[0036] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for the purpose of explaining the present application, and should not be understood as a limitation of the present application.

[0037] The core of the present application is to provide a vehicle lamp device, which uses the light transmission to light the molding area, thereby reducing the use of light sources and saving the energy consumption of the vehicle.

[0038] The present application also provides a vehicle.

[0039] In order to enable those skilled in the art to better understand the technical solutions provided by the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0040] Specifically, please refer to the optical structure cross-sectional view shown in Figures 1-2 The vehicle lamp device provided by the present application includes a light source 105, a reflector 104, a transparent light guide plate 102, and a molding area B.

[0041] The reflector 104 has a first end and a second end. The main function of the first end of the reflector 104 is to maximize the light rays emitted by the light source 105 into a strong light beam to increase the irradiation distance. As shown in Figure 1 The first end of the reflector 104 is a concave mirror in the shape of a bowl, which can collect as many light rays emitted by the light source 105 as possible, and aggregate these light rays into a very strong light beam from the inner mirror 103 to a far place, so that the driver can see the road conditions farther away when driving at night, and ensure the safety of driving.

[0042] The transparent light guide plate 102 is used to transmit the incident light rays to the light emitting surface. The transparent light guide plate 102 is a bent plate in the shape of L, which includes a first end and a second end connected to each other, and the first end and the second end are connected at a certain angle to form an L-shaped structure. The first end of the transparent light guide plate 102 is overlapped on the outer side of the second end of the reflector 104, forming an overlapping area A as shown in Figure 2 The side surface of the first end of the transparent light guide plate 102 / bent plate faces the light source 105 as the light incident surface. The side surface of the second end of the transparent light guide plate 102 faces the light emitting direction of the vehicle lamp as the light emitting surface.

[0043] The molding area B is arranged on the light emitting surface of the second end of the transparent light guide plate 102.

[0044] The light exit surface of the light source 105 faces the first end of the reflector 104 and the first end of the transparent light guide plate 102.

[0045] The angle configuration of the transparent light guide plate 102 is configured to enable part of the direct light of the light source 105 and part of the reflected light of the reflector 104 to enter from the first end, continuously conduct reflection between the first end and the second end, and exit from the light exit surface of the second end. It should be noted that, in order to achieve the above effect, points and surfaces are made on the light path between the first end and the second end of the transparent light guide plate 102, so that the light forms total reflection after entering the light guide plate, and the pattern that destroys total reflection is arranged on the light exit surface when the light reaches the second end, and the light exits from the light exit surface.

[0046] It should also be noted that, in this article, “outside” or “front” refers to the direction towards the outside of the vehicle, and by analogy, “inside” or “back” refers to the direction towards the inside of the vehicle.

[0047] The vehicle lamp device provided by the utility model has reasonable design of the shape and structure of the transparent light guide plate 102, so that part of the direct light of the light source 105 and part of the reflected light of the reflector 104 can enter from the first end of the transparent light guide plate 102, continuously conduct total reflection between the first end and the second end, and exit from the light exit surface of the second end. At the same time, arranging the modeling area B on the light exit surface of the transparent light guide plate 102 can achieve a unique light effect and improve the recognition and aesthetics of the vehicle.

[0048] The light source 105, the reflector 104 and the transparent light guide plate 102 cooperate with each other to effectively guide and distribute the light emitted by the light source 105 in the transparent light guide plate 102, so that the illumination range is wider and more uniform, thereby improving the safety of driving at night or in a dark environment. The modeling area B is illuminated by using the light transmission, without the need to additionally increase the light source for illuminating the modeling area B, thereby reducing the use of the light source of the whole vehicle and saving the energy consumption of the vehicle.

[0049] In specific embodiments, the second end of the reflector 104 can be lapped with the transparent light guide plate 102, and the transparent light guide plate 102 is designed into different forms of structures according to the shape. When the transparent light guide plate 102 is an L-shaped bending plate, the second end of the reflector 104 not only laps the first end of the transparent light guide plate 102, but also extends and exceeds the back surface of the second end of the transparent light guide plate 102, and the excess part is bent, which can increase the efficiency of light exit of the transparent light guide plate 102.

[0050] The scheme also includes an inner matching lens 103, which is arranged outside the light source 105, the first end of the reflector 104 and the first end of the transparent light guide plate 102. The inner matching lens 103 is a car lamp lens, which mainly optimizes the light distribution and intensity to improve the lighting effect and safety.

[0051] As shown in Figure 1 The first end of the reflector 104 is arranged on one side of the light source 105, and the inner matching lens 103 is arranged on the other side of the light source 105; the first end of the transparent light guide plate 102 is located between the first end of the reflector 104 and the inner matching lens 103, and is arranged in parallel with the line board of the light source 105.

[0052] On the basis of the above specific embodiments, the first end and the second end of the reflector 104 are arranged vertically to facilitate better light propagation.

[0053] Further, the case also includes a base and an outer cover 101, and the outer cover 101 and the base form a containing cavity for mounting the components of the car lamp device, and the outer cover 101 is used for emitting light beams. The light emitting directions of the inner matching lens 103 and the transparent light guide plate 102 are both towards the outer cover 101, and the main light emitting areas of the inner matching lens 103 and the transparent light guide plate 102 are distributed in different areas of the outer cover 101.

[0054] The transparent light guide plate 102 can assist the outer cover 101 to better distribute and guide the light. The outer cover 101 also has strong light condensing ability, which can condense scattered light into parallel light beams, and the transparent light guide plate 102 further optimizes the light propagation path, so that the road surface in front of the car is well and uniformly illuminated, the lighting effect is enhanced, and the illumination angle of the light is limited to avoid light scattering to other vehicles, thereby improving driving safety.

[0055] In order to prevent the light of the light source 105 from directly emitting between the inner matching lens 103 and the transparent light guide plate 102, the inner matching lens 103 and the transparent light guide plate 102 are connected by a light shielding baffle. The light irradiation range of the car lamp can be accurately controlled to avoid light scattering to unnecessary areas, reduce the glare effect on the drivers of oncoming vehicles, and affect the lighting effect.

[0056] In an embodiment, the light source 105 is an LED lamp, and in other embodiments, the light source 105 can also be other light emitting devices, which are not described here. The light source 105 can also include a PCBA board (i.e. a car lamp line board).

[0057] In other embodiments, a light guide plate support fixed on the reflector 104 is also included, which is arranged on the back of the transparent light guide plate 102 to provide support.

[0058] In specific embodiments, the modeling area B is a characteristic line and / or a characteristic surface arranged on the transparent light guide plate 102, the number of the characteristic line and / or the characteristic surface can be one or more, and the specific modeling can also be adjusted randomly according to the lighting demand, to form various effect patterns, so as to ensure the consistency of the overall lighting effect of the lamp in different situations. The residual light of the light source 105 in the functional area is borrowed to light the characteristic line or the characteristic surface of the demand area by using the light transmission. Figure 7 An effect pattern after lighting is shown.

[0059] In addition, the utility model also provides a vehicle, including the vehicle lamp device in above-mentioned specific embodiments. The vehicle lamp device can be a signal lamp arranged at the front, rear or side of the vehicle.

[0060] In summary, the vehicle lamp device and the vehicle applying the vehicle lamp device provided by the utility model do not need to arrange any light source for the modeling area B to be lighted, but use the light transmission characteristics, extend the design of the optical surface through the part design, and light the residual light of the corresponding functional area, to realize the lighting of the characteristic line or the surface of the modeling demand. The design can effectively save the arrangement of the LED light source and the design of the electronic circuit, and the energy consumption, the weight and the cost of the lamp are also reduced.
