Problems solved by technology

If this heat is not removed efficiently, it can lead to an undesirable increase in the temperature of the LED module, which in virtually all cases ultimately shortens the life of the module's LEDs and other electrical components

Embodiment Construction

[0047] More specifically, figure 1 Shows the edge of a laminated glazing unit with a first glass sheet 1, a second glass sheet 2 and a laminated interlayer 5 with a second front side 12 of the first glass sheet 1 It is in adhesive contact with the first front side 21 of the second glass pane 2 . The first front face 11 of the first sheet 1 contacts the interior of the vehicle, and the second front face 22 of the second glass sheet 2 faces the exterior of the vehicle.

[0048] The second glass sheet is larger than the first glass sheet and serves to support the encapsulation element 4 and part of the heat sink 6 . The LED module 8 with top-emitting LEDs 3 is positioned such that the light-emitting face 31 of the LEDs 3 faces the edge 13 of the first glass sheet 1 . The edge 23 of the second glass sheet is covered by the encapsulation device 4 .

[0049] The light injected by the LED at the edge 13 of the first sheet is guided by the first sheet to the light extraction elemen...

Abstract

The present invention relates to a light-up window for a vehicle, comprising a first sheet of transparent glass (1) with a first main surface (11), a second main surface (12), and a cut (13), one or a plurality light-emitting diode modules (LED modules) (8) each comprising a plurality of light-emitting diodes (LEDs) (3) and associated electronic components fastened onto a printed circuit board (PCB), the modules being positioned so that the emitting surface (31) of the LEDs faces the cut (13) of the first glass sheet, a means of encapsulation (4) in contact with the first main surface (11) of the first sheet, a light-extracting element (7) preferably located on one of the main surfaces of the first glass sheet, characterized in that it further comprises a heat-dissipating element (6), which is in thermally conductive contact with the LED module, in contact with the means of encapsulation (4) and in contact with the atmosphere via a thermal exchange surface (S).

Description

technical field [0001] The invention relates to an illuminated glazing unit for a vehicle, in particular an illuminated glazing unit forming part of the roof of a motor vehicle. Background technique [0002] There are known methods to incorporate light-emitting diode modules (LED modules) in the edges of single-layer or laminated glazing units, so that the light emitted by the LEDs enters through the edge of the glass sheet and is directed by the sheet to a scattering element, scattering The element is also referred to as a light extraction device. [0003] These illuminated glazing units basically function as ambient lighting or light signaling (hence the use of low power LEDs). The light output of these edge-lit glazing units is generally limited due to light loss due to light absorption by the glass used as the waveguide and / or materials adjacent thereto. [0004] Since it is often difficult or even impossible to significantly reduce the light loss due to absorption, an...
