Description

Technical Field

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

[0002] With the rapid development of automobile lighting technology, users' pursuit of lamp shapes has become increasingly diversified, and aesthetics is also an important consideration. Therefore, simple appearance is also the development direction of various OEMs. Minimalist light output end and uniform lighting are also difficulties that need to be overcome in the field of automotive technology. At present, most mainstream solutions are thick-walled parts, reflectors or light guides.

[0003] Many current headlights use LEDs as light sources. Due to the characteristics of LED light emission, in order to meet the appearance requirements of the headlights and solve problems such as the uniformity of the light output of the headlights, it is often necessary to adopt complex optical path designs to achieve uniform light output in the required direction, which complicates thick-walled parts, reflectors or light guides and increases manufacturing costs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a uniform thick-walled structure and a car light containing the same, which emits light through refraction by two lens surfaces cooperating with each other. It has high light efficiency and good lighting uniformity, and can expand or reduce the light intensity distribution spot. It is visually transparent and has universality.

[0005] The utility model provides a uniform thick-walled component structure, comprising:

[0006] A first lens, wherein a light-emitting end of the first lens has a first focus;

[0007] a second lens, wherein the light incident end of the second lens has a second focus, and the first lens and the second lens have the same height;

[0008] When light is emitted from the light-emitting end of the first lens and converges at the first focus, it enters the light-incoming end of the second lens through the first focus and is emitted from the light-emitting end of the second lens.

[0009] The utility model discloses a uniform thick-walled component structure, which emits light after refraction through the cooperation between the first lens and the second lens, has high light efficiency and good lighting uniformity. When the first lens and the second lens are at the same height, the focal lengths of the first lens and the second lens are adjusted to be different, and the light spot distribution range can be adjusted according to the relative relationship between the focal lengths of the first lens and the second lens.

[0010] Furthermore, the first focus and the second focus overlap, which can maximize the light extraction efficiency and reduce system power consumption.

[0011] Furthermore, in order to ensure uniform light emission, the focal length of the first lens is equal to the focal length of the second lens.

[0012] Furthermore, in order to increase the distribution range of the light spot angle, the focal length of the first lens is smaller than the focal length of the second lens.

[0013] Furthermore, in order to reduce the distribution range of the light spot angle, the focal length of the first lens is greater than the focal length of the second lens.

[0014] Furthermore, the light output end of the first lens is an arc surface that is arched from the light input end side toward the light output end side.

[0015] Furthermore, the light incident end of the second lens is an arc surface that arches from the light emitting end side toward the light incident end side.

[0016] Furthermore, the first lens is a focusing lens, and the second lens is a collimating lens.

[0017] Furthermore, the uniform thick-walled component structure of the utility model further includes:

[0018] A light focusing portion, a light source is disposed on one side of the light focusing portion;

[0019] A total reflection part, wherein the total reflection part is arranged at the other side of the focusing part, and the reflection part is provided with a total reflection surface. The light emitted by the light source is incident on the total reflection surface through the focusing part, and is emitted from the first lens after total reflection through the total reflection surface.

[0020] The utility model also provides a vehicle lamp, comprising the above-mentioned uniform thick-walled component structure.

[0021] The beneficial effects of the utility model are:

[0022] The utility model discloses a uniform thick-walled component structure, after the light is refracted from the light output end of the first lens, it enters the air, is refracted again through the light input end of the second lens, and finally is emitted through the light output end of the second lens. The light is output after being refracted by the first lens and the second lens in cooperation with each other, and the lighting uniformity is good. When the first lens and the second lens are at the same height, the focal lengths of the first lens and the second lens are adjusted to be different, and the light spot distribution range can be adjusted according to the relative relationship between the focal lengths of the first lens and the second lens, and the first focus and the second focus coincide, so that the light output efficiency can be maximized and the power consumption of the system can be reduced.

[0023] The vehicle lamp of the utility model has a uniform thick-walled component structure, and therefore has the advantages of the uniform thick-walled component structure.

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.

[0035] like Figure 1 , which is the first embodiment of the utility model. The utility model provides a uniform thick-walled component structure, including: a first lens 1 and a second lens 2.

[0036] The light output end of the first lens 1 has a first focus 11, the light input end of the second lens 2 has a second focus, and the first lens 1 and the second lens 2 have the same height; when light is emitted from the light output end of the first lens 1 and converges at the first focus 11, it is emitted into the light input end of the second lens 2 through the first focus 11 and emitted from the light output end of the second lens 2.

[0037] The utility model discloses a uniform thick-walled structure, which emits light after refraction through the cooperation between the first lens 1 and the second lens 2, has high light efficiency and good lighting uniformity.

[0038] The first focus 11 coincides with the second focus, which can maximize the light extraction efficiency and reduce system power consumption.

[0039] The focal length of the first lens 1 is equal to the focal length of the second lens 2, so that uniform light output is achieved and high light efficiency is achieved.

[0040] The light output end of the first lens 1 is an arcuate surface that arches from its light input end side toward its light output end side, and the light input end of the second lens 2 is an arcuate surface that arches from its light output end side toward its light input end side.

[0041] For the convenience of material selection, the first lens 1 is a focusing lens and the second lens 2 is a collimating lens.

[0042] In order to increase the uniformity of the emitted light, a pattern is provided on the light emitting end of the second lens 2 .

[0043] like Figure 2 As shown, it is the second embodiment of the utility model, which differs from the first embodiment in that the focal length of the first lens 1 is smaller than the focal length of the second lens 2, and the angle distribution range of the light spot can be enlarged, that is, the observation angle formed by the emitted light is larger.

[0044] like Figures 3 to 6 As shown, it is the third embodiment of the utility model, which is different from the first embodiment in that the focal length of the first lens 1 is greater than the focal length of the second lens 2, and the angle distribution range of the light spot can be adjusted to be smaller, that is, the observation angle formed by the emitted light is smaller.

[0045] The uniform thick-walled structure also includes: a focusing part 3 and a total reflection part 4. A light source is arranged on one side of the focusing part 3, and the total reflection part 4 is arranged on the other side of the focusing part 3. The reflection part is provided with a total reflection surface. The light emitted by the light source is incident on the total reflection surface through the focusing part 3, and is emitted from the first lens 1 after total reflection through the total reflection surface.

[0046] In the third embodiment of the present utility model, in order to reduce consumables and reduce production costs, the first lens 1 uses the upper half above the first focus 11, and the second lens 2 uses the lower half below the first focus 11, such as Figure 4 As shown, the arrow line segment in the figure is a light path diagram. When the light is emitted from the light output end of the first lens 1 and converges at the first focus 11, it enters the light input end of the second lens 2 through the first focus 11 and is emitted from the light output end of the second lens 2.

[0047] The utility model also provides a vehicle lamp, comprising the above-mentioned uniform thick-walled component structure.

[0048] In summary, the utility model has a uniform thick-walled structure, in which light is refracted from the light output end of the first lens, enters the air, is refracted again through the light input end of the second lens, and finally, is emitted through the light output end of the second lens. The light is refracted by the cooperation between the first lens and the second lens, and has high luminous efficiency and good lighting uniformity. When the heights of the first lens and the second lens are the same, the focal lengths of the first lens and the second lens can be adjusted to be different, and the light spot distribution range can be adjusted according to the relative relationship between the focal lengths of the first lens and the second lens.
