Abstract
Description
Technical Field
[0001] The present application relates to a thick-walled optical component, a lamp and a thick-walled part. Background Art
[0002] For lamps, such as car lights, as users demand personalized shapes of lighting patterns and the trend of compact car light structures, it is necessary to arrange improved light-guiding structures in lamps so that they can meet both personalized needs of lighting patterns and compact arrangements in lamps without affecting the settings of other components in the lamps.
[0003] The structure that plays a light-guiding role in the lamp can generally include a light guide and / or a thick-walled part. Both have a light-guiding function. However, the light guide is generally a strip-shaped or column-shaped structure, and light guide teeth are designed in the length direction of the strip-shaped or column-shaped structure. Generally, only two LED light sources need to be set at both ends of the light guide to make the entire light guide illuminate. Therefore, the light guide is also generally called a light guide column or light guide strip. Thick-walled parts are different from light guides. As the name suggests, thick-walled parts are light-transmitting elements with very thick walls. Compared with light guides, which are generally strip-shaped or column-shaped structures, thick-walled parts are wall-shaped structures. Compared with light guides, the brightness of the corresponding lamps of thick-walled parts is greater than that of light guides, but the cost is also higher than that of light guides.
[0004] The optical path provided by the current thick-walled parts is generally that the light incident surface and the light emitting surface of the thick-walled parts are on the same horizontal line, that is, the light enters the thick-walled parts from the light incident surface, and is emitted from the light emitting surface in the thick-walled parts along the incident direction of the light.
[0005] Therefore, in order to meet the demand for personalized shapes of lighting patterns and the demand for compact structure of headlights, if a more complex lighting pattern is required, a light guide structure is generally used to achieve it. The light source enters the light guide facing it, and is reflected by the light guide teeth in the light guide to transfer the light to the light exit surface. For example, the light entry path and the light exit path can be perpendicular to each other. However, this solution has low brightness. If a higher brightness is to be achieved, a large number of light guides need to be set up, which cannot meet the demand for compact structure of the lamp.
[0006] Therefore, there is a need in the art for a thick-walled optical component, a lamp, and a thick-walled part that can achieve complex lighting patterns with higher brightness and also satisfy the compactness of the lamp structure, so that the space layout of a vehicle using the lamp is easy.

[0046] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.
[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and therefore the present application is not limited to the specific embodiments disclosed below.

In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.
[0051] The lamps described in the following embodiments take vehicle lamps as an example, which may be exterior lamps of a vehicle, such as headlights, but are not limited thereto and may also be lamps for other scenarios.
[0052] refer to Figures 1 to 7 As shown, in some embodiments, the thick-walled optical component (10) of the lamp includes a light source component 1 and a thick-walled component 2 for guiding the light beam emitted by the light source component 1.
[0053] like Figure 1 as well as Figure 2 As shown, the light source 1 can emit a light beam. The light source 1 can be, for example, an LED light source, integrated on a printed circuit board 3, i.e., a PCB board. Figure 1 as well as Figure 2 As shown, the number of light source components 1 can be multiple, that is, all light source components 1 are integrated and arranged on the same printed circuit board 3. A single light source component 1 is a single LED lamp bead, corresponding to the light incident surface 21 of a single thick-walled component 2. Preferably, as Figure 1 as well as Figure 2 As shown, the optical unit 200 includes a plurality of light incident surfaces 21 distributed along the width direction, and the number of light source elements 1 is a plurality of light source elements 1 distributed along the width direction, and each light incident surface 21 corresponds to a single light source element 1; the spacing between adjacent light source elements 1 and light incident surfaces 21 in the extension direction is equal, so that the light effect provided by the optical component is more uniform.
[0054] like Figure 1 As shown, the thick-walled member 2 includes an optical unit 200, and the optical unit 200 includes a light incident surface 21, a first reflection surface 22, a second reflection surface 23, and a light emitting surface 24 arranged from upstream to downstream, and the light incident surface 21 and the light emitting surface 22 are arranged non-collinearly. In the description here, "upstream" and "downstream" are relative to the propagation direction of light, that is, the position closer to the light source is upstream.
[0055] The function of the light incident surface 21 is to converge the light beam emitted by the light source 1. Its specific structure can be as follows: Figures 1 to 3 As shown, each light incident surface 21 is a combination of a curved surface and a toothed structure, but this is not a limitation, as long as it is a light incident surface that can converge the light beam. Figures 4 to 7 As shown, the structures of the first reflective surface 22 and the second reflective surface 23 are also arranged one-to-one corresponding to the light incident surface 21. In addition, the first reflective surface 22, the second reflective surface 23, and the light emitting surface 24 can all have optical patterns to improve the light efficiency of the optical component. The specific pattern of the optical pattern is not limited to that shown in the figure and can be designed and adjusted according to the specific light efficiency requirements.
[0056] like Figure 1As shown, the optical path structure provided by the optical unit 200 of the thick-walled member 2 includes: the light beam is emitted from the light source member 1, enters the thick-walled member 2 from the light incident surface 21, propagates along the first direction D1, reflects from the first reflection surface 22, propagates along the second direction D2, reflects from the second reflection surface 23, propagates along the third direction D3, and finally exits the thick-walled member 2 from the light exit surface 22 which is not collinear with the light incident surface 21. It can be understood that the second direction is the propagation direction of the light after the reflection from the first direction, the third direction is the propagation direction of the light after the reflection from the second direction, the first direction is not parallel or collinear with the second direction, the second direction is not parallel or collinear with the third direction, but the first direction and the third direction may be parallel, but not collinear.
[0057] It can be understood that the above “light incident surface 21 and light emitting surface 22 are not arranged in a colinear manner” means that the light incident surface 21 and the light emitting surface 22 are not on the same horizontal line as in the existing solution, that is, the light enters the thick-walled member from the light incident surface, and is emitted from the light emitting surface in the thick-walled member along the incident direction of the light incident, but the light incident surface 21 and the light emitting surface 22 are staggered. If the light incident surface 21 and the light emitting surface 22 are arranged in a colinear manner, the light beam will eventually be emitted from the thick-walled member 2 along the first direction as shown by the dotted line.
[0058] It can be understood that the meaning of the thick-walled part 2 here, as recorded in the previous text, is different from that of the light guide. The light guide is generally a strip-shaped or column-shaped structure, and light guide teeth are designed in the length direction of the strip-shaped or column-shaped structure. Generally, only two LED light sources need to be set at both ends of the light guide to make the entire light guide illuminate. Therefore, the light guide is also generally called a light guide column or light guide strip. The thick-walled part is different from the light guide in that the thick-walled part, as the name implies, is a light-transmitting element with a very thick wall. Compared with the light guide, which is generally a strip-shaped or column-shaped structure, the thick-walled part is a wall-shaped structure. Compared with the light guide, the brightness of the corresponding lamp of the thick-walled part is greater than that of the light guide, but the cost is also higher than that of the light guide. The material of the thick-walled part 2 can be transparent PC, PMMA and other common light-guiding materials, but it is not limited to this.
[0059] The beneficial effect of adopting the above embodiment is that by arranging the first reflecting surface and the second reflecting surface on the thick-walled part, and cooperating with the light incident surface and the light emitting surface to provide a change in the direction of the light beam in the thick-walled part, a complex lighting pattern is achieved through the thick-walled part, and the brightness is high. Moreover, since the light incident surface and the light emitting surface are non-collinearly arranged, the thick-walled optical component can flexibly adapt to the layout space requirements inside the lamp, meet the requirements of the compact structure of the lamp, and is beneficial to the spatial layout of the vehicle.
[0060] Continue to refer Figure 1As shown, the specific structure of the optical unit 200 can be that, in some embodiments, the upstream end of the optical unit 200 provides a light entrance surface 21, and the downstream end provides a light exit surface 24, the thick-walled member 2 has an inner wall surface 201 and an outer wall surface 202 opposite to the inner wall surface 201, and one side of the inner wall surface 201 and the outer wall surface 202 is provided with a first reflection surface 22, and the other side is provided with a second reflection surface 23. The concepts of inner and outer sides here are relative, and the outline of the optical unit 200 is used as the boundary, and the outline on the same side as the light exit direction is the outer side, and the opposite side is the inner side. Figure 1 As shown, the outer side is provided with a first reflection surface 22, and the inner side is provided with a second reflection surface 23. There are multiple first reflection surfaces 22 and second reflection surfaces 23, that is, the number of the first reflection surfaces 22 and the second reflection surfaces 23 described above corresponds to the number of the light incident surface 21, wherein the distribution structure of the multiple reflection surfaces can be that the multiple first reflection surfaces 22 shown in the figure are located on the outer wall surface 202, and the adjacent two first reflection surfaces 22 are in the shape of steps that are sequentially upward. The multiple second reflection surfaces 23 are located on the inner wall surface 201, and the adjacent two multiple second reflection surfaces 23 are in the shape of steps that are sequentially upward. The above structure optical unit 200 is adopted, which makes the structure of the optical component more compact. Reference Figures 5 to 7 As shown, the specific structure of the thick-walled component 2 can be that, in some embodiments, the thick-walled component 2 includes a first part 2001, a second part 2002 and a middle part 2003 connecting the first part 2001 and the second part 2002; the first part 2001 and the second part 2002 respectively have an optical unit 200 and a corresponding light source component 1; the size of the middle part 2003 in the width direction is smaller than the size of the first part 2001 and the second part 2002 in the width direction, so that the first part 2001, the second part 2002 and the middle part 2003 form a hollow structure 2004. For example, as shown in the figure, the first part 2001 and the second part 2002 of the thick-walled part 2 have their own optical components 200, and the middle part 2003 also has a light-emitting surface 24, so that the middle part 2003 can be connected to the first part 2001 and the second part 2002 at both ends like a bridge, and the hollow structure formed provides space for arranging other components in the lamp, making the lamp structure more compact, and also providing personalized complex lighting patterns. For example, different numbers of light source components 1 can be set through the first part 2001 and the second part 2002 to achieve different lighting effects, such as Figure 7 As shown, six light incident surfaces 21, i.e., six LED lamp beads, are arranged on one side of the first part 2001, while four light incident surfaces 21, i.e., four LED lamp beads, are arranged on one side of the second part 2002 to form a light effect with asymmetric brightness. It can be understood that the number of light source components 1 corresponding to the first part 2001 and the second part 2002 may also be the same, and the number of light source components 1 may be adjusted according to the actual light effect and pattern requirements.
[0061] Continue to refer Figures 5 to 7 As shown, in some embodiments, the first part 2001 and the second part 2002 are respectively arranged at the first connecting pin 20011 and the second connecting pin 20021 on the outside, and the thick-walled component 2 is fixedly connected to the printed circuit board 3 through the first connecting pin 20011 and the second connecting pin 20021. For example, the connecting pins and the printed circuit board, as well as the heat sink and other components in the lamp can be connected by screws as connecting members, so that the thick-walled optical component can be stably and reliably installed in the lamp, and the structure is further compact. Preferably, the middle part 2003 includes a third connecting pin 20031, and the thick-walled component 2 is fixed at one end in the height direction, such as the bottom, through the first connecting pin 20011 and the second connecting pin 20021, and fixed at the other end in the height direction, such as the top, through the third connecting pin 20031, so that the installation of the thick-walled component in the lamp is further stable and reliable.
[0062] As described above, the present application further provides a thick-walled member 2, that is, the thick-walled member 2 can be used as a separate component to constitute the thick-walled optical assembly 10 described in the above embodiment, that is, the thick-walled member 2 includes an optical unit 200, including a light incident surface 21, a first reflection surface 22, a second reflection surface 23, and a light emitting surface 24 arranged from upstream to downstream, and the light incident surface 21 and the light emitting surface 22 are arranged non-collinearly; wherein, the optical path structure provided by the optical unit 200 of the thick-walled member 2 includes: after the light beam enters the thick-walled member 2 from the light incident surface 21, it propagates along the first direction, is reflected by the first reflection surface 22, propagates along the second direction, is reflected by the second reflection surface 23, and propagates along the third direction, and the light beam finally exits the thick-walled member 2 from the light emitting surface 22 arranged non-collinearly with the light incident surface 21. Thus, it is possible to provide a complex lighting pattern with high brightness and a relatively compact structure.
[0063] In summary, the beneficial effects of the thick-walled optical components, lamps and thick-walled parts of the present application include but are not limited to, by setting the first reflective surface and the second reflective surface on the thick-walled part, and cooperating with the light incident surface and the light emitting surface to provide a change in the direction of the light beam in the thick-walled part, so that a complex lighting pattern is achieved through the thick-walled part with high brightness, and because the light incident surface and the light emitting surface are non-collinearly arranged, the thick-walled optical component can flexibly adapt to the layout space requirements inside the lamp, meet the requirements of the compact structure of the lamp, and is beneficial to the spatial layout of the vehicle.
[0064] Although the present application has been described with reference to the current specific embodiments, ordinary technicians in this technical field should recognize that the above embodiments are only used to illustrate the present application, and various equivalent changes or substitutions may be made without departing from the spirit of the present application. Therefore, as long as the changes and modifications to the above embodiments are within the essential spirit of the present application, they will fall within the scope of the claims of the present application.
