Description

Technical Field

[0001] This application belongs to the field of vehicle lighting technology, and particularly relates to an optical module, vehicle lamp, and vehicle. Background Technology

[0002] Current automotive headlight designs are becoming increasingly diverse, with the design of high and low beam modules primarily reflected in the lenses. These lenses are also being made smaller in aperture size to meet evolving design and market demands. Vertically, the aperture size has gradually decreased to 15mm-25mm, while horizontally, it has shrunk to 100mm-130mm, resulting in an appearance similar to the slender light guides of traffic lights. However, due to challenges in optical design such as low beam uniformity and cutoff lines, module solutions with narrower horizontal apertures are relatively rare. Therefore, modules with narrower horizontal apertures still have significant development potential and market demand. Utility Model Content

[0003] In view of this, this application provides an optical module, a vehicle headlight and a vehicle, which achieves a narrow opening in the left and right directions by arranging multiple optical units in a vertical direction to meet the needs of market styling.

[0004] For modules with small openings on the left and right sides, if a concentrator is used as the primary optical element, a spot of light shaped like the concentrator can be seen from the outside in when the headlight is on, affecting the appearance of the illuminated headlight. To address this, the optical module, headlight, and vehicle provided in this application use a low-beam reflector and / or a high-beam reflector, which can effectively avoid the situation where the concentrator spot is too obvious.

[0005] The technical solution of this application is as follows: An optical module includes multiple optical units arranged vertically. Each optical unit includes a light source, a primary optical element, and a lens unit. The primary optical element includes a near-beam reflector and / or a far-beam reflector. The lens unit is formed as a single piece, and the light-emitting surfaces of the lens unit are connected as a plane or curved surfaces with consistent curvature. Each lens unit includes at least one lens. The light emitted by the light source passes through the near beam reflector and the lens unit in sequence to form a near beam pattern, and / or the light emitted by the light source passes through the far beam reflector and the lens unit in sequence to form a far beam pattern.

[0006] In a preferred embodiment of the optical module, the reflecting surface of the near-beam reflector and / or the far-beam reflector is at least one of a parabola or a quasi-parabola, an ellipsoid or a quasi-ellipsoid.

[0007] In a preferred embodiment of the optical module, the light source includes a near-beam light source and a far-beam light source, and the primary optical element includes the near-beam reflector and the far-beam concentrator; The light emitted by the low beam source passes through the low beam reflector and the lens unit in sequence and is emitted to form a low beam pattern; the light emitted by the high beam source passes through the high beam concentrator and the lens unit in sequence and is emitted to form a high beam pattern.

[0008] In a preferred embodiment of the optical module, the reflector is provided with a cutoff line structure, or the optical unit further includes a light shield, which is provided with a cutoff line structure.

[0009] In a preferred embodiment of the optical module, the light source includes a near-beam light source and a far-beam light source, and the primary optical element includes the near-beam reflector and the far-beam reflector, wherein the far-beam reflector is a reflector bowl; The light emitted by the low beam source passes through the low beam reflector and the lens unit in sequence and is emitted to form a low beam pattern; the light emitted by the high beam source passes through the reflector and the lens unit in sequence and is emitted to form a high beam pattern.

[0010] In a preferred embodiment of the optical module, the light source includes a near-beam light source and a far-beam light source, and the primary optical element includes a near-beam condenser and a far-beam reflector, wherein the far-beam reflector is a reflector bowl; The light emitted by the low beam source passes through the low beam condenser and the lens unit in sequence to form a low beam pattern; the light emitted by the high beam source passes through the reflector and the lens unit in sequence to form a high beam pattern.

[0011] In a preferred embodiment of the optical module, the lens unit includes an inner lens and an outer lens.

[0012] In a preferred embodiment of the optical module, the primary optical element is a high-beam reflector, and the optical unit further includes an accompanying illumination structure.

[0013] Based on the same concept, this application also provides a vehicle light, including the optical module described in any of the above claims.

[0014] Based on the same concept, this application also provides a vehicle including the aforementioned vehicle lights.

[0015] Because this application adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: The optical module of this application includes multiple vertically arranged optical units, each of which is independent. Each optical unit includes a light source, a primary optical element, and a lens unit. The primary optical element includes a near-beam reflector and / or a far-beam reflector; that is, the primary optical element may include both a near-beam and a far-beam reflector, or only a near-beam reflector, or only a far-beam reflector. Light emitted from the light source passes sequentially through the near-beam reflector and the lens unit to form a near-beam pattern, and light emitted from the light source passes sequentially through the far-beam reflector and the lens unit to form a far-beam pattern, thereby enabling the optical module to have near-beam and / or far-beam functions. Simultaneously, the vertical arrangement of the optical units achieves a narrow opening in the left-right direction of the optical module, meeting market design requirements. The lens unit is formed as a single piece, and the light-emitting surface of the lens unit is either a plane or a curved surface with consistent curvature, resulting in a good appearance for the lens unit and, consequently, a good appearance for the optical module. Moreover, the primary optical element uses a reflector, which can effectively avoid the occurrence of excessively obvious light spots caused by the use of a condenser; in addition, the introduction of a reflector also results in relatively good dispersion of the optical module, which can ensure the uniformity and clarity of the light and provide good low beam and / or high beam illumination effects.

[0016] The vehicle lights and vehicles provided in this application have the same technical effects as the aforementioned optical modules. Attached Figure Description

[0023] like Figures 1 to 23 As shown, the first aspect of this application provides an optical module including a plurality of vertically arranged optical units A. Each optical unit A includes a light source, primary optical elements, and a lens unit 5. The lens unit 5 is formed as a single piece, and the light-emitting surfaces of the lens unit 5 are either planar or curved surfaces with consistent curvature. The lens unit 5 includes at least one lens. The primary optical elements include a low-beam reflector 1 and / or a high-beam reflector 2. Light emitted from the light source passes sequentially through the low-beam reflector 1 and the lens unit 5 to form a low-beam pattern, and / or, light emitted from the light source passes sequentially through the high-beam reflector 2 and the lens unit 5 to form a high-beam pattern.

[0024] The optical module of this application includes multiple vertically arranged optical units A, each of which is independent. Each optical unit A includes a light source, primary optical elements, and a lens unit 5. The primary optical elements include a near-beam reflector 1 and / or a far-beam reflector 2. That is, the primary optical elements may include both the near-beam reflector 1 and the far-beam reflector 2, or only the near-beam reflector 1, or only the far-beam reflector 2. The light emitted from the light source passes sequentially through the near-beam reflector 1 and the lens unit 5 to form a near-beam pattern, and the light emitted from the light source passes sequentially through the far-beam reflector 2 and the lens unit 5 to form a far-beam pattern, thus enabling the optical module to have near-beam and / or far-beam functions. Simultaneously, the vertical arrangement of the optical units A achieves a narrow opening in the left-right direction of the optical module, meeting market design requirements. The lens unit 5 is formed as a single piece, and the light-emitting surface of the lens unit 5 is either a plane or a curved surface with consistent curvature, resulting in a good appearance for the lens unit 5, and consequently, a good appearance for the optical module A. Moreover, the primary optical element uses a reflector, which can effectively avoid the occurrence of excessively obvious light spots caused by the use of a condenser; in addition, the introduction of a reflector also results in relatively good dispersion of the optical module, which can ensure the uniformity and clarity of the light and provide good low beam and / or high beam illumination effects.

[0025] Preferably, the reflecting surface of the low-beam reflector 1 and / or the high-beam reflector 2 is at least one of a parabolic or parabolic-like surface, an ellipsoid or an ellipsoid-like surface. A reflective coating with a reflectivity of not less than 85% may be provided on the reflecting surface, thereby efficiently reflecting the light emitted by the light source; the reflective coating may be an aluminum plating layer, etc.

[0026] As one specific embodiment of this application (Example 1), the optical module is an integrated high and low beam module, such as Figures 2 to 6 As shown, the light source includes a low-beam light source and a high-beam light source. The primary optical elements include a low-beam reflector 1 and a high-beam concentrator 4. The light emitted from the low-beam light source passes through the low-beam reflector 1 and the lens unit 5 in sequence and is emitted to form a low-beam light pattern. The light emitted from the high-beam light source passes through the high-beam concentrator 4 and the lens unit 5 in sequence and is emitted to form a high-beam light pattern.

[0027] The optical module comprises three vertically arranged optical units A. Each of the three optical units A includes a low-beam light source, a low-beam reflector 1, and a lens unit 5. Only two of the three optical units A include a high-beam light source and a high-beam condenser 4. That is, two optical units A can achieve both low-beam and high-beam illumination, while one optical unit A only achieves low-beam illumination. The low-beam patterns formed by the three optical units A combine to form the final low-beam pattern, and the high-beam patterns formed by the two optical units A combine to form the final high-beam pattern.

[0028] The low-beam reflector 1 has a reflective surface. Light emitted from the low-beam source is reflected by the reflective surface and enters the lens unit 5, then exits from the lens unit 5 to form a low-beam pattern. The shape of the reflective surface can be at least one of a parabola or a parabolic-like surface, an ellipsoid or a ellipsoid-like surface, or a freeform surface. The reflective surface is provided with a reflective coating with a reflectivity of not less than 85%, thereby efficiently reflecting light; preferably, the reflective coating can be an aluminum-plated layer, etc. Among them, a parabolic-like surface is a surface type whose shape and optical properties are similar to those of a parabola, and an ellipsoid-like surface is a surface type whose shape and optical properties are similar to those of an ellipsoid.

[0029] In the same optical unit A, the near beam source and the high beam source are mounted on the same circuit board 6, which is mounted on a heat sink 7. The circuit board 6 is bent, with the near beam source and the high beam source respectively located on opposite sides of the bend. The light emission direction of the near beam source is upward, and the light emission direction of the high beam source is forward (in other embodiments, the near beam source and the high beam source may be mounted on two separate circuit boards). The near beam source and the high beam source are separated by a certain distance, which can effectively improve the heat dissipation performance of the optical module. Furthermore, the circuit boards 6 used to mount the near beam source and the high beam source in multiple vertically arranged optical units A in the optical module can be the same circuit board, such as... Figure 3 As shown.

[0030] Both the low beam and high beam light sources can be LEDs. Other light source types can also be used in other embodiments, and there are no restrictions here.

[0031] The structure used to form the near-beam pattern also includes a cutoff line structure. The cutoff line structure can be set at the root of the near-beam reflector 1 near the near-beam source, or the optical unit A may also include a light-shielding plate 8, with the cutoff line structure set at the boundary of the light-shielding plate 8 near the lens unit 5.

[0032] Preferably, the low beam source is located at the focal point of the low beam reflector 1. The light emitted by the low beam source directly hits the reflective surface of the low beam reflector 1. After being reflected by the reflective surface, the light is projected out by the lens unit 5 to form a low beam pattern with a cutoff line. The focal point of the lens unit 5 is set at the cutoff line structure. The location of the low beam source at the focal point of the low beam reflector 1 includes a range of 5 mm around the focal point.

[0033] As some specific embodiments of this application (Example 2), such as Figures 7 to 13As shown, the optical module is an integrated high and low beam module. The light source includes a low beam source and a high beam source. The primary optical elements include a low beam concentrator 3 and a high beam reflector 2. The light emitted from the low beam source passes through the low beam concentrator 3 and the lens unit 5 in sequence and is emitted to form a low beam pattern. The light emitted from the high beam source passes through the high beam reflector 2 and the lens unit 5 in sequence and is emitted to form a high beam pattern.

[0034] The optical module comprises three vertically arranged optical units A. Each of the three optical units A includes a low-beam light source, a low-beam condenser 3, and a lens unit 5. Only two of the three optical units A include a high-beam light source and a high-beam reflector 2. That is, two optical units A can achieve both low-beam and high-beam illumination, while one optical unit A can only achieve low-beam illumination. The low-beam patterns formed by the three optical units A combine to form the final low-beam pattern, and the high-beam patterns formed by the two optical units A combine to form the final high-beam pattern.

[0035] The high beam reflector 2 employs a reflective bowl, with the bowl-shaped opening facing forward, i.e., towards the light emission direction of the optical module. The high beam reflector 2 has a reflective surface; light emitted from the high beam source is reflected by this surface and then enters the lens unit 5, exiting from the lens unit 5 to form the high beam pattern. The reflective surface is provided with a reflective coating with a reflectivity of not less than 85%, thereby efficiently reflecting the light emitted from the high beam source; preferably, the reflective coating can be an aluminum plating layer, etc.

[0036] In the same optical unit A, the low-beam light source and the high-beam light source are mounted on the same circuit board 6 and located on the same side of the circuit board 6, which is mounted on a heat sink 7; both the low-beam light source and the high-beam light source emit light forward (e.g., Figure 8 (As shown). Preferably, in the multiple vertically arranged optical units A, the near-beam light source and the far-beam light source are both located on the same side of the same circuit board 6.

[0037] Both the low beam and high beam light sources can be LEDs. Of course, other light source types can also be used in other embodiments, and there are no restrictions here.

[0038] The optical unit A also includes a light-shielding plate 8, with a cutoff line structure disposed on the light-shielding plate 8 near the boundary of the lens unit 5. Preferably, the lens focal point is disposed at the cutoff line structure.

[0039] Furthermore, the light emitted from the low beam source is converged by the low beam concentrator 3, then blocked by the light shield 8 before exiting through the lens unit 5, forming a low beam pattern with a cutoff line between light and dark areas. A portion of the light emitted from the high beam source passes sequentially through the high beam reflector 2 and then through the lens unit 5, forming a high beam pattern. Another portion of the light emitted from the high beam source strikes the lens unit 5 directly and exits from it, forming a connecting beam pattern that bridges the low beam and high beam patterns. In other words, the light emitted from the high beam source that is not reflected by the high beam reflector 2 strikes the lens unit 5 directly, improving the connection between the high beam and low beam patterns.

[0040] As one specific embodiment of this application (Example 3), the optical module is an integrated high and low beam module, such as Figures 15 to 18 The light source includes a low-beam light source and a high-beam light source, and the primary optical elements include a low-beam reflector 1 and a high-beam reflector 2. The light emitted from the low-beam light source passes through the low-beam reflector 1 and the lens unit 5 in sequence and is emitted to form a low-beam light pattern; the light emitted from the high-beam light source passes through the high-beam reflector 2 and the lens unit 5 in sequence and is emitted to form a high-beam light pattern.

[0041] The optical module comprises three vertically arranged optical units A. Each of the three optical units A includes a low-beam light source, a low-beam reflector 1, and a lens unit 5. Only two of the three optical units A include a high-beam light source and a high-beam reflector 2. That is, two optical units A can achieve both low-beam and high-beam illumination, while one optical unit A only achieves low-beam illumination. The low-beam patterns formed by the three optical units A combine to form the final low-beam pattern, and the high-beam patterns formed by the two optical units A combine to form the final high-beam pattern.

[0042] The low-beam reflector 1 has a reflective surface. Light emitted from the low-beam source is reflected by the reflective surface and enters the lens unit 5, then exits from the lens unit 5 to form a low-beam pattern. The shape of the reflective surface can be at least one of a parabola or a quasi-parabola, an ellipsoid or a quasi-ellipsoid. The high-beam reflector 2 uses a reflective bowl, with the bowl-shaped opening facing forward, i.e., towards the light emission direction of the optical module. The high-beam reflector 2 has a reflective surface. Light emitted from the high-beam source is reflected by the reflective surface and enters the lens unit 5, then exits from the lens unit 5 to form a high-beam pattern. Both the reflective surfaces of the low-beam and high-beam reflectors are provided with a reflective coating with a reflectivity of not less than 85%, thereby efficiently reflecting the light emitted from the low-beam and high-beam sources. Preferably, the reflective coating can be an aluminum plating layer, etc.

[0043] In the same optical unit A, the near beam source and the high beam source are mounted on the same circuit board 6, which is mounted on a heat sink 7. The circuit board 6 is bent, with the near beam source and the high beam source respectively located on opposite sides of the bend. The light emission direction of the near beam source is upward, and the light emission direction of the high beam source is forward (in other embodiments, the near beam source and the high beam source may be mounted on two separate circuit boards). The near beam source and the high beam source are separated by a certain distance, which can effectively improve the heat dissipation performance of the optical module. Furthermore, the circuit boards 6 used to mount the near beam source and the high beam source in multiple vertically arranged optical units A in the optical module can be the same circuit board, such as... Figure 18 As shown.

[0044] Both the low beam and high beam light sources can be LEDs. Of course, other light source types can also be used in other embodiments, and there are no restrictions here.

[0045] The structure used to form the near-beam pattern also includes a cutoff line structure. The cutoff line structure can be located at the root of the near-beam reflector 1; or the optical unit A may also include a light-shielding plate 8, with the cutoff line structure located on the boundary of the light-shielding plate 8 near the lens unit 5.

[0046] Preferably, the low beam source is located at the focal point of the low beam reflector 1. The light emitted by the low beam source directly strikes the reflective surface on the low beam reflector 1. After being reflected by the reflective surface, the light is projected out by the lens unit 5 to form a low beam pattern with a cutoff line. The focal point of the lens unit 5 is located at the cutoff line structure. The low beam source being located at the focal point of the low beam reflector 1 includes being located within a 5mm radius of the focal point, and the focal point of the lens unit 5 being located at the cutoff line structure includes being located within a 5mm radius of the cutoff line structure.

[0047] Furthermore, a portion of the light emitted from the high beam source passes sequentially through the high beam reflector 2 and the lens unit 5 to form the high beam pattern; another portion of the light emitted from the high beam source shines directly onto the lens unit 5 and exits from the lens unit 5 to form a connecting beam pattern, which connects the low beam pattern and the high beam pattern. That is, the light emitted from the high beam source that has not been reflected by the high beam reflector 2, after exiting the lens unit 5, forms a beam pattern that improves the connection between the high beam pattern and the low beam pattern.

[0048] In embodiments where both the high beam and low beam primary optical elements utilize reflectors, the light emission directions of the low beam and high beam sources differ. The upward emission of light from the low beam source prevents direct light from reaching the lens unit 5 and creating stray light. This embodiment combines the advantages of the low beam reflector 1—separating the low beam and high beam sources by a certain distance effectively improves the heat dissipation of the headlight module—with the advantages of the high beam reflector 2—light emitted from the high beam source that is not reflected by the high beam reflector 2, after directly reaching the lens unit 5, forms a beam pattern that improves the transition between the high beam and low beam patterns.

[0049] In the three embodiments of this application described above, optical unit A can simultaneously achieve both low beam and high beam illumination, or it can only achieve low beam illumination. However, the optical unit A of this application is not limited to these two forms and can also be designed to achieve only high beam illumination. Furthermore, the low beam or high beam pattern formed by each optical unit A of the optical module of this application can be combined to form the desired low beam or high beam pattern.

[0050] The optical module provided in this application can be a low beam module, a high beam module, or an integrated high / low beam module. In the low beam module, all optical units A only provide low beam illumination. In the high beam module, all optical units A only provide high beam illumination. In the integrated high / low beam module, some optical units A can only provide high beam illumination, some can only provide low beam illumination, or some can provide both low beam and high beam illumination. In all three embodiments described above, the integrated high / low beam module includes optical units A that provide both low and high beam illumination and optical units A that provide only low beam illumination. In some embodiments of the integrated high / low beam module not shown in the accompanying drawings, an optical unit A that provides only high beam illumination is included. This optical unit A includes a high beam light source, a high beam reflector 2, and a lens unit 5, and further includes an accompanying illumination structure and an accompanying illumination light source. By setting the accompanying illumination, even when the high beam is not working in low beam mode, the accompanying illumination structure will illuminate the lens unit 5, which will also illuminate the lens unit 5. In other words, in low beam mode, all lens units 5 are illuminated and there are no dark areas, making the optical module look more aesthetically pleasing when illuminated.

[0051] For lens unit 5 in an optical unit A, lens unit 5 can be a lens group, for example, including both outer lens 9 and inner lens 10, or it can include only one lens. In the case where lens unit 5 includes both outer lens 9 and inner lens 10, the light emitted from the light source passes through the primary optical element, inner lens 10 and outer lens 9 in sequence before exiting.

[0052] In the optical module of this application, the lens unit 5 is formed as a single piece and the light-emitting surface of the lens unit 5 is connected as a plane or a curved surface with the same curvature. Therefore, in the optical module of this application, the following situations can occur: First, all optical units A contain a lens (when they each contain only one lens, there is no distinction between inner lens 10 and outer lens 9), and the lenses in all optical units A are formed as a single piece; Second, all optical units A contain an outer lens 9 and an inner lens 10 respectively. In this case, the outer lenses 9 in all optical units A are formed as a single piece (called the outer lens single piece), and the inner lenses 10 in all optical units A are formed as a single piece (called the inner lens single piece); Third, at least one optical unit A contains an outer lens 9 and at least one optical unit contains an inner lens 10. This situation is similar to the second situation where some areas corresponding to optical units A are missing in the outer lens single piece and / or the inner lens single piece. In this case, in order to maintain the integrity and aesthetics of the appearance, a transparent part with equal wall thickness (the light guide 11 with equal wall thickness does not have a light-converging effect) can be set to complete the outer lens single piece and / or the inner lens single piece.

[0053] The following provides some feasible specific embodiments of the lens unit 5 of the optical module of this application. For example... Figure 19 In the illustrated embodiment, each of the three vertically arranged lens units 5 includes both an outer lens 9 and an inner lens 10. For example... Figure 20 In the illustrated embodiment, of the three vertically arranged lens units 5, only two lens units 5 simultaneously include an outer lens 9 and an inner lens 10, while the other lens unit 5 includes an outer lens 9 and a light guide 11 with equal wall thickness. For example... Figure 21 In the illustrated embodiment, of the three vertically arranged lens units 5, only two lens units 5 include both an outer lens 9 and an inner lens 10, while the other lens unit 5 includes only an outer lens 9. For example... Figure 22 In the illustrated embodiment, of the three vertically arranged lens units 5, only one lens unit 5 includes both an outer lens 9 and an inner lens 10, while the other two lens units 5 each include an outer lens 9 and a light guide 11 with equal wall thickness. Figure 23 In the embodiment shown, among the three vertically arranged lens units 5, only one lens unit 5 includes both an outer lens 9 and an inner lens 10, while the other two lens units 5 each include only an outer lens 9.

[0054] The second aspect of this application provides a vehicle light that includes the optical module provided in the first aspect of this application and has the same technical effects as the optical module.

[0055] The third aspect of this application provides a vehicle that includes the optical module provided in the first aspect of this application or the vehicle lamp provided in the second aspect of this application, and has the same technical effect as the optical module or the vehicle lamp.

[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
