Definitions
- the invention relates to a lighting system, in particular for a motor vehicle lighting member, with integrated LEDs, in particular LEDs integrated into an optical module.
- Some lighting systems include a printed circuit board equipped with light-emitting diodes, commonly called LED (light emitting diode), electrically connected to the printed circuit.
- a printed circuit board often designated by the acronym PCB (Printed Circuit Board)
- PCB Printed Circuit Board
- This plate is flat and consists of an assembly of one or more thin layers of copper separated by an insulating material. Such a plate can be rigid or flexible.
- a printed circuit board or plate equipped with LEDs is generally arranged perpendicular to the desired illumination direction for good light rendering, the majority of the light beam being emitted by the diodes in one direction. perpendicular to the printed circuit board.
- a printed circuit board or plate equipped with LEDs is generally arranged perpendicular to the desired illumination direction for good light rendering, the majority of the light beam being emitted by the diodes in one direction. perpendicular to the printed circuit board.
- such positioning perpendicular to the lighting direction imposes a large size on the projector and design constraints.
- lighting systems involving a light optical module associated with LEDs to provide a light guide function.
- the LEDs are then arranged at a small distance from the optical module so that the optical module receives the light emitted by the LEDs.
- the optical module is often integrated with another element of the lighting system, for example a mask or a deflector. Such masks often extend perpendicular to the direction of illumination of the LEDs, at a distance from them.
- Such lighting systems thus consist of many elements to be arranged with respect to each other which can make their assembly complex.
- such lighting systems may have a large volume which may limit their arrangement and shape, which is undesirable, particularly in the automotive field.
- each LED is differentiated and visible. For aesthetic reasons, it may be wise to improve the stylistic aspect of the lighting system while maintaining its lighting functions.
- an object of the invention relates to a lighting system, in particular for a motor vehicle headlamp, comprising a printed circuit board equipped with light-emitting diodes able to produce light, and a shaped optical module for propagating and transmitting said light, said optical module having a receiving surface for receiving said produced light and an emission surface for retransmitting said produced light, characterized in that said optical module has a housing for receiving said printed circuit board equipped with light emitting diodes and in that said housing has an inner wall forming said receiving surface.
- the lighting system obtained is particularly simple and compact.
- the optical module may have an aesthetic appearance of the "trompe-oeil" type, because it may seem somehow suspended inside the lighting system, without visible support or holding elements. It is thus possible to realize a lighting system with a luminous element (assembly formed of the printed circuit board and the light-emitting diodes) which can be deported without being integrated with another element of the lighting system such as a mask or a reflector, in particular for lighting systems forming optical blocks of a motor vehicle.
- the positioning of the circuit board inside the volume of the optical module allows the latter to capture most of the light radiation emitted by the light-emitting diodes, in particular from 95 to 100% of the light radiation emitted.
- all the light radiation emitted by the LEDs can be picked up when the circuit board closes the housing of the optical module.
- the present invention thus makes it possible to reduce the losses of light.
- the light rendition can be improved depending on the distance between the LEDs of the receiving surface or the arrangement of the receiving surface.
- this reception surface may be at a distance of the order of 0.5 to 5 cm from the LEDs.
- the receiving surface and the LEDs may be arranged to allow illumination of the receiving surface at an angle of between 120 ° and 250 °, preferably at an angle of between 150 ° and 200 °. °, or even between 170 ° and 190 °, in particular taking the value of 180 °.
- the optical module may be formed of a polymeric or glass material, preferably translucent or transparent, capable of propagating and guiding at least one light beam flowing inside its volume, in particular a light beam. emitted by electroluminescent diodes.
- the material used may be any material suitable for guiding light radiation, such as a glass or polymer material, colored or not, for example polycarbonate or poly (methylmethacrylate) (PMMA).
- PMMA poly (methylmethacrylate)
- transparency is the physical property that allows a material to let the light pass without it undergoes dispersion.
- the photons follow the laws of Snell-Descartes.
- said receiving surface and / or said emission surface may have at least one portion capable of diffusing a fraction of said light and / or a volume between a portion of the reception surface and a portion of the emission surface may be able to diffuse a fraction of said light.
- diffusion means that a material, or in this case at least a portion of inner or outer surface of the module, passes light, but the photons are dispersed and do not follow then more the laws of Snell-Descartes.
- a material is also called translucent material.
- a portion of the receiving surface and / or a portion of the transmitting surface, and / or a volume between a portion of the receiving surface and a portion of the transmitting surface, can therefore be arranged for the diffusion of a fraction of the light rays.
- the receiving surface portion and / or the transmitting surface portion and / or a volume between a portion of the receiving surface and a portion of the transmitting surface may be at least partially grained, textured or frosted, according to methods known per se, or be in translucent material, to allow dispersion or light scattering.
- a grained, textured or frosted portion may extend over a sufficient thickness to allow diffusion of the light rays, or over the entire thickness of the optical module.
- Part of the optical module can thus be made of a translucent material in order, for example, to hide the printed circuit board and the LEDs, another part being made of transparent material.
- Such an optical module can be made in a single piece or in several pieces assembled.
- the receiving surface portion and / or the transmitting surface portion and / or the volume between a portion of the reception surface and a portion of the emission surface, capable of diffusing a fraction of said light can be located so that the printed circuit board is not visible from at least one outer area of the optical module, for example a side area.
- the inner wall of the housing of the optical module may comprise at least two side walls and at least one bottom wall, in particular a single bottom wall when the printed circuit board closes the housing.
- said at least two side walls can form the receiving surface portion capable of diffusing a fraction of said light.
- said receiving surface may have at least one other portion able to converge another fraction of said light. This can make it possible to concentrate a fraction of the light in a particular direction of the optical module, for example towards an area that is to be made brighter than the rest of the optical module.
- this receiving surface portion able to converge another fraction of the light can be arranged to converge this fraction of the light towards a particular area of the emission surface.
- the at least one other receiving surface portion has at least one optical collimation device for the light.
- the optical device for collimation, deflection or convergence of light rays can involve a plurality of conventional Fresnel lens optical elements, diopters, prisms or facets.
- Such an optical device is intended to converge the incident light rays to the emission surface of the optical module, in particular to a particular area of the transmission surface of the optical module.
- the optical collimation device may be advantageously fixed on at least one surface area of the other portion of the inner wall, or may be etched on said surface area, by methods known per se.
- the inner wall of the housing of the optical module may comprise at least two side walls and at least one bottom wall, in particular a single bottom wall when the printed circuit board closes the housing.
- said bottom wall may form the other receiving surface portion able to converge a fraction of said light.
- the housing may have an inner wall portion adapted to diffuse a fraction of the light rays and another inner wall portion adapted to converge another fraction of said light.
- Such an arrangement offers the aesthetic advantage of masking the LED light source (s). We can thus hide the light source from the eyes of a human being.
- the optical module thus ensuring the lighting function by diffusion and transmission of the light beam, can thus be fully illuminated continuously and homogeneously by all the LEDs.
- the portion of the light diffusion wall may notably allow lateral illumination of the module by masking the LEDs, the portion of the inner ray convergence wall being able to contribute to the function module lighting. In this case, the visual aspect of such a module is improved in stylistic terms.
- said inner wall of the housing may comprise at least two side walls and at least one bottom wall, in particular a single bottom wall, and the emission surface of said optical module may have a substantially parallel outer surface.
- said bottom wall and at least two outer lateral surfaces substantially parallel to said at least two side walls respectively.
- the emission surface can thus form an outer wall of the optical module, in particular almost the entire outer wall of the optical module.
- the outer surface substantially parallel to the bottom wall can thus be, for example, an outer surface called "front" as opposed to the position of the housing which can lead to the rear of the optical module.
- the outer lateral surfaces may form a portion of emission surface capable of diffusing light. For this purpose, this portion may be at least partially grained, textured or frosted.
- the housing may be a groove or groove opening on a rear face opposite to the outer front surface, for example parallel or substantially parallel thereto, for example over the entire periphery of the module.

- the optical module may have a crown shape or the like which may be cylindrical, conical or frustoconical, or even elliptical.
- the invention is however not limited to a particular form of the optical module, which is capable of taking any form appropriate to the lighting system in question.
