[0004] In particular, since the lighting design of lighting equipment contributes to the high quality of products, the lighting design and lighting effects of vehicles are considered important.

[0005] Typically, lighting devices require multiple light sources to achieve various lighting patterns, which increases manufacturing costs.

[0014] The light output member may include: a transmission area including a light transmission part; a plurality of pattern areas in which the light transmission part and the light adjustment part are differently combined to realize different patterns; and a shielding area including the light adjustment part.

[0015] In a plurality of pattern areas, the number of light transmitting parts and the number of light adjustment parts may be different or the positions of the light transmitting parts and the positions of the light adjustment parts may be different so that an illumination image formed by emitted light may be realized differently for each of the pattern areas.

[0016] Ends of the plurality of optical fibers may be densely gathered by a multi-ferrule, and a width of the densely gathered optical fibers may be greater than a width of the light adjustment portion in each of the plurality of regions of the light output member.

[0043] Hereinafter, a variable lighting device according to an embodiment of the present disclosure is described with reference to the accompanying drawings.

[0044] According to the embodiments of the present disclosure, Figure 1 As shown, the variable lighting device includes: a light source module 100, which is configured to emit light; a light transmission unit 200, which includes a plurality of optical fibers 210, one end of each optical fiber is set to receive the light emitted from the light source module 100; and a light output member 300, which is located between the light source module 100 and one end of each of the optical fibers 210 and is divided into a plurality of regions. In particular, the plurality of regions of the light output member 300 may include: a first region, which has a light transmission part 310 that transmits light; a second region, which has a moving light adjustment part 320 that blocks or converts light; and a third region, which has a plurality of light transmission parts 310 and a plurality of light adjustment parts 320. The variable lighting device further includes: a driving unit 400, which is connected to the light output member 300 and is configured to selectively change the position of the light output member 300 to allow any one region of the light output member 300 to match between the light source module 100 and the optical fiber 210.

[0045] In the present disclosure, light emitted from the light source module 100 passes through the light output member 300 and moves to the optical fiber 210 of the light transmission unit 200 , so that the light emitted from the optical fiber 210 forms an illumination image.

[0046] In this case, the light output member 300 has a plurality of regions disposed between the light source module 100 and the optical fiber 210 of the light transmission unit 200 and including a light transmitting portion 310 and a light adjustment portion 320 .

[0047] For example, the light output member 300 is divided into a plurality of regions. Some of the plurality of regions include only the light transmission part 310 and transmit light without change. Some of the plurality of regions include only the light adjustment part 320 and block the movement of light. The remaining regions include both the light transmission part 310 and the light adjustment part 320 and transmit only a portion of light. In particular, in the region where the light transmission part 310 and the light adjustment part 320 are provided, the light output member 300 can realize various patterns by combining the light transmission part 310 and the light adjustment part 320. Therefore, the optical fiber 210 of the input light among the plurality of optical fibers 210 changes according to the position of the light output member 300, so that the illumination image realized by the optical fiber 210 can be diversified for each region of the light output member 300.

[0048] For this, the light output member 300 is provided to be position-changed, and the position of the light output member 300 is changed by the driving unit 400. That is, since the optical fiber 210 inputting light varies according to the position of the light output member 300 changed by the driving unit 400, various illumination images can be realized.

[0049] The present disclosure is described in detail. The light source module 100 may include a light source 110 configured to generate light, and a lens part 120 configured to focus the light generated by the light source 110 on one end of an optical fiber 210 .

[0050] like Figure 2 As shown, the light source module 100 may include a light source 110 and a lens component 120. The light source 110 may be composed of an LED, and the lens component 120 may be configured to collect light emitted from the light source 110. In this case, the lens component 120 has an aspherical incident portion so that the light emitted from the light source 110 can be converted into parallel light.

[0051] Therefore, when light emitted from the light source 110 passes through the lens part 120 , the light may have straightness and enter the optical fiber 210 of the optical transmission unit 200 .

[0052] On the other hand, the light output member 300 may be formed in a circular plate shape and configured to be rotatable. A plurality of regions may be defined along an edge of the light output member 300 .

[0053] like Figure 3 and Figure 6 As shown, the light output member 300 is formed in a circular plate shape. A plurality of regions having a light transmission portion 310 and a light adjustment portion 320 are defined along the edge of the light output member 300. In other words, the plurality of regions are defined in a rotation direction based on the rotation center of the light output member 300. The light transmission portion 310 and the light adjustment portion 320 are formed differently in each region.

[0054] In addition, the light output member 300 is rotatably provided and connected to the driving unit 400. When the rotational position of the light output member 300 is changed, the illumination image is determined according to the area matched with the light source 110 and the optical fiber 210.

[0055] The driving unit 400 includes a rotating shaft component 410 configured to rotate according to whether the driving unit 400 is operated. That is, the driving unit 400 includes a rotating shaft component 410 configured to rotate by the operation of the motor 420. The rotating shaft component 410 is connected to the light output member 300 so that the position of the light output member 300 can be changed according to the rotation position of the rotating shaft component 410.

[0056] like Figure 4 As shown, the rotation axis component 410 can be connected to the rotation center of the light output member 300. Figure 5As shown, the rotating shaft component 410 may be connected to the outer peripheral surface of the light output member 300. In this case, a gear connection structure may be applied to connect the rotating shaft component 410 of the driving unit 400 to the outer peripheral surface of the light output member 300, so that the rotation position of the light output member 300 determined by the rotating shaft component 410 may be specified. The driving unit 400 may adopt a solenoid structure instead of the rotating motor 420.

[0057] According to another embodiment of the present disclosure, the light transmission part 310 and the light adjustment part 320 may extend along the rotation radius of the light output member 300. For each region of the light output member 300, the light transmission part 310 and the light adjustment part 320 may be arranged in different patterns along the radial direction of the light output member 300.

[0058] like Figure 6 to Figure 7 As shown, the light transmitting portion 310 and the light adjusting portion 320 extend along a rotation radius in each region of the light output member 300, so that when the region of the input light changes from a current region to another region due to a change in the rotational position of the light output member 300, the unevenness associated with the change in the illumination image of the optical fiber 210 can be minimized.

[0059] In addition, the light transmission part 310 and the light adjustment part 320 can be bent and extended in the rotation direction and obliquely pass through the plurality of optical fibers 210, so that it is possible to minimize the portion of the plurality of optical fibers 210 that is normally adjacent to the light transmission part 310 and the light adjustment part 320. Further, the light transmission part 310 and the light adjustment part 320 are stacked in the radial direction of the light output member 300, which makes it easy to diversify the arrangement of the light transmission part 310 and the light adjustment part 320.

[0060] The light output member 300 of the present disclosure may include a transmission area A including a light transmission part 310 , a plurality of pattern areas B in which the light transmission part 310 and the light adjustment part 320 are differently combined to realize different patterns, and a shielding area C including the light adjustment part 320 .

[0061] In other words, the light output member 300 may have a plurality of regions defined along the rotation direction. These regions may be divided into a transmission region A, a pattern region B, and a shielding region C.

[0062] like Figure 7 As shown, the transmission area A is an area including only the light transmission part 310 and configured to transmit light. In the case where the light output member 300 is made of a material having high permeability, the transmission area A may be a remaining area except the light adjustment part 320.

[0063] like Figure 8As shown, the shielding area C may include only the light adjustment portion 320 and be configured to shield or convert the movement of light. In the present disclosure, the shielding area C may be configured to shield the movement of light. When the optical fiber 210 matches the shielding area C, the output amount of light passing through the light output member 300 may be minimized.

[0064] like Fig. 9 and Fig.10 As shown, the pattern area B can be set as a plurality of pattern areas B. The light transmission part 310 and the light adjustment part 320 are differently set in the pattern area B, so that different patterns can be formed for each pattern area B by combining the light transmission part 310 and the light adjustment part 320. In particular, various embodiments of the light adjustment part 320 can be applied to diversify the illumination image in the pattern area B.

[0065] In one embodiment, Fig.11 As shown, the light adjustment part 320 may have a plurality of optical parts 321 for scattering light emitted from the light source module 100 .

[0066] In other words, the light adjustment part 320 has a plurality of optical parts 321 formed in the direction of the light input emitted from the light source module 100, so that when the light contacts the optical part 321, the light is totally reflected, refracted and scattered. The optical part 321 can be formed differently according to the required amount of light transmitted through the light adjustment part 320. The shape and number of the optical parts 321 of the light adjustment part 320 can be different for each area. For example, the number of optical parts 321 of the light adjustment part 320 in the pattern area B can be gradually increased or decreased along the rotation direction of the light output member 300, so that when the light emitted from the light source 110 is input to the pattern area B, as the light output member 300 rotates, the amount of light input to the optical fiber 210 can be slowly reduced or increased. Therefore, the aesthetic appearance can be improved.

[0067] In another embodiment, the light adjustment portion 320 may be coated with black paint so as not to transmit the light emitted from the light source module 100. As described above, when the light adjustment portion 320 is configured to completely block the light, the light input to the optical fiber 210 is clearly distinguished by the light adjustment portion 320 compared to the light transmitting portion 310 that transmits the light, so that an illumination image can be formed.

[0068] In addition, the plurality of light adjustment parts 320 may be formed to have different colors. As described above, part or all of the light adjustment parts 320 in the pattern area B are formed to have different colors, so that when the light passes through the light adjustment parts 320, the color of the light emitted from the optical fiber can be diversified according to the rotational position of the light output member 300. Therefore, the color of the light emitted from the light source module 100 is converted according to the rotational position of the light output member 300, and then the light is input to the optical fiber 210, so that the optical fiber 210 can realize a lighting image of multiple colors.

[0069] In another embodiment, the number of light transmission parts 310 and light adjustment parts 320 is different, or the positions of the light transmission parts 310 and light adjustment parts 320 are different in the plurality of pattern areas B. Therefore, for each of the pattern areas B, an illumination image formed by emitted light can be realized differently.

[0070] In other words, light is input to the optical fiber 210 matching the light transmission portion 310 among the plurality of optical fibers 210 through the light transmission portion 310 and the light adjustment portion 320 in the pattern area B. Since the light transmission portion 310 and the light adjustment portion 320 are formed to be different in number or position for each of the pattern areas B, the position of the light passing through the pattern area B changes, so that the optical fiber 210 to which the light is input among the plurality of optical fibers 210 changes.

[0071] For example, in the case where the number of light transmitting portions 310 in a specific pattern region B is greater than the number of light transmitting portions 310 in another pattern region B, the amount of light that passes through the specific pattern region B and enters the optical fiber 210 may increase. In addition, since the optical fiber 210 to which light is input among the plurality of optical fibers 210 varies depending on the position of the light adjustment portion 320 in the pattern region B, the optical fiber 210 to which light is emitted may be determined differently for each pattern region B.

[0072] Therefore, for each of the pattern areas B matched between the light source module 100 and the optical fiber 210, the optical fiber 210 of the input light varies according to the rotational position of the light output member 300. Therefore, for each of the pattern areas B, the illumination image generated by the optical fiber 210 is different, so that various illumination images can be realized.

[0073] In one embodiment, ends of the plurality of optical fibers 210 may be densely gathered by the multi-ferrule 220. In each region of the light output member 300, the width of the densely gathered optical fibers 210 may be greater than the width of the light adjustment portion 320.

[0074] The multi-insert 220 has a shape that is transparent inside. The ends of the multiple optical fibers 210 are introduced into the multi-insert 220 so that the optical fibers 210 are densely gathered. In the embodiment according to the present disclosure, seven optical fibers 210 are provided. However, the number of optical fibers 210 may be changed differently according to the lighting design or the required amount of light. In a state where the multiple optical fibers 210 are densely gathered by the multi-insert 220, the multiple optical fibers 210 may be arranged and fixed so that the light emitted from the light source module 100 enters the multiple optical fibers 210.

[0075] In particular, for each region of the light output member 300, the total width of the densely gathered optical fibers 210 is greater than the width of the light adjustment portion 320, so that the light adjustment portion 320 of the light output member 300 clearly distinguishes the passage and shielding of light moving to each of the optical fibers 210. In addition, even in a region where the movement of light emitted from the light output member 300 is maximally restricted, light emitted from the light source module 100 can still be input to some of the optical fibers 210, which can improve the aesthetic appearance by finely emitting light from the optical fibers 210.

[0076] In addition, a single ferrule 230 may be provided at the other end of each optical fiber 210 so that the optical fiber 210 can be fixed to another component. The single ferrule 230 may be made of a plastic material and configured so that the optical fiber 210 is fixedly inserted into the single ferrule 230. Since the other end of the optical fiber 210 is fixed by the single ferrule 230, the optical fiber 210 can be prevented from being damaged during the fixing process. In addition, since the single ferrule 230 with ensured rigidity is coupled to another component, work convenience can be ensured, damage to the optical fiber 210 can be prevented, and the quality of the optical fiber 210 can be maintained.

[0077] In one embodiment, some of the light transmitting portions 310 or the light adjusting portions 320 in the pattern area B may be connected to the light transmitting portions 310 or the light adjusting portions 320 in another pattern area B.

[0078] In the present disclosure, the light transmitting part 310 and the light adjusting part 320 are disposed differently in the plurality of pattern areas B, so that the optical fiber 210 to which light is input is different among the plurality of optical fibers 210. In addition, the position of the light output member 300 is changed by the driving unit 400, thereby determining any one of the plurality of pattern areas B.

[0079] In this case, some of the light transmitting parts 310 or the light adjusting parts 320 in the plurality of pattern areas B are connected to the light transmitting parts 310 or the light adjusting parts 320 in another adjacent pattern area B, so that the same light transmitting parts 310 or the same light adjusting parts 320 are provided in the adjacent pattern areas B. Therefore, in the case where the pattern area B matching the optical fiber 210 is changed to another pattern area B as the position of the light output member 300 changes, light can be input to the same optical fiber 210 or blocked at a portion having the same light transmitting part 310 or the same light adjusting part 320. Therefore, even when the pattern area B changes due to the position change of the light output member 300, a specific optical fiber 210 among the plurality of optical fibers 210 is maintained in a light emitting state, thereby eliminating unevenness caused by the change of the pattern area B. In addition, when the pattern area B matching the optical fiber 210 changes as the position of the light output member 300 changes, the respective optical fibers 210 can sequentially emit light.

[0080] As described above, the light output member 300 may be divided into the transmission area A, a plurality of pattern areas B, and the shielding area C, and various embodiments of the light adjustment portion 320 may be applied so that each pattern area B may realize a different illumination image.

[0081] As described above, according to the present disclosure, each optical fiber 210 of the optical transmission unit 200 selectively emits light by using the light output member 300 whose position is changed by the driving unit 400, thereby realizing various lighting designs.

[0082] In addition, if Fig.12 As shown, a plurality of light source modules 100 and a plurality of light transmission units 200 are provided and configured to match a single light output member 300. Therefore, the optical fiber 210 can be additionally secured and can be provided at various positions as a design element.

[0083] As described above, the present disclosure can be applied to various positions of a motor vehicle, such as interior lamps or headlamps. The plurality of optical fibers 210 can selectively emit light according to the position of the light output member 300 and realize dynamic lighting images, thereby improving the high quality and marketability of the lighting function.

[0084] Although specific embodiments of the present disclosure have been illustrated and described, it will be apparent to those skilled in the art that various modifications and changes can be made to the present disclosure without departing from the technical spirit of the present disclosure.
