionne des frais d'entretien lourds à supporter pour les collectivités ou entreprises.  Currently, outdoor public space (urban spaces, road infrastructures, ...) and large industrial or commercial infrastructures (such as production sites or shopping centers) are equipped with external lighting systems with incandescent lamps. type E40. These lamps provide significant lighting, in the order of 30000 to 38000 lumens, but have a very high power consumption and maintenance cost. For example, when a hypermarket is equipped with 150 E40 bulbs with an electric power of 400 Watts, its annual electricity consumption is about 150 MWh. In addition, incandescent lamps have a relatively fragile glass bulb and their filament lasts about 12,000 hours. The breakage and the relatively short lifespan necessitates relatively frequent lamp changes, which results in heavy maintenance costs to support for communities or businesses.
Depuis plusieurs années, pour l'éclairage domestique, les lampes à incandescence ont été remplacées par des lampes fluocompactes dites basse consommation puis par des lampes à diodes électroluminescentes (couramment appelées LED) . Ces différentes lampes ont permis d'importantes économies d'énergie.  For several years, for home lighting, incandescent lamps have been replaced by low-power fluorescent lamps and then by LED lamps (commonly called LEDs). These different lamps have resulted in significant energy savings.
Cependant, concernant les lampes E40 destinées à l'éclairage public extérieur, les essais menés pour remplacer les lampes à incandescence par ces nouvelles lampes n'ont pas été satisfaisants. En effet, bien que la consommation électrique soit beaucoup plus basse, ces nouvelles lampes diffusent une luminosité très inférieure aux lampes à incandescence. Par exemple, il existe sur le marché une lampe E40 à diodes électroluminescentes SMD qui consomme 17 Watts et produit une luminosité d'environ 2500 lumens, soit plus de 10 fois moins que les lampes à incandescence, très insuffisante pour un éclairage public extérieur. Il a été envisagé d'augmenter la luminosité produite par les lampes à diodes électroluminescentes mais l'augmentation de la luminosité s'accompagne d'une élévation importante de la température au niveau des diodes qui risque de conduire à une défaillance de la lampe ou tout au moins à une limitation de sa durée de vie. Ainsi, à l'heure actuelle, la quasi-totalité des lampes destinées à l'éclairage public sont encore à incandescence . However, concerning the E40 lamps intended for outdoor public lighting, the tests carried out for replace the incandescent lamps with these new lamps have not been satisfactory. Indeed, although the power consumption is much lower, these new lamps diffuse a much lower brightness than incandescent lamps. For example, there is on the market a lamp E40 SMD LED that consumes 17 Watts and produces a brightness of about 2500 lumens, more than 10 times less than incandescent lamps, very inadequate for outdoor public lighting. It has been envisaged to increase the brightness produced by LED lamps but the increase in brightness is accompanied by a significant rise in the temperature at the diodes which may lead to a lamp failure or any at least to a limitation of its life. Thus, at present, almost all lamps for public lighting are still incandescent.
OBJET DE L'INVENTION  OBJECT OF THE INVENTION
II serait donc intéressant de pouvoir disposer de lampes de type E40 ayant une consommation électrique inférieure et une luminosité équivalente à celles des lampes à incandescence d'éclairage urbain, avec une durée de vie relativement importante tout en permettant une maintenance facilitée.  It would therefore be interesting to have E40 type lamps having a lower power consumption and brightness equivalent to those of urban lighting incandescent lamps, with a relatively long life while allowing easy maintenance.
RESUME DE L'INVENTION  SUMMARY OF THE INVENTION
A cet effet, on prévoit, selon l'invention, une lampe comprenant un culot de type E40 et des diodes électroluminescentes placées sur un support et reliées au culot par un circuit électriquement conducteur. Le support et les diodes électroluminescentes sont logés dans une enceinte étanche formée au moins partiellement par une ampoule. Le support des diodes électroluminescentes comprend un radiateur tubulaire aux extrémités duquel sont ménagées des ouvertures d'aération autorisant une circulation d'air extérieur dans le radiateur. L'ampoule est constituée d'un matériau synthétique transparent ou translucide et est partiellement remplie d'un liquide, transparent ou translucide, dans lequel baignent les diodes électroluminescentes . For this purpose, according to the invention, there is provided a lamp comprising a base of the E40 type and electroluminescent diodes placed on a support and connected to the base by an electrically conductive circuit. The support and the light-emitting diodes are housed in a sealed enclosure formed at least partially by a light bulb. The support of the light-emitting diodes comprises a tubular radiator at the ends of which are provided with ventilation apertures allowing a circulation of outside air in the radiator. The ampoule is made of a transparent or translucent synthetic material and is partially filled with a liquid, transparent or translucent, in which the light-emitting diodes are immersed.
Les diodes électroluminescentes sont ainsi refroidies, d'une part, par un échange thermique par conduction avec le radiateur échangeant lui-même des calories par convection avec l'air qui y circule et, d'autre part, par un échange thermique par convection avec le liquide.  The light-emitting diodes are thus cooled, on the one hand, by a heat exchange by conduction with the radiator itself exchanging calories by convection with the air circulating thereon and, on the other hand, by a convective heat exchange with the liquid.
De préférence, le radiateur est pourvu intérieurement d'ailettes longitudinales en saillie.  Preferably, the radiator is provided internally with longitudinal fins projecting.
Ceci permet d'augmenter la surface d'échange du radiateur avec l'air circulant à l'intérieur du radiateur .  This increases the exchange surface of the radiator with the air flowing inside the radiator.
Dans un mode privilégié de réalisation de l'invention, le radiateur de la lampe est en plus muni d'un dispositif de ventilation forcée, comprenant avantageusement au moins un ventilateur monté à l'au moins une des extrémités du radiateur et, de préférence, à chacune de ses extrémités, c'est-à-dire d'une part entre le culot et le radiateur et d' autre part à l'extrémité du radiateur opposée au culot.  In a preferred embodiment of the invention, the radiator of the lamp is further provided with a forced ventilation device, advantageously comprising at least one fan mounted at the at least one of the ends of the radiator and, preferably, at each of its ends, that is to say on the one hand between the base and the radiator and on the other hand at the end of the radiator opposite the base.
Ce dispositif de ventilation a pour objet de renforcer la circulation d'air et d'améliorer ainsi le refroidissement .  This ventilation device is intended to enhance air circulation and thus improve cooling.
Dans une variante de l'invention, la lampe peut être munie d'une sonde thermique, qui pourra être logée à l'intérieur du support des diodes électroluminescentes et reliée à une unité de commande du dispositif de ventilation .  In a variant of the invention, the lamp may be provided with a thermal probe, which may be housed inside the support of the light emitting diodes and connected to a control unit of the ventilation device.
De manière préférentielle, les diodes électroluminescentes sont positionnées à intervalle régulier sur chaque face longitudinale du support qui est en forme de prisme régulier à section polygonale. Preferably, the electroluminescent diodes are positioned at intervals regular on each longitudinal side of the support which is in the form of a regular prism with polygonal section.
Le liquide dans lequel baignent les diodes électroluminescentes de la lampe objet de l'invention est préférentiellement une huile de synthèse, transparente, thermiquement inerte et électriquement isolante.  The liquid in which the light-emitting diodes of the lamp according to the invention are immersed is preferably a synthetic, transparent, thermally inert and electrically insulating oil.
La lampe sera de manière préférée en polycarbonate transparent.  The lamp will preferably be made of transparent polycarbonate.
Dans une variante de l'invention, la lampe est munie d'un transformateur qui pourra être à l'extérieur de la lampe ou pourra être intégré dans le support des diodes électroluminescentes.  In a variant of the invention, the lamp is provided with a transformer which may be outside the lamp or may be integrated in the support of the light-emitting diodes.
L' invention concerne en outre un dispositif d'éclairage extérieur public, comprenant une structure porteuse comportant un pied agencé pour permettre sa fixation au sol et une tête pourvue d'une telle lampe. Le dispositif comporte un transformateur, disposé dans la structure porteuse au voisinage du pied, reliant la lampe à une source extérieure d'électricité.  The invention further relates to a public outdoor lighting device, comprising a support structure comprising a foot arranged to allow its attachment to the ground and a head provided with such a lamp. The device comprises a transformer, disposed in the carrier structure in the vicinity of the foot, connecting the lamp to an external source of electricity.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION DE L' INVENTION  DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
En référence à la figure 1, la lampe conforme à l'invention comprend un culot 1, conforme au standard E40 et connu en lui-même, pourvu de conducteurs électriques (non représentés) formant un circuit d'alimentation électrique d'une source lumineuse. On rappelle que, dans « E40 », la lettre E indique qu'il s'agit d'un culot à vis et le chiffre 40 correspond au diamètre de la vis en millimètres .  Referring to Figure 1, the lamp according to the invention comprises a base 1, according to standard E40 and known in itself, provided with electrical conductors (not shown) forming a power supply circuit of a light source . It is recalled that in "E40", the letter E indicates that it is a screw base and the number 40 corresponds to the diameter of the screw in millimeters.
La source lumineuse est formée de diodes électroluminescentes 6 réparties sur un support fixé au culot 1, le tout placé dans une enceinte étanche 2 formée par une ampoule transparente 3 et remplie de liquide transparent ou translucide 4. Selon un mode particulier de réalisation de l'invention, la longueur du support est de 200 mm .  The light source is formed of light-emitting diodes 6 distributed on a support fixed to the base 1, all placed in a sealed enclosure 2 formed by a transparent bulb 3 and filled with transparent or translucent liquid 4. According to a particular embodiment of the invention, invention, the length of the support is 200 mm.
Le support comprend un radiateur tubulaire 5 ouvert en ses deux extrémités et pourvu à chacune desdites extrémités d'un embout 10a et 10b dans lequel sont ménagées des ouvertures d'aération 7a et 7b en communication avec l'extérieur.  The support comprises a tubular radiator 5 open at both ends and provided at each of said ends with a nozzle 10a and 10b in which are formed ventilation openings 7a and 7b in communication with the outside.
Le radiateur 5 peut être en différents matériaux thermiquement conducteurs. Dans le mode particulier de réalisation de l'invention ici décrit, le radiateur 5 est en aluminium qui présente une conductivité thermique élevée .  The radiator 5 may be of different thermally conductive materials. In the particular embodiment of the invention described here, the radiator 5 is made of aluminum which has a high thermal conductivity.
Les embouts 10a et 10b sont emboîtés sur les extrémités du radiateur tubulaire 5 et l'embout 10a est en outre agencé pour permettre la fixation du radiateur sur le culot 1, par exemple par emboîtement du culot 1 dans l'embout 10a. De manière préférée, le radiateur 5 comprend des ailettes longitudinales 5a en saillie vers l'intérieur. Les ailettes augmentent la surface d'échange thermique entre le support et l'air circulant dans celui- ci pour favoriser le refroidissement de l'enceinte. The end pieces 10a and 10b are fitted on the ends of the tubular radiator 5 and the end piece 10a is furthermore arranged to allow the radiator to be fixed to the base 1, for example by fitting the base 1 into the end piece 10a. Preferably, the radiator 5 comprises longitudinal fins 5a projecting inwards. The fins increase the exchange surface thermal between the support and the air flowing in it to promote cooling of the enclosure.
Les embouts 10a et 10b assurent la fixation de l'ampoule 3 autour du radiateur 5 et l'étanchéité de l'enceinte 2 au moyen de joints annulaires non représentés montés, d'une part, entre l'ampoule 3 et chacun des embouts 10a, 10b et, d'autre part, entre le radiateur 5 et chacun des embouts 10a, 10b.  The end pieces 10a and 10b ensure the fixing of the bulb 3 around the radiator 5 and the sealing of the chamber 2 by means of annular joints (not shown) mounted, on the one hand, between the bulb 3 and each of the nozzles 10a. , 10b and, on the other hand, between the radiator 5 and each of the end pieces 10a, 10b.
Dans le mode de réalisation privilégié de l'invention ici décrit, le refroidissement de l'enceinte 2 est réalisé de manière active à l'aide d'au moins un dispositif de ventilation forcée comportant deux ventilateurs 8a, 8b entraînés chacun par un moteur électrique 9a, 9b connecté au circuit d'alimentation électrique. Les moteurs 9a, 9b des ventilateurs 8a, 8b sont fixés chacun dans un logement ménagé au sein du radiateur 5 tel qu'illustré sur la figure 2. De manière préférée, la lampe objet de l'invention comporte un ventilateur à chacune de ses extrémités. Le premier ventilateur 8a est positionné entre le culot 1, et plus précisément l'embout adjacent 10 a, et le radiateur 5, dans un logement ménagé dans l'extrémité dudit radiateur 5. Le second ventilateur 8b est positionné à l'extrémité du radiateur 5 opposée au culot 1, lui aussi dans un logement ménagé dans ladite extrémité. Selon ce mode particulier de réalisation de l'invention, le refroidissement du radiateur 5 est ainsi activé par les deux ventilateurs 8a, 8b. L'homme du métier saura dimensionner, en fonction de la chaleur émise par les diodes électroluminescentes 6 et les autres composants de la lampe, le dispositif de ventilation et déterminer le nombre de ventilateurs nécessaires. Il saura également choisir le ventilateur adapté à la quantité de chaleur à dissiper. La vitesse de rotation des ventilateurs, le dimensionnement et la forme des pales seront déterminés en fonction de la quantité d'air à faire circuler dans le radiateur 5 pour évacuer la chaleur produite mais il sera également tenu compte du bruit engendré par le fonctionnement du ventilateur de manière à maintenir le bruit en question à un niveau suffisamment faible pour ne pas occasionner de gêne pour les piétons qui circuleraient sous un lampadaire équipé d'une lampe selon 1 ' invention . In the preferred embodiment of the invention described here, the cooling of the enclosure 2 is actively performed using at least one forced ventilation device comprising two fans 8a, 8b each driven by an electric motor. 9a, 9b connected to the power supply circuit. The motors 9a, 9b of the fans 8a, 8b are each fixed in a housing formed in the radiator 5 as illustrated in FIG. 2. Preferably, the lamp which is the subject of the invention comprises a fan at each of its ends. . The first fan 8a is positioned between the base 1, and more specifically the adjacent endpiece 10a, and the radiator 5, in a housing formed in the end of said radiator 5. The second fan 8b is positioned at the end of the radiator 5 opposite the base 1, also in a housing in said end. According to this particular embodiment of the invention, the cooling of the radiator 5 is thus activated by the two fans 8a, 8b. Those skilled in the art will be able to size, according to the heat emitted by the light-emitting diodes 6 and the other components of the lamp, the ventilation device and determine the number of fans necessary. He will also know how to choose the right fan for the amount of heat to dissipate. The speed of rotation of the fans, the dimensioning and the shape of the blades will be determined depending on the amount of air to be circulated in the radiator 5 to remove the heat produced but will also be taken into account the noise generated by the operation of the fan so as to maintain the noise in question at a level low enough not to cause inconvenience to pedestrians who would circulate under a lamppost equipped with a lamp according to the invention.
Les dispositifs de ventilation peuvent être à fonctionnement continu ou non. Leur fonctionnement, s'il n'est pas continu peut être déclenché lorsqu'une certaine température est atteinte. Dans une version améliorée de la lampe de l'invention, la lampe est à cette fin munie d'une sonde thermique reliée à un circuit de commande agencé pour commander la mise en route du moteur des ventilateurs en fonction de la température. Le circuit de commande est incorporé à la lampe. La sonde pourra être placée à l'extérieur de la lampe sur l'ampoule 3, à l'intérieur de l'enceinte dans le liquide transparent ou de manière préférée la sonde thermique 11 sera placée à l'intérieur du radiateur 5.  The ventilation devices may be continuous operation or not. Their operation, if it is not continuous, can be triggered when a certain temperature is reached. In an improved version of the lamp of the invention, the lamp is for this purpose provided with a thermal probe connected to a control circuit arranged to control the startup of the motor of the fans according to the temperature. The control circuit is incorporated in the lamp. The probe may be placed outside the lamp on the bulb 3, inside the enclosure in the transparent liquid or, preferably, the thermal probe 11 will be placed inside the radiator 5.
Le radiateur 5 forme un prisme régulier à section polygonale et les diodes électroluminescentes 6 sont fixées à intervalle régulier sur chacune des faces dudit radiateur 5. Selon un mode de réalisation privilégié, les diodes électroluminescentes 6 sont positionnées à intervalle régulier sur des bandelettes-supports fixées sur les faces du radiateur 5. Ceci simplifie la fixation des diodes électroluminescentes 6.  The radiator 5 forms a regular prism with a polygonal section and the light-emitting diodes 6 are fixed at regular intervals on each of the faces of said radiator 5. According to a preferred embodiment, the light-emitting diodes 6 are positioned at regular intervals on fixed support strips on the faces of the radiator 5. This simplifies the fixing of the light-emitting diodes 6.
L'homme du métier saura choisir le type de diodes le plus adapté. En particulier, les diodes SMD référence 3535 Flip-Led peuvent être préférentiellement utilisées. Selon un mode particulier de l'invention, le support comporte 12 faces comprenant chacune 10 diodes électroluminescentes, soit au total 120 diodes électroluminescentes qui permettent un éclairage à 360°. Une lampe de ce type aura une puissance de 150 W et produira une luminosité de 15 000 lumens environ. Selon d'autres modes de réalisation de l'invention, la puissance de la lampe, le nombre de faces du support et le nombre de diodes électroluminescentes peuvent être adaptés à l'utilisation qui sera faite de la lampe. A titre d'exemple, la puissance des lampes selon l'invention pourra être comprise de préférence entre 100 et 400 W pour diffuser entre 10 000 et 40 000 lumens environ. Bien entendu, le nombre de faces du support et le nombre de diodes électroluminescentes seront adaptés en fonction de la puissance et la répartition spatiale de 1 ' éclairement souhaitées ainsi que du type de diodes électroluminescentes utilisées, et éventuellement en fonction de la géométrie du réflecteur du lampadaire que la lampe est destinée à équiper. Those skilled in the art will be able to choose the most appropriate type of diode. In particular, SMD diodes reference 3535 Flip-Led may be preferentially used. According to one particular embodiment of the invention, the support comprises 12 faces each comprising 10 light-emitting diodes, ie a total of 120 diodes electroluminescent devices that provide 360 ° illumination. A lamp of this type will have a power of 150 W and will produce a brightness of about 15,000 lumens. According to other embodiments of the invention, the power of the lamp, the number of faces of the support and the number of light-emitting diodes can be adapted to the use to be made of the lamp. For example, the power of the lamps according to the invention may be preferably between 100 and 400 W to diffuse between 10,000 and 40,000 lumens approximately. Of course, the number of faces of the support and the number of light-emitting diodes will be adapted as a function of the desired power and spatial distribution of the illumination as well as the type of light-emitting diodes used, and possibly depending on the geometry of the reflector of the light emitter. street lamp that the lamp is intended to equip.
Comme précédemment indiqué, le radiateur 5 et les diodes électroluminescentes 6 sont logées dans une enceinte étanche 2 délimitée par une enveloppe ou ampoule 3. L'ampoule 3 est en matériau synthétique transparent ou translucide pour laisser passer tout ou partie du spectre lumineux émis par les diodes électroluminescentes 6. Le matériau utilisé peut avoir une fonction filtrante de certaines longueurs d'ondes afin d'obtenir un éclairage de la couleur souhaitée (par exemple à dominante jaune ou orange, bleu, ou blanc) . A titre d'exemple, l'homme du métier peut utiliser un polycarbonate ou un PVC . Le matériau utilisé a une résistance suffisante à la chaleur. Cette résistance à la chaleur est déterminée en fonction du dispositif de refroidissement qui en limitant 1 ' échauffement des diodes électroluminescentes 6 va limiter également l'élévation de la température de l'ampoule à une valeur que le matériau doit cependant pouvoir supporter. Enfin, le matériau choisi ne se dégrade pas au cours du temps relativement à la durée de vie minimale souhaitée pour la lampe : en particulier, il ne change pas de couleur. Dans un mode de réalisation privilégié, le matériau utilisé est un polycarbonate transparent et stable au cours du temps. Ce matériau a, de plus, la particularité d'avoir une résistance mécanique relativement importante, notamment aux chocs, rendant ainsi la lampe très résistante aux chutes et impacts . As previously indicated, the radiator 5 and the electroluminescent diodes 6 are housed in a sealed enclosure 2 delimited by an envelope or bulb 3. The bulb 3 is made of transparent or translucent synthetic material to allow all or part of the light spectrum emitted by the Light-emitting diodes 6. The material used may have a filtering function of certain wavelengths in order to obtain illumination of the desired color (for example predominantly yellow or orange, blue, or white). For example, one skilled in the art can use a polycarbonate or a PVC. The material used has sufficient resistance to heat. This heat resistance is determined according to the cooling device which by limiting the heating of the light emitting diodes 6 will also limit the rise in the temperature of the bulb to a value that the material must however be able to withstand. Finally, the chosen material does not does not degrade over time relative to the desired minimum lamp life: in particular, it does not change color. In a preferred embodiment, the material used is a polycarbonate transparent and stable over time. This material has, moreover, the particularity of having a relatively high mechanical strength, especially shock, thus making the lamp very resistant to falls and impacts.
Selon l'invention, l'ampoule 3 est partiellement remplie d'un liquide 4, qui participe au refroidissement des diodes électroluminescentes 6 et de l'enceinte 2. Le liquide utilisé est stable thermiquement dans les plages de températures rencontrées lors du fonctionnement de la lampe et ici n'est pas électriquement conducteur. Il est avantageusement non toxique pour l'homme et l'environnement, en cas de rupture de l'ampoule, et bien entendu, non inflammable. Les diodes électroluminescentes 6 dégageant de la chaleur, le liquide 4 doit posséder un coefficient de dilatation thermique permettant d'avoir une augmentation de pression acceptable par la lampe. De manière préférée, le liquide 4 utilisé est une huile de synthèse transparente, thermiquement inerte et électriquement isolante. Le volume introduit dans l'enceinte 2 doit permettre de baigner l'ensemble des diodes 6 quelle que soit l'orientation de la lampe. La partie de l'ampoule 3 ne contenant pas de liquide 4 contient de l'air qui en se comprimant va absorber l'augmentation de volume née de la dilatation du liquide 4. Dans le présent mode de réalisation, le volume de liquide 4 introduit représente au plus 90 % du volume total de l'enceinte 2. Il est entendu que l'homme du métier saura adapter le volume de liquide 4 en fonction de la taille de l'ampoule 3 utilisée et du volume occupé par le support des diodes électroluminescentes 6. Les bandelettes-supports des diodes électroluminescentes 6 sont en matériau de préférence thermiquement conducteur et/ou sont agencées pour ne pas recouvrir totalement le radiateur 5 de telle manière que le liquide 4 puisse échanger des calories par convection, non seulement avec les diodes électroluminescentes 6, mais également avec lesdites bandelettes et/ou le radiateur 5. According to the invention, the ampoule 3 is partially filled with a liquid 4, which contributes to the cooling of the light-emitting diodes 6 and the enclosure 2. The liquid used is thermally stable in the temperature ranges encountered during the operation of the lamp and here is not electrically conductive. It is advantageously nontoxic for humans and the environment, in case of breakage of the ampoule, and of course, non-flammable. Since the light-emitting diodes 6 emit heat, the liquid 4 must have a coefficient of thermal expansion that makes it possible to have an acceptable pressure increase by the lamp. Preferably, the liquid 4 used is a transparent synthetic oil, thermally inert and electrically insulating. The volume introduced into the chamber 2 must allow to bathe all the diodes 6 regardless of the orientation of the lamp. The portion of the ampoule 3 containing no liquid 4 contains air which, by squeezing, will absorb the increase in volume arising from the expansion of the liquid 4. In the present embodiment, the volume of liquid 4 introduces represents at most 90% of the total volume of the chamber 2. It is understood that the person skilled in the art will be able to adapt the volume of liquid 4 according to the size of the bulb 3 used and the volume occupied by the support of the diodes electroluminescent 6. The support strips of the light-emitting diodes 6 are of preferably thermally conductive material and / or are arranged so as not to completely cover the radiator 5 so that the liquid 4 can exchange calories by convection, not only with the light-emitting diodes 6, but also with said strips and / or the radiator 5.

Le circuit électronique 20 comprend à cette fin des moyens d'émission / réception pour sa liaison à l'unité de commande. Ces moyens d'émission / réception sont agencés pour permettre la transmission :  The electronic circuit 20 comprises for this purpose transmission / reception means for its connection to the control unit.

Dans ce perfectionnement, une autre fonctionnalité est ajoutée à la lampe. Il s'agit ici de l'intégration d'une fonction de capture d'images au sein même de la lampe. En effet, il ressort que le traitement des phénomènes d' insécurité urbaine passe de plus en plus fréquemment par le déploiement d'un système de vidéosurveillance ou de vidéoprotection . Or, le déploiement d'un tel système suppose l'implantation de caméras, opération qui se révèle relativement longue et coûteuse. En outre, les caméras, lorsqu'elles ne sont pas camouflées, deviennent elles-aussi l'objet d'actes de vandalisme . In this enhancement, another feature is added to the lamp. This is the integration of an image capture function within the lamp itself. Indeed, it appears that the treatment of urban insecurity phenomena is more and more frequently due to the deployment of a video surveillance or videoprotection system. However, the deployment of such a system involves the implementation of cameras, an operation that is relatively long and expensive. In addition, cameras, when not camouflaged, also become subject to vandalism.
Selon l'invention, un capteur d'images 21, par exemple de type CCD, est intégré à la lampe pour permettre la capture d'image et/ou la réalisation de vidéo.  According to the invention, an image sensor 21, for example of the CCD type, is integrated in the lamp to enable image capture and / or video production.
Le capteur d'images 21 est de préférence un capteur couleur faible bruit. En variante, le capteur d'images 21 peut être un capteur monochrome et/ou être d'un autre type tel qu'un capteur CMOS. La résolution et la définition du capteur seront déterminées en fonction des conditions de prise de vue et de la qualité d' image recherchée. Le capteur d'images 21 est alimenté par la lampe via le circuit électronique 20.  The image sensor 21 is preferably a low-noise color sensor. Alternatively, the image sensor 21 may be a monochrome sensor and / or be of another type such as a CMOS sensor. The resolution and definition of the sensor will be determined according to the shooting conditions and the desired image quality. The image sensor 21 is powered by the lamp via the electronic circuit 20.
Le capteur d'images 21 est ici monté sur l'extrémité du support opposée au culot 1. Le capteur d'images 21 est ici plus précisément fixé sur l'embout 10b.  The image sensor 21 is here mounted on the end of the support opposite the base 1. The image sensor 21 is here more precisely fixed on the tip 10b.
Un connecteur vidéo 22 est relié au circuit électronique 20 et est intégré à la lampe au voisinage du culot 1 de la lampe pour ramener l'image soit en mode analogique soit en mode numérique. La liaison entre le connecteur vidéo 22 et le circuit électronique 20 se fait par une nappe passant au centre du support.  A video connector 22 is connected to the electronic circuit 20 and is integrated with the lamp in the vicinity of the base 1 of the lamp to bring the image back either in analog mode or in digital mode. The connection between the video connector 22 and the electronic circuit 20 is via a sheet passing through the center of the support.
Le capteur d'images 21 est équipé d'une lentille agencée pour faire converger, vers le capteur d'images 21, les rayons lumineux de la scène observée de manière à projeter l'image de ladite scène sur le capteur d'images 21. La lentille est montée mobile et associée à un actionneur permettant un réglage de mise au point (focus) . Un filtre optique adapte le signal lumineux au capteur d'images 21.  The image sensor 21 is equipped with a lens arranged to converge, towards the image sensor 21, the light rays of the observed scene so as to project the image of said scene onto the image sensor 21. The lens is mounted movably and associated with an actuator allowing focus adjustment. An optical filter adapts the light signal to the image sensor 21.
De préférence, un déflecteur 23 en forme de cône est associé au capteur d'images 21 de manière à empêcher que la lumière produite par la lampe n'éblouisse le capteur d'images 21. Le déflecteur 23 aura une forme et une longueur déterminées en fonction de la puissance lumineuse de la lampe. Preferably, a deflector 23 in the form of a cone is associated with the image sensor 21 so as to prevent the light produced by the lamp from dazzling the image sensor 21. The deflector 23 will have a shape and a length determined according to the luminous power of the lamp.
Deux applications principales sont notamment envisageables :  Two main applications can be envisaged:
a) pour le résidentiel, le connecteur vidéo délivre un signal composite couleur au format PAL/SECAM compatible avec tous les moniteurs du marché. Un câble coaxial permet de ramener le signal vidéo vers le moniteur.  a) For residential, the video connector delivers a color composite signal in PAL / SECAM format compatible with all monitors on the market. A coaxial cable is used to bring the video signal back to the monitor.
b) pour les parkings et la voirie, le connecteur vidéo délivre un signal numérique au format JPEG compressé. Dans ce cas l'image peut être traitée par un ordinateur central déporté pour des applications de télésurveillance (recherche d'intrus par exemple).  b) For car parks and roads, the video connector delivers a digital signal in compressed JPEG format. In this case the image can be processed by a remote central computer for remote monitoring applications (search for intruders, for example).
c) en mode stand-alone, on peut envisager avec un processeur vidéo intégré sur la carte électronique de faire un traitement local de l'image pour allumer la lampe en cas d'intrusion ou autres.  c) in stand-alone mode, it is conceivable with a video processor integrated on the electronic card to make local processing of the image to turn on the lamp in case of intrusion or other.

L'ampoule est ici cylindrique mais peut prendre d'autres formes, comme d'autres formes de révolution avec ou sans renflement, par exemple en bulbe ou en sphère. Les formes convexes seront privilégiées de sorte à renforcer l'effet loupe formé avec le liquide.  The bulb is here cylindrical but can take other forms, like other forms of revolution with or without bulge, for example bulb or sphere. The convex shapes will be favored so as to reinforce the loupe effect formed with the liquid.
