[0002] The present application relates to the technical field of vehicle lamps, and in particular to a daytime running light device, a headlight system and a vehicle. Background Art

[0003] Daytime running lights are often installed on the front of vehicles. Turning them on during the day isn't about helping the driver see the road clearly, but rather alerting others to approaching vehicles. This improves vehicle visibility and helps reduce the likelihood of accidents.

[0004] The primary purpose of DRLs is to make a vehicle more easily visible during daytime driving, primarily serving as a signal. However, due to their highly visible nature, manufacturers seek to enhance the vehicle's distinctive features, and consumers and drivers are also particularly interested in the lighting effects of DRLs.

[0005] For example, we hope that the daytime running light device can have a diamond lighting effect. Summary of the Invention

[0006] Based on this, it is necessary to provide a daytime running light device, a headlight system and a vehicle to address at least one of the above problems.

[0007] In a first aspect, the present application provides a daytime running light device, which includes: a first light-guiding device, including a first light-entering portion, a reflecting surface, and a first refractive surface sequentially arranged along a light path, the first refractive surface including a plurality of first refractive light-emitting surfaces that are deflected and spliced together; and a second light-guiding device, arranged on the light-emitting side of the first refractive surface, the second light-guiding device including a second light-entering portion and a second refractive surface sequentially arranged along the light path, the second refractive surface including a plurality of second refractive light-emitting surfaces that are deflected and spliced together.

[0008] By setting the first refractive surface and the second refractive surface, the daytime running light device can achieve a diamond lighting effect.

[0009] In some embodiments, the area of each of at least some of the second refracting light output surfaces is larger than the area of each of at least some of the first refracting light output surfaces. Exemplarily, the deviation angle of two adjacent second refracting light output surfaces is larger than the deviation angle of two adjacent first refracting light output surfaces.

[0010] With this arrangement, the first refractive surface is mainly used to cut the light beam, and the second refractive surface is mainly used to ensure the light output effect of the daytime running light device; in addition, the first refractive surface and the second refractive surface realize a complex diamond light effect.

[0011] In some embodiments, the first light guide device and the second light guide device are arranged sequentially along the first direction; the number of the first refractive light output surfaces is greater than 100, and the area of each first refractive light output surface is less than 2% of the projected area of the first refractive light output surface along the first direction. Exemplarily, the number of the second refractive light output surfaces is greater than 30, and the area of each second refractive light output surface is less than 10% of the projected area of the second refractive light output surface along the first direction.

[0012] With this arrangement, the light emitted from the first refractive surface has a fragmented light path. The daytime running light device can achieve a more layered lighting effect, with the light spots being split or overlapping.

[0013] In some embodiments, the first light guiding device and the second light guiding device are arranged in sequence along the first direction; multiple first refractive light output surfaces are spliced into a polyhedron structure; the second light input portion has a groove covering the first refractive surface, and the bottom surface of the groove of the second light input portion is opposite to the inclination direction of the second refractive surface relative to the first direction.

[0014] With such an arrangement, the polyhedron structure realizes a diamond light effect; is conducive to the second light entrance portion collecting light; and is conducive to the second light guide device effectively organizing light to avoid direct transmission of light.

[0015] In some embodiments, the daytime running light device further includes a plurality of first daytime running light light sources arranged along the second direction. The first daytime running light light sources face the corresponding first light incident portions along a third direction perpendicular to the second direction. Exemplarily, the first light incident portions are raised structures having a central hole. The reflective surface includes a plurality of sawtooth-shaped reflective tooth surfaces arranged along the second direction. Both the first and second refractive light output surfaces are flat surfaces.

[0016] This arrangement facilitates placement of the first DRL light source and facilitates a thinner, longer configuration. The first light inlet effectively collects light, reducing stray light and increasing light intensity. The reflective surface effectively diffuses and evens out light.

[0017] In some embodiments, the daytime running light device also includes a collimating lens and a third light guiding device; the third light guiding device is arranged on the light output side of the collimating lens, and the third light guiding device includes a third light input portion and a light output portion, the third light input portion includes a concave leather texture, and the light output portion includes a convex corn grain texture; the light output portion is located at the end of the second refractive surface.

[0018] With this arrangement, the daytime running light device can provide sufficient light in the direction of specific requirements using the collimating lens; and a more uniform granular light effect is achieved using the third light guide device, which can complement the overall effect of the diamond light effect.

[0019] In a second aspect, the present application provides a headlight system, which includes the aforementioned daytime running light device.

[0020] With this arrangement, the headlight system can utilize the daytime running light device for illumination, and can achieve a diamond lighting effect.

[0021] In some embodiments, the headlight system further includes a vertical daytime running light device; the headlight system includes two daytime running light devices arranged on both sides of the vertical daytime running light device, and the positions of the vertical daytime running light devices are offset relative to the daytime running light device.

[0022] With this arrangement, the headlight system provides sufficient daytime running light intensity, helping to ensure that the light distribution meets automotive industry regulations. The distribution of each device is easy to install and coordinate with other devices.

[0023] In some embodiments, the vertical daytime running light device includes a collimating lens and a third light guiding device; the third light guiding device is arranged on the light output side of the collimating lens, and the third light guiding device includes a third light input portion and a light output portion, the third light input portion includes a concave leather texture, and the light output portion includes a convex corn grain texture.

[0024] With this arrangement, the collimating lens is used to collect light, ensuring the overall light path direction and light intensity of the vertical daytime running light device; the leather texture helps to increase the diffusion angle and improve uniformity; the corn grain texture is conducive to ensuring the output effect and also helps to meet automotive industry regulations.

[0025] In some embodiments, the headlight system further includes a heat sink and a plurality of sequentially arranged second daytime running light sources. The heat sink is disposed on the backlight side of the second daytime running light sources, and the second daytime running light sources are disposed on the light-entering side of the collimating lens. Exemplarily, the light-entering curved surface of the collimating lens is convex, and the light-exiting curved surface of the collimating lens is convex. The unit structure of a leather grain is smaller than that of a corn grain pattern. The leather grain comprises multiple columns of unit structures, with adjacent columns of unit structures exhibiting undulations. A corn grain pattern comprises multiple rows of unit structures, with alternate rows of unit structures protruding from other rows.

[0026] Such a setting helps to ensure that the second daytime running light source provides sufficient light; the light of the vertical daytime running light device has a granular feel; and the light effect of the vertical daytime running light device can be harmoniously matched with the light effect of the daytime running light device.

[0027] In a third aspect, the present application also provides a vehicle, which includes the aforementioned headlight system.

[0050] refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 FIG2 is a partial structural diagram of a headlight system in an embodiment of the present application. The headlight system 1000 may include at least one of a first lens module 1200 , a second lens module 1300 , a vertical daytime running light device 1600 , and a starry sky light device 1700 .

[0051] For ease of description, a spatial rectangular coordinate system XYZ is established, where the X-axis direction is considered the front-to-back direction and can be roughly parallel to the first direction; the Y-axis direction is considered the left-to-right direction or the horizontal direction and can be roughly parallel to the second direction; and the Z-axis direction is considered the up-down direction or the vertical direction and can be roughly parallel to the third direction. The first lens module 1200 and the second lens module 1300 are each used to transmit light toward the front of the headlight.

[0052] In an exemplary embodiment, a headlight system 1000 according to an embodiment of the present application includes a daytime running light device 1500, which can be disposed within a mounting member 1. Headlight system 1000 can include two daytime running light devices 1500. Along the Z-axis, a first daytime running light device, a first lens module 1200, a second daytime running light device, and a second lens module 1300 can be sequentially disposed. Daytime running light devices 1500 can transmit light generally forward.

[0053] refer to Figure 4 The headlight system 1000 provided in the embodiment of the present application further includes a light-transmitting lampshade 1010. There may be two or more lampshades 1010. For example, the upper lampshade 1010 is used to cover the first lens module 1200 and transmit light, and the lower lampshade 1010 is used to cover the second lens module 1300 and transmit light.

[0054] The upper lampshade 1010 can cover the first lens module 1200 and the upper and lower daytime running light devices 1500 .

[0055] refer to Figure 2 The headlight system 1000 may further include a housing 1030 , which may be positioned between the mounting member 1 and the lampshade 1010 . The housing 1030 may have a channel corresponding to the first lens module 1200 . The inner wall of the channel may be flared and may be provided with a scattering layer. The housing 1030 may be compatible with the starry sky lamp device 1700 and the vertical daytime running lamp device 1600 .

[0056] The upper daytime running light device 1500 and the lower daytime running light device 1500 can be respectively matched with the cover 1030.

[0057] refer to Figures 5 to 8 The daytime running light device 1500 provided in the embodiment of the present application may include a first daytime running light light source 1501. The first daytime running light light source 1501 can emit light, for example, emit light upward.

[0058] The DRL device 1500 provided in the embodiments of the present application may include a first light guide 710. The first light guide 710 is used to transmit light forward. The first light guide 710 can be positioned above the first DRL light source 1501 along the Z-axis, allowing light to enter the first light guide 710. The compact structure facilitates electrical connection.

[0059] The first light guide device 710 may include a first light entrance portion 713, through which light emitted by the first daytime running light light source 1501 may enter the first light guide device 710. The first light guide device 710 has a certain length along the Y-axis direction. Multiple first daytime running light light sources 1501 and multiple first light entrance portions 713 may be provided along the Y-axis direction. The first light entrance portion 713 may be a raised structure with a central hole. Figure 8 and Figure 7 The surface of the raised structure is roughly a convex curve in a cross section parallel to the XZ plane, which helps to focus the light beam. The central hole helps to reduce reflections and thus reduce stray light.

[0060] The plurality of first daytime running light sources 1501 and the plurality of first light incident portions 713 may face each other along the third direction in a one-to-one correspondence. The first daytime running light light sources 1501 may face the center hole of the first light incident portion 713, or there may be a certain installation tolerance.

[0061] For example, the first light guide device 710 may include a reflective surface 711. The light transmitted by the first light incident portion 713 may be transmitted toward the reflective surface 711. The reflective surface 711 may achieve total internal reflection. Figure 5 and Figure 6 The reflective surface 711 may include a plurality of sawtooth-shaped reflective tooth surfaces. The light reflected by the reflective tooth surfaces may be deflected relative to the X-axis direction.

[0062] refer to Figure 5 and Figure 6 , multiple reflective tooth surfaces are arranged in sequence along the Y axis direction, and may also have a certain curvature, and the connection between the multiple reflective tooth surfaces in the cross section parallel to the XY plane is a sawtooth shape. Figure 8 The reflective tooth surface, in a cross-section parallel to the XZ plane, can be tilted at approximately 45° relative to the X-axis, reflecting light roughly along the Z-axis to reflect light along the XY plane. The reflective tooth surface can be smooth overall and may also include multiple vertical stripes. Multiple reflective tooth surfaces help diffuse light.

[0063] refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The first light guide device 710 may have a first refractive surface 712, which serves as a light-emitting surface of the first light guide device 710. The first refractive surface 712 includes a plurality of first refractive light-emitting surfaces 7121 that are mutually deflected and spliced. Different first refractive light-emitting surfaces 7121 have different normal directions, thereby forming micro-light beams with different refraction directions.

[0064] For example, the number of first refractive light output surfaces 7121 is greater than 100. The area of each first refractive light output surface 7121 may be less than 2% of the projected area of the first refractive surface 712 along the X-axis. The first refractive light output surface 7121 may be a plane. The first refractive light output surface 7121 may be a polygon, with the boundary between two adjacent first refractive light output surfaces 7121 being a straight line, which helps form micro-beams with sharp edges.

[0065] refer to Figure 6 For example, several first refractive light-emitting surface 7121 are spliced into a polyhedron structure. The polyhedron structure can be a flat-top structure or a pointed-top structure. The first refractive surface 712 can be composed of multiple polyhedron structures based on a common base, and adjacent polyhedron structures can be separated by a gap. The polyhedron structure can be smaller than one to four reflective tooth facets. The polyhedron structure can be less than 5% of the projected area of the first refractive surface 712 along the X-axis. The polyhedron structure can refract light to create a diamond effect.

[0066] For example, the first light guide device 710 can be a one-piece thick-walled part. The material of the first light guide device 710 can be transparent plastic and manufactured by injection molding or other methods. The polyhedron structure can be a convex polyhedron to ensure smooth demolding and also facilitate light extraction. The first light guide device 710 can be a flat structure along the XY plane.

[0067] The daytime running light device 1500 can achieve a diamond lighting effect. The light emitted from the first refractive surface 712 has a fragmented light path.

[0068] The daytime running light device 1500 may further include a second light guide device 720. The second light guide device 720 may be disposed in front of the first light guide device 710 along the X-axis direction for transmitting light. Figure 5 The second light guide device 720 may include a connecting plate 722, and the connecting plate 722 is connected to the first light guide device 710. The second light guide device 720 may be fixed to the first light guide device 710, and the two may be connected and positioned by pins.

[0069] refer to Figure 8 The second light guide device 720 may include a second light entrance portion 723. The second light entrance portion 723 may have a groove covering the first refractive surface 712 to facilitate light collection. Light received at the second light entrance portion 723 can be transmitted to the second refractive surface 721 of the second light guide device 720.

[0070] Exemplarily, the second light guide 720 is a one-piece thick-walled member, also generally having a flat structure based on the XY plane. Along the Z-axis, the second light entrance portion 723 is thicker than the first refractive surface 712. Furthermore, the majority of the second light guide 720 structure can be substantially the same thickness as the second refractive surface 721 and can be thinner than the second light entrance portion 723. The second light entrance portion 723 can extend downward from the main body of the second light guide 720. The majority of the second light guide 720 structure can be thinner than the first light guide 710.

[0071] The DRL device 1500 of the embodiment of the present application is relatively thin. The DRL device 1500 may include a first circuit board 1020. A first DRL light source 1501 may be disposed on the first circuit board 1020. The first circuit board 1020 is disposed substantially along an XY plane.

[0072] The second light entrance portion 723 is located on the light-emitting side of the first refractive surface 712. The groove-shaped second light entrance portion 723 can cover the first refractive surface 712. The second light entrance portion 723 can substantially cover the polyhedron structure. The connecting plate 722 can be connected to the second light entrance portion 723.

[0073] Exemplarily, the groove bottom surface 7231 of the second light input portion 723 is opposite to the inclination direction of the second refractive surface 721 relative to the first direction. The groove bottom surface 7231 faces the first refractive surface 712 and is inclined upward. The second refractive surface 721 faces away from the groove bottom surface 7231, and the second refractive surface 721 is turned downward facing one side of the light path, that is, one side of the outgoing light path can be upward. The light beam emitted by the first refractive surface 712 is directed in various directions, passes through the second light input portion 723, enters the second light guiding device 720, and is then emitted from the second refractive surface 721. The second light input portion 723 and the second refractive surface 721 are not arranged in parallel, which helps the second light guiding device 720 to effectively organize the light and ensure that the second light guiding device 720 functions properly.

[0074] The second refractive surface 721 serves as the light-emitting surface of the second light-guiding device 720. The second refractive surface 721 may include multiple second refractive light-emitting surfaces 7211 that are mutually deflected and spliced. The normals of different second refractive light-emitting surfaces 7211 differ in direction. The micro-light beams passing through the second refractive light-emitting surfaces 7211 are already oriented in various directions. These second refractive light-emitting surfaces 7211 can further refract the light, forming beams with different diamond-like light effects.

[0075] Exemplarily, the number of second refractive light output surfaces 7211 is greater than 30. The area of each second refractive light output surface 7211 may be less than 10% of the projected area of the second refractive surface 721 along the X-axis. The second refractive light output surface 7211 may be a plane. The area of the second refractive light output surface 7211 may be greater than the area of the first refractive light output surface 7121. The deflection angle between two adjacent second refractive light output surfaces 7211 may be greater than the deflection angle between two adjacent first refractive light output surfaces 7121.

[0076] refer to Figure 5 and Figure 7 , multiple second refractive light surfaces 7211 are spliced to form a continuous grain structure. The boundary between two adjacent second refractive light surfaces 7211 can be a straight line. The second refractive light surface 7211 can be a polygon. The entire second refractive surface 721 can be roughly a convex polyhedron protruding forward. The deviation angle of two adjacent second refractive light surfaces 7211 can be an obtuse angle, and each second refractive light surface 7211 has a relatively small deviation; while the deviation angle of the first refractive light surface 7121 can be close to a right angle, and the side wall of the polyhedron structure can be almost perpendicular to the YZ plane.

[0077] The daytime running light device 1500 can achieve a more layered lighting effect, with light spots that can be separated or overlapped. The daytime running light device 1500 can also create a complex diamond light effect. The headlight system 1000 can also achieve a diamond light effect.

[0078] In some embodiments, the daytime running light device 1500 may be considered to include two first light guide devices 710 and two second light guide devices 720, one first light guide device 710 and a corresponding second light guide device 720 may be located at the upper part, and another first light guide device 710 and a corresponding second light guide device 720 may be located at the lower part.

[0079] refer to Figure 11 The daytime running light device 1500 may include a collimating lens 8 and a third light guide 9. The third light guide 9 is disposed on the light-exiting side of the collimating lens 8. The third light guide 9 includes a third light entrance portion 91 and a light exit portion 92. The third light entrance portion 91 corresponds to the collimating lens 8. The third light entrance portion 91 may include a concave leather grain, and the light exit portion 92 may include a convex corn grain.

[0080] Based on the X-axis, the daytime running light device 1500 may include additional light sources located on the light-entering side of the collimating lens 8. The light-emitting portion 92 of the third light guide 9 may roughly correspond to the second refractive surface 721 of the second light guide 720. The light-emitting end of the daytime running light device 1500 may have an overall shape depending on the installation location or the components it is used with. Along the Z-axis, the third light guide 9 may be located between the two second light guides 720. For example, along the Y-axis, the third light guide 9 may be offset relative to the middle of the second light guides 720. The light-emitting portion 92 may be located at the end of the second refractive surface 721. Specifically, in a left headlight, the end of the second refractive surface 721 may be the left end; in a right headlight, the end of the second refractive surface 721 may be the right end. The third light guide 9 and the second light guide 720 may form a zigzag shape. The third light guide 9 and the two second light guides 720 may form a zigzag shape.

[0081] refer to Figure 9 、 Figure 10、 Figure 11 and Figure 12 The headlight system 1000 includes a vertical daytime running light device 1600 . In an exemplary embodiment, the vertical daytime running light device 1600 includes a collimating lens 8 and a third light guide device 9 .

[0082] refer to Figure 11 For example, the light incident curved surface 801 of the collimating lens 8 is a convex surface, and the light emitting curved surface 802 of the collimating lens 8 is a convex surface. The collimating lens 8 is used to collect light to ensure the direction and intensity of the overall outgoing light path of the vertical daytime running light device 1600.

[0083] The third light guide device 9 is provided on the light exiting side of the collimating lens 8, and the third light guide device 9 includes a third light incident portion 91 and a light exit portion 92. Figure 12 The third light incident portion 91 includes concave grains, which help increase the diffusion angle and improve uniformity. Figure 10 The light-emitting portion 92 includes raised corn-grain patterns, which are beneficial to ensuring the emission effect.

[0084] Exemplarily, the headlight system 1000 includes multiple second DRL light sources 1601. Specifically, the vertical DRL device 1600 includes multiple second DRL light sources 1601 arranged sequentially along the Z-axis. Multiple collimating lenses 8 can be provided in a one-to-one correspondence with the multiple second DRL light sources 1601, providing sufficient light intensity.
