Optical system, vehicle lamp and vehicle

Abstract

This invention provides an optical system comprising a light source, a reflector bowl, a housing, and an inner lens. The light source is installed within the hollow cavity formed by the reflector bowl and the housing, ensuring the light source is positioned appropriately so that its emitted light can be effectively collected by the first textured surface of the reflector bowl. The first textured surface of the reflector bowl consists of a matrix of multiple protrusions. Light from the light source strikes the reflective surface of these protrusions and is reflected at a predetermined angle onto the second textured surface of the inner lens. Reflection and refraction occur on the inner surface of the second textured surface, allowing the light to enter the inner lens and ultimately exit from the outer third textured surface. Because the second and third textured surfaces also have a diamond-patterned structure, the light undergoes further scattering and reflection upon exiting, resulting in a brilliant and sparkling illumination effect, improving light utilization efficiency and visual aesthetics. This invention also provides a vehicle headlight and a vehicle.

Description

Technical Field

[0001] This utility model belongs to the field of vehicle lighting technology, and specifically relates to an optical system, vehicle lighting, and vehicle. Background Technology

[0002] Throughout the development of automotive lighting, the pursuit of superior lighting effects has always been a core objective for major automakers. Starting with the early simple A-lights (low beam headlights), and with the gradual evolution of technology, they developed into AB-lights (combining low and high beams), and finally to the now widely popular continuous taillights. Automotive designers have continuously explored and strived to create more distinctive and attractive headlight designs to showcase the unique charm of their respective automotive brands and meet consumers' demands for personalized and high-quality automotive appearance.

[0003] In terms of lighting effects, automotive lighting technology has evolved from simple light bulbs to the widely used LED lights. Simultaneously, various optical structures and designs, such as reflectors, thick-walled components, and light guides, have emerged, enriching the luminous effects of automotive lights. Against the backdrop of advancements in materials science, scattering materials with diffusion effects have gained favor with OEMs and are widely used. These materials can transform LED point light sources into uniform light strips, achieving excellent optical consistency and gaining widespread recognition from major automakers and consumers, driving significant improvements in uniform lighting performance within the automotive lighting industry.

[0004] However, things often have two sides. The excessive pursuit of uniform headlight illumination has gradually exposed the problem of aesthetic fatigue. More and more headlights on the market exhibit similar lighting effects, especially the ubiquitous continuous taillights. Their uniform light emission weakens the differentiation between brands, diminishing the eye-catching appeal of previously unique car brands and failing to meet consumers' demands for personalization and innovation. In light of this, many automakers have begun to re-examine the development direction of headlight illumination effects, gradually abandoning the overly popular uniform illumination method and actively seeking headlight illumination solutions with novel characteristics such as brightness and brilliance, in order to reshape the personality and charm of car brands and further promote the development of headlight technology towards a more diversified and innovative direction.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] The core of this invention is to provide an optical system, a vehicle headlight, and a vehicle that can produce a bright lighting effect.

[0041] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] For details, please refer to Figures 1-7 The present invention provides an optical system comprising: a light source, a reflector bowl 100, a housing 300, and an internal lens 200.

[0043] The location of the light source is not shown in the figure and can be adapted to the actual situation. In one embodiment, the light source is an LED lamp; in other embodiments, the light source may be other light-emitting devices.

[0044] The reflector bowl 100 and the housing 300 are fastened together to form a hollow cavity for light propagation, and the light source is placed inside the hollow cavity.

[0045] The reflector bowl 100 has a first patterned surface 110 on the side facing the hollow cavity. The first patterned surface 110 includes a plurality of protrusions arranged in a matrix.

[0046] The housing 300 has mounting holes for embedding and installing the inner lens 200. The inner lens 200 is embedded in the mounting holes and secured by fasteners, which can be clamps, buckles, or other limiting structures. Both sides of the inner lens 200 are unobstructed, and each side is provided with a second patterned surface 210 and a third patterned surface 220. The second patterned surface 210 and the third patterned surface 220 face the hollow cavity side and the outer side of the headlight, respectively. Both the second patterned surface 210 and the third patterned surface 220 have irregular polygonal diamond patterns.

[0047] The reflective surfaces of each protrusion are angled to direct the light from the light source directly onto the second patterned surface 210 of the inner lens 200 facing the hollow cavity. The third patterned surface 220 is used to receive the light from the second patterned surface 210 and present a dazzling effect when emitted.

[0048] It should be noted that in this article, the hollow cavity formed by the reflector bowl 100 and the housing 300 is the inner side, and the direction facing the outside of the vehicle or the light emission direction of the headlight is the outer side.

[0049] This invention provides an optical system in which a light source is installed within the hollow cavity formed by a reflector bowl 100 and a housing 300, ensuring the light source is positioned appropriately so that its emitted light can be effectively collected by the first textured surface 110 of the reflector bowl 100. The first textured surface 110 of the reflector bowl 100 consists of a matrix of multiple protrusions. Light from the light source strikes the reflective surface of the matrix-arranged protrusions and is reflected at a predetermined angle onto the second textured surface 210 of the inner lens 200. Reflection and refraction occur on the second textured surface 210 inside the inner lens 200, allowing the light to enter the inner lens 200 and finally exit from the third textured surface 220 outside the inner lens 200. Since the second textured surface 210 and the third textured surface 220 also have a diamond-patterned structure, the light undergoes further scattering and reflection upon exiting, resulting in a brilliant and sparkling illumination effect. This allows the entire optical system to achieve the desired optical effect, improving light utilization efficiency and visual aesthetics.

[0050] In a specific embodiment, such as Figure 7 As shown, the cross-sections of the multiple protrusions are serrated. That is, the multiple protrusions constituting the first patterned surface 110, when viewed from the front, are as follows: Figure 2 As shown, they are arranged in an array, and viewed from the side, as... Figure 3 As shown, the pattern is serrated. Light rays from the light source that strike the first patterned surface 110 can be directly reflected onto the second patterned surface 210 and emitted from the third patterned surface 220 via the inner lens 200, without being reflected inside the hollow cavity, thus avoiding excessive stray light.

[0051] This setup allows for a "shining" lighting effect within a limited space by specially designing the pattern on the reflector bowl 100 and combining it with the random diamond fragment pattern on the inner lens 200.

[0052] In a preferred embodiment, the first patterned surface 110 and the second patterned surface 210 are disposed opposite to each other. For example... Figure 7 As shown, the projection of the second patterned surface 210 in the horizontal direction coincides with the first patterned surface 110. Of course, in order to better collect light from the light source, the area of ​​the first patterned surface 110 is larger than the area of ​​the second patterned surface 210.

[0053] To facilitate manufacturing and reduce costs, the reflector bowl 100 and the protrusion are integrally molded.

[0054] In a specific embodiment, the mounting hole is conical, and the embedding surface of the inner lens 200 that matches the mounting hole is conical, with the smaller diameter end of the cone facing outward and the larger diameter end facing inward.

[0055] Because the mounting hole adopts a conical design, the internal lens 200 fits tightly against the inner wall of the mounting hole when inserted. Furthermore, the conical mounting hole has an automatic centering function during the installation of the internal lens 200, ensuring installation stability while improving installation accuracy. In addition, the larger diameter end of the conical mounting hole faces inward, meaning that the inner port diameter of the internal lens is larger, allowing for more efficient reception of light reflected from the reflector bowl, thus improving the light collection efficiency of the entire optical system.

[0056] In a specific embodiment, the fastener is a clamp, which is fitted onto the large-diameter end of the endoscope 200 and connected to the housing 300. During installation, the clamp can make more natural contact with the endoscope 200 and the housing 300, eliminating the need for precise alignment and reducing assembly difficulty.

[0057] Of course, fasteners can also be screws, whose force in the conical mounting hole is evenly distributed across the contact surfaces of the inner lens 200 and the housing 300. This structure better transmits the fastening force to all parts of the inner lens 200, thereby enhancing the fastening strength. Even in complex operating environments, the inner lens 200 is not easily loosened.

[0058] In a specific embodiment, the reflector bowl 100 is provided with an ear plate 120 on its edge, and the housing 300 is provided with a mounting plate 310. Threaded holes for bolt connection are provided at corresponding positions on the ear plate 120 and the mounting plate 310. During assembly, the internal fitting mirror 200 is first installed on the housing 300, and then the reflector bowl 100 and the housing 300 are detachably connected by bolts.

[0059] Furthermore, this utility model also provides a vehicle lamp, including the optical system described in the above-described specific embodiments. This utility model also provides a vehicle, including the vehicle lamp described in the above-described specific embodiments.
