Technical Field
[0001] The invention relates to the technical field of light guide and light emitting technology, and in particular to an optical component and a vehicle lamp. Background Art
[0002] As a relatively common light-guiding technology, light guides have relatively large restrictions on their shape due to the limitations of their own light-emitting characteristics. For example, the more common light guide shapes are horizontal bars, vertical bars or arcs.

Many complex-shaped car light-emitting solutions are difficult to achieve with conventional light guides. If they are replaced with other optical light-emitting forms, the price advantage cannot be reflected.

Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0036] See also Figure 1 , Figure 1 The following is a schematic diagram showing a usage scenario of the optical component provided by an embodiment of the present invention. Figure 1 As shown, for a headlight with a complex shape of the transmission part 3 (such as a light guide cover), its light-emitting area is larger. It not only has a traditional main light-emitting area to meet the requirements of technical regulations on the lighting conditions of the headlight, but also a complex area adjacent to the main light-emitting area is set as an auxiliary light-emitting area. Since the auxiliary light-emitting area also needs to be lit, it is difficult to obtain a satisfactory lighting effect by using a traditional single light guide. If light guides are set in the main light-emitting area and the auxiliary light-emitting area respectively, the setting of multiple light guides also involves a structural change in the position of the light source, which will greatly increase the cost of the headlight and lose the market advantage.
[0037] See also Figure 2 to Figure 9 , Figure 2 The cross-sectional view shows the positional coordination relationship between adjacent components when the light guide system according to the embodiment of the present invention is suitable for installation scenarios of complex vehicle lamp shapes. Figure 3 Demonstrated based on Figure 2 The screenshot shows the matching relationship of the components and the light-emitting principle of the light guide system. Figure 4 The overall three-dimensional structure of the light guide 1 is shown. In order to more intuitively display the technical details of the light guide 1, Figure 5 Shown Figure 4 The local enlarged structure in Figure 6 It shows along Figure 5 The schematic diagram of the cross-sectional structure of the light guide 1 obtained by cutting the light guide 1 along the BB line. Figure 7 It shows along Figure 5 A schematic diagram of the cross-sectional structure of the auxiliary tooth 102a of the light guide 1 obtained by cutting the light guide 1 along the CC line. Figure 8 An example of the light propagation path at the position of the auxiliary tooth 102a in the light guide 1 is shown. Fig. 9 An example of a fisheye pattern reflective pattern 2b provided on the reflective surface 2a of the reflective plate 2 is shown.
[0038] like Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an optical component, including a light guide 1, a reflective plate 2 and a transmissive member 3, wherein the reflective plate 2 is arranged along the length direction of the light guide 1 and adjacent to the light guide 1, and the transmissive member 3 is arranged opposite to the reflective plate 2, a first part of the light emitted from the light guide 1 is directly emitted through the transmissive member 3 to form a first light emitting area, and a second part of the light emitted from the light guide 1 is reflected by the reflective plate 2 and then emitted through the transmissive member 3 to form a second light emitting area.
[0039] It is understandable that, based on the defects of the background technology, the optical component provided in this embodiment is suitable for the lighting scene of the headlight, especially for the headlight structure with complex shapes. Through a single light guide 1, a better lighting effect of the complex headlight can be achieved. During use, the light source is incident from one end of the light guide 1. Due to the principle of linear propagation of light, the first part of the incident light reaches the transmission part 3 after being transmitted by the light guide 1, and is emitted from the first light emitting area (main light emitting area) of the transmission part 3 to meet the requirements of the regulations on the lighting conditions of the headlight; the second part of the light is transmitted by the light guide 1 and emitted to the reflective plate 2, and then reflected by the reflective surface of the reflective plate 2, and then emitted from the second light emitting area (auxiliary light emitting area) of the transmission part 3. The optical component of this embodiment increases the light emitting area of the optical component through the cooperation of the main light emitting area and the auxiliary light emitting area, enhances the uniformity of the overall lighting of the light guide system, improves the lighting quality of the headlight, and meets the diverse needs of the headlight lighting under various shapes. The optical component of this embodiment can obtain excellent overall lighting effect of the headlight through only one light guide 1, with great cost advantages and strong market competitiveness.
[0040] Based on the above technical solution, the present invention can also be improved as follows.
[0041] In one possible implementation, Figures 4 to 6 As shown, a main reflection surface 101 and a main transmission surface 102 are provided on the cylindrical surface of the light guide 1, and the main reflection surface 101 and the main transmission surface 102 are arranged relative to the axis of the light guide 1, for example Figure 2 As shown in the perspective of FIG. 1 , the main reflection surface 101 is arranged on the left side of the light guide 1, the main transmission surface 102 is arranged on the right side of the light guide 1, and the central axis of the light guide 1 is located on the line connecting the central points of the main reflection surface 101 and the main transmission surface 102. Figure 5 As shown, if the axial direction of the light guide 1 is defined as the horizontal direction, the main reflection surface 101 is provided with a plurality of vertically arranged main teeth 101a, and the main teeth 101a have a flat, sawtooth or arc-shaped reflective surface. Since the main reflection surface 101 and the main transmission surface 102 are arranged opposite to each other with respect to the central axis of the light guide 1, the main teeth 101a reflect the first part of the light transmitted by the light guide 1 toward the main transmission surface 102. The main transmission surface 102 is a convex surface, and the main transmission surface 102 reflects the first part of the light transmitted by the light guide 1 toward the first light exit area (corresponding to the first light exit area of the transmission member 3) of the transmission member 3. Figure 1 In order to increase the light emitting area of the light guide system, the curvature of the main transmission surface 102 can be increased, for example, the curvature of the main transmission surface 102 is set to a semicircle or a major arc. The edge of the main transmission surface 102 is provided with a plurality of auxiliary teeth 102a, such as Figure 7 As shown in the cross-sectional structure of the auxiliary tooth 102a, the auxiliary tooth 102a can be configured as a protruding structure. Figure 8 As shown in the schematic diagram of the light propagation path, the auxiliary tooth 102a scatters the second part of the light propagated by the light guide 1 to the position of the auxiliary tooth 102a toward the reflector 2. Figure 3 Schematic diagram, due to the principle of rectilinear propagation of light, the reflector 2 directs the received second part of the light toward the second light emitting area (corresponding to the second light emitting area) of the transmission member 3. Figure 1 The auxiliary light-emitting area on the middle transmission member 3) is reflected, thereby lighting up the auxiliary light-emitting area of the vehicle lamp.
[0042] It can be understood that in this embodiment, the light source is incident from one end of the light guide 1. Due to the principle of linear propagation of light, most of the incident light is reflected by the main teeth 101a of the main reflection surface 101 and reaches the main transmission surface 102, and then passes through the first light emitting area of the transmission element 3 (corresponding to Figure 1 The incident light (second part of the light) is emitted from the main light emitting area of the transmission member 3 to meet the requirements of the regulations on the lighting conditions of the vehicle lamp; another part of the incident light (the second part of the light) is emitted through the convex surface of the auxiliary teeth 102a at the edge of the main transmission surface 102 and the edge of the main transmission surface 102, and then reflected by the reflection surface 2a of the reflection plate 2, and then emitted from the second light emitting area of the transmission member 3 (corresponding to the Figure 1In this embodiment, the auxiliary teeth 102a are arranged so that more light is guided to the reflector 2, thereby increasing the light intensity of the auxiliary light-emitting area, enhancing the uniformity of the overall light of the light guide system, improving the light quality of the headlight, and meeting the diverse needs of headlight illumination under various shapes.
[0043] In one possible implementation, Figure 2 and Figure 6 As shown, a first auxiliary reflection surface 103 and a second auxiliary reflection surface 104 are also provided on the cylindrical surface of the light guide 1, and the main reflection surface 101, the first auxiliary reflection surface 103, the main transmission surface 102 and the second auxiliary reflection surface 104 are connected end to end in sequence along the circumference of the light guide 1 to form a closed loop, and the first auxiliary reflection surface 103 and the second auxiliary reflection surface 104 reflect the first part of the light propagated by the light guide 1 toward the main transmission surface 102.
[0044] It can be understood that the functions of the first auxiliary reflection surface 103 and the second auxiliary reflection surface 104 are, first, to connect the main reflection surface 101 and the main transmission surface 102, and second, to reflect light, reflecting the first part of the light propagated by the light guide 1 toward the main transmission surface 102. However, due to the reflection angle problem, the first part of the light reflected by the first auxiliary reflection surface 103 and the second auxiliary reflection surface 104 is more toward the edge of the main transmission surface 102, thereby providing illumination light for the auxiliary light-emitting area.
[0045] In one possible implementation manner, the first auxiliary reflection surface 103 and the second auxiliary reflection surface 104 can be planes. In order to obtain a better luminous effect of the auxiliary light-emitting area, Figure 2 and Figure 6 As shown in the cross-sectional view of , the first auxiliary reflection surface 103 and the second auxiliary reflection surface 104 are set as concave surfaces that tend to be concave inwardly of the central axis of the light guide 1. Since the concave surface that tends to be inwardly of the light guide 1 has a better light scattering effect than the flat surface inside the light guide 1, this setting can increase the light intensity at the edge of the main transmission surface 102, thereby improving the brightness of the auxiliary light emitting area, and making the light intensity uniformity of the entire light guide system better.
[0046] In one possible implementation, please refer to Figure 6 as well as Figure 7 The cross-sectional diagrams at two different angles are shown in FIG. Figure 6 As shown, the length direction of each auxiliary tooth 102a is perpendicular to the axial direction of the light guide 1, and a plurality of auxiliary teeth 102a are arranged side by side along the axial direction of the light guide 1. The light at the edge of the main transmission surface 102 is guided to the reflection surface 2a of the reflection plate 2 by a plurality of auxiliary teeth 102a, thereby increasing the light intensity of the auxiliary light emitting area. Figure 2 , Figure 5 , Figure 6 As shown, the main teeth 101 a are arranged perpendicular to the axial direction of the light guide 1 , and a plurality of the main teeth 101 a are arranged side by side along the axial direction of the light guide 1 .
[0047] In one possible implementation manner, the auxiliary tooth 102a is an arc-shaped ridge structure, such as a sawtooth ridge or an arc-shaped ridge. Figure 7 As shown in the cross-sectional view, in this embodiment, the auxiliary tooth 102a is exemplified by an arc-shaped ridge (such as a semi-cylindrical ridge). Figure 8 The light propagation path at the auxiliary tooth 102a in the light guide 1 is shown. A part of the light propagating in the light guide 1 continues to propagate backward after being reflected, and another part of the light reaches the auxiliary tooth 102a, is emitted from the surface of the auxiliary tooth 102a, and reaches the reflector 2. The arc-shaped ridges make it easier for light to be emitted from the light guide 1 to the reflector 2. Figure 8 In the structure, the auxiliary tooth 102a adopts a semi-cylindrical convex ridge structure to intercept part of the light refracted inside the light guide 1, and then diffuses and transmits the collected light through the arc surface, which is used to increase the brightness of the auxiliary light-emitting area and reduce the brightness difference between the auxiliary light-emitting area and the main light-emitting area.
[0048] In one possible implementation, the main teeth 101a are arc-shaped grooves or sawtooth grooves that are recessed toward the main transmission surface 102 of the light guide 1 and have a light reflection function. Figure 5 As shown, in this embodiment, an arc-shaped groove is used as an example. The plurality of main teeth 101a arranged in a row diffusely reflect the light propagating in the light guide 1 toward the main transmission surface 102, so that the light propagates more evenly toward the main light-emitting area.
[0049] In one possible implementation, the main reflection surface 101 is parallel to the axial direction of the light guide 1, so that the light distribution in the main light-emitting area can be more uniform. For example, the main reflection surface 101 is set to be a plane parallel to the axial direction of the light guide 1. The plane has a better reflective effect, so that the light is evenly reflected from the main reflection surface 101 to the main transmission surface 102.
[0050] like Figure 2 and Figure 3 As shown, the reflecting surface 2a of the reflecting plate 2 is a concave curved surface, and the direction of the reflecting surface 2a of the reflecting plate 2 perpendicular to the axial direction of the light guide 1 conforms to the parabola rule.
[0051] It can be understood that the concave surface reflects the light transmitted from the edge of the light guide 1 and the auxiliary teeth 102a on the edge of the light guide 1 toward the auxiliary light-emitting area on the transmission member 3. Since the concave surface has a converging effect on light, the reflective plate 2 adopts a reflective surface 2a with a curvature close to a parabola, which can concentrate the reflected light on the preset auxiliary light-emitting area, thereby increasing the light intensity of the auxiliary light-emitting area, reducing the brightness difference between the auxiliary light-emitting area and the main light-emitting area, and improving the uniformity of the brightness of the car lamp.
[0052] like Fig. 9 As shown, the reflective surface 2a of the reflector 2 is provided with a plurality of reflective stripes 2b, preferably a fisheye pattern reflective stripe 2b. The reflective stripe 2b may be a convex type (e.g., a convex ridge structure) or a concave type (e.g., a reflective groove structure). The reflective surface 2a of the reflector 2 collects the light emitted from the auxiliary teeth 102a of the light guide 1 and the edge of the light guide 1, and then reflects through the parabolic reflective surface 2a and diffuses through the fisheye pattern reflective stripe 2b on the surface, so that the auxiliary light-emitting area of the headlight is illuminated, and the light-emitting uniformity reaches the optimal state.
[0053] In one possible embodiment, in order to improve the light propagation efficiency in the light guide 1, reduce losses, and improve the luminous brightness of the car lights, an anti-reflection and anti-reflection film can be set on the main transmission surface 102 and the auxiliary teeth 102a, and an anti-reflection and anti-reflection film layer can be set on the main reflection surface 101, the main teeth 101a, the first auxiliary reflection surface 103, the second auxiliary reflection surface 104 and the reflection surface 2a of the reflection plate 2.
[0054] Based on the optical components of the aforementioned embodiments, this embodiment further provides a vehicle lamp (not shown in the figures), which includes the optical components of the aforementioned embodiments.
[0055] The optical component and vehicle lamp provided by the present invention are suitable for vehicle lamp lighting scenes, especially for vehicle lamp structures with complex shapes. A single light guide 1 can achieve a better lighting effect of a complex vehicle lamp. During use, the light source is incident from one end of the light guide 1. Due to the principle of rectilinear propagation of light, most of the incident light (the first part of the light) is reflected by the main teeth 101a of the main reflection surface 101 and reaches the main transmission surface 102, and is emitted from the main light-emitting area of the light guide system to meet the requirements of the regulations on vehicle lamp illumination conditions; another part of the incident light (the second part of the light) is emitted through the convex surface of the auxiliary teeth 102a at the edge of the main transmission surface 102 and the edge of the main transmission surface 102, and then is reflected by the reflection surface 2a of the reflection plate 2, and is emitted from the auxiliary light-emitting area of the light guide system. The optical assembly of the present invention increases the light-emitting area of the light-guiding system by coordinating the main light-emitting area with the auxiliary light-emitting area; the auxiliary teeth 102a are arranged so that more light is guided to the reflector 2, thereby increasing the light intensity of the auxiliary light-emitting area, enhancing the uniformity of the overall light of the light-guiding system, improving the light-emitting quality of the headlight, and meeting the diverse needs of the headlight illumination under various shapes. The light-guiding system of this embodiment can obtain an excellent overall light-emitting effect of the headlight with only one light guide 1, with great cost advantages and strong market competitiveness.
[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
