[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixedly connected, or detachably connected, or integrally connected; can be mechanically connected, or electrically connected, or can communicate with each other; can be directly connected, or indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] The optical module and vehicle lamp in the present application will be described in detail below with reference to the drawings and specific embodiments.

[0029] The vehicle lamp in the prior art cannot guarantee uniformity when lighting, or in order to guarantee uniformity when lighting, the longitudinal depth of the vehicle lamp is large, occupying a large space of the vehicle, which is not conducive to the layout of the remaining parts.

[0030] To address the aforementioned technical problems, this application provides an optical module, including a light source and a light guide bracket. The light source emits light; the light guide bracket has a plurality of spaced-apart light-transmitting holes, and the light source is disposed on the light-incident side of the light guide bracket; a reflective surface is provided at one end of each light-transmitting hole near the light source, and the reflective surface is configured to reflect the light emitted by the light source into the light-transmitting hole and emit parallel light rays toward a side away from the light source. This will be described in detail below.

[0031] See Figure 1 and Figure 5 In one embodiment, the optical module includes a light source 10 and a light guide bracket 20. The light source 10 is used to emit light. The light guide bracket 20 has a plurality of light-transmitting holes 21 spaced apart. The light source 10 is disposed on the light-incident side of the light guide bracket 20. A reflective surface 22 is provided at one end of the light-transmitting hole 21 near the light source 10. The reflective surface 22 is configured to reflect the light emitted by the light source 10 into the light-transmitting hole 21 and emit parallel light rays 13 toward the side away from the light source 10.

[0032] By setting the reflective surface 22, the light emitted from the light source 10 is reflected into the light-transmitting aperture 21, and the light reflected into the light-transmitting aperture 21 is a parallel light ray 13, which is beneficial to the uniformity of the headlight illumination. When the light emitted from the light source 10 directly illuminates the light-transmitting aperture 21, because the light emitted from the light source 10 is radial, the light emitted from the light-emitting side of the light-transmitting aperture 21 is uneven, and the uniformity of the headlight illumination is relatively poor. In order to improve the uniformity of the headlight illumination, the light needs to travel a longer distance. Figure 1 From a visual perspective, the horizontal dimensions of the light-transmitting channel need to be large enough to ensure the uniformity of the headlight illumination. This is to adjust and constrain the light, thereby making the light emitted from the light-transmitting hole 21 uniform. However, this will occupy more headlight space, which is not conducive to the layout design of headlights and other vehicle components, and increases production costs in headlight designs with tilted shapes.

[0033] In this embodiment, by setting the reflective surface 22, the light emitted by the light source 10 does not need to directly illuminate the light-transmitting hole 21, which can effectively reduce the depth of the light guide bracket 20 (i.e., Figure 1 From a visual perspective, the light guide bracket 20 has a horizontal dimension (left and right), and the light rays reflected by the reflective surface 22 are arranged in parallel, which can ensure the uniformity of the headlights when they are lit. In addition, the reduction in the depth of the light guide bracket 20 shortens the path of light propagation, which means that the energy loss of light when it is emitted from the light guide bracket 20 is less, effectively improving the brightness of the headlights.

[0034] It should be noted that the shape of the reflecting surface 22 is determined according to the installation position of the light source 10 and the shape of the light outlet surface 24 of the light guide support 20, to ensure that the light reflected by the reflecting surface 22 is parallel to the light transmission hole 21. In addition, the shape of the light outlet surface 24 of the light guide support 20 is determined according to the specific shape of the vehicle lamp. In the embodiment, the light source 10, the reflecting surface 22, and the light transmission hole 21 can meet the requirements of different shapes of vehicle lamps, reduce the depth of the vehicle lamp to reduce the space occupation, and effectively improve the uniformity and brightness of the vehicle lamp lighting.

[0035] Referring to Figure 1 , Figure 2 and Figure 5 , in an embodiment, the light emitted by the light source 10 has a first axis 11, the first axis 11 is configured to pass through the optical center of the light source 10 and pass through the opening periphery of the light transmission hole 21 away from the light source 10; the end of the light transmission hole 21 close to the light source 10 is provided with a blocking protrusion 23, the blocking protrusion 23 is integrally arranged with the hole wall of the light transmission hole 21; in the same light transmission hole 21, the blocking protrusion 23 is arranged opposite to the reflecting surface 22; the blocking protrusion 23 extends to the first axis 11, to prevent the light emitted by the light source 10 from being directly emitted from the end of the light transmission hole 21 away from the light source 10.

[0036] In the embodiment, the blocking protrusion 23 is arranged to prevent the light emitted by the light source 10 from being directly emitted from the light transmission hole 21, that is, the light emitted by the light source 10 will not directly form a bright light on the light outlet surface 24 of the light guide support 20, and only the light emitted by the light source 10 reflected by the reflecting surface 22 is received on the light outlet surface 24 of the light guide support 20, to avoid forming a bright spot on the light outlet surface 24 and effectively improve the uniformity of the vehicle lamp lighting. The blocking protrusion 23 is integrally arranged with the hole wall of the light transmission hole 21, which is convenient for the processing and forming of the light guide support 20, and is conducive to the setting of the relative position between the blocking protrusion 23 and the light source 10, to ensure that the blocking protrusion 23 effectively blocks the stray light (the light directly irradiated on the light outlet surface 24, the same below).

[0037] In the embodiment, the blocking protrusion 23 is arranged opposite to the reflecting surface 22, to ensure that the light source 10 has sufficient incident space and avoid blocking the effective light (the part of the light emitted by the light source 10 for forming parallel light 13, the same below) emitted by the light source 10. In the embodiment, the first axis 11 passes through the opening periphery of the light transmission hole 21 away from the light source 10, and the blocking protrusion 23 extends to the first axis 11, that is, in the same light transmission hole 21, the blocking protrusion 23 is arranged opposite to the reflecting surface 22. Figure 1From the perspective of light, the light rays located above the first axis 11 (light rays directly emitted by the light source 10), except for the part of light rays that illuminate the reflective surface 22, will directly illuminate the wall of the light-transmitting hole 21 and will not form bright spots on the light-emitting surface 24; the light rays located below the first axis 11 (light rays directly emitted by the light source 10) will be blocked by the blocking protrusion 23 to prevent them from directly illuminating the light-emitting surface 24 and forming bright spots.

[0038] It should be noted that the blocking protrusion 23 extends to the first axis 11, meaning that the blocking protrusion 23 will not exceed the first axis 11 and will not block the light above the first axis 11. This avoids the blocking protrusion 23 blocking the parallel light rays 13 reflected by the reflective surface 22, thus preventing it from affecting the uniformity and brightness of the headlight illumination. The shape of the blocking protrusion 23 is determined by a combination of factors, including the arrangement of the light source 10 and the design of the reflective surface 22.

[0039] In one embodiment, within the same light-transmitting aperture 21, a blocking protrusion 23 extends from the aperture wall of the light-transmitting aperture 21 toward the light source 10, and the surface of the blocking protrusion 23 facing the light-transmitting aperture 21 is flush with the aperture wall of the light-transmitting aperture 21, such as... Figure 1 and Figure 2 The middle blocking protrusion 23a is shown.

[0040] In this embodiment, the top of the blocking protrusion 23 ( Figure 1 The viewing angle is flush with the inner wall of the light-transmitting hole 21, and the blocking protrusion 23 will not block the parallel light rays 13 reflected from the reflective surface 22, which can ensure the brightness of the car headlights; and this setting is conducive to the production and processing of the light guide bracket 20, such as the easy demolding of the light guide bracket 20 during injection molding.

[0041] In some embodiments, the extending direction of the blocking protrusion 23 may be towards the reflective surface 22, such as... Figure 1 and Figure 2 As shown in the middle blocking protrusion 23b; but not limited to this, it is also considered in combination with factors such as the actual shape of the light guide bracket 20 and the processing technology of the light guide bracket 20.

[0042] See 3 and Figure 4 In one embodiment, the surface of the blocking protrusion 23 facing away from the light source 10 is the first surface 231; the angle between the wall of the light-transmitting hole 21 adjacent to the first surface 231 and the first surface 231 is α, which satisfies: 145°≤α≤180°, such as 145°, 150°, 160°, 170°, 180°, etc.

[0043] It should be noted that when α is 180°, the arrangement of the blocking protrusion 23 is as follows: Figure 1 and Figure 2As shown in the diagram of the blocking protrusion 23a, the first surface 231 is the surface of the blocking protrusion 23a facing upwards; when α is 145°, the arrangement of the blocking protrusion 23 is as follows. Figure 1 and Figure 2 As shown in the middle blocking protrusion 23b, the first surface 231 is the surface on the left side of the blocking protrusion 23b.

[0044] When the value of α is greater than 180°, the end of the blocking protrusion 23a near the light source 10 will tilt to the lower right. Figure 1 (Viewpoint), at this point, the blocking bump 23a needs to be longer ( Figure 1 The horizontal dimension of the viewing angle is used to block stray light, which increases production cost and difficulty; when the value of α is less than 145°, the blocking protrusion 23b will gradually extend towards the upper left, at which time the vertical direction of the blocking protrusion 23b ( Figure 1 If the viewing angle is too large, it will block some of the parallel light rays 13 reflected from the reflective surface 22, reducing the brightness.

[0045] It should be noted that the value of α can be outside the range, depending on factors such as the design requirements of the headlight and the brightness of the headlight; the goal is to ensure that the blocking protrusion 23 can block stray light to achieve uniform headlight illumination.

[0046] See Figure 4 In one embodiment, the surface of the blocking protrusion 23 that is away from the wall of the light-transmitting hole 21 is the second surface 232, which is parallel to the parallel light ray 13.

[0047] like Figure 4 As shown in some embodiments, the shaded area is also part of the blocking protrusion 23. Although it can effectively block stray light, the shaded area increases the vertical dimension of the blocking protrusion 23, and some parallel light rays 13 will be blocked by the shaded area, reducing the brightness of the headlight. In this embodiment, the second surface 232 is the top surface of the blocking protrusion 23. The second surface 232 is set parallel to the parallel light ray 13. The parallel light ray 13 reflected from the reflective surface 22 will not be blocked by the blocking protrusion 23. It is only necessary to ensure that the top of the right side of the blocking protrusion 23 extends to the first axis 11 to block stray light.

[0048] It should be noted that in some embodiments, the second surface 232 can also be configured with a lower left side and a higher right side. Figure 4 (View angle) The lower left side will not affect the emission of parallel light 13, depending on the specific design of the headlights.

[0049] See Figure 1In an embodiment, the parallel light rays 13 emitted from the light source 10 and reflected by the reflecting surface 22 have a second axis 12 configured to be parallel to the parallel light rays 13; the light guide bracket 20 has an outlight surface 24 arranged in a plane, and an angle β between the second axis 12 and the outlight surface 24 satisfies 20°≤β≤70°, for example, 20°, 30°, 40°, 45°, 50°, 60°, 70°, etc.

[0050] In the embodiment, the outlight surface 24 is arranged in a plane, when the value of β is less than 20°, the angle is too small, the outlight surface 24 tends to be parallel to the second axis 12, the modeling difficulty of the light guide bracket 20 is increased, and the production cost is increased; when the value of β is greater than 70°, the outlight surface 24 tends to be perpendicular to the second axis 12, and the design is deviated from the conventional design, in the actual use of the vehicle lamp, the vehicle lamp is basically directed to the front of the vehicle, the vehicle lamp modeling can be designed in fewer styles, that is, the design of the vehicle lamp modeling is limited, which is not conducive to the diversity of the vehicle lamp design to meet the personalized use requirements of customers.

[0051] Therefore, when 20°≤β≤70°, the modeling design of the vehicle lamp is diverse, the personalized use requirements of customers can be met, the modeling difficulty of the light guide bracket 20 is relatively small, and the production cost is reduced.

[0052] It should be noted that in some embodiments, the value of β can also be out of the range, which is determined according to the actual design requirements, and is not limited thereto.

[0053] Referring to Figure 2 In an embodiment, the parallel light rays 13 emitted from the light source 10 and reflected by the reflecting surface 22 have a second axis 12 configured to be parallel to the parallel light rays 13; the light guide bracket 20 has an outlight surface 24 arranged in a plane, and an angle β between the second axis 12 and the outlight surface 24 satisfies 20°≤β≤70°, for example, 20°, 30°, 40°, 45°, 50°, 60°, 70°, etc.

[0054] In the embodiment, the outlight surface 24 is arranged in a plane, when the value of β is less than 20°, the angle is too small, the outlight surface 24 tends to be parallel to the second axis 12, the modeling difficulty of the light guide bracket 20 is increased, and the production cost is increased; when the value of β is greater than 70°, the outlight surface 24 tends to be perpendicular to the second axis 12, and the design is deviated from the conventional design, in the actual use of the vehicle lamp, the vehicle lamp is basically directed to the front of the vehicle, the vehicle lamp modeling can be designed in fewer styles, that is, the design of the vehicle lamp modeling is limited, which is not conducive to the diversity of the vehicle lamp design to meet the personalized use requirements of customers. In the embodiment, the outlight surface 24 is arranged in a plane, when the value of β is less than 20°, the angle is too small, the outlight surface 24 tends to be parallel to the second axis 12, the modeling difficulty of the light guide bracket 20 is increased, and the production cost is increased; when the value of β is greater than 70°, the outlight surface 24 tends to be perpendicular to the second axis 12, and the design is deviated from the conventional design, in the actual use of the vehicle lamp, the vehicle lamp is basically directed to the front of the vehicle, the vehicle lamp modeling can be designed in fewer styles, that is, the design of the vehicle lamp modeling is limited, which is not conducive to the diversity of the vehicle lamp design to meet the personalized use requirements of customers.

[0055] Therefore, when 20°≤θ≤70°, the styling design of the vehicle lamp is various, the customer's personalized use demand can be met, and the modeling difficulty of the light guide support 20 is small, and the production cost is reduced.

[0056] It should be noted that in some embodiments, the value of θ can also be a value outside the range, which is determined according to the actual design requirement, and is not limited thereto.

[0057] In addition, the tangent plane is the tangent plane of a point on the curved surface, and the light emitting surface 24 is provided as a curved surface, which further improves the diversity of the vehicle lamp styling design. In some embodiments, the light emitting surface 24 can also be a combination of a plane and a curved surface, and is not limited thereto.

[0058] Referring to Figure 1 In an embodiment, the light guide support 20 has a light emitting surface 24, and each light transmission through hole 21 is provided with a light source 10 corresponding thereto; the distance from the light source 10 corresponding to each light transmission through hole 21 to the part of the light emitting surface 24 opposite to the light transmission through hole 21 is substantially equal.

[0059] In the embodiment, each light transmission through hole 21 is provided with a light source 10 corresponding thereto, which can ensure the brightness of the vehicle lamp lighting and also ensure the uniformity of the vehicle lamp lighting; and the distance from the light source 10 corresponding to each light transmission through hole 21 to the light emitting surface 24 is equal, which can ensure that the propagation paths of the light emitted by each light source 10 are equal, i.e., the light energy reaching the light emitting surface 24 is equal, thereby effectively ensuring the uniformity of the vehicle lamp lighting.

[0060] It should be noted that substantially equal means that the above-mentioned distances can be equal or approximately equal, and the difference between the distances is not large, which ensures the basic uniformity of the lighting effect. In actual use, there will be some assembly errors, production errors, etc.

[0061] Referring to Figure 6 In an embodiment, each light transmission through hole 21 is provided with a light source 10 corresponding thereto; the light entrance side of the light guide support 20 is provided with a plurality of accommodating grooves 25, and the light source 10 is accommodated in the accommodating groove 25 to separate adjacent light sources 10.

[0062] By placing the light source 10 in the accommodating groove 25, when lighting, the adjacent light sources 10 will not cause interference of the light, which ensures the uniformity of the parallel light 13 in each light transmission through hole 21, and further improves the uniformity of the vehicle lamp lighting effect.

[0063] On the other hand, the present application also relates to a vehicle lamp comprising the optical module of any one of the preceding.

[0064] By means of the technical scheme provided in the embodiment of the present application, the light source 10 emits reflected light into the light-transmitting through hole 21 through the reflection of the reflection surface 22, and the light reflected into the light-transmitting through hole 21 is parallel light 13, which is beneficial to the uniformity of the vehicle lamp lighting; the depth of the light guide support 20 can be effectively reduced, and more vehicle lamp space is not occupied, which is beneficial to the layout design of the remaining parts.

[0065] In various embodiments of the present application, the terms or descriptions of different embodiments are consistent and can be mutually referred to if there is no special description and logical conflict, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship. In the present application, "at least one" means one or more, and "multiple" means two or more.
