TECHNICAL FIELD
[0001] The utility model belongs to the technical field of car light, especially relates to a car signal light optical system and vehicle. BACKGROUND
[0002] With the continuous development of automobile technology, the design of automobile signal light is also constantly pursuing innovation and beauty. At present, a kind of automobile signal light with dazzling lighting effect appears on the market, and the dazzling pattern surface is usually designed on the light emitting surface of car light. However, this design has significant defects. Since the dazzling pattern surface is located on the light emitting surface, it will interfere with the normal propagation path of light, thereby affecting the light distribution performance of signal light. Specifically, this design will cause the light distribution pattern of the turn signal and daytime running light to deviate from the center position required by the car light, and thus cannot meet the strict requirements of relevant regulations on the light distribution performance of automobile signal light.
[0003] In the existing thick-walled light guide structure design, there is an irreconcilable contradiction between meeting the regulatory requirements of turn signal and daytime running light function and realizing the dazzling lighting effect. On the one hand, the regulations have clear and strict provisions on the light distribution performance of automobile signal light to ensure driving safety and accurate signal transmission; on the other hand, the realization of dazzling lighting effect often requires special design of the light emitting surface, which will inevitably affect the light distribution performance. This contradiction makes engineers face great challenges in the design process, and it is often difficult to meet the regulatory requirements and aesthetic needs at the same time.

[0042] The embodiments of the present application will be 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 referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.
[0043] The core of the present application is to provide an automobile signal lamp optical system and a vehicle, which can simultaneously meet the requirements of bright lighting effect and signal lamp regulations.
[0044] 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.
[0045] Specifically, the present application provides an automobile signal lamp optical system, which comprises a light source 100, a first thick-walled part 210 and a second thick-walled part 220.
[0046] One side wall of the first thick-walled part 210 is a reflecting surface 213, and the other side wall of the first thick-walled part 210 opposite to the reflecting surface 213 is a first light-out surface, and the first light-out surface is sequentially provided with a first pattern surface 211 and a second pattern surface 212.
[0047] The second thick-wall piece 220 is provided with a third pattern surface 221 for presenting a sparkling lighting effect on one side wall of the optical channel. The second thick-wall piece 220 is further provided with a second light inlet surface opposite to the first light outlet surface, and a second light outlet surface 223 adjacent to the third pattern surface 221 and opposite to the first light outlet surface, the second light inlet surface being opposite to the first light outlet surface and being spaced apart by a certain distance.
[0048] The light source 100 is opposite to the first light inlet surface 214 of the first thick-wall piece 210. The light source 100 is used for providing initial light, and is an LED lamp. In other embodiments, the light source can also be a halogen lamp or other light-emitting device, which is not described herein. The light source 100 is welded on a circuit board, and a light-emitting surface of the light source 100 is opposite to the first thick-wall piece 210.
[0049] The angle of the first pattern surface 211 is configured to guide the light to the third pattern surface 221, and the angle of the second pattern surface 212 is configured to guide the light to be emitted along the second light outlet surface 223.
[0050] After the light source 100 is turned on, the diffused light emitted by the light source 100 enters the first thick-wall piece 210 through the first light inlet surface 214, changes the propagation direction after being reflected by the reflecting surface 213, and part of the light propagating in the first optical channel 215 is refracted by the first pattern surface 211, enters the second thick-wall piece 220 through the second light inlet surface, is reflected by the third pattern surface 221, and is emitted from the second thick-wall piece 220 at a certain diffusion angle, presenting a sparkling lighting effect. Another part of the light propagating in the first optical channel 215 (propagating in the first optical channel in a state close to parallel light) passes through the second pattern surface 212 and the second thick-wall piece 220 in turn, part of the light passing through the second pattern surface 212 is horizontally emitted from the second light outlet surface 223, and the remaining part of the light passing through the second pattern surface 212 is reflected by the third pattern surface 221 and forms a sparkling lighting effect, producing a signal light type conforming to the standards of day running light, position light and turn signal.
[0051] The automobile signal light optical system provided by the utility model has the following advantages. The first pattern surface 211 and the second pattern surface 212 of two different pattern types are arranged on the light outlet surface of the first thick-wall piece 210. The first pattern surface 211 can guide the light to the third pattern surface 221 of the second thick-wall piece 220, so that the emitted light of the second thick-wall piece 220 presents a sparkling lighting effect. Meanwhile, the second pattern surface 212 can horizontally emit most of the light through the second thick-wall piece 220, so as to meet the light intensity and light type requirements of regulations and the uniformity requirements of customers. In addition, the second pattern surface can also guide a small part of the light to enter the third pattern surface, be reflected and form a sparkling lighting effect.
[0052] In a specific embodiment, the third pattern surface 221 is arranged on the lower surface of the second thick-wall member 220. The third pattern surface 221 is illuminated by the first pattern surface 211 of the first thick-wall member 210 with a special diffusion angle, so that the diamond-like sparkling effect can be observed under natural light and after illumination. Of course, the third pattern surface 221 can also be arranged around the second optical channel 222 of the second thick-wall member 220.
[0053] In order to prevent the high heat generated by the light source 100 from damaging the optical member, the light emitting surface of the light source 100 has a preset distance from the first light entrance surface 214 of the first thick-wall member 210, which can be 1-2 mm.
[0054] In a specific embodiment, as shown in FIG. 2, the reflection surface 213 is a concave curved surface. The curved surface can be an ellipsoidal surface, a parabolic surface, or other specially designed curved surface. According to different forms of the first light entrance surface 214, the reflection surface 213 can also have various forms. As long as the light can be totally reflected on the curved surface and the reflected light is directed to the first light exit surface of the first thick-wall member 210, the shape of the reflection surface 213 is within the scope of protection. Figure 1
[0055] The diffusion pattern enables a certain degree of light mixing in the lateral direction when the light from different light entrance units propagates in the optical channel, so as to enhance the uniformity of the illumination effect. It should be noted that the lateral direction herein refers to the tangent direction of each point on the modeling center line of the modeling surface (i.e., the base surface of the light exit pattern surface). The reflection surface 213 can change the direction of the light from the light source 100, so that the light can uniformly irradiate the light exit pattern surface in the longitudinal direction after propagating in the optical channel. The longitudinal direction herein refers to the direction perpendicular to the lateral direction on the modeling surface.
[0056] The first pattern surface 211 is a plurality of continuously arranged convex surfaces, which can be corn kernel patterns or outward convex arc surfaces, so as to produce signal light patterns conforming to the standards of day running lights, position lights and turn signals. Specifically, the continuously arranged convex surfaces can be diffusion patterns composed of regularly arranged strips, rectangles or hexagons, or special diffusion angle patterns can be added to guide the light to the third pattern surface 221.
[0057] Similarly, the second pattern surface 212 can also be a plurality of continuously arranged convex surfaces, which can be corn kernel patterns or outward convex arc surfaces.
[0058] The second light entrance surface is a smooth plane or a plurality of continuously arranged convex surfaces, which can be corn kernel patterns. The first light entrance surface 214 can be a plane, a cylindrical surface, a spherical surface or a non-spherical surface, so that the Lambertian distributed light can be narrowed, diffused or unchanged to different degrees in the first thick-wall member 210 after passing through the first light entrance surface 214.
[0059] Similarly, the second light exit surface 223 is a smooth plane or a plurality of continuously arranged convex surfaces, which can be composed of corn grain patterns or diffusion patterns composed of regularly arranged strips, rectangles or hexagons, or can be a smooth surface without diffusion patterns.
[0060] In addition, the upper surface of the second thick-walled part 220 can be a smooth plane, and the lower surface can be a diamond pattern surface or other irregularly shaped reflective surface. The second optical channel 222 is composed of one or more surfaces with sparkling patterns. The bottom surface, top surface and side wall can be smooth surfaces, or the bottom surface, top surface and side wall can all be surfaces with sparkling patterns. The specific selection can be adapted according to the actual optical effect needs.
[0061] In a specific embodiment, as shown in the structural schematic diagram of the bifocal automobile signal light optical system, the light source 100 includes a first light source 110 and a second light source 120 of two different colors. Figure 3
[0062] In one form, the centers of the first light source 110 and the second light source 120 are located at the focal point position and the defocus position of the reflective surface 213, respectively. The light emitted by the light source at the focal point position can form a relatively concentrated light beam after focusing and reflecting by the optical system, with high light intensity and relatively regular light propagation direction, which usually propagates along the main optical axis of the optical system. The light emitted by the light source at the defocus position will appear to be divergent in the propagation process due to the deviation from the focal point of the optical system, with relatively low light intensity and more dispersed light distribution, forming a wider light beam angle and covering a larger area.
[0063] In another form, the centers of the first light source 110 and the second light source 120 are both located at the defocus position of the reflective surface 213. When both light sources are at the defocus position, the emitted light will appear to be divergent to some extent. In this case, the distribution of light in space will be more uniform, covering a larger area and being able to illuminate a larger area. At the same time, due to the divergence of light, different colored light will have more overlap and mixing in space, which helps to achieve better light mixing effect.
[0064] In a specific embodiment, a group of light sources 100 and reflective surfaces 213 form an entrance light unit, and the light sources 100 and the reflective surfaces 213 are one-to-one corresponding groups, and the groups of entrance light units are arranged in sequence.
[0065] The groups of light sources 100 can be located on the same PCB board, or can be located on different PCB boards according to other needs.
[0066] As shown in Figure 4 and Figure 5 As shown, the first pattern surface 211 and the second pattern surface 212 are not in the same plane. The second light-incident surface is arranged in parallel with the first light-emitting surface. This design is easier to realize the light emission of two different functional areas according to the preset route. In order to reasonably design the light effect, the area of the second pattern surface 212 is usually set to be greater than the area of the first pattern surface 211, for example, Figure 1 As shown, the height of the second pattern surface 212 is three to six times the height of the first pattern surface 211, so that most of the light is used to meet the light intensity and light type requirements of the regulations, and a small part of the light is used to form the sparkling lighting effect.
[0067] The upper and lower surfaces of the first optical channel 215 of the first thick-walled part 210 are parallel to each other, or the included angle of the upper and lower surfaces of the first optical channel 215 of the first thick-walled part 210 can be designed to be not greater than 5° according to other needs.
[0068] In specific embodiments, the second light-emitting surface is entirely composed of the first pattern surface 211 and the second pattern surface 212, forming an entire continuous light-emitting pattern surface. The longitudinal height of the reflecting surface 213 is consistent with the longitudinal height of the light-emitting pattern surface on the first light-emitting surface; or the longitudinal height of the reflecting surface 213 can be designed to be not less than 70% of the longitudinal height of the light-emitting pattern surface on the first light-emitting surface, and the longitudinal height of the reflecting surface 213 is not greater than 130% of the longitudinal height of the light-emitting pattern surface on the first light-emitting surface according to other needs. Thus, the incident light is maximally reflected to the second light-emitting surface.
[0069] The automobile signal lamp optical system provided by the present scheme ensures the overall light efficiency of the optical system without changing the light-emitting surface and the light-incident surface of the existing optical system, so as to meet the regulatory requirements. The design is to design the pattern surface with sparkling effect on the lower surface of the optical system, so as to have a diamond-like sparkling effect under natural light and after lighting. At the same time, a special optical pattern surface is designed on the light-emitting surface of the first thick-walled part 210, which is used to guide the incident light to the lower surface of the second thick-walled part 220, so as to enhance the lighting effect of the sparkling pattern surface.
[0070] In addition, the utility model also provides a vehicle, including the automobile signal lamp optical system in above-mentioned specific embodiments. The automobile signal lamp optical system can be applied to the vehicle, of course, can also be applied to the ship glass, aircraft glass or curtain wall environment. The automobile signal lamp optical system can be the signal lamp arranged in the front, rear or side of the vehicle.
[0071] Obviously, the vehicle containing the above automobile signal lamp optical system has the same beneficial effects, which will not be repeated here.
