Description

Kit for the realization of a luminaire

The subject of the present invention is a kit for producing a luminaire intended more particularly, but not exclusively, for public lighting, and which is suitable for urban or peri-urban areas as well as rural areas or any other location. requiring such lighting.

In fact, the present invention intends to provide a universal response to the problems which currently arise both technically and aesthetically in the production of well-made luminaires.

To this end, the main objective of the invention is to provide a solution based on the technology of light-emitting diode lamps (or “LED lamps”), a solution whose implementation is based on the assembly of a few very structural elements. simple and compact designed so as to present a standard character, making it possible to offer a range of luminaires adapted to a multiplicity of configurations, offering an infinite possibility of design, as well as various performances, improved compared to conventional devices in terms of longevity, energy consumption and lighting quality.

Another objective of the present invention is also to propose a solution making it possible to generate uniform lighting, allowing the public to identify possible obstacles and changes of direction while limiting any phenomenon of glare which is a source of discomfort, or even of setting in danger especially of pedestrians or road users.

In other words, the present applicant has imagined a solution in which the lighting and aesthetic appearance functions of a luminaire can practically be ensured by its LED optic in its own right, which is made autonomous and present plural functions, and only requires for its installation a support on which to hang it by means of a fastening member, the latter two can, if necessary, also contribute to giving the luminaire the desired final design.

To this end, the subject of the invention is a kit for producing a luminaire, said kit comprising:

- a housing of which at least one face is at least partially glazed, housing at least one printed circuit board on which is mounted at least one light-emitting diode oriented in the direction of the at least partially glazed face,

a support for hanging said box above an area to be lit, and

- A member for securing the housing to said support, comprising at least one housing designed capable of accommodating at least part of the housing, and a nozzle allowing the housing to be fixed to said support.

In accordance with an alternative embodiment of the kit according to the invention, the connection member comprises an articulation connecting said housing and said end piece.

Furthermore, it has also been imagined that in certain cases, said joining member may comprise a bodywork designed capable of at least partially covering said case.

According to a preferred embodiment of the invention, the latter can also be designed so as to include a bottom surmounted by a peripheral wall delimiting a space of shape and dimension adjusted as a function of the number of printed circuit boards hosted by said housing, said space being closed by said at least partially glazed face.

It is also advantageously provided that said housing comprises means capable of dissipating the heat emitted by said light-emitting diode, and which can in particular be defined by the bottom and the peripheral wall of the housing made of a thermal conductive material chosen from the group comprising: aluminum, aluminum alloy, steel, composite material.

Another characteristic of the invention is further defined by the fact that said space is subdivided into at least two coplanar compartments by means of at least one "V" bar having two opposite flanks joined by a vertex and extending along from the bottom of the case so that its top is oriented towards the at least partially glazed face of said case.

Furthermore, it can also be provided that the at least partially glazed face rests and is fixed on a shoulder extending between the internal face and the free edge of the peripheral wall of the housing, and which may include, where appropriate, a groove provided with a seal.

An additional characteristic of the present invention is further defined by the fact that the bottom and / or the peripheral wall of the housing include threaded orifices intended to allow the fixing of said housing of the fastening member on said housing by means of screws.

It can also be provided that said housing preferably houses electrostatic protection means of said printed circuit board.

Another advantageous characteristic of the kit according to the invention is further defined by the fact that the support comprises means for controlling the printed circuit board through a wire connection.

The present invention will be better understood on reading the description of exemplary embodiments made with reference to the appended figures, in which:

FIG. 3 illustrates a sectional view along AA of the box of FIG. 2,

FIG. 4 illustrates a perspective view of a section along BB of the box of FIG. 2, an area of which has been enlarged to facilitate understanding of the invention, and

FIG. 5 is a perspective view of another alternative embodiment of the fastening member of the kit according to the invention connected to the box of FIG. 2.

Referring to the figures, the present invention relates to a kit for producing a luminaire 1 consisting of different structural elements, which are advantageously each available in the form of a range, and which can therefore be specifically selected to correspond to the needs also expressed. both in terms of lighting and final aesthetic appearance of the luminaire 1.

In particular, the kit according to the invention comprises, as a basic structural element, a housing 2 integrating all of the optical, electronic and electrical means of the luminaire 1 and therefore, by itself, ensuring at least the lighting function of the last. Indeed, as will be seen in more detail below, the box 2 can also determine on its own the final aesthetic appearance of the luminaire 1.

In the illustrated alternative embodiment, the box 2 has a shape of a block comprising a bottom 3 surmounted by a peripheral wall 4 delimiting a space 5 designed capable of accommodating four printed circuit boards 6 each carrying a plurality of light-emitting diodes 7. Of course , the housing 2 could also host a different number of printed circuit boards 6 or have another shape, for example that of a disk of appropriate thickness, or any other shape that meets the expectations expressed.

It should be noted that the performance of the light emitting diodes 7 mounted on each of the printed circuit boards 6 is improved by the presence of lenses 70, preferably interchangeable, which make it possible to obtain a photometric distribution by refraction of the light radiation much higher by quality to that of a reflection distribution obtained by means of conventional discharge lamps.

Furthermore, with reference to the figures, the space 5 is covered by a face 8 comprising a glazed area 9, preferably made of tempered glass with high impact resistance or any other material with equivalent properties, and capable of allowing the passage of light radiation emitted by light-emitting diodes 7.

In this regard, it is expected that the glazed face 8 rests on a shoulder 10, extending between the internal face 40 and the free edge 41 of the peripheral wall 4 of the housing 2, and on which it is fixed, for example to the using an adhesive of suitable composition. Furthermore, the space 5 is sealed by means of a seal, disposed between the glazed face 8 and the shoulder 10, in a groove 11 which the latter comprises. It should be noted that, in accordance with a preferred variant embodiment, provision may be made for the adhesive used to fix the glazed face 8 to the shoulder 10 to jointly act as a seal.

According to the invention, the printed circuit boards 6 are advantageously arranged in the space 5 in such a way that they are in contact with both the bottom 3 and the peripheral wall 4 of the housing 2, which are advantageously made in one thermal conductive material such as for example aluminum, an aluminum alloy, a steel, a composite material, or any other material having equivalent properties.

Thanks to such a structure, the printed circuit boards 6 take advantage of the mass of the body of the box 2 which, acting as a radiator, cools rapidly in contact with the outside air. The housing 2 as such thus makes it possible to control the heating inherent in the operation of the light-emitting diodes 7, and to prevent them from being subjected to temperatures above about 85 ° C. In fact, in known manner, beyond this threshold, the integrity of the light-emitting diodes 7, and consequently their longevity, is threatened.

According to another characteristic of the invention, in the illustrated embodiment, the space 5 is subdivided, by means of three bars 13 with a “V” section, into four coplanar compartments 12, each housing a printed circuit board 6. The bars 13 each have two opposite sides 14a, 14b joined by an apex 15, and extend along the bottom 3 of the housing 2 so that their apex 15 is oriented towards the glazed face 8 of the housing 2 .

In fact, each of the bars 13 is specifically studied, structured and arranged in space 5 so as to define a surface playing the role of an anti-glare wall for a user of the area in which the luminaire 1 is located. In other words, the presence of the bars 13 makes it possible to confer excellent performance in terms of comfort on the luminaire 1 which moreover already has excellent performance in terms of lighting through the lenses 70.

In addition, the bars 13 have the advantage of each defining an additional heat exchange surface, making it possible to contribute to the dissipation of the heating induced by the light-emitting diodes 7 when they are operating. In other words, the presence of the bars 13 makes it possible to reduce the heat given off by the electronic circuit boards 6 even more effectively and therefore to contribute to extending the longevity of the luminaire 1.

With a similar objective of preserving the integrity of the luminaire 1, and of eliminating any maintenance operation, such as in particular the replacement of the bulbs, the present invention also provides that the volume available inside the box 2, outside space 5, is designed capable of receiving all the electrical and electronic organs necessary for the long-term operation of light-emitting diodes 7. For this purpose, the housing 2 contains an additional cavity 16 housing, inter alia, means of protection of the cards of printed circuit 6 against nuisance of electrostatic current. The cavity 16 can also contain an additional thermal filter to counter operations at unusual temperatures.

On the other hand, the kit which is the subject of the present invention comprises, in addition to the box 2, a support 17 for hanging the latter above an area to be illuminated and incorporating means for controlling the electronic circuit boards 6 and consequently light emitting diodes 7, connected to said housing 2 by a wire connection. Such a characteristic makes it possible, if necessary, to replace the control means without having to access or dismantle the housing 2.

In the illustrated embodiment, the support is defined by a mast 17 intended to be anchored to the ground, for example along a roadway, or fixed to a facade or a wall of a building. Of course, other types of supports are also possible, such as for example a cable stretched between two buildings respectively located on either side of a roadway.

The housing 2 is also connected to the mast 17 by means of a securing member 18. The latter comprises a housing 19, in the hollow of which the housing 2 is fixed, for example by means of screws screwed into tapped holes (not illustrated ) which is provided with the bottom 3 of the housing 2, the thickness of which is adapted accordingly. In the illustrated embodiment, the housing 19 is integral with a body 21 covering the bottom 3 of the housing 2 and granting the luminaire 1 a particular aesthetic appearance.

The fastening member 18 also comprises an end piece 20 secured to the housing 19 and allowing the latter to be fixed to the mast 17 by suitable assembly means. It should be noted that in the context of the invention, the fastening member 18 may have multiple forms other than those illustrated in Figure 1, each of which gives the luminaire 1 the desired design, which can advantageously be extremely refined or conversely in style, for example baroque, to meet all tastes.

Furthermore, it can also be provided to use a fastening member 180 (cf. fig. 5) having a nozzle 200 connected to a housing 190 by means of a hinge 22 making it possible to modify the orientation of the housing 190, in which is fixed the housing 2, relative to the end piece 200. Such a structure of the fastening member 180 allows, during the installation of a luminaire obtained by means of a kit according to the invention, to proceed possibly with adjustments allowing the position of the box 2 to be adjusted above the area to be lit in order to direct the lighting more precisely towards it.

As is clear from the above, the kit according to the present invention achieves the objectives set in the preamble. Indeed, each of the structural elements composing it is available in the form of an infinite range from which it can be specifically selected to compose different luminaires each time.

Thus, the housing 2 can have all the possible and imaginable forms and accommodate a variable number of printed circuit boards 6 carrying the quantity of light-emitting diodes 7 necessary for the desired lighting power.

In addition, as already indicated above, the support can be in the form of a very simple mast 17 or in any other form, and can also have as such an original aesthetic appearance or include accessories giving it such an aspect. The same applies to the joining member 18.

In other words, thanks to its three basic structural elements, the kit according to the invention makes it possible to achieve a luminaire with very modern looks, smaller and flatter than conventional luminaires. A clear and very refined form can in particular be obtained by associating a box 2 with a support reduced to its simplest structure by means of a compact fastening member devoid of bodywork. Such a shape perfectly meets the current requirements of the corresponding markets.

Furthermore, the kit according to the invention makes it possible to produce a luminaire 1 designed to operate on average around twenty years, independently of any maintenance operation. To this end, the housing 2 is equipped with means guaranteeing its sealing and inviolability, its electrical supply being effected from the outside, by means of watertight wiring produced in the factory and adapted to the configuration of the installation.
