    OBJECT OF THE INVENTION

    The subject of the present patent application is a lighting device for a vehicle according to claim 1, which incorporates notable innovations and advantages, and its associated fixing procedure according to claim 13, which also incorporates 10 notable innovations and advantages.


    BACKGROUND OF THE INVENTION
     fifteen
    At present there is a need in the automotive sector to improve the fixation and positioning of LED diodes with respect to their corresponding light guide, and to face problems such as non-robust clipping, that LED diodes, whether normal or RGB, they are not exactly positioned in front of the light guide, and there are losses due to an air gap between the emitting module and the light guide. It is also desirable that 20 LED diodes can be replaced, in case of failure thereof before the expected useful life period.

    Specifically, it is known from the state of the art, as reflected in EP2775197, a device with a light guide that extends into a housing 25 for the diffusion and distribution of a light beam of an LED. The light guide includes a distal end, and is provided with a mounting plate to be assembled on a printed circuit board. The mounting plate is sandwiched between a mask and the printed circuit board, to ensure that the light guide is in position, facing an axis of the light guide. A method for mounting the lighting and / or signaling device 30 is also included.

    This document discloses a positioning between the PCB (or printed circuit board) and the light guide. The positioning of the PCB with respect to the housing is also observed by means of a plurality of projections of the housing inserted into holes 35 of the PCB. The light guide is positioned with respect to the PCB and the housing by means of the plurality of projections of the housing, through holes in the mounting plate of the light guide. The connection between the housing, light guide and PCB components is carried out by means of the projections of the housing. There is also the mask component that presses and packages the whole set. Although there are no screws, the assembly is complex, in addition to needing an additional piece, not offering the advantages of the present invention, explained below.

    More specifically, a series of disadvantages of EP2775197 are detailed:
    - in said document EP2775197 the PCB is not conveniently interchangeable. It is required to remove the mask and the light guide, prior to being able to remove the PCB. The manipulation of a light guide by an operator in a workshop is not allowed on many occasions in order not to damage the light guide.
    - The invention disclosed in EP2775197 aims to control the air gap between the light emitter and the distal end of the light guide. On the contrary, it presents 15 deficiencies in the centering of said light emitter with respect to the light guide: the positioning is carried out by two projections in relation to two holes, being in addition to the pin hole type, not allowing a precise adjustment due to the great tolerances of this type of union.
     twenty
    It is also known from the state of the art, as reflected in document US20140029292, a linear lighting device that includes an elongated light guide, a light source disposed at one end in a longitudinal direction of the light guide, and a housing with a light guide housing and light source. The light guide has a plurality of grooves arranged in its longitudinal direction, and has a stepped cutout 25 at the other end, and a portion that protrudes on an inner surface of the box facing an opening.

    In said document, a fastening between the light guide and the housing is observed, which comprises openings to accommodate projections of the light guide, which allow its positioning. A fixation is also observed between the PCB module and the housing. In the figure you can see a housing cover, which is an additional piece necessary for the assembly of the assembly, inside which the PCB is housed. This document does not allow to solve the problem of positioning between light guide and PCB, since PCB is not positioned. 35

    Thus, it is seen that there is still a need for a lighting device for a vehicle and associated fixing procedure, such that it presents a simpler assembly and, in turn, is removable.

    DESCRIPTION OF THE INVENTION

    At present, the lighting devices for a vehicle based on LED diodes and light guides, may present problems of positioning and orientation between the light emitter, or LED diode, and the light transmitting means, or light guide. There are also 10 difficulties when replacing these components throughout the life of the device.

    The present invention consists of a lighting device for a vehicle, and associated fixing procedure, which allows positioning without the possibility of error, increasing efficiency by minimizing air spaces between the LED and the light guide, and enabling LED module replacement in case of defect. In addition and advantageously, in the same simple assembly movements of the light guide and the light emitter, the position of the light emitter with respect to the light guide is controlled. The centering between both components is of special relevance in RGB diodes, where a precise little centering prevents homogeneous colors from being generated throughout the entire light guide.

    The following components come into play in the present invention: light guide, housing, and light emitting module, which encompasses the LED, the printed circuit board or PCB, connectors, and various attached electronics. 25

    The present idea seeks to position the light guide with respect to the module comprising the PCB, LED diode and other electronics, through its precise positioning in the housing, which includes fixings for both components. It is intended that the assembly movements are easy and do not give possibility of error. 30

    Currently, in the lighting devices for a vehicle that require an LED light module, a guide and a support, the guide and support module are normally independent. The idea of the present invention pursues that the module is integrated in the device, simplifying the final package, and reducing light leakage. In the case of 35 RGB systems, or color diodes, it provides the advantage of a better alignment of the LED connection with respect to the light guide, improving the mix of colors and the illumination appreciated, as previously mentioned.

    Thus, and more specifically, the invention consists of a lighting device for a vehicle, where the lighting device comprises a housing, at least one light emitting module, and at least one light guide, where the at least one guide of light transmits a light emitted by the at least one light emitting module, where the housing comprises at least a first housing, and at least a second housing, where the lighting device comprises at least a first guiding means, where the at at least a first guiding means positions the at least one light guide in the at least one first housing, and at least a second guiding means, where the at least a second guiding means positions the at least one light emitting module in the at least a second accommodation. Thus, and by means of two independent and complementary guiding means, one for the light guide and the other for the light emitting module, 15 better performance is achieved in terms of simplicity of assembly, and in terms of the accuracy of the relative distance and orientation to each other.

    It is noted that the invention comprises as essential features the presence of the housing, which in turn comprises first positioning or guidance means 20 for the light guide, and second positioning or guidance means for the emitting module. It is therefore noted that the at least one first guiding means is independent of the at least one second guiding means, important in order to reduce tolerances and perform precise centering. It is therefore a device that integrates and encompasses both components. Thus, it is possible to correctly position the light guide against an LED, since the light guide comprises at least one projection that can be coupled to at least one first guiding means, restricting two degrees of freedom, and the light emitting module comprises at least a projection attachable at least one guiding means, restricting at least two degrees of freedom.
     30
    It is therefore noted that, taking advantage of the mounting system described for the lighting device of the present invention, it is achieved, if required, to assemble a plurality of light guides positioned on a single light emitting module. Alternatively, two light emitting modules can be positioned with respect to the same light guide, one at each end of the light guide, by the teachings disclosed by the present invention.

    Thus, by means of the lighting device, the assembly by the operators in the assembly plant is facilitated, and the chances of the operators 5 being wrong in said assembly are minimized, while allowing the exchange of components in failure case.

    Advantageously, the at least one light emitting module comprises at least one light emitter and wherein the at least one light guide comprises at least one end, such that the at least one first guiding means and the at least one second Guiding means position the at least one light emitter facing at least one end. In this way it is possible to improve the centering between the light emitter, or LED diode, and the light guide, in the YZ plane, that is, in the plane perpendicular to the direction of the light guide, a factor that is especially advantageous for RGB LEDs, in which a perfect centering is needed to generate homogeneous colors throughout the entire light guide. By centering or centering is understood the alignment on the same axis, of the axial axis of the light guide, and the central point of the light emitter, as well as the orientation of the outgoing light by said central point of said light emitter.
     twenty
    Another beneficial effect is the reduction of light leaks between the LED emitter and the light guide, in the direction of the light guide itself, or X axis, according to a three-dimensional system of XYZ coordinate axes.

    According to another aspect of the invention, the at least one first guiding means comprises at least one third housing arranged in the housing, at least one first projection arranged in the at least one light guide, where the at least one first projection is capable of being guided in the at least one third housing, so that the at least one light guide is guided in the at least one first housing substantially in a first direction. In this way, the movement of the light guide in its assembly is a linear movement, and therefore easy to carry out by the assembly operator. Said movement is complemented, in a preferred embodiment, with the insertion of the first projection into the third housing, thereby achieving an adjustment of the position of the light guide according to an X-axis direction, that is, substantially the axis direction. from the light guide itself.
     35
    More particularly, the at least one third housing comprises a narrowing in the first direction, so that the guiding or insertion of the first projection in the third housing is performed in a manner oriented towards its final insertion position, starting from a greater width, which increases and facilitates its initial positioning at the initial moment of said insertion, facilitating the operation. 5

    In a preferred embodiment of the invention, the at least one third housing comprises a first zone and a second zone, where the first zone comprises dimensions substantially larger than the dimensions of the at least one first projection, and the second zone comprises dimensions substantially equal to the dimensions of the first outgoing 10. In this way the first projection is finally fitted to the bottom of the second zone of the third housing, so that the movement of the light guide is restricted both in the third, longitudinal direction of the light guide, and in the second direction, transverse to the light guide and also to the direction of insertion in the housing.
     fifteen
    Advantageously, the narrowing is progressive in the first direction, so that it facilitates, as mentioned, the insertion and assembly operation, allowing the light guide to be positioned more precisely, in the direction of the X axis, that is to say in the direction of its own axis. It can be said that the shape of the narrowing of the third housing is funnel-type, that is, progressively narrowing to the final position 20.

    According to another aspect of the invention, the first address is substantially perpendicular to a third address, where the third address is the emission address of the at least one light emitter. In this way the assembly operation does not imply a fitting, but only the realization of a linear assembly movement, which implies having better assembly tolerances. Preventing the movement of the light guide with respect to the light emitter in the third direction as a mounting action is beneficial in order to obtain a correct centering, thus minimizing mismatches and assembly errors. It is specified that the third direction is the direction essentially perpendicular to the plane where the light emitter 30 is located.

    According to yet another aspect of the invention, the at least one light emitting module comprises a frame, where the frame at least partially covers the at least one light emitter, at least one printed circuit board and at least one connection means. Said frame 35 can also cover and house other electronic components, the heat diffuser, etc ..., simultaneously offering easier handling with greater ease of assembly. A single element is then manipulated, which will be positioned with respect to the housing, thus conveniently assembling and connecting the light emitter.
     5
    In a preferred embodiment of the invention, the at least one second guiding means comprises at least one slot disposed in the housing, and at least one second projection disposed in the frame, where the at least one second projection is capable of being guided in the at least one slot, so that the at least one light emitting module is positioned in the at least one second housing substantially in a second direction. In this way, a positioning system is available between the light emitting module and the housing, specifically a guide means, rail type, through which a groove of the housing conducts the assembly of the light emitting module towards its unique positioning in the housing. Thus, with a linear sliding movement along the second direction, the light emitting module 15 is introduced into the housing in the unequivocal position, without the possibility of error.

    It should be mentioned that the at least one second direction is substantially perpendicular to the third direction. The second direction being that of the insertion of the light emitting module, and the third direction, the axial one of the light guide, it is observed that they are complementary directions when it comes to achieving a suitable assembly.

    According to yet another aspect of the invention, the frame comprises a first opening, where the first opening extends in the second direction, so that the at least one end of the at least one light guide is partially covered by the frame 25 of the at least one light emitting module, the at least one light guide being positioned in the at least one first housing and the at least one light emitting module being positioned in the at least a second housing. This closes the possibility of an accidental release of the light guide with respect to the housing and the light emitting module. 30

    Thus, the end of the light guide is partially covered by the frame of the light emitting module, thus allowing the sequential assembly of both components, further achieving that the frame protects said area from the end of the light guide. Additionally, the end of the light guide is facing at least one light emitter, and allowing a minimum air gap between the end of the light guide and the light emitter, in its mounting position.

    On the other hand, point out that, in a first embodiment, the first address and the second address may be the same. According to a preferred embodiment, the first address and the second address may be perpendicular. Both the first and second addresses can be any that are perpendicular to the third address. In this way the air gap between the light emitter and the end of the light guide is always controlled. In order to improve the centering and positioning between both components, it is preferable that the first direction and the second direction are either equal or 10 perpendicular, thus being easier to control the position and tolerances between the end of the guide light and the light emitting module.

    According to yet another aspect of the invention, the housing comprises a second opening, where the second opening extends in the second direction, so that a wiring 15 is capable of being displaced by the second opening in the guiding movement of the at least one light emitting module in the at least a second housing, where the wiring is connected to at least one connection means of the at least one light emitting module. In this way the lighting device has adequate access for the power supply wiring. This feature allows an electrical connection to be carried out with the light-emitting module 20 outside the housing, its handling and connection being easier. Subsequently, with a linear movement of the light emitting module frame, said light emitting module will be positioned and fixed with respect to the housing, maintaining the previously made electrical connection. In this way, the lighting device, which could cause displacements and errors in the positioning of the components, is not subsequently manipulated.

    Additionally, the fixing of the light emitting module in the housing is carried out by means of a simple clipping system, which results from the same injection molds of both the housing and the frame of the light emitting module. 30

    The object of the present invention is also a fixing method for the lighting device for a vehicle, comprising the steps of: i) positioning the at least one light guide in front of at least one first housing housing, ii) sliding the at least one light guide by means of the at least one first guiding means, where the sliding 35 of the at least one light guide is according to the first direction, iii) positioning the at least one light emitting module in front of the second housing housing, and iv) sliding the at least one light emitting module by means of the at least a second guiding means, where the sliding of the at least one light emitting module is according to the second direction. Thus, and being the first direction and second direction complementary, the lighting device is perfectly assembled, and its components fixed together, preventing accidental disassembly. In addition, by means of two essentially linear movements of the light emitting module and the light guide with respect to the housing, an exact positioning between both is performed.
     10
    Additionally, the step of sliding the at least one light emitting module comprises inserting the at least one end of the at least one light guide into the first opening. Thus said end of the light guide is housed in its exact position in said first opening, and positioned in front of the light emitter, minimizing light losses.
     fifteen
    On the other hand, the step of positioning the at least one light guide in front of at least one first housing comprises positioning the at least one first projection in front of at least one third housing, so that the light guide is positioned on the axis X, and its end at the appropriate distance from the light emitter.
     twenty
    In addition, the step of positioning the at least one light emitting module in front of the second housing comprises positioning the at least one second projection in front of the at least one slot, so that the light emitting module is correctly housed and positioned in the housing. .
     25
    According to another aspect of the invention, the fixing method for the lighting device comprises an additional step of connecting the wiring to at least one means of connecting the at least one light emitting module, where the step of connecting the wiring is prior to the step of sliding the at least one light emitting module. Thus, when connecting outside the use position, the operation is more convenient for the assembly operator. The opening allows the wiring to also be moved to its use position in the same guiding movement of the at least one light emitting module.

    The attached drawings show, by way of non-limiting example, a lighting device for a vehicle and associated fixing procedure, constituted according to the invention. Other features and advantages of said lighting device for a vehicle and associated fixing procedure, object of the present invention, will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT


    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Thus, as seen in Figures 1, 3 and 4, the present invention consists of a lighting device 1 for a vehicle, where the lighting device 1 30 comprises a housing 2, at least one light emitting module 3, and at least one light guide 4, where the at least one light guide 4 transmits a light emitted by the at least one light emitting module 3, where the housing 2 comprises at least a first housing 21, and at least a second housing 22, where the lighting device 1 comprises at least one first guiding means 6, where the at least one first guiding means 6 35 positions the at least one light guide 4 in the at least one first housing 21, and at at least one second guiding means 7, where the at least one second guiding means 7 positions the at least one light emitting module 3 in the at least one second housing 22.

    Mention that the present invention contemplates the alternatives of having more than one light guide 5 positioned on a single light emitting module 3, and a single light guide 4 with two light emitting modules 3 at each end 41.

    Note that the fixing of the light guide 4 is carried out with small clamps or other clip-like systems arranged along the light guide 4. 10

    More particularly, as seen in Figures 1 and 3, the at least one light emitting module 3 comprises at least one light emitting 32 and wherein the at least one light guide 4 comprises at least one end 41, of such that the at least one first guiding means 6 and the at least one second guiding means 7 position the at least one light emitter 32 15 facing at least one end 41.

    According to another aspect of the invention, as seen in Figures 1 and 2, the at least one first guiding means 6 comprises at least one third housing 61 disposed in the housing 2, at least one first projection 62 disposed in the at least one light guide 4, where 20 the at least one first projection 62 is capable of being guided in the at least one third housing 61, so that the at least one light guide 4 is guided in the at least one first housing 21 substantially in a first direction 51.

    Note that the components of the invention, which are the housing 2, the light guide 4 and the light emitting module 3 (which includes electronic, LED, PCB, diffuser, connector ...) are obtained from its own injection mold, not requiring additional components in order to perform its positioning and fixation.

    As can be seen in detail in Figure 1, the light guide 4, which comprises an essentially elongated geometry is positioned in the housing 2 by the first guiding means 6. Specifically, the first guiding means 6 is constituted by a first projection 62, in the form of a rectangular prism, which is extracted from the same injection mold of the light guide 4. This first projection 62 is introduced and slid along a third housing 61, which is generated in the same injection mold of the housing 2. This third housing 61, in order to improve and facilitate the assembly of the light guide 4, comprises a funnel shape along the first mounting direction 51. Thus, the third housing 61 narrows to comprise dimensions substantially equal to those of the first projection 62, so that the first projection 62 is partially retained in the third housing 61. Thus, and only with an essentially linear movement 5 in The first direction 51 restricts the position of the light guide 4 in the third direction 53, of particular importance since it allows controlling the air gap between the end 41 of the light guide 4 and the light emitter 32.

    More specifically, as seen in Figures 1 and 2, the at least one third housing 61 comprises a narrowing in the first direction 51.

    According to a preferred embodiment of the invention, as seen in Figures 1, 2 and 4, the at least one third housing 61 comprises a first zone 611 and a second zone 612, where the first zone 611 comprises dimensions substantially greater than the 15 dimensions of the at least one first projection 62, and the second zone 612 comprises dimensions substantially equal to the dimensions of the first projection 62. In this way positioning between light guide 4 and housing 2 is achieved.

    In more detail, as seen in Figures 1 and 2, the narrowing is progressive in the first direction 51, assimilating into a conical type. It is located on the side of the first U-shaped housing 21, and extends in the first direction 51.

    According to another aspect of the invention, as seen in Figures 1, 3 and 4, the first address 51 is substantially perpendicular to a third address 53, where the third address 53 is the emission address of the at least one emitter of light 32. As mentioned, this point is especially advantageous for controlling the distance of air between the end 41 of the light guide 4 and the light emitter 32.

    According to yet another aspect of the invention, as seen in Figures 1, 2, 3, 4 and 5, the at least one light emitting module 3 comprises a frame 37, where the frame 37 covers at least partially the less a light emitter 32, at least one printed circuit board 35 and at least one connection means 34. Additionally, the frame 37 can encompass different essential components, such as a heat diffuser, other electronic components relevant to the operation of the emitter of light 32 ... these being unseen 35 in the exposed figures. The use of a light-emitting module 3 comprising a frame 37 is advantageous, since the manipulation in the assembly operations by an operator is simplified.

    On the other hand, as seen in Figure 3, the at least one second guiding means 7 5 comprises at least one groove 71 disposed in the housing 2, and at least one second projection 72 disposed in the frame 37, where the at least a second projection 72 is capable of being guided in the at least one groove 71, so that the at least one light emitting module 3 is positioned in the at least one second housing 22 substantially in a second direction 52. The second protrusion 72 is a rail or guide 10 extending in the second direction 52. This second protrusion 72 fits into the groove 71, which also extends in the second direction 52. They make the assembly a linear movement in the second direction. 52. This second projection 72 is obtained in the same injection mold of the frame 37. In addition, the groove 71 is also obtained from the same injection mold of the housing 2, so it is observed that in no case is complexity increased. or et Manufacturing components of the components of the present invention, while minimizing the number of necessary components.

    As can be seen in figure 3, the frame 37, which encompasses the light emitting module 3, is mounted in the housing 2 with a linear movement along the second direction 20 52. In this way it will also be limited an air gap between the light emitting module 3 and the end 41 of the light guide 4.

    According to a preferred embodiment of the invention, as seen in Figures 1, 3 and 4, the at least one second direction 52 is substantially perpendicular to the third direction 53.

    In the preferred embodiment set forth in the figures, it is observed how the first direction 51 and the second direction 52 are perpendicular to the third direction 53. As mentioned, it is especially beneficial in order to control the air gap 30 between the light emitter 3 and the end 41 of the light guide 4. Additionally, the first direction 51 is perpendicular to the second direction 52, thus improving the centering between the light emitter 3 and the end 41 of the light guide 4 .

    According to another aspect of the invention, as seen in Figures 1 and 5, the frame 37 comprises a first opening 31, where the first opening 31 extends in the second direction 52, so that the at least one end 41 of the at least one light guide 4 is partially covered by the frame 37 of the at least one light emitting module 3, the at least one light guide 4 being positioned in the at least one first housing 21 and the at least one being light emitting module 3 positioned in the at least one second housing 22. This opening is necessary to allow sequential mounting of the light guide 4 and the subsequent assembly of the light emitting module 3.

    According to yet another aspect of the invention, as seen in Figure 3, the housing 2 10 comprises a second opening 24, where the second opening 24 extends in the second direction 52, so that a wiring 8 is capable of being displaced by the second opening 24 in the guiding movement of the at least one light emitting module 3 in the at least one second housing 22, where the wiring 8 is connected to at least one connection means 34 of the at least one emitting module of light 3. 15

    It should be mentioned that, as shown in the section of Figure 4, the light emitting module 3 comprises fixing means 33 of the frame 37 to the housing 2, so that it is retained in the use position. The fixing means 33 are preferably clips, which are obtained from the same injection mold as the corresponding component 20, both the projection of the frame 37 and the projection or fixing means 33 of the housing 2 that fit between them for retention. of the light emitting module 3, and its retention essentially in the second direction 52. To facilitate the removal of the light emitting module 3 from the housing 2, the fixing means 33 comprise a tab. Said tongue is capable of being compressed in order to separate the clip-like mechanism that retains the projection of the frame 37 with the projection of the housing 2.

    On the other hand, fixing means (not seen in the figures) allow to retain the light guide 4 in the use position. By way of example, they are U-shaped clamps that retain said light guide 4, which usually has a circular shape. These 30 clamps are arranged along first housing 21 of the housing 2.

    It is also an object of the present invention, as can be seen in Figures 1 and 3, the fixing procedure for the lighting device 1 for a vehicle comprising the steps of i) positioning the at least one light guide 4 in front of the at least one first housing 21 of the housing 2, ii) sliding the at least one light guide 4 by means of the at least one first guiding means 6, where the sliding of the at least one light guide 4 is according to the first direction 51, iii) position the at least one light emitting module 3 in front of the second housing 22 of the housing 2, and iv) slide the at least one light emitting module 3 by means of the at least a second guiding means 7 , where the sliding of the at least one light emitting module 3 is according to the second direction 52.

    Additionally, as seen in Figures 1 and 3, the step of sliding the at least one light emitting module 3 comprises inserting the at least one end 41 of the at least one light guide 4 into the first opening 31. 10

    On the other hand, as can be seen in Figures 1, 3 and 4, the fixing method for the lighting device 1 of the invention comprises an additional step of connecting the wiring 8 to at least one connection means 34 of the at least a light emitting module 3, where the stage of connecting the wiring 8 is prior to the step of sliding the at least one light emitting module 3.

    It should be mentioned that, to reach the position of use, the fixing method comprises inserting the at least one first projection 62 of the at least one light guide 4 in the first zone 611 of the third housing 61, so that the at least one light guide 4 20 is located in its use position, the clips of the fixing means 33 of the at least one light emitting module 3 fit with those of the housing 2.

    Therefore, the assembly of the device and lighting 1 consists, schematically, of the following steps:
    - assemble the components that make up the light emitting module 3 in the frame 37, such as the light emitting 32, the PCB…
