Detailed Implementation

[0019] The optical system, vehicle lighting fixture, and automobile proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims.

[0020] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0022] See Figures 1-3 This embodiment provides an optical system, including a light source 1 and a first optical element 2.

[0023] The light source 1 can be an LED, a laser light source, a filament bulb, a gas discharge lamp, etc., but this application is not limited to this.

[0024] The first optical element 2 includes a first optical surface 21. The first optical surface 21 has multiple crystal particles 22. The crystal particles 22 can have a multi-faceted three-dimensional geometric structure; the crystal particles 22 can be formed by combining several polyhedra with the same structure or several polyhedra with different structures. The surface of the crystal particles 22 has multiple optical unit surfaces 221, and the normal directions of adjacent optical unit surfaces 221 form an angle, that is, adjacent optical unit surfaces 221 within the same crystal particle 22 are not parallel to each other, thus forming an angular structure.

[0025] In this process, at least a portion of the light rays irradiating the optical unit surface 221 of the crystal particle 22 are directly reflected by the irradiated optical unit surface 221; and / or at least a portion of the light rays irradiating the optical unit surface 221 of the crystal particle 22 enter the interior of the crystal particle 22, are reflected by at least one other optical unit surface 221 of the crystal particle 22, and then exit through at least one optical unit surface 221 of the crystal particle 22.

[0026] The light illuminating the optical unit surface 221 is the light emitted from the light source 1 and / or ambient light. Under the natural illumination conditions of the light source 1 and / or ambient light, after the light shines on the different optical unit surfaces 221 of different crystal particles 22 on the first optical surface 21, the light is ultimately reflected and / or emitted in different directions. Therefore, when viewed from a fixed angle, bright spots with alternating light and dark are formed on the first optical surface 21. When the angle is changed, the bright spots with alternating light and dark on the first optical surface 21 also change, thus forming a dynamic and brilliant light emission effect.

[0027] In some embodiments, for the same crystal particle 22, when the light source 1 and / or ambient light illuminate the optical unit surface 221 of the crystal particle 22 along a first direction, at least a portion of the light is directly reflected by the illuminated optical unit surface 221; when the light source 1 and / or ambient light illuminate the optical unit surface 221 of the crystal particle 22 along a second direction different from the first direction, at least a portion of the light illuminating the optical unit surface 221 of the crystal particle 22 enters the interior of the crystal particle 22, is reflected by at least one other optical unit surface 221 of the crystal particle 22, and then exits through at least one optical unit surface 221 of the crystal particle 22. Thus, light illuminating the optical unit surface 221 of the crystal particle 22 from different directions exits through different optical paths of the crystal particle 22, thereby creating different light emission effects.

[0028] In a further variation, when light source 1 and / or ambient light illuminate the optical unit surface 221 of crystal particle 22 along a second direction different from the first direction, at least a portion of the light illuminating the optical unit surface 221 of crystal particle 22 enters the interior of crystal particle 22 and exits from at least one optical unit surface 221 of crystal particle 22 via a first optical path within crystal particle 22; when light source 1 and / or ambient light illuminate the optical unit surface 221 of crystal particle 22 along a third direction (different from the first and second directions), at least a portion of the light illuminating the optical unit surface 221 of crystal particle 22 enters the interior of crystal particle 22 and exits from at least one optical unit surface 221 of crystal particle 22 via a second optical path within crystal particle 22. The first and second optical paths are different, thus creating different light emission effects even when both light rays enter crystal particle 22. The optical unit surfaces 221 that the first and second optical paths pass through can be different, the number of optical unit surfaces 221 that they pass through can be different, and the final optical unit surfaces 221 that are emitted can also be different. Thus, more different optical path changes can be achieved to form a variety of light output effects.

[0029] In some embodiments, when the light source 1 and / or ambient light illuminate the optical unit surfaces 221 of different crystal particles 22 along a first direction, for some crystal particles 22, at least a portion of the light is directly reflected by the illuminated optical unit surface 221; for some crystal particles 22, after at least a portion of the light illuminating the optical unit surface 221 of the crystal particle 22 enters the interior of the crystal particle 22, it is reflected by at least one other optical unit surface 221 of the crystal particle 22, and then emitted by at least one optical unit surface 221 of the crystal particle 22. Thus, even if light illuminates the crystal particles 22 from the same direction, the different light emission effects of the multiple crystal particles 22 can achieve diverse light emission effects. Furthermore, in this embodiment, even if all the light enters the interior of the crystal particles 22, different optical path variations can exist for different crystal particles 22.

[0030] In some embodiments, whether it is light source 1 or ambient light, when it illuminates the optical unit surface 221 of the crystal particle 22, the optical path of any of the aforementioned embodiments can be realized, thereby achieving a brilliant light-emitting effect whether the light source 1 is lit or not. Furthermore, because the light source 1 and ambient light have different irradiation directions and light intensities, the brilliant effect differs when the light source 1 is lit and not lit, further enriching the light-emitting effect of the optical system. The specific structure and functionality of the optical system provided in this embodiment will be described in further detail below: Preferably, in one embodiment, at least a portion of the light irradiating the crystal particle 22 is emitted in different directions via at least two optical unit surfaces 221 of the crystal particle 22, such that after the light irradiates the first optical surface 21, the first optical surface 21 forms emitted light rays output in different directions. Based on the physical structure of the crystal particle 22, by controlling the direction and distribution of the light, the emitted light from at least two optical unit surfaces 221 of the same crystal particle 22 has a difference in brightness, thereby forming a brilliant light emission effect of the same crystal particle 22.

[0031] Preferably, in one embodiment, the angles formed between the normal directions of adjacent optical unit surfaces 221 in the multiple optical unit surfaces 221 of the same crystal particle 22 are different. Taking an irregular triangular pyramidal structure crystal particle 22 as an example, in a single crystal particle 22, a first optical unit surface, a second optical unit surface, and a third optical unit surface are provided on the side of the crystal particle 22 facing the direction of the light emitted from the light source 1 and / or the ambient light. A first angle is formed between the normal directions of the first optical unit surface and the second optical unit surface, a second angle is formed between the normal directions of the second optical unit surface and the third optical unit surface, and a third angle is formed between the normal directions of the third optical unit surface and the first optical unit surface. The first, second, and third angles are different from each other, breaking the geometric symmetry of the reflected and / or emitted light in the same crystal particle 22, making the light distribution direction more diversified.

[0032] Preferably, in one embodiment, at least two crystal particles 22 have optical unit surfaces 221 that form an angle between their normal directions, such that different crystal particles 22 on the first optical surface 21 have optical unit surfaces 221 with different orientations. When light shines on different crystal particles 22 on the first optical surface 21, the light is reflected and / or emitted in different directions, thereby efficiently forming a brilliant light emission effect.

[0033] Preferably, in one embodiment, after at least a portion of the light rays illuminating the optical unit surface 221 of the crystal particle 22 enters the crystal particle 22, are reflected by at least one other optical unit surface 221 of the crystal particle 22, and then exit through at least one optical unit surface 221 of the crystal particle 22, the incident surface and the exit surface of the crystal particle 22 are the same optical unit surface 221. That is, after the light rays enter the crystal particle 22 from the incident surface, at least one reflection occurs inside the crystal particle 22, and finally exits from the same incident surface; or the incident surface and the exit surface of the crystal particle 22 are different optical unit surfaces 221. That is, after the light rays enter the crystal particle 22 from the incident surface, at least one reflection occurs inside the crystal particle 22, and finally exits from an exit surface that is not the incident surface. Furthermore, after the light rays enter the crystal particle 22 from the incident surface, they can also be split by reflection inside the crystal particle 22, thereby allowing the light rays to exit from different optical unit surfaces 221 of the crystal particle 22.

[0034] Preferably, in one embodiment, the first optical element 2 is made of a transparent material, and the crystal particle 22 is integrally formed with the first optical element 2, wherein the first optical surface 21 of the first optical element 2 and at least a portion of the optical unit surface 221 of the crystal particle 22 are not surface treated or are surface treated with one or more of the following: The first optical surface 21 of the first optical element 2 and / or at least a portion of the optical unit surface 221 of the crystal particle 22 are provided with a texture, which can homogenize the light output effect. A reflective coating is applied to at least a portion of the optical unit surface 221 of the first optical element 2 and the crystal particle 22, thereby improving the reflection efficiency of the first optical surface 21 and the crystal particle 22.

[0035] Preferred options, see Figures 4-7 In one embodiment, the optical system further includes a first optical component 3, which is used to cause at least a portion of the light emitted by the light source 1 to be emitted in a first light-emitting direction and a second light-emitting direction, wherein at least a portion of the light emitted via the second light-emitting direction is projected onto the first optical surface 21 of the first optical element 2. In this embodiment, the first optical component 3 may include a first light-emitting surface 31 and a second light-emitting surface 32. A portion of the light emitted by the light source 1 is emitted via the first light-emitting surface 31 in the first light-emitting direction, and another portion of the light emitted by the light source 1 is emitted via the second light-emitting surface 32 in the second light-emitting direction onto the first optical surface 21 of the first optical element 2.

[0036] Specifically, in one embodiment, the first optical component 3 includes a first light-transmitting part 33 and a first reflective part 34. The first light-transmitting part 33 includes a solid light-guiding structure or a non-solid light-guiding structure, such as using air as the light-transmitting medium. The first light-transmitting part 33 is used to transmit light, and the first reflective part 34 is used to reflect light at a preset angle. The first light-transmitting part 33 and the first reflective part 34 respectively emit at least a portion of the light emitted by the light source 1 towards a first light-emitting direction and a second light-emitting direction. In one embodiment, see... Figure 8 Part of the light emitted from light source 1 is emitted directly in the first light-emitting direction through the first light-transmitting part 33, and part of the light emitted from light source 1 is reflected by the first reflective part 34 and emitted directly to the first optical element 2 in the second light-emitting direction; in another embodiment, see Figure 9 Part of the light emitted from the light source 1 is emitted to the first optical element 2 via the first light transmission part 33 in the second light emission direction, and part of the light emitted from the light source 1 is emitted in the first light emission direction after being reflected by the first reflection part 34.

[0037] Preferably, the first optical component 3 includes one optical element; or the first optical component 3 includes multiple optical elements, with the first light-transmitting part 33 and the first reflective part 34 located on the same optical element or different optical elements.

[0038] For details, please refer to Figures 4-6 , Figures 8-9In one embodiment, the first optical component 3 includes an optical element, wherein the integrally formed first light-transmitting part 33 and first reflective part 34 are configured as a single optical element, and the light path splitting function can be achieved solely through the first light-transmitting part 33 and the first reflective part 34; see also Figure 7 In one embodiment, the first optical component 3 includes multiple optical elements. One optical element is a structure consisting of a first light-transmitting part 33 and a first reflective part 34, and the other optical element is a second reflective part 35. The second reflective part 35 is used to reflect light along a preset angle. In this embodiment, the light-emitting surface of the light source 1 does not directly face the first light-transmitting part 33 and the first reflective part 34, but faces the second reflective part 35. The light emitted by the light source 1 is reflected by the second reflective part 35, and then the light path is adjusted and output to the first light-transmitting part 33 and the first reflective part 34, thereby making the arrangement of the light path inside the optical system more flexible and efficient.
