[0001] Cross Reference of the Present Application
[0002] This application claims priority to Korean Patent Application No. 10-2021-0088712 filed on July 6, 2021, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD
[0003] The present disclosure relates to a lamp for a vehicle, and particularly, to a lamp for a vehicle which can implement various lamp images. BACKGROUND
[0004] Generally, vehicles are equipped with various types of lamps which have a light emitting function for allowing a user to easily recognize objects located around the vehicle during night driving, and a signal function for notifying the driving state of the vehicle to other vehicles or road users.
[0005] For example, vehicles include headlamps and fog lamps (headlights and front lamps) which mainly perform an illumination function, turn signal lamps which mainly perform a signal function, tail lamps, brake lamps, and side lamps, and the installation reference and standards for the lamps for vehicles are prescribed by law so that the lamps fully exert their functions. In recent years, in addition to the illumination device for the lamps for vehicles or the device for notifying a signal to the outside, it is important to provide a differentiated design element for the lamps. Therefore, lamps for vehicles in which light sources are installed on a vehicle in a matrix form have been developed.
[0006] However, because the conventional lamp for a vehicle forms a static lamp image by using light sources installed in a fixed structure, there is a limitation in expressing various designs using a light distribution image. Therefore, there is a need to improve the technology so that a visual effect having an improved design can be obtained through various lamp images in addition to a static lamp image by a simple light source point.

However, the present disclosure is not limited to the embodiments described below or the technical features of the present disclosure are not limited by the described embodiments, and the present disclosure can be variously modified without departing from the technical scope of the present disclosure.

[0037] Figure 6 An operation of a lamp for a vehicle according to an embodiment of the disclosure is shown, and a state in which the moving part and the link part are operated Figure 5 is shown. Figure 7 A lamp for a vehicle according to an embodiment of the disclosure is shown, and a cross-sectional view of a cross-section of Figure 5 is shown. Figure 8 A cross-sectional view of a cross-section of Figure 7 in which the moving part is moved is shown. Figure 9 A cross-sectional view of a cross-section of Figure 8 in which the link part is rotated is shown.
[0038] Referring to Figures 1 to 9 , a lamp 10 for a vehicle according to an embodiment of the disclosure can include a first optical module 110, a second optical module 120, a third optical module 130, a moving part 200, a link part 300, and a driving part 400.
[0039] The first optical module 110 is configured to form a first light distribution pattern using light irradiated by a first light source part 111.
[0040] In detail, the first optical module 110 can include the first light source part 111, and the first light source part 111 can include a first board on which a plurality of first light sources are mounted. For example, the first light source can be a light emitting diode (hereinafter, referred to as an LED), a micro LED, or the like, and the first board can be a printed circuit board (PCB).
[0041] For example, the first board can have the shape of a plate, and the plurality of first light sources can be arranged in a matrix form in rows and columns on the first board. However, the disclosure is not limited thereto. The first light sources can be irregularly arranged on the first board. One or two or more first light sources can constitute a single pixel. The first light sources can be turned on or off in a pixel unit under the control of a controller (not shown). Accordingly, the first light distribution pattern formed by the first optical module 110 can output various images having different shapes, or can output images having different brightness and colors. That is, the first light distribution pattern formed by the first optical module 110 can be changed into various images.
[0042] The second optical module 120 is configured to form a second light distribution pattern using light irradiated by a second light source part 121. One second optical module 120 can be provided around the first optical module 110 or a plurality of second optical modules 120 can be provided. The plurality of second optical modules 120 can be operated as a whole. In addition, the second optical module 120 can be operated separately from the first optical module 110.
[0043] In detail, the second optical module 120 can include a second light source part 121, and the second light source part 121 can include a second board and second light sources. The configuration and structure of the second light source part 121 can be the same as the configuration and structure of the first light source part 111 described above. In detail, the second light sources can be arranged in a matrix form on the second board, and one or more second light sources can constitute a single pixel. The second light sources can be turned on or off in a pixel unit under the control of a controller (not shown), and the brightness and color of the second light sources can be adjusted. Accordingly, the second light distribution pattern formed by the second optical module 120 can be changed into various images.
[0044] The third optical module 130 is configured to form a third light distribution pattern with light irradiated by a third light source part 131. Here, in a state in which the first light source part 111 is moved by the moving part 200 and the second light source part 121 is rotated by the link part 300, light irradiated by the third light source part 131 is output to the outside. That is, the third optical module 130 can be configured to irradiate light to the outside by dynamic changes of the first optical module 110 and the second optical module 120.
[0045] Here, the first optical module 110, the second optical module 120, and the third optical module 130 can be individually turned on or off.
[0046] The moving part 200 is connected to the first light source part 111 and is configured to move the first light source part 111. In detail, the moving part 200 can be coupled to the first light source part 111 and can linearly move the first light source part 111. Accordingly, the first light distribution pattern can implement a three-dimensional image.
[0047] The link part 300 is connected to the second light source part 121 and is configured to rotate the second light source part 121 together with the moving part 200.
[0048] In detail, the link part 300 is configured to rotate the second light source part 121 and can be connected to the moving part 200 and coupled to the second light source part 121. When the moving part 200 moves the first light source part 111, the link part 300 can rotate the second light source part 121 together with the movement.
[0049] The driving part 400 can provide a driving force to the moving part 200 and the link part 300.
[0050] In detail, the driving part 400 can be connected to the moving part 200 to move the moving part 200 forward or backward. In addition, the driving part 400 can operate the link part 300 together with the moving part 200 when moving the moving part 200. Accordingly, the driving part 400 can simultaneously move the first optical module 110 and rotate the second optical module 120.
[0051] When the first optical module 110 and the second optical module 120 are dynamically changed by the driving part 400, light irradiated by the third light source part 131 can be irradiated to the outside. That is, in a state in which the first light source part 111 is moved and the second light source part 121 is rotated, a third light distribution pattern of the third optical module 130 can be included in a lamp image of the lamp for a vehicle according to the present disclosure. Subsequently, when light of the third light source part 131 is added, the total light amount irradiated by the lamp 10 for a vehicle can be increased.
[0052] The lamp image of the total light beam pattern formed by the first light distribution pattern, the second light distribution pattern, and the third light distribution pattern can be changed by the moving part 200 and the link part 300. For example, as described above, the optical modules can be individually turned on or off, and when the moving part 200 and the link part 300 are not driven, the lamp image can be formed by the first light distribution pattern and the second light distribution pattern. Further, when the moving part 200 and the link part 300 are driven, the entire lamp image can be implemented by the first light distribution pattern and the third light distribution pattern, or can be implemented by the first light distribution pattern, the second light distribution pattern, and the third light distribution pattern.
[0053] According to the lamp 10 according to an embodiment of the present disclosure, the entire image of the light distribution pattern can be three-dimensionally and dynamically changed by the moving part 200 and the driving part 400, and thus lamp images of various designs can be implemented.
[0054] Further, according to the present disclosure, the total light amount can be increased while light of the second optical module 120 is increased by adjusting the positions of the first optical module 110 and the second optical module 120, and thus, visibility can be improved during bad weather, and thus, the safety of a vehicle can be secured.
[0055] Further, according to the present disclosure, because the moving part 200 and the link part 300 are operated in linkage with each other by one driving part 400, the driving part 400 can be minimized, and thus, costs can be reduced and the volume and weight thereof can be reduced.
[0056] Meanwhile, the present disclosure can further include a fourth optical module 140. A plurality of fourth optical modules 140 can form a fourth light distribution pattern with light irradiated by a fourth light source part 141, and the plurality of fourth optical modules 140 can be disposed at a periphery of the first optical module 110.
[0057] In detail, each of the fourth optical modules 140 may include a fourth light source unit 141, and the fourth light source unit 141 may include a fourth plate, with multiple fourth light sources mounted on the fourth plate. For example, the fourth light sources may be arranged in rows or columns in a matrix on the fourth plate. One, two, or more fourth light sources may constitute a single pixel. The fourth light sources may be turned on or off in the pixel unit, and their brightness and color may be adjusted. Therefore, the fourth light distribution pattern formed by the fourth optical modules 140 can be varied into various images.
[0058] For example, the fourth optical module 140 may be disposed around the first optical module 110, and may be disposed between adjacent second optical modules in the second optical module. Furthermore, the fourth optical module 140 may be configured to maintain a static state where its position is not adjusted when the moving part 200 and the link part 300 are driven, but this disclosure is not limited thereto.
[0059] The lamp images corresponding to all beam patterns formed by the lamp 10 for a vehicle according to the present disclosure can be mainly classified into a first pattern image formed before the operation of the moving part 200 and the linkage part 300, and a second pattern image formed when the operation of the moving part 200 and the linkage part 300 is performed.
[0060] The first mode image may include a first light distribution pattern and a second light distribution pattern in an initial state. Furthermore, the first mode image may also include a fourth light distribution pattern.
[0061] Specifically, the first mode image is an image formed in a static state where the positions of the first optical module 110 and the second optical module 120 remain unchanged. As described above, the first light source unit 111 and the second light source unit 121 can be configured such that the first light source and the second light source are arranged in a matrix on the board to obtain multiple images in a static state. The first mode image can be an image of the lamp 10 for a vehicle under normal conditions, and a single lamp 10 for a vehicle can obtain multiple images.
[0062] The second mode image may include a first light distribution pattern, a second light distribution pattern, and a third light distribution pattern while the first light source unit 111 is moved and the second light source unit 121 is rotated. Furthermore, the second mode image may include a fourth light distribution pattern.
[0063] Specifically, the second mode image is an image formed when the positions of the first optical module 110 and the second optical module 120 change. The second mode image can be realized from a three-dimensional image by manipulating the first optical module 110 and the second optical module 120, and the amount of light can be increased due to the addition of the third optical module 130. Therefore, it can be realized when multiple images are needed or in inclement weather (e.g., rain).
[0064] Meanwhile, detailed configurations of the moving part 200, the link part 300, and the driving part 400 will be described below. For reference, Figure 1 , Figure 2 and Figures 7 to 9 The first optical module to the fourth optical module are shown, and the first optical module, the second optical module, and the fourth optical module are omitted in Figure 3 , Figure 5 and Figure 6 .
[0065] For example, the driving part 400 can be an actuator. The driving part 400 can include a housing 410, a driving motor (not shown) disposed inside the housing 410, a screw rod receiving a driving force of the driving motor to rotate, and a driving shaft 420 connected to the screw rod to move forward or backward when the screw rod rotates. Accordingly, the driving shaft 420 can enter or exit the housing 410 due to the driving force of the driving motor, thereby moving forward or backward.
[0066] The moving part 200 can include a movable rod 210, a main panel 220, and a movable plate 230.
[0067] The movable rod 210 can extend along a central axis of the driving shaft 420, and one longitudinal end portion thereof can be coupled to the driving shaft 420 to move together with the driving shaft 420.
[0068] In detail, the movable rod 210 can have a rod shape, and a lower end (with respect to the vertical direction of the drawing) facing the driving part 400 can be fixed to an upper end of the driving shaft 420. When the driving shaft 420 enters or exits the housing 410 to move forward or backward, the movable rod 210 can move together with the movement of the driving shaft 420.
[0069] For example, the moving part 200 can further have a holder 250 and a holder holder 251. The holder holder 251 can be disposed at a lower end of the movable rod 210, and the holder 250 can be disposed between the holder holder 251 and the driving shaft 420 to support the driving shaft 420 moving forward and backward when rotating so that the driving shaft 420 can rotate.
[0070] The first light source part 111 can be mounted in the main panel 220, and the main panel 220 can be fixed to opposite longitudinal ends of the movable rod 210.
[0071] In detail, the main panel 220 is a member for linearly moving the first light source part 111, and can be fixed to an upper end (with respect to the direction in the drawing) of the movable bar 210. For example, the main panel 220 can have the shape of a plate, and can be perpendicular to the movable bar 210. The first light source part 111 can be mounted on a surface of the main panel 220 facing the front side. The first optical module 110 can dynamically change an image while moving the main panel 220.
[0072] The movable plate 230 can be fixed to the movable bar 210, and can be spaced apart from the main panel 220. For example, the movable plate 230 can have the shape of a plate and can be parallel to the main panel 220, but the present disclosure is not limited thereto. The components of the third optical module 130 can be mounted on the movable plate 230.
[0073] Meanwhile, the lamp 10 for a vehicle according to the present disclosure can further include a base plate 500. The base plate 500 can be mounted to a lamp cover (not shown), and can function to support the link part 300.
[0074] The base plate 500 can include a main body 510, a hinge coupling part 520, and a link through-hole 540.
[0075] The main body 510 is a portion forming a main body of the base plate 500, and has a through-hole 511 through which the movable bar 210 passes. That is, the main body 510 can have a ring shape.
[0076] A plurality of hinge coupling parts 520 are formed in the main body 510, and can be disposed along a circumference of the through-hole 511. The link through-hole 540 can pass through the main body 510 and can be formed at a position corresponding to the hinge coupling part 520. For example, the hinge coupling part 520 can protrude upward from the main body 510, and the link through-hole 540 can pass through a front surface and a rear surface of the main body 510. The number of the hinge coupling part 520 and the link through-hole 540 can correspond to the number of the second optical module 120.
[0077] The link part 300 can include a rotation panel 310, a first link member 320, a second link member 330, and a link holder 340.
[0078] The second light source part 121 can be mounted on the rotation panel 310, and the rotation panel 310 can be hinge-coupled to the hinge coupling part 520 to be mounted on the base plate 500 so as to be rotatable. The position and the number of the rotation panel 310 correspond to the position and the number of the second optical module 120, and the second light source part 121 can be mounted on a surface of the rotation panel 310 facing the front side. A hinge boss coupled to the hinge coupling part 520 so as to be rotatable can be formed in the rotation panel 310, and the rotation panel 310 can be rotated about the hinge coupling part 520.
[0079] The first link member 320 can be connected to the rotation panel 310 so as to be rotatable, and can pass through the link through-hole 540. The second link member 330 can be connected to the first link member 320 so as to be rotatable. The link holder 340 can pass through the movable bar 210 so as to be movable, and can be coupled to the second link member 330 so as to be rotatable (see Figure 7 ). Here, the number of the first link member 320 and the second link member 330 can correspond to the number of the rotation panel 310.
[0080] In detail, the second link member 330 can be connected to the movable bar 210 through the link holder 340. The link holder 340 can be connected to the movable bar 210 so that the movable bar 210 is slidable. The link holder 340 can not be moved when the movable bar 210 is moved, but can be moved in the case where the movable bar 210 is pressed by the driving shaft 420 when the movable bar 210 is moved. In the case where the link holder 340 is moved, the second link member 330 can be rotated (see Figure 8 ).
[0081] The first link member 320 can be connected to the second link member 330 so as to be rotatable through a rotation pin or the like, and can rotate around the rotation pin together with the second link member 330 when the second link member 330 is rotated. When the first link member 320 is rotated, the first link member passes through the link through-hole 540 to the front side of the base plate 500, and then, the first link member 320 can press the rotation panel 310. The rotation panel 310 can be pressed by the first link member 320 and can be rotated around the hinge coupling portion 520 (see Figure 9 ). Through this process, the movement of the moving portion 200 and the rotation of the link portion 300 can be linked to each other.
[0082] Here, an inclined surface 541 facing the through-hole 511 can be formed on the surface of the through-hole 540. The inclined surface 541 can be formed on the inner surface of the link through-hole 511 facing the through-hole 511, and can be inclined at a certain angle so as to limit the rotation angle of the first link member 320. In detail, referring to Figure 9 , the first link member 320 can contact the inclined surface 541 during its rotation, and the first link member 320 can be inclined toward the center axis by an angle corresponding to the angle of the inclined surface 541. In this way, the rotation angle of the first link member 320 and the rotation panel 310 can be limited due to the angle of the inclined surface 541 of the link through-hole 540.
[0083] The pressing member 430 can be formed at an end of the driving shaft 420. An end of the movable rod 210 can be coupled to the pressing member 430, and the pressing member 430 can be configured to press the link holder 340 such that the rotation panel 310 is rotated by the first link member 320 and the second link member 330 when the movable rod 210 is moved.
[0084] In detail, the pressing member 430 can be formed to have a diameter greater than that of the movable rod 210, and can press the link holder 340 in a moving direction thereof while moving together with the movable rod 210 and contacting the link holder 340.
[0085] The plurality of rotation panels 310 can be disposed along a circumference of the main panel 220, and the rotation angle of the plurality of rotation panels 310 can be changed by the driving portion 400. As described above, the maximum rotation angle of the rotation panel 310 is limited by the link through-hole 540 of the base plate 500. In addition, the rotation angle of the rotation panel 310 can be adjusted according to the degree of driving force of the driving portion 400, that is, the degree to which the pressing member 430 presses the link holder 340. Accordingly, the degree of image change and the output light amount can be adjusted by the third light source portion 131.
[0086] The third light source portion 131 can be mounted on a rear surface of the main panel 220 facing the movable plate 230. That is, the first light source portion 111 can be mounted on a front surface of the main panel 220, and the third light source portion 131 can be mounted on a rear surface of the main panel 220.
[0087] In addition, the third optical module 130 can further include a reflection portion 132. The reflection portion 132 can be mounted in the movable plate 230 to reflect light irradiated from the third light source portion 131. For example, the shape of the reflection portion 132 can have a shape curved in a direction facing the movable plate 230, but the shape of the reflection plate 132 is not limited thereto.
[0088] In addition, light reflected by the reflection portion 132 can be reflected by the rotation panel 310. Here, the rotation panel 310 can be coated with a reflection material to reflect light reflected by the reflection portion 132 to the outside. Here, the reflection material can include aluminum or the like that can reflect light.
[0089] For example, a reflective material can be disposed on a rear surface of the rotation panel 310, and the rotation panel 310 and the second plate member can be formed of a light-transmissive material. Thus, light irradiated by the third light source part 131 can be reflected by the rotation panel 310 after passing through the third light source part 131. As the rotation panel 310 is rotated and the main panel 220 is moved, a space can be formed between the rotation panel 310 and the main panel 220, and light reflected by the rotation panel 310 can be irradiated to the front side through the space. In addition, a reflective material can also be coated on a rear surface of the main panel 220 facing the reflection part 132. Thus, light irradiated by the third light source part 131 and light irradiated to the main panel 220 through the reflection part 132 can be reflected to the reflection part 132 again.
[0090] Meanwhile, the embodiment of the present disclosure can further include a sub panel 600 on which the fourth optical module 140 is installed. In addition, the base plate 500 can further include a panel fixing part 530 disposed between adjacent hinged coupling parts in the hinged coupling part 520, to which the sub panel 600 is fixed.
[0091] That is, the position of the panel fixing part 530 can correspond to the position of the sub panel 600, and can be coupled to the sub panel 600 by bolt fixing. Thus, the sub panel 600 and the fourth optical module 140 coupled thereto can be free from mechanical changes such as rotation or movement. However, as described above, the fourth optical module 140 can change the image in a static state.
[0092] In this way, the light of the light distribution pattern can be three-dimensionally or dynamically changed by the moving part and the driving part according to the lamp for a vehicle according to the embodiment of the present disclosure, and thus a lamp image of various designs can be implemented.
[0093] In addition, according to the present disclosure, when the light of the third optical module is increased by adjusting the positions of the first and second optical modules, the total light amount can be increased, and thus the visibility can be improved during bad weather, and thus the safety of the vehicle can be secured.
[0094] In addition, according to the present disclosure, because the moving part and the link part are interlocked with each other by one driving part, the driving part can be minimized and thus the cost can be reduced, and the volume and weight thereof can be reduced.

[0096] Further, according to the embodiment of the present disclosure, when light of the second optical module is added by adjusting the positions of the first and second optical modules, the overall light amount can increase, and thus, the visibility can be improved during bad weather, and thus, the safety of the vehicle can be secured.
[0097] Further, according to the embodiment of the present disclosure, because the moving part and the link part are interlocked with each other by one driving part, the driving part can be minimized and thus the cost can be reduced, and the volume and weight thereof can be reduced.
[0098] Although specific embodiments of the present disclosure have been described up to now, the spirit and scope of the present disclosure are not limited to the specific embodiments, and those skilled in the art to which the present disclosure belongs can make various modifications or changes without changing the essence of the present disclosure claimed in the claims.
