    [0002]
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The purpose of the present patent application is a lighting device for a vehicle according to claim 1, incorporating both notable innovations and advantages.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] At present, the vehicles include at least one reflective surface, usually in the rear area of the vehicle, which has the function of reflecting a light from an external light source. These reflective surfaces are known as catadioptric or retroreflectors. Its use is also common in large vehicles, such as trucks or others, to mark its perimeter or occupied space, especially in low lighting conditions.
    [0011]
    [0012] More in detail, a catadioptric or retroreflector is an optical element with a surface that reflects the light back to the source, regardless of the angle of incidence. That is, it reflects a light wave front in the opposite direction than the incidence. This behavior is not equivalent to that of a mirror, since the latter only reflects the rays of light in the direction of incidence when it is perpendicular to the surface, that is, when the angle of incidence is 0.
    [0013]
    [0014] The properties of the catadioptric or retroreflectors are used to increase the visibility of objects in low light conditions, so they are used as active road safety elements. They are especially useful in this field because usually the light source and the observer are located approximately in the same direction that links the source and the retroreflector. These optical elements are installed in vehicles, vests, sportswear, or on asphalt, defining the lanes.
    [0015]
    [0016] The catadioptric or retroreflector is usually formed by two pieces, a first one is a plastic or tulip comprising reflecting prisms, and a second one is the support housing of said plastic or tulip. Both pieces are usually welded together by means of ultrasound, leaving a tight joint.
    [0017]
    [0018] Between both pieces, the glass or tulip and the housing, an internal air chamber is formed. Said air chamber is necessary to generate the desired optical effect, allowing a change of medium of the light waves and producing the reflection of light. Said air chamber, due to important thermal variations produced during the manufacturing process of the module or during its useful life, can generate an overpressure that causes the deformation of the plastic or tulip. Such deformation may alter the geometry of the catadioptric, so it may not meet the initial requirements with which it has been designed.
    [0019]
    [0020] In this regard, it is known from the prior art, as described in document FR2647732, an arrangement in the signaling lights of motor vehicles, comprising a translucent glass with a catadioptric surface whose prisms are protected by a welded wall to an edge that surrounds these prisms. The wall includes a socket that opens on the opposite side of the prisms, and whose bottom is perforated with a small hole that emerges towards the prisms. Said bushing receives a plug of open-cell flexible elastic material.
    [0021]
    [0022] Thus, and in view of the above, it is seen that there is still a need for a lighting device, which comprises a retro reflector or catadioptric, that avoids eventual overpressures of the air housed by the internal chamber, which could lead to a deformation of the walls of said catadioptric.
    [0023]
    [0024] DESCRIPTION OF THE INVENTION
    [0025]
    [0026] The present invention consists of a lighting device for a vehicle. Said lighting device comprises, by way of illustration, and not limitation, the following components:
    [0027] - an external lens or tulip or plastic that has a geometry of faceted walls, that is, inclined between them in order to produce the effect of a catadioptric, also known as retroreflector;
    [0028] - a housing, preferably made of plastic, arranged in a substantially parallel position, closing the lens or tulip from behind, protecting the assembly against shocks and providing a seal between the retroreflector and the housing;
    [0029] - a space or air chamber between the lens or tulip and the housing, in order to produce a change of medium, thus generating the reflection of the light beams that affect the lens or tulip;
    [0030] - a hole, which communicates the space or air chamber with the outside, in order to compensate for any overpressures generated in the air chamber;
    [0031] - a cover that can cover the hole, in order to regulate the passage of air through the hole. Said cover is obtained from the same injection mold as the housing, so that no additional parts are added;
    [0032]
    [0033] Having an impact on the need for a space or air chamber, mention that the change of medium of the light beams is necessary in order that the faceted surfaces of the transparent outer lens produce the reflection of light coming from the headlights of a rear vehicle. If you directly over-inject the plastic from the housing just behind the lens, and without a space or air chamber in between, the concept would not work.
    [0034]
    [0035] Point out on the other hand that there is a problem of deformation of the plastic, especially of the lens or tulip. The reason is that during the process of joining by welding, ultrasonic, or vibration welding between the outer lens and the housing, internal stresses are generated. This process of friction or ultrasonic welding is carried out throughout the perimeter of both components, generating a tight enclosure. To eliminate these internal tensions, some oven cycles around 80 or 90 degrees are required. In addition, because said lighting module is incorporated in a rear bumper, said bumper is also subjected to processes where the temperature must be very high. High temperatures generate an overpressure in the space or intermediate air chamber.
    [0036]
    [0037] Also during the use of the catadioptric, in the useful life of the lighting device, when the sun falls directly on the catadioptric, especially in summer, the temperature of the interior air of the chamber is significantly increased, thereby increasing the internal pressure. At these high temperatures, the plastic material used to make the retroreflector or lens also slightly decreases its stiffness, so that the increase in internal pressure can deform said retroreflector.
    [0038] Summarizing, for the lighting device of the present invention, an air space or chamber is required for the incident rays to be reflected in the lenses, producing the physical effect that the light makes a change of medium, while requiring at the same time that the space or air chamber is a tight enclosure, that is, in which there can be no entry of water or particles.
    [0039]
    [0040] As mentioned, the lighting device faces the problem of supporting an internal overpressure exerted by the air when heated on the walls of the catadioptric, with the consequence of deformation of the outer wall (lens, tulip or catadioptric). This leads to the undesired effect that the catadioptric does not meet the optical and light requirements for which it has been designed.
    [0041]
    [0042] In order to solve this technical problem, a hole or hole is added to the inner casing, and also, leaving the same manufacturing mold, and in the same injection, a cover or clamping flange of the air outlet orifice, which exerts a pressure against the hole or exit hole. Said cover or tab allows to regulate the passage of air from the air chamber to the outside. Additionally, it also prevents dust and water from entering the chamber.
    [0043]
    [0044] More specifically, the present invention consists of a vehicle lighting device where the lighting device comprises a retroreflector, or lens or tulip, and a housing, where the retroreflector rests on the housing, and where the retroreflector and the housing define a camera of air between them, where the housing comprises at least one hole, where the hole communicates the air chamber with the exterior of the lighting device, wherein the housing comprises at least one suitable flange for regulating an air passage through the at least one hole, where the at least one flange is capable of being displaced between a first position and a second position, where the at least one flange allows the passage of air through the at least one hole with the at least one flange being in the first position, and where the at least one flange closes the air passage through the at least one hole with the at least one flange being in the s second position. In this way, by means of an easily obtainable closure element in the same injection mold where the housing is obtained, the hole can be closed, thus not allowing the entry of water and dust into the space or air chamber, to the time that the air outlet is allowed, when the air pressure in the air chamber exceeds a certain pressure level.
    [0045]
    [0046] Specify that the first position is the manufacturing position, that is, the flange is separated from the housing in the area adjacent to the hole, without contact between the flange and the area of the housing adjacent to the hole. The second position, or position of use, corresponds to the position in which the flange contacts the housing in the area adjacent to the hole. As mentioned, a retroreflector means an element or surface that reflects the light back towards the source, regardless of the angle of incidence.
    [0047]
    [0048] Advantageously, the housing and the at least one flange are obtained by means of the same injection process, both the housing and the flange being of a plastic material. Thus, in a preferred embodiment the housing and the at least one flange are the same component, that is, the housing comprises the at least one flange. Thus, in said embodiments, the entire housing and flange assembly can be manufactured in a single stage of housing injection, and without the need for additional processes.
    [0049]
    [0050] According to another aspect of the invention, the housing comprises at least one clip, where the at least one clip is suitable for retaining the at least one flange in the second position, so that the flange is held fixed in the closing position of the less a hole, blocking the entry of water and dirt into the lighting device.
    [0051]
    [0052] In a preferred embodiment of the invention, the at least one clip and the housing are obtained by means of the same injection process, the clip and housing being the same component. In this way, the entire assembly, clip and housing, can be manufactured in a single injection stage, and without the need for additional processes.
    [0053]
    [0054] It should be mentioned that the retroreflector, or lens or tulip, rests on the housing by the perimeter of the retroreflector, so that an interior air space or chamber is delimited, producing the physical effect that the light makes a change of medium.
    [0055]
    [0056] In a preferred embodiment of the invention, the at least one flange is mechanically linked to the housing by means of at least one film hinge, so that the flange it can make a rotary movement from a first position to a second position, in order to close the at least one hole.
    [0057]
    [0058] More particularly, the displacement of the at least one flange from the first position to the second position comprises a 180 ° rotation around the at least one film hinge, the at least one flange being substantially in the same plane of the housing in The first position. Thus, in the injection stage to produce the housing next to the flange, no additional slides are necessary, since the entire piece can be produced in the same plane, which facilitates demolding.
    [0059]
    [0060] In a preferred embodiment of the invention, the housing comprises two clips, where each clip retains a longitudinal end of the at least one flange, so that the flange is fixed and retained in a stable manner, minimizing possibilities of games and movements, which allow the entrance of water and / or dirt. Preferably the hole is located between the two clips.
    [0061]
    [0062] More specifically, the at least one flange comprises at least one boss, where the at least one boss comprises a geometry substantially complementary to a geometry of the at least one hole. In this way a perfect coupling between the projection and the hole is produced, allowing a better tightness before the entrance of water and / or dirt.
    [0063]
    [0064] Advantageously, the geometry of the at least one hole is a truncated cone, so that the hole of the housing has an opening that facilitates the entry and coupling with the flange, and / or with a protrusion of said flange, in order to maximize The sealing effect. It should be noted that the small radius of the truncated cone is on the side closest to the air chamber and the large radius of the truncated cone is on the side furthest from the air chamber.
    [0065]
    [0066] According to another aspect of the invention, the at least one projection is arranged in the center of the flange, so that the flange has a symmetry that facilitates its function. Said projection is capable of facing the hole, the flange being in the position of use or second position.
    [0067] In an alternative embodiment of the invention, the at least one flange is mechanically linked to the housing by a single longitudinal end of the at least one flange, where the mechanical link is suitable for tilting the at least one flange with respect to the housing from a First position to a second position. In this way the flange is able to move rotationally with a greater clearance from a first position to a second position.
    [0068]
    [0069] More specifically, the displacement of the at least one flange from the first position to the second position comprises a rotation between 3 ° and 15 °. Thus, a film hinge links the flange with the housing, the axis of rotation comprised in the plane generated by the same housing. In this second embodiment, the flange is secant with the housing and not arranged in the same plane of the housing, as described in the first embodiment.
    [0070]
    [0071] According to an alternative embodiment of the invention, the at least one flange has an arcuate profile, where the housing comprises a single clip, where the clip is disposed at a single longitudinal end of the at least one flange. In this way the flange is rotatably moved, from a first position to a second position, where it is fixed at its most distant end to the point from which it rotates.
    [0072]
    [0073] It should be mentioned that the at least one flange comprises a contact surface with the housing, where the contact surface is superimposed on at least one hole with the at least one flange being in the second position, so that the flange effects said closure. hole, said overlap presenting the required tightness against the entry of water and / or dirt from the environment.

    [0083]
    [0084] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0085]
    [0086] 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 described in detail below.
    [0087]
    [0088] Figure 1 illustrates, in an illustrative manner, a first rear perspective view and a second sectional view of the lighting device 1 for a vehicle, according to a first embodiment of the flange 5.
    [0089]
    [0090] In the first view of FIG. 1, the lighting device 1 can be seen, which comprises a housing 3 that protects the retroreflector 2. Said housing 3 comprises a plurality of fixing elements, for fixing said lighting module 1, for example , to a vehicle bumper.
    [0091]
    [0092] In the second sectional view of FIG. 1, the retroreflector 2 mechanically linked with a housing 3 can be seen. Said retroreflector 2 is supported all around its perimeter to the housing 3, by means of a projection. Said perimeter support allows the housing 3 to be connected to the retroreflector 2 by means of, for example, an ultrasonic joining process. Saying The joining process requires a continuous support surface, where said support surface is comprised in the same plane.
    [0093]
    [0094] Additionally, as can be seen in the section, between the housing 3 and the retroreflector 2 an air chamber 4 is defined, which is the space formed between the retroreflector 2 and the housing 3. In order to mitigate the problems described above, the housing 3 comprises at least one hole 31, wherein said hole 31 allows the air chamber 4 to communicate with the outside of the lighting device 1, particularly, allows to extract an existing air in the air chamber 4 in order to compensate for an existing overpressure inside the air chamber 4.
    [0095]
    [0096] In order to control the air that is extracted from the air chamber 4 or is added to the air chamber 4, the housing 3 comprises at least one flange 5. In the section shown in Figure 1, the flange 5 is located in its position of use or second position 55, where the flange 5 closes the hole 31. To achieve a suitable closure of the hole 31 and, additionally, a tightness of the lighting module 1, the flange 5 comprises a projection 52, intended to cover hole 31.
    [0097]
    [0098] The preferred embodiment of the present invention comprises a single hole 31 capable of being covered with a single flange 5, as seen in the second view. In said embodiment, the preferred solutions for mechanical bonding between the retroreflector 2 and the housing 3 is either an ultrasonic welding joint, or a vibration welding.
    [0099]
    [0100] More in detail, the retroreflector 2 can be a translucent plastic or crystal, in addition to the catadioptric element. That is to say, said retroreflector 2 comprises prisms either a geometry of faceted walls or optical structures on the inner surface of the retroreflector 2. The translucent plastic or glass performs a protective function of the catadioptric or retroreflective element 2.
    [0101]
    [0102] In Figure 2, it can be seen, illustratively, a first rear view and a second rear view of the lighting device 1 for a vehicle, with a first embodiment of the tab 5. In the first view, the tab 5 is in a second position 55 or use position. In the second view, said tab 5 is in a first position 54 or manufacturing position.
    [0103] In the same figure 2 it can be seen, in the second rear view, corresponding to the figure below on the right, a housing 3 that has an air inlet or outlet port 31 to the air chamber 4. As mentioned , in the first position 54 of the flange 5, this allows the passage of air through the hole 31. Thus, the housing 3 and the flange 5 form a single component, obtained from the same plastic injection process.
    [0104]
    [0105] In said second view of Figure 2, it can be seen that the flange 5 is attached to the housing 3 by means of two film hinges 53, arranged on the side and side of the flange 5. Additionally, the housing 3 comprises two clips 32, in which at least one longitudinal end 51 of the flange 5 is fixed, allowing the flange 5 to be retained in the second position 55. Additionally, the flange 5 also comprises at least one projection 52 to be inserted or positioned over the hole 31. The projection 52 is designed to have a geometry complementary to the geometry of the hole 31. Thus, if the hole 31 comprises an inclined wall in the form of a truncated cone, as can be seen in the sectional view of Figure 1, the projection 52 comprises a complementary form to said truncated cone shape.
    [0106]
    [0107] The geometry composed of two clips 32 and the hole 31 arranged in a middle area between the two clips 32, shown in Figure 2, allows to simplify the design and control the pressure exerted by the flange 5, in this case by the projection 52 of the tab 5, over the hole 31. Thus, the pressure from which the air in the air chamber 4 overcomes the force exerted by the projection 52 and can exit the air chamber 4 can be regulated more precisely. .
    [0108]
    [0109] As mentioned, the flange 5 is attached to the housing 3 by means of a film hinge 53. Said film hinge 53 allows a rotational displacement between a first position 54 or use position, of the first rear view of Figure 2, to a second position 55 or manufacturing position, shown in the second rear view of Figure 2.
    [0110]
    [0111] Specify that said embodiment requires at least one hinge film 53, which is subjected to a bending process by the operator from the injection position to the use position. Said film hinge 53 comprises a weakened one, that is, a smaller material thickness, in order to allow its folding function. In this assembly process, the operator must make a 180 ° rotation of the flange 5, so that the flange 5 is retained in the second position 55 by the two clips 32. In this first embodiment, the flange 5 is arranged in the same plane as the housing 3, so that the design of the injection machine is simplified.
    [0112]
    [0113] It is observed from this first embodiment, as the housing 3 comprises both the flange 5 linked to the housing 3 by means of at least one film hinge 53, at least one clip 32 for retaining the flange 5 in the second position 55. All This is obtained by means of the same injection process, without adding additional components that increase the price of the lighting module 1 or complicate the assembly and logistics process of said lighting module 1.
    [0114]
    [0115] In Fig. 3 an illustrative rear view of a second embodiment of the lighting device 1 can be seen, illustratively, which comprises a housing 3 that protects the retroreflector 2. Said housing 3 comprises a plurality of elements of fixing, to fix said lighting module 1, for example, to a vehicle bumper. The lighting module 1 also comprises an air chamber 4 defined between the retroreflector 2 and the housing 3.
    [0116]
    [0117] In order to control the air that is extracted from the air chamber 4 or is added to the air chamber 4, the housing 3 comprises a flange 5. In this second embodiment, the flange 5 swings from a single longitudinal end 51, in this case, the left longitudinal end 51 of Figure 3. In addition, the flange is held in the second position 55 by means of a clip 32, where the clip 32 is disposed in the housing 3. The clip 32 retains the longitudinal end 51 right of the flange 5.
    [0118]
    [0119] In Fig. 4A an illustrative sectional view of the second embodiment can be seen, illustratively, where the flange 5 is in a first open position 54, that is, without contacting the adjacent area of the housing 3 to the hole 31. Said first position 54 corresponds to an injection position, or an injection mold outlet. In general, it can be seen that the lighting device 1 comprises a retroreflector 2 connected to a housing 3, which has at least one hole 31 to avoid overpressure in the air chamber 4. In order to close said hole 31 the housing 3 comprises at least one flange 5, which can be fixed to the clip 32 by its longitudinal end 51. The flange 5, initially in a first position 54, is capable of moving to a second position 55, in which the projection 52 closes the hole 31. In said alternative embodiment, the presence of a hinge type film 53 connection is not essential, although it could be used, not being incompatible.
    [0120]
    [0121] In Fig. 4B an illustrative sectional view of the second embodiment can be seen, illustratively, where the flange 5 is in a second position 55 for use, that is, by contacting the adjacent area of the housing 3 to the hole 31. In the transition from the first manufacturing position 54 to the second operating position 55, the flange 5 swings between 3 ° and 15 °, contacting the housing 3 and covering the hole 31.
    [0122]
    [0123] In said second embodiment, as can be seen in the views in section 4A and 4B, the flange 5 comprises an arcuate geometry, so that a clip 32 holds a longitudinal end of the flange 5. Furthermore, the flange 5 it comprises a concave zone, said zone being the one that contacts the housing 3 and covers the hole 31. The flange 5 can also comprise a projection 52, the projection being the one that contacts the housing 3 and closes the hole 31.
    [0124]
    [0125] Preferably, the contact surface of the projection 52 is in an area closer to the clip 32 than to the mechanical link zone of the flange 5 with the housing. In this way, the hole 31 is more robustly blocked by being held closely by the clip 32.
    [0126]
    [0127] Both the first embodiment and the second embodiment described are based on the same principle, which is described below. Thus, a contact surface of the flange 5 closes a hole of the housing 31. The flange 5 is retained in its second position 55 by means of at least one clip 32. Thus, when the air enclosed in the air chamber 4 comprises a predetermined pressure, will exert a force on the flange 5 that will overcome the resistance exerted by the flange 5. Thus, the flange 5 will undergo a deformation, which will minimally open the orifice 31 allowing an extraction of air from the air chamber 4 outward. The predetermined pressure from which an air passage opening is initiated is defined based on a geometry of the flange 5 and the design of the at least one clip 32 that retains the flange 5. In any case, the predetermined pressure will be lower than that pressure of the closed air inside the air chamber 4 that produces a deformation of the retroreflector 2. If the pressure exerted by air it does not exceed the predetermined pressure, the tab 5 will not undergo any deformation, so it will close the air passage of the air chamber 4 outwards.
