Multi-glass for illuminating with light-emitting diode

The present invention relates to a multi-glass for light emission, and more particularly to a multi-glass for light-emitting having a light-emitting diode.

Light-emitting diodes or LEDs have been used to form illuminated indicators or attendance clocks for electrical and electronic equipment, and for several years, signal lights (indicators, side lights) or portable or pointing lights have been secured for motorcycles. The illumination of the signal device.

Recently, it has been expanded to replace incandescent halogen bulbs. The benefits of LEDs are their long life, resulting in longer maintenance of the appliances that use them, or reduced maintenance.

Document WO 2008/026170 proposes an insulating double glazing for building interior lighting, which in the embodiment of Fig. 1 comprises:

- a first glass having first and second major faces, the second face being on the inside (inner face) of the building,

- a second glass having a major surface facing the first side, called the third side, and another main surface called the fourth side, which is attached to the outer side (outer side) of the building,

- internal voids filled with hot insulating gas panels,

- a diode disposed on the inner surface of the first glass for emitting light through the first glass, but the heat is dissipated in the opposite direction by the gas plate.

Applicants have noted that the insulating glass with light-emitting diodes is not optimized for optical performance.

Accordingly, it is an object of the present invention to provide a multi-glass (especially insulating) that consistently and simultaneously emits light in an efficient, uniform and flexible manner, and preferably in accordance with industrial requirements (ease of production and speed, Reliability, etc.).

The present invention even suggests to preferably expand the range of possible applications of glass having light-emitting diodes.

To this end, the present invention first proposes a multi-glass for illuminating light having a light-emitting diode, comprising:

- the first glass, in particular the plane, preferably made of mineral glass or indeed of plexiglass, preferably having first and second major faces,

- a second glass, in particular a plane, preferably made of mineral glass or indeed of plexiglass, having a major surface facing the first side, called the third side, and another facing surface called the fourth side Main face,

- the first and second glass are secured together by a leak-proof or leak-proof peripheral attachment mechanism, and separated by an internal gap between the first and third faces, a height H (substantially) Vacuuming or filling a gas plate such as a rare gas (multiple gases) or air, and optionally including one or more spacers,

At least one first group of light-emitting diodes, each of said diodes having a predetermined visible emission spectrum, each of said diodes being disposed in an internal void and facing the first side for passage The first glass is directly illuminating in the first illuminating region, and each of the dipoles has a main emitting ray called a first predetermined main ray, directly entering the first surface without being subjected to any of the internal voids Reflection, and:

- the first illuminating region is elongated to form a illuminating strip having a predetermined width of the first and second longitudinal edges, and includes a diffusing mechanism for diffusing light emitted by the diodes associated with the first glass, Such a diode, referred to as a first diffusion mechanism, is located on the first side or in the first glass.

- each of the first set of light-emitting diodes emits a beam of light diverging and is defined by a height half angle α of at least 30° (defined according to the ray F1, an angle α of an angle α), the first main ray F1 Preferably, the first main ray F1 is substantially perpendicular to the first surface, and the light beams of the adjacent first illuminating diodes are superposed on the surface of the first diffusion mechanism, and the like The distance H1 between the diode and the first diffusion mechanism (eg, the third side) is at least 5 mm, or indeed 10 mm, and preferably less than 40 mm,

- the glass further comprises: a first diode track, located in one or more components, extending into the interior void and comprising:

a first elongate base, in particular a flat, or indeed a curved strip, in particular a rectangular or square cross section, in particular having a width smaller than the width of the illuminating strip or indeed the first diffusing mechanism, the pedestal having a first diffusing mechanism facing Directly or indirectly carrying the so-called main front faces of the diodes, in particular the front side of the first base parallel or substantially parallel to the first face (or the plane of the first glass); the first elongate side flange, Forming an optical concentrating mirror, preferably coupled to the first base, particularly a rectangular or square cross-section, preferably closer to the first side than the first base, the first flange being offset from the first base toward the first side and opposite Tilting on the first side to first receive the so-called first side ray of the first group of light-emitting diodes having an angle greater than or equal to the middle height half angle α, and returning it to the "central" area facing the first base Medium or substantially the first diffusing mechanism in the (peripheral) region further away from the first flange than the (central) region, or causing it to return (by reflection) into the face preferably having the first diffusing mechanism The area of the first glass of the first flange.

The plurality of glasses also includes a first dark region associated with the first glass (via the major faces), the first dark region being adjacent to the first light strip and offset from a surface of the first glass facing the front surface of the first base, This zone (dark zone) is not illuminated by the first set of diodes (and optionally not by other diodes or indeed by any other type of artificial light).

Therefore, preferably, the light beam does not reach the glass region corresponding to the first dark region due to the first side flange, and thereby separates the light.

The diode is positioned on the first reflector to form a longitudinally continuous strip of light. Preferably, the "in-group" distance between the first set of adjacent diodes of all the diodes is the same to simplify the overlap of the beams.

In the present invention, generally, according to a semiconductor microchip, the term "light emitting diode" (or in short, a diode) is understood to mean a quasi-needle source, generally inorganic, which is different from providing an extended light emitting surface. OLED (organic diode).

The first diffusing mechanism uniformly and simultaneously produces an illuminating region of the extended, uniform, and soft surface, and is not a group of light spots of the respective beams of the dipoles separated by the dark regions or the ambiguous regions.

In particular, the first diffusing mechanism prevents a particularly strong flash of light to people located in front of the first glass. These diffusing mechanisms modify the illuminating transmission of the first glass to make it lower. Therefore, the rays are transmitted in a small amount in a straight line with the diodes, thereby effectively reducing the flash of the individual who observes the glass.

A large enough distance between the diode (eg, microchip) and the diffusion mechanism is also fixed to help uniformity.

The beam diverges to avoid forming a brighter point (focus) between the diode and the diode. The emitted beam diverges and the redirected beam preferably diverges. Moreover, the first side flange provides a variety of good in glass:

- through the long font of the first flange, which assists in the formation of a long illuminating area without any focusing mechanism,

- by folding back the side ray, limiting the extent of the illuminating band, providing increased brightness, and better uniformity over the light area of the diode beam sprinkled on the overall surface, in the absence of focus, between Between 0 and 180°,

- by limiting the extent of the illuminating strip, which leaves or actually magnifies the adjacent functional dark areas (more central or peripheral), especially the functional areas (visible) that are different from the narrow areas of the glass rim, especially this The (large) dark areas belonging to the transparent area (glass doors, windows, compartments, etc.) are retained.

The first side flange according to the present invention can also be used to recover the backscattering of the diffusing mechanism and/or the light reflected on each side of the diode on the support of the diode (especially the PCB support of the diode). .

The first flange forming the optical concentrating mirror is preferably not a collimator. The first flange can be substantially planar or curved. The first flange is preferably substantially planar, particularly bent or curved adjacent to the first base (which is preferably planar or substantially curved) or adjacent the first base.

Preferably, the inner face (the side of the diode) of the first flange has a rectangular outline.

It may be desirable to have a number of diode tracks for the illuminating strip, but preferably the strips are sufficiently spaced to maintain a dark area or a range of dark areas.

The first base also provides several benefits of the glass according to the present invention. The diode is not directly connected to the connection circuit on the glass, but is fixed on the base of the reflector. Therefore, the diode can be tested on the reflector before being accumulated in the glass, thereby reducing the rejection rate of the multi-glass. Similarly, the base of the reflector carrying the diodes is simply removed where necessary (maintenance, color change, power change).

Placed in the internal voids, the diodes are protected from inclement weather and are especially protected from moisture.

The predetermined mid-height half angle may preferably be at least 50°, preferably at least 60°, or indeed 70°.

The emission cone can be symmetrical or asymmetrical with respect to the main ray F1. The launch cone can be, for example, a lambertian.

The primary ray F1 may be substantially perpendicular to the first face, for example, at +/- 5°. In particular, the first substantially planar planar base of the load diode may be parallel or substantially parallel to the first surface (or parallel to the plane of the first glass).

Preferably, the diffusion cone (light diffused by the diffusion mechanism) is symmetrical and is, for example, +/- 5[deg.] perpendicular to the axis of the first surface.

The design of the illuminating strip is very flexible.

A number of different light strips can be formed by a plurality of sets of diodes on the same base.

The diode rails are long and therefore longer than the width.

The first base can optionally include other sets of diodes to form another light strip, for example, in the extension of the first light strip.

In order to form a substantially different orientation of the illuminating strip, in particular the illuminating frame or the illuminating cross, a suitably shaped diode track or a plurality of diode tracks spaced or connected to one another can be used.

To be as cautious as possible and to maximize the dark area, the first diode track preferably occupies a limited space in the glass, for example, its width is only sufficient to achieve its concentrator function.

Thus, it is possible to configure the diode rail with the diode on the glass without hindering the latter - for example, the window or the facade of the building of this nature leaving the largest viewing portion and allowing all desired natural light to enter. And in the case of a plurality of diode tracks, the diode tracks can be narrow and/or wide spaced for this purpose.

The first longitudinal edge (and/or the first flange) of the first illumination strip (preferably the first diffusion mechanism) can be straight or curved.

The first illuminating strip can be straight or curved. In particular, the first illuminating strip can be particularly annular.

Preferably, if the first illuminating strip is at the periphery, the first side flange is at the farthest side of the first longitudinal edge from the center of the glass.

Preferably, the so-called "longitudinal" rays of the diode traveling along the length of the strip of light (as opposed to the side rays along the width of the strip) directly encounter the first diffused radiation (no reflection). Preferably, in particular, the diode track does not include any "vertical" walls throughout the length of the carrier diode, particularly one or a plurality of diodes.

If the first flange is short (relatively spaced from the first glass), the side ray then directly encounters the first diffusing ray outside the surface facing the first flange. In this case, preferably, a first diffusing mechanism is provided, which is also in the more edge-emitting region of the first glass. It is preferred to limit this illuminating edge region to less than 10 mm. The second flange is also true.

Preferably, the first flange comprises a first ray reflection limiting zone, usually fixed by its end, at a predetermined limit angle with respect to the main ray F1, the range of the first diffusion mechanism (facing the diode and one or more The multi-edge zone) diffuses most or substantially at least 80% or indeed even 100% of the rays having an angle less than the limiting angle by the first diffusing mechanism in the direction of the first face.

If the first reflection limiting area of the emitted radiation contacts the first side, it is of course not necessary to extend the first diffusion mechanism to the outside of the contact area.

The diode is for example located in the center of the first diffusion mechanism.

To increase uniformity, at least 80% of the so-called central ray having an angle less than or equal to the mid-height half angle α is incident on the first diffusion mechanism:

- the width of the first diffusion mechanism is such that the central ray directly hits the first diffusion mechanism,

- and / or the range of the first flange is reflected on the first flange, the central rays are incident on the first diffusion mechanism,

- and / or the rail includes a second elongate side flange, opposite the first base, opposite the first flange, preferably coupled to the first base, and the second flange is reflected in the second convex After the edge, the central rays are incident on the first diffusion mechanism.

To enhance uniformity and brightness, the rail energy can include a second elongate side flange, opposite the first base, opposite the first flange, preferably joined to the first base to form an optical poly, particularly rectangular or square cross-section The second flange is preferably offset from the base toward the first side and is preferably inclined relative to the first surface, the second flange being capable of receiving the first angle having an angle greater than or equal to the middle height half angle (α) A set of so-called second side rays of a light-emitting diode and returning it (by reflection):

- to the first diffusing mechanism in the area facing the first base,

- or to the first inclined flange (to return it to the first diffusion mechanism),

- or into the area of the first glass facing the second flange, preferably having the area of the first diffusing mechanism.

And optionally a second flange that is preferably joined to the first base forms a spacer of the first and second glass or forms part of the attachment mechanism.

This second flange can be straight due to the inclination of the first flange. This second flange presents benefits similar to those already exhibited by the first flange.

The second side flange according to the present invention can also be used to recover the backscattering and/or reflection of the diffusing mechanism on each side of the diode, such as light on the support of the diode (especially the PCB support of the diode). .

Forming the optical concentrating mirror is preferably not a collimator. The second flange can be substantially planar or curved. The second flange is preferably a substantially planar plate (metal or metallized, etc.), particularly at the junction with the first base (preferably a planar or substantially curved plate extension), or adjacent the first base Bend or bend.

Preferably, the inner face (the side of the diode) of the second flange has a rectangular outline. The second side flange is preferably closer to the first side than the first base.

The first base may carry a plurality of mutually parallel diodes on one or more supports, and all of the diodes face the first diffusion mechanism.

The "inter-group" distance between the first set of diodes and the adjacent second set of diodes can be adjusted for the overlap of the illuminating beams to form a wide continuous and preferably uniform (especially its width) Light strip.

Preferably, for good overlap of the illuminating beams, the distances within and between the groups are substantially the same to form a continuous and uniform width and length (especially over its width and at its length).

Thus, in a configuration having a plurality of rows of diodes, the first bottom carrier is aligned and parallel to the second set of diodes of the first set of light emitting diodes that are also aligned, the second set of diodes Each of the dipoles has a defined visible emission spectrum, each of the dipoles being disposed in the interior void and facing the first side to directly illuminate the first illuminating strip via the first glass, such Each of the second set of diodes has a main emitting ray F2 called a second main ray that directly strikes the first side without encountering any reflection. Preferably, the second main ray F2 is substantially perpendicular to the first The light beam emitted by each of the second set of diodes is diverged and defined by a height half angle α of at least 30°, and the second main ray F2 is incident on the first diffusion mechanism adjacent to the second The light beam of the group diode overlaps the surface of the first diffusion mechanism, and the light beams of the first group and the second group of the light emitting diodes are adjacent to the surface of the first diffusion mechanism, and the second group The distance H2 between the polar body and the first diffusion mechanism (for example, the third surface) is at least 5 mm and less than 40 m. Meter.

Moreover, the rail includes a second elongate side flange, opposite the first base, opposite the first flange, preferably coupled to the first base, forming an optical concentrator, particularly a rectangular or square cross section, the second projection Deviating from the base toward a first slope relative to the first face, the second flange being capable of receiving a so-called second side ray of the second set of light-emitting diodes having an angle greater than or equal to the mid-height angle (α) And have it wait for it to return (by reflection):

- to the first diffusion mechanism in the area facing the first base,

- or to the first inclined flange (which will cause it to return to the first diffusing mechanism),

Or entering the area of the first glass facing the second flange, preferably having the area of the first diffusion mechanism.

And preferably, for uniformity, the angle equal to the mid-height half angle α of the center of the first group of diodes and the predetermined distance L12 between the centers of the adjacent second group of diodes The first reference ray of a set of diodes is defined as tanα=L12/H1, and the second reference ray of the second set of diodes having an angle equal to the mid-height half angle α is defined as tanα=L12/H2.

In an embodiment, in order to efficiently concentrate side rays, when the value is included, the first side flange inclined with respect to the first surface is formed to be substantially constant with respect to the first surface (over all or at least throughout a majority of the range of the one side flange, a so-called deflection angle between 35 and 55°, the first flange being preferably planar (striped, parallelogram) or curved and in relation to the first The surface is inclined in the middle plane according to the so-called deflection angle.

More precisely, the first base can be flat or curved.

And when the value is included, preferably, the second flange can be offset from the first surface toward the first surface with respect to the first surface, and inclined relative to the first surface to form between 35 and 55 degrees. The so-called deflection angle, which is preferably flat (stripe, parallelogram) or curved, and is in the (main) mid-plane relative to the first face, which is inclined according to the so-called deflection angle.

In the design of the invention:

- the vertical projection of the (inner) end of the first side flange to the first face (the height of the surface of the first diffusing means) substantially corresponds to the first longitudinal edge of the light strip and the first first diffusing means,

The vertical projection of the (inner) end of the second side flange against the first face (the height of the surface of the first diffusing means) substantially corresponds to the second longitudinal edge of the light strip and the first first diffusing means.

In a simple design, the width of the first illuminating strip is substantially equal to the width of the first diffusing mechanism, thereby avoiding flashing in the direct illuminating region of the first transparent glass outside the diffusing region, and corresponding to the first and second flanges The vertical projection of the width of the surface of the first diffusion mechanism to the first glass.

A strip-shaped illuminating region having first and second predetermined limiting longitudinal edges is produced by the selection of the flange.

Preferably, to simply limit the illuminating strip and optimally concentrate the beam on the strip, the first flange and/or the second flange can extend until it contacts the first side, or until at least a gap of less than 5 mm is left. .

In an advantageous design, at least 80% of all rays are directed to the first diffusing mechanism facing the first base and the side flanges.

Efficient heat removal avoids the degradation of the efficiency of the diode and thus ensures better luminous efficiency and ensures long life of the diode.

Thus, the first base of the first diode rail can be a metal, particularly an assembly of aluminum, copper or stainless steel, forming a first thermal conductor.

In an advantageous manner, in particular substantially aligned, the first set of diodes (regular) are distributed over the first elongate common support, which is associated with the first base, in particular the printed circuit board of the strip.

The printed circuit board or PCB is in the form of a wide board or strip. It is made of plastic or metal. Often, the strip is made of metal and the board is made of plastic.

The diode support can be of any shape, such as a flat surface, in particular a straight strip such as a square or rectangular cross section. The support may be opaque because it may be masked by an opaque selected diode track.

The use of such existing support (PCB) with its connected circuitry further simplifies glass fabrication and repair and further limits scrap rates.

In particular, the first diode track of the cell may comprise a plurality of diode supports that are aligned with each other, together forming a uniform and continuous band of light or forming a distinctly different band of illumination.

The plurality of sets of diodes can be disposed on distinctly different supports including a plurality of narrow strips, or on a first common support such as an elongate printed circuit board that generally corresponds to a wider width of the base surface.

The advantage of a plurality of strips of a single PCB (supporting several sets or rows of diodes) is to reduce the manufacturing cost by optimizing the useful area for the diode configuration, and to accommodate the elastic distribution of many sets of diodes, and thus Adapting its design and ultimately reducing maintenance costs, only defective strips must be replaced.

It is known that heat removal avoids degradation of the efficiency of the diode, and thus ensures better luminous efficiency and ensures longevity of the diode.

Thus, in an advantageous manner, in particular for an average or high power diode, the first support can be fixed to a first heat conductor of the metal type, in particular aluminum, copper or stainless steel, preferably at least by the first two A first base of the polar body rail is formed, the first support accumulating heat dissipation mechanism and/or associated with a first heat dissipation mechanism coupled to the first thermal conductor.

The heat dissipation mechanism associated with and/or associated with the first support of the diodes can be comprised of a constituent material of the first support of the metal type, or a metal face that is supported by the first electrical insulation, and optionally joined The first support to the first heat conductor is formed, in particular, by a first base of the first diode rail, which performs thermal conduction adhesive tape or rubber type thermal conduction, and if the support is an electrical insulating agent, Made of electrically insulating material.

Preferably, the diode supports the metal and the diode is fused to the trace electrically isolated from the metallic material. The supporting metal material is a thermal conductor, and the support can directly resist the heat conductor to obtain heat dissipation.

The attachment of the support to the base can be fixed, for example, by clamping and/or screwing. Thermal conductors (such as thermal grease, hot adhesive tape and/or hot glue, etc.) can be inserted for better heat dissipation, for better luminous efficiency and for the longevity of the diode.

Adhesive tape presents the advantage of providing a calibrated thickness that allows for the support of a perfect plane and ensures that the diodes are equidistant from the reflector. Moreover, the adhesive tape allows it to be fixed to the support in advance.

The diode support is preferably mounted via a double-sided adhesive or curable glue (which does not provide immediate fixation) because it allows the support of a small size to be relatively positioned on the reflector.

Supported by a plastic diode, the diode is fused to a heat dissipating surface (referred to as a "heat pad") that is added to the opposite side of the support and traverses its thickness. The fixing must be carried out via an electrically insulating material for joining the thermal conductors associated with the heat dissipating surface. The material for bonding the heat conductor is, for example, a rubber or heat-conductive double-sided adhesive tape which has been cited.

For better luminous efficiency, the first support can be loaded with a free surface (planar or slanted) around the first set of diodes and, for example, diffused varnish or lacquer. For example, a white reflector is used.

According to one feature, the diodes can be packaged, and can include semiconductor microchips and, for example, epoxy or PMMA type resins for encapsulating the microchips. This package is versatile: protection against oxidation and humidity, conversion of wavelength diffusing elements, etc. The diode can be buried in a common protective material (waterproof, dustproof, etc.).

The diodes can be, for example, semiconductor microchips of the order of hundreds of microns or millimeters; and optionally have, for example, a minimum package for protection. It is not necessary to use an optical product such as a lens to guide the light emitted by the diode toward the favorite area.

Therefore, preferably, the diode may be a simple microchip or have a low-capacity package such as an SMD ("surface mount device") or a "wafer direct mount circuit board" type, rather than a low power and luminous efficiency. Know the (first generation) diode.

Preferably, the diode can be:

- "Medium Power" diodes, ie greater than 0.1W or having a brightness greater than or equal to 8 lumens,

- "High Power" diodes, ie greater than or equal to 1 W or having a brightness greater than or equal to 80 lumens.

The diode may preferably have a luminous efficiency of at least 40 lm/W (lumens per watt), or indeed at least 60 lm/W (lumens per watt).

The luminescence can be illuminated in particular according to a total luminous efficiency of at least 40 lm/W (lumens/watt). The optical efficiency of the luminescent glass (ratio of total efficiency to diode efficiency) can be greater than 70%.

From the point of view of size, at least one of the characteristics of the following diodes can be foreseen:

- the diode is less than 1 cm in height, or actually less than 5 cm,

- the diode is less than 1 cm (diameter) in width,

- the diodes are identical and regularly spaced apart by a distance within the group representing the distance between the axes of the continuous diodes, optionally in the same level as the inherent diode size,

- the first set of diodes are aligned and regularly spaced apart by a distance within the group representing the distance between the axes of the continuous diodes, the second set of diodes representing the distance between the axes of the adjacent two diodes, For example, the distance between groups in the same level as the distance within the group, parallel to the first group, aligned and regularly spaced,

- The number of the first set of diodes is at least equal to 10.

The sturdiness of the diode is particularly advantageous in large-scale use such as public transportation such as trains, airplanes, buses, cruise ships, and the like.

One or more sets of diodes can be coupled to the drive mechanism to impart a variety of different intensities, predetermined colors or various colors of light, either permanently or intermittently, particularly depending on the amount of natural light.

The first diode track according to the invention may be a monomer, in particular a metal or a dual material.

The first base and/or the first flange and/or the optional second flange can comprise a substrate (preferably mineral):

- for example, coating a reflective layer (mirror reflection or diffuse reflection),

- coating a shiny metal layer (especially a mirror reflection with a reflection coefficient greater than or equal to 70% or indeed 80%) or a matte layer (diffuse reflection),

The so-called deflection angle, in particular metal or metallized, planar or concave, forms part of the joining mechanism defining the internal void, optionally with respect to the first face when it is equivalent to the first face Tilting preferably forms a so-called deflection angle between 35 and 55 degrees.

Moreover, for the sake of caution, the vertical projection of the first face and/or the second flange to the first face may be selected to be less than or equal to 4 cm, and preferably less than or equal to 2 cm.

The first base can be placed apart or against the glass. Optionally, the first diode track has a surface for supporting or actually securing to the third face.

The first diode track can be secured to the second glass, or indeed another element in the internal void, by screwing, clamping type mechanical attachment or by pasting.

In an embodiment, the first light strip is curved, in particular annular, and the first base and the first flange are also curved.

From the point of view of size, at least one of the following characteristics of the diode can be foreseen:

- The glass is mechanically strong, making it easy to clean and not scratching, thereby demonstrating the special benefits of using glass that is strictly required for installation and positioning.

The examples will now be explained by way of illustration only, and without limiting the scope of the invention,

Fig. 1 is a view schematically showing a multi-glass 100 for illuminating light having a light-emitting diode in an embodiment of the present invention.

The glass 100 is an insulating glass here, including:

- a first glass 1, made of mineral glass, for example a square or rectangular glass plate, having first and second major faces 11, 12;

- a second glass 1', for example a square or rectangular glass plate, having a major face facing the first face, referred to as the third face 11', and a facing major face called the fourth face 12',

- the first and second glasses 1, 1 ' are secured together by a peripheral joining mechanism 5 in the form of a butyl 51 on the surface of the glass and containing a desiccant 52 and surrounded by a mastic resin seal 5' a peripheral leakage preventing system 5 in the form of a metal frame, the first and second glass being separated by an internal space 13 between the first and third main faces 11, 11', which is filled with a gas such as a rare gas (multiple gases) or air Gas plate,

- a first group of inorganic light-emitting diodes 2 (or LEDs), disposed along the first longitudinal edge of the glass 100, disposed in the internal voids, the diodes aligned and regularly distributed in the strip-shaped first elongated PCB diode Support 20,

a second set of phosphor II (or LED) along the first longitudinal edge of the glass 100, the diodes being aligned and regularly distributed over the strip of the second elongate PCB diode support 20.

Each of the diodes 2 has a predetermined visible emission spectrum, such as white light, having a primary emission ray F1 called the first primary ray that directly enters the first face 11 without encountering any reflection, such as a substantially vertical ray F1. On the first side 11. To be more concise, the set of diodes is selected in the same main (single) emission direction. For uniform illumination, one diode of the same group is selected in the same spectrum, single color or multiple colors. The emission cone can be symmetrical or asymmetrical with respect to F. The launch cone can be, for example, a lambertian. The beams of the dipoles diverge and are defined by a height half angle a of at least 60°.

The diode 2 is of the SMD type or the CHIP ON BOARD type. The first and second PCB supports 20 are, in particular, metal straight strips of aluminum, and optionally have a diffusing surface for radiation recovery (not shown) around the diodes 2.

Each set of diodes 2 is configured to emit light through the first glass 1 at the peripheral light strip 40, having a predetermined width, and including a diffusion mechanism 4 called a first diffusion mechanism throughout the entire width for diffusion and first Light emitted by the glass-related diode 2.

A first perimeter illumination strip 40 associated with the first set of diodes is along a first longitudinal edge of the glass 100. Another first peripheral illumination strip 40 is associated with a second set of diodes along a second longitudinal edge of the glass 100.

The first main ray F1 is incident on the first diffusion mechanism. The beams of the adjacent first set of diodes overlap the surface of the first diffusing mechanism.

The first diffusion mechanism 4 is capable of modifying the illuminating transmission of the glass 1, for example between 40 and 85%. The diffusing mechanism 4 prevents excessive transmission of the illuminating rays emitted by the diodes, and greatly reduces the flash for individuals viewing the glass 100.

The diffusion mechanism 4 on the face 11 of the glass is obtained by: - by means of a glass sanding or acidification treatment of Satinovo® glass from SAINT-GOBAIN GLASS, or as a variant, by way of a variant Adding, for example, 珐琅 and by screen printing The diffusion layer obtained, or the diffusion layer of glass Smoothlite® glass with diffusion layer from SAINT-GOBAIN GLASS, screen printing has the advantage of being able to obtain any type of design with well-defined boundaries, or as A variation, in the thickness of the glass, is by laser etching.

In another variation, when the glass 1 is laminated with additional glass via the intermediate layer, the diffusion mechanism is constructed by designing a diffusion plastic intermediate layer.

Here, the two first lighting strips 40 are straight (as shown in Figure 1c), each having a first longitudinal edge 41 and a second longitudinal edge 42.

Of course, the two first light strips 40 may be identical or different in shape, width, color, properties (different diffusing mechanisms, etc.).

The width of each of the first illuminating strips 40 is, for example, less than 200 mm or substantially less than 100 mm.

On the first glass 1, the first dark zone 60 (i.e., the center zone), which is preferably wider than the light-emitting strip, separates the first light-emitting strips 40. Here, this is the first dark region 60 (i.e., the transparent region) of the first glass 1 preferably facing the second dark region 60' of the second glass 1' (i.e., the transparent region). As a variant, by means of the addition of several layers, it forms a reflective, decorative or translucent area of the mirror.

For each set of diodes 2, the glass 100 in turn comprises a first diode track 3 in the internal void 13 which is a metal monolithic component, for example made of aluminized aluminum and having a thickness of less than or equal to 3 mm. , with two bends or bends.

Each of the diode rails 3 (shown in a perspective view of FIG. 1b) includes: - a first elongate planar base 30 having a smaller width than the first diffusing mechanism 4, the base having a first diffusing mechanism facing the first diffusing mechanism 4 and the main front side of the support 20 carrying the diodes 2, the support 20 is centered on the diffusion mechanism 4;

- and on each side of the first base, to the first base:

a first elongate side flange 31 forming an optical concentrating mirror, having a planar and rectangular cross section, the first flange 31 being offset from the first base toward the first side and inclined relative to the first surface to first receive an angle greater than or Waiting for the so-called first side ray R1 of the first group of light-emitting diodes of the middle height half angle α, and returning it to:

- facing the area having the first diffusing mechanism, or reflecting it on the area facing the first flange having the first diffusing mechanism,

a second elongate side flange 32, opposite the first base, facing the first flange, having a flat and rectangular cross-section, wherein the second flange 32 is offset from the base 30 by being inclined relative to the first surface And facing the first side, to receive the so-called second side ray R2 of the first group of light-emitting diodes having an angle greater than or equal to the middle height half angle α, and returning it to:

- facing the area with the first diffusion mechanism,

- towards the first inclined flange,

- facing the area of the second flange with the first diffusing mechanism.

Accordingly, in a simple manner, with respect to each of the diode rails 3:

- the first base 30 is flat and has a smaller width than the width of the first diffusing mechanism 4,

- the first elongate side flange 31, inclined relative to the first face, forming a so-called deflection angle of 45° with respect to the first face 11

The second planar side flange 32 is offset from the front surface of the first base 30 toward the first surface 11 and is inclined with respect to the first surface to form a so-called deflection angle of 45° with respect to the first surface 11.

Therefore, the cross section of each rail is flared U-shaped. Each of the diode rails 3 has a surface for supporting or actually being fixed to the third face 11' or, as a variant, spaced apart from the third face.

The first flange 31 and the second flange 32 extend until contact with the first face 11 or until a gap of less than 5 mm is left at the maximum to redirect the largest portion of the side ray.

The width of the first light strip 40 is substantially equal to the width of the first diffusing mechanism 4 and corresponds to the vertical projection of the width of the first and second flanges 31, 32 with respect to the first glass 1.

The diode 2 is fused to traces that are electrically insulated from the material of the associated PCB support 20. The supporting metal material is a heat conductor, and the support can directly resist the first base which is itself a heat conductor to obtain heat dissipation. The support can then be fixed to the base, for example by clamping and/or screwing.

Here, a heat conductor bonding material 21 such as a glue or a double-sided adhesive tape is inserted to obtain better heat dissipation.

The adhesive tape 21 is presented to provide a calibrated thickness, allowing the support 20 of the diode 2 to be a perfect plane and to ensure that the diodes are all equidistant from the first glass 1. Moreover, the adhesive tape allows it to be fixed to the support 20 in advance. It is also preferable to use CK4960 such as sold by Jetart. The thermal grease of the compound is between the support and the first base 30.

Preferably, a masking mechanism 6 for masking the so-called back of the first base 30 or actually masking the first flange 31 and the second flange 32 is added to each of the diode rails 3. For example, this is a masking mechanism 6 in the form of a reflective layer forming a mirror, for example a colored decorative layer, in particular a second glass (1') (screen printing, etc.) or a matte.

For each of the diode rails 3, it is preferred to add so-called front masking mechanisms 61, 62 for the ends of the first flange 31 or indeed the second flange 32 to the first face 11 (or as a variation) For example, to the second side or to the additional glass associated with the second side, the mechanism is selected from the group consisting of a reflective layer forming a mirror, a diffusing region of the first glass, in particular a matte, in particular a color and preferably a first diffusing mechanism A decorative layer of the same type, or a selected mirror reflection, translucent or decorative dark area.

For example, the diffusion zone can be extended outside the illumination zone.

The dimensions of the various components are as follows: - The area of the glass is 600 x 600 mm, and the double glazing of the ultra clear glass is 2.9 mm thick, - the height of the internal gap is 28 mm, - the first light strip The width is 40 mm, and the length of each first light strip 40 is 550 mm, - the central dark area is about 400 mm, - each support carries 30 diodes, 10 mm wide, 550 mm long, and has a thickness of 1.9 mm. Class, and - diode, no optics, height 2 mm, width less than 6 mm, regular distance between diodes 2 is 18 mm, - the distance between the diode and the first diffusion mechanism is 20 mm , - The diode has an individual power of (about) 0.3W, at least 40lm/W (Lumen/Watt) efficiency, - The width of the first base is 15 mm.

Luminescence can be illuminated, in particular, based on a total luminous efficiency of at least 40 lm/W and an optical efficiency of greater than 70% (ratio of total efficiency to diode efficiency - lumens per watt) while being uniform and exhibiting very little flash.

The efficiency is measured in an ordinary manner by means of a goniometer and at room temperature. The thermal conductivity of the base, the diode support, and the mechanism for supporting the base are such that the heat released by the LED is dissipated and contributes to luminous efficiency.

Therefore, it can be formed: - for architectural purposes, illuminating building facades, illuminating windows, ceiling lights, illuminating floors or wall tiles, illuminating glass doors, illuminating compartments, stairs, - for use in transportation vehicles, illuminating side glazing or glazing Roofs, illuminated windows, illuminated glass doors, especially public transportation, trains, subways, trams, buses or water or airborne vehicles (airplanes), for road or city lighting applications, in urban furniture, bus shelters , railings, display stands, window displays, illuminating glass parts of greenhouses, illuminating glass parts of shelves, - for interior decoration purposes, the luminous wall of the bathroom, the illuminating glass part of the furniture project, the glass wall of the refrigerating project of the equipment Cover, glass door, shelf, etc.).

The first glass 1 faces, for example, after installation.

Each glass can be covered with a different shape such as a rectangle, a square, a circle, or any other geometric shape as desired.

Each glass exhibits at least 85% high luminescence transmission. For example, it may be based in particular on the aesthetic display or the desired optical effect and/or the use of multiple glasses: - standard composition glass, such as Planilux® micro green tinted glass from SAINT-GOBAIN GLASS, - colorless (medium Super clear glass, like Diamant® glass from SAINT-GOBAIN GLASS, - pyramidal printing glass, like Albarino® glass from SAINT-GOBAIN GLASS, in the form of a relief made of pyramids in the face of the external environment The outer surface of the glass, - toughened glass, exhibits better mechanical strength.

Figure 1d is a schematic rear view of a generally cruciform metal plate intended to form another diode track 3, which according to the invention can be integrated into a luminescent multi-glass having a light-emitting diode.

The dashed line indicates the bend zone 32' to form a first cross-shaped base, and by adding the cut-out zone 32', the first side flange 31 and the second side flange 32 are formed on each side of the first base and joined to the base.

Figure 1e is a schematic front view of a diode track obtained from the plate of Figure 1d.

To simplify the layout, there is a first vertical PCB strip 20 loaded with a first set of diodes 2, and on each side of the strip there are two horizontal PCB strips 20 loaded with other sets of diodes 2.

Figure 1f is a schematic diagram taken from the top of the glass of Figure 1e (first The glass side) displays a cross-shaped central illuminating strip 40 and a peripherally adjacent first dark region 60, for example transparent.

The 1 gth diagram is a schematic front view of another diode track in which a light-emitting multi-glass having a light-emitting diode according to the present invention is integrated.

The diode track 3 is generally annular and has a first annular base and first and second flanges joined to the base.

The 1h figure is a partial perspective view of the dipole track of the 1st diagram, showing that the cross section of the rail is a flared U-shaped type.

Figure 1i is a schematic view (first glass side) taken from above the glass having the track of Figure 1g, showing the annular central light strip 40 and a first dark region 60, for example, transparent adjacent to the center.

Fig. 2a is a cross-sectional view showing a multi-glass 200 having a light-emitting diode in a second embodiment of the present invention.

Only the differences from the glass 100 will be described.

The glass 200 differs from the glass 100 in particular in that: - a single diode track 3 having a single first light strip 40 selected in the center and having a first perimeter of the two dark areas 60 (ie, transparent) Zones, - are side by side with the first PCB support of the diode 2a, and the second PCB support of the diode 2b is added to the first base 30.

In the second set of diodes, each of the diodes 2 has a predetermined visible emission spectrum, such as white light, and has a main emission called a second main ray that directly enters the first side 11 without encountering any reflection. The ray F2, the ray F2 is substantially perpendicular to the first face 11.

The emission cone can be symmetrical or asymmetrical with respect to F. The launch cone can be, for example, a lambertian. The beams of the dipoles diverge and are defined by a height half angle α of 60°.

In the second group of diodes, the diode 2 is also of the SMD type or the CHIP ON BOARD type, and the PCB support 20 is also a straight metal strip of aluminum, and optionally A diffusing surface for radiation recovery (not shown) is provided around the diode 2.

To be simpler, the set of diodes is selected in the same direction (single) as ray F2 and F1.

For uniform illumination, two sets of diodes are selected in the same spectrum, single or multiple colors, and the same radiation cone.

The second flange receives a so-called second side ray (R4) of the second set of diodes (2b) having an angle greater than or equal to the middle height half angle (α) and returns it (by reflection): - to the surface The first diffusing mechanism (4) in the region of the first base (30), or to the first oblique flange (31) (which will cause it to return to the first diffusing mechanism), or into the first glass ( 1) A region facing the second flange (32) having a first diffusion mechanism.

And for a predetermined distance L12 between the center of the first set of diodes 2a and the center of the adjacent second set of diodes 2b, the first set of angles is equal to the middle height half angle α and advances toward the second flange A reference ray is defined as tanα=L12/H1, and the second set of angles is equal to the middle height half angle α and is toward the first The second reference ray advancing the flange is defined as tan α = L12 / H2, and the distance H2 between the second set of diodes and the first diffusion mechanism is equal to, for example, H1.

From the dimensional point of view, the width of the first base 30 is increased to 30 mm, and the "inter-group" distance between the adjacent diodes 2a and 2b of the two 20s is 13 mm.

Here, the first diffusion mechanism is a diffusion layer.

Moreover, the joining mechanism has been optically simplified into, for example, a single metal frame to form a compartment.

Figure 2b is a partial schematic perspective view of the diode rail of the glass 200 having two diode supports 2a, 2b of Figure 2a.

Fig. 2c is a schematic view taken from the top of the glass 200 of Fig. 2a (the first glass 1 side); the central light emitting region 40 and the peripheral first dark region 60 (i.e., the transparent region) are shown.

3 to 7 are schematic cross-sectional views showing a plurality of glasses 300 to 700 having light emitting diodes in other embodiments of the present invention.

It is stated that the only difference in the glass that has been illustrated is that.

The glass 300 shown in Fig. 3 differs from the glass 200 in that the two-metal PCB support 20 is replaced by a single support of a plastic PCB.

The diode is welded to the heat dissipation surface 22 (referred to as a thermal pad) added to the two opposing faces 22a and 22c of the board, and is welded in the emergency hole 22 according to the thickness 22b thereof.

For heat removal, the plate 20 is secured by a heat guide joining material 21 associated with the heat dissipating surface 22c and which must be an electrical insulator.

The diffusion mechanism 4 is made by acidifying the first face 11.

The glass 400 shown in Fig. 4 differs from the glass 200 in the double U shape of the rail 3, which thus has a second base 30' and third and fourth side flanges 31', 32'. The masking mechanism 6' of the base 30' is a decorative layer.

The glass 500 shown in FIG. 5 is different from the glass 100 in that the second glass 1' includes a second light-emitting strip 40' facing the first light-emitting strip 40, and the second diffusing mechanism 4 is associated with the second glass 1'. In particular, it is substantially the same as the first diffusion mechanism 4.

The first diode track 3 is movable and spaced sufficiently from the glass to rotate about an axis parallel to the first glass 1.

In the first position, the first set of diodes 2 illuminate the first light strip 40.

In the second position, the front surface of the first base 30 faces the second diffusion mechanism 4, the first group of diodes illuminate the second light strip 40', and the first flange 31 forms an optical aggregate for the second light strip Light.

The first dark region 60 associated with the first glass forms a mirror on the first face 11 by depositing silver, for example.

The second dark region 60' associated with the second glass 1' and facing the first dark region 60 forms a mirror, for example, by depositing silver on the first face 11'.

The glass 600 shown in FIG. 6 is different from the glass 100 in that: - the second glass 1' includes a second light-emitting strip 40' facing the first light-emitting strip 40 and associated with the second glass 1', and the second diffusion mechanism 4 Corresponding to the second glass 1', in particular substantially the same width as the first diffusion means 4, - the other set of diodes 2 on the metal PCB strip 20 illuminate the second illumination strip 40', - in particular similar to the first The second diode track of the diode track includes Forming a second base behind the first base and carrying the other set of diodes 2, and particularly two side flanges similar to the side flanges 31, 32, forming a second light strip 40' Optical concentrator.

To configure this two rails, its height increases.

The glass 700 shown in FIG. 7 is different from the glass 100 in that the second glass 1' includes a second light-emitting strip 40' that is offset from the first peripheral light-emitting strip 40 and associated with the second glass 1', and the second diffusion mechanism 4 is The second glass 1' is associated with and deviates from the first diffusion mechanism 4.

The plurality of sets of diodes 2' illuminate the second illuminating strip 40'.

Each of the first diode rails 3 has an extension portion including: - another base 30' mounted on the front surface of the other group, particularly 2', and coupled to the first side flange 31, the first The side flange has an optical concentrator that faces the front side (which encounters the side ray R1 of the first set of diodes 2), forms a beam of rays emitted by the other set of diodes 2', and the other side convex The rim 31', similar to the first side flange 31, also forms an optical concentrator for the radiation emitted by the other set of diodes 2'.

The first dark region 60 (i.e., the central dark region) forms a masking mechanism 6 (i.e., as a reflective layer of the mirror) deposited on the first side, including facing the other side facing the front side having the diode 2' At least one surface behind the base 30' to mask the rail.

The second dark region 60' (i.e., the central dark region) associated with the second glass 1' also forms a masking mechanism 6' (i.e., as a reflective layer of the mirror) and is deposited on the third face 11'.

Preferably, for this application, the diffusion mechanism 4 is obtained by sanding the masking mechanism 6, 6' (i.e., the reflective layer) forming the mirror to simplify manufacturing.

This glass is for example a compartment.
