Description

The present invention relates to a system for the electrical power supply of a light-emitting diode illumination device. BACKGROUND OF THE INVENTION The invention further relates to a light emitting diode illumination device and a ready-to-assemble assembly comprising the system and the device. The field of luminaires is moving towards a gradual abandonment of incandescent bulbs in favor of so-called "low consumption" bulbs for economic and environmental impact issues. The development of different low energy light bulb technologies involves the adaptation of different lighting devices to binding standards. For example, the power supply voltage of the sector is standardized sometimes differently in different countries. In lighting technology with light-emitting diodes, the supply voltages of the light-emitting diodes are much lower than the voltages conventionally provided by the power supply to the mains (approximately 110V or 230V). A transformer, or voltage adapter, is generally provided between the mains power supply and the light emitting diode lighting device. Existing LED lighting devices usually include a base for the power supply and a bulb with light emitting diodes with a voltage adapter. The standard size cap of the device connects to the mains, recovering the mains voltage. The mains voltage is transmitted to the voltage adapter inside the bulb. The voltage adapter converts the mains voltage into a supply voltage for the light-emitting diodes housed inside the bulb. The shape of the lighting device determines the shape of the bulb. The shape of the bulb determines the useful volume of the bulb in which the voltage adapter and the light-emitting diodes are housed. As a result, the voltage adapter and the light emitting diodes are adapted to the shape of the lighting device. The production of a new form of lighting device therefore entails significant design costs for the bulb, for the light-emitting diodes and for the voltage adapter.

There is therefore a need to design a system with a light emitting diode lighting device whose design costs are limited. For this, the invention proposes a system for powering a light-emitting diode lighting device, the system comprising: R: 130900A30999 NADS 1 \ 30999--100201 project v2.doc - 15/03/10 - 18:03 - 1/12 a socket of connection to the sector; a voltage adapter electrically connected to the connection socket, the voltage adapter being supplied from the mains via the connection socket and transforming the mains voltage into an operating voltage of the light-emitting diodes; a receiving member for receiving the lighting device, the receiving member being a receiving socket or a receiving cap and being electrically connected to the voltage adapter for supplying the received lighting device with the operating voltage electroluminescent diodes. According to a variant, the receiving member is adapted to receive the lighting device removably. Alternatively, the connection cap is selected from the group consisting of a screw bulb cap E27, a screw bulb cap E14 and a bayonet bulb cap B22. According to a variant, the receiving member is adapted to hold the lighting device in position. According to a variant, the receiving member is adapted to angularly orient the received lighting device and electrically powered by the receiving member. According to a variant, the system comprises an envelope connecting the connection cap and the receiving member, the voltage adapter being housed in the volume defined by the envelope, the receiving member and the connecting cap. Alternatively, the envelope has openings for ventilation of the voltage adapter and / or fins, openings and fins contributing to the cooling of the voltage adapter. The invention further proposes a light-emitting diode lighting device comprising a connecting member to the preceding system, the connecting member being adapted to be received by the receiving member of the system, the connecting member being a base connecting piece or a connecting socket adapted to cooperate respectively with the receiving socket or the receiving cap of the system. According to a variant, the device comprises a band-shaped structure and a ribbon of light-emitting diodes fixed on one side of the band-shaped structure. The invention also proposes a ready-to-assemble assembly comprising: the preceding system, and the preceding lighting device. R: 130900A30999 NADS 1130999--100201 Project v2.doc - 15/03/10 - 18:03 - 2/12 Other features and advantages of the invention will be apparent from the following detailed description of embodiments. of the invention, given by way of example only and with reference to the drawings which show: - Figure 1, a sectional view of a system for the power supply of a lighting device with light emitting diodes in a mode particular embodiment according to the present invention; - Figure 2, a perspective view of a first lighting device adapted to be received in the system of Figure 1; - Figure 3, a perspective view of a second lighting device adapted to be received in the system of Figure 1; - Figure 4, a perspective view of the assembly ready to mount comprising the system of Figure 1 and a third lighting device adapted to be received in such a system; - Figure 5, a side view of the system envelope for the power supply of a lighting device according to the present invention, in a particular embodiment; FIG. 6, a perspective view of the envelope of FIG. 5; - Figures 7 to 20, views of lighting devices according to the present invention, in particular embodiments.

The invention relates to a system for the power supply of a light-emitting diode (LED) lighting device. With reference to FIG. 1, in a particular embodiment, the system 20 comprises a base 22 for connection to the sector. The base 22 of connection is preferably selected from standard caps in the field of electric lighting. The base 22 can thus be chosen from the group consisting of an E27 screw bulb base, an E14 screw bulb base and a B22 bayonet bulb base. The screw bulb base E27 is preferred in that its use is widespread and in that it ensures a good maintenance of the system 20 in the socket to which it is connected. The base 22 of the mains connection makes it possible to supply the power supply to the system 20. The system further comprises a voltage adapter 24. The voltage adapter 24 is electrically connected to the connection base 22, for example to the using wire as shown in Figure 1. Typically, the mains voltage is in the voltage range 110 V to 120 V and 220 V to 250 V. The operating voltage of light emitting diodes is generally less than 50 V, for example 12 V. The voltage adapter 24 is used to transform the voltage of the R: 130900A30999 NADS 1 \ 30999--100201 projetv2.doc - 15/03/10 - 18:03 - 3/12 sector that supplies the system 20 in an operating voltage of light-emitting diodes. The voltage adapter includes any type of device for transforming a primary voltage into a secondary voltage. The voltage adapter is most commonly called a transformer. It should be noted, however, that the term "transformer" is not considered in a limiting manner. The voltage adapter can thus be a conventional transformer with primary and secondary coils. The voltage adapter can also be a switching power supply or any other electronic device transforming the amplitude of the voltage. The system further comprises a receiving member 26. The receiving member 26 is electrically connected to the voltage adapter 24. The receiving member 26, receiving a lighting device 40 of the type shown in Figs 2 at 4, supplies the lighting device 40 with the operating voltage of the light-emitting diodes. The receiving member 26 is either a receiving socket, or any other female type receiving member, a receiving cap, or any other type of male receiving member. With reference to FIGS. 2 and 3, the invention proposes an illumination device 40 with light-emitting diodes 48. The lighting device 40 comprises a connection member 42 adapted to be received by the receiving member 26 of the system 20 previously described. The connecting member 42 is either a connecting socket, or any other male connection member, or a connection socket, or any other female connection member. The connecting member 42 is selected from the connecting cap and the connecting sleeve so as to cooperate with the receiving socket or the receiving cap of the system 20 respectively. The receiving member 26 supplies the lighting device 40 with the operating voltage of the light-emitting diodes when the connection member 42 of the lighting device 40 is received by the reception receiving member 26. With reference to FIG. Figure 4, the invention provides a ready-to-assemble assembly comprising a system as previously described and comprising a lighting device as previously described. The light-emitting diode device 48 and the system 20 for powering a light-emitting diode device 48, including the voltage adapter 24, are thus separately produced. With reference to FIGS. 2 and 3, various forms of lighting devices 40 may be provided to be adapted to be received by a single R: 130900A30999 NADS 1 \ 30999--100201 project v2.doc - 15/03/10 - 18 The ability of the lighting device 40 to be received by the system is indifferent to the shape of the lighting device 40. Only the shape of the receiving member 26 and the form the connecting member 42 are fixed so as to cooperate with each other. Consequently, the shape of the lighting device 40 may vary, according to the preferences of the user, without causing any modification of the structure of the system 20 and therefore without incurring additional cost for the design of the system 20. The invention makes it possible to to obtain a system with a light-emitting diode lighting device whose design costs are limited.

The receiving member 26 may be adapted to receive the lighting device 40 removably. The reception of the connecting member 42 by the receiving member 26 is then removable. The removable nature of the reception of the connection member 42 of the lighting device 40 by the receiving member 26 allows the interchangeability of the lighting device 40 with another lighting device 40. FIG. another lighting device 40 adapted to be removably received in the system 20. The user can replace the light-emitting diode illumination device 40 with another light-emitting diode illumination device 40 without replacing the light-emitting diode device 40. tension 24. The user can vary its range of lights according to his desires using only one system 20, also called base. Moreover, the economic cost and the environmental impact for the realization of an additional voltage adapter are avoided, when the system described above is compared with the conventional solution of a light-emitting diode lighting device incorporating a power adapter. voltage inside the bulb. Thus, the system 20, the lighting device 40 and the ready-to-assemble assembly make it possible to obtain a lighting with light-emitting diodes that is economical and has a limited environmental impact.

The receiving member 26 may be adapted to hold the lighting device 40 in position. The system 20 then serves as a support for the lighting device 40 which does not require any other mechanical support to be in position. Thus the assembly consisting of the system 20 and the lighting device 40 is devoid of other means for holding the lighting device 40 in position.

The assembly consisting of the system 20 and the lighting device 40 can in turn be maintained solely by means of the mains socket with which the connection terminal 22 is connected. R: 130900A30999 NADS 1 \ 30999-100201 projetv2.doc - 15/03/10 - 18:03 - 5/12 With reference to Figure 1, the holding of the lighting device 40 by the receiving member 26 can be provided by a receiving member 26 in form receiving bushing having a circumferential groove 34. The circumferential groove 34 is adapted to receive a radial projection of the connecting cap of the lighting device 40. The receiving member 26 may be a female receiving bush having a tapping suitable for receiving a thread of a connecting sleeve 42 of the lighting device 40. The receiving sleeve 26 having a tapping may be similar to a female socket cooperating with a standard screw cap E27 or E14. The receiving member 26 may be adapted to angularly orient the lighting device 40 that it receives. The angular orientation of the device can be defined with respect to the main axis of the receiving member 26 (the vertical axis in the embodiment of Figure 1). The lighting device 40 is then received and electrically powered by the receiving member 26 which provides an angular orientation of the lighting device 40. The angular orientation can also be called adjustment of the lighting device 40. The reception by the receiving member 26 provides power to the lighting device 40 regardless of the orientation chosen for the lighting device 40 relative to the system 20. Referring to Figure 1, the embodiment of the organ the receiving power supply 26 may be provided in the form of a receiving socket having a circumferential groove 34. The power supply of the lighting device 40 received by the receiving socket may then comprise an electrical contact 36 on the inner periphery of the receiving socket. and an electrical contact 38 at the bottom of the receiving socket. The electrical contact 36 can be connected to the voltage adapter 24 by means of a wire passing through the receiving socket, for example via a bore. The lighting device 40 is received by engagement, or clipping, in the receiving socket. Then, by symmetry of revolution about the axis of the receiving sleeve and the power supply (the vertical axis in the case of Figure 1), the lighting device 40 can be rotated to adjust its angular orientation . Such an embodiment of the power supply in the receiving socket makes it possible to obtain at a lower cost a receiving member 26 adapted to angularly orient the lighting device.

Such an embodiment of the receiving member 26 may not be adapted to angularly orient the lighting device 40. Indeed in this case, the angular orientation of the lighting device with respect to the axis of the receiving member 26, the axis of the screw, causes an axial displacement of the lighting device R: 130900A30999 NADS 1 \ 30999--100201 project v2.doc - 15/03/10 - 18:03 - 6/12 40 in the receiving socket. The lighting device 40 then moves away from the central electrical contact of a conventional receiving socket of the standard caps E27 or E14, because of its axial displacement. The transmission of the current can then no longer be ensured for all the angular positions of the lighting device 40 with respect to the system 20. The system 20 previously described only supplies a light-emitting diode supply voltage to the receiving socket and to the device lighting that is received. It may thus be preferred that the dimensions of the receiving socket 26 differ from the dimensions of the E27 and E14 standards in order to prevent the use of the system with conventional bulbs, having a supply voltage of 110V or 230V. With reference to FIGS. 5 and 6, the system 20 may comprise a casing 28 connecting the connection cap 22 and the receiving member 26. This casing 28 makes it possible to simply produce the mechanical connection between the connection cap 22 and the casing 22. receiving member 26. The voltage adapter 24 can then be housed in the volume defined by the envelope 28, the receiving member 26 and the connecting socket 22. This allows a compact design of the system 20. The system 20 can thus easily connect to any type of luminaire without having an impact on the visual and physical environment close to this luminaire.

With reference to FIG. 1, the voltage adapter 24 is preferably housed in the cylindrical volume defined by the internal diameter D of the connection cap 22 and by a height H between the bottom of the connection cap 22 and the connection. Such an embodiment of the system 20 is particularly compact and has little impact on the environment of a luminaire with which the system connects and visual aesthetics for the user. With reference to FIGS. 5 and 6, the envelope 28 may comprise ventilation openings 30. These openings 30 allow ventilation of the voltage adapter 24. Air circulation is then possible between the external environment of the system assembly 20 / lighting device 40 and voltage adapter 24.

The casing 28 may, alternatively or additionally, comprise fins 32. The fins 32 and the ventilation openings 30 contribute to the cooling of the voltage adapter 24. This ensures that the heat released by the voltage adapter 24 during operation is well evacuated and does not damage the lighting device 40 or the system 20.

The fins 32 are preferably made of a very good thermally conductive material, more particularly aluminum. The system 20 may include an insulating ring 27 of the casing 28 with respect to the connection base 22. This insulating ring 27 makes it possible to make the connection R: 130900A30999 NADS 1 \ 30999-100201 projetv2. doc - 15/03/10 - 18:03 - 7/12 without making any electrical connection between the base of the connection and the envelope 28, which may be metallic. With reference to FIGS. 2 and 3, the lighting device 40 with light-emitting diodes may comprise a structure 44 in the form of a strip. A ribbon 46 of light-emitting diodes 48 may be attached to one side of the web-like structure 44. The ribbon 46 of light-emitting diodes 48 is flexible and is easily installed on the strip-shaped structure 44 which may comprise numerous variations of curvature according to the user's tastes. The ribbon 46 may for example be self-adhesive.

Strands 46 of stabilized light emitting diodes 48 of model 3528 from Ledtek are preferably used. The length of these self-adhesive tapes varies according to the shape and size of the structure but does not exceed two meters in length, which implies a maximum consumption of 9.6 Watt. In such an embodiment of the invention, the voltage adapter delivers a supply voltage of the 12V light emitting diodes with a maximum power of 10 watts. The insulation ring and / or the structure 44 can be made of ecological material. Such materials can be recycled and / or recyclable. Preferably, resins of plant origin are used, more particularly liquid wood such as Arboform (registered trademark), Arbofill (registered trademark), and Arboblend (registered trademark) of Tecnaro GmbH. With reference to FIGS. 7 to 9, the structure 44 of the lighting device 40 is in the form of a strip, the strip describing a plurality of floral motifs. With reference to FIG. 10, the strip of the structure 44 may describe a form of lampshade. With reference to FIG. 11, the strip of the structure 44 may describe a square shape. With reference to Fig. 12, the web of the structure 44 may describe a circle shape.

With reference to Figures 13 and 14, the web of structure 44 may describe an animal shape. With reference to Figures 15 and 16, the structure 44 may comprise a plurality of bands or ridges. The light emitting diode ribbon 48 may be attached to one of the edges of the structure 44. Fig. 15 shows a diamond shaped illumination device 40, Fig. 16 shows an inverted pyramid-shaped illumination device 40. Referring to Fig. 17, the structure 44 may comprise a plurality of intersecting bands. The light emitting diode ribbon 48 may be attached to one of the strips of the structure 44. FIG. 17 represents a lighting device 40 formed of a plurality of bands in the form of intersecting circles. The structure 44 may be a surface or a volume. Figure 18 shows a lighting device 40 in the form of a sphere. The sphere of FIG. 18 has a helical groove for placing the light emitting diode ribbon 48. With reference to FIG. 19, the structure 44 may comprise a spiral-forming band. The strips constituting the structure 44 of the lighting device 40 may describe three-dimensional curves as illustrated by the helical strip shown in FIG. 20.
