Definitions
- the invention relates, in general, to light signaling devices, intended more particularly for motor vehicles, comprising a light signaling function which is performed by scattering the light emitted by a light source via a light guide of the flat type or other type of light element.
- a light signaling device is arranged at the front or at the rear of a motor vehicle in order to signal the position of the vehicle to other road users.
- a light curtain is a rather thin light guide that is used to diffuse light over its largest area (not one side or one edge).
- the guide has either an opaline appearance, or optical microphones on the surface or in the material which reflect the light perpendicularly to the surface of the guide, which creates a so-called “light curtain” effect.
- a DIS signaling device comprising a BOI box, open towards the front,
- a transparent closing wall designated by the term "glass" GLA in the remainder of the description, adapted to cooperate with said BOI box, a flat ELU light guide, suitable to fit into said BOI box and a plurality of light sources (not shown), adapted to fit into the BOI box, so as to inject light into the flat ELU light guide allowing light to be diffused.
- the ELU flat light guide is adapted to fit inside the DIS housing, upstream of the GLA lens, so as to maintain an empty space between said ELU flat light guide and said GLA lens.
- Such an empty space designated JEF functional set, is necessary for the circulation of air in order to avoid any condensation inside the BOI box and particularly on the inside face of the glass, as this condensation would be visible.
- Figures 2 and 3 illustrate rear light signaling devices of the state of the art, using a screen, or a light curtain, as optical element ULS, arranged between the SOL light source and the GLA glass closing the BOL light box
- a screen or a light curtain are said to be opaline (that is to say, not completely transparent and not completely opaque) and are able to diffuse light over their entire visible surface. This type of light element is then designated by “diffusing optical elements”.
- the GLA lens and the ELU light element are several parts that must be assembled with a positioning constraint relative to each other, which represents an additional cost compared to a single part.
- the JEF offset between the outer surface of the GLA lens and the ELU luminous element can, in the case of a complex shaped lens with significant relief, generate a visual inconsistency between the two (visual deformations by refraction).
- the invention therefore aims to overcome these drawbacks by providing a light signaling device in which the glass and the light element form a single piece which, in addition to the reduction in cost, simplifies assembly and avoids visual inconsistencies. .
- the currently necessary clearance between the glass and the light element, to prevent condensation, has been eliminated.
- the present invention proposes a light signaling device for a vehicle, in particular for a motor vehicle, said device comprising:
- the device is characterized in that the luminous element is molded onto a part of the lens to form a single-piece optical element: the portion of mirror corresponding to the outer face of the one-piece optical element and the light element covering the inner face of the lens part, corresponding to the inner face of the one-piece optical element.
- the one-piece optical element defines a hollow body obtained after two-material injection molding: a first type of material constituting the ice part and a second identical or different material constituting the luminous element; said hollow body forming an outward protrusion from the rest of the glass wall closing the housing.
- the luminous element is split into two parts obtained from the same injection molding process of the same second type of material; each part of the luminous element defining the inner face of the hollow body except the bottom of the hollow body which defines an exit window for the light.
- the light exit window supports a diffraction grating on its inner face.
- the ice portion has a general "U" shape, the first and second branches of which widen from the bottom of the hollow body to the rest of the ice wall; the luminous element covering the inner face of the ice part also respectively having a general shape of "U", the first and second branches of which respectively cover the first and second branches of the ice part.
- the ends of the first and second branches of the ice portion are connected respectively to the rest of the ice wall having a substantially uniform surface, by substantially flat parts.
- the interior surfaces of the substantially flat parts of the ice wall are covered with a third type of material opaque to light obtained from the same injection molding process and defining parts of glass opaque to light. .
- At least one light source is arranged to diffuse the light in the edges of the first and second branches of the luminous element used as a light guide or to illuminate the rear face (s) of the luminous element. used as an opaline screen.
- At least one light source is arranged opposite each edge of the first and second branches of the light element to illuminate each of the first and second branches of the light element and in which at least a third light source is arranged opposite the light exit window of the part of glass.
- the second object of the invention is a motor vehicle comprising at least one light signaling device as described above.
- the invention also relates to a vehicle comprising a light signaling device according to the invention.

- front arrangement will denote an arrangement oriented towards the outside of the signaling device when it is considered mounted on the vehicle.
- Figure 4 illustrates, in a sectional view in the XY plane of the XYZ frame of reference, a detail of the assembly of a part of PGL ice and of an ELU luminous element for a GLA glass with high relief.
- the profile of the PGL ice part forms a PRO protuberance which is imposed by the style.
- GLA lens of complex shape with significant reliefs (protuberances): difference in shape between the exterior lens and the internal elements (light) and therefore altered perception of the visual signature, visual deformation of the internal elements through it. radiated surfaces of ice (refraction phenomena).
- the principle of the present invention is to integrate the ELU light element into a part of the PGL glass without any clearance between the PGL part of the glass and the ELU light element, to avoid any visible condensation.
- the ELU light element and the PGL glass part form an EOM monobloc optical assembly which appears as one and the same part.
- the ELU luminous element is overmolded on the inner surface of the PGL ice portion as illustrated in Figures 5 to 9.
- the ELU light element can be chosen from a layer of opaline material, or even a light guide, or light curtain, so that the juxtaposition of the chosen element, with the thickness of the part of the PGL ice makes it possible to obtain the desired optical effect.
- the monobloc optical element EOM is produced by injecting a bi-material resin into a mold defining the shapes of the part of ice PGL and of the luminous element ELU .
- a first type of material is used for the PGL ice portion and a second material, different or identical, is used for the ELU luminous element for example a PMMA (Polymethyl methacrylate PMMA) which can be transparent, opaque or opaline, and PC (Polycarbonate).
- PMMA Polymethyl methacrylate PMMA
- PC Polycarbonate
- the monobloc optical element EOM is produced by injecting a tri-material resin into a mold defining the shapes of the part of ice PGL, of the luminous element ELU (opaline screen for example) and EGO opaque ice elements obtained from a third type of material, for example an opaque black PMMA.
- the EOM one-piece optical assembly defines a COC hollow body whose outer and inner profile has a general "U" shape.
- the first and second branches BR1 and BR2 of the “U” are substantially flared starting from the base of the “U” (corresponding to the bottom of the hollow body COC).
- the ELU light element is overmolded inside the PGL ice portion completely conforming to the interior "U" profile of the PGL ice portion. It therefore also has a general flared "U" shape.
- the ice part PGL and the luminous element ELU therefore have first and second branches BG1, BG2 and BE1, BE2 respectively.
- the first and second branches BG1 and BG2 of the PGL ice portion extend respectively by substantially planar portions PPL extending over the rest of the wall of the GLA glass, substantially uniform, closing the BOI case.
- the first and second branches BE1 and BE2 of the ELU light element stop at the level of the plane parts PPL of the wall of ice GLA.
- a layer of light-opaque material (opaque glass GLO) is overmolded with the PGL ice portion and the ELU luminous element.
- This opaque GLO lens is arranged at the base of the COC hollow body, on either side of the ELU light element, on the inner face of the PPG flat parts of the GLA lens.
- the opaque glass areas make it possible, on the one hand, to surround the transparent area (s) dedicated to the light function by preventing light leaks, on the other hand to hide from the light. exterior view the other technical components of the signaling device.
- the base of the hollow body COC corresponds to the rest of the glass GLA defining a substantially uniform wall which closes the front face of the case (not shown).
- FIGS. 7 to 9 respectively illustrate different arrangements of one or more light sources SOL with respect to the monobloc optical assembly EOM of the signaling device DIS according to the invention. These SOL light sources are used to illuminate the ELU light element integrated into the PGL ice part.
- FIG. 7 illustrates a first "mixed” arrangement in which two light sources (a first and a second LEDs) SOL1 and SOL2 respectively illuminate the first and second branches BE1 and BE2 of the light element ELU.
- the acronym LED (or LEDs in the plural) for "Light-Emitting Diode” designates a light-emitting diode commonly used as a light source in automotive vehicle lighting and / or signaling devices.
- the first LED SOL1 is arranged opposite the edge of the first branch BE1 of the light element ELU.
- the luminous flux is directly injected into the edge of the first branch BE1.
- the ELU light element is used as a light guide.
- the second SOL2 LED is arranged opposite a REF reflector of partially parabolic shape.
- the luminous flux generated by the second SL2 LED is reflected by the REF reflector towards the rear of the ELU light element which is used as an opaline screen to diffuse light over the entire outer surface of the ELU light element.
- This arrangement is said to be “mixed” because it combines illumination from the edge with illumination from the rear of the luminous element.
- Figure 8 illustrates a second arrangement in which a single light source (an LED or a row of LEDs) SOL is arranged between the first and second branches BE1 and BE2 of the light element ELU.
- a single light source an LED or a row of LEDs
- SOL single light source
- a REF reflector or other optical element such as a light guide section (not shown) can be arranged between the LED SOL and the first and second branches BE1 and BE2 of the light element ELU to confine the luminous flux towards the ELU luminous element.
- FIG. 9 illustrates a third arrangement in which the luminous element ULS is split into first and second portions ULS1 and ULS2, obtained by the same injection process and with the same second type of material.
- the first and second parts of the ELU1 and ELU2 light element match
- first and second branches BG1 and BG2 of the part of ice PGL are respectively the first and second branches BG1 and BG2 of the part of ice PGL. They do not cover the base of the “U” of the part of PGL ice (corresponding to the bottom of the COC hollow body), thus letting appear a part of transparent PGT glass defining an exit “window” for the light.
- Two light sources (a first and a second LED) SOL1 and SOL2 are arranged respectively facing the edges of the branches BE1 and BE2 of the first and second parts of the light element ELU1 and ELU2.
- the luminous flux generated by the first and second LEDs SOL1 and SOL2 are injected directly into the edges of the first and second branches.
- a third light source (third LED) SOL3 is arranged between the first and second LEDs, SOL1 and SOL2, facing the window PGT.
- This arrangement makes it possible to obtain simultaneously or independently, a brake light function and a night signal light function.
- the luminous flux generated by the third central LED SOL3 passes directly through the PGL glass part to perform the brake light function which requires more luminous flux than a function. signage at night.
- the interior surface of the PCT window, facing the third LED SOL3, may comprise a diffraction grating RED obtained during the molding of the portion of ice, PGL defining for example a plurality of optical prisms.
- the COC hollow body of the EOM one-piece optical assembly can be likened to a PRO protuberance with significant relief from the rest of the wall of the GLA lens.
- COC hollow bodies or PRO protuberances can be arranged in parallel, for example along Y, and preferably three PRO protuberances to define a light signature specific to an automobile manufacturer.
