Description
Technical Field
[0001] The utility model relates to lighting equipment, and particularly to a lighting module, a high and low beam integrated module and a vehicle lamp. Background Art
[0002] In the existing lighting module, an LED light source 100 is adopted as the light source. Refer to Figure 1 , the theoretical light-emitting direction of the LED light source is the Z-axis, and the light pattern shape can be well controlled. Therefore, when arranging the LED light source, the optical axis of the LED light source is arranged corresponding to the reflecting surface of the reflecting element, so that the light rays reflected by the reflecting surface are projected by the lens to form a light pattern. However, refer to Figure 2 , there is a certain difference between the actual light-emitting direction and the theoretical light-emitting direction of the LED light source. When the theoretical light-emitting direction of the LED light source is perpendicular to the system light-emitting direction, due to the direct emission of the LED light source, stray light biased towards the Y-axis is generated, and this stray light will be directly projected by the lens without being reflected by the emitting element. Refer to Figure 3 and Figure 4 for comparison. This stray light will directly appear in the dark area above the light pattern, thus affecting the light pattern forming quality.
[0003] Therefore, it is necessary to design a lighting module to overcome or alleviate the above technical problems. Summary of the Utility Model

[0047] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and interpreting the present utility model, and the protection scope of the present utility model is not limited to the following specific implementation manners.
[0048] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, the terms "installation" and "connection" 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 utility model can be understood according to specific situations.
[0049] In the present utility model, unless otherwise stated, the orientation terms such as "above, below, left, right, front, back" usually refer to the positional relationship of the vehicle lamp during actual use. Exemplarily, when the vehicle lamp is arranged at the rear of the vehicle and emits light towards the rear of the vehicle, the direction pointed by the vehicle head is the rear, the direction pointed by the vehicle tail is the front, and "above", "below", "left", and "right" are the positional relationships determined based on the "front" and "back" positional relationships.
[0050] The first aspect of the present utility model provides a lighting module. As a basic embodiment of the lighting module of the present utility model, it includes a light source, a reflecting element, a first lens, and a light source mounting plane. The light beam emitted by the light source is adapted to be converged by the reflecting element and then projected through the first lens to form a designed light pattern. The light source is mounted on the light source mounting plane, and the light source mounting plane forms an inclined angle with the optical axis of the first lens, so that the direct light of the light source does not shoot towards the first lens along the optical axis direction of the first lens, so that the direct light of the light source does not fall into the dark area of the designed light pattern. The above designed light pattern can be a low beam light pattern, a high beam light pattern, and other light patterns, and there is no limitation thereto.
[0051] In the lighting module of the prior art, the mounting plane where the LED light source is located is arranged parallel to the optical axis of the lens. Therefore, the stray light of the LED light source biased towards the Y-axis will shoot directly towards the lens parallel or nearly parallel to the optical axis of the lens, and the lens projects it directly on the dark area of the light pattern without changing or hardly changing the light-emitting direction of the stray light, thereby affecting the forming quality of the light pattern.
[0052] Through the above basic implementation manner, the present utility model inclines the light source installation plane to form an inclined angle with the optical axis of the first lens, effectively preventing the direct light of the light source from irradiating the first lens along the optical axis direction of the first lens, that is, the stray light biased towards the Y-axis direction (the direction parallel to the light source installation plane) generated by the direct light of the light source will not irradiate the first lens along the optical axis direction of the first lens either. Therefore, it can ensure that the direct light of the light source does not fall into the dark area of the low beam light pattern, effectively eliminating or weakening the influence of the stray light generated by the direct light of the light source on the light pattern, and ensuring the light pattern forming quality. In addition, the lighting module of the present utility model solves the problem of the influence of stray light on the light pattern forming quality in the prior art by inclining the light source installation plane, without the need to set an additional light shielding structure, simplifying the structure, reducing the number of parts, and lowering the production cost.
[0053] For the convenience of understanding and explanation, the following will be described in conjunction with the high and low beam integrated module provided in the second aspect of the present utility model, wherein the high and low beam integrated module includes a low beam module 2 and a high beam module 3, and at least one of the low beam module 2 and the high beam module 3 is the lighting module provided in the first aspect of the present utility model.
[0054] See Figures 5 - 18 , as a specific embodiment of the high and low beam integrated module of the present utility model, the low beam module 2 includes a low beam light source 201, a low beam reflecting element 202, a first low beam lens, and a low beam installation plane 401. The first light beam emitted by the low beam light source 201 is adapted to be converged by the low beam reflecting element 202 and then projected by the first low beam lens to form a low beam light pattern. The low beam light source 201 is installed on the low beam installation plane 401. The low beam installation plane 401 forms a first angle with the optical axis C of the first low beam lens, so that the direct light of the low beam light source 201 does not irradiate the first low beam lens along the optical axis C direction of the first low beam lens, so that the direct light of the low beam light source does not fall into the dark area of the low beam light pattern. The above low beam module 2 is the lighting module provided in the first aspect of the present utility model. The low beam light source 201, the low beam reflecting element 202, the first low beam lens, and the low beam installation plane 401 respectively correspond to the light source, the reflecting element, the first lens, and the light source installation plane of the lighting module provided in the first aspect of the present utility model, so that the direct light of the low beam light source 201 does not fall into the dark area of the low beam light pattern, effectively eliminating or weakening the influence of the stray light generated by the direct light of the light source on the light pattern, and ensuring the light pattern forming quality.
[0055] It should be noted that in addition to the low beam light pattern having a clear cut-off line between light and darkness to form a bright area and a dark area, in some cases, the high beam light pattern also needs to have a clear cut-off line between light and darkness to form a bright area and a dark area of the high beam light pattern. In some embodiments of the present invention, the high beam module 3 includes a high beam light source 301, a high beam reflecting element 302, a first high beam lens, and a high beam mounting plane 402. The second light beam emitted by the high beam light source 301 is adapted to be converged by the high beam reflecting element 302 and then projected by the first high beam lens to form a high beam light pattern. The high beam light source 301 is mounted on the high beam mounting plane 402. The high beam mounting plane 402 forms a second included angle with the optical axis of the first high beam lens, so that the direct light of the high beam light source 301 does not shoot towards the first high beam lens along the optical axis direction of the first high beam lens, so that the direct light of the high beam light source does not fall into the dark area of the high beam light pattern. The above high beam module 3 is the lighting module provided in the first aspect of the present invention. The high beam light source 301, the high beam reflecting element 302, the first high beam lens, and the high beam mounting plane 402 respectively correspond to the light source, the reflecting element, the first lens, and the light source mounting plane of the lighting module provided in the first aspect of the present invention, so that the direct light of the high beam light source 301 does not fall into the dark area of the high beam light pattern, effectively eliminating or weakening the influence of stray light generated by the direct light of the light source on the light pattern, and ensuring the forming quality of the light pattern.
[0056] See Figures 5 - 7 , in order to improve the integration of the low beam and high beam integrated module of the present invention and reduce the number of parts, the first low beam lens and the first high beam lens are integrally formed. That is, the low beam and high beam integrated module of the present invention further includes an integrally formed first lens 1, and the first lens 1 includes an outer lens low beam area 101 corresponding to the first low beam lens and an outer lens high beam area 102 corresponding to the first high beam lens.
[0057] In some embodiments of the present invention, see Figure 5 , Figure 10 and Figure 12 , the low beam and high beam integrated module of the present invention further includes a lens bracket 6 for mounting the first lens 1. The first lens 1 includes an outer lens low beam area 101 for projecting the first light beam and an outer lens high beam area 102 for projecting the second light beam. The lens bracket 6 is provided with a baffle 7 on the light incident surface side of the first lens 1. The baffle 7 is arranged corresponding to the boundary line between the outer lens low beam area 101 and the outer lens high beam area 102 to prevent the light reflected by the low beam reflecting element 202 from entering the outer lens high beam area 102, and to prevent the light reflected by the high beam reflecting element 302 from entering the outer lens low beam area 101, effectively eliminating stray light and ensuring the forming quality of the low beam light pattern and the high beam light pattern. It should be noted that the first lens 1 and the lens bracket 6 can be one part or split into two parts. Being a single part is beneficial for reducing the installation structure, reducing the number of parts, and lowering the system cost; similarly, the baffle 7 can also be one part with the lens bracket 6 or split into two parts.
[0058] It should be noted that there are two specific implementation manners for the stray light of the light source (low beam light source 201 / high beam light source 301) biased towards the Y-axis not to fall into the dark area of the designed light pattern (low beam / high beam light pattern). The first specific implementation manner is that the stray light does not enter the light incident surface of the first lens, so that it cannot be projected by the first lens to affect the dark area of the light pattern. The second specific implementation manner is that the stray light enters the light incident surface of the first lens, but since the stray light does not enter parallel to the optical axis of the first lens, therefore, the stray light can be transmitted through the first lens after changing its direction and projected onto the bright area of the light pattern, so that the brightness of the bright area of the light pattern can be improved without affecting the brightness of the dark area. Therefore, in the specific embodiment of the lighting module of the present utility model, the tilt angle is configured such that the direct light emitted by the light source and parallel to the light source mounting plane does not enter the light incident surface of the first lens, or such that the direct light emitted by the light source and parallel to the light source mounting plane falls into the bright area of the designed light pattern after being transmitted through the first lens.
[0059] Correspondingly, the first angle is configured such that the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 does not enter the light incident surface of the first lens 1, or such that the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 falls into the bright area of the low beam light pattern after being transmitted through the first lens 1; the second angle is configured such that the direct light emitted by the high beam light source 301 and parallel to the high beam mounting plane 402 does not enter the light incident surface of the first lens 1, or such that the direct light emitted by the high beam light source 301 and parallel to the high beam mounting plane 402 falls into the bright area of the high beam light pattern after being transmitted through the first lens 1. It should be noted that during actual use, due to assembly errors or other design reasons, the light-emitting point of the light source may be slightly higher than its mounting plane, resulting in direct light emitted by the light source that is not parallel to its mounting surface, and the angle between the direct light and the optical axis of the light source is greater than 90°. This direct light may be projected by the first lens 1 into the dark area of the light pattern. However, since this direct light is less, its influence on the brightness of the dark area is small, and its influence on the light pattern forming quality can be ignored. Or, the angle of the first angle or the second angle can be slightly increased so that this direct light does not fall into the dark area of the light pattern either, which is also within the scope protected by the present utility model. It should also be noted that the stray light may not only include the direct light emitted by the light source and parallel to the mounting plane. As long as it affects the light pattern forming quality, it can be considered as stray light. For example, see Figure 25, the stray light may also include direct light emitted by the light source and having an angle with the light source mounting plane. Without being reflected by the reflecting element, this direct light directly projects through the first lens 1 and is located in the dark area of the designed light pattern, thus affecting the light pattern forming quality; or, the stray light may also include reflected light that is directly projected by the light source onto the reflecting element and reflected by it. This reflected light projects through the first lens 1 and is located in the dark area of the designed light pattern, thus affecting the light pattern forming quality; after forming an inclined angle between the light source mounting plane and the optical axis of the first lens, the Figure 25 propagation paths of the two types of stray light shown are changed. As shown in Figure 26 , it can be ensured that the two types of stray light shown in Figure 25 do not enter the light incident surface of the first lens and do not affect the light pattern forming quality.
[0060] In some embodiments of the present invention, the lighting module of the present invention further includes a second lens. The second lens is disposed between the reflecting element and the first lens so that the light beam converged by the reflecting element can be transmitted through the second lens and then through the first lens to form a designed light pattern, improving the forming effect of the designed light pattern. Regarding the setting of the second lens, in order to eliminate or weaken the influence of the stray light of the light source on the light pattern forming quality, the inclined angle is configured such that the direct light emitted by the light source and parallel to the light source mounting plane does not enter the light incident surface of the second lens, or the direct light emitted by the light source and parallel to the light source mounting plane does not enter the light incident surface of the first lens after being transmitted through the second lens, or the direct light emitted by the light source and parallel to the light source mounting plane falls into the bright area of the designed light pattern after being transmitted through the second lens and the first lens in sequence.
[0061] In a specific embodiment of the integrated high and low beam module of the present utility model, corresponding to the above-mentioned second lens, the low beam module 2 further includes a second low beam lens, and the high beam module 3 further includes a second high beam lens. The second low beam lens is disposed between the low beam reflecting element 202 and the low beam area 101 of the outer lens of the first lens 1, so that the first light beam converged by the low beam reflecting element 202 can be transmitted through the second low beam lens and then projected through the low beam area 101 of the outer lens of the first lens 1 to form a low beam light pattern, and the forming effect of the low beam light pattern is improved by the second low beam lens; the second high beam lens is disposed between the high beam reflecting element 302 and the high beam area 102 of the outer lens of the first lens 1, so that the second light beam converged by the high beam reflecting element 302 can be transmitted through the second high beam lens and then projected through the high beam area 102 of the outer lens of the first lens 1 to form a high beam light pattern, and the forming effect of the high beam light pattern is improved by the second high beam lens. Regarding the setting of the second lens 5, in order to eliminate or weaken the influence of the stray light of the light source on the forming quality of the light pattern, the first included angle is configured such that the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 does not enter the incident surface of the second low beam lens, or the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 does not enter the incident surface of the first lens 1 after being transmitted through the second low beam lens, or the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 falls into the bright area of the low beam light pattern after being transmitted through the second low beam lens and the first lens 1 in sequence; the second included angle is configured such that the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 does not enter the incident surface of the second high beam lens, or the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 does not enter the incident surface of the first lens 1 after being transmitted through the second high beam lens, or the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 falls into the bright area of the high beam light pattern after being transmitted through the second high beam lens and the first lens 1 in sequence. It should be noted that between the first lens 1 and the low beam module 2 / high beam module 3, there may be more than one lens disposed. When there are multiple lenses disposed, the first included angle is configured such that the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 will not be finally projected by the first lens 1, or after being projected through multiple lenses, it will be finally projected by the first lens 1 to the bright area of the low beam light pattern; the second included angle is configured such that the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 will not be finally projected by the first lens 1, or after being projected through multiple lenses, it will be finally projected by the first lens 1 to the bright area of the high beam light pattern.
[0062] See Figures 5 - 7, in order to improve the integration of the integrated high and low beam module of the present utility model and reduce the number of components, the low beam lens II and the high beam lens II are integrally formed. That is, the integrated high and low beam module of the present utility model further includes an integrally formed second lens 5, and the second lens 5 includes a low beam inner lens 501 corresponding to the low beam lens II and a high beam inner lens 502 corresponding to the high beam lens II.
[0063] In some embodiments of the present utility model, referring to Figure 5 and Figure 10 , the integrated high and low beam module of the present utility model further includes a radiator 8, and the radiator 8 can dissipate heat from the integrated high and low beam module of the present utility model to avoid damage caused by overheating. Specifically, the radiator 8 includes a first mounting surface 801 for mounting the low beam module 2 and a second mounting surface 802 for mounting the high beam module 3. The angle between the first mounting surface 801 and the second mounting surface 802 is set corresponding to the first angle and the second angle, that is, the angle between the first mounting surface 801 and the optical axis of the first lens 1 is the same as the first angle, the angle between the second mounting surface 802 and the optical axis of the first lens 1 is the same as the second angle, and the angle between the first mounting surface 801 and the second mounting surface 802 is equal to the sum of the first angle and the second angle.
[0064] In order to improve the integration, the lighting module of the present utility model further includes a circuit board for mounting the light source, and the circuit board is mounted on the radiator 8. The surface of the circuit board where the light source is located is the light source mounting plane. Specifically, referring to Figures 5 - 8 , the low beam module 2 is formed with a low beam circuit board 203 for mounting the low beam light source 201. The low beam light source 201 is integrated on the low beam circuit board 203, and the low beam circuit board 203 is mounted on the first mounting surface 801. The surface of the low beam circuit board 203 where the low beam light source 201 is located is the low beam mounting plane 401; the high beam module 3 further includes a high beam circuit board 303 for mounting the high beam light source 301. The high beam light source 301 is integrated on the high beam circuit board 303, and the high beam circuit board 303 is mounted on the second mounting surface 802. The surface of the high beam circuit board 303 where the high beam light source 301 is located is the high beam mounting plane 402.
[0065] In some embodiments of the present utility model, referring to Figure 11 , mounting edges 503 for mounting on the radiator 8 are formed on both sides of the lens II (the second lens 5). A first anti-misalignment structure 9 is provided between the mounting edge 503 and the radiator 8. The first anti-misalignment structure 9 includes a positioning hole 901 and a positioning post 902 that cooperate with each other to ensure that when the second lens 5 is mounted on the radiator 8, the radiator 8 is located on the light incident surface side of the second lens 5.
[0066] In some embodiments of the present utility model, a second anti-misalignment structure is provided between the lens II and the reflecting element. The second anti-misalignment structure includes a positioning hole II and a positioning boss that cooperate with each other. Specifically, referring to Figures 13 - 15, a second anti-misassembly structure is provided between the low-beam reflection element 202 and the second lens 5, and / or a second anti-misassembly structure 10 is provided between the high-beam reflection element 302 and the second lens 5. The second anti-misassembly structure 10 includes a cooperating positioning hole two 1001 and a positioning boss 1002 to achieve the positioning and installation of the reflection element and the second lens 5. And preferably, the second anti-misassembly structures between different component combinations should adopt an asymmetric structure design to further avoid misassembly between different components, so that the low-beam reflection element 202 and / or the high-beam reflection element 302 are both located on the designed light-incident surface side of the second lens 5, and the low-beam emission element 202 and the high-beam reflection element 302 will not be misassembled. For example, see Figure 13 and Figure 15 two different implementation manners of the anti-misassembly structure, wherein, Figure 13 the anti-misassembly structure 10 is arranged to the left, Figure 15 the anti-misassembly structure 10 is arranged to the right, so that Figure 13 and Figure 15 the two embodiments cannot be used interchangeably. In addition, in order to improve the heat dissipation performance of the high and low beam integrated module of the present invention, a gap should be provided between the second lens 5 and the reflection element to facilitate heat dissipation.
[0067] In some embodiments of the present invention, the angle of the first included angle is greater than 0° and less than or equal to 25°, which can effectively reduce or weaken the influence of stray light generated by direct light source irradiation on the low-beam light pattern; and the closer to the optical axis of the light source, the higher its luminous intensity. In order to ensure the brightness requirement of the bright area of the low-beam light pattern, preferably, the included angle of the first included angle is greater than 0° and less than or equal to 15°, so that the optical axis of the low-beam light source 201 is inclined towards perpendicular to the optical axis of the first lens 1.
[0068] In some embodiments of the present invention, the angle of the second included angle is greater than 0° and less than or equal to 15°, which can effectively reduce or weaken the influence of stray light generated by direct light source irradiation on the high-beam light pattern; and the closer to the optical axis of the light source, the higher its luminous intensity. In order to ensure the brightness requirement of the bright area of the high-beam light pattern, preferably, the included angle of the second included angle is greater than 0° and less than or equal to 5°, so that the optical axis of the high-beam light source 201 is inclined towards 90° to the optical axis of the first lens 1. It should be noted that there may be no clear requirement for the bright-dark cut-off line of the high-beam light pattern. Because, in order to ensure the brightness of the high-beam light pattern, the second included angle can also be 0°, so that the optical axis of the high-beam light source 201 is at an angle of 90° to the optical axis of the first lens 1.
[0069] In some embodiments of the present invention, see Figure 9, the first included angle is a, the linear distance from the optical center point of the low-beam light source 201 to the end of the low-beam mounting plane 401 close to the first lens 1 is A, the optical center point of the low-beam light source 201 is at the focal point of the reflecting surface of the low-beam reflecting element 202, and the value of A should be adjusted according to the value of a so that the light reflected by the reflecting surface of the low-beam reflecting element 202 from the low-beam light source 201 is not blocked by the low-beam mounting plane 401. The focal length of the reflecting surface of the low-beam reflecting element 202 is a fixed value, and the optical center point of the low-beam light source 201 is located at its focal point. The low-beam light source 201 can rotate around the optical center point within a certain angle range to adjust the size of a, and further adjust the low-beam light pattern. Among them, the larger the value of a, the larger the maximum value of A; the second included angle is b, the linear distance from the optical center point of the high-beam light source 301 to the end of the high-beam mounting plane 402 close to the first lens 1 is B, the optical center point of the high-beam light source 301 is at the focal point of the reflecting surface of the high-beam reflecting element 302, and the value of B should be adjusted according to the value of b so that the light reflected by the reflecting surface of the high-beam reflecting element 302 from the high-beam light source 301 is not blocked by the high-beam mounting plane 402. The focal length of the reflecting surface of the high-beam reflecting element 302 is a fixed value, and the optical center point of the high-beam light source 301 is located at its focal point. The high-beam light source 301 can rotate around the optical center point within a certain angle range to adjust the size of b, and further adjust the low-beam light pattern. Among them, the larger the value of b, the larger the maximum value of B; while weakening or eliminating the influence of stray light on the light pattern forming quality, avoiding the interference of the low-beam mounting plane 401 / high-beam mounting plane 402 on the light pattern formation, and ensuring the light pattern brightness. It should be noted that the low-beam and high-beam mounting planes are mainly the mounting surfaces of the circuit board. In order to meet the required distance for production and processing, in the preferred case, the above A or B is greater than 2 mm.
[0070] In some embodiments of the present invention, the reflecting element is a reflecting mirror, and the reflecting mirror is provided with a reflecting boundary corresponding to the light and dark cut-off line of the designed light pattern, and the reflecting boundary is arranged at or near the focal point of the lens for projecting the light beam converged by the reflecting element. Specifically, referring to Figure 5 and Figure 6 , the low-beam reflecting element 202 is a reflecting mirror, and the reflecting mirror is provided with a reflecting boundary 202-1 corresponding to the shape of the light and dark cut-off line of the low-beam light pattern. The reflecting boundary 202-1 is arranged at or near the focal point of the lens for transmitting the first light beam converged by the low-beam reflecting element 202, that is, corresponding to the specific embodiments with and without the second lens 5 set above. The reflecting boundary 202-1 is arranged at or near the focal point of the second lens 5 or the first lens 1, so that the light reflected by the reflecting mirror forms a preliminary illumination light pattern, and finally projects through the first lens 1 to form a low-beam light pattern with a light and dark cut-off line.
[0071] Further, the reflective boundary is located at one end of the reflector where the light source is located, and the inclination angle is configured such that the light source mounting plane does not block the light beam emitted by the light source from the reflecting surface of the reflector above the reflective boundary. Specifically, in some embodiments of the present invention, the reflective boundary 202-1 is located at one end of the low-beam reflecting element 202 close to the low-beam light source 201, and the first angle is configured such that the low-beam mounting plane 401 does not block the first light beam reflected by the reflecting surface of the low-beam reflecting element 202 above the reflective boundary 202-1, so as to avoid the low-beam mounting plane 401 blocking the preliminary illumination light pattern formed by the reflection of the reflector.
[0072] In some embodiments of the present invention, referring to Figures 16 - 18 , the high-beam reflecting element 302 includes a plurality of reflectors 302-1 and light-shielding portions 302-2 connected in sequence along the left-right direction. The reflecting surface of the reflector 302-1 can be a plane or a curved surface. Preferably, the reflecting surface of the reflector 302-1 is in a parabolic shape or an ellipsoidal shape; the light-shielding portion 302-2 can separate the reflection cavities corresponding to the respective reflectors 302-1 from each other, so as to avoid the mutual influence of stray light formed by the intersection of the light rays reflected by the adjacent reflectors 302-1.
[0073] Further, referring to Figure 17 , the light-shielding portion 302-2 includes a partition 302-2a connected to the reflector 302-1 and a retaining wall 302-2b provided on the partition 302-2a. The retaining wall 302-2b is located at the junction of two adjacent reflectors 302-1. The partition 302-2a is connected to one side of the reflector 302-1 along its light-emitting direction. The number of retaining walls 302-2b matches the number of reflectors 302-1, generally one less than the number of reflectors 302-1. The size (including height and width) of the retaining wall 302-2b can be designed accordingly according to the size of the high-beam reflecting element 302, so as to block the stray light between the reflection cavities of the plurality of reflectors 302-1. For example, the height of the retaining wall 18 can be 10-35 mm, and the width can be 0.8-2 mm.
[0074] It should be noted that, referring to Figure 19 and Figure 20 , the above high-beam reflecting element 302 can also adopt a reflector with a complete reflecting surface or a reflector formed by splicing two reflecting surfaces, without setting the light-shielding portion 302-2, so as to directly reflect and form a preliminary illumination light pattern.
[0075] It should also be noted that the specific implementation manners of projecting the preliminary illumination light pattern formed by the reflection of the high-beam reflecting element 302 into the high-beam light pattern are diverse. For example, referring to Figures 20 to 22, the initially formed illumination light pattern is directly projected through the outer lens high beam area 102 of the first lens 1 to form a high beam light pattern; or, see Figures 5 - 7 , one or more lenses are arranged between the first lens 1 and the high beam reflecting element 302. The initially formed illumination light pattern is projected through one or more lenses and then projected through the outer lens high beam area 102 of the first lens 1 to form a high beam light pattern.
[0076] In some embodiments of the high and low beam integrated module of the present invention, when the low beam module 2 is the illumination module provided in the first aspect of the present invention, the specific structure of the high beam module 3 is not limited, and it may not be the illumination module provided in the body aspect of the present invention. For example, see Figure 22 , the high beam module 3 includes a high beam light source 301, a condenser 10, and a first high beam lens (outer lens high beam area 102). The high beam light source 301 can be directly converged by the condenser 10 and directly emitted or projected through one or more lenses and then emitted to the outer lens high beam area 102 of the first lens 1 to form a high beam light pattern.
[0077] In a preferred embodiment of the present invention, see Figure 21 and Figure 22 , the outer lens high beam area 102 (first high beam lens) of the first lens 1 can be selected as a thick-wall lens to improve the overall brightness of the high beam light pattern.
[0078] As a relatively preferred specific embodiment of the present invention, a high and low beam integrated module is provided, such as Figures 5 - 10As shown, the low beam light source 201 is integrated on the low beam circuit board 203 and installed on the first mounting surface 801 of the radiator 8. The high beam light source 301 is integrated on the high beam circuit board 303 and installed on the second mounting surface 802 of the radiator 8. The first mounting surface 801 and the second mounting surface 802 are arranged vertically. The first lens 1 includes an outer lens low beam area 101 and an outer lens high beam area 102. The second lens 5 includes a low beam inner lens 501 and a high beam inner lens 502. The first light beam emitted by the low beam light source 201 is projected through the low beam reflection element 202, the low beam inner lens 501 and the outer lens low beam area 101 in sequence to form a low beam light pattern. The second light beam emitted by the high beam light source 301 is projected through the high beam reflection element 302, the high beam inner lens 502 and the outer lens high beam area 102 in sequence to form a high beam light pattern. Among them, the surface of the low beam circuit board 203 where the low beam light source 201 is located is the low beam mounting plane 401, which forms a first angle a with the optical axis direction of the first lens 1. The first angle a is configured such that the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 does not enter the light incident surface of the low beam inner lens 501, or the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 does not enter the light incident surface of the first lens 1 after passing through the low beam inner lens 501, or the direct light beam emitted by the low beam light source 201 parallel to the low beam mounting plane 401 falls into the bright area of the low beam light pattern after passing through the low beam inner lens 501 and the first lens 1 in sequence. a is greater than 0° and less than or equal to 25°. Preferably, a is greater than 0° and less than or equal to 15°. The surface of the high beam circuit board 303 where the high beam light source 301 is located is the high beam mounting plane 402, which forms a second angle b with the optical axis direction of the first lens 1. The second angle b is configured such that the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 does not enter the light incident surface of the high beam inner lens 502, or the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 does not enter the light incident surface of the first lens 1 after passing through the high beam inner lens 502, or the direct light beam emitted by the high beam light source 301 parallel to the high beam mounting plane 402 falls into the bright area of the high beam light pattern after passing through the high beam inner lens 502 and the first lens 1 in sequence. b is greater than or equal to 0° and less than or equal to 15°. Preferably, b is greater than or equal to 0° and less than or equal to 5°.
[0079] The high and low beam integrated module provided by the above preferred embodiment is beneficial for the stray light of the low beam light source 201 / high beam light source 301 biased towards the Y-axis not to fall into the dark area of the low beam light pattern and the high beam light pattern, so as to effectively eliminate and weaken the influence of the stray light generated by the direct light of the light source on the light pattern, ensure the light pattern forming quality, and the high and low beam integrated module provided by the present utility model only changes the installation angles of the low beam circuit board 203 and the high beam circuit board 303, and then changes the setting angles of the low beam installation plane 401 and the high beam installation plane 402, so as to solve the problem of light pattern forming quality caused by stray light, without setting shielding elements on the circuit board or setting additional light shielding structures in the high and low beam integrated module, which simplifies the structure, reduces the number of parts, and reduces the production cost.
[0080] In order to further show the beneficial effects of the high and low beam integrated module provided by the present utility model, the low beam light patterns formed by Example 1, Example 2 and the comparative example will be compared below.
[0081] Example 1: Select the above relatively preferred specific embodiment, wherein the first included angle a is 15°, and the formed low beam light pattern is as Figure 3 shown;
[0082] Example 2: Except that the first included angle a is set to 25°, and the other features are the same as those in Example 1, the formed low beam light pattern is as Figure 24 shown;
[0083] Example 3: Except that the first included angle a is set to 10°, and the other features are the same as those in Example 1, the formed low beam light pattern is as Figure 23 shown.
[0084] Comparative example: Except that the first included angle a is set to 0°, and the other features are the same as those in Example 1, the formed low beam light pattern is as Figure 4 shown.
[0085] Through the comparison of the low beam light patterns, it can be clearly seen that the stray light patterns above the bright and dark cut-off lines of the low beam light patterns formed by Example 1, Example 2 and Example 3 are significantly smaller than those of the comparative example. Among them, there is almost no stray light pattern above the bright and dark cut-off lines of the low beam light patterns formed by Example 1 and Example 2, and the stray light pattern above the bright and dark cut-off lines of the low beam light pattern formed by Example 3 is smaller and has less influence on the low beam light pattern. Through the above technical solutions of the lighting module of the present utility model, the influence of the stray light generated by the direct light of the light source on the light pattern can be effectively eliminated or weakened, and the light pattern forming quality can be ensured.
