Description

Technical Field

[0001] This disclosure relates to a lighting mode changing device. Background Technology

[0002] Typically, vehicles are equipped with lighting devices configured to enable the driver to clearly see objects in the direction of travel while driving at night and to inform other vehicles or people on the street of the vehicle's driving status.

[0003] Besides its function of informing driving status, the design of this lighting device is also crucial. That is, the vehicle image is altered based on the illuminated image provided by the lighting device. Therefore, it is necessary to improve the level of the illuminated image provided by the lighting device.

[0004] Therefore, various lighting devices using optical fibers have been developed in recent years. Optical fibers emit light incident upon them outwards. Thus, various lighting patterns can be achieved based on the characteristics of optical fibers. However, even when using optical fibers, the lighting pattern is still determined by the initial design, thus limiting the realization of a wide variety of lighting patterns.

[0005] The contents disclosed in this section are provided merely to enhance the understanding of the general background of this disclosure and should not be construed as an admission or suggestion in any form that such contents constitute relevant technology known to those skilled in the art. Summary of the Invention

[0008] The fixed plate and the rotating plate can be mounted opposite each other on the housing. The light source module can be mounted on the side of the fixed plate on the housing. Multiple optical fibers can be spaced apart from each other along the periphery of each of the fixed plate and the rotating plate to be connected in a straight line to form an illumination pattern. When the rotating plate rotates, the multiple optical fibers can be interlaced, thereby changing the illumination pattern.

[0016] Multiple rotating plates can be rotatably connected to each other simultaneously via a connecting portion disposed between respective guide frames so as to connect to at least two rotating plates through openings in the guide frames.

[0017] The drive unit can be connected to one of the multiple connecting parts, so that when the connecting part rotates, the multiple rotating plates can rotate simultaneously.

[0018] Multiple gear protrusions may be formed on the circumferential surface of each rotating plate, and connecting protrusions configured to engage with the gear protrusions may be formed on the circumferential surface of each connecting portion.

[0019] With each of the fixed plate, rotating plate, light source module, and guide frame arranged vertically, multiple rotating plates and multiple guide frames can be arranged in series above a single fixed plate. One end of each optical fiber constituting the optical module can be connected to the fixed plate, and the other end of each optical fiber can extend through the rotating plate and be connected to the last rotating plate.

[0020] The drive unit may include: a drive portion configured to generate rotational force; and a drive coupling portion extending vertically from the drive portion, the drive coupling portion being provided with a plurality of gear engagement portions that are connected to corresponding rotating plates through openings in the guide frames.

[0022] Each gear engagement portion may include: a drive gear coupled to a drive coupling to rotate together with the drive coupling; and a driven gear engaging with the drive gear and a corresponding rotating plate among a plurality of rotating plates.

[0023] Multiple guide ribs can be formed on the circumferential surface of each rotating plate, and multiple guide recesses can be formed along the periphery of each guide frame. A corresponding guide rib is inserted into each of the multiple guide recesses.

[0032] Hereinafter, a lighting mode changing device according to a preferred embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0034] like Figures 1 to 3As shown, some forms of lighting mode changing devices of this disclosure include: a fixed plate 100; a rotating plate 200 spaced apart from the fixed plate 100 and configured to be rotatable; and a light source module 300 including a light source 310 configured to emit light and a plurality of optical fibers 320 configured to emit light when light emitted from the light source 310 is incident thereon, wherein one end of each optical fiber 320 is connected to the fixed plate 100 and the other end of each optical fiber 320 is connected to the rotating plate 200 to form an lighting mode, and the lighting mode changes when the rotating plate 200 rotates.

[0035] That is, the fixed plate 100 and the rotating plate 200 are arranged spaced apart from each other, and the optical fiber 320 of the light source module 300 is connected to the fixed plate 100 and the rotating plate 200, thereby forming an illumination pattern through the optical fiber 320. Here, each of the fixed plate 100 and the rotating plate 200 can be formed into any of various shapes depending on the installation position of the optical fiber 320. In some forms of this disclosure, each of the fixed plate 100 and the rotating plate 200 is formed in a disc shape.

[0036] Meanwhile, the light source 310 of the light source module 300 may include an LED. Light emitted from the light source 310 is transmitted to the optical fiber 320, whereby the optical fiber 320 emits light. Each optical fiber 320 is made of glass or a polymer-based resin. Therefore, each optical fiber 320 is flexible, and thus each optical fiber is configured to bend and return to its initial state.

[0037] One end of each optical fiber 320 is connected to the fixed plate 100, and the other end of each optical fiber 320 is connected to the rotating plate 200 to form an illumination pattern. Here, with one end of each optical fiber 320 fixed, when the rotating plate 200 rotates, the other end of each optical fiber 320 moves along the rotation direction of the rotating plate 200, thereby changing the mounting configuration of the optical fiber 320. As described above, since the illumination pattern through the optical fiber 320 changes based on the rotation of the rotating plate 200, the quality and marketability of the illuminated image are improved due to the diversification of illumination patterns.

[0038] Specifically, the fixed plate 100 and the rotating plate 200 are arranged opposite to each other, and the plurality of optical fibers 320 constituting the light source module 300 are spaced apart from each other along the periphery of each of the fixed plate 100 and the rotating plate 200 so as to be connected in a straight line. When the rotating plate 200 rotates, the plurality of optical fibers 320 intersect, thereby changing the lighting mode.

[0039] As from Figure 1As can be seen, a housing 600 can be provided, on which a fixing plate 100 and a rotating plate 200 are mounted. The fixing plate 100 and the rotating plate 200 can be mounted on the upper and lower parts of the housing 600, respectively, such that the fixing plate 100 and the rotating plate 200 are arranged opposite to each other. Here, the light source module 300 can be mounted on the side of the housing 600 where the fixing plate 100 is located. That is, the light source 310 of the light source module 300 is mounted on the side of the housing where the fixing plate 100 is located, and the optical fiber 320 extending from the light source 310 passes through the fixing plate 100 and connects to the rotating plate 200. For this purpose, holes for the optical fiber 320 to extend through can be formed in each of the fixing plate 100 and the rotating plate 200. These holes are formed in the fixing plate 100 and the rotating plate 200 at the same intervals and in the same number. Therefore, when the optical fibers 320 are mounted on the fixed plate 100 and the rotating plate 200, multiple optical fibers 320 extend through the hole H1 of the fixed plate 100, and adhesive is injected into the hole H1 of the fixed plate 100 to secure one end of each optical fiber 320. Subsequently, the other end of each optical fiber 320 extends through the hole H2 of the rotating plate 200 after extending through the fixed plate 100, and adhesive is injected into the hole H2 of the rotating plate 200 to secure the other end of each optical fiber 320. Here, the upper mounting bracket M1 and the lower mounting bracket M2 can be fastened to the upper and lower parts of the housing 600 to secure one end and the other end of each optical fiber 320.

[0040] As described above, the fixed plate 100 and the rotating plate 200 are disposed at the housing 600 in a spaced-apart manner, and the rotating plate 200 is mounted to be rotatable. Here, a plurality of optical fibers 320 are spaced apart from each other along the periphery of each of the fixed plate 100 and the rotating plate 200 so as to be connected in a straight line, thereby forming a configuration as shown in the figure. Figure 2 The lighting pattern shown.

[0041] In this state, when the rotating plate 200 rotates, one end of each optical fiber 320 is fixed to the fixed plate 100, and the other end of each optical fiber 320 moves along the rotation direction of the rotating plate 200. As a result, the multiple optical fibers 320 interweave, thereby allowing the illumination mode to be changed as follows: Figure 3 The illumination pattern is shown. In this case, each optical fiber 320 is made of a flexible material so that it can be stretched, thereby enabling the illumination pattern through the optical fiber 320.

[0042] At the same time, such as Figures 4 to 7As shown, a guide frame 400 may also be included, which is configured to surround the periphery of the rotating plate 200 and guide the rotation and axial movement of the rotating plate 200. The guide frame 400 may be configured separately or may be included in the housing 600. The guide frame 400 is configured to surround the periphery of the rotating plate 200 such that the rotating plate 200 rotates or moves axially within the guide frame 400. Therefore, when the rotating plate 200 rotates, the rotating plate 200 moves axially within the guide frame 400, thereby reducing the tensile length of each optical fiber 320 and ensuring the durability of the optical fiber 320.

[0043] Specifically, a plurality of guide ribs 210 can be formed on the circumferential surface of the rotating plate 200, and a plurality of guide recesses 410 can be formed along the periphery of the guide frame 400. Each of these guide recesses inserts a corresponding guide rib 210, and each guide recess extends in the circumferential direction. That is, the guide ribs 210 of the rotating plate 200 are inserted into the guide recesses 410 of the guide frame 400, thereby rotatably mounting the rotating plate 200 on the guide frame 400. Furthermore, the rotation of the rotating plate 200 is limited by the extension length of each guide recess 410, thereby preventing damage to the optical fiber 320 due to excessive rotation of the rotating plate 200. These guide ribs 210 and these guide recesses 410 can be provided in pairs.

[0044] Here, each guide recess 410 can extend obliquely or curvedly in the direction opposite to the rotating plate 200 and the fixed plate 100. Therefore, when the rotating plate 200 rotates, the guide rib 210 moves along the oblique or curved guide recess 410, thereby moving the guide rib in the axial direction opposite to the fixed plate 100 while the rotating plate 200 rotates. Because the rotating plate 200 moves axially from the guide frame 400, the tensile length of each optical fiber 320 due to the rotation of the rotating plate 200 is reduced.

[0045] It also includes a drive unit 500, which is connected to the rotating plate 200 and configured to generate a rotational force to rotate the rotating plate 200. The drive unit 500 is configured to make the rotating plate 200 rotate automatically, and the lighting mode changes according to the operation of the drive unit 500.

[0046] Specifically, such as Figure 4 and Figure 5As shown, a portion of the circumferential surface of the guide frame 400 is open to form an opening 420, which is configured to expose a portion of the circumferential surface of the rotating plate 200, and the drive unit 500 is connected to the rotating plate 200 through the opening 420 of the guide frame 400. Consequently, the rotating plate 200 in the guide frame 400 is connected to the drive unit 500 through the opening 420 so that it can be rotated by the drive unit 500. Here, the opening 420 can be formed at a position of the guide frame 400 spaced apart from the guide recess 410, and can be formed to have sufficient width such that the connection between the rotating plate 200 and the drive unit 500 is maintained even when the rotating plate 200 moves axially from the guide frame 400. Therefore, the drive unit 500 can be located in the opening 420 of the guide frame 400, and the rotating plate 200 and the drive unit 500 can be connected to each other through the opening 420.

[0047] Specifically, a plurality of gear protrusions 220 may be formed on the circumferential surface of the rotating plate 200, and the drive unit 500 may include a gear portion 520 and a drive portion 510, the gear portion engaging with the gear protrusions 220 of the rotating plate 200, and the drive portion being configured to rotate the gear portion 520 such that the rotating plate 200 rotates together with the gear portion 520.

[0048] That is, the gear protrusion 220 of the rotating plate 200 and the gear portion 520 of the drive unit 500 are connected to each other via a gear structure, so that the rotating plate 200 also rotates when the gear portion 520 rotates via the drive portion 510. Furthermore, the circumferential surface of the rotating plate 200 is exposed through the opening 420 of the guide frame 400, thereby allowing the gear portion 520 to easily engage with the gear protrusion 220 of the rotating plate 200. Here, the gear protrusion 220 may be formed on a portion of the circumferential surface of the rotating plate 200, and the drive portion 510 may be constituted by a motor capable of rotating in alternating directions and can be operated according to user intent or control.

[0049] Therefore, in some forms of this disclosure, the position of the optical fiber 320 changes based on the operation of the drive section 510 according to the rotation of the rotating plate 200, thereby diversifying the illumination pattern. Additionally, during rotation, the rotating plate 200 moves axially from the guide frame 400, thereby reducing the stretching of the optical fiber 320.

[0050] Meanwhile, the fixed plate 100, rotating plate 200, light source module 300 and guide frame 400 disclosed herein can be configured in multiple ways.

[0051] In one embodiment, such as Figures 8 to 10As shown, the fixed plate 100, rotating plate 200, light source module 300, and guide frame 400 can constitute a single lighting component S1, and multiple lighting components can be arranged in the horizontal direction. Each lighting component S1 can be provided with a drive unit 500, so that the lighting component S1 can be controlled individually. Alternatively, multiple lighting components S1 can be controlled by a single drive unit 500.

[0052] When multiple lighting components S1 are configured to be controlled as a whole, each lighting component's guide 400 may be provided with a plurality of openings 420 that are formed opposite to the openings 420 of other guides 400.

[0053] In addition, multiple rotating plates 200 can be rotatably connected to each other via a connecting portion 530 disposed between corresponding guide frames 400 so as to be connected to at least two rotating plates 200 through an opening 420 in the guide frame 400.

[0054] Here, a plurality of gear protrusions 220 are formed on the circumferential surface of each rotating plate 200, and a connecting protrusion 531 configured to engage with the gear protrusions 220 is formed on the circumferential surface of each connecting portion 530, thereby engaging the rotating plate 200 and the connecting portion 530 with each other via gears. Therefore, when the connecting portion 530 rotates, the rotating plate 200 can also rotate. The plurality of connecting portions 530 are formed to have the same size and number as the connecting protrusions 531. Therefore, the rotating plates 200 connected to each other via the connecting portions 530 can rotate at the same rotation angle.

[0055] The opening 420 of each guide frame 400 is formed opposite to the opening 420 of the adjacent guide frame 400, and the connecting portion 530 is disposed between one opening 420 and another opening 420, thereby connecting the rotating plates 200 disposed in the respective guide frames 400 to each other via the connecting portion 530.

[0056] Here, the drive unit 500 can be connected to one of a plurality of connecting parts 530. When the connecting part 530 connected to the drive unit 500 rotates, the plurality of rotating plates 200 can rotate simultaneously.

[0057] Therefore, when one of the components in the connection portion 530 connected to the drive unit 500 rotates, the rotating plates 200 connected to each other via the connection portion 530 can rotate simultaneously, thereby changing the lighting mode of the lighting assembly S1 at the same time.

[0058] With multiple lighting components S1 (each including a fixed plate 100, a rotating plate 200, a light source module 300, and a guide frame 400) arranged horizontally, as described above, the optical fiber 320 of each lighting component can initially form a straight lighting pattern, such as... Figure 9 As shown. When the rotating plate 200 is rotated via the connecting portion 530 through the operation of the drive unit 500, the optical fibers 320 of each lighting component can form an interlaced lighting pattern, such as... Figure 10 As shown.

[0059] On the other hand, in another embodiment, such as Figures 11 to 13 As shown, multiple fixed plates 100, rotating plates 200, light source modules 300, and guide frames 400 can be arranged in the vertical direction. When the components are arranged vertically, as described above, multiple rotating plates 200 and multiple guide frames 400 can be arranged in series above a single fixed plate 100. One end of each optical fiber 320 constituting the light source module 300 can be connected to the fixed plate 100, and the other end of each optical fiber 320 can extend through the rotating plate 200 and be connected to the last rotating plate 200.

[0060] That is, the fixed plate 100 is located at the uppermost or lowermost end, and the rotating plate 200 and the guide frame 400 are arranged in series in a direction opposite to the fixed plate 100. Here, one rotating plate 200 and one guide frame 400 constitute a single lighting unit, and multiple lighting units are arranged vertically above the fixed plate 100. Specifically, one end of each optical fiber 320 constituting the light source module 300 is fixed to the fixed plate 100, and the other end of each optical fiber 320 extends through multiple rotating plates 200 and connects to the last rotating plate 200. That is, the optical fiber 320 is not connected to each rotating plate 200, but extends sequentially from the fixed plate 100 through multiple rotating plates 200.

[0061] Here, the drive unit 500 may include a drive portion 510 configured to generate rotational force and a drive coupling portion 540 extending vertically from the drive portion 510. The drive coupling portion 540 is provided with a plurality of gear engagement portions 541, which are connected to corresponding rotating plates 200 through openings 420 in the guide frame 400. That is, the drive unit 500 includes a drive portion 510 and a drive coupling portion 540. The drive coupling portion 540 extends relatively long in the direction in which the rotating plates 200 are arranged and is provided with gear engagement portions 541 connected to the corresponding rotating plates 200. Therefore, when the drive portion 510 is operated, the rotating plates 200 rotate simultaneously due to the rotation of the drive coupling portion 540.

[0062] Specifically, the gear ratio (number of teeth) between the gear engagement portion 541 of the drive coupling 540 and the rotating plate 200 can be configured to be smaller in the direction away from the fixed plate 100. In this embodiment, one end of each optical fiber 320 is fixed to the fixed plate 100, and the other end of each optical fiber 320 extends through the corresponding rotating plate 200 and connects to the last rotating plate 200. The rotating plates 200 rotate simultaneously. Therefore, when the rotating plate 200 rotates by the operation of the drive portion 510, the overall position of the optical fiber 320 does not change when the rotating plate 200 rotates at the same rotation angle.

[0063] Therefore, the gear ratio between the gear engagement portion 541 of the drive coupling 540 and the rotating plate 200 is configured to be smaller in the direction away from the fixed plate 100. Here, each gear engagement portion 541 may include a drive gear 541a and a driven gear 541b, the drive gear being coupled to the drive coupling 540 to rotate together with the drive coupling 540, and the driven gear engaging with the drive gear 541a and a corresponding rotating plate 200. That is, the rotation angle of each rotating plate 200 based on the rotation of the drive coupling 540 can be changed by setting the gear ratio between the drive gear 541a and the driven gear 541b.

[0064] As an example, such as Figure 11 As shown, assuming that each of the first lighting unit S2, the second lighting unit S3, the third lighting unit S4 and the fourth lighting unit S5 includes a rotating plate 200 and a guide frame 400, and these lighting units are arranged in a direction away from the fixed plate 100, the gear ratio of the driven gear 541b of the gear engagement portion 541 of the rotating plate 200 connected to the lighting unit can be configured in sequence as 1:2:3:4.

[0065] Therefore, when the drive coupling 540 rotates due to the operation of the drive part 510, the rotating plates 200 of the first lighting unit S2, the second lighting unit S3, the third lighting unit S4, and the fourth lighting unit S5 rotate simultaneously. However, since the gear ratios of the driven gears 541b are different from each other, the rotation angle of the rotating plates 200 increases in the order of the first lighting unit S2, the second lighting unit S3, the third lighting unit S4, and the fourth lighting unit S5, thereby enabling changes in the lighting mode based on the overall positional change of the optical fiber 320.

[0066] Furthermore, a plurality of guide ribs 210 may be formed on the circumferential surface of each rotating plate 200, and a plurality of guide recesses 410 may be formed along the periphery of each guide frame 400. Each of these guide recesses is inserted with a corresponding guide rib 210, and each of these guide recesses extends in the circumferential direction. The guide recesses 410 of each guide frame 400 may extend in a direction away from the fixed plate 100. Here, the guide recesses 410 extend in an inclined or bent manner in the direction opposite to the fixed plate 100 of each rotating plate 200. Therefore, because the rotating plate 200 moves axially from the guide frame 400, the tensile length of each optical fiber 320 due to the rotation of the rotating plate 200 is reduced.

[0067] Specifically, in the direction away from the fixed plate 100, the extension length of the guide recess 410 formed in each of the plurality of guide brackets 400 is increased. Since the gear ratio between the gear engagement portion 541 and the rotating plate 200 is configured to be smaller in the direction away from the fixed plate 100, as described above, the rotating plate 200 rotates at a larger rotation angle in the direction away from the fixed plate 100. Therefore, in the direction away from the fixed plate 100, the extension length of the guide recess 410 formed in each of the plurality of guide brackets 400 is increased.

[0068] With the fixed plate 100, rotating plate 200, light source module 300, and guide bracket 400 arranged vertically, as described above, the optical fiber 320 can initially form a straight illumination pattern, such as... Figure 12 As shown. When the rotating plate 200 rotates at different rotation angles based on the operation of the drive unit 500 via the rotation of the drive connector 540, the optical fiber 320 can form an interlaced illumination pattern, such as... Figure 13 As shown.

[0069] In the lighting mode changing device with the above structure, the lighting design is realized through optical fiber, and the grade and marketability of the lighting image are improved by changing the lighting design.

[0070] While preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present disclosure can be implemented in a variety of other embodiments without changing its technical concept or features.
