Description

Technical Field

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

[0002] The light patterns of vehicle lights mainly include low beam and high beam patterns. During the use of vehicle lights, drivers need to change the light patterns of the lights in real time according to different road conditions and vehicle conditions to meet the requirements of safe driving. This requires the design of specific optical modules to realize different light patterns of vehicle lights, so as to simultaneously meet the requirements of light pattern illuminance, angle and uniformity.

[0003] According to relevant vehicle headlight standards, the low beam pattern has an important component called "Zone III". It is located above the cutoff line of the low beam pattern and mainly illuminates objects above the road surface, such as signs, so that drivers can obtain information such as signs.

[0004] Nowadays, people not only need excellent low beam and high beam performance, but also require high beam and high beam modules to have an exquisite appearance. For the formation of the low beam zone III beam pattern, most current solutions design the zone III structure on the lens, which affects the lens's aesthetics. Utility Model Content

[0005] The purpose of this application is to provide an optical module, a vehicle lamp, and a vehicle to solve the problem that the III-zone structure design in the prior art affects the aesthetics of the lens.

[0006] The technical solution of this application is as follows: An optical module includes a light source, a condenser, a light shield, and a lens, wherein at least one III-zone structure is provided on the light-emitting surface of the condenser; The light emitted from the light source is converged by the light concentrator. A portion of the light is transmitted from the upper side of the light shield and blocked by the light shield before being emitted by the lens and projected to form a near-light main beam with a cutoff line. Another portion of the light is refracted by the III-zone structure and transmitted from the lower side of the light shield before being emitted by the lens and projected to form a near-light III-zone beam. The light-shielding plate has a cutoff line structure at the edge near the lens, and at least one of the upper boundaries of the III zone structure is located above the cutoff line structure in the frontal viewing direction of the optical module.

[0007] In a preferred embodiment of the optical module, the concentrator includes a near-light concentrator, the near-light concentrator has a first light-emitting surface, and the III-zone structure is disposed at the lower part of the first light-emitting surface.

[0008] In a preferred embodiment of the optical module, the III-region structure has a III-region light-emitting surface, which is configured to be concave to or convex to the first light-emitting surface.

[0009] In a preferred embodiment of the optical module, a microstructure is provided on the light-emitting surface of region III.

[0010] In a preferred embodiment of the optical module, the III-zone structure is located on at least one side of the first light-emitting surface in the frontal viewing angle direction of the optical module.

[0011] In a preferred embodiment of the optical module, the III region structure is located on the left and / or right side of the first light-emitting surface.

[0012] In a preferred embodiment of the optical module, the concentrator further includes a high beam concentrator, the high beam concentrator having a second light-emitting surface, the low beam concentrator and the high beam concentrator being formed as a single unit, the lower edge of the first light-emitting surface being connected to the upper edge of the second light-emitting surface, and the III-zone structure being disposed at the junction of the first light-emitting surface and the second light-emitting surface.

[0013] In a preferred embodiment of the optical module, the light source includes a near-beam light source and a far-beam light source. The light emitted from the near-beam light source is converged by the near-beam concentrator, and a portion of the light is emitted from the first light-emitting surface. The emitted light is transmitted from the upper side of the light-shielding plate and blocked by the light-shielding plate before being emitted by the lens and projected to form the near-beam main beam pattern. Another portion of the light is refracted by the III-zone structure and transmitted from the lower side of the light-shielding plate before being emitted by the lens and projected to form the near-beam III-zone beam pattern. The light emitted from the far-beam light source is converged by the far-beam concentrator and emitted from the second light-emitting surface. The emitted light is transmitted from the lower side of the light-shielding plate before being emitted by the lens and projected to form the far-beam beam pattern.

[0014] Based on the same concept, this application also provides a vehicle light, including an optical module as described in any of the above.

[0015] Based on the same concept, this application also provides a vehicle including the aforementioned vehicle lights.

[0016] Because this application adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: The vehicle headlight module and headlight provided in this application have the III-zone structure positioned on the condenser rather than the lens, thus not affecting the aesthetics of the lens. Furthermore, for the integrated high / low beam module, in the frontal viewing angle direction of the optical module, the upper boundary of the III-zone structure is positioned above the cutoff line structure, reducing the impact on the brightness of the high beam.

[0024] like Figures 1 to 6 As shown, the first aspect of this application provides an optical module, including a light source, a condenser 1, a light shield 2, and a lens 3. At least one III-zone structure 9 is provided on the light-emitting surface of the condenser 1. After the light emitted from the light source is converged by the condenser 1, a portion of the light is transmitted from the upper side of the light shield 2 and blocked by the light shield 2 before being emitted by the lens 3 and projected to form a near-light main beam pattern. Another portion of the light is refracted by the III-zone structure 9 and transmitted from the lower side of the light shield 2 before being emitted by the lens 3 and projected to form a near-light III-zone beam pattern. A cutoff line structure 8 is provided at the edge of the light shield 2 near the lens 3. In the frontal viewing angle direction of the optical module, the upper boundary of at least one III-zone structure 9 is located above the cutoff line structure 8.

[0025] It should be noted that the frontal viewing angle of the optical module refers to the angle at which the optical module is viewed from the opposite direction of the light emission direction.

[0026] This application sets the III-zone structure 9 on the condenser 1 (instead of the lens 3), so that the setting of the III-zone structure 9 does not affect the aesthetics of the lens 3.

[0027] like Figure 1 As shown, the optical module is an integrated high and low beam module. The light source includes a low beam light source 12 and a high beam light source 13, which are respectively mounted on the circuit board 6. The lens 3 is mounted on the lens bracket 4. The light shield 2 can be connected to the heat sink 5, the circuit board 6, the condenser 1, and the lens bracket 4 via bolts 7. Of course, in other embodiments, the lens bracket 4, the light shield 2, the condenser 1, the circuit board 6, and the heat sink 5 in the optical module can be assembled in other ways, and this application does not limit this.

[0028] Concentrator 1 includes a low-beam concentrator and a high-beam concentrator. The low-beam concentrator has a first light-emitting surface 10, and the high-beam concentrator has a second light-emitting surface 11. A third-zone structure 9 is disposed at the lower part of the first light-emitting surface 10. Further, the low-beam concentrator and the high-beam concentrator are formed as a single unit, with the lower edge of the first light-emitting surface 10 connected to the upper edge of the second light-emitting surface 11, and the third-zone structure 9 disposed at the junction of the first light-emitting surface 10 and the second light-emitting surface 11.

[0029] The light emitted from the low beam source 12 is converged by the low beam concentrator. A portion of the light exits from the first light-emitting surface 10, is transmitted from the upper side of the light-shielding plate 2, and after being blocked by the light-shielding plate 2, is emitted by the lens 3 and projected to form the main low beam pattern. The other portion of the light is refracted by the III-zone structure 9, transmitted from the lower side of the light-shielding plate 2, and then emitted by the lens 3 and projected to form the low beam III-zone pattern. The light emitted from the high beam source 13 is converged by the high beam concentrator and exits from the second light-emitting surface 11. The emitted light is transmitted from the lower side of the light-shielding plate 2 and then emitted by the lens 3 and projected to form the high beam pattern.

[0030] A cutoff line structure 8 is provided at the edge of the light shield 2 near the lens 3. In the frontal viewing direction of the optical module, the upper boundary of at least one zone III structure 9 is located above the cutoff line structure 8. By placing the zone III structure 9 above the cutoff line structure 8, the portion located on the second light-emitting surface 11 of the high beam concentrator can be reduced, thereby reducing the impact of the zone III structure 9 on the brightness of the high beam.

[0031] Specifically, there are generally two situations to ensure that the upper boundary of the III zone structure 9 is above the cutoff line structure 8. One is that part of the III zone structure 9 is located above the light-shielding plate 2 (e.g., Figure 5 As shown), another type is where the entire III-zone structure 9 is located above the light-shielding plate 2 (as shown). Figure 6 (As shown).

[0032] The light rays refracted by structure 9 in zone III are transmitted through the lower side of the light-shielding plate 2 and then enter the lens 3. Specifically, as shown... Figure 4 As shown, the light rays forming the near-light III region light pattern are refracted by the III region structure 9 and transmitted obliquely downwards. They are transmitted under the light-shielding plate 2 and, after entering the lens 3, are finally projected above the light cutoff line of the near-light main light pattern.

[0033] Among them, the III-zone structure 9 has a III-zone light-emitting surface. After the light emitted from the near light source 12 is focused by the near light concentrator, a portion of the light is refracted when passing through the III-zone light-emitting surface. The transmission path of this portion of the light is changed, and it can be transmitted to the lower side of the light shield 2. Then, it is emitted after passing through the lens 3 and projected onto the area above the light cutoff line of the near light main light pattern to form the near light III-zone light pattern.

[0034] In one embodiment of this application, the light-emitting surface of region III is configured to be concave to or convex to the first light-emitting surface 10. Specifically, the configuration of the light-emitting surface of region III differs from that of the first light-emitting surface 10. It can be configured to be concave to or convex to the first light-emitting surface 10, so that the direction of refraction of the light forming the near beam region III light pattern when passing through the light-emitting surface of region III is different from the direction of refraction of the light forming the near beam main light pattern when passing through the first light-emitting surface 10. That is, the light refracted by the region III structure 9 can be transmitted from the lower side of the light shield 2, and then emitted after passing through the lens 3 and projected above the light cutoff line of the near beam main light pattern.

[0035] In one embodiment of this application, a microstructure is provided on the light-emitting surface of region III. The microstructure can be at least one of the following: tooth-like structure, stripes, texture, grid pattern, convex dots, conical pattern, and corn kernel pattern. No limitation is imposed here. The microstructure is beneficial to diffuse the light refracted by the light-emitting surface of region III, so that the final near-beam region III light shape brightness is more uniform.

[0036] In one embodiment of this application, the III-zone structure 9 is disposed at the lower part of the first light-emitting surface 10 of the near-light condenser, and is located on at least one side of the first light-emitting surface 10. Specifically, as shown... Figure 5 and Figure 6 As shown, in the frontal viewing direction of the optical module, the III-zone structure 9 is disposed at the lower part of the first light-emitting surface 10 and is located on both the left and right sides of the first light-emitting surface 10; in other embodiments, the III-zone structure 9 may also be located on the left or right side of the first light-emitting surface 10. Of course, the III-zone structure 9 may also be located in the middle of the lower part of the first light-emitting surface 10, and this application does not limit this.

[0037] In one embodiment of this application, the optical module is a low-beam module, the light source is a low-beam light source 12, and the concentrator 1 is a low-beam concentrator. The low-beam concentrator has a first light-emitting surface 10, and a III-zone structure 9 is disposed at the lower part of the first light-emitting surface 10. In the frontal viewing angle direction of the optical module, the upper boundary of at least one III-zone structure 9 is located above the cutoff line structure 8. After the light emitted from the low-beam light source 12 is converged by the low-beam concentrator, a portion of the light is refracted by the III-zone structure 9. This portion of the light is transmitted from the lower side of the light shield 2, and then emitted by the lens 3 and projected to form the low-beam III-zone light pattern.

[0038] A second aspect of this application provides a vehicle lamp that includes the optical module described in the above embodiments, and thus possesses all its beneficial effects, which will not be repeated here.

[0039] A third aspect of this application provides a vehicle including the aforementioned vehicle lights, thus possessing all its beneficial effects, which will not be elaborated further here.

[0040] 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.
