Description
Technical Field
[0001] The utility model relates to a lighting module, in particular to a high and low beam integrated module and a vehicle lamp. Background Art
[0002] Currently, more and more car headlights are using integrated high and low beam modules. The integrated high and low beam module integrates the two functions of high beam and low beam. Compared with the existing form of separate arrangement of high beam module and low beam module, the number of parts is greatly reduced.
[0003] In the existing high and low beam integrated module, the high and low beam light sources adopt LED light sources 100, see Figure 1 The theoretical light emitting direction of the LED light source is the Z axis, which can well control the shape of the light pattern. Therefore, when arranging the LED light source, the optical axis of the LED light source is arranged corresponding to the reflective surface of the reflective element so that the light reflected by the reflective surface is projected by the lens to form a light pattern; however, see Figure 2 There is a certain difference between the actual light emitting direction of the LED light source and the theoretical light emitting direction. When the theoretical light emitting direction of the LED light source is perpendicular to the light emitting direction of the system, the stray light generated by the direct light of the LED light source is biased towards the Y axis. This stray light will be directly projected out by the lens without being reflected by the emitting element. Figure 3 and Figure 4 In contrast, the stray light will appear in the dark area directly above the light pattern, thus affecting the quality of the light pattern.
[0004] Therefore, it is necessary to design a high and low beam integrated module to overcome or alleviate the above technical problems. Utility Model Content

[0052] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific embodiments described below.
[0053] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0054] In the present utility model, unless otherwise specified, the directional words used, such as "above, down, left, right, front, and rear", generally refer to the positional relationship of the headlights during actual use. For example, when the headlights are set at the rear of a vehicle and emit light to the rear of the vehicle, the direction pointed by the front of the vehicle is the rear, and the direction pointed by the rear of the vehicle is the front, and "above", "down", "left", and "right" are positional relationships determined based on the positional relationship between "front" and "rear".
[0055] The first aspect of the present invention provides a high and low beam integrated module, as a basic embodiment of the high and low beam integrated module of the present invention, see Figure 5-Figure 18 , comprising a first lens 1, a low beam module 2, a high beam module 3 and a mounting portion 4, the low beam module 2 comprising a low beam light source 201 and a low beam reflecting element 202, the first light beam emitted by the low beam light source 201 being adapted to be converged by the low beam reflecting element 202 and then projected by the first lens 1 to form a low beam light pattern; the high beam module 3 comprising a high beam light source 301 and a high beam reflecting element 302, the second light beam emitted by the high beam light source 301 being adapted to be converged by the high beam reflecting element 302 and then projected by the first lens 1 to form a high beam light pattern; wherein the mounting portion 4 comprises a low beam mounting plane 401 for mounting the low beam light source 201 and a high beam mounting plane 402 for mounting the high beam light source 301, the low beam mounting plane 401 forming a first angle with the optical axis C of the first lens 1, so that the direct light of the low beam light source 201 does not project toward the first lens 1 along the direction of the optical axis C of the first lens 1, 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.
[0056] The mounting plane of the LED light source of the prior art high and low beam integrated module is arranged parallel to the optical axis of the lens. Therefore, the stray light of the LED light source deviating from the Y-axis will be directly emitted toward the lens in a direction parallel or nearly parallel to the optical axis of the lens. The lens directly projects the stray light into the dark area of the light pattern without changing or nearly changing the light emission direction, thereby affecting the molding quality of the light pattern.
[0057] Through the above-mentioned basic implementation method, the present invention tilts the low-beam mounting plane 401 so that it forms a first angle with the optical axis C of the first lens 1. This effectively prevents the direct light from the low-beam light source 201 from being emitted toward the first lens 1 along the direction of the optical axis C of the first lens 1. In other words, stray light generated by the direct light from the low-beam light source 201 that is biased toward the Y-axis direction (parallel to the direction of the low-beam mounting plane 401) will not be emitted toward the first lens 1 along the optical axis of the first lens 1. Therefore, the direct light from the low-beam light source 201 does not fall into the dark area of the low-beam light pattern, effectively eliminating or reducing the impact of stray light generated by the direct light source on the light pattern, thereby ensuring the quality of the light pattern. In addition, the present invention's integrated high and low beam module solves the problem of stray light affecting the quality of light pattern formation in the prior art by tilting the low-beam mounting plane 401 without the need for an additional light-shielding structure, thereby simplifying the structure, reducing the number of parts, and lowering production costs.
[0058] It should be noted that in addition to the low beam pattern having a clear low beam cutoff line to form bright and dark areas, in some cases, the high beam pattern also needs to have a clear high beam cutoff line to form bright and dark areas of the high beam pattern. In some embodiments of the present invention, the high beam mounting plane 402 forms a second angle with the optical axis of the first lens 1, so that the direct light from the high beam light source 301 is not emitted toward the first lens 1 along the optical axis of the first lens 1, so that the direct light from the high beam light source 301 does not fall into the dark area of the high beam pattern.
[0059] There are two specific implementation methods for preventing the stray light from the low beam light source 201 / high beam light source 301 that is biased toward the Y-axis from falling into the dark area of the low beam / high beam light pattern. The first specific implementation method is that the stray light does not enter the light incident surface of the first lens 1, and thus cannot be projected through the first lens 1 to affect the dark area of the light pattern. The second specific implementation method is that the stray light enters the light incident surface of the first lens 1, but because the stray light is not incident parallel to the optical axis of the first lens 1, the stray light can be changed in direction by the first lens 1 and transmitted into the bright area of the light pattern, thereby improving the brightness of the bright area of the light pattern without affecting the brightness of the dark area. Corresponding to the above two specific embodiments, the first angle is configured so 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 so 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 type after being transmitted through the first lens 1; the second angle is configured so 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 so 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 type after being transmitted through the first lens 1. It should be noted that, in actual use, due to assembly errors or other design reasons, the light point of the light source may be slightly higher than its installation plane, causing the light source to produce direct light that is not parallel to its installation surface, and the angle between the direct light and the optical axis of the light source is greater than 90°. The direct light may be projected through the first lens 1 and fall into the dark area of the light pattern. However, since the direct light is small, the impact on the brightness of the dark area is small, and the impact on the quality of the light pattern can be ignored. Alternatively, the angle of the first angle or the second angle can be slightly increased so that the direct light does not fall into the dark area of the light pattern, which is also within the scope of protection of the present invention. It should also be noted that the stray light can include not only the direct light emitted by the light source that is parallel to the installation plane, but any light that affects the quality of the light pattern can be considered as stray light, for example, see Figure 25 , stray light can also include direct light emitted by the light source and having an angle with the light source installation plane. Without being reflected by the reflective element, the direct light is directly projected through the first lens 1 and located in the dark area of the designed light pattern, thereby affecting the light pattern forming quality; or, stray light can also include reflected light emitted by the light source directly to the reflective element and reflected by it. The reflected light is projected through the first lens 1 and located in the dark area of the designed light pattern, thereby affecting the light pattern forming quality; and after the light source installation plane forms an inclined angle with the optical axis of lens 1, the Figure 25 The propagation paths of the two stray rays are shown in Figure 26 As shown, it is possible to Figure 25 The two stray light rays shown 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, see Figure 5 、 Figure 10 and Figure 12 The utility model's high and low beam integrated module also includes a lens holder 6 for mounting a first lens 1. The first lens 1 includes a low beam area 101 of an outer lens for projecting a first light beam and a high beam area 102 of an outer lens for projecting a second light beam. The lens holder 6 is provided with a baffle 7 located on one side of the light incident surface of the first lens 1. The baffle 7 is arranged corresponding to the boundary line between the low beam area 101 and the high beam area 102 of the outer lens to prevent light reflected by the low beam reflective element 202 from entering the high beam area 102 of the outer lens, and to prevent light reflected by the high beam reflective element 302 from entering the low beam area 101 of the outer lens, thereby effectively eliminating stray light and ensuring the molding quality of the low beam and high beam patterns. It should be noted that the first lens 1 and the lens holder 6 can be a single part or split into two parts. Using them together as one part helps reduce the installation structure, reduce the number of parts, and reduce system costs. Similarly, the baffle 7 can also be a single part with the lens holder 6 or split into two parts.
[0061] In some embodiments of the present invention, see Figure 5 、 Figure 6 、 Figure 7 and Figure 10The high and low beam integrated module of the present invention also includes a second lens 5, which includes a low beam inner lens 501 and a high beam inner lens 502. The low beam inner lens 501 is arranged between the low beam reflection 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 reflection element 202 can be transmitted through the low beam inner lens 501 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 low beam inner lens 501 is used to improve the shaping effect of the low beam light pattern; the high beam inner lens 502 is arranged between the high beam reflection 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 reflection element 302 can be transmitted through the high beam inner lens 502 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 high beam inner lens 502 is used to improve the shaping effect of the high beam light pattern. With respect to 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 quality of the light pattern, the first angle is configured so 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 low beam inner lens 501, or 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 after being transmitted through the low beam inner lens 501, or the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 sequentially passes through the low beam inner lens 501 and the low beam inner lens 501. After transmission through the first lens 1, the light falls into the bright area of the low beam light type; the second angle is configured so 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 high beam inner lens 502, or so 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 after transmission through the high beam inner lens 502, or so that the direct light emitted by the high beam light source 301 and parallel to the high beam mounting plane 402 passes through the high beam inner lens 502 and the first lens 1 in sequence and falls into the bright area of the high beam light type. It should be noted that there may be more than one lens between the first lens 1 and the low beam module 2 / high beam module 3. When multiple lenses are provided, the first angle is configured so that the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 will not ultimately be projected by the first lens 1, or after being projected by multiple lenses, it will ultimately be projected by the first lens 1 to the bright area of the low beam light type; the second angle is configured so that the direct light emitted by the high beam light source 301 and parallel to the high beam mounting plane 402 will not ultimately be projected by the first lens 1, or after being projected by multiple lenses, it will ultimately be projected by the first lens 1 to the bright area of the high beam light type.
[0062] In some embodiments of the present invention, the low beam inner lens 501 and the high beam inner lens 502 are integrally formed, which helps to reduce the installation structure, reduce the number of parts, and reduce the system cost.
[0063] In some embodiments of the present invention, see Figure 5 and Figure 10 The high and low beam integrated module of the present invention also includes a radiator 8, which can dissipate heat for the high and low beam integrated module of the present invention to avoid overheating damage. 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 corresponds 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] To improve integration, see Figure 5-Figure 8 The low beam module 2 is formed with a low beam circuit board 203 for installing a low beam light source 201. The low beam light source 201 is integrated on the low beam circuit board 203. The low beam circuit board 203 is installed 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 also includes a high beam circuit board 303 for installing a high beam light source 301. The high beam light source 301 is integrated on the high beam circuit board 303. The high beam circuit board 303 is installed 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 invention, see Figure 11 , mounting edges 503 for mounting on the radiator 8 are formed on both sides of the second lens 5, and a first anti-error structure 9 is provided between the mounting edge 503 and the radiator 8. The first anti-error structure 9 includes a positioning hole 901 and a positioning column 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 side of the second lens 5.
[0066] In some embodiments of the present invention, see Figure 13-15 A second error-proofing structure is provided between the low-beam reflective element 202 and the second lens 5, and / or a second error-proofing structure 10 is provided between the high-beam reflective element 302 and the second lens 5. The second error-proofing structure 10 includes a second positioning hole 1001 and a positioning boss 1002 that cooperate with each other to realize the positioning and installation of the reflective element and the second lens 5. Preferably, the second error-proofing structure between different component combinations should adopt an asymmetric structural design to further avoid misassembly between different components, so that the low-beam reflective element 202 and / or the high-beam reflective element 302 are both located on the side of the designed light incident surface of the second lens 5, and the low-beam reflective element 202 and the high-beam reflective element 302 will not be mixed. For example, see Figure 13 and Figure 15 Two different implementation methods of error-proofing structure, among which, Figure 13 The error-proofing structure 10 is arranged on the left side. Figure 15 The error-proofing structure 10 is arranged to the right, so that Figure 13 and Figure 15 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 reflective element to facilitate heat dissipation.
[0067] In some embodiments of the present invention, the angle of the first 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 from the light source on the low beam light type; and the closer to the optical axis of the light source, the higher the luminous intensity. In order to ensure the brightness requirements of the bright area of the low beam light type, preferably, the angle of the first angle is greater than 0° and less than or equal to 15°, so that the angle between the optical axis of the low beam light source 201 and the optical axis of the first lens 1 is biased towards vertical.
[0068] In some embodiments of the present invention, the second angle is greater than 0° and less than or equal to 15°, which can effectively reduce or weaken the impact of stray light generated by direct light from the light source on the high-beam pattern. Furthermore, the closer to the optical axis of the light source, the higher the luminous intensity. To ensure the brightness requirements of the bright area of the high-beam pattern, the second angle is preferably greater than 0° and less than or equal to 5°, so that the angle between the optical axis of the high-beam light source 201 and the optical axis of the first lens 1 is biased towards 90°. It should be noted that the high-beam pattern does not have a clear cutoff requirement. To ensure the brightness of the high-beam pattern, the second angle can also be 0°, so that the angle between the optical axis of the high-beam light source 201 and the optical axis of the first lens 1 is 90°.
[0069] In some embodiments of the present invention, see Figure 9, the first included angle is a, the straight-line 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 focus of the reflection surface of the low beam reflective element 202, the value of A should be adjusted according to the value of a, so that the light reflected by the low beam light source 201 through the reflection surface of the low beam reflective element 202 is not blocked by the low beam mounting plane 401, the focal length of the reflection surface of the low beam reflective element 202 is a fixed value, the optical center point of the low beam light source 201 is at its focus, the low beam light source 201 can be rotated around the optical center point within a certain angle range to adjust the size of a, and then adjust the low beam light type, wherein the larger the value of a, the larger the maximum value of A; the second included angle is b, the distance from the optical center point of the high beam light source 301 to the high beam mounting plane 40 The straight-line distance from one end of the first lens 1 is B. The optical center of the high-beam light source 301 is at the focal point of the reflective surface of the high-beam reflective element 302. The value of B should be adjusted based on the value of b so that the light reflected from the high-beam light source 301 by the reflective surface of the high-beam reflective element 302 is not blocked by the high-beam mounting plane 402. The focal length of the reflective surface of the high-beam reflective element 302 is fixed, and the optical center of the high-beam light source 301 is at its focal point. The high-beam light source 301 can be rotated within a certain angle range around the optical center to adjust the value of b, and thus the low-beam light pattern. The larger the value of b, the greater the maximum value of B. While reducing or eliminating the impact of stray light on the light pattern quality, the low-beam mounting plane 401 / high-beam mounting plane 402 is prevented from interfering with the light pattern, ensuring the brightness of the light pattern. It should be noted that the high-beam and low-beam mounting planes are primarily the mounting surfaces of circuit boards. To meet the required distances for production and processing, the above-mentioned A or B is preferably greater than 2 mm.
[0070] In some embodiments of the present invention, see Figure 5 and Figure 6 The low-beam reflective element 202 is a reflector, which is provided with a reflective boundary 202-1 corresponding to the shape of the light cut-off line of the low-beam light pattern. The reflective boundary 202-1 is set at or near the focus of the lens for transmitting the first light beam converged by the low-beam reflective element 202, that is, corresponding to the specific embodiments with and without the second lens 5, the reflective boundary 202-1 is set at or near the focus of the second lens 5 or the first lens 1, so that the light reflected by the reflector forms a preliminary lighting light pattern, and finally is projected through the first lens 1 to form a low-beam light pattern with both light cut-off lines.
[0071] In some embodiments of the present invention, the reflective boundary 202-1 is located at one end of the low beam reflective element 202 close to the low beam light source 201, and the first angle is configured so that the low beam mounting plane 401 does not block the first light beam reflected by the reflective surface of the low beam reflective element 202 located above the reflective boundary 202-1, so as to avoid the low beam mounting plane 401 blocking the preliminary lighting light pattern formed by reflection of the reflector.
[0072] In some embodiments of the present invention, see Figure 16-18 The high beam reflection element 302 includes a plurality of reflectors 302-1 and a light-isolating portion 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 parabolic or ellipsoidal; the light-isolating portion 302-2 can separate the reflection cavities corresponding to each reflector 302-1 from each other to avoid the cross-interference of stray light formed by the light reflected by adjacent emitting mirrors 302-1.
[0073] Further, see Figure 17 The light-isolating portion 302-2 includes a partition 302-2a connected to the reflector 302-1 and a retaining wall 302-2b disposed 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 the light-emitting direction thereof. The number of retaining walls 302-2b matches the number of reflectors 302-1, generally being one less than the number of reflectors 302-1. The dimensions (including height and width) of the retaining wall 302-2b can be designed accordingly based on the size of the high-beam reflective element 302 to block stray light from the reflection cavities of the multiple reflectors 302-1. For example, the height of the retaining wall 18 can be 10 to 35 mm, and the width can be 0.8 to 2 mm.
[0074] It should be noted that, see Figure 19 and Figure 20 The high beam reflective element 302 can also be a reflective mirror with a complete reflective surface, or a reflective mirror formed by splicing two reflective surfaces, without the need for the light-isolating portion 302-2, so that the preliminary illumination light pattern can be directly reflected. In addition, there are various specific implementations of projecting the preliminary illumination light pattern formed by the high beam reflective element 302 into the high beam light pattern. For example, see Figures 20 to 22 The initially formed illumination light pattern is directly projected through the outer lens far beam area 102 of the first lens 1 to form a far beam light pattern; or, see Figure 5-Figure 7 , one or more lenses are arranged between the first lens 1 and the high-beam reflective element 302, and the initially formed illumination light pattern is projected by the one or more lenses and then projected by the outer lens high-beam area 102 of the first lens 1 to form a high-beam light pattern; or, see Figure 22 , a concentrator 10 is provided, and the high beam light source 301 can be directly emitted after being focused by the concentrator 10 or projected through one or more lenses to the high beam area 102 of the outer lens of the first lens 1 to form a high beam light pattern. Preferably, see Figure 21 and Figure 22 The outer lens high beam zone 102 of the first lens 1 may use a thick-walled lens, thereby improving the overall brightness of the high beam pattern.

The first light beam emitted by the low beam light source 201 is sequentially projected through the low beam reflection element 202, the low beam inner lens 501 and the low beam area 101 of the outer lens to form a low beam light pattern. The second light beam emitted by the high beam light source 301 is sequentially projected through the high beam reflection element 302 and the high beam area 102 of the outer lens of the high beam inner lens 502 to form a high beam light pattern. The surface of the low beam light source 201 on the low beam circuit board 203 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 so that the low beam light source 201 emits a light parallel to the low beam. The direct light from the low beam mounting plane 401 does not enter the light incident surface of the low beam inner lens 501, or the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 is transmitted through the low beam inner lens 501 and does not enter the light incident surface of the first lens 1, or the direct light emitted by the low beam light source 201 and parallel to the low beam mounting plane 401 is transmitted through the low beam inner lens 501 and the first lens 1 in sequence and falls into the bright area of the low beam light type, 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, and ... A second angle b is formed in the direction of the optical axis, and the second angle b is configured so 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 high-beam inner lens 502, or so 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 after being transmitted through the high-beam inner lens 502, or so that the direct light emitted by the high-beam light source 301 and parallel to the high-beam mounting plane 402 passes through the high-beam inner lens 502 and the first lens 1 in sequence and falls into the bright area of the high-beam light pattern, b is greater than or equal to 0° and less than or equal to 15°, and preferably, b is greater than or equal to 0° and less than or equal to 5°.
[0076] The high and low beam integrated module provided by the above-mentioned preferred embodiment is beneficial to preventing the stray light of the low beam light source 201 / high beam light source 301 from being biased toward the Y-axis from falling into the dark area of the low beam light pattern and the high beam light pattern, thereby effectively eliminating the influence of the stray light generated by the direct radiation of the weakened light source on the light pattern, and ensuring the quality of the light pattern forming. The high and low beam integrated module provided by the utility model only solves the light pattern forming quality problem caused by stray light by tilting the installation angles of the low beam circuit board 203 and the high beam circuit board 303, and then changing the setting angles of the low beam mounting plane 401 and the high beam mounting plane 402. There is no need to set a shielding element on the circuit board, or to set an additional shading structure in the high and low beam integrated module, which simplifies the structure, reduces the number of parts, and reduces production costs.
[0077] In order to further demonstrate the beneficial effects of the high and low beam integrated module provided by the present invention, the low beam patterns formed by the first embodiment, the second embodiment and the comparative example are compared below.
[0078] Example 1: Select the above relatively preferred specific embodiment, wherein the first angle a is 15°, and the low beam pattern formed is as follows Figure 3 As shown;
[0079] Example 2: Except that the first angle a is set to 25 degrees, the other features are the same as those of Example 1. The low beam pattern formed is as follows: Figure 24 As shown;
[0080] Example 3: Except that the first angle a is set to 10°, the other features are the same as in Example 1. The low beam pattern formed is as follows Figure 23 As shown;
[0081] Comparative Example: Except that the first angle a is set to 0°, the other features are the same as those of Example 1. The low beam pattern formed is as follows: Figure 4 shown.
[0082] By comparing the low-beam patterns, it is clearly seen that the stray light patterns above the cutoff line in the low-beam patterns formed by Examples 1, 2, and 3 are significantly smaller than the stray light pattern in the comparative example. Specifically, the low-beam patterns formed by Examples 1 and 2 have almost no stray light patterns above the cutoff line, while the low-beam pattern formed by Example 3 has a smaller stray light pattern above the cutoff line, thus having a smaller impact on the low-beam pattern. The above-mentioned technical solution of the lighting module of the present invention can effectively eliminate or reduce the impact of stray light generated by direct light from the light source on the light pattern, ensuring the quality of the light pattern.
