Definitions
- the present invention relates to vehicle glazings, and in particular to light-emitting diode glazings.
- LEDs in English or LEDs in French More and more vehicles use light emitting diodes (LEDs in English or LEDs in French).
- WO2006128941 proposes for example a panoramic roof with homogeneous illumination on the surface by diode (s) electroluminescent (s).
- This roof has a laminated structure which is composed of an outer sheet extracting light, a transparent central light guiding sheet, and an inner sheet of light diffusion.
- a support of a light guide is a C-section profile on the perimeter of the laminated structure, the light guide being connected to a diode at its end.
- This structure is complex and lacks compactness.
- the light-emitting diodes are mounted on a lateral support which is a section of rectangular section fixed to the edge of the inner and outer leaves while a hole is made in the central sheet to house the diodes.
- the invention proposes to design an alternating light emitting diode module which is reliable, at least with a controlled light injection, which is robust and compact while remaining simple to achieve and mount.
- the present invention also aims a diode module satisfying the industrial requirements (in terms of efficiency, so cost, cadence, automation %), thus making a production "low cost” without sacrificing performance.
- the present invention proposes a light-emitting diode module for a vehicle comprising:
- a glazing unit with main faces comprising at least a first curved transparent sheet having a first main face and a second main face and a wafer, light-emitting diodes each comprising an emitter chip capable of emitting one or more visible and guided radiation (s) in the first sheet after injection by the wafer (perforated or not) or by the lateral face opposite hole (s) in one of the first or second main faces and housing the diodes, guidance before extraction via at least one of the first and / or second faces,
- a support section for the diodes at the edge of the glazing unit comprising a glass fixing clip with a so-called median part, a first discontinuous wing and a second discontinuous wing,
- the first wing having a first series of tabs for fixing and / or centering the clip spaced apart from each other
- the second wing having a second series of tabs for fixing the clip (or even centering as well) spaced apart from one another, the first and / or second series of tabs thus forming means for holding the diodes in vertical positions (ie position according to FIG. vertical axis at the mean plane of the glazing) predetermined with respect to the first sheet, this independently of the curve and any curve variations.
- the injection of the light emitted by all the diodes is perfectly controlled thanks to the adapted mounting bracket.
- the chips are not necessarily aligned with each other. It suffices (at least) that they remain in front of the optical coupling zone with the first sheet, which is therefore the slice or the lateral face of hole (s).
- the radii of curvature can be very varied. For roofs, they vary for example between 2000 and 6000 mm. For glasses, they can be very variable, for example from 200 to 6000 mm. On smaller panes of the quarter panel type, the radius of curvature can vary from 150 mm locally to 2000 mm.
- the radii of curvature may be of the same order or less than the radii of curvature of the mineral glass.
- the radius of curvature is for example of the order of 100 mm with abrupt variations of radii of curvature.
- Shape tolerances vary depending on the size and manufacturing process of the glazing. For example, on a side glass of mineral glass, the curve tolerances at 5 mm from the edge of the glass are generally of the order of +/- 0.5 to +/- 1.5 mm. In the case of roofs, the tolerances oscillate between +/- 0.5 and +/- 2.5 mm depending on size and process.
- the curve tolerances may be of the same order as the mineral glass or slightly lower depending on glazing control methods taking into account the flexibility of the plastic (depending on the number of reference points and / or clamping, the vertical or horizontal orientation of the glazing during the inspection, ..)
- the number and position of the legs of the first series and / or the second series will depend on the number of diodes, the space between each diode and the curve.
- At least one fixing lug and / or centering is in a plane transverse to the glazing, in particular, as a function of the mounting of the diodes, transverse plane to the mean plane of the glazing or the edge of the glazing and / or to the lateral face facing said housing hole of the diodes, said plane passing through said diode or the diode group, in particular by a diode of said group (center of the group for example).
- the total number of diodes is defined by the size and location of the areas to be illuminated, by the desired light intensity and the required light homogeneity.
- the spacing between the legs of the same series is a function of the number and size of diodes and the curve and the fact that the legs of the two series are opposite or offset (larger spacing then possible). It can therefore vary typically between 20 mm and 250 mm.
- the length of the fixing and / or centering lugs may vary from 3 to 30 mm.
- the width of the fixing and / or centering lugs may vary from 2 to 30 mm.
- the legs of the same series can be identical.
- the legs of the same series can be aligned with each other.
- the legs of the two series may be identical.
- the legs of two series can be opposite or staggered.
- the cross section of the fastening clip is variable and for example:
- the fixing lugs have, preferably at their ends, clipping portions.
- the longitudinal section of the clipping ends can be relatively free: for example rectangular, trapezoidal, triangular, T ...
- the cross section of the clipping ends can be preferably curved.
- the module comprises a polymeric encapsulation, particularly thick from 0.5 mm to several cm, located at the edge of the glazing and covering all or part of the diode support profile, and preferably sealing means to the material. liquid encapsulation injected at a given temperature and pressure.
- the encapsulating material is black or colored (for aesthetic and / or masking purposes). Since the material is not sufficiently transparent to the visible radiation (s), sealing is necessary to ensure a good injection of light into the first sheet.
- the encapsulation may be polyurethane, especially PU-RIM (reaction in mold in English), the crosslinking of the two-component PU operating in the mold, once the two components injected simultaneously.
- This material is typically injected up to 130 0 C and a few tens of bars.
- encapsulating materials are: preferably thermoplastic elastomeric thermoplastic (TPE), polyvinyl chlorine (PVC), ethylene-propylene-diene terpolymer (EPDM), typically injected between 160 ° C. and 240 ° C. and at 100 bars,
- TPE thermoplastic elastomeric thermoplastic
- PVC polyvinyl chlorine
- EPDM ethylene-propylene-diene terpolymer
- PC polycarbonate
- PMMA polymethylmethacrylate
- PE polyethylene
- PP polypropylene
- PA66 polyamide
- ABSPC acrylonitrile butadiene styrene
- PU internal or external
- silicone silicone
- acrylic acrylic
- thermoplastic resin PVB, EVA ... (internal or external).
- the encapsulation may form additional sealing means, for example more effective in the long term possibly via a layer of primer, mono, bi or tri-components, for example based on polyurethane, polyester, polyvinyl acetate, isocyanate
- silicone adhesives in the case of encapsulation on mineral glass, it may be preferable to prohibit silicone adhesives as an external adhesive, because they adhere very well to the glass but will prevent the adhesion of the encapsulated material to the glass.
- Encapsulation also brings a good aesthetic finish and allows to integrate other elements or functions:
- the encapsulation can be of any form, with or without lip, biface, triface.
- a tubing in other words a closed cell sealing profile, can also be attached to the encapsulation.
- Sealing means can be useful at several levels: o at the time of manufacture of the module, as described previously o in the long term, for example 5 years, especially for a protection against the humidity of chips (liquid water, steam), to avoid pollution of space emitted radiation
- the standard D47 1165-H7 used in the automobile describes the test of wet poultice H7.
- This test involves drowning the test piece in cotton soaked in demineralised water and enclosing it in an airtight bag, then placing it in an oven at 65 ° C for 7 days. Then the pieces are removed, stripped cotton soaked and placed at 20 0 C for 2 hours. Parts can finally be observed and tested mechanically or functionally to evaluate the effect of moisture on the system.
- This test corresponds to several years of natural aging in a humid and hot environment.
- a high-pressure water jet cleaning test such as the washing resistance test using a D25 5376 high pressure washer used in the automobile: pressure up to 100 bar with a nozzle / box distance up to 100 mm.
- Sealing means for the fluid (s) may be chosen from: an adhesive, said external placed on the surface of the support of the diodes, opposite the surface facing the glazing, and protruding on the periphery of the glazing, possibly forming all or part of the means for fixing the support to the glazing,
- Adhesive tape optionally an enveloping strip with a covering portion on the support extended by the projecting parts
- an adhesive material for filling the radiation space emitted transparent to said radiation preferably an adhesive, a thermoplastic resin, a double-sided adhesive,
- the external adhesive may be an adhesive tape: - monolithic, common to all the diodes, - or in pieces, by diodes or group (s) of diodes.
- the strip is fixed at the periphery of the glazing, by the edge of the glazing and / or by one or more main faces of the glazing.
- the so-called band then enveloping, can completely cover the support by lower and upper parts and side parts.
- the band is of dimensions (width and length) greater than the dimensions of the emergent portion of the diode support.
- the strip may also cover only the support with lower and upper parts and not the side parts (or sides) of the support profile. To facilitate the passage of the connectors, we can make through holes in the band.
- the lateral parts (or sides) of the support profile are sealed to the (s) (encapsulation and / or long-term) fluid (s) by "localized” adhesive means such as those already described. : glue, resin etc.
- connection passes between the support and the glazing, we can make through holes in the adhesive.
- the adhesive strip may comprise a rigid core (metal %) protruding from the edge of the strip and not covered, to facilitate tearing the tape at the time of repairing the vehicle or changing diodes ...
- the adhesive material for protecting the chips transparent to said radiation (s) is identical to the filling material and is chosen from:
- the space of the emitted radiation varies naturally according to the radiation pattern of the chips, defined by a main direction of emission and a cone of emission.
- the complete space between the wafer and the chips (pre-encapsulated or not), and possibly bounded by one or more wings of the support, is filled by the adhesive material.
- the module comprises a pre-assembled polymeric seal, for example made of elastomer, especially TPE (for thermoplastic elastomer), or EPDM, a few mm thick (typically between 2 and 15 mm).
- the seal may possibly form the mounting support section to the glazing (the diodes may be on a base added and fixed to the support, for example of rectangular cross section), or the seal covering all or part of the support profile of the diodes.
- the seal can be adhesive for its maintenance.
- the U-shaped seal can more preferably simply hold by pinching or donning the two main faces of the glazing.
- the seal can be of any form: in L, in U ...
- the seal can carry the diodes and the base or strip carrying the diodes (of rectangular section for example).
- the seal (associated with the base) can form here the mounting bracket to the glazing.
- the seal may comprise a metal core.
- the seal can be dismountable at any time. It can nevertheless form additional sealing means, for example (more) effective in the long term possibly by one or more of the lips of the elastomer seal stressed after fixing.
- the elastomer in particular EPDM, has a sealing function and good properties of compression remanence.
- the sealing means used are preferably between the seal and the periphery of the glazing.
- the support can be attached to the glazing before mounting the seal, the seal is then mounted by all existing means (clamping the U-shaped support, gluing by means of a double-sided adhesive ).
- the seal with the diodes can be preferably mounted in an assembly operation, with a single translational movement (by pinching, shoes ).
- EVA ethylene / vinyl acetate copolymer
- PVB polyvinyl butyral
- a double-sided adhesive transparent internally
- single-sided externally
- an adhesive transparent if in-house
- the middle part is extended on either side by the first and second wings which are on the side of the second main face, the profile comprising a carrier portion of the diodes separate and secured to the fastening clip, the second face is coated (at least) at the edge of a so-called holding layer with at least one recess for fixing and / or centering the fastening clip.
- the holding layer preferably rigid or semi-rigid (for better centering and / or fixing accuracy) can be:
- a masking layer black or colored, for example a polymeric layer, in particular a polycarbonate layer on a first polycarbonate sheet, an overmolded layer, for example a layer of encapsulation material (such as that already described above, and possibly incorporating one or more module attachment inserts and / or reinforcement as already described above).
- the retaining layer may be of minimum thickness equal to 1 mm to 20 mm.
- the retaining layer may be bonded to the first sheet by an adhesive.
- the support can be thus defined:
- the first and second wings are longitudinal, that is to say extending substantially parallel to the mean plane of the first leaf, the first wing being closer to the second face than the second wing,
- each leg of the second series carries a so-called clipping end (preferably rounded) housed in a recess of the free main surface, said clipping recess, wider than the width of the end clipping,
- the length of the clipping lugs is greater than the length of the centering lugs
- the legs of the second wing are spaced from the free surface, or housed in one or more (s) of the main free surface.
- the clipping ends may be aligned or staggered, with each other and with the centering tabs.
- the centering recess can be individual (specific to each leg) or common to several (all) centering tabs. This obviously centering can be:
- the centering and / or clipping lugs may be of preferably straight cross section, in particular rectangular (excluding clipping ends).
- the centering and / or clipping lugs may be substantially planar (excluding clipping ends).
- the medial portion may be preferably spaced apart from the holding layer and substantially flat or curved.
- the carrying part of the diodes can be substantially flat.
- the profile can be of constant thickness.
- the middle portion (and the integral carrier portion) of the diode support is preformed with a curvature substantially equal to the nominal curvature of the glazing.
- the centering tabs can then be based on:
- the curve is greater than the nominal curve.
- the median part of the support (and the solidarity carrier part) is flat and flexible before mounting on the glazing and elastically deformed during its assembly, thus becoming curved according to the curve of the glazing (at least) at the level of the fixing zones by the legs.
- the centering tabs rest on the longitudinal face of the recess furthest from the second face. On the sides of the support, the centering tabs rest on the longitudinal face of the recess closest to the second face (or even on the second face if necessary).
