Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lighting, and in particular to a reflection system. In addition, the present invention also relates to a vehicle. Background Art

[0002] With the rapid development of automotive lighting technology and consumers' increasing pursuit of lighting effects, production costs and efficiency are also urgent issues that automotive lighting suppliers need to solve. In the existing solution, after the light is emitted from the LED, it passes through a series of devices and then emerges from the light-emitting surface to achieve a more uniform lighting effect. In addition, in traditional projects, the known solutions require a large number of LEDs, which are not efficient, increase the cost of LED raw materials, and also cause complex circuit design and increased heat risks.

[0003] Chinese utility model patent CN210462871U discloses a signal light function multiplexing composite reflector device and a car, including two light guides, two light input reflectors, a light output reflector and a light output area. In the reflector device, two signal light sources with different functions are arranged one by one at the corresponding positions of the two light input reflectors. When any signal light source is started, the light beam emitted by it is reflected by the corresponding light input reflector and then enters the light guide body from the light input port, and further incident on the corresponding reflection surface of the wavy light output reflector, and is reflected by the reflection surface into the light output area, and finally emitted from the light output port, thereby showing the corresponding function of the signal light. The composite reflector device can realize the function multiplexing of signal lights with different functions, and the light is relatively uniform, avoiding the problem of poor lighting effect caused by LED defocus. In this scheme, it integrates the light emitted by different light sources and then emits it from the same light output area, so as to achieve the effect of uniform light output, but this also limits the light output range of the light to only within the light output area, and cannot be expanded to the outside.

[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figure 1 As shown, the reflection system of the basic embodiment of the present invention includes a light guide structure 2 and a reflection structure 3, wherein a light inlet 211 is provided on the light guide structure 2, and the shape of the light inlet 211 can be regular shapes such as round and square, or can be irregular shapes, and the light inlet 211 only needs to be adapted to the shape and structure of the light source 11. A PCB board 1 and a light source 11 are provided outside the light inlet 211 of the light guide structure 2, and the light source 11 is arranged corresponding to the light inlet 211. The base material of the light guide structure 2 can be selected from white PC, PC ABS or PMMA, and the light source 11 can be selected from LED light source 11, MINI LED light source 11 or Micro LED light source 11, etc. Since the reflection system is not limited to the application position of the vehicle, that is, the reflection system can be applied to the application positions such as brake lights and turn lights, the color of the light source 11 used by the light source 11 can also be determined according to the actual application scenario.

[0041] like Figure 2As shown, the reflective structure 3 is arranged on the inner side of the light entrance 211 of the light guiding structure 2, and the reflective structure 3 includes a forward reflective surface 31 and a side reflective surface 32, wherein the forward reflective surface 31 can receive the incident light emitted by the light source 11, and then emit the incident light, and the side reflective surface 32 can partially receive the incident light emitted by the forward reflective surface 31, and then the side reflective surface 32 can emit the received incident light to form the final output light. In addition, a portion of the incident light irradiated on the forward reflecting surface 31 will not be reflected onto the side reflecting surface 32. Therefore, this portion of the incident light will be directly reflected by the forward reflecting surface 31, and the incident light directly reflected by the forward reflecting surface 31 and the incident light reflected by the side reflecting surface 32 have substantially the same light emitting direction. However, through the combination of the side reflecting surface 32 and the forward reflecting surface 31, both side reflecting surfaces 32 can reflect the incident light, and the area between the two side reflecting surfaces 32 can reflect the incident light, thereby effectively expanding the light emitting range of the incident light.

[0042] In order to describe the reflection structure 3 of the reflection system in more detail and accuracy, the structures of the front reflection surface 31 and the side reflection surface 32 are described separately.

[0043] like Figure 7 As shown, the front reflective surface 31 includes a first front reflective surface 311, a second front reflective surface 312 and a third front reflective surface 313, wherein the first front reflective surface 311, the second front reflective surface 312 and the third front reflective surface 313 are combined with each other and have the same connection node. That is, two adjacent sides of the first front reflective surface 311 are respectively connected to the second front reflective surface 312 and the third front reflective surface 313, two adjacent sides of the second front reflective surface 312 are respectively connected to the first front reflective surface 311 and the third front reflective surface 313, and two adjacent sides of the third front reflective surface 313 are respectively connected to the first front reflective surface 311 and the second front reflective surface 312, so that the overall structure of the front reflective surface 31 can be formed.

[0044] like Figure 3As shown, the first front reflective surface 311, the second front reflective surface 312 and the third front reflective surface 313 are all arc-shaped reflective surfaces. Therefore, when the incident light enters the above-mentioned reflective surfaces, it will not diffuse on them again, but will converge on them. Then, after being reflected by the first front reflective surface 311 and the second front reflective surface 312, the focal length of the emitted light is determined according to the curvature of the arc-shaped reflective surface. In order to ensure that the incident light can be reflected to the first side reflective surface 321 and the second side reflective surface 322 after passing through the first front reflective surface 311 and the second front reflective surface 312, After the first side reflective surface 321 and the first front reflective surface 311 are in the maximum diffusion state, the distance between the first side reflective surface 321 and the first front reflective surface 311, and the distance between the second side reflective surface 322 and the second front reflective surface 312 is less than the focal length of the arc reflective surface. Preferably, the length between the two is set to half of the focal length of the arc reflective surface. At this time, the incident light after reflection is in the maximum diffusion degree, and then after irradiating the first side reflective surface 321 and the second side reflective surface 322, it can be completely reflected and emitted, and the incident light after diffusion is reflected and diffused again, so as to form a larger light emitting range. In addition, after multiple reflections between the front reflective surface 31 and the side reflective surface 32, the light emitting effect can be made uniform while expanding the light emitting area.

[0045] like Figure 7 or Figure 8 As shown, the side reflective surface 32 includes a first side reflective surface 321 and a second side reflective surface 322, wherein the plurality of side reflective surfaces 32 are all planes, the first side reflective surface 321 is suitable for receiving and emitting incident light reflected by the first front reflective surface 311, and the second side reflective surface 322 is suitable for receiving and emitting incident light reflected by the second front reflective surface 312. Among the front reflective surfaces 31, it is not only the first front reflective surface 311 and the second front reflective surface 312 that can reflect incident light onto the side reflective surface 32, the third front reflective surface 313 can directly emit incident light, therefore, the first side reflective surface 321 and the second side reflective surface 322 cooperate with the third front reflective surface 313 to emit incident light irradiated thereon, so as to form the final light emitting effect. It should be noted that the number of the side reflective surfaces 32 and the front reflective surfaces 31 is not limited to the number described above, and the number of the side reflective surfaces 32 and the front reflective surfaces 31 can be controlled and adjusted according to actual needs.

[0046] like Figure 1 and Figure 4As shown, the light guide structure 2 includes a plurality of light guide units 23, which are arranged linearly, and each light guide unit 23 is provided with at least one light inlet 211, and the shortest spacing between the light inlets 211 provided on adjacent light guide units 23 is equal. An aluminum layer is also plated on the inner side of the light guide structure 2, and a reflective structure 3 is correspondingly provided in the plurality of light inlets 211 provided on the light guide unit 23, so as to ensure that the incident light entering from the light inlet 211 can be completely received and reflected. In addition, the provision of the aluminum layer can ensure the uniformity of the light output. It is worth mentioning that the multiple light guide units 23 constituting the light guide structure 2 can be integrally formed or cast separately, that is, the multiple light guide units 23 contained in the light guide structure 2 can be detachably connected. At this time, the multiple light guide units 23 are independent of each other, and the reflective structure 3 set in each light guide unit 23 can be independently set according to actual needs, and then the multiple light guide units 23 are combined according to needs to form the light guide structure 2 as a whole. The above-mentioned setting method can make the overall light output effect more diversified.

[0047] like Figures 3 to 6 As shown, the light guide structure 2 at least includes a lower side surface 22. In the reflection system, the light guide structure 2 includes an upper side surface 21, a lower side surface 22, and a connection PCB board 1 connecting the upper side surface 21 and the lower side surface 22, and a pattern structure is also provided on the lower side surface 22. The arrangement of the pattern structure can diffuse the incident light more evenly. Of course, the reflection of the incident light can also be achieved without the upper side surface 21 and the connection PCB board 1. It is only necessary to ensure that the incident light emitted by the light source 11 can be irradiated onto each reflection surface of the reflection structure 3. In addition, according to the actual effect and use requirements, local leather grains and patterned aluminum plating can be provided on the inner side of the light guide structure, and the pattern can be provided in the form of horizontal stripes, vertical stripes or corn grain patterns, so that the diffusion of light is more uniform. In addition, the connection relationship between the reflection structure 3 and the light guide structure 2 can be set according to actual needs, and the above-mentioned pattern structure can also be provided on the surface of the reflection structure 3 to increase the light diffusion range.

[0048] like Figure 8As shown, the side reflection surfaces 32 are respectively arranged on both sides of the front reflection surface 31, and one end of the side reflection surface 32 is arranged close to the front reflection surface 31, and the other end is arranged away from the front reflection surface 31, that is, an angle is formed between the side reflection surface 32 and the front reflection surface 31. Preferably, an angle of about 90° is formed between the side reflection surface 32 and the front reflection surface 31, wherein the angles between the first side reflection surface 321 and the second side reflection surface 322 and the light outlet are both about 45°. Of course, the side reflection surfaces 32 on both sides can also adjust the angles with the front reflection surface 31 and the light outlet according to actual needs, and the angles between the side reflection surfaces 32 on both sides and the front reflection surface 31 do not need to be the same. At this time, the length of the overall reflection surface is the distance between the side reflection surfaces 32 on both sides, and the reflection surface of the currently used reflection system is only the length of the forward reflection surface 31 in this reflection system. Therefore, the length of the reflection system can be nearly doubled compared to the traditional reflection system, that is, the light output area is expanded to three times the original. In addition, due to the coordination of the side reflection surface 32 and the forward reflection surface 31, it is not necessary to use more LED light sources 11 to achieve a uniform light output effect, and the use of LED light sources 11 is reduced, which can reduce costs and increase efficiency.

[0049] The vehicle of the present invention adopts the reflection system of the present invention, and thus also has the above advantages.
