Light-emitting diode assembly for vehicles
An assembly includes a glazing with an interior glass sheet having a through hole, an exterior glass sheet, and at least one intermediate plastic layer; a light-emitting diode module with a light emitting diode having an illuminating part, and a base; a support plate fixed to a face of the interior glass sheet opposite the at least one intermediate plastic layer, the support plate including several lugs extending away from the interior glass sheet and a spring element. The illuminating part is positioned in the through hole, with the base retained by the lugs, and pressed against the glazing by the spring elements.
1. An assembly for vehicles, the assembly comprising:
a light emitting module comprising:
an illuminating part, and a base;
a laminated glazing comprising:
an interior glass sheet comprising a through opening,
an exterior glass sheet,
and at least one interlayer sheet of plastic material located between said interior and exterior glass sheets,
said laminated glazing having an external face configured to be oriented towards an exterior space of the vehicle, an edge and an inner face configured to be oriented towards an interior space of the vehicle;
a support plate provided on a face of said interior glass sheet opposite the at least one interlayer sheet of plastic material, said support plate comprising a plurality of lugs extending from said support plate in a direction away from the interior glass sheet; and
a spring element coupled to the lugs,
wherein the illuminating part of the light diode module is received in the through opening of the interior glass sheet, the lugs of the support plate engaging the spring element, with the spring element pressing the light emitting module against the laminated glazing.
2. The assembly according to claim 1 , wherein said plurality of lugs include four lugs around a periphery of said through opening.
3. The assembly according to claim 1 , wherein each of said plurality of lugs includes a boss, and are arranged in pairs oriented facing each other.
4. The assembly according to claim 1 , wherein each of said plurality of lugs includes a boss, and are arranged in pairs oriented opposite each other.
5. The assembly according to claim 1 , wherein said base is pressed against an inner face of said interior glass sheet by the spring element pressing under said lugs, in a direction substantially towards the inner glass sheet.
6. The assembly according to claim 1 , wherein said light-emitting diode module further comprises a first pair of inclined faces and a second pair of inclined faces, each of said plurality of lugs including a boss resting under each inclined face in direction substantially towards the inner glass sheet.
7. The assembly according to claim 1 , said plurality of lugs comprising first and second pairs of lugs; and said spring element comprises a central zone resting on said base of said light emitting module, a first pair of branches being secured under a respective one of said first pair of lugs, and a second pair of branches being secured under a respective one of said second pair of lugs.
8. A mounting plate comprising the assembly according to claim 1 .
9. A motor vehicle comprising the assembly according to claim 1 .
10. The assembly according to claim 1 , wherein said illuminating part is applied against the entire bottom of said through opening.
11. The assembly according to claim 1 , wherein said support plate has a hole extending around said through opening.
12. The assembly according to claim 11 , wherein said hole has a general rectangular shape.
13. The assembly according to claim 1 , wherein said support plate comprises side guide walls.
14. The assembly according to claim 13 , wherein said support plate comprises a plurality of side guide walls, at least one side guide wall having at least one lateral support.
15. A method of assembling an assembly according to claim 1 , said method comprising:
applying an adhesive material to at least one of said support plate and said inner face of the interior glass sheet;
depositing said support plate on said inner face;
assembling said light emitting module to said support plate by means of the spring element such that at least one of said base is positioned against an inner face of said interior glass sheet and said illuminating part is positioned against a bottom of said through opening by simultaneously pressing said spring element on said light emitting module and under said lugs.
16. The method according to claim 15 , further comprising marking said inner face of said interior glass sheet before applying the adhesive material.
17. The assembly according to claim 1 , further comprising means for blocking light leaking through the interior glass sheet.
18. The assembly according to claim 17 , wherein said means for blocking light is at least one diffusion-barrier plate provided adjacent to said support plate and against said inner face of the interior glass sheet.
19. The assembly according to claim 18 , wherein said diffusion-barrier plate is integral with said support plate.
