[0049] Combination Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the structure of another lighting module provided in an embodiment of the present application. Figure 5A schematic diagram of a setting pattern provided in an embodiment of the present application. The light guiding device 200 provided in an embodiment of the present application includes a reflector 210, and a reflective surface 211 of the reflector 210 is arranged on the optical path of the outgoing light; the multiple microstructures are multiple microstructure reflective surfaces 211a formed by the reflective surface 211 of the reflector 210, wherein the multiple microstructure reflective surfaces 211a constitute the setting pattern, and the multiple microstructure reflective surfaces 211a collimate and reflect the outgoing light to form the dark area pattern S2. It can be understood that the reflective surface 211 of the reflector 210 provided in an embodiment of the present application is formed with multiple microstructure reflective surfaces 211a, and the multiple microstructure reflective surfaces 211a constitute the setting pattern. When the outgoing light of the light source device 100 is irradiated onto the reflective surface 211 of the reflector 210, the reflective surface 211 of the reflector 210 reflects the outgoing light into the target light spot S1. Moreover, due to the presence of the microstructure reflective surface 211a, the microstructure reflective surface 211a collimates the outgoing light of the light source device 100, adjusts the angle of the outgoing light corresponding to the target light spot S1, and forms a dark area on the target light spot S1. Thus, the outgoing light is collimated by all the microstructure reflective surfaces 211a, and a dark area pattern S2 is obtained on the target light spot S1. Figure 5 The X-shaped setting pattern composed of all the microstructure reflection surfaces 211a shown in FIG. 1 is formed. After the outgoing light of the light source device 100 is reflected by the reflection surface 211 having the X-shaped setting pattern, the following is obtained: Figure 3 The target light spot S1 shown has an X-shaped dark area pattern S2.
[0050] In some embodiments, when the plurality of microstructures provided in the embodiments of the present application are a plurality of microstructure reflective surfaces 211a formed by the reflective surface 211 of the reflector 210, the set pattern formed by all the microstructure reflective surfaces 211a may also be a pattern of other shapes. Figure 6 and Figure 7 As shown, Figure 6 A schematic diagram of another setting pattern provided in an embodiment of the present application, Figure 7 Schematic diagram of another target light spot provided in an embodiment of the present application, wherein the setting pattern composed of all microstructured reflection surfaces 211a on the reflection surface 211 of the reflector 210 provided in an embodiment of the present application can also be in the shape of a smiley face, and after the outgoing light of the light source device 100 is reflected by the reflection surface 211 having the setting pattern in the shape of a smiley face, the following is obtained: Figure 7 The target light spot S1 shown has a dark area pattern S2 in the shape of a smiley face.
[0051] Further, when a plurality of microstructured reflective surfaces 211a are formed on the reflective surface 211 of the reflector 210 provided in the embodiment of the present application, a lens 220 may be further provided on the optical path of the reflector 210 provided in the embodiment of the present application. Figure 8 As shown, it is a structural schematic diagram of another lighting module provided by an embodiment of the present application, wherein the light guiding device 200 provided by the embodiment of the present application includes a reflector 210, and the reflective surface 211 of the reflector 210 is arranged on the optical path of the outgoing light; the multiple microstructures are multiple microstructure reflective surfaces 211a formed by the reflective surface 211 arranged on the reflector 210, wherein the multiple microstructure reflective surfaces 211a constitute the set pattern, and the multiple microstructure reflective surfaces 211a collimate and reflect the outgoing light to form the dark area pattern S2. In addition, the light guiding device 200 provided by the embodiment of the present application also includes a lens 220 arranged on the optical path of the reflector 210. It can be understood that in the light guiding device 200 provided by the embodiment of the present application, a lens 220 is arranged on the optical path of the reflector 210, which can improve the lighting intensity of the lighting module and reduce the astigmatism of the lighting module. When the lighting module provided in the embodiment of the present application is used in a car lamp, the focusing ability of the lens 220 can make the light evenly illuminate the road surface, which not only improves the clarity of the lighting, but also can enhance the penetration in rainy and foggy weather, thereby improving the safety of vehicle driving; and the use of the lens 200 can also focus the light and reduce astigmatism, thereby avoiding the interference of dazzling light to oncoming vehicles when the car lamp is illuminated, further improving the safety of vehicle driving.
[0052] The multiple microstructures provided in the embodiments of the present application can be formed on the reflective surface of the reflector as well as on the surface of the lens.

Fig.10 A schematic diagram of another setting pattern provided in an embodiment of the present application, Fig.11A schematic diagram of another target light spot provided in an embodiment of the present application, wherein the light guiding device provided in the embodiment of the present application includes a reflector 230 and a lens 240, wherein the reflective surface 231 of the reflector 230 is arranged on the light path of the outgoing light, and the lens 240 is arranged on the light path of the reflector 230; the multiple microstructures are multiple microstructure light-transmitting surfaces 241 formed on the surface of the lens 240, wherein the multiple microstructure light-transmitting surfaces 241 constitute the set pattern, and the multiple microstructure light-transmitting surfaces 241 collimate and transmit the outgoing light reflected by the reflector 230 to form the dark area pattern S2. It can be understood that the surface of the lens 240 provided in the embodiment of the present application is formed with multiple microstructure light-transmitting surfaces 241, and when the outgoing light of the light source device 100 is reflected by the reflector 230 and incident on the lens 240, the lens 240 emits the outgoing light as the target light spot S1. Furthermore, since the lens 240 has a microstructured light-transmitting surface 241, the microstructured light-transmitting surface 241 collimates the outgoing light of the light source device 100, and adjusts the angle of the outgoing light corresponding to the target light spot S1, so that the outgoing light forms a dark area on the target light spot S1. Thus, the outgoing light is collimated by all the microstructured light-transmitting surfaces 241, and a dark area pattern S2 is obtained on the target light spot S1. Fig.10 The W-shaped setting pattern composed of all the microstructure light-transmitting surfaces 241 shown in FIG. 1 is obtained after the outgoing light of the light source device 100 is emitted through the lens 240 having the W-shaped setting pattern. Fig.11 The target light spot S1 shown has a W-shaped dark area pattern S2.
[0053] In one embodiment of the present application, when the lens 240 provided in the embodiment of the present application has a microstructure light-transmitting surface 241, the lens 240 can be arranged on the optical path of the reflector 230, thereby enhancing the illumination brightness of the illumination module and increasing the illumination distance of the illumination module. In addition, when the lens 240 provided in the embodiment of the present application has a microstructure light-transmitting surface 241, it can also be used alone to directly receive the emitted light of the light source device 100. For specific reference Fig.12As shown, it is a structural schematic diagram of another lighting module provided by an embodiment of the present application, wherein the light guiding device 200 provided by the embodiment of the present application includes a lens 240, and the lens 240 is arranged on the optical path of the outgoing light; the multiple microstructures are multiple microstructure light-transmitting surfaces 241 formed on the surface of the lens 240, wherein the multiple microstructure light-transmitting surfaces 241 constitute the set pattern, and the multiple microstructure light-transmitting surfaces 241 collimate and transmit the outgoing light to form the dark area pattern S2. It can be understood that the surface of the lens 240 provided by the embodiment of the present application is formed with multiple microstructure light-transmitting surfaces 241, and when the light source device 100 provides outgoing light, the outgoing light is directly incident on the lens 240, and the lens 240 emits the outgoing light as the target light spot S1. Furthermore, since the lens 240 has a microstructured light-transmitting surface 241, the microstructured light-transmitting surface 241 will collimate the outgoing light of the light source device 100, and adjust the angle of the outgoing light corresponding to the target light spot S1, so that the outgoing light forms a dark area on the target light spot S1. Thus, the outgoing light is collimated by all the microstructured light-transmitting surfaces 241, and a dark area pattern S2 is obtained on the target light spot S1.
