Definitions

  • the present invention is in the field of lighting devices implementing at least one electrical light source, such as a diode or the like, supplied with energy from a distant electrical source, such as electricity from the distribution network. .
  • the lighting device of the present invention finds particular application to the presentation of small items for their enhancement and / or their observation, such as in the fields of: jewelry, jewelery, watchmaking, perfumery and others or its application to mood lighting.
  • a general problem in the field of lighting devices lies in the constraint of the connection between the light source and the power supply source. This constraint for example imposes on the user to have a wired connection between the light source and the power supply to the electrical energy distribution network, which limits the possibilities offered to the user to place the lighting device relatively freely. according to his needs
  • the present invention seeks to overcome, it is sought the possibility of having an easily manageable light source for illuminating small articles, with a view to their enhancement, their presentation and / or their observation.
  • the presentation of items to customers is optimized by their lighting condition.
  • their development is optimized from their individual lighting.
  • the object of the present invention is to provide a lighting device comprising a support for at least one light source powered by energy from a remote source, which allows any displacement of the light source on the support while maintaining its power supply.
  • the device of the present invention is a lighting device comprising a support carrier of at least one light source, and means for connecting said light source to a remote power source.
  • This source of electrical energy is in particular the distribution network.
  • the inventive step of the present invention has been to exploit the properties of the inductive loops to power the light source without wire connection between it and the remote power supply source. More particularly, it is proposed to equip the support with an inductive loop transmitter supplied with energy from the remote source, by a wire link or the like in particular, so that this inductive loop is generating a magnetic field enveloping the support.
  • the light source is in turn carried by a pad, which is equipped with a core such as ferrite, this core being disposed inside a receiving inductive loop connected to the terminals of the light source.
  • the magnetic field produced by the transmitting loop generates a current in the receiving loop, this current being used to supply the light source with energy.
  • connection between the support and the light source on the one hand, and the energy link between the remote source and the light source, do not in any way constitute an obstacle to the free movement of the light source on the support without interruption of its power supply.
  • the light source is likely to be unique, but that it is advantageous to provide the device with a plurality of light sources that can be placed at various points on the board, or that can form together a pattern of which the conformation is given freely by the user according to his creative spirit.
  • a device of the present invention will be more specifically recognized in that said support is a plate receiving the light source on one of its large, apparent faces. At least one emitter inductive loop is disposed under the other large masked face of the tray and is connected to the remote power source. The light source is in turn carried by a stud equipped with at least one core placed inside a receiving inductive loop whose end strands are in relation to the terminals of the light source.
  • the power supply of the light source is performed without wired connection with the remote power source.
  • the light source carrying pin is able to be freely and easily moved by sliding on the apparent face of the plate and placed at any point thereof in the perimeter defined by the loop. transmitter, without breaking the power supply of the light source.
  • the stud is simply attached to the plate by depositing it on the apparent face of the plate, without having to use means or a fastener interposed between the stud and the plate. As a result, the stud can quickly and easily be put in place or removed from the board.
  • the number and arrangement of the emitting loops used are determined according to the dimensions of the surface of the plate to be traversed by the magnetic field induced by these loops, and according to the power of the power supply current of the emitter loop at least . It will be understood that according to various embodiments, either the emitter loop is single and substantially borders the periphery of the plate, or the emitter loops are in plurality being substantially disposed adjacently, to delimit together the overall surface of the plate traversed by the magnetic field. In the case where the transmitting loops are in plurality, these loops are preferably arranged overlapping their adjacent edge.
  • the transmitting loop is preferably connected to the network via a low voltage network voltage transformer.
  • Said low voltage is for example between 2V and 5V, and more particularly is preferably of the order of 3 V.
  • Such low voltage has appeared suitable for the supply of a light source advantageously consisting of a light emitting diode.
  • the plate is in particular of insulating material.
  • the material constituting the plate is any of the materials of the group of materials including wood, plastics, glass and ceramics.
  • the device comprises means for retaining the stud against its spontaneous sliding on the surface of the plate.
  • the tray is coated with a metal film, the pad being provided with at least one magnet disposed beyond the periphery of the receiving loop.
  • These provisions are intended to allow immobilization by magnetization of the light source on the plate, in particular to prevent spontaneous sliding of the light sources, during a displacement of the plate for example.
  • the tray is likely to be oriented inclined station and / or vertical, such orientation does not cause a fall of light sources through the presence of the retaining means. It should be noted that the advantageous exploitation of magnetic means for constituting said retaining means does not affect the freedom of movement of the light sources at any point on the board.
  • the metal film is advantageously formed by depositing a paint or varnish loaded with metal particles. It has become apparent that the use of such a paint or varnish provides satisfactory results as to the metallization of the plate without this metallization affecting the cooperation between the transmitting loop and the receiving loop.
  • the magnet that includes the pad is in turn preferentially shaped as a ring surrounding the receiving loop.
  • the plate is for example provided with a base for its orientation in horizontal station, or is provided with support members for its orientation in inclined station and / or vertical.
  • the base is advantageously organized in a box housing the emitter loop.
  • a preferred application of a lighting device of the present invention is the presentation of small items. Such an application is particularly useful in jewelery or jewelery, for example, to present jewelry or precious stones to customers. According to such an application, the stud is advantageously used to further constitute a support member of the article to be presented.
  • a lighting device comprises a plate 1, on the apparent face of which plate 1 rest light sources 2, such as light emitting diodes.
  • An inductive inductive loop 3 is disposed under the plate 1, in the masked face of the latter.
  • This transmitting loop 3 is supplied with energy from the distribution network 4 of electrical energy, through a transformer 5 of the network voltage at a low voltage of the order of 3 V.
  • the plate 1 is supported by a base 1 ', forming a box which houses the emitter inductive loop 3.
  • the power supply of the emitter loop 3 produces a magnetic field enveloping the plate 1, and in particular through the latter.
  • the light sources 2 are each carried by a stud 6.
  • This stud 6 is provided with a receiver inductive loop 7 inside which a ferrite core 8 is placed.
  • magnetic field produced by the emitter loop 3 induces a current in the receiving loop 7, this current being used to supply power to the light sources 2.
  • the light sources 2 can be freely moved to the apparent surface of the plate 1, or even be removed and deposited on the board 1 by a simple gesture of the user.
  • the pads 6 are equipped on their underside with a magnetic washer 9, arranged around the receiving loop 7.
  • the apparent face of the plate 1 is in turn coated with a film metal 10, formed of a layer of paint or varnish loaded with metal particles.
  • the emitter loop 3 is shaped so as to surround the periphery of the plate 1. These arrangements are particularly implemented when the dimensions of the plate 1 are not too substantial, such as the order of 400 mm per 100 mm. In Fig.3, the plate 1 is of rectangular conformation, while in Fig.4, the plate 1 is of circular conformation.
  • a plurality of transmitting loops 3 are arranged under the plate 1. These arrangements are notably implemented when the plate 1 is of large size.
  • the emitter balls 3 are arranged adjacent, their adjacent edges, such as 11 and 12 for example, being overlapped.
