Problems solved by technology

Said constant thickness between 6mm and 8mm is not able to comber the entire width of the opening of the above-mentioned vitreous according to conventional manufacturing techniques of polycarbonate parts of this type, usually limited by the thickness of the injection molding
In fact, if figure 2 As shown, the functional gap between the flat light guide and the glass leads to a direct visibility into the housing interior from the outside, which is not aesthetically pleasing

Embodiment approach

[0036] According to the invention, device 1 also comprises a flat light guide 40 and at least one light source adapted to project said light in said flat light guide 40 capable of diffusing said light. According to one embodiment, the device 1 comprises a plurality of light sources of the DEL (acronym for diodes é electroluminescents) type. The light diffused in the flat light guide 40 is thus conveyed towards the outside of the housing 10 by means of the above-mentioned translucent opening 21 of the glass 20 .

[0037] The flat light guide 40 is adapted to be inserted inside the housing 10 upstream of the glass 20 so as to leave an empty space between the flat light guide 40 and the glass 20 . This empty space, indicated as functional gap 50 , is required for air circulation in order to avoid any condensation inside housing 10 .

[0038] refer to Figure 4(The figure shows a cross-sectional view of the daytime running light device 1 according to the invention), the flat lig...

Abstract

The present invention relates to a light guide vehicle lighting comprising an extended end portion and / or a luminescence signal device. The device comprises: a housing (10) with an opening at the front side; at least one light source; a glass member (20) adapted to enclose the housing (10), wherein the glass member (20) comprising a translucent opening adapted to transmit light, and the opening isextended in the predetermined width of the glass member (20); a flat light guide (40) that diffuses light, the flat light guide being arranged at a predetermined distance from the glass member (20) to form an empty space, the flat light guide (40) comprising a main body facing the shell a front portion facing the body (10) and facing the glass member (20), and a coupling portion coupling the front portion to the main body, the front portion of the flat light guide (40) including an enlarged thickness section having a thickness greater than a width of the opening of the glass member (20).

Description

technical field [0001] The present invention generally relates to lighting and / or lighting signaling devices, more particularly for motor vehicles. For the sake of simplicity, such lighting and / or lighting signaling devices are denoted hereinafter as "lighting modules". [0002] The invention thus relates to a lighting module of a motor vehicle, more precisely to a lighting module comprising a luminous signaling function implemented by diffusing the light emitted by the light source via a light guide of the flat type. Background technique [0003] It is known to arrange lighting modules at the front or rear of a motor vehicle in order to illuminate the road, especially at night, on the one hand to improve the visibility of the driver of the vehicle, and / or to indicate to other road users that the the location of the vehicle. [0004] According to the prior art, the lighting module can be a luminous signaling device whose function is to indicate the position of the vehicle ...
