Description

Technical Field

[0001] This invention relates to the technical field of automotive lights, specifically to a light module and a light. Background Technology

[0002] In recent years, with the development trend of automotive intelligence and the continuous improvement of regulatory requirements, the field of automotive lighting has also made many corresponding adjustments and progress.

[0003] Existing headlight modules typically use an ellipsoidal reflector to converge light emitted from a light source positioned near the focal point of the ellipsoid to the far focal point of the same reflector. The far focal point of the ellipsoid is located at the focal point of a convex lens, thus the convex lens images the light spot formed at its focal point. However, this results in a large longitudinal dimension of the headlight module, which cannot meet the requirements for flattened headlights and reduced space occupation. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of large space occupation of existing vehicle lighting modules, and to provide a vehicle lighting module with the advantages of small space occupation and easy use.

[0005] To achieve the above objectives, the present invention provides a vehicle headlight module, including a low beam module, a high beam module, and a light-emitting lens. The low beam module and the high beam module are located on the same side of the light-emitting lens and are arranged vertically. The light emitted from the low beam module and the high beam module enters the light-emitting lens and exits from the light-emitting surface of the light-emitting lens.

[0006] The high beam module includes a high beam collimator, which is used to collimate the light beam and transmit the light towards the incident surface of the light-emitting lens;

[0007] The low beam module includes a low beam collimator for collimating light rays and transmitting them toward the light-emitting lens. The low beam collimator includes a low beam reflecting structure and a low beam bending structure arranged vertically. Light rays reflected by the low beam reflecting structure are transmitted upward or downward and are reflected again by the low beam bending structure, thereby changing the transmission direction of the light rays and making them suitable for incident on the light-emitting lens.

[0008] In some embodiments, the low beam module further includes a low beam source, a low beam reflection structure including a low beam collimating reflection surface, and a low beam bending structure including a bending structure reflection surface. The low beam collimating reflection surface and the bending structure reflection surface are arranged vertically. The light emitted from the low beam source is collimated by the low beam collimating reflection surface and then directed to the bending structure reflection surface, and after being reflected by the bending structure reflection surface, it is directed to the light-emitting lens.

[0009] In some embodiments, the near beam bending structure further includes a bending structure light-incident surface and a bending structure light-outcident surface. Light rays collimated by the near beam collimating reflector enter the near beam bending structure from the light-incident surface, are reflected by the bending structure reflector, and then exit from the bending structure light-outcident surface and are directed toward the light-outcident lens.

[0010] In some embodiments, the bent structure reflecting surface, the bent structure light-incident surface, and the bent structure light-exit surface are at least one of a plane, a curved surface, and a focusing surface.

[0011] In some embodiments, the bent structure reflective surface is a focusing surface, and the focal point of the bent structure reflective surface is at or within 10 mm of the near light source, or on or within 10 mm of the near light reflective structure.

[0012] In some embodiments, the low beam reflection structure and the low beam bending structure are integrated into one piece.

[0013] In some embodiments, the low beam cutoff line structure of the low beam module is located at the boundary of the low beam reflection structure.

[0014] In some embodiments, the light-emitting lens includes a high-beam lens and a low-beam lens, wherein the focal point of the low-beam lens is located at or within 10 mm of the virtual image of the low-beam light source, or at or within 10 mm of the virtual image of the low-beam reflection structure.

[0015] The near beam source and its virtual image are symmetrical about the reflective surface of the bent structure, and the near beam reflection structure and its virtual image are symmetrical about the reflective surface of the bent structure.

[0016] In some embodiments, the high beam module further includes a high beam source, and the high beam collimating device is a condenser disposed on one side of the high beam source. The light emitted from the high beam source is adapted to pass through the condenser and is collimated by the condenser before being directed toward the light incident surface of the light-emitting lens.

[0017] In some embodiments, the high beam module further includes a high beam light source, and the high beam collimating device includes a high beam collimating reflective surface. The light emitted from the high beam light source is collimated by the high beam collimating reflective surface and then directed toward the light-emitting lens.

[0018] In some embodiments, a region baffle is provided between the low beam module and the high beam module. The region baffle is integrally formed with the low beam collimating device and / or the high beam collimating device, and the end of the region baffle away from the low beam collimating device extends toward the light-emitting lens.

[0019] In some embodiments, the circuit board is also included, with a low beam module and a high beam module on one side and a heat dissipation structure on the other side.

[0020] A second aspect of the present invention provides a vehicle lamp, including the vehicle lamp module described above.

[0021] Through the above technical solutions, the low beam reflection structure and the low beam bending structure can achieve light path deflection while ensuring low beam output. Specifically, the light path of the original front and rear parts of the low beam module is partially deflected to the vertical direction by the setting of the low beam bending structure. At the same time, the light can be converged to the low beam bending structure by the setting of the low beam reflection structure, and finally the low beam output is achieved. The combination of the low beam reflection structure and the low beam bending structure effectively shortens the front and rear size of the headlight module and realizes the flattening of the headlight module.

[0052] Reference Figure 1 and Figure 4 This application discloses a vehicle headlight module, including a low beam module 1, a high beam module 2 and a light-emitting lens 3. The low beam module 1 and the high beam module 2 are located on the same side of the light-emitting lens 3 and are arranged vertically. The light emitted from the low beam module 1 and the high beam module 2 enters the light-emitting lens 3 and exits from the light-emitting surface of the light-emitting lens 3.

[0053] The high beam module 2 includes a high beam collimating device 6, which is used to collimate the light beam and transmit the light beam toward the light incident surface of the light exiting lens 3;

[0054] The low beam module 1 includes a low beam collimator 4 for collimating light and transmitting it toward the light-emitting lens 3. The low beam collimator 4 includes a low beam reflecting structure 41 and a low beam bending structure 42 arranged vertically. The light reflected by the low beam reflecting structure 41 is transmitted upward or downward. By setting the low beam bending structure 42 for reflecting the light reflected by the low beam reflecting structure 41 again, the light transmission direction is changed and it is suitable to be incident on the light-emitting surface of the light-emitting lens 3.

[0055] The high beam collimator 6 and the low beam collimator 4 are either separated vertically or integrally formed.

[0056] The low beam cutoff line structure of the low beam module 1 is located at the boundary of the low beam reflection structure 41.

[0057] The vehicle headlight module disclosed in this application includes a light-emitting lens 3. A low beam module 1 and a high beam module 2 are arranged vertically on one side of the light-incident surface of the light-emitting lens 3. The light emitted from the low beam module 1 and the high beam module 2 enters the light-emitting lens 3 and exits from the light-emitting surface of the light-emitting lens 3.

[0058] The high beam module 2 has multiple sets arranged in the left and right directions. Each high beam module 2 includes a high beam collimating device 6, which is used to collimate the light and transmit the light towards the light-incident surface of the light-emitting lens 3.

[0059] The low beam module 1 is also provided with multiple sets in the left and right direction. Each low beam module 1 includes a low beam collimating device 4. The low beam collimating device 4 includes a low beam reflecting structure 41 and a low beam bending structure 42 arranged vertically. While collimating the low beam light, the low beam collimating device 4, through the arrangement of the low beam bending structure 42, allows the light reflected by the low beam reflecting structure 41 to change the light path and transmit the light towards the light incident surface of the light exiting lens 3.

[0060] The high beam collimator 6 and the low beam collimator 4 can be set separately or as one piece. The one-piece high beam collimator 6 and the low beam collimator 4 can reduce the vertical spacing between the low beam module 1 and the high beam module 2, thereby reducing the size of the vehicle headlight module.

[0061] The low beam cutoff line structure of the low beam module 1 is located at the boundary of the low beam reflection structure 41.

[0062] In the transmission of low beam light, the low beam reflector structure 41 and the low beam bending structure 42 of the vehicle headlight module disclosed in this application can deflect the light path while ensuring the low beam output. Specifically, the light path of the original front and rear parts of the low beam module 1 is partially deflected to the vertical direction by the setting of the low beam bending structure 42. At the same time, the light can be converged to the low beam bending structure 42 by the setting of the low beam reflector structure 41, and finally the low beam output is achieved. The combination of the low beam reflector structure 41 and the low beam bending structure 42 effectively shortens the front and rear dimensions of the headlight module and realizes the flattening of the headlight module.

[0063] Example 1:

[0064] Reference Figure 1 and Figure 4 In this embodiment, the high beam module 2 is located above the low beam module 1 in the vertical direction.

[0065] Reference Figure 1 and Figure 4 The high beam module 2 also includes a high beam light source 7. The high beam collimating device 6 is a condenser set on the light-emitting side of the high beam light source 7. The rear end of the condenser is the light-incident surface, which faces the high beam light source 7. The front end of the condenser is the light-emitting surface, which faces the light-emitting lens 3. The light emitted from the high beam light source 7 enters the light-incident surface of the condenser and exits from the light-emitting surface of the condenser. The light emitted after being collimated by the condenser is directed to the light-incident surface of the light-emitting lens 3.

[0066] Reference Figure 1 and Figure 4 The light-emitting surface of the concentrator can be a flat surface or a curved surface. When the light-emitting surface is set to a curved surface, it can achieve the convergence or diffusion of high beam light.

[0067] Reference Figure 1 and Figure 4 The low beam module 1 also includes a low beam light source 5. The low beam reflection structure 41 is set to correspond to the low beam light source 5 so that the light emitted from the low beam light source 5 can be reflected by the low beam reflection structure 41. The low beam bending structure 42 is located above the low beam reflection structure 41 in the vertical direction. The side of the low beam reflection structure 41 facing the low beam light source 5 forms a low beam collimating reflection surface 411. The low beam bending structure 42 forms a bending structure reflection surface 421. The bending structure reflection surface 421 can be a total reflection surface. The light emitted from the low beam light source 5 is collimated by the low beam collimating reflection surface 411 and then shines on the low beam bending structure 42. After being reflected by the bending structure reflection surface 421, it shines on the light-emitting lens 3. The bent reflective surface 421 of the low beam bending structure 42 can deflect the low beam light path, redirecting the original front-to-back light path of the low beam module 1 downwards. Simultaneously, the low beam light source 5 and the low beam reflective structure 41 are positioned below the low beam bending structure 42. The low beam collimating reflective surface 411 of the low beam reflective structure 41 converges the light emitted from the low beam light source 5 and reflects it to the bent reflective surface 421 of the low beam bending structure 42, ultimately achieving the low beam function. The combined arrangement of the low beam reflective structure 41 and the low beam bending structure 42 effectively shortens the front-to-back dimensions of the headlight module, achieving a flattened headlight module.

[0068] Reference Figure 1 and Figure 4 The near-beam collimating reflector 411 is curved, and the direction of light reflection is directed toward the near-beam bending structure 42.

[0069] Reference Figure 1 and Figure 4The near-beam bending structure 42 is a transparent part with an approximately triangular cross-section. The near-beam bending structure 42 includes a bending structure light-incident surface 422, a bending structure reflective surface 421, and a bending structure light-exiting surface 423. The bending structure light-incident surface 422 is the side of the near-beam bending structure 42 facing the near-beam reflective structure 41, and the bending structure light-exiting surface 423 is the side of the near-beam bending structure 42 facing the light-exiting lens 3. The bending structure reflective surface 421 is the side of the near-beam bending structure 42 connecting the bending structure light-incident surface 422 and the bending structure light-exiting surface 423. The light emitted from the near-beam light source 5 is collimated by the near-beam collimating reflective surface 411 and then shines on the bending structure light-incident surface 422 and enters the near-beam bending structure 42. After being reflected by the bending structure reflective surface 421, it is emitted from the bending structure light-exiting surface 423 and shines on the light-exiting lens 3.

[0070] Reference Figure 1 and Figure 4 The angle between the longitudinal section of the bent reflective surface 421 and the optical axis of the light-emitting lens 3 is within the range of 45°±15°. The projection position of the near beam pattern can be adjusted by controlling the angle.

[0071] Reference Figure 1 and Figure 4 The bent light-incident surface 422 and / or the bent reflective surface 421 and / or the bent light-out surface 423 can be a plane, a curved surface, or a focusing surface.

[0072] For example, the bent structure reflective surface 421 is a focusing surface, preferably focusing light in a horizontal direction. Its focal point is set at or within 10 mm of the near light source 5, or on or within 10 mm of the near light reflective structure 41, which can better control the convergence and diffusion of near light.

[0073] For example, the light-incident surface 422 of the bent structure is a focusing surface, and its focal point is set at or within 10 mm of the near light source 5, or at or within 10 mm of the near light reflecting structure 41.

[0074] For example, the light-emitting surface 423 of the bent structure is a focusing surface, and its focal point is set at or within 10 mm of the virtual image 5' of the near light source, or at or within 10 mm of the virtual image 41' of the near light reflection structure.

[0075] It should be noted that, referring to Figure 4 The position of the virtual image is determined by the bending structure reflective surface 421 of the near beam bending structure 42. The near beam source 5 and the near beam source virtual image 5' are symmetrical about the bending structure reflective surface 421. The near beam reflection structure 41 and the near beam reflection structure virtual image 41' are also symmetrical about the bending structure reflective surface 421.

[0076] Reference Figure 2 and Figure 4 The light-emitting lens 3 includes a low beam lens 31 corresponding to the low beam module 1 and a high beam lens 32 corresponding to the high beam module 2. The low beam lens 31 and the high beam lens 32 are integrated into one piece, which makes the space required for the light-emitting lens 3 smaller.

[0077] The high beam lens 32 is located above the light-emitting lens 3. The high beam lens 32 can be a flat plate that does not converge or diffuse light, or it can be set as a convex lens or a concave lens to achieve the convergence or diffusion of high beam light.

[0078] The low beam lens 31 is located below the light-emitting lens 3. The low beam lens 31 is a convex lens, wherein the light-incident surface of the low beam lens 31 is a convex curved surface, and the focal point of the low beam lens 31 is located at or within 10 mm of the virtual image 5' of the low beam source, or at or within 10 mm of the virtual image 41' of the low beam reflection structure.

[0079] Reference Figure 3 A zone baffle 8 is provided between the low beam module 1 and the high beam module 2. The zone baffle 8 separates the low beam module 1 and the high beam module 2, preventing light crosstalk between the light emitted from the low beam module 1 and the high beam module 2, which would create stray light that affects the low beam pattern and the high beam pattern. One end of the zone baffle 8 can be integrally formed with either the low beam collimator 4 or the high beam collimator 6, or it can be integrally formed with both of them to reduce the number of parts and simplify installation. The end of the zone baffle 8 away from the low beam collimator 4 extends towards the light-emitting lens 3, and further, it is positioned close to the light-incident surface of the light-emitting lens 3 to enhance the anti-light crosstalk effect. In addition, the area baffle 8 can be made of transparent material, and the surface of the area baffle 8 can be provided with microstructures or textures. In low beam mode, part of the light from the low beam module 1 passes through the transparent area baffle 8 to reach the area of ​​the high beam module 2 and can be emitted through the high beam lens 32. Since the area baffle 8 is provided with microstructures or textures, it can diffuse this part of the light and reduce its energy. Therefore, it will not affect the low beam pattern and can also illuminate the high beam lens 32, so that the light-emitting lens 3 is fully illuminated in low beam mode, and the appearance of the light-emitting lens 3 is more beautiful.

[0080] Reference Figure 2 and Figure 4 The headlight module disclosed in this embodiment also includes a circuit board 9. A low beam module 1 and a high beam module 2 are disposed on one side of the circuit board 9, and a heat dissipation structure is disposed on the other side. Specifically, the circuit board 9 is located on the side of the low beam module 1 and the high beam module 2 that is away from the light-emitting lens 3. The low beam light source 5 and the high beam light source 7 are both disposed on the same side of the circuit board 9 and are spaced vertically on the circuit board 9, providing sufficient space to arrange a heat dissipation structure on the other side of the circuit board 9, thereby improving the heat dissipation effect.

[0081] The heat dissipation structure can be a heat sink 91. Specifically, a heat sink 91 is provided on the side of the circuit board 9 away from the low beam module 1 and the high beam module 2. The low beam module 1 and the high beam module 2 use the same heat sink 91 for heat dissipation, which further reduces the number of parts and saves space.

[0082] Through the above technical solution, the light path of the original front and rear parts of the low beam module 1 of this application is partially deflected to the vertical direction by the setting of the low beam bending structure 4. At the same time, the light can be converged to the low beam bending structure 42 by the setting of the low beam reflection structure 41, and finally the low beam output is realized. The combination of the low beam reflection structure 41 and the low beam bending structure 42 effectively shortens the front and rear dimensions of the headlight module and realizes the flattening of the headlight module. Meanwhile, the low beam light source 5 and the high beam light source 7 are set on the same side of the circuit board 9, which is conducive to the arrangement of the heat dissipation structure and improves the heat dissipation efficiency. The low beam lens 31 and the high beam lens 32 are integrally formed into the light output lens 3, and the low beam collimating device 4 can also be integrally formed with the high beam collimating device 6, which reduces the number of parts from multiple aspects, facilitates assembly, and reduces the size of the headlight module.

[0083] On the other hand, this application also discloses a vehicle light, including the aforementioned vehicle light module.

[0084] Example 2:

[0085] Reference Figure 5 and Figure 6 This embodiment discloses a vehicle headlight module based on Embodiment 1. The difference from Embodiment 1 is that the low beam bending structure 42 is a low beam reflector. The low beam reflector is inclined and located between the high beam collimator 6 and the low beam reflector structure 41 in the vertical direction. The reflective surface 421 of the bending structure is the reflective surface of the low beam reflector. The light reflected by the low beam reflector structure 41 is reflected again by the reflective surface of the low beam reflector and transmitted to the light-incident surface of the light-emitting lens 3. Through the combined arrangement of the low beam reflector and the low beam reflector structure 41, the light path of the original front and rear parts of the low beam module 1 is deflected to the vertical direction, while the low beam emission is also realized. This effectively shortens the front and rear dimensions of the vehicle headlight module and achieves the flattening of the vehicle headlight module.

[0086] The reflective surface of the low-light reflector, namely the bent structure reflective surface 421, can be a plane or a curved surface. Furthermore, it can be set as a focusing surface, which can reflect light while converging it. For example, the focusing surface can be a cylindrical surface extending in the left and right direction, which has a converging effect on light in the up and down direction.

[0087] Example 3:

[0088] Reference Figure 7 and Figure 8This embodiment discloses a vehicle headlight module based on Embodiment 1. The difference lies in that the low beam reflector structure 41 and the low beam bending structure 42 are integrated into one piece. The low beam collimating reflector surface 411 is connected to the light-incident surface 422 of the bending structure. The surface of the low beam collimating reflector surface 411 can be aluminum-plated. The light emitted from the low beam source 5 is directly incident on the bending structure reflector surface 421 by the low beam collimating reflector surface 411. After being reflected by the bending structure reflector surface 421, it is emitted from the bending structure light-emitting surface 423 and transmitted to the light-incident surface of the light-emitting lens 3. The integrated design of the low beam reflector structure 41 and the low beam bending structure 42 reduces the distance between them, making the headlight module more compact vertically and smaller in size. It also reduces the number of parts and makes assembly more convenient.

[0089] Example 4:

[0090] Reference Figures 9 to 11 This embodiment discloses a vehicle headlight module. In this embodiment, the low beam module 1 is located above the high beam module 2 in the vertical direction.

[0091] Reference Figures 9 to 11 The high beam module 2 also includes a high beam light source 7. The high beam collimating device 6 is a condenser set on the light-emitting side of the high beam light source 7. The rear end of the condenser is the light-incident surface, which faces the high beam light source 7. The front end of the condenser is the light-emitting surface, which faces the light-emitting lens 3. The light emitted from the high beam light source 7 enters the light-incident surface of the condenser and exits from the light-emitting surface of the condenser. The light emitted after being collimated by the condenser is directed to the light-incident surface of the light-emitting lens 3.

[0092] The low beam module 1 also includes a low beam light source 5. The low beam reflection structure 41 is set to correspond to the low beam light source 5 so that the light emitted from the low beam light source 5 can be reflected by the low beam reflection structure 41. The low beam bending structure 42 is located below the low beam reflection structure 41 in the vertical direction. The side of the low beam reflection structure 41 facing the low beam light source 5 forms a low beam collimating reflection surface 411. The low beam bending structure 42 forms a bending structure reflection surface 421. The bending structure reflection surface 421 can be a total reflection surface. The light emitted from the low beam light source 5 is collimated by the low beam collimating reflection surface 411 and then shines on the low beam bending structure 42. After being reflected by the bending structure reflection surface 421, it shines on the light-emitting lens 3. The bent reflective surface 421 of the low beam bending structure 42 can deflect the low beam light path, redirecting the original front-to-back light path of the low beam module 1 upwards. Simultaneously, the low beam light source 5 and the low beam reflective structure 41 are positioned above the low beam bending structure 42. The low beam collimating reflective surface 411 of the low beam reflective structure 41 converges the light emitted from the low beam light source 5 and reflects it to the bent reflective surface 421 of the low beam bending structure 42, ultimately achieving the low beam function. The combined arrangement of the low beam reflective structure 41 and the low beam bending structure 42 effectively shortens the front-to-back dimensions of the headlight module, achieving a flattened headlight module.

[0093] Meanwhile, the optical axis of the low beam lens 31 is positioned above the virtual image 5' of the low beam source. Because the optical axis of the low beam lens 31 is above the virtual image 5' of the low beam source, the low beam light rays are imaged below after passing through the low beam lens 31. Therefore, even if the high beam module 2 and the low beam module 1 are swapped, they can still achieve both high beam and low beam patterns.

[0094] Example 5:

[0095] Reference Figure 12 and Figure 13 This embodiment discloses a vehicle headlight module based on Embodiment 4. The difference from Embodiment 4 is that the low beam bending structure 42 is a low beam reflector. The low beam reflector is inclined and located between the high beam collimator 6 and the low beam reflector structure 41 in the vertical direction. The reflective surface 421 of the bending structure is the reflective surface of the low beam reflector. The light reflected by the low beam reflector structure 41 is reflected again by the reflective surface of the low beam reflector and transmitted to the light-incident surface of the light-emitting lens 3. Through the combined arrangement of the low beam reflector and the low beam reflector structure 41, the light path of the original front and rear parts of the low beam module 1 is deflected to the vertical direction, while the low beam emission is also realized, effectively shortening the front and rear dimensions of the headlight module and realizing the flattening of the headlight module.

[0096] In the vertical direction, the low beam module 1 is located above the high beam module 2, and the optical axis of the low beam lens 31 is positioned above the virtual image 5' of the low beam source. Because the optical axis of the low beam lens 31 is above the virtual image 5' of the low beam source, the low beam light rays are imaged below after passing through the low beam lens 31. Therefore, even if the high beam module 2 and the low beam module 1 are swapped vertically, they can still achieve both high beam and low beam patterns.

[0097] Example 6:

[0098] Reference Figure 14 and Figure 15 This embodiment discloses a vehicle headlight module based on Embodiment 4. The difference from Embodiment 4 is that the low beam reflector structure 41 and the low beam bending structure 42 are integrated into one piece. The low beam collimating reflector surface 411 is connected to the light-incident surface 422 of the bending structure. The surface of the low beam collimating reflector surface 411 is coated with aluminum. The light emitted from the low beam light source 5 is directly incident on the reflector surface 421 of the bending structure by the low beam collimating reflector surface 411. After being reflected by the reflector surface 421, the light is emitted from the light-out surface 423 of the bending structure and transmitted to the light-incident surface of the low beam lens 31. The integrated design of the low beam reflector structure 41 and the low beam bending structure 42 reduces the distance between them, making the headlight module more compact and smaller in size. It also reduces the number of parts and makes assembly more convenient.

[0099] Example 7:

[0100] Reference Figure 16 and Figure 17 This embodiment discloses a vehicle headlight module, which is based on Embodiment 4. The difference between Embodiment 4 and Embodiment 4 is that the high beam collimating device 6 is a reflector including a high beam collimating reflective surface 61. Each high beam collimating device 6 has multiple connected high beam collimating reflective surfaces 61. The high beam collimating reflective surface 61 is correspondingly arranged with the high beam light source 7. The light emitted from the high beam light source 7 is directed towards the high beam collimating reflective surface 61 and collimated by the high beam collimating reflective surface 61 before being directed towards the high beam lens 32.

[0101] The light-incident surface of the high beam lens 32 includes multiple sub-light-incident surfaces, which are correspondingly arranged with the high beam collimating device 6. The focal point of the high beam lens 32 is located at or within 10 mm of the high beam source 7, or on or within 10 mm of the high beam collimating reflective surface 61.

[0102] The light reflected by the high beam collimating reflector 61 is transmitted to the light-incident surface of the light-emitting lens 3. Through the high beam collimating device 6, the light path of the original front and rear parts of the high beam module 1 is deflected to the vertical direction, and the high beam is emitted, which effectively shortens the front and rear size of the headlight module and realizes the flattening of the headlight module.

[0103] Furthermore, in this embodiment, the low beam reflector structure 41 and the low beam bending structure 42 are integrated into one piece. The low beam collimating reflector surface 411 is connected to the light-incident surface 422 of the bending structure. The surface of the low beam collimating reflector surface 411 is coated with aluminum. The light emitted from the low beam light source 5 is directly incident on the bending structure reflector surface 421 by the low beam collimating reflector surface 411. After being reflected by the bending structure reflector surface 421, it is emitted from the bending structure light-out surface 423 and transmitted to the light-incident surface of the low beam lens 31. The integrated design of the low beam reflector structure 41 and the low beam bending structure 42 reduces the distance between them, making the headlight module more compact vertically and smaller in size. It also reduces the number of parts and makes assembly more convenient.

[0104] Example 8:

[0105] Reference Figures 18 to 21This embodiment discloses a vehicle headlight module based on Embodiment 7. The difference between Embodiment 7 and Embodiment 7 is that the low beam bending structure 42 is a low beam reflector. The low beam reflector is inclined and located between the high beam collimator 6 and the low beam reflector structure 41 in the vertical direction. The reflective surface 421 of the bending structure is the reflective surface of the low beam reflector. The light reflected by the low beam reflector structure 41 is reflected again by the reflective surface of the low beam reflector and transmitted to the light-incident surface of the light-emitting lens 3. Through the combined arrangement of the low beam reflector and the low beam reflector structure 41, the light path of the original front and rear parts of the low beam module 1 is deflected to the vertical direction, while the low beam emission is also realized. This effectively shortens the front and rear dimensions of the vehicle headlight module and achieves the flattening of the vehicle headlight module.

[0106] The reflective surface of the low-light reflector, namely the bent structure reflective surface 421, can be a plane or a curved surface. It can also be set as a focusing surface, which can reflect light and converge light at the same time. For example, the focusing surface can be a cylindrical surface that extends in the left and right direction, which has a converging effect on light in the up and down direction.

[0107] The high beam lens 32 can be a flat plate that does not converge or diffuse light, or it can be set as a convex lens or a concave lens to achieve the convergence or diffusion of high beam light.

[0108] Example 9:

[0109] Reference Figure 22 and Figure 23 This embodiment discloses a vehicle headlight module based on Embodiment 8. The difference between Embodiment 8 and Embodiment 8 is that, in the vertical direction, the low beam module 1 is located above the high beam module 2, and the optical axis of the low beam lens 31 is set above the virtual image 5' of the low beam source. Since the optical axis of the low beam lens 31 is above the virtual image 5' of the low beam source, the low beam light rays are imaged below after passing through the low beam lens 31. Therefore, even if the high beam module 2 and the low beam module 1 are swapped vertically, they can still achieve both high beam and low beam patterns.
