Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, and in particular to a pattern structure and a vehicle lamp capable of realizing large-angle refraction. Background Art

[0002] In traditional projects, due to the limitations of shape and space, most of the known solutions are direct or reflective, that is, after the light is emitted from the LED, it passes through a series of action devices and then emerges from the light-emitting surface to achieve a more uniform lighting effect of the car lights.

[0003] In traditional projects, especially headlights and taillights, the shape is relatively inclined, and regulations for functions such as steering and positioning also have visual angle requirements at large angles; usually, this problem is solved by adding visual angle patterns, but it is not beautiful when lit. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the technical problems in the prior art, the utility model provides a pattern structure and a car light that can achieve large-angle refraction. During the design, the light is refracted to the required angle through the refraction of a special pattern; the light can also be emitted through the combination of refraction within the system and multiple total reflections. While the light efficiency is high, the brightness and uniformity at large angles are also improved simultaneously, and the visual effect is transparent and aesthetically pleasing.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a pattern structure for realizing large-angle refraction, comprising a connecting surface and a total pattern surface, wherein the connecting surface and the total pattern surface are suitable for refracting light to a set angle.

[0006] The pattern structure of the utility model that realizes large-angle refraction is upgraded and optimized based on the traditional pattern. It utilizes the original invalid area to refract and fully reflect the light to the required angle, thereby improving the light effect while improving the large-angle uniformity and solving the problems of large-angle viewing angle.

[0007] Furthermore, the total pattern surface includes a first pattern surface and a second pattern surface, and the second pattern surface is arranged obliquely relative to the first pattern surface so that the light passing through the second pattern surface can be diffused at a large angle.

[0008] Furthermore, the angle between the second pattern surface and the connecting surface is an obtuse angle.

[0009] Furthermore, the angle between the second pattern surface and the connecting surface is an acute angle.

[0010] Furthermore, the connecting surface is arranged to be inclined relative to the overall pattern surface so that the light passing through the connecting surface can be diffused at a large angle.

[0011] Furthermore, the angle between the connecting surface and the overall pattern surface is an obtuse angle.

[0012] Furthermore, the angle between the connecting surface and the overall pattern surface is an acute angle.

[0013] Furthermore, the overall pattern surface adopts vertical stripes or corn kernels.

[0014] Furthermore, the LED light color is not restricted, and the light color of the same lighting area can be switched according to scene requirements.

[0015] Furthermore, a vehicle lamp comprises a plurality of the above-mentioned pattern structures, and light passes through the plurality of the pattern structures to be refracted to a set angle.

[0016] The beneficial effects of the utility model are:

[0017] 1. Based on the traditional pattern, it is upgraded and optimized, and the original invalid area is used to refract and fully reflect the light to the required angle, which improves the light effect and improves the uniformity at large angles, and can also solve the problems of large-angle viewing angle;

[0018] 2. The LED light color is not limited, and the light color of the same lighting area can be switched according to the scene requirements. For example, when changing lanes, the yellow light of the turn signal is lit; when braking, it is switched to red light, and when reversing, it is switched to white light. As long as it is reasonably combined with electronic design, the optical form of the utility model can be flexibly applied to a variety of scenes. BRIEF DESCRIPTION OF THE DRAWINGS
