Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automotive headlamp illumination. Specifically, it relates to a lighting structure for the III area of a vehicle lamp, a condenser for the vehicle lamp, an automotive lighting module, and an automobile. Background Art
[0002] With the application of condensers in the low beam or high beam technical fields of automotive headlamps, the III area, as an important part of the low beam light pattern and also an important part of the headlamp light distribution required by regulations, the technical solutions for III area lighting in vehicle lamps containing condensers have correspondingly achieved certain innovation and development.
[0003] The closest prior art to the present invention can refer to Chinese invention patent CN106122870B. This patent discloses a technical solution for a lighting structure in the III area of a vehicle lamp. The lighting device for the III area is arranged on the upper surface of the condenser and is a stepped structure with a certain height. The incident light surface is higher than the upper surface of the condenser. The longitudinal section of this structure in the III area is triangular and gradually transitions from back to front along the light-emitting direction to the light-emitting surface. Light enters from the incident light surface of the III area, is adjusted by the incident light surface, and finally exits from the light-emitting surface to form the light pattern corresponding to the III area of the vehicle lamp. However, this technical solution still needs to be further improved: (1) This III area structure has a greater impact on the light path of the high beam because the upper surface of the condenser is set as the total reflection surface of the high beam light. The III area structure is arranged on the upper surface and is integrally set with the upper surface, which destroys the upper surface of the condenser that was originally the total reflection surface of the high beam light and has a certain impact on the performance of the high beam; (2) The adjustment of the III area light pattern is not fine enough. Because the incident light surface of the III area in this solution is a relatively large arc surface, it can adjust the overall illumination intensity of the III area light pattern, but it cannot well adjust the local area of the III area light pattern. The structure for adjusting the local area of the III area light pattern in this invention is a hole-like structure arranged locally on the incident light surface, and this structure has limited ability to adjust the light pattern.
[0004] There is an urgent need in this technical field to provide a new technical solution to solve the above technical problems. Summary of the Invention
[0005] In order to overcome the deficiencies of the prior art, the basic technical problem that the present invention first needs to solve is to provide a lighting structure for the III area of a vehicle lamp, which has the advantages of fine adjustment of the III area light pattern and little impact on the high beam light pattern.
[0006] The present invention also provides a condenser for a vehicle lamp including this lighting structure for the III area of the vehicle lamp, an automotive lighting module including this condenser for the vehicle lamp, an automotive lighting device including this automotive lighting module, and an automobile including this automotive lighting device.
[0007] To achieve the above object, on the one hand, the present invention provides a lighting structure for the III area of a vehicle lamp, including a light incident part for the III area and a light exiting part for the III area arranged in sequence along the light incident direction. The light incident part for the III area includes at least two light transmissive sheets distributed in the horizontal direction. Each light transmissive sheet includes a light incident surface for the III area, and the structure of the light transmissive sheet is adapted to form a light expansion profile. The normal direction of the light incident surface for the III area faces the light exiting part for the III area; the light forming the III area is incident on the light incident surface for the III area, diffused by the light incident surface for the III area and then irradiated towards the light exiting part for the III area, and finally exits through the light exiting part for the III area.
[0008] Preferably, the light transmissive sheet is an inner concave curved surface structure or an outer convex curved surface structure. The light expansion profile includes a horizontal expansion profile for the III area and / or an up-and-down expansion profile for the III area. The horizontal expansion profile for the III area is formed by the cross-sectional profile of the light transmissive sheet in the horizontal direction, and the up-and-down expansion profile for the III area is formed by the cross-sectional profile of the light transmissive sheet in the up-and-down direction.
[0009] Preferably, the horizontal expansion profile for the III area and / or the up-and-down expansion profile for the III area is an arc line with a radius R≤5mm.
[0010] Preferably, the plurality of light transmissive sheets are arranged continuously in sequence or discontinuously.
[0011] Preferably, the size of the light incident surface for the III area in the horizontal direction and / or the up-and-down direction is 0.5 - 2mm.
[0012] Preferably, the light exiting part for the III area is an inner concave arc surface structure with continuous curvature.
[0013] On the second aspect, the present invention provides a condenser for a vehicle lamp, including a high beam light incident part, an oblique reflection surface, an upper surface, and a front and rear light channel, and further including the above-mentioned lighting structure for the III area of the vehicle lamp.
[0014] Preferably, one end of the oblique reflection surface is connected to the high beam light incident part, and the other end is connected to the upper surface of the condenser; the light incident part for the III area is arranged on the upper surface of the oblique reflection surface close to the upper surface of the condenser, and the light exiting part for the III area is arranged at one end of the upper surface of the condenser far from the oblique reflection surface; the front and rear light channel is arranged between the light exiting part for the III area and the oblique reflection surface.
[0015] Preferably, the high beam light incident part includes at least one condenser cup-shaped structure. The middle of the condenser cup-shaped structure is an inner concave cavity, and the cross-sectional contour of the outer side gradually increases along the light exiting direction; the normal direction of the light incident surface of the high beam light incident part is the up-and-down direction.
[0016] Preferably, the headlight condenser further includes a 50L dark area forming structure and / or a cut-off line forming structure. The 50L dark area forming structure is disposed in the middle of the front end of the upper surface of the condenser, and the cut-off line forming structure is disposed at the intersection of the upper surface of the condenser and the light output portion of Zone III.
[0017] Preferably, the high-beam light input portion, the oblique reflection surface, the upper surface of the condenser, and the front and rear light channels are integrally formed, and the headlight condenser is formed of transparent plastic, silicone, or glass.
[0018] A third aspect of the present invention provides an automotive lighting module, including a high-beam circuit board, a reflector, a low-beam circuit board, a lens, and the above-mentioned headlight condenser.
[0019] A fourth aspect of the present invention provides an automotive lighting device, including the above-mentioned automotive lighting module.
[0020] A fifth aspect of the present invention provides an automobile, including the above-mentioned automotive lighting device.
[0021] Through the above technical solutions, the beneficial effects of the present invention are as follows:
[0022] 1. The lighting structure of Zone III of the headlight adjusts the light pattern of Zone III more precisely. Because the light input surface of the lighting structure of Zone III of the headlight of the present invention is provided with a plurality of light-transmitting sheets that expand light rays in the horizontal and / or vertical and horizontal directions, the light patterns corresponding to these plurality of light-transmitting sheets with smaller areas are jointly spliced and superimposed to form the light pattern of Zone III, so that the light pattern of Zone III is divided more finely, and the light pattern of Zone III can be adjusted more precisely;
[0023] 2. When the lighting structure of Zone III of the headlight is applied to the headlight condenser, the light input portion of Zone III is disposed on the oblique reflection surface and near the connection between the oblique reflection surface and the upper surface of the condenser. Such a setting enables the light ray channels of Zone III and the light ray channels of the high beam to share, without damaging the upper surface that functions as a total reflection for the high beam, and has a relatively small impact on the high beam light pattern.
[0024] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] 005 Lens Detailed implementation manners
[0052] The following is a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present invention, and the protection scope of the present invention is not limited to the following specific implementation manners.
[0053] In the description of the present invention, it should be explained that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connection" and "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the present invention, the normal direction refers to the direction or straight line perpendicular to a certain surface. The normal direction of the light incident surface 101 in Region III is to indicate that the light incident surface 101 in Region III is arranged facing the light emitting portion 2 in Region III. When the light incident surface 101 in Region III is set as a concave curved surface or a convex curved surface structure, the normal direction representing the light incident surface 101 in Region III refers to the normal direction of the center point of the curved surface. If the center point of the curved surface is difficult to determine, the focus of the straight line formed by the intersection of the upper and lower bisecting planes and the horizontal bisecting plane of the curved surface and the curved surface is used as the center point.
[0055] A headlight illumination structure in Region III provided by the first aspect of the present invention is as Figures 1 - 8 shown, including a light incident portion 1 in Region III and a light emitting portion 2 in Region III arranged in sequence along the light incident direction. The light incident portion 1 in Region III includes at least two light transmissive sheets 10 distributed in the horizontal direction. Each light transmissive sheet 10 includes a light incident surface 101 in Region III, and the structure of the light transmissive sheet 10 is adapted to form a light expansion profile. The normal direction of the light incident surface 101 in Region III faces the light emitting portion 2 in Region III; the light forming Region III is incident on the light incident surface 101 in Region III, diffused by the light incident surface 101 in Region III and then irradiated towards the light emitting portion 2 in Region III, and finally emitted through the light emitting portion 2 in Region III.
[0056] It should be noted that in the present invention, several light transmissive sheets 10 can be arranged horizontally in a "one" shape. Those skilled in the art can also make slight millimeter-level deviations of each light transmissive sheet 10 in the up and down directions while basically maintaining the arrangement in the horizontal direction in sequence, which belongs to the conventional substitution of those skilled in the art and also falls within the protection scope of the present invention. In addition, the structure of the light transmissive sheet 10 adapted to form a light expansion profile can be concave, convex, or other structures that can achieve the same technical effect. The normal direction of the light incident surface 101 in Region III faces the light emitting portion 2 in Region III, indicating that the light incident surface 101 in Region III is arranged facing the light emitting portion 2 in Region III, so that the light entering the light incident surface 101 in Region III can be diffused and then irradiated towards the light emitting portion 2 in Region III.
[0057] Through the lighting structure of the third area of the vehicle lamp according to the above basic technical solution of the present invention, during use, the light incident part 1 of the third area and the light exit part 2 of the third area are installed on the condenser of the vehicle lamp, and the light incident part 1 of the third area and the light exit part 2 of the third area are arranged in sequence along the light incident direction, so that the light forming the third area is incident on the light incident surface 101 of the third area. The light incident surface 101 of the third area diffuses the incident light and irradiates it towards the light exit part 2 of the third area, and finally exits through the light exit part 2 of the third area.
[0058] As an embodiment of the present invention, the light-transmitting sheet 10 is an inner concave curved surface structure or an outer convex curved surface structure. The light expansion profile includes a horizontal expansion profile 102 of the third area and / or a vertical and horizontal expansion profile 103 of the third area. The horizontal expansion profile 102 of the third area is formed by the cross-sectional profile of the light-transmitting sheet 10 in the horizontal direction, and the vertical and horizontal expansion profile 103 of the third area is formed by the cross-sectional profile of the light-transmitting sheet 10 in the vertical and horizontal directions. The horizontal expansion profile 102 of the third area enables the incident light of the third area to be angularly expanded in the horizontal direction, and the vertical and horizontal expansion profile 103 of the third area enables the incident light of the third area to be angularly expanded in the vertical and horizontal directions to meet the requirements of the lighting range of the third area. It should be noted that those skilled in the art can set the expansion profile only in one of the horizontal or vertical and horizontal directions according to needs, so that the light corresponding to the third area is expanded only in one of the directions, which also belongs to the protection scope of the present invention.
[0059] In the present invention, the horizontal expansion profile 102 of the third area and / or the vertical and horizontal expansion profile 103 of the third area can be set as arcs. Preferably, the horizontal expansion profile 102 of the third area and / or the vertical and horizontal expansion profile 103 of the third area are arc lines with a radius R≤5mm, which can effectively angularly expand the light of the third area in both the horizontal and vertical and horizontal directions to adjust the lighting range and lighting intensity of the third area. Specifically, the horizontal expansion profile 102 of the third area and / or the vertical and horizontal expansion profile 103 of the third area can be set as arc lines with a radius R = 2mm.
[0060] As an embodiment of the present invention, multiple light-transmitting sheets 10 are arranged continuously or discontinuously in sequence. In the present invention, several light-transmitting sheets 10 can be set to have 2, 3, 7 or 8 separate light incident areas, but are not limited to these distribution methods. Those skilled in the art can also set the light-transmitting sheets 10 in other forms such as being closely connected.
[0061] As an embodiment of the present invention, the size of the light incident surface 101 in the III region in the horizontal direction and / or the up-and-down direction is 0.5-2 mm. The small-area light incident surface 101 in the III region can further reduce its influence on the high beam light pattern, avoiding the influence of an overly large III-region structure on the high beam light pattern. Sizes within the range of 0.5-2 mm can achieve the corresponding technical objectives and obtain the corresponding technical effects. If the size of the light incident surface 101 in the III region in the horizontal direction and / or the up-and-down direction is less than 0.5 mm, it is difficult to obtain a suitable illumination range for the III region, and it is also difficult to achieve in terms of technology; if it is greater than 2 mm, the influence it causes on the high beam light pattern is greater than that caused by less than 2 mm. Specifically, the size of the light incident surface 101 in the III region in the horizontal direction and / or the up-and-down direction can be set to 1 mm, which can not only meet the accuracy requirements of the manufacturing process but also reduce the influence on the high beam light pattern. In the present invention, the areas of the respective light-transmitting sheets 10 are basically equal, but this does not mean that their areas must be equal. Technical solutions in which the areas can be set to be unequal under the condition of conforming to the above-mentioned size parameter limitations belong to the protection scope of the present invention.
[0062] As an embodiment of the present invention, the light-emitting portion 2 in the III region is a concave arc surface structure with continuous curvature, which can further expand the angle of the emitted III-region light. The reason for setting it with continuous curvature is that the light-emitting portion 2 in the III region is used as the light-emitting surface, preventing uneven light patterns in the III region caused by discontinuous curvature.
[0063] From the above description, it can be seen that the advantage of the III-region lighting structure of the vehicle lamp of the present invention is that by setting the light incident surface 101 in the III region as a plurality of light-transmitting sheets 10 that expand light in the horizontal and / or up-and-down directions, the light patterns corresponding to these plurality of small-area light-transmitting sheets 10 are jointly spliced and superimposed to form the III-region light pattern, making the III-region light pattern more refined and enabling more refined adjustment of the III-region light pattern. The light path for forming the III-region light pattern using this III-region lighting structure of the vehicle lamp is as Figures 9 - 11 shown. From the schematic diagram of the light path in the top-down direction from the D perspective, it can be seen that the light passing through the III region forms an angular range that expands horizontally to both sides in the horizontal direction. From the schematic diagram of the light in the side view direction from the E perspective, it can be seen that the light in the III region forms an angular range that expands to both the upper and lower sides, especially downward, in the up-and-down direction. According to vehicle lamp regulations such as GB25991 or ECE R112, there are many test positions such as P1, P2, P3, P4, P5, P6, P7, P8, B50L, and HV in the III region of the low beam. By finely designing the III-region lighting structure, the local adjustable ability of the III region can be improved, making the adjustment of the III region more controllable and more refined.
[0064] Based on the above-mentioned lighting structure of the III area of the vehicle lamp in the present invention, the second aspect of the present invention provides a vehicle lamp condenser, which includes a high beam light incident part 3, an inclined reflection surface 4, an upper surface 5 of the condenser, and a front-back light channel 6, and also includes the above-mentioned lighting structure of the III area of the vehicle lamp.
[0065] Further, as Figures 12 - 15 shown, one end of the inclined reflection surface 4 is connected to the high beam light incident part 3, and the other end is connected to the upper surface 5 of the condenser; the light incident part 1 of the III area is arranged on the upper surface of the inclined reflection surface 4 on the side close to the upper surface 5 of the condenser, and the light output part 2 of the III area is arranged at the end of the upper surface 5 of the condenser away from the inclined reflection surface 4; the front-back light channel 6 is arranged between the light output part 2 of the III area and the inclined reflection surface 4. After the light emitted by the high beam light source is incident through the high beam light incident part 3, it irradiates onto the inclined reflection surface 4, and after total reflection by it, a part of the light directly exits from the light output part 2 of the III area after passing through the front-back light channel 6, and the other part irradiates onto the upper surface 5, and after total reflection by it, it exits from the light output part 2 of the III area again. The light in the III area and the light of the high beam share the front-back light channel 6, rather than separately setting a channel for the light in the III area, avoiding an excessive impact on the high beam light pattern.
[0066] As an implementation manner of the present invention, the high beam light incident part 3 includes at least one condenser cup-shaped structure, the middle of the condenser cup-shaped structure is a concave cavity, and the outer contour cross-section gradually increases along the light output direction; the normal direction of the light incident surface of the high beam light incident part 3 is the up-down direction.
[0067] As an implementation manner of the present invention, the vehicle lamp condenser further includes a 50L dark area forming structure 7 and / or a cut-off line forming structure 8, the 50L dark area forming structure 7 is arranged in the middle of the front end of the upper surface 5 of the condenser, and the cut-off line forming structure 8 is arranged at the intersection of the upper surface 5 of the condenser and the light output part 2 of the III area. This vehicle lamp condenser is used not only for the formation of the light pattern in the III area and the high beam light pattern, but also for the formation of the 50L dark area and the cut-off line in the low beam light pattern in the high-low beam integrated vehicle lighting module.
[0068] As an implementation manner of the present invention, the high beam light incident part 3, the inclined reflection surface 4, the upper surface 5 of the condenser, and the front-back light channel 6 are integrally formed, improving the structural stability of the vehicle lamp condenser and avoiding the deviation of the light pattern caused by the installation and fixation between components; the vehicle lamp condenser is formed by transparent plastic, silica gel or glass, and specifically can be polycarbonate (PC) or polymethyl methacrylate (PMMA), making use of the common properties of transparency and light transmission of such materials.
[0069] Based on the above-mentioned vehicle lamp condenser of the present invention, the third aspect of the present invention provides a vehicle lighting module, as Figure 16As shown, it includes a high-beam circuit board 002, a reflector 003, a low-beam circuit board 004, and a lens 005, and further includes the above-mentioned vehicle headlight condenser 001. Those skilled in the art can clearly and uniquely determine that the lighting module is also provided with components such as a radiator and a lens bracket, which will not be described one by one here. A vehicle lighting module refers to a device or unit provided in a vehicle headlight for low-beam and / or high-beam lighting. As Figure 17 shown, the light emitted by the low-beam light source provided on the low-beam circuit board 004 is reflected by the reflector 003 and serves as the incident light of the light incident part 1 of area III on the condenser 001. After the light is emitted from the light exit part 2 of area III, it enters the lens 005 and is irradiated forward by the lens 005 to form the light pattern of area III.
[0070] Based on the above-mentioned vehicle lighting module of the present invention, in the fourth aspect of the present invention, a vehicle lighting device is provided, including the above-mentioned vehicle lighting module.
[0071] In the fifth aspect of the present invention, a vehicle is provided, including the above-mentioned vehicle lighting device. Therefore, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments of the vehicle headlight area III lighting structure, which will not be elaborated here.
[0072] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, including any suitable combination of each specific technical feature. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods. But these simple modifications and combinations should also be regarded as the content disclosed by the present invention and fall within the protection scope of the present invention.
