It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.
[0042] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "provided with", "installed", "connected", and "arranged" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connection member, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0043] In the present utility model, in the following description, some directional words, such as "up", "down", "left", "right", etc., are involved in order to clearly explain the technical solution of the present application. Based on the normal use orientation of the signal light optical system, "front" refers to the direction indicated by the light emission direction, "rear" refers to the direction opposite to "front", and "up" and "down" refer to the vertical orientation of the signal light optical system after it is installed on the vehicle. The terms are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
[0044] See also Figures 1 to 7 The first aspect of the utility model provides a signal light optical system, including a first light source, a thick-walled member 1 and a light guide 2, wherein the thick-walled member 1 includes a plurality of thick-walled units 11 arranged in sequence, the first light source is arranged corresponding to the thick-walled unit 11, the thick-walled unit 11 is sequentially formed with a thick-walled light incident surface 114, a collimating portion 112 and a curved light emitting surface 111 along the propagation direction of the light, the light guide 2 includes light guide unit 116 arranged in sequence and corresponding to the thick-walled unit 11, the light guide unit 116 has a light guide emitting surface 21 When in use, the light emitted by the first light source enters the thick-walled unit 11 through the thick-walled light incident surface 114, and then is collimated by the collimating portion 112 to form parallel light or quasi-parallel light, and then emitted to the curved light exit surface 111, and then projected to the light guide unit 116 through the curved light exit surface 111, and is projected through the light guide unit 116 to form a light pattern, and at least one exit focus 113 of the curved light exit surface 111 is arranged within a 5 mm radius of the incident focus 22 of the light guide exit surface 21 of the light guide unit 116.
[0045] It should be noted that, for at least one exit focus 113 of the curved light exit surface 111, which is arranged within a 5 mm radius range of the incident focus 22 of the light guide light exit surface 21 of the optical guide unit 116, it can be understood that, because the exit focus 113 does not exist as a physical entity, the curved light exit surface 111 can have one exit focus 113, or can have a focal line formed by several exit focuses 113. Therefore, when setting the curved light exit surface 111, it is sufficient to ensure that at least one exit focus 113 of the curved light exit surface 111 is within a 5 mm radius range of the incident focus 22 of the light guide light exit surface 21.
[0046] Specifically, see Figure 2 As a preferred embodiment of the utility model, the exit focus 113 of the curved light exit surface 111 is located in front of the thick-walled unit 11, and the incident focus 22 of the light guide exit surface 21 is located behind the light guide unit 116, and the two overlap, so that the light converged by the curved light exit surface 111 can be completely projected into the light guide unit 116 and emitted by the light guide exit surface 21, avoiding light loss.
[0047] The utility model has a simple structure. Through the cooperation of the collimating part 112 and the curved light-emitting surface 111, the light passing through the thick-walled unit 11 can be converged. By limiting the position of the emission focus 113 of the curved light-emitting surface 111, it can ensure that the converged light is injected into the light guide unit 116 as much as possible, and can be emitted from the light guide light-emitting surface 21 to avoid light loss. At the same time, it can also ensure that when facing a light guide 2 with a special structure, such as the light guide 2 is a square light guide, a circular light guide, a fan-shaped light guide, etc., the light can be effectively transmitted.
[0048] Furthermore, the curved light-emitting surface 111 of the thick-walled unit 11 may be an outer convex curved surface or an inner concave curved surface. Both the outer convex curved surface and the inner concave curved surface can converge light and can be set according to actual usage.
[0049] In addition, as a specific implementation of the present utility model, Figure 2 and Figure 4 As shown, the light guide emission surface 21 of the light guide unit 116 is an outward convex curved surface. This design is to be able to collimate the light received from the thick-walled unit 11 and then project it to form a light pattern, thereby ensuring the light effect of the light pattern.
[0050] It should be noted that if Figure 4 As shown in FIG. 1 , as an embodiment, in order to ensure the uniformity of light propagation, the light guide surface 23 of the light guide unit 116 can be set as a light guide tooth, or the light guide surface 23 can be set as a plane or curved surface with a microstructure to achieve the effect of uniform light. Figure 3 , Figure 4 as well as Figure 5 The plurality of light guide units 116 are only a portion of the light guide 2 in the present invention. In actual use, the light guide 2 can be an integrally formed part, which is convenient for processing and installation.
[0051] Furthermore, at least one of the curved light-emitting surface 111 of the thick-walled unit 11 and the light-guiding light-emitting surface 21 of the light-guiding unit 116 is provided with an optical pattern, so as to improve the uniformity of the light.
[0052] Further, see Figure 6 and Figure 7 The thick-walled light-entering surface 114 of the thick-walled unit 11 forms an angle of 0° to 90° with the arrangement direction of the thick-walled unit 11, and two adjacent thick-walled light-entering surfaces 114 are arranged parallel to each other, which can ensure that each thick-walled light-entering surface 114 will not affect the light transmission of the adjacent thick-walled unit 11 when receiving the light of the corresponding first light source, thereby improving the light transmission efficiency. In addition, the thick-walled light-entering surface 114 can also be provided with an optical pattern to improve the uniformity of the light.
[0053] Further, as a specific embodiment of the present invention, the collimating portion 112 can be configured as a parabolic reflector or a quasi-parabolic reflector, and the first light source is disposed at the focus of the collimating portion 112, so as to receive the light passing through the thick-walled light incident surface 114 and converge the light to form parallel light or quasi-parallel light, which is incident on the curved light exit surface 111, and then converged to the exit focus 113 by the curved light exit surface 111. The collimating portion 112 is configured as a parabolic reflector or a quasi-parabolic reflector, which has a simple structure on the one hand, and can convert the light into parallel light or quasi-parallel light on the other hand.
[0054] It should be noted that in order to facilitate the installation of other parts inside the headlight later, such as Figure 2 As shown, a step structure 115 is provided on the side wall of the thick-walled unit 11 .
[0055] Secondly, as an embodiment of the present invention, in order to facilitate processing and save processing steps and costs, the thick-walled part 1 can be an integrally formed part.
[0056] As a specific embodiment of the utility model, the thick-walled light incident surface 114 and the collimating portion 112 can be set as a concentrator in the form of a focusing cup, which is integrally formed with the light-passing portion 24 of the thick-walled unit 11. The light incident surface of the concentrator is the thick-walled light incident surface 114. The first light source is arranged at the focus of the concentrator, so that the light emitted by the first light source is converged by the concentrator, transmitted through the light-passing portion 24, and then converged by the curved light-emitting surface 111 to the output focus 113.
[0057] Further, see Figure 2As a specific embodiment of the present invention, the thick-walled light-entering surface 114 and the collimating portion 112 can be set as a concentrator in the form of a concentrating cup, and the thick-walled unit 11 also has a first reflecting surface, which is connected to the concentrator and the light-transmitting portion 24 respectively. The light emitted by the light source is concentrated by the concentrator and then reflected by the first reflecting surface toward the light-transmitting portion 24, and finally converged to the exit focus 113 by the curved light-emitting surface 111. The first reflecting surface can be set as a plane or a total reflection surface to ensure that the parallel light or quasi-parallel light formed after being concentrated by the concentrator continues to propagate in this form.
[0058] As a specific implementation of the utility model, the thick-walled member 1 is connected to at least one end of the light guide member 2 to achieve fixed installation of the thick-walled member 1 and the light guide member 2. Specifically, by adjusting the positions of the exit focus 113 of the curved light exit surface 111 and the incident focus 22 of the light guide light exit surface 12, the relative position relationship between the thick-walled member 1 and the light guide member 2 is confirmed, and then the two are fixed or made into an integral part by an integrated molding method, which is convenient for installation and fixation. In order not to affect the light transmission, the best implementation method is to achieve fixed connection between the ends of the thick-walled member 1 and the light guide member 2. Of course, in actual production, the two can also be installed separately, and the installation method is not limited here.
[0059] As a specific embodiment of the present invention, the signal light optical system also includes a second light source, which is correspondingly arranged at at least one end of the light guide 2. The light emitted by the second light source is incident through the end of the light guide 2, and is reflected by the side wall of the light guide 2 and then emitted from the light guide light-emitting surface 21 to form a light pattern. By setting the second light source, a signal light function different from that achieved by setting the first light source can be achieved. Of course, the second light source can also achieve the same signal light function as the first light source, thereby improving the light efficiency.
[0060] The signal light optical system provided by the first aspect of the utility model has a simple structure, and can converge the light passing through the thick-walled unit 11 through the cooperation of the collimating portion 112 and the curved light-emitting surface 111. By limiting the position of the emission focus 113 of the curved light-emitting surface 111, it can ensure that the light is injected into the optical guide unit 116 as much as possible, and can be emitted from the light guide emission surface 21 to avoid light loss. At the same time, it can also ensure that when facing the optical guide 2 with a special structure, the light can be effectively propagated to avoid light loss.
[0061] The second aspect of the utility model provides a signal light, comprising a signal light optical system of some of the above-mentioned specific implementation modes and examples. In the signal light optical system, a light source is arranged on the light incident side of the thick-walled part 1, and a light source is arranged at the end of the light guide part 2. Different light functions can be combined together, further reducing the structure required for the signal light, and reducing the space occupied by the signal light while ensuring the function of the signal light.
[0062] A third aspect of the present invention provides a vehicle lamp, which includes the signal lamp provided by the second aspect. The signal lamp occupies a small space, which can further reduce the space occupied by the vehicle lamp.
