Etat de la techniqueState of the art

Le document FR-A-2513740 décrit une lampe électrique portative selon le préambule de la revendication 1, comprenant une lampe d'éclairage à ampoule unique, ayant un sous-ensemble constitué par une bague d'actionnement et un réflecteur, lequel est animé d'un mouvement combiné de rotation et de translation pour piloter l'interrupteur d'allumage et d'extinction de l'ampoule, et le réglage de la focalisation du faisceau lumineux émis par l'ampoule.FR-A-2513740 discloses a portable electric lamp according to the preamble of claim 1, comprising a single bulb lighting lamp, having a subassembly consisting of an actuating ring and a reflector, which is animated by a combined movement of rotation and translation to control the switch of ignition and extinction of the bulb, and the adjustment of the focus of the light beam emitted by the bulb.

Le document FR-A-2708714 se rapporte à une lampe d'éclairage à double foyer lumineux, utilisant deux ampoules insérées dans un circuit électrique, lequel est équipé de deux interrupteurs commandés par un barreau de commutation rotatif. Le réglage de la focalisation du faisceau émis par l'une des ampoules est opéré au moyen d'un bouton spécial distinct de l'organe de commande du barreau.FR-A-2708714 relates to a dual-focus light lamp, using two bulbs inserted in an electrical circuit, which is equipped with two switches controlled by a rotary switch bar. The focus adjustment of the beam emitted by one of the bulbs is operated by means of a special button separate from the control member of the bar.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser une lampe électrique portative, permettant d'obtenir un double éclairage et un réglage de la focalisation par une manipulation simple et rapide.The object of the invention is to provide a portable electric lamp, to obtain a dual illumination and focus adjustment by simple and fast manipulation.

La lampe selon l'invention est caractérisée en ce que le circuit d'allumage comporte en plus un deuxième intervalle de sectionnement pour l'alimentation d'une deuxième ampoule lorsque ladite bague d'actionnement se trouve dans une troisième position angulaire prédéterminée.The lamp according to the invention is characterized in that the ignition circuit further comprises a second sectioning gap for supplying a second bulb when said actuating ring is in a third predetermined angular position.

Selon une caractéristique de l'invention, le premier intervalle de sectionnement est commuté dans l'état fermé avant la fermeture du deuxième intervalle de sectionnement pour assurer l'allumage séquentiel de la première ampoule, puis de la deuxième ampoule. Il peut également être commuté dans l'état fermé avant la fermeture du deuxième intervalle de sectionnement pour assurer le cycle inverse d'allumage séquentiel de la première ampoule, puis de la deuxième ampoule.According to a feature of the invention, the first sectioning interval is switched to the closed state before the closing of the second sectioning interval to ensure the sequential ignition of the first bulb, then the second bulb. It can also be switched in the closed state before the closing of the second sectioning interval to ensure the reverse cycle sequential ignition of the first bulb, then the second bulb.

Préférentiellement, la première ampoule est une ampoule à incandescence ou à halogène pour l'éclairage lointain, et la deuxième ampoule est constituée par une diode LED pour l'éclairage rapproché, les deux ampoules étant connectées en parallèle.Preferably, the first bulb is an incandescent or halogen bulb for distant lighting, and the second bulb is constituted by an LED for close lighting, the two bulbs being connected in parallel.

La deuxième ampoule peut être solidaire du premier réflecteur fixé à la bague, en étant excentrée par rapport à la première ampoule.The second bulb may be integral with the first reflector attached to the ring, being eccentric with respect to the first bulb.

La deuxième ampoule peut également être montée fixe sur une patte de l'enveloppe, et en regard d'une rainure circulaire ménagée dans le premier réflecteur, le secteur de ladite rainure correspondant à la course angulaire de la bague rotative.The second bulb can also be fixedly mounted on a lug of the casing, and facing a circular groove formed in the first reflector, the sector of said groove corresponding to the angular stroke of the rotary ring.

Selon une autre variante, la deuxième ampoule est disposée en dehors du premier réflecteur, et est logée dans un orifice de l'enveloppe.According to another variant, the second bulb is disposed outside the first reflector, and is housed in an orifice of the envelope.

Le premier réflecteur peut être doté d'un manchon mobile en translation et en rotation avec la bague, le manchon provoquant la commutation des deux intervalles de sectionnement, alors que la première ampoule est disposée dans une douille fixe.The first reflector may be provided with a sleeve that is movable in translation and in rotation with the ring, the sleeve causing the switching of the two cutting intervals, while the first bulb is disposed in a fixed socket.

Le premier réflecteur est assujetti à la bague rotative, laquelle peut être bloquée en translation lorsque son filetage interne coopère avec le filetage conjugué d'un embout cylindrique d'une paroi intermédiaire. La douille de support du socle de la première ampoule est portée par ladite paroi intermédiaire mobile en translation pour assurer la commutation des deux intervalles de sectionnement et le réglage de la focalisation.The first reflector is subject to the rotating ring, which can be locked in translation when its internal thread cooperates with the conjugate thread of a cylindrical tip of an intermediate wall. The support socket of the base of the first bulb is carried by said movable intermediate wall in translation to ensure the switching of the two sectioning intervals and the adjustment of the focus.

Le deuxième réflecteur 30 est plus petit que le premier réflecteur 28.A focusing device 24 comprises a transparent pane 26 allowing the passage of the light beam coming from the bulb 12 or the diode 14, a parabolic reflector 28 coaxially surrounding the central bulb 12, and a second eccentric reflector 30 surrounding the diode 14. LED, which is housed by interlocking in a hollow support 32. The second reflector 30 is smaller than the first reflector 28.

La vitre 26 qui recouvre le premier réflecteur 28, le deuxième réflecteur 30 et la diode LED 14, est relié à une bague 34 rotative, vissée sur une extrémité filetée 36 de l'enveloppe 16 pour actionner la commande d'allumage de l'ampoule 12 et de la diode LED 14, et le réglage de la focalisation du faisceau lumineux. Le plateau 18 est équipé d'une douille 38 tubulaire servant de logement au socle 40 métallique de l'ampoule 12.The window 26 which covers the first reflector 28, the second reflector 30 and the LED 14, is connected to a rotating ring 34, screwed onto a threaded end 36 of the casing 16 to actuate the ignition control of the bulb 12 and the LED 14, and the focus adjustment of the light beam. The plate 18 is equipped with a tubular sleeve 38 serving as a housing for the metal base 40 of the bulb 12.

La borne de contact 42 de l'ampoule 12 coopère en position de fermeture avec un premier élément de contact 44, lequel est relié électriquement au bloc d'alimentation. Le circuit d'allumage comprend un premier intervalle de sectionnement 46 formé par une paire de pièces ou lames de contacts 46a, 46b, un deuxième intervalle de sectionnement 47 à contacts 47a, 47b, et des moyens pour la mise en série de l'ampoule 12 et de la diode LED 14. La lame de contact 46b coopère avec un contact glissant 48 logé dans une encoche de guidage d'un manchon 50, et est reliée au socle 40 de l'ampoule 12.The contact terminal 42 of the bulb 12 cooperates in the closed position with a first contact element 44, which is electrically connected to the power supply unit. The ignition circuit comprises a first sectioning gap 46 formed by a pair of contacts or blades 46a, 46b, a second sectioning gap 47 with contacts 47a, 47b, and means for the series connection of the bulb. 12 and the LED 14. The contact blade 46b cooperates with a sliding contact 48 housed in a guide notch of a sleeve 50, and is connected to the base 40 of the bulb 12.

Pendant le mouvement de rotation de la bague 34 intervient le réglage du dispositif de focalisation 24 et la commande du circuit d'allumage de l'ampoule 12 et de la diode LED 14 par la translation du réflecteur 28.During the rotational movement of the ring 34 is involved the adjustment of the focusing device 24 and the control of the ignition circuit of the bulb 12 and the LED 14 by the translation of the reflector 28.

Dans la figure 1, la diode LED 14 est allumée suite à la fermeture du deuxième intervalle de sectionnement 47, et l'ampoule 12 est éteinte étant donné que les lames de contacts 46a, 46b du premier intervalle de sectionnement 46 sont dans l'état ouvert. Le contact glissant 47b du deuxième intervalle de sectionnement 47 est relié à l'un des pôles du bloc d'alimentation à travers l'élément de contact 52. L'autre pôle est connecté électriquement à l'élément de contact 48a de la diode 14 via le contact glissant 48, la borne 42 de l'ampoule 12, le filament 12a, le socle métallique 40 et le contact de masse 46b. La diode LED 14 semiconductrice ne conduit que dans un sens, permettant à l'ampoule 12 de servir de conducteur de liaison pour l'alimentation de la diode 14.In FIG. 1, the LED 14 is lit following the closing of the second sectioning interval 47, and the bulb 12 is extinguished since the contact blades 46a, 46b of the first sectioning gap 46 are in the state open. The sliding contact 47b of the second sectioning gap 47 is connected to one of the poles of the power supply unit through the contact element 52. The other pole is electrically connected to the contact element 48a of the diode 14 via the contact sliding 48, the terminal 42 of the bulb 12, the filament 12a, the metal base 40 and the ground contact 46b. The semiconductor LED 14 only leads in one direction, allowing the bulb 12 to serve as a connecting conductor for the supply of the diode 14.

Dans la figure 2, la diode LED 14 est éteinte suite au retrait du contact de masse 46b avec le contact glissant 48, et à l'ouverture du contact 47b. L'ampoule 12 est allumée par la venue en engagement des lames de contacts 46a, 46b du premier intervalle de sectionnement 46. L'actionnement poursuivi de la bague 34 permet le réglage du dispositif de focalisation 24. La diode LED 14 et le deuxième réflecteur 30 sont entraînés par le premier réflecteur 28 lors la rotation de la bague 34 d'actionnement.In FIG. 2, the LED 14 is extinguished following the withdrawal of the ground contact 46b with the sliding contact 48, and at the opening of the contact 47b. The bulb 12 is ignited by the engagement of the contact blades 46a, 46b of the first sectioning gap 46. The continued actuation of the ring 34 allows the adjustment of the focusing device 24. The LED 14 and the second reflector 30 are driven by the first reflector 28 during the rotation of the actuating ring 34.

Les figures suivantes représentent différentes réalisations de lampes d'éclairage, reprenant le même système séquentiel de réglage du dispositif de focalisation 24 et de commande du circuit d'allumage de l'ampoule 12 et de la diode LED pour différentes positions de la bague d'actionnement 34. L'ampoule 12 et la diode LED 14 sont montées électriquement en parallèle.
Les mêmes numéros de repères seront utilisés pour désigner des pièces identiques ou similaires.
The following figures represent different embodiments of lighting lamps, using the same sequential system of adjustment of the focusing device 24 and control of the ignition circuit of the bulb 12 and the LED diode for different positions of the ring. actuation 34. The bulb 12 and the LED 14 are electrically connected in parallel.
The same reference numbers will be used to designate identical or similar parts.

Sur les figures 3 à 5, la diode LED 14 est fixée directement sur le réflecteur 28, l'autre réflecteur 30 des figures 1 et 2 étant supprimé. La paroi intermédiaire 18 est fixe, ainsi que l'ampoule 12, et le manchon 50 solidaire du réflecteur 28 traverse un orifice 60 de la paroi intermédiaire 18. Le premier intervalle de sectionnement 46 comporte une pièce de contact 46a mobile coopérant avec l'extrémité du manchon 50, et disposée en regard de la borne 42 de l'ampoule 12. Un ressort de compression 62 est intercalé entre le fond du compartiment 20, et la pièce de contact 46a en la sollicitant dans le sens de la fermeture. Le deuxième intervalle de sectionnement 47 est composé d'un premier élément de contact 47a logé dans la douille 38 isolante en étant en contact permanent avec le socle 40 de l'ampoule 12, et une deuxième pièce de contact 47b se déplaçant avec le manchon 50.In FIGS. 3 to 5, the LED 14 is fixed directly on the reflector 28, the other reflector 30 of FIGS. 1 and 2 being eliminated. The intermediate wall 18 is fixed, as is the bulb 12, and the sleeve 50 secured to the reflector 28 passes through an orifice 60 of the intermediate wall 18. The first cutting gap 46 comprises a movable contact piece 46a cooperating with the end of the sleeve 50, and disposed opposite the terminal 42 of the bulb 12. A compression spring 62 is interposed between the bottom of the compartment 20, and the contact piece 46a by urging it in the direction of closure. The second sectioning gap 47 is composed of a first contact element 47a housed in the insulating bushing 38 being in permanent contact with the base 40 of the bulb 12, and a second contact piece 47b moving with the sleeve 50 .

La pièce de contact 46a mobile est reliée par un fil souple 64 à l'un des pôles de la source d'énergie, et le premier élément de contact 47a est connecté à l'autre pôle par un conducteur 66. Les deux bornes de la diode LED 14 sont branchées respectivement à la deuxième pièce de contact 47b par un conducteur 67, et par un conducteur 70 à un contact glissant 68 en liaison avec la pièce de contact 46a. On respectera bien entendu la polarité de la diode 14 en connectant l'anode au pôle positif de la source d'énergie à courant continu.The movable contact piece 46a is connected by a flexible wire 64 to one of the poles of the energy source, and the first contact element 47a is connected to the other pole by a conductor 66. The two terminals of the LED 14 are respectively connected to the second contact piece 47b by a conductor 67, and a conductor 70 to a sliding contact 68 in connection with the contact piece 46a. Of course, the polarity of the diode 14 will be respected by connecting the anode to the positive pole of the DC power source.

Dans la position de repos illustrée aux figures 3 et 3A, les deux intervalles de sectionnement 46 et 47 sont ouverts, l'ampoule 12 et la diode LED 14 étant éteintes. La bague 34 est vissée à fond sur l'extrémité filetée 36 de l'enveloppe 16, et la pièce de contact 46a est écartée au maximum de la borne 42 de l'ampoule 12. La distance entre les contacts ouverts du premier intervalle de sectionnement 46 est supérieure à celle du deuxième intervalle de sectionnement 47.In the rest position illustrated in FIGS. 3 and 3A, the two sectioning intervals 46 and 47 are open, the bulb 12 and the LED 14 being extinguished. The ring 34 is screwed fully onto the threaded end 36 of the casing 16, and the contact piece 46a is spaced apart as far as possible from the terminal 42 of the bulb 12. The distance between the open contacts of the first cutting gap 46 is greater than that of the second sectioning gap 47.

Sur la figure 4, la rotation de la bague 34 dans le sens du dévissage provoque un mouvement combiné de rotation et de translation de l'ensemble réflecteur 28 et manchon 50. La diode LED 14 est entraînée en rotation de la position B (figure 3A) vers la position C (figure 4A), et la deuxième pièce de contact 47b vient en engagement contre la première pièce de contact 47a en provoquant l'allumage de la diode LED 14. La pièce de contact 46a se rapproche de la borne 42, mais l'ampoule 12 reste éteinte par suite de l'ouverture du premier intervalle de sectionnement 46.In FIG. 4, the rotation of the ring 34 in the unscrewing direction causes a combined movement of rotation and translation of the reflector assembly 28 and sleeve 50. The LED 14 is rotated from the position B (FIG. 3A) towards the position C (FIG. 4A), and the second contact piece 47b comes into engagement with the first contact piece 47a, causing the LED 14 to turn on. The contact piece 46a approaches the terminal 42, but the bulb 12 remains off as a result of the opening of the first sectioning gap 46.

Sur la figure 5, la rotation poursuivie de la bague 38 dans le même sens entraîne la diode LED 14 vers la position D. Le deuxième intervalle de sectionnement 47 s'ouvre, et la diode LED 14 s'éteint. Suite au recul du manchon 50, le ressort 62 pousse la pièce de contact 46a contre la borne 42 avec une pression prédéterminée, et permet l'allumage de l'ampoule 12. Lorsque le dévissage de la bague 34 se poursuit de la position D vers la position A (figure 5A), la pièce de contact 46a reste immobilisée en position de fermeture, et le manchon 50 se déplace avec le réflecteur 28 avec un mouvement relatif par rapport à l'ampoule 12 fixe. On obtient alors la focalisation du faisceau lumineux émis par l'ampoule 12. Après enlèvement de la bague 34, l'ampoule 12 reste allumée.In FIG. 5, the continued rotation of the ring 38 in the same direction causes the LED 14 towards the position D. The second sectioning interval 47 opens, and the LED 14 goes out. Following the recoil of the sleeve 50, the spring 62 pushes the contact piece 46a against the terminal 42 with a predetermined pressure, and allows the ignition of the bulb 12. When the unscrewing of the ring 34 continues from the position D towards the position A (Figure 5A), the contact piece 46a remains immobilized in the closed position, and the sleeve 50 moves with the reflector 28 with a relative movement relative to the fixed bulb 12. The focusing of the light beam emitted by the bulb 12 is then obtained. After removal of the ring 34, the bulb 12 remains on.

L'actionnement de la bague 34 rotative entre les positions B et A permet d'effectuer l'extinction complète de la lampe dans la position de repos, l'allumage et l'extinction de la diode LED 14, l'allumage de l'ampoule 12, et le réglage de la focalisation.Actuation of the rotating ring 34 between the positions B and A makes it possible to completely extinguish the lamp in the rest position, to turn on and off the LED 14, to turn on the light. 12 bulb, and focus adjustment.

Sur la variante des figures 6 à 8, la diode LED 14 n'est pas solidarisée au réflecteur 28 mobile, et est montée fixe sur une patte 72 de l'enveloppe 16. Le réflecteur 28 est pourvu d'une rainure 74 circulaire permettant le passage de la diode LED 14 lors de la rotation de la bague 34. Le contact glissant 68 est supprimé, le conducteur 70 étant soudé directement sur la pièce de contact 46a. Le fonctionnement de l'allumage et du réglage de la focalisation est identique à celui décrit précédemment.In the variant of FIGS. 6 to 8, the LED 14 is not secured to the movable reflector 28, and is fixedly mounted on a tab 72 of the envelope 16. The reflector 28 is provided with a circular groove 74 enabling the passage of the LED 14 during the rotation of the ring 34. The sliding contact 68 is removed, the conductor 70 being welded directly to the contact piece 46a. The operation of the ignition and the adjustment of the focus is identical to that described above.

Sur une autre variante illustrée aux figures 9 à 11, la diode LED 14 est logée en dehors du réflecteur 28 dans un orifice 76 du compartiment postérieur 20 de l'enveloppe 16. La structure et le fonctionnement restent identiques à ceux décrits précédemment.In another variant illustrated in Figures 9 to 11, the LED 14 is housed outside the reflector 28 in an orifice 76 of the rear compartment 20 of the casing 16. The structure and operation remain identical to those described above.

En référence aux figures 12 à 14, le réflecteur 28 et la bague 34 peuvent tourner par rapport à l'enveloppe 16, mais sont bloqués en translation. L'extrémité filetée 36 sur laquelle est vissée la bague 34 est dans ce cas solidarisée à la paroi intermédiaire 18, tandis que le bout de la bague 34 est doté d'un ergot 78 engagé dans une rainure annulaire de l'enveloppe 16 fixe. Le manchon 50 est supprimé, et la diode LED 14 est montée sur une patte 80 de la paroi 18 en regard de la rainure 74 circulaire du réflecteur 28. La douille 38 n'est pas solidarisée au réflecteur 28, et se déplace en translation avec la paroi 18 lors de la rotation de la bague 34. La borne 42 est en permanence en contact avec une pièce de contact 146a, et les deux intervalles de sectionnement 146 et 147 sont déportés au niveau d'un interrupteur à trois positions situé dans le compartiment antérieur 22.With reference to FIGS. 12 to 14, the reflector 28 and the ring 34 can rotate with respect to the envelope 16, but are locked in translation. The threaded end 36 on which is screwed the ring 34 is in this case secured to the intermediate wall 18, while the end of the ring 34 is provided with a lug 78 engaged in an annular groove of the casing 16 fixed. The sleeve 50 is removed, and the LED 14 is mounted on a tab 80 of the wall 18 facing the circular groove 74 of the reflector 28. The sleeve 38 is not secured to the reflector 28, and moves in translation with the wall 18 during the rotation of the ring 34. The terminal 42 is permanently in contact with a contact piece 146a, and the two sectioning intervals 146 and 147 are deported at a three-position switch located in the front compartment 22.

L'interrupteur à trois positions comporte une pièce de contact 146a solidaire de la douille 38, une première pièce de contact 147a fixe en liaison avec un pôle de la source d'énergie, et une deuxième pièce de contact 147b entraînée par la paroi 18 mobile.The three-position switch comprises a contact piece 146a integral with the sleeve 38, a first contact piece 147a fixed in connection with a pole of the energy source, and a second contact piece 147b driven by the movable wall 18 .

Dans la position de repos de la figure 12, les deux intervalles de sectionnement 146 et 147 de l'interrupteur sont ouverts, et l'ampoule et la diode LED 14 sont éteintes. La douille 38 traverse l'orifice central du réflecteur 28.In the rest position of FIG. 12, the two sectioning intervals 146 and 147 of the switch are open, and the bulb and the LED 14 are extinguished. The sleeve 38 passes through the central orifice of the reflector 28.

Lors du dévissage de la bague 34 à la figure 13, la paroi 18 recule en entraînant en translation l'ampoule 12 et la diode LED 14. Le réflecteur 28 tourne, mais sans mouvement de translation. La deuxième pièce de contact 147b vient d'abord en contact avec la première pièce de contact 147a pour fermer le deuxième intervalle de sectionnement 147, pour l'allumage de la diode 14.When the ring 34 is unscrewed in FIG. 13, the wall 18 moves back by driving the bulb 12 and the LED 14 in translation. The reflector 28 rotates, but without translational movement. The second contact piece 147b first comes into contact with the first contact piece 147a to close the second sectioning gap 147, for the lighting of the diode 14.

Sur la figure 14, la rotation poursuivie de la bague 34 provoque la fermeture du premier intervalle de sectionnement 146, et l'ouverture du deuxième intervalle de sectionnement 147 pour l'allumage de l'ampoule 12. L'extinction de la diode LED 14 peut intervenir avant ou après l'allumage de l'ampoule 12 en fonction des distances des deux intervalles de sectionnement 146 et 147. Le recul poursuivi de la douille 38 qui sort de l'orifice du réflecteur 28, permet ensuite de régler la focalisation du faisceau lumineux émis par l'ampoule 12.In Figure 14, the continued rotation of the ring 34 causes the closing of the first sectioning interval 146, and the opening of the second sectioning gap 147 for the ignition of the bulb 12. The extinction of the LED 14 can intervene before or after the illumination of the bulb 12 as a function of the distances of the two sectioning intervals 146 and 147. The continued retreat of the sleeve 38 which leaves the orifice of the reflector 28, then makes it possible to adjust the focus of the light beam emitted by the bulb 12.

Sur la variante des figures 15 à 17, on reconnaît la même structure de la lampe des figures 12 à 14, à l'exception de la diode LED 14 qui ne se déplace pas en translation.In the variant of FIGS. 15 to 17, the same structure of the lamp of FIGS. 12 to 14 is recognized, with the exception of the LED 14 which does not move in translation.

La figure 18 montre une lampe équipée d'une ampoule 12 et de trois diodes LED 14. Ces dernières peuvent être allumées simultanément ou séquentiellement selon que le circuit d'allumage comporte un ou plusieurs intervalles de sectionnement 147.FIG. 18 shows a lamp equipped with a bulb 12 and three LEDs 14. These can be lit simultaneously or sequentially according to whether the ignition circuit has one or more sectioning intervals 147.
