[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, 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 this application can be understood according to specific circumstances.

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

[0029] The headlights in the prior art cannot ensure uniformity when lit, or in order to ensure uniformity when lit, the headlights have a large depth, occupying more space in the vehicle, which is not conducive to the layout of other components.

[0030] In order to solve the above technical problems, the embodiment of the present application provides an optical module, including a light source and a light guide bracket, the light source is used to emit light; the light guide bracket has a plurality of light-transmitting through holes arranged at intervals, the light source is arranged on the light incident side of the light guide bracket; the light-transmitting through hole is provided with a reflective surface at one end close to the light source, the reflective surface is configured to reflect the light emitted by the light source into the light-transmitting through hole and emit it as parallel light toward a side away from the light source. The following is a detailed description.

[0031] See also 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 through holes 21 arranged at intervals, and the light source 10 is arranged on the light incident side of the light guide bracket 20; a reflective surface 22 is provided at one end of the light-transmitting through hole 21 close to the light source 10, and the reflective surface 22 is configured to reflect the light emitted by the light source 10 into the light-transmitting through hole 21 and emit it toward a side away from the light source 10 as parallel light 13.

[0032] By setting the reflective surface 22, the light emitted by the light source 10 is reflected into the light-transmitting through hole 21, and the light reflected into the light-transmitting through hole 21 is a parallel light 13, which is beneficial to the uniformity of the lighting of the lamp. When the light emitted by the light source 10 directly irradiates into the light-transmitting through hole 21, since the light emitted by the light source 10 is radial, the light emitted from the light-emitting side of the light-transmitting through hole 21 is uneven, and the uniformity of the lighting of the lamp is relatively poor. In order to improve the uniformity of the lighting of the lamp, the light needs a longer propagation distance ( Figure 1 In the viewing angle, the left and right lateral dimensions of the light-transmitting channel need to be large enough to ensure the uniformity of the lighting of the car lights) to adjust and constrain the light, so that the light emitted from the light-emitting side of the light-transmitting through hole 21 is uniform, but it will take up more car light space, which is not conducive to the layout design of the car lights and other vehicle components, and increases the production cost in the design of car lights for tilting and other shapes.

[0033] In this embodiment, by setting the reflective surface 22, the light emitted by the light source 10 does not need to be directly irradiated into the light-transmitting through hole 21, which can effectively reduce the depth of the light guide bracket 20 (i.e. Figure 1 In the viewing angle, the left and right lateral dimensions of the light guide bracket 20 are small, and the light reflected by the reflecting surface 22 is arranged in parallel, which can ensure the uniformity of the headlights when they are turned on; and the depth of the light guide bracket 20 is reduced, and the path of light propagation becomes shorter, that is, the energy loss of the light when it is emitted from the light guide bracket 20 is less, which effectively improves the brightness of the headlights when they are turned on.

[0034] It should be noted that the shape of the reflective surface 22 is determined according to the installation position of the light source 10 and the shape of the light-emitting surface 24 of the light guide bracket 20, so as to ensure that the light reflected by the reflective surface 22 enters the light-transmitting through hole 21 in parallel. In addition, the shape of the light-emitting surface 24 of the light guide bracket 20 is determined according to the specific shape of the headlight. In this embodiment, the arrangement of the light source 10, the reflective surface 22 and the light-transmitting through hole 21 can meet the use of headlights of different shapes, reduce the depth of the headlight to reduce the space occupied, and effectively improve the uniformity and brightness of the headlight.

[0035] See also Figure 1 , Figure 2 as well as Figure 5 In one embodiment, the light emitted by the light source 10 has a first axis 11, and the first axis 11 is configured to pass through the optical center of the light source 10 and through the opening periphery of the light-transmitting through hole 21 away from the light source 10; a blocking protrusion 23 is provided at one end of the light-transmitting through hole 21 close to the light source 10, and the blocking protrusion 23 is integrally arranged with the hole wall of the light-transmitting through hole 21; in the same light-transmitting through 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-transmitting through hole 21 away from the light source 10.

[0036] In this embodiment, by setting the blocking protrusion 23, it is possible to prevent the light emitted by the light source 10 from being directly emitted from the light-transmitting through hole 21, that is, the light emitted by the light source 10 will not directly form bright light on the light-emitting surface 24 of the light-guiding bracket 20, and the light-emitting surface 24 of the light-guiding bracket 20 only receives the light of the light source 10 reflected from the reflecting surface 22, thereby avoiding the formation of bright spots on the light-emitting surface 24 and effectively improving the uniformity of the lighting of the vehicle lamp. In addition, the blocking protrusion 23 is integrally arranged with the hole wall of the light-transmitting through hole 21, which is convenient for the processing and forming of the light-guiding bracket 20, and is conducive to the setting of the relative position between the blocking protrusion 23 and the light source 10, and can ensure that the blocking protrusion 23 effectively blocks stray light (light directly irradiated on the light-emitting surface 24, the same below).

[0037] In this embodiment, the blocking protrusion 23 is arranged opposite to the reflecting surface 22, which can ensure that the light source 10 has sufficient incident space, and avoid the blocking protrusion 23 blocking the effective light emitted by the light source 10 (part of the light used to reflect the parallel light 13, the same below). In this embodiment, the first axis 11 passes through the light-transmitting through hole 21 away from the opening periphery of the light source 10, and the blocking protrusion 23 extends to the first axis 11, that is, at Figure 1In the viewing angle, among the light rays above the first axis 11 (the light rays directly emitted by the light source 10), except for the part of the light rays irradiated to the reflecting surface 22, the other light rays will directly irradiate the hole wall of the light-transmitting through hole 21, and will not form a bright spot on the light-emitting surface 24; the light rays below the first axis 11 (the light rays directly emitted by the light source 10) will be blocked by the blocking protrusion 23 to avoid directly irradiating the light-emitting surface 24 to form a bright spot.

[0038] It should be noted that the blocking protrusion 23 extends to the first axis 11, that is, the blocking protrusion 23 does not exceed the first axis 11, and does not block the light above the first axis 11, thereby preventing the blocking protrusion 23 from blocking the parallel light 13 reflected by the reflective surface 22, thereby preventing the uniformity and brightness of the lighting of the vehicle lamp from being affected. The shape of the blocking protrusion 23 is comprehensively considered based on factors such as the arrangement position of the light source 10 and the shape of the reflective surface 22.

[0039] In one embodiment, in the same light-transmitting through hole 21, the blocking protrusion 23 extends from the hole wall of the light-transmitting through hole 21 toward the light source 10, and the surface of the blocking protrusion 23 facing the light-transmitting through hole 21 is flush with the hole wall of the light-transmitting through hole 21. Figure 1 and Figure 2 As shown in the blocking protrusion 23a.

[0040] In this embodiment, the top of the blocking protrusion 23 ( Figure 1 The blocking protrusion 23 does not block the parallel light 13 reflected from the reflecting surface 22, thereby ensuring the brightness of the light when the car is lit. Such a setting is beneficial to the production and processing of the light guide bracket 20, for example, it is convenient to demould the light guide bracket 20 during injection molding.

[0041] In some embodiments, the extending direction of the blocking protrusion 23 may be toward the reflecting surface 22. Figure 1 and Figure 2 but not limited thereto, and is considered comprehensively according to 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 hole wall of the light-transmitting through hole 21 adjacent to the first surface 231 and the first surface 231 is α, satisfying: 145°≤α≤180°, for example, 145°, 150°, 160°, 170°, 180°, etc.

[0043] It should be noted that when the value of α is 180°, the arrangement of the blocking protrusion 23 is as follows: Figure 1 and Figure 2As shown in the blocking protrusion 23a, the first surface 231 is the surface of the blocking protrusion 23a facing upward; when the value of α is 145°, the arrangement of the blocking protrusion 23 is as follows Figure 1 and Figure 2 As shown in the 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 close to the light source 10 will tilt downward to the right ( Figure 1 In this case, the blocking protrusion 23a needs to be longer ( Figure 1 When the value of α is less than 145°, the blocking protrusion 23b will gradually extend toward the upper left. At this time, the upper and lower vertical directions of the blocking protrusion 23b ( Figure 1 If the viewing angle) is too large, it will block part of the parallel light 13 reflected from the reflecting surface 22, thereby reducing the lighting brightness.

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

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

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

[0048] It should be noted that, in some embodiments, the second surface 232 may also be arranged to be lower on the left and higher on the right ( Figure 4 The left side is lower and will not affect the emission of parallel light 13, which is determined according to the specific design of the lamp.

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

[0050] In the present embodiment, the light emitting surface 24 is arranged in a plane. When the value of β is less than 20°, the angle is too small, the light emitting surface 24 tends to be parallel to the second axis 12, the modeling difficulty of the light guide bracket 20 increases, and the production cost increases; when the value of β is greater than 70°, the light emitting surface 24 tends to be perpendicular to the second axis 12, which is a relatively conventional design. When the light guide bracket 20 is actually used in the car lamp, the car lamp is basically facing the front of the vehicle, and there are fewer styles of car lamp shape that can be designed, that is, the design of the car lamp shape is limited, which is not conducive to the diversity of car lamp design to meet the personalized usage needs of customers.

[0051] Therefore, when 20°≤β≤70°, the shape design of the vehicle lamp is diverse, which can meet the personalized use needs of customers. At the same time, the shape difficulty of the light guide bracket 20 is relatively small, thereby reducing the production cost.

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

[0053] See also Figure 2 In one embodiment, the parallel light 13 emitted from the light source 10 and reflected by the reflecting surface 22 has a second axis 12, and the second axis 12 is configured to be parallel to the parallel light 13; the light guide bracket 20 has a light emitting surface 24, and the light emitting surface 24 is set as a curved surface convex toward the side away from the light source 10. The intersection of the second axis 12 and the light emitting surface 24 is recorded as point A, and the tangent plane of the light emitting surface 24 passing through point A is used as the reference plane λ. The angle between the second axis 12 and the reference plane is θ, which satisfies: 20°≤θ≤70°, for example, 20°, 30°, 40°, 45°, 50°, 60°, 70°, etc.

[0054] In the present embodiment, the light emitting surface 24 is arranged as a curved surface. When the value of θ is less than 20°, the angle is too small, the light emitting surface 24 tends to be parallel to the second axis 12, the modeling difficulty of the light guide bracket 20 increases, and the production cost increases; when the value of θ is greater than 70°, the light emitting surface 24 tends to be perpendicular to the second axis 12, and the design is relatively conventional. When the light guide bracket 20 is actually used in the car lamp, the car lamp is basically facing the front of the vehicle, and there are fewer styles of car lamp shape that can be designed, that is, the design of the car lamp shape is limited, which is not conducive to the diversity of car lamp design to meet the personalized usage needs of customers.

[0055] Therefore, when 20°≤θ≤70°, the shape design of the vehicle lamp is diverse, which can meet the personalized use needs of customers. At the same time, the shape difficulty of the light guide bracket 20 is relatively small, thereby reducing the production cost.

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

[0057] In addition, the cutting plane is a section of a point on the curved surface, and the light emitting surface 24 is a curved surface, which further enhances the diversity of the lamp shape design; in some embodiments, the light emitting surface 24 can also be a combination of a plane and a curved surface, but is not limited to this.

[0058] See also Figure 1 In one embodiment, the light guide bracket 20 has a light emitting surface 24, and each light-transmitting through hole 21 corresponds to a light source 10; the distance from the light source 10 corresponding to each light-transmitting through hole 21 to the light emitting surface 24 and the corresponding part of the light-transmitting through hole 21 is substantially equal.

[0059] In the present embodiment, each light-transmitting through hole 21 corresponds to a light source 10, which can ensure the brightness of the lights while ensuring the uniformity of the lights; and the distances from the light sources 10 corresponding to each light-transmitting through hole 21 to the light-emitting surface 24 are equal, which can ensure that the propagation paths of the light emitted by each light source 10 are equal, that is, the energy of the light reaching the light-emitting surface 24 is equal, effectively ensuring the uniformity of the lights.

[0060] It should be noted that basically equal means that the above distances can be equal or approximately equal, and the difference between the distances is not large, ensuring that the lighting effect is basically uniform. In actual use, there will be some assembly errors, production errors, etc.

[0061] See also Figure 6 In one embodiment, each light-transmitting through hole 21 corresponds to a light source 10 ; a plurality of receiving grooves 25 are provided on the light incident side of the light guide bracket 20 , and the light sources 10 are received in the receiving grooves 25 to space adjacent light sources 10 .

[0062] By placing the light source 10 in the receiving groove 25, when lighting, there will be no light interference between adjacent light sources 10, thereby ensuring the uniformity of the parallel light 13 in each light-transmitting through hole 21, thereby improving the uniformity of the lighting effect of the vehicle lamp.

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

[0064] The technical solution provided in the embodiment of the present application is intended to reflect the light emitted by the light source 10 into the light-transmitting through hole 21 through the setting of the reflecting surface 22, and the light reflected into the light-transmitting through hole 21 is parallel light 13, which is beneficial to the uniformity of lighting the car lights; it can effectively reduce the depth of the light guide bracket 20 without occupying more car light space, which is beneficial to the layout design of other components.
