[0033] The following will be combined with the accompanying drawings to clearly and completely describe the embodiments of this application. Obviously, the described embodiments are only embodiments of one area of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0035] As described in the background technology section, traditional technologies such as concentrators or reflectors are currently commonly used to implement autonomous driving marker lights, resulting in unsatisfactory lighting effects of the autonomous driving marker lights.
[0036] Specifically, with the development and increasing popularity of intelligent assisted driving, more and more vehicles are equipped with these systems. To accommodate different vehicles, the design of autonomous driving marker lights is becoming increasingly diverse. However, related technologies typically use traditional solutions such as concentrators or reflectors to achieve autonomous driving markers. These solutions are not suitable for headlights with large luminous areas and steeply curved surfaces, resulting in light streaks and uneven lighting.
[0037] Based on the above, this application provides an automatic driving marker light, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an autonomous driving marker light provided in this application, which includes:
[0038] The light source 100 is used to emit an indicator light beam, which can illuminate the automatic driving marker light.
[0039] Light guide plate 200, such as Figure 2 As shown, the light source 100 is disposed on the light incident surface 210 of the light guide plate 200 , and the indicator light beam emitted by the light source 100 enters the light guide plate 200 through the light incident surface 210 of the light guide plate 100 .
[0040] The lampshade 300 has the same shape as that of the light guide plate 200 and covers the light emitting surface 220 of the light guide plate 200. The indication light beam emitted by the light source 100 is emitted from the lampshade 300 through the light emitting surface 220 of the light guide plate 200. That is, the indication light beam emitted by the light source 100 enters the light guide plate 200 through the light incident surface 210 of the light guide plate 200, is transmitted in the light guide plate 200, and then is emitted from the light emitting surface 220 of the light guide plate 200, and finally is emitted from the lampshade 300.
[0041] The surface of the light guide plate 200 is a smooth surface, and the light incident surface 210 and the light emitting surface 220 of the light guide plate 200 are different surfaces of the light guide plate 200 .
[0042] Based on the above, the present application provides an autonomous driving marker light having a light guide plate 200 with a light entrance surface 210 and a light exit surface 220. The light source 100 is mounted on the light entrance surface 210 of the light guide plate 200, so that the indicator light beam emitted by the light source 100, after entering the light guide plate 200, can be emitted from the light guide plate 200 through the light exit surface 220 of the light guide plate 200, and finally emitted from the light shield 300 covering the light exit surface 220 of the light guide plate 200. Since the shape of the light shield 300 is the same as that of the light guide plate 200, for the autonomous driving marker light provided by the present application, the size of the light exit surface 220 of the light guide plate 200 is the light exit area of the autonomous driving marker light. In other words, the light exit area of the autonomous driving marker light is determined by the light exit surface of the light guide plate 200, so that the light exit area of the autonomous driving marker light can be made larger according to actual needs. In addition, the surface of the light guide plate 200 is a smooth surface. Therefore, due to the light uniforming effect of the light guide plate 200, the light output area of the autonomous driving marker light can be larger and it can also have a better uniform lighting effect. Compared with the existing technology, it can to a certain extent solve the problem of bright marks and uneven lighting effect when the luminous effect has a large area and a large-angle curved surface.
[0043] Based on the above embodiments, in one embodiment of the present application, the surface of the lampshade 300 has a preset pattern 301, for example Figure 3 As shown, the surface of the lampshade 300 has horizontal stripes. However, when the surface of the lampshade 300 has a preset pattern, the inconsistent thickness of the lampshade 300 will lead to uneven lighting, especially at locations where the thickness changes abruptly. In the present application, the lampshade 300 is a uniform light lampshade, that is, the lampshade 300 is made of a uniform light material. After the indicator light beam enters the uniform light lampshade, it will be diffusely scattered inside the uniform light lampshade. This can reduce the total internal reflection caused by the abrupt change in surface shape at locations where the thickness changes abruptly, such as the ridges of the horizontal stripes. This can effectively eliminate the bright spots on the luminous surface caused by various shapes such as horizontal stripes on the lampshade surface, thereby improving the lighting uniformity of the autonomous driving marker light.
[0044] In this embodiment, the light guide plate 200 is a PLEXIGLAS LD scattering light guide plate, and the specific model may be 8N LD48 or 8N LD96, but this application does not limit this, and the specific model depends on the situation.
[0045] Based on the aforementioned embodiments, in one embodiment of the present application, at least one area of the light emitting surface 220 of the above-mentioned light guide plate 200 is not in the same plane as other areas, that is, the light emitting surface of the light guide plate 200 can be a curved surface, so that the light emitting surface of the light guide plate 200 can be made into a corresponding shape based on actual conditions, can be adapted to more types of vehicles, and is more practical.
[0046] Based on the above embodiments, in one embodiment of the present application, Figure 4 As shown, the light emitting surface 220 of the light guide plate 200 includes a first area 221 and a second area 222. The first area 221 and the second area 222 are connected, and there is a preset angle A between the plane where the first area 221 is located and the plane where the second area 222 is located. The value range of the preset angle A is 0°~180°, excluding the endpoint value. That is to say, the light guide plate 200 can have a certain bending angle, so that the automatic driving indicator light can be made into a shape with a uniform lighting effect and a certain bending angle, which is more practical.
[0047] Based on the above embodiments, in one embodiment of the present application, Figure 5 As shown, the light guide plate 200 includes a first surface 201 and a second surface 202 surrounding the first surface 201. The first surface 201 is a light emitting surface 220 of the light guide plate 200, and the second surface 202 is a light incident surface 210 of the light guide plate 220. The light source 100 is disposed on at least a portion of the second surface 202. In other words, the light source 100 may be disposed on a portion of the second surface 202, or on the entire second surface 202. The specific configuration can be flexible based on actual conditions.
[0048] Based on the above embodiments, in one embodiment of the present application, Figure 5 As shown, the second surface 202 includes a third region 2021, a fourth region 2022, a fifth region 2023, and a sixth region 2024 arranged clockwise. The regions in the third region 2021 are located in the same plane, the regions in the fifth region 2023 are located in the same plane, a portion of the fourth region 2022 forms a predetermined angle A with the rest of the region, and a portion of the sixth region 2024 forms a predetermined angle A with the rest of the region. That is, the third region 2021 and the fifth region 2023 are located in the same plane, while the fourth region 2022 and the sixth region 2024 have a certain bending angle.
[0049] For example, the first surface 201, i.e., the light emitting surface 220, has a rectangular first region 221 and a second region 222. Then, the third region 2021 of the second surface 202 covers the side of the first region 221 facing away from the second region 222, the fifth region 2023 covers the side of the second region 222 facing away from the first region 221, the fourth region 2022 covers one side of the first region 221 and one side of the second region 222, and the sixth region 2024 covers one side of the first region 221 and one side of the second region 222. Based on the above, if the light guide plate 200 is regarded as a bent rectangle, the third region 2021 and the fifth region 2023 cover two opposite sides of the rectangular light guide plate, the fourth region 2022 and the sixth region 2024 cover the other opposite sides of the rectangular light guide plate, and the sides covered by the third region 2021 and the fifth region 2023 are not bent, while the sides covered by the fourth region 2022 and the sixth region 2024 are bent.
[0050] Preferably, the light source 100 is arranged in at least one of the third area 2021 and the fifth area 2023, that is, the light source 100 is arranged in the third area 2021, or the light source 100 is arranged in the fifth area 2023, or the light source 100 is arranged in the third area 2021 and the fifth area 2023.
[0051] Specifically, the light source 100 is arranged in at least one of the third area 2021 and the fifth area 2023, and the parts of the third area 2021 and the fifth area 2023 are in the same plane, so that the LED light beam in the light source 100 will only overlap with the adjacent LED light beam, and then if the light emission of the LED in the light source 100 is affected, it will only be affected by the adjacent LED. Therefore, through the arrangement of the LEDs in the light source 100, such as the spacing between the LEDs in the light source 100, the mutual influence between the LEDs is reduced, thereby further ensuring the lighting effect of the automatic driving indicator light.
[0052] Based on the above embodiments, in one embodiment of the present application, Figure 5 As shown, the light guide plate 200 further includes a third surface 203, which is opposite to the first surface 201 and serves as a light incident surface of the light guide plate 200. The light source 100 is disposed on the third surface 203. Specifically, the light source 100 can be disposed on the second surface 202, or on the third surface 203, or on both the second surface 202 and the third surface 203. This allows the location and number of the light sources 100 to be arranged based on actual needs, resulting in greater flexibility and practicality.
[0053] Based on the above embodiments, in one embodiment of the present application, Figure 6As shown, the automatic driving marker light also includes:
[0054] The first light shielding frame 410 covers the second surface 202 and prevents the indicator light beam emitted by the light source 100 from overflowing from the second surface 202 , so that more of the indicator light beam emitted by the light source 100 can be emitted from the light emitting surface 220 of the light guide plate 200 .
[0055] Based on the foregoing embodiment, in one embodiment of the present application, the automatic driving marker light further includes:
[0056] The second light shielding frame covers the third surface, and suppresses the indicator light beam emitted by the light source 100 from overflowing from the third surface 203 , so that more of the indicator light beam emitted by the light source 100 can be emitted from the light emitting surface 220 of the light guide plate 200 .
[0057] Accordingly, the present application also provides a vehicle lamp comprising the autonomous driving marker lamp described in any of the above embodiments. It should be noted that the autonomous driving marker lamp of the vehicle lamp is the autonomous driving marker lamp described in any of the above embodiments, and its specific structure has been described in detail in the above embodiments and will not be repeated here.
[0058] In summary, the present application provides an automatic driving marker light and a vehicle light, the automatic driving marker light comprising: a light source, a light guide plate and a lampshade. The light source is arranged on the light incident surface of the light guide plate, and the indicator light beam emitted by the light source enters the light guide plate through the light incident surface of the light guide plate. The shape of the lampshade is the same as that of the light guide, and covers the light exit surface of the light guide plate. The indicator light beam emitted by the light source is emitted from the lampshade through the light exit surface of the light guide plate, that is, after the indicator light beam emitted by the light source enters the light guide plate through the light incident surface of the light guide plate, it is transmitted in the light guide plate, then emitted from the light exit surface of the light guide plate, and finally emitted from the lampshade. The surface of the light guide plate is a smooth surface, and the light incident surface and the light exit surface of the light guide plate are different surfaces of the light guide plate. It can be seen from this that for the automatic driving marker light provided by the present application, the size of the light exit surface of the light guide plate is the light exit area of the automatic driving marker light, that is, the light exit area of the automatic driving marker light is determined by the light exit surface of the light guide plate, so that the light exit area of the automatic driving marker light can be made larger according to actual needs. In addition, the surface of the light guide plate is a smooth surface. Therefore, due to the light uniforming effect of the light guide plate, the light output area of the autonomous driving marker light can be larger and it can also have a better uniform lighting effect. Compared with the existing technology, it can to a certain extent solve the problem of bright marks and uneven lighting effect when the appearance of the shape has a large area and a large-angle curved surface.
