Description

Technical Field

[0001] This utility model relates to the technical field of thick-walled components for automotive lights, specifically to an optical structure with double thick-walled components. Background Technology

[0002] Thick-walled components for automotive headlights are wall-shaped structures made of special materials, installed inside the headlight housing to protect the light source and reflector. These thick-walled components effectively block light from entering the headlight, preventing light scattering and leakage, and improving the beam's focus and brightness.

[0003] In the existing technology, the more conventional solution is to use two PCB boards or a condenser to make a whole 45° slope. First, using two PCB boards as two independent light sources is too costly and most customers cannot accept it. In addition, the space occupied by the two PCB boards is large.

[0004] Alternatively, a separate concentrator solution can be used, but the brightest area in the center will be blocked by a baffle, resulting in significant energy loss and difficulties in data processing. In addition, the two solutions mentioned above may also lead to inconsistent brightness between the upper and lower layers, resulting in uneven light output. Utility Model Content

[0005] The purpose of this invention is to provide a double thick-walled optical structure to solve the above-mentioned technical problems.

[0006] This utility model provides the following technical solution:

[0007] A double thick-walled optical structure includes: a first thick-walled member, and a second thick-walled member disposed directly above the first thick-walled member;

[0008] The first thick-walled member and the second thick-walled member respectively have a first reflecting surface and a second reflecting surface that are obliquely arranged for reflecting light beams;

[0009] The first reflective surface includes multiple sets of adjacent first inclined surfaces and first horizontal surfaces, and the second reflective surface also includes multiple sets of second inclined surfaces;

[0010] The optical structure of the double thick-walled component also includes a light-emitting structure. Part of the parallel light beam emitted by the light-emitting structure is reflected by the first inclined surface and emitted along a horizontal light path, while another part of the parallel light beam passes through the first horizontal surface and enters the second inclined surface, where it is transformed into a horizontal light beam and emitted.

[0011] Furthermore, the angle between the first inclined plane and the second inclined plane and the horizontal plane is 45 degrees.

[0012] Furthermore, a second inclined plane is provided directly above each of the first horizontal planes, so that the transmitted light beam is evenly distributed to the second inclined plane after passing through the first horizontal plane.

[0013] Furthermore, the second reflective surface also includes multiple sets of second horizontal surfaces that are alternately connected to the second inclined surface.

[0014] Furthermore, the light-emitting structure includes a light source, and a collimation structure is disposed above the light source, so that the light beam emitted by the light source is transformed into a parallel light beam by the collimation structure.

[0015] Furthermore, the collimation structure is a condenser or a Fresnel lens.

[0016] Furthermore, a light-shielding member is provided between the first thick-walled member and the second thick-walled member.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The double thick-walled component of this utility model only requires a set of PCB-controlled light sources. The light source passes through the double thick-walled component and can achieve uniform light output. It has lower cost and requires less space. In this application, part of the light beam is transmitted to the second inclined surface through the cooperation of the first horizontal plane. There are no components blocking the center area of ​​the light source, thereby reducing the energy loss of the light source. The design of the first and second reflective surfaces ensures that the brightness of the upper and lower layers is consistent. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1As shown, this embodiment provides a double thick-walled optical structure, which includes a first thick-walled member 100 for uniformly reflecting light, and a second thick-walled member 200 located directly above the first thick-walled member 100. The second thick-walled member 200 is used to receive the light beam transmitted by the first thick-walled member 100.

[0025] Among them, such as Figure 2-3 As shown, the first thick-walled member 100 and the second thick-walled member 200 also have a first reflective surface 110 and a second reflective surface 210 respectively arranged obliquely, for reflecting the light beams irradiated along the bottom surface of the first thick-walled member 100 and the bottom surface of the second thick-walled member 200. The reflected light beams are emitted through the side surface of the first thick-walled member 100 and the side surface of the second thick-walled member 200 to form a light beam with uniform brightness.

[0026] Among them, such as Figure 1 As shown, a light-shielding member 500 is also provided between the first thick-walled member 100 and the second thick-walled member 200.

[0027] In use, a light source 400 is also provided below the first thick-walled member 100. A collimation structure 300 is provided between the light source 400 and the first thick-walled member 100. The light source 400 and the collimation structure 300 are combined to form a light-emitting structure. The light beam emitted by the light source 400 passes through the collimation structure 300 to form a parallel light beam and enters the bottom surface of the first thick-walled member 100. The collimation structure 300 can be a condenser or Fresnel lens with collimation function, or other components with collimation function. The parallel light beam entering the bottom surface of the first thick-walled member 100 is reflected by the first reflecting surface 110. Part of the light beam is emitted parallel to the side of the first thick-walled member 100 along the horizontal light path direction, and the other part of the light beam passes through the first thick-walled member 100 and enters the bottom surface of the second thick-walled member 200. After being reflected by the second reflecting surface 210, it is emitted along the horizontal light path, forming a uniform light emission effect, and the brightness of the light emission surfaces of the two thick-walled members is consistent.

[0028] As one specific implementation method, such as Figure 3 As shown, the first reflecting surface 110 includes multiple sets of alternating first inclined surfaces 110a and first horizontal surfaces 110b, and the second reflecting surface 210 also includes multiple sets of alternating second inclined surfaces 210a and second horizontal surfaces 210b. The angle between the first inclined surface 110a and the second inclined surface 210a and the horizontal surface is 45 degrees. A parallel light beam entering from the bottom surface of the first thick-walled member 100 is reflected onto the first inclined surface 110a as shown. Figure 3 The light beam shown is emitted through the side of the first thick-walled member 100 along the horizontal light path, while the parallel light beam passing through the first horizontal surface 110b passes through the horizontal surface and enters the bottom surface of the second thick-walled member 200. This part of the light beam hits the second inclined surface 210a, and this part of the light beam is reflected and emitted horizontally through the side of the second thick-walled member 200.

[0029] As one specific implementation method, such as Figure 3 As shown, each group of second inclined planes 210a is positioned directly above each group of first horizontal planes 110b, so that the light beam passing through the first horizontal plane 110b can be evenly distributed onto the second inclined plane 210a, ensuring horizontal light output.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
