Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to an optical component, vehicle lighting and vehicle suitable for high beams. Background Technology

[0002] In commonly used lens modules, direct projection or reflection are typically employed to achieve functionality. Traditional solutions can meet certain illumination requirements, but to achieve higher illumination values, it may be necessary to sacrifice the illumination width. In addition, OEM customers now expect not only performance but also a regular, continuous, and even uniform light spot on the mask.

[0003] To address the aforementioned pain points, the inventors proposed an optical solution that can achieve a certain illuminance value, while also ensuring a wider illumination width, and with a better shape for the mask light spot than traditional methods. Utility Model Content

[0025] This utility model discloses an optical component, a vehicle headlight, and a vehicle suitable for high beams.

[0026] Example 1:

[0027] Reference Figure 1 and Figure 2 An optical component suitable for high beams includes a light source 1, a light collecting unit 2, and an imaging unit 3. The light collecting unit 2 can be a condenser. The light source 1 is a single-core light source 1, corresponding one-to-one with the condenser. The light emission center of the light source 1 is located at the focal point of the condenser. The condenser collects and focuses the light emitted from the light source 1 near the focal point of the optical system, presenting the desired light distribution. The imaging unit 3 includes a first imaging section 31 and a second imaging section 32. The outline of the first imaging section 31 in the vertical plane includes an arc, the center of which is located at the focal point of the optical system. In the horizontal plane, the first imaging section 31 can collimate the light emitted from the focal point.

[0028] It should be noted that the light collection unit 2 and the first imaging unit 31 can be integrally formed as a transparent thick-walled component.

[0029] Specifically, the second imaging unit 32 includes an incident light end and an exit light end. In the vertical plane, the second imaging unit 32 can image the light distribution at the focal plane of the optical system. In the horizontal plane, the outlines of the incident light end and the exit light end of the second imaging unit 32 are parallel to each other, and in the horizontal plane, the second imaging unit 32 has almost no effect on the light distribution at the focal plane.

[0030] The light source 1, the light collection unit 2, and the imaging unit 3 are grouped together, and the entire optical system can be composed of at least one of these optical groups.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that, in addition to being able to correspond one-to-one with a condenser, the light source 1 can also be a single multi-core LED corresponding to a single condenser. In this case, compared with a single single-core LED, the optical scheme has a wider illumination width in the horizontal direction.

[0033] In addition, the light collection unit 2 is not limited to a condenser; it can be any other optical unit, as long as it can collect the light emitted by the light source 1 and change its propagation direction. For example, it can be an optical unit that can concentrate most of the light near the focal point of the optical system or on the focal plane and be distributed at a certain angle in the horizontal direction.

[0034] Example 3:

[0035] Reference Figure 3 Unlike embodiments 1 and 2, the first imaging unit 31 may not be integrated with the light collecting unit 2; in this case, the first imaging unit 31 also includes an input end and an output end. In the vertical plane, the outline of the first imaging unit 3 includes two concentric circular arc segments; in the horizontal plane, the first imaging unit 3 realizes imaging of the light distribution at the focal plane of the system.

[0036] Working principle: Since the shape of the mask light spot depends on the relationship between the object distance and the image distance, when using a condenser, it is usually selected to be located near twice the focal length of the imaging part. At this time, the default object distance is equal to twice the focal length. The distance between the mask and the imaging part is the image distance. When the image distance is equal to twice the focal length, the image of the condenser can be clearly presented on the mask. At this time, the mask light spot will show the problem of the condenser being dark in the middle and uneven. Even if the image distance deviates from twice the focal length, the above problems still exist.

[0037] Since the imaging in this scheme consists of a first imaging unit 31 and a second imaging unit 32, and they control different imaging directions respectively, assuming that the condenser is located at 32 times the focal length of the first imaging unit, then when the image distance is equal to 2 times the focal length, only the image in the horizontal direction of the condenser will be presented, while the vertical direction will not be a clear image. Therefore, the light spot is better than the existing scheme, but the light spot is more blurred. Similarly, when the condenser is located at 2 times the focal length of the second imaging unit 32, the light spot is also better than the existing scheme, but the light spot is more blurred.

[0038] Furthermore, since the second imaging unit 32 has a larger focal length than the first imaging unit 31, it is very suitable for beam patterns that are wide horizontally and narrow vertically. Compared to conventional lens module solutions, because the first imaging unit 31 has a smaller focal length, it offers a wider horizontal angle for the same vertical angle. Additionally, the illuminance value can be adjusted by changing the focal length of the imaging unit and the position of the light collection unit 2 relative to the focal point of the optical system.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
