Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to a light guide component and an automotive lamp. Background Technology

[0002] As people's demands for car appearance increase, the structure of many lamps is becoming smaller, and the space available for optical structures is also decreasing. This necessitates achieving the optical performance and effect of the lamps within a compact structure. In existing technologies, due to the decreasing space for optical structures, thick-walled components are correspondingly thinner to fit the limited space, resulting in a smaller light-emitting area and poor lighting effect. The thickness of the thick-walled components is also insufficient to meet the optical performance requirements. Simply increasing the thickness of the thick-walled components would further reduce the internal space of the vehicle lamp.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The light guide component and vehicle lamp in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the existing technology, as the space of optical structures becomes smaller and smaller, the thickness of thick-walled components is insufficient to meet the optical performance requirements due to their thinness in order to fit the small space, resulting in a small light-emitting area and poor lighting effect. Simply increasing the thickness of the thick-walled components would occupy the internal space of the vehicle headlight.

[0034] To address the aforementioned technical problems, this application provides a light guide component, including a focusing portion, a main body, and a thickened portion. The focusing portion is configured to collimate incident light. In a reference coordinate system, the main body has a first reflecting surface and a first emitting surface at both ends along the X-axis, with the X-axis parallel to the main emitting direction of the light guide component. The thickened portion and the focusing portion are located on the same side of the main body along the Y-axis, and a second emitting surface is provided at the end of the thickened portion away from the focusing portion. The first reflecting surface is configured to reflect light collimated by the focusing portion to the first emitting surface and the second emitting surface. This will be described in detail below.

[0035] See Figure 1-3 The light guide component includes a focusing part 10, a main body 20, and a thickening part 60. The focusing part 10 is configured to collimate incident light. In the reference coordinate system, the main body 20 has a first reflecting surface 21 and a first light emitting surface 22 at both ends in the X-axis direction, and the X-axis is parallel to the main light emitting direction of the light guide component. The thickening part 60 and the focusing part 10 are disposed on the same side of the main body 20 in the Y-axis direction. The end of the thickening part 60 away from the focusing part 10 has a second light emitting surface 62, and the Y-axis direction is parallel to the propagation direction of the light collimated by the focusing part 10. The first reflecting surface 21 is configured to reflect the light collimated by the focusing part 10 to the first light emitting surface 22 and the second light emitting surface 62.

[0036] For ease of explanation, in the following embodiments, the X-axis direction is horizontal, i.e. Figure 2 In the field of view, the left and right directions are represented by the left-right axis, and the Y-axis direction is the vertical direction, i.e. Figure 2 The vertical direction in the field of view.

[0037] exist Figure 2 From the perspective of the main body 20, the thickened portion 60 and the light-concentrating portion 10 are positioned above the main body 20. Specifically, the thickened portion 60 is positioned above the main body 20 and in the space to the right of the light-concentrating portion 10. By setting the thickened portion 60, the light-emitting area of ​​the light guide component (including the first light-emitting surface 22 and the second light-emitting surface 62, the same below) is increased. At the same time, the thickened portion 60 and the light-concentrating portion 10 are positioned on the same side of the main body 20, that is, the thickened portion 60 is set using the longitudinal space of the light-concentrating portion 10. While increasing the light-emitting surface of the light guide component, it can also avoid increasing the overall longitudinal size of the light guide component. This is conducive to the overall flattening design of the light guide component, which can meet the personalized design requirements of the vehicle, reduce the longitudinal space occupation of the light guide component, and facilitate the arrangement of other components inside the headlight.

[0038] It is worth mentioning that the first light-emitting surface 22 and the second light-emitting surface 62 can be set coplanarly, so that the light-emitting surface of the light guide component is flat and smooth, which is conducive to improving the visual aesthetics. In some embodiments, the first light-emitting surface 22 and the second light-emitting surface 62 can also be set non-coplanarly, for example, they can be set at a staggered interval in the horizontal direction. Such a setting can meet the personalized settings of the light guide component and improve the overall visual recognition.

[0039] In addition, the light source 50 that provides light to the focusing part 10 can be set at the focal point of the focusing part 10. After passing through the focusing part 10, the light source 50 is adjusted to be parallel light rays directed toward the first reflecting surface 21, which reduces the divergence of light, improves the utilization rate of light, and helps to improve the light intensity. It is not limited to this, and in some embodiments it can be set in other forms.

[0040] It should be noted that the angle of the first reflecting surface 21 can be adjusted, thereby adjusting the angle of the light emitted after being reflected by the first reflecting surface 21. This can make the light flux received by the first light-emitting surface 22 and the second light-emitting surface 62 the same, which is beneficial to improving the uniformity of the overall lighting.

[0041] In some embodiments, a projection surface η perpendicular to the Y-axis direction is set, and the projection surface η is located on the side of the main body 20 away from the thickened part 60. The maximum distance from the thickened part 60 to the projection surface η is less than or equal to the maximum distance from the focusing part 10 to the projection surface η.

[0042] In this embodiment, the maximum distance from the thickened portion 60 to the projection surface η is less than the maximum distance from the focusing portion 10 to the projection surface η. That is, the focusing portion 10 is higher than the thickened portion 60, and the top of the thickened portion 60 will not exceed the top of the focusing portion 10. In practical applications, the height (longitudinal dimension) of the focusing portion 10 is fixed, and the thickened portion 60 will not be higher than the focusing portion 10, thus avoiding occupying the longitudinal space other than the light guide component (the longitudinal dimensions of the focusing portion 10 and the main body 20). By utilizing the existing height (the height of the focusing portion 10 is fixed), the light-emitting surface area is increased as much as possible, which is beneficial to the arrangement of other components inside the vehicle lamp.

[0043] In some embodiments, the thickened portion 60 may also be provided higher than the light-concentrating portion 10, such as... Figure 5 As shown, the thickened portion 60 still utilizes the space on the right side of the light-concentrating portion 10, thus avoiding an excessively large overall longitudinal dimension of the light guide component; this arrangement still falls within the protection scope of this application.

[0044] In some embodiments, at least two first reflective surfaces 21 are spaced apart along the X-axis, and a projection surface λ perpendicular to the X-axis is set, wherein the orthographic projections of adjacent first reflective surfaces 21 on the projection surface λ at least partially overlap.

[0045] Multiple first reflective surfaces 21 are spaced apart along the X-axis, and the orthographic projections of adjacent first reflective surfaces 21 on the projection plane λ overlap. This reduces the longitudinal dimension of the light guide component, which is beneficial for the narrow and elongated design of the light guide component and can meet the personalized design requirements of automobiles. It also reduces the space occupied by the light guide component in the Y-axis direction, which is beneficial for the arrangement of other components of the headlight.

[0046] It is worth mentioning that the first reflective surface 21 is provided with multiple (such as) Figure 4 As shown, there are three first reflective surfaces 21 (in some embodiments, the number of first reflective surfaces 21 can also be other). The first reflective surfaces 21 can cover a large area of ​​the light-concentrating part 10. That is, the arrangement of multiple first reflective surfaces 21 can receive more light (when the size of the light guide component in the Y-axis direction is fixed, if only one first reflective surface 21 is set, the area of ​​the light-concentrating part 10 that can be covered by the first reflective surface 21 is small, and only a small amount of light collimated by the light-concentrating part 10 can be received. The collimated light that does not shine on the first reflective surface 21 will not shine on the first light-emitting surface 22 and the second light-emitting surface 62). This ensures that more light can be emitted from the first light-emitting surface 22 and the second light-emitting surface 62, improving the utilization rate of light and avoiding low brightness when the light guide component is lit. It also eliminates the need to use higher power LEDs or more LEDs to improve the brightness of the light guide component, reducing the cost of use and heat generation (higher power LEDs or more LEDs will generate more heat), and improving the service life.

[0047] In some embodiments, a projection surface η perpendicular to the Y-axis direction is set, and the projection surface η is located on the side of the main body 20 away from the thickened part 60; the orthographic projection of the light-concentrating part 10 on the projection surface η is located within the orthographic projection of the first reflective surface 21 on the projection surface η.

[0048] In this embodiment, the orthographic projection of the first reflective surface 21 on the projection surface η can completely cover the orthographic projection of the light-concentrating part 10 on the projection surface η. That is, the light rays collimated by the light-concentrating part 10 can all irradiate the first reflective surface 21 and be reflected by the first reflective surface 21 towards the light-emitting surface, thus avoiding the waste of light and improving the utilization efficiency of light.

[0049] It should be noted that the orthographic projection of the first reflecting surface 21 on the projection plane η is the orthographic projection of all the first reflecting surfaces 21 on the projection plane η.

[0050] In some embodiments, a projection surface η perpendicular to the Y-axis direction is set, and the projection surface η is located on the side of the main body 20 away from the thickened part 60; the orthographic projections of adjacent first reflective surfaces 21 on the projection surface η are spaced apart from each other; a connecting surface 23 is provided between adjacent first reflective surfaces 21, and the angle between the connecting surface 23 and the Y-axis direction is α, which satisfies: 3°≤α≤10°, such as 3°, 5°, 7°, 9°, 10°, etc.

[0051] When the value of α is less than 3°, the connecting surface 23 tends to be vertical, which is not conducive to the demolding of the light guide component. When the value of α is greater than 10°, the distance between the orthographic projections of two adjacent first reflective surfaces 21 on the projection surface η is too large. More light will be emitted from this distance and directed towards the non-illuminated area (the area outside the light-emitting surface), resulting in a waste of light. That is, when the value of α is greater than 10°, the size of the connecting surface 23 in the X-axis direction becomes larger, and correspondingly, the size of the first reflective surface 21 in the X-axis direction becomes smaller. The connecting surface 23 will encroach on the first reflective surface 21, and the utilization rate of light will decrease.

[0052] It should be noted that, with Figure 2 Taking the example shown, there are two first reflective surfaces 21. The light illuminating the left first reflective surface 21 is reflected and refracted through the connecting surface 23 into the right first reflective surface 21, and then shines towards the light-emitting surface; the light illuminating the right first reflective surface 21 is reflected and then shines directly towards the light-emitting surface.

[0053] It is worth mentioning that in some embodiments, the light guide component can be processed by other forms of processing methods without considering the demolding angle. That is, the orthographic projections of two adjacent first reflective surfaces 21 on the projection surface η can be adjacent or overlapping, that is, there is no gap between two adjacent projection surfaces, which can make full use of the light.

[0054] In some embodiments, adjacent first reflective surfaces 21 are sequentially referred to as first surface 30 and second surface 40 along the X-axis direction; in the Y-axis direction, the distance from the end of the first surface 30 away from the light-concentrating part 10 to the projection surface η is d1, and the distance from the end of the second surface 40 away from the light-concentrating part 10 to the projection surface η is d2, satisfying: d1>d2.

[0055] The light reflected by the first surface 30 needs to be refracted by the connecting surface 23 before re-entering the main body 20. In this embodiment, d1 > d2, that is, the bottom of the first surface 30 is higher than the bottom of the second surface 40, which can ensure that all the light refracted from the connecting surface 23 is received by the second surface 40 (re-entering the main body 20), and avoid the light being refracted to the bottom of the main body 20 (second surface 40), thus improving the utilization rate of light.

[0056] When d1≤d2, some light will be refracted by the connecting surface 23 and emitted downwards towards the second surface 40, resulting in wasted light. At the same time, when d1<d2, that is, the bottom of the first surface 30 is located below the bottom of the second surface 40, the overall space occupied by the light guide component in the Y-axis direction will be affected.

[0057] In some embodiments, the angle between the first reflecting surface 21 and the X-axis direction is β, which satisfies: 40°≤β≤45°, such as 40°, 41°, 42°, 43°, 44°, 45°, etc.

[0058] When the value of β is less than 40°, the first reflecting surface 21 tends to be horizontal, and the light reflected by the first reflecting surface 21 tends to be vertical, which cannot be well directed to the light-emitting surface, resulting in the loss of light energy. When the value of β is greater than 45°, the first reflecting surface 21 tends to be vertical. In the Y-axis direction, the first reflecting surface 21 needs to have a larger size to meet the size requirements of the first reflecting surface 21 in the X-axis direction, which will make the size of the light guide component in the Y-axis direction larger, which is not conducive to the narrow and long setting of the light guide component.

[0059] By adjusting the angle of the first reflective surface 21, light can be directed more effectively toward the light-emitting surface, improving the efficiency of light use while reducing the space occupied by the light guide component in the Y-axis direction.

[0060] In some embodiments, the thickened portion 60 is provided with a second reflective surface 61 at one end near the light-concentrating portion 10. The second reflective surface 61 is configured to receive a portion of the light reflected by the first reflective surface 21 and emit the light parallel to the X-axis direction.

[0061] By providing the second reflective surface 61 in the thickened portion 60, some light can be reflected and directed towards the second light-emitting surface 62 along the X-axis direction. In other words, by providing the second reflective surface 61, the luminous flux of the second light-emitting surface 62 can be supplemented, which is beneficial to improving the overall lighting uniformity. The light reflected by the second reflective surface 61 is parallel to the X-axis direction, ensuring that the light can be directed towards the second light-emitting surface 62, which is beneficial to improving the overall lighting uniformity.

[0062] It should be noted that the portion of light reflected by the first reflecting surface 21 is only a part of all the light reflected by the first reflecting surface 21. That is, part of the light reflected by the first reflecting surface 21 is directly directed to the light-emitting surface (the light-emitting surface of the entire light guide component, including the first light-emitting surface 22 and the second light-emitting surface 62), and the remaining part is directed to the second reflecting surface 61 and then reflected by the second reflecting surface 61 before being directed to the light-emitting surface.

[0063] In some embodiments, the angle between the second surface 40 and the X-axis direction is 45°. The second surface 40 receives collimated light rays and directs the light rays along the X-axis toward the first light-emitting surface 22. After being reflected by the first surface 30, the light rays are refracted by the connecting surface 23 and re-enter the main body 20, and then direct toward the second reflective surface 61. By setting the angle of the second reflective surface 61, the light rays are finally directed toward the second light-emitting surface 62 along the X-axis direction, which increases the luminous flux of the second light-emitting surface 62 and helps to improve the uniformity of overall illumination.

[0064] It is worth mentioning that in some embodiments, the angle between the second surface 40 and the X-axis direction can be set to other angles. Accordingly, the angles of the first surface 30 and the second reflective surface 61 can be adjusted to adjust the direction of light emission, so as to ensure that the whole is evenly illuminated.

[0065] See Figure 5 The light-concentrating part 10 has multiple components along the X-axis. Correspondingly, multiple light sources 50 are provided, with one light source 50 corresponding to one light-concentrating part 10. Different lighting effects can be achieved by controlling the on / off state of different light sources 50.

[0066] On the other hand, this application also relates to a vehicle light, including any of the aforementioned light guide components.

[0067] The technical solution provided in this application aims to increase the light-emitting area of ​​the light guide component by setting the thickened portion 60. At the same time, the thickened portion 60 and the light-concentrating portion 10 are set on the same side of the main body portion 20, that is, the thickened portion 60 is set using the longitudinal space of the light-concentrating portion 10. While increasing the light-emitting surface of the light guide component, it can also avoid increasing the overall longitudinal size of the light guide component, which is conducive to the overall flat design of the light guide component, can meet the personalized design requirements of the vehicle, reduce the longitudinal space occupation of the light guide component, and is conducive to the arrangement of other components inside the headlight.
