Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamps, and in particular relates to a light-collecting structure and a vehicle lamp comprising the same. Background Art

[0002] Due to the changes in the aesthetic requirements of OEMs and market customers for the shape of car lights, car lights are gradually shifting towards miniaturization and diversification, which in turn leads to narrower and narrower light outlets for car lights. For optical designers, the narrower the light outlet, the lower the efficiency of the narrow light outlet for the same structure and design, which brings obstacles to meeting the requirements of optical design.

[0003] At present, in order to meet the optical design requirements of narrow light outlets, the method adopted is to use a large number of LED light sources or increase the power of the LED light sources to increase the luminous flux of the optical system. However, increasing the number of LED light sources and increasing the power will greatly increase the production cost. Therefore, solving the problem of low efficiency of narrow light outlets by increasing the number of LED light sources and the power is difficult to meet customer needs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a focusing structure and a car light containing the same, which collects light through refraction through the pattern on the outer surface of the focusing body to form a rectangular light spot, thereby improving the lighting efficiency and reducing the power consumption of the system. The light intensity distribution of the light spot is uniform and the lighting distribution performance is stable.

[0005] The utility model provides a light-collecting structure, comprising:

[0006] A light-concentrating body, wherein a light source is disposed on the light-incident side of the light-concentrating body, and a light-distributing pattern unit is disposed on the light-exiting side of the light-concentrating body, wherein the light-distributing pattern unit comprises a plurality of pattern structures, and a focus of each pattern structure forms a focal line;

[0007] The light emitted by the light source is collimated by the focusing body and then refracted to the light distribution pattern unit on the light output side, and the light is gathered to the focus for collection.

[0008] Furthermore, each pattern structure is an arc-shaped curved surface that arches from the light-incoming end side of the light-concentrating body toward the light-emitting end side of the light-concentrating body.

[0009] Furthermore, the focal lines of the multiple pattern structures are parallel to each other.

[0010] Furthermore, the focusing body is a rotating concentrator.

[0011] Furthermore, patterns are provided on the inner wall and / or outer wall of the focusing body.

[0012] Furthermore, the light color of the light source is one or more of white light, yellow light, red light, blue light and green light.

[0013] The utility model also includes a vehicle lamp, comprising the light-collecting structure as described above.

[0014] The beneficial effects of the utility model are:

[0015] The utility model is a focusing structure. After the light emitted by the light source is collimated by the focusing body, it is refracted to the light distribution pattern unit on the light output side. The light is gathered to the focus to collect light, forming a rectangular light spot, improving the light effect, reducing the system power consumption, and the rectangular light spot has uniform light intensity distribution and stable light distribution performance. The utility model has a simple structure, is easy to implement, can effectively reduce system power consumption, and save production costs.

[0016] Since the vehicle lamp of the utility model has the light-collecting structure, it also has the advantages of the light-collecting structure.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 to Figure 2 As shown, the utility model provides a light focusing structure, comprising:

[0025] A light-concentrating body 1, a light source is provided on the light-incident side of the light-concentrating body 1, a light-distributing pattern unit 2 is provided on the light-exiting side of the light-concentrating body 1, the light-distributing pattern unit 2 includes a plurality of pattern structures, and the focus of each pattern structure forms a focal line;

[0026] The light emitted by the light source is collimated by the focusing body 1 and then refracted to the light distribution pattern unit 2 on the light output side. The light is gathered to the focus to form a rectangular light spot.

[0027] Each pattern structure is an arc-shaped curved surface that arches from the light-entering end side of the focusing body 1 toward the light-emitting end side of the focusing body 1. In other words, the light distribution pattern unit of the utility model is a curve with a focus stretched along the length direction to form multiple arc-shaped curved surfaces. In actual use, the curvature of the curved surface can be adjusted according to actual needs to adjust the focal length, thereby controlling the range of the rectangular light spot. For example: rear fog light function: a rectangular light spot with a range of 10 degrees left and right and 5 degrees up and down.

[0028] In order to ensure the uniformity of the light spot, the focal lines of the multiple pattern structures are parallel to each other.

[0029] The focusing body 1 is a rotating concentrator. The light emitted from the focus of the rotating concentrator is refracted and totally reflected by the concentrator and then emitted in parallel, thereby realizing efficient light energy collection and utilization. It is also small in size and easy to install. A stretch concentrator can also be selected according to the actual space and needs.

[0030] The inner wall and / or outer wall of the focusing body 1 is provided with patterns, and the shape, width and curvature of the patterns can be designed according to actual applications.

[0031] The light color of the light source is one or more of white light, yellow light, red light, blue light and green light. The light source of the headlights meets the requirements of GB-4785 for the light colors of lamps with different functions. When the light color of the light source is multiple, functional multiplexing is achieved. For example, when changing lanes, the turn signal lights up yellow light, when braking, it switches to red light, and when reversing, it switches to white light. Specifically, the light source may include multiple LED lamp beads, some of which are yellow light and some are white light. When yellow light is needed for turning, the yellow light source is lit, and when white light is needed for reversing, the white light source is lit. The optical form of the utility model can be flexibly applied to a variety of scenarios.

[0032] The utility model also provides a vehicle lamp, comprising the above-mentioned light-collecting structure.

[0033] In summary, in the light-collecting structure of the utility model, the light emitted by the light source is collimated by the light-collecting body and refracted to the light distribution pattern unit on the light-emitting side, and the light is collected at the focus to form a rectangular light spot, thereby improving the light effect and reducing the power consumption of the system. The rectangular light spot has a uniform light intensity distribution and stable light distribution performance. The utility model has a simple structure, is easy to implement, can effectively reduce the power consumption of the system, and saves production costs.

[0034] Since the vehicle lamp of the utility model has the light-collecting structure, it also has the advantages of the light-collecting structure.
