[0031] Modern vehicles have a variety of lighting devices with rich functions. Thick-walled parts are often used in lighting devices because of their high light efficiency and good lighting effect. Thick-walled parts are mainly divided into direct-emitting and side-emitting structures.

[0032] See also Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of a first embodiment of a light emitting device 1 provided in the present application, Figure 2 1 is a schematic structural diagram of a second embodiment of the light emitting device 1 provided in the present application, in which the dotted line represents the propagation path of the initial light beam 210 emitted by the light source 20 in the thick-walled member.

[0033] In one embodiment of the present application, the light emitting device 1 adopts Figure 1 In the direct-emitting thick-walled member structure shown, the first thick-walled member 30 and the second thick-walled member 50 are arranged close to each other in the Z direction and arranged in the X direction. The first exit surface 330 and the second exit surface 530 are both arranged in the X direction on the right side of the thick-walled member, and the light source 20 is arranged in the X direction on the left side of the thick-walled member. The concentrator 80 is embedded in the first thick-walled member 30 and the second thick-walled member 50 and is located on the side close to the light source 20. The initial light beam 210 emitted by the light source 20 is first collected and collimated by the concentrator 80 and propagates in the X direction, and then emitted through the first exit surface 330 and the second exit surface 530.

[0034] Another embodiment of the present application is to use Figure 2 In the side-emitting thick-walled member structure shown, the first thick-walled member 30 and the second thick-walled member 50 are arranged close to each other in the Z direction and arranged in the X direction. The first exit surface 330 and the second exit surface 530 are both arranged in the X direction on the right side of the thick-walled member, the light source 20 is arranged in the Z direction, and the concentrator 80 is embedded in the first thick-walled member 30 and the second thick-walled member 50 and close to the light source 20. The initial light beam 210 emitted by the light source 20 is collected and collimated by the concentrator 80 and then propagates along the Z direction to the first reflection surface 310 and the second reflection surface 510. After being reflected, the propagation direction is refracted and propagates along the X direction to the first exit surface 330 and the second exit surface 530 to emit light.

[0035] The light emitting device 1 adopting the direct-emitting thick-walled structure occupies less space in the Z direction, but because the initial light beam 210 is not reflected and the space in the X direction is limited, the lighting uniformity and lighting effect are insufficient. The light emitting device 1 adopting the side-emitting thick-walled structure has better lighting uniformity and lighting effect because the initial light beam 210 is reflected, but it occupies a certain space in the Z direction and needs to be configured with multiple light sources 20, which is costly and occupies a certain space. It is difficult to assemble and process the light emitting device 1 under the condition of limited space.

[0036] See also Figure 3 , Figure 4 , Figure 3is a schematic structural diagram of a third embodiment of the light emitting device provided in the present application, Figure 4 yes Figure 3 A schematic cross-sectional structure diagram of a light emitting device is shown.

[0037] In order to solve the above-mentioned related problems, the present application provides a lighting device 1 and a vehicle. The lighting device 1 includes a light source 20, a first thick-walled member 30 and a second thick-walled member 50; the light source 20 is used to emit an initial light beam 210 along an incident direction Z; the first thick-walled member 30 is located on the optical path of the initial light beam 210, the first thick-walled member 30 is used to receive the initial light beam 210, the first thick-walled member 30 includes a first reflecting surface 310 and a first transmitting surface 320, part of the initial light beam 210 is transmitted from the first transmitting surface 320, and the rest of the initial light beam 210 is reflected by the first reflecting surface 310 along an exit direction X; The second thick-walled member 50 is located on the side of the first thick-walled member 30 away from the light source 20. The second thick-walled member 50 includes a second reflecting surface 510 and a second transmitting surface 520. The second transmitting surface 520 is arranged opposite to the first transmitting surface 320 in the incident direction Z. The second transmitting surface 520 receives a portion of the initial light beam 210 transmitted through the first transmitting surface 320. The second reflecting surface 510 is used to reflect the portion of the initial light beam 210 received by the second transmitting surface 520 along the emitting direction X, wherein the emitting direction X is different from the incident direction Z.

[0038] The initial light beam 210 emitted by the light source 20 first enters the first thick-walled member 30, wherein a portion of the initial light beam 210 propagates to the first reflective surface 310 and is reflected, and the propagation direction of the initial light beam 210 is deflected. After being reflected, the initial light beam 210 propagates along the emission direction X. Another portion of the initial light beam 210 propagates through the first transmission surface 320 and is emitted to the second transmission surface 520 and enters the second thick-walled member 50. At this time, the propagation direction of the initial light beam 210 has not changed, and there is a certain interval between the first transmission surface 320 and the second transmission surface 520. When the initial light beam 210 propagates to the second reflective surface 510, it is reflected and propagates along the emission direction X. At this time, the propagation direction of the initial light beam 210 changes. The light source 20 is close to the first thick-walled member 30 and away from the second thick-walled member 50. By such an arrangement, the initial light beam 210 emitted by the light source 20 is divided into two parts, and the light is propagated in the first thick-walled member 30 and the second thick-walled member 50 respectively, so that the first thick-walled member 30 and the second thick-walled member 50 share a light source 20, which reduces the cost of the light source 20 and saves assembly space, thereby reducing the difficulty of assembly and processing. The light source 20 may include a PCB substrate and LED lamp beads, the LED lamp beads are used to emit the initial light beam 210, and the PCB substrate is used to control the lamp beads. The LED lamp beads can be welded and fixed on the PCB substrate, the number of LED lamp beads can be 13, and they can be evenly arranged on the PCB substrate at a spacing of 10 mm, and the thickness of the PCB substrate can be 1.7 mm. The number of LED lamp beads, the spacing between the LED lamp beads, and the thickness of the PCB substrate can also be other values, depending on the actual situation, and are not limited to this application here.

[0039] The first reflecting surface 310 and the second reflecting surface 510 are arranged at an angle of 40 to 50 degrees with the incident direction Z.

[0040] The first reflection surface 310 of the first thick-walled member 30 and the second reflection surface 510 of the second thick-walled member 50 are mainly used to reflect the initial light beam 210 emitted by the light source 20 to increase the lighting uniformity. The propagation direction of the initial light beam 210 after reflection is folded and propagates in the thick-walled member along the emission direction X. The first reflection surface 310 and the second reflection surface 510 can be set at an angle of 45 degrees to the incident direction Z of the initial light beam 210, or at other angles, depending on the actual situation.

[0041] The emitting direction X and the incident direction Z are arranged at an angle of 90 degrees. The emitting direction X is usually arranged at an angle of 90 degrees to the incident direction Z, so that the light source 20 is assembled in the Z direction, saving assembly space. The propagation distance of the initial light beam 210 along the emitting direction X in the first thick-walled member 30 and the second thick-walled member 50 is usually longer than the propagation distance of the initial light beam 210 along the incident direction Z, because the assembly space of the light emitting device 1 in the Z direction has certain limitations.

[0042] Furthermore, the light emitting device 1 includes a thick-walled member bracket 40 , which is located between the first thick-walled member 30 and the second thick-walled member 50 , and is used to isolate the initial light beam 210 between the first thick-walled member 30 and the second thick-walled member 50 .

[0043] The first thick-walled member 30 and the second thick-walled member 50 are relatively close to each other. Although most of the initial light beam 210 propagates in the first thick-walled member 30 and the second thick-walled member 50, a small part of the initial light beam 210 may still propagate into the adjacent thick-walled member, which will affect the lighting effect. The thick-walled member bracket 40 between the first thick-walled member 30 and the second thick-walled member 50 is made of white high-reflectivity material, which can reflect the initial light beam 210 propagating on the thick-walled member bracket 40 back into the first thick-walled member 30 and the second thick-walled member 50, avoiding the initial light beams 210 in the first thick-walled member 30 and the second thick-walled member 50 from crosstalking each other, further improving the lighting effect.

[0044] The thick-walled component support 40 covers the first reflecting surface 310 and is extended along the emitting direction X. The thick-walled component support 40 is provided above the first reflecting surface 310 and above the path of the first thick-walled component 30 propagating along the emitting direction X. There may be a certain interval between the thick-walled component support 40 and the first thick-walled component 30 and the second thick-walled component 50, which is used to isolate the initial light beam 210 between the first thick-walled component 30 and the second thick-walled component 50 to prevent the propagating initial light beams 210 from affecting each other. Since the second thick-walled component 50 needs to receive the initial light beam 210 through the first transmitting surface 320, the thick-walled component support 40 is not provided above the first transmitting surface 320.

[0045] Furthermore, the light emitting device 1 includes a condenser 80 , which is located on the optical path of the initial light beam 210 and is used for condensing the initial light beam 210 and projecting it onto the first reflective surface 310 and the first transmissive surface 320 .

[0046] The initial light beam 210 emitted by the light source 20 will first enter the first thick-walled member 30 , and the initial light beam 210 emitted by the LED lamp bead will be scattered, and many initial light beams 210 will deviate from the incident direction Z. In order to enhance the lighting effect, a condenser 80 will be arranged on the optical path of the initial light beam 210 to condense and collimate the initial light beam 210 and propagate along the incident direction Z to the first reflective surface 310 and the first transmissive surface 320 .

[0047] The concentrator 80 is embedded in the first thick-walled member 30. Embedding the concentrator 80 in the first thick-walled member 30 can save assembly space. At the same time, the first thick-walled member 30 is placed above the light source 20 with a certain interval, which can be 0.5 mm or other values.

[0048] Furthermore, the first thick-walled component 30 also includes a first exit surface 330, which is used to receive the initial light beam 210 reflected by the first reflective surface 310, and the first exit surface 330 is corrugated; the second thick-walled component 50 also includes a second exit surface 530, which is used to receive the initial light beam 210 reflected by the second reflective surface 510, and the second exit surface 530 is corrugated.

[0049] The first exit surface 330 and the second exit surface 530 are the light outlets for propagating the initial light beam 210, and the initial light beam 210 is transmitted from here. In order to enhance the lighting effect, a pattern can be arranged on the first exit surface 330 or the second exit surface 530. A vertical stripe pattern can be arranged to make the initial light beam 210 diffuse and propagate left and right on the exit surface, or a corn grain pattern can be arranged to make the initial light beam 210 diffuse and propagate up and down and left and right on the exit surface, thereby improving the uniformity of lighting. Similarly, vertical stripe patterns or corn grain patterns can be arranged on the first reflective surface 310 of the first thick-walled member 30, the first transmissive surface 320, the second reflective surface 510 and the second transmissive surface 520 of the second thick-walled member 50, and on the concentrator 80, thereby increasing the uniformity of lighting.

[0050] See also Figure 5 , Figure 5 1 is a schematic diagram of the disassembled structure of the fourth embodiment of the light emitting device provided by the present application. Further, the light emitting device 1 includes a housing 10, a decorative frame 60 and a mask 70, the housing 10 is formed with a receiving groove 90, the light source 20, the first thick-walled member 30 and the second thick-walled member 50 are located in the receiving groove 90, the decorative frame 60 and the mask 70 are located at the notch of the receiving groove 90, the mask 70 is further away from the receiving groove 90 than the decorative frame 60, and the decorative frame 60 and the mask 70 are used to receive and transmit the initial light beam 210 reflected by the first reflective surface 310 and the second reflective surface 510.

[0051] The housing 10 has the function of protecting the components of the light emitting device 1. At the same time, the housing 10 is hollow inside to form a receiving groove 90 to wrap the first thick-walled member 30, the second thick-walled member 50 and the light source 20, so that the initial light beam 210 can be transmitted and emitted through the decorative frame 60 and the mask 70. The decorative frame 60 and the mask 70 can be arranged in close contact with the first exit surface 330 and the second exit surface 530. After the light beam is reflected by the first reflection surface 310 and the second reflection surface 510, it propagates in the thick-walled member and is transmitted from the exit surface, and then propagates to the outside through the mask 70 and the decorative frame 60. The decorative frame 60 has a decorative function, and the mask 70 can protect the first exit surface 330 and the second exit surface 530.

[0052] Through the above arrangement, the initial light beam 210 is divided into two parts for propagation, one of which propagates in the first thick-walled member 30; the other part is emitted through the first transmission surface 320 of the first thick-walled member 30, and then enters the second thick-walled member 50 through the second transmission surface 520 of the second thick-walled member 50 for propagation; thus, the first thick-walled member 30 and the second thick-walled member 50 share a light source 20, which reduces the cost of LED lamp beads and saves assembly space, thereby reducing the difficulty of assembly and processing. The thick-walled member bracket 40 arranged between the first thick-walled member 30 and the second thick-walled member 50 can also avoid the problem of mutual crosstalk between the initial light beams 210, further improving the lighting effect.

[0053] The present application also provides a vehicle, which includes the above-mentioned light-emitting device 1. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The vehicle using the above-mentioned light-emitting device 1 can reduce the use of LED lamp beads while ensuring the lighting effect, reduce costs, save vehicle assembly space, and reduce the difficulty of vehicle assembly and processing.
