Embodiment Construction

[0055] figure 1 The embodiment shown in corresponds to the invention in its simplest form. Around a laminated glazing formed by a first glass sheet 1 and a second glass sheet 2 bonded to each other by means of a laminated spacer, a light emitting diode module (LED module) 8 is arranged with LEDs, LED The emitting surface 31 faces the edge 13 of the first sheet. The first main surface 11 of the first glass sheet 1 and the second main surface 22 of the second glass sheet 2 are in contact with the interior and exterior of the vehicle, respectively. The laminated glazing is bonded to the body 14 of the vehicle using a glue bead 10 . The glue edge 10 is in direct contact with the first main surface 21 of the second sheet in the free area 9 for receiving the glue edge. The area 9 and the glue edge 10 are thus positioned in a peripheral position relative to the LED module 8 . The latter are therefore in the "dry zone", separated from the external environment ("wet zone") by the g...

Abstract

The present invention relates to an illuminated glazing for a vehicle, including: a first transparent glass sheet (1) having a first main surface (11), a second main surface (12) and an edge surface; a second transparent glass sheet (2) having a first main surface (21), a second main surface (22) and an edge surface; a laminate insert (3) in adhesive contact with the second main surface (12) of the first sheet (1) and with the first main surface (21) of the second sheet (2); one or more light-emitting diode modules (LED modules) (4) which each comprise a plurality of light-emitting diodes (LED) (4) and associated electronic components attached to a holder, the modules being positioned such that the emitting surface (31) of the LEDs is opposite the edge surface (13) of the first glass sheet; and a light-extracting element, which is preferably located on one of the main surfaces of the first glass sheet.

Description

technical field [0001] The present invention relates to a luminous glazing for a vehicle, in particular a luminous glazing forming part of the roof of a motor vehicle. Background technique [0002] It is known practice to incorporate light-emitting diode modules (LED modules) at the edge of a single sheet or luminous glazing unit, so that the light emitted by the LED enters via the edge of the glass sheet and is thereby guided until diffused Diffusion elements extract light from the waveguide and diffuse it towards the interior or exterior of the vehicle (see for example International Applications WO 2010 / 049638, WO 2010 / 049639, WO 2011 / 092419 and WO 2011 / 092420, and Jul. 2011 French application n° 1157011 filed on the 29th and not yet published at the time of filing this application. [0003] The light output of such glazing units illuminated via the rim generally does not exceed 10% due to light loss due to light absorption by the glass acting as a waveguide and / or by mat...
