    [0002] LIGHT GUIDE AND LIGHTING SYSTEM FOR A SIDE OF A VEHICLE
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The object of the present patent application is a light guide for a vehicle according to claim 1, which incorporates notable innovations and advantages, together with a lighting system on one side of a vehicle, according to claim 9.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The lighting devices of the current vehicles, specifically the pilots preferably arranged at the rear of the vehicle, not only emit light in the direction of the vehicle, thus generating the typical signaling functions such as intermittent, braking ... but also It seeks to generate light towards the side of the vehicle. The light generated towards said side normally meets design requirements. Getting the headlight to show some particular shape or design in said lateral area usually involves the use of additional parts or elements, generating an increase in assembly complexity, as well as an associated cost increase.
    [0011]
    [0012] In this regard, it is known from the state of the art, as disclosed in DE102005008634, a headlamp for vehicles with a reflector and a signaling element arranged on the side of the headlamp. The reflector is in charge of directing the light beams in the vehicle's direction of travel. Both devices are connected to each other by a light guide device, which transports the light from an input area to an output area. This document seeks to take advantage of light generated by a light emitter to, through light guides, illuminate a side area of the vehicle.
    [0013]
    [0014] Thus, and in view of the above, it is seen that there is still a need for an external lighting device for a vehicle that allows to display different logos, letters and symbols by means of a light guide, presenting the advantage of generating a lateral lighting with greater versatility of the illuminated element, without an increase in the components used.
    [0015]
    [0016] DESCRIPTION OF THE INVENTION
    [0017]
    [0018] The present invention consists of an exterior lighting device for a vehicle, specifically in its lateral area, in order to offer the possibility that a vehicle sign or badge is recognizable on the side of the vehicle in low light conditions. It is pursued that this objective is achieved by minimizing the number of additional components, and presenting the possibility of implementing a great versatility of designs, in the vehicle's own lighting and signaling system.
    [0019]
    [0020] Thus, the technical problem consists in illuminating a lateral area of the vehicle, preferably with a printed circuit board, where the printed circuit board is oriented perpendicular to the surface to be illuminated. Thus, the at least one light emitter used to illuminate the sign or badge, also emits the light in an orientation perpendicular to the surface to be illuminated.
    [0021]
    [0022] More particularly, the light guide comprises:
    [0023] - a light input surface capable of receiving a light emitted by at least one light emitter,
    [0024] - a light output surface,
    [0025] - a first reflection body facing the light input surface,
    [0026] - a second reflection body, where the first reflection body is configured to internally reflect the incident light towards the second reflection body, where the second reflection body is configured to internally reflect the incident light in a direction substantially perpendicular to the surface light output,
    [0027] - a plurality of optical structures arranged on the light output surface, where the plurality of optical structures are configured to extract the light from the light guide.
    [0028]
    [0029] The need to redirect, by means of the light guide, the light emitted by at least one light emitter towards the light output surface is highlighted. The reason is that the The light emitter is arranged on a printed circuit board, which will be oriented so that the light emitters arranged therein perform the usual functions of lighting or signaling the vehicle, normally emitting the light beams in the direction of advance of the vehicle. These lighting or signaling functions can be the flashing light, position light, stop light, reversing light, daytime lighting ... In order not to add additional elements to the system, it is sought to take advantage of the printed circuit board , which is arranged in an undesired orientation to illuminate the output surface of the light beams.
    [0030]
    [0031] The need to guide the light from the input surface to the output surface is observed, achieving high homogeneity and efficiency in the illumination of the output surface.
    [0032]
    [0033] Specify that, preferably, the output surface comprises a badge or logo and / or at least one letter, so that it is not about generating a beam of light that has the function of directly illuminating, but rather of a function Indirect lighting of a sign or badge, seeking that there are no areas of the element to be illuminated of different intensities.
    [0034]
    [0035] Note that by reflecting the light internally, it must be understood within the light guide, by internal reflection.
    [0036]
    [0037] A light guide means a massive solid material light guide, which obtains a homogeneous light transmission. The material of said light guide is high transmissivity optical polycarbonate, which is a lightweight material, and with high impact resistance, which minimizes the risk of possible breakage, in addition to allowing high light transmissivity inside the light guide, minimizing the losses inside.
    [0038]
    [0039] It should be mentioned that the first reflection surface or first reflection body (which has a perpendicular direction), has as its objective an opening or increase of the light beam section. With this it is sought that the light beams pass from a circular section to a rectangular section, allowing the dimensions of the object or element to be illuminated to be larger.
    [0040] The second reflection surface, or second reflection surface, comprises optics arranged along the entire internal reflection surface, facing the opening of an illuminated plane. The objective is to direct the light beams by changing their direction, at most 90 °. It includes facets of reflection, with the aim of directing the light towards said direction. The facets also aim to open the field, trying to make the light beams have no parallel directions between them.
    [0041]
    [0042] Thus, and according to a first embodiment in which the light beams of the light emitter are oriented at an angle less than 90 ° with respect to the plane formed by the output surface, only a first reflection surface would be necessary to open the field of light, and a second reflection surface to orient the light beams in a direction contained in said plane.
    [0043]
    [0044] Thus, the light guide comprises an initial sector disposed between the input surface and the first reflection body, where the initial sector comprises a substantially cylindrical geometry. This minimizes, or even cancels, the effect of loss of light beams. It should be mentioned that the light guide with cylindrical section is capable of collecting and driving all the light generated by the light emitter, preferably an LED. Remember that the light emitter emits a cone of light. In this way, guidance of all the light emitted by the light emitter to the first reflection surface is produced without loss of light beams.
    [0045]
    [0046] According to another aspect of the invention, the light guide comprises a final sector disposed between the second reflection body and the light output surface, where the final sector comprises a substantially rectangular prism geometry. In this way, the progressive opening of the light field is possible, by means of the different reflection surfaces, from a first cylindrical section, to a last rectangular section.
    [0047]
    [0048] Advantageously, the light guide comprises a second reflection body with a plurality of optical elements, where the plurality of optical elements are arranged along the second reflection body. In this way, greater efficiency in the transmission of light by the light guide is achieved, and a better orientation towards the exit surface.
    [0049] Alternatively, according to a second embodiment, the light beams of the light emitter are oriented at an angle greater than 90 ° with respect to the plane formed by the output surface. In said embodiment, a third reflection surface is required, in addition to the first reflection surface and the second reflection surface, which allows the light beams to be oriented according to the desired direction, as explained in greater detail below.
    [0050]
    [0051] Thus, in said second embodiment, the light guide comprises a third reflection body disposed between the first reflection body and the second reflection body. This increases the reorientation performance of the light within the light guide.
    [0052]
    [0053] Note that the third reflection body, or third reflection surface, comprises a series of optics arranged along the entire internal reflection surface, in order to maximize homogeneity in the illuminated plane. Thus the objective is to direct the light beams by changing their direction, at most 90 °. It includes facets of reflection, with the aim of directing the light towards said direction. The facets also aim to open the field, trying that the light beams do not have parallel directions between them, thus generating a homogeneous distribution of the light beams.
    [0054]
    [0055] Specify that the light guide has three reflection surfaces. These three reflection surfaces exist due to the orientation of the printed circuit board, or also due to the direction of emission of the light emitter or LED, with respect to the surface to be illuminated, or output surface. Thus we have; a first reflection body or first reflection surface to open the field; a second reflection body or second reflection surface to reorient the light beams; and a third reflection body or third surface to direct the light towards the light extraction or exit surface.
    [0056]
    [0057] According to another aspect of the invention, the third reflection body of the light guide comprises a plurality of optical elements, where the plurality of optical elements are arranged along the third reflection body. In this way the homogeneity of the light beams that affect the exit surface is improved, while a better orientation and distribution of said light beams is achieved.
    [0058]
    [0059] Note that the output surface comprises a plurality of optical structures, in order to extract the light from the light guide. Preferably they are microcones or laser engraved on the outer surface of the light guide, in order to extract the light at the desired points. In this way the desired sign or badge can be generated, from beams of light that run substantially perpendicular to the direction of exit.
    [0060]
    [0061] More particularly, the plurality of optical structures are prisms and / or cones and / or reliefs generated on the light output surface, thereby improving the distribution of light beams reflected by internal reflection.
    [0062]
    [0063] It is also an object of the present invention, a lighting system on one side of a vehicle, where the lighting system comprises:
    [0064] - a printed circuit board,
    [0065] - at least one light emitter arranged on the printed circuit board, and
    [0066] - a light guide as described above, where the light guide receives the light emitted by the at least one light emitter, where the light guide comprises a light output surface, where the printed circuit board is substantially comprised in the foreground and where the light output surface of the light guide is substantially comprised in the background, where the foreground and the background are secant.
    [0067]
    [0068] Said lighting system is oriented, in the same way as the light guide, to efficiently extract the light from the light guide, and to enable the recognition of a device by sharing a plurality of components intended for signaling and lighting in the direction of vehicle advance.
    [0069]
    [0070] According to another aspect of the lighting system of the present invention, the foreground is secant with the light output surface of the light guide, that is, a projection of the printed circuit board cuts with the output surface of the guide of light. The need to reorient the light beams from the emission to the output surface is observed.
    [0071]
    [0072] Specify that the cut with the light output surface is just for the area to be illuminated. In this regard, the light has to make various changes of direction in order to illuminate the output surface. Note that the at least one light emitter emits light in a direction substantially perpendicular to the foreground or plane formed by the printed circuit board. Said printed circuit board is substantially flat and is comprised in a close-up or slightly curved area. The area to be illuminated is comprised in the background, the foreground and the background being drying.
    [0073]
    [0074] In a preferred embodiment of the invention, the at least one light emitter of the lighting system is a single LED. In this way the light can be controlled and directed very well towards the first surface or body of reflection, also minimizing the energy consumption and the additional elements to be implemented in the printed circuit board.
    [0075]
    [0076] Specify that, in a variant of the lighting system of the present invention, there is a printed circuit board with a light emitter or LED that generates a first function and, on the other hand, a single light emitter or LED that generates a second function. The light emitter or LED that generates a first function is preferably oriented in a forward direction of the vehicle.
    [0077]
    [0078] According to another aspect of the invention, the lighting system comprises at least one additional lighting source arranged on the printed circuit board, where the at least one first light emitter emits light in a direction opposite to the direction of light emission of the At least one source of lighting.
    [0079]
    [0080] Or in other words, the at least one first light emitter emits light in a first direction and the at least one source of illumination emits light in a second direction, where the first direction and the second direction are equal but both emit light in opposite directions: one in the forward direction of the vehicle and one in the reverse direction of the vehicle.
    [0081]
    [0082] Additionally, the at least one first light emitter generates a first lighting function and the at least one lighting source generates at least a second lighting function. In this way the lighting performance is extended, and the information to be presented.
    [0083]
    [0084] Detail that the second functions generated are the signaling functions, such as intermittent, braking, front lighting, fog, daylight, reverse light ... These lighting functions are used both in headlights and in vehicle pilots.
    [0085] On the other hand, the light guide of the lighting system comprises a positioning means, where the positioning means is configured to locate the light guide relative to the printed circuit board. In this way it is possible to fix and center the light guide with respect to the printed circuit board precisely and quickly. Specifically, the positioning means regulates the distance between the light input surface and the printed circuit board.
    [0086]

Other features and advantages of said light guide and lighting system of a side of a vehicle, object of the present invention, will be apparent from the description of a preferred, but not exclusive, embodiment illustrated by way of example. limiting in the accompanying drawings, in which:

    [0097] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0098]
    [0099] 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.
    [0100]
    [0101] In Figure 1, it can be seen, illustratively, a side view of a vehicle 1 with a lighting system, specifically a headlight 2. For the description of the present invention, reference is made to the headlight 2 or pilot provided in the left rear of the vehicle 1. Alternatively, it could be implemented in both the right rear headlight 2 and the previous vehicle headlights 2. In said figure 1 it can be seen how the headlight 2 emits mainly light in the forward direction of the vehicle 1 and, in this particular case, in the opposite direction to the forward one. In particular, the headlight 2 is configured to signal backwards of the vehicle 1 functions such as braking, the activation of a turn signal, the activation of the rear fog light ... Traditionally, no light is emitted towards the sides of the vehicle 1. The present invention seeks to generate lighting, preferably of low intensity on said lateral surface of the headlamp 2, in order to illuminate a badge or sign.
    [0102]
    [0103] Figure 2 shows, in an illustrative way, a detail view for a lighting system, or headlight 2 of a vehicle 1. Specifically, the side area of the headlight 2 of the present invention is shown, which comprises an emitter of light 3, mounted on a printed circuit board 4, and oriented towards a light guide 5, which transmits the light to an optical structure 61 of an output surface 6. The optical structure 61 is responsible for extracting the light in the exit surface 6 generating the symbol or badge to be illuminated on said side of the vehicle 1.
    [0104]
    [0105] The lighting system of the present invention seeks to generate synergies with the components that form a headlight 2, in order to generate additional illumination towards the side of the vehicle 1. For this, the headlight 2 is composed of a printed circuit board 4 , where the main surface of the printed circuit board 4 is arranged substantially parallel to the light extraction surface of the headlamp 2, that is, said main surface will be substantially perpendicular to the direction of travel of the vehicle 1. Thus, the Lighting sources 8 will be oriented directly towards the light extraction surface of the headlamp 2. The main surface of the printed circuit board 4 is understood as comprising the electronics, the LEDs, the cooling and connection elements.
    [0106]
    [0107] Thus, as can be seen in Figure 2 or, in greater detail, in Figure 4A, the printed circuit board 4 comprises a plurality of lighting sources 8 oriented towards the rear area of the vehicle 1. It is observed that any light source 8 mounted on the printed circuit board 4 will not be oriented towards the side of the vehicle 1, so it is necessary to reorient the light beams generated by means of the guide light 5 of the present invention.
    [0108]
    [0109] Thus, as can be seen in Figure 4A, the lighting system according to the present invention has a printed circuit board 4 arranged substantially in the foreground. It is noted that the printed circuit board 4 is solid but may comprise a slight curvature. On the other hand, the lighting system comprises a light guide 5 with an exit surface 6 of the light. The output surface 6 is substantially in the background. It is noted that the exit surface 6 may comprise a slight curvature. Said first plane and said second plane are secant, that is, the two planes are cut in a line.
    [0110]
    [0111] By secant planes it is understood that they are not substantially parallel. Particularly, the angle formed between the first plane and the second plane is between 45 ° and 135 °. The need to reorient the beam of light emitted by the LEDs becomes evident.
    [0112]
    [0113] According to a preferred embodiment of the present invention, the first plane and the second plane are drying on the light outlet surface 6 of the light guide 5. That is, the first plane and the second plane are cut in a line, where the line is partially included in the light output surface 6. Thus, an extension of the printed circuit board 4 would cut with the light output surface 6.
    [0114]
    [0115] In particular, the printed circuit board 4 comprises a plurality of lighting sources 8, where the lighting sources 8 are arranged on a first surface of the printed circuit board 4. Said lighting sources 8 perform at least a second function of lighting, such as braking, intermittence ...
    [0116]
    [0117] On the other hand, the printed circuit board 4 comprises at least one light emitter 3 arranged on a second surface of the printed circuit board 4. The at least one light emitter 3 is configured to perform a first lighting function, in specifically, the indirect lateral illumination of the sign or distinctive object of the present invention. It is thus observed that the light emitter 3 is completely disconnected from any common lighting or signaling function of the vehicle 1. The light emitter 3 is particularly a single LED, where the light emitter 3 emits light in a direction opposite to that of the lighting sources 8. It is noted that, depending on the position of the printed circuit board 4 with respect to the output surface 6 of the light guide 5, the light emitter 3 and the plurality of lighting sources 8 can emit in the same direction.
    [0118]
    [0119] The reorientation of the light beams emitted by the light emitter 3 will be carried out by means of the light guide 5. Said light guide can be seen in greater detail in Figures 3, 4A, 4B, 5 and 6.
    [0120]
    [0121] In Fig. 3 an illustrative perspective view of a light guide 5 of a lighting system for a vehicle 1 can be seen, illustratively, comprising a light emitter 3 oriented towards a light guide 5, which comprises a first reflection body 51, a second reflection body 52, and a third reflection body 54. The configuration of the first reflection body 51, the second reflection body 52 and the third reflection body 54 allow the beams of light to the exit surface 6.
    [0122]
    [0123] In particular, the first reflection body 51 will allow the light beams to be oriented towards the second reflection body 52. Additionally, the second reflection body 52 will allow the light beams to be oriented towards the third reflection body 54. It is emphasized that the beams of light are transmitted by internal reflection inside the light guide 5.
    [0124]
    [0125] Additionally, the output surface comprises at least one optical structure 61, where the optical structure 61 is configured to remove the light beams from the light guide 5. The optical structures 61 will be distributed on the output surface 6 generating the sign or distinctive to illuminate.
    [0126]
    [0127] Additionally, the light guide 5 comprises an initial sector 56, which is configured to receive the light emitted by the at least one light emitter 3, and a final sector 53, where the light output surface 6 is located. A further objective of the present invention is to modify the conical structure of the light beams emitted by the light emitter 3, thus illuminating an output surface 6 of totally different geometry and dimensions.
    [0128]
    [0129] Figure 4A shows in more detail the orientation of the printed circuit board 4 with respect to the output surface 6 to be illuminated. In order to improve positioning Between the light guide 5 and the printed circuit board 4, the light guide 5 comprises a positioning means 57, so that the positioning means 57 allows to center and position the light guide 4 with respect to the light emitter 3. In particular , the positioning means 57 is configured to control a distance between the input surface of the light guide 5 with respect to the light emitter 3. Both the distance between both elements and the centering are especially important to improve the efficiency of the assembly and reduce the light beam losses. The positioning means 57 is obtained from the same injection mold as the light guide 5.
    [0130]
    [0131] In figure 4B it is shown that the light guide 5 comprises an initial sector 56 configured to receive the light beams emitted by the light emitter 3. The initial sector 56 comprises a cylindrical geometry, that is to say of circular section. The axis of the cylinder substantially coincides with the emission axis of the light emitter 3. The cylindrical geometry is especially advantageous in preventing light losses and directing the light beams towards the first reflection body 51. The first reflection body 51 is a inclined plane of reflection that directs the light beams in a substantially perpendicular direction.
    [0132]
    [0133] In addition, the light guide comprises a final sector 53, where the final sector 53 is arranged in the area of the exit surface 6. The section of the final sector 53 is rectangular, thus allowing the sign or badge included in the output surface 6 has larger dimensions.
    [0134]
    [0135] In the frontal perspective of Figure 5, the geometry adopted by the optical structures 61 that generate the sign or badge to be illuminated can be observed, and any other geometry can be adopted. Additionally, the second reflection body 52 is observed in detail, which allows the light to be oriented towards the exit surface 6. In particular, the second reflection body 52 is an inclined plane of reflection, which allows to reorient the light beams at most 90 °. Additionally, the second reflection body 52 is elongated, whereby it allows to open the illuminated plane within the light guide 5. Optionally, the second reflection body 52 comprises a plurality of optical elements 55, where said optical elements 55 are, according to a particular embodiment, reflection facets, which are configured to generate diffuse reflection, so that the light beams are not emitted in a homogeneous or parallel way to the output surface 6.
    [0136] On the other hand, in the rear perspective view of Figure 6, the third reflection body 54 can be observed in detail, which allows the light to be oriented towards the second reflection body 52. In particular, the third reflection body 54 is an inclined plane of reflection, which allows reorienting the light beams at a maximum 90 °. Optionally, the third reflection body 54 comprises a plurality of optical elements 55, such as those described above to improve the homogeneity of the light beams transmitted by internal reflection inside the light guide 5.
    [0137]
    [0138] It is noted that each reflection surface or body 51, 52, 54 can change the direction of the light beams a maximum of 90 °, so, according to the arrangement of the light emitter 3, and therefore its emission direction , and the position of the light output surface 6, a particular distribution of the reflection body is necessary. Thus, if the inclination between the first plane, which comprises the printed circuit board 4, and the second plane, which comprises the light output surface 6, is less than 90 °, the implementation in the light guide of the third body Reflection 54 is optional. On the contrary, if the inclination between the first plane and the second plane is greater than 90 °, the implementation in the light guide of the third reflection body 54 becomes essential. The angles quoted between foreground and background have been calculated taking as reference the surface of the foreground where the light emitter 3 is located and the surface of the second plane opposite to where the exit surface 6 is located.
    [0139]
    [0140] According to a preferred embodiment of the invention, the light guide 5 has a plurality of optical structures 61 that can be prisms and / or cones and / or reliefs generated in the light output surface 6. Said optical structures 61 can be obtained through a laser engraving process of the output surface 6. Said optical structures 61 will make it possible to redirect the light beams reflected in the second reflection body 52 towards a lateral direction of the vehicle. As shown in the figures, the light beams that are transmitted by the final sector 53 affect the optical structures 61, generating an illuminated element in the output surface 6.
    [0141]
    [0142] On the other hand, specify that the plane of the exit surface 6 may comprise a certain curvature for design reasons, but in essence they form a basically flat structure.
    [0143]
    [0144] The details, shapes, dimensions and other accessory elements, as well as the components used in the implementation of the light guide and lighting system of one side of a vehicle may be conveniently replaced by others that are technically equivalent, and do not depart from the essentiality of the invention or the scope defined by the claims that are included following the following list.
