Abstract
Description
Technical Field
[0001] The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp capable of realizing various lamp images.
Background Art
[0002] Generally, vehicles are equipped with various lamps having a lighting function for easily checking objects located around the vehicle during night driving and a signaling function for notifying other vehicles and road users of the driving state of the vehicle.
[0003] For example, mainly, a headlamp (headlight or headlamp) and a fog lamp for the purpose of lighting function, and a turn signal lamp, a tail lamp, a brake lamp, a side marker, etc. for the purpose of signaling function are provided, and such vehicle lamps are regulated by laws regarding their installation standards and specifications so as to fully exhibit each function. Recently, in addition to means for irradiating the lighting of vehicle lamps or means for notifying signals externally, differentiation of the design elements of lamps has also been emphasized. Therefore, the development of vehicle lamps equipped with various matrix-shaped light sources has been carried out.
[0004] However, conventionally, since vehicle lamps form a static lamp image using a light source installed in a fixed structure, there is a limit in expressing various designs with the distributed image. Therefore, in addition to realizing a static lamp image by simply lighting the light source, there is a situation where technological improvement is required so that various lamp images can be realized to give a visually improved effect in terms of design.

[0028] Referring to FIGS. 1 to 9, a vehicle lamp 10 according to an embodiment of the present invention 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.
[0029] The first optical module 110 is provided to form a first light distribution pattern with the light emitted from the first light source part 111.
[0030] Specifically, the first optical module 110 can include a first light source unit 111, and the first light source unit 111 can include a first substrate and a plurality of first light sources mounted on the first substrate. For example, the first light source can be provided as a light emitting diode (hereinafter referred to as LED), a micro LED, etc., and the first substrate can be provided as a printed circuit board (PCB).
[0031] For example, the first substrate can be formed in a plate shape, the first light sources can be in a matrix form, and can be arranged in a plurality along rows and columns on the first substrate. However, it is not limited thereto, and the first light sources may be irregularly arranged on the first substrate. One or two or more first light sources can constitute individual unit pixels. The first light sources can be turned on or off in pixel units, or the brightness and color can be adjusted according to the control of a control unit (not shown). Thereby, the first light distribution pattern formed by the first optical module 110 can be output as various images having different shapes from each other, or the brightness and color can be output as various images. That is, the first light distribution pattern formed by the first optical module 110 can be converted into various images.
[0032] The second optical module 120 is provided to form a second light distribution pattern with the light irradiated from the second light source unit 121. The second optical module 120 can be provided singly or in a plurality around the first optical module 110. When a plurality of second optical modules 120 are provided, they can behave integrally. Also, the second optical module 120 can behave separately from the first optical module 110.
[0033] Specifically, the second optical module 120 can include a second light source unit 121, and the second light source unit 121 can include a second substrate and a second light source. The second light source unit 121 can be formed in the same configuration and structure as that of the first light source unit 111 described above. Specifically, the second light sources can be arranged on the second substrate in a matrix form, and one or more of the second light sources can constitute individual unit pixels. The second light sources can be turned on or off in pixel units, or the brightness and color can be adjusted according to the control of the control unit. Thereby, the second light distribution pattern formed by the second optical module 120 can be converted into various images.
[0034] The third optical module 130 is provided to form a third light distribution pattern with the light irradiated from the third light source unit 131. Here, the light irradiated by the third light source unit 131 is configured to be emitted to the outside in a state where the first light source unit 111 is moved by the moving unit 200 and the second light source unit 121 is rotated by the link unit 300. That is, the third optical module 130 can be provided to irradiate light to the outside by the dynamic conversion of the first optical module 110 and the second optical module 120.
[0035] Here, the first optical module 110, the second optical module 120, and the third optical module 130 can be provided to be individually turned on or off.
[0036] The moving unit 200 is connected to the first light source unit 111 and is provided to move the first light source unit 111. Specifically, the moving unit 200 can be coupled to the first light source unit 111 and can linearly move the first light source unit 111. Thereby, the first light distribution pattern can realize a three-dimensional image.
[0037] The link unit 300 is connected to the second light source unit 121 and is provided to rotate the second light source unit 121 in conjunction with the moving unit 200.
[0038] Specifically, the link part 300 is configured to rotate the second light source part 121, is connected to the moving part 200, and can be coupled to the second light source part 121. When the moving part 200 operates to move the first light source part 111, the link part 300 can be provided to rotate the second light source part 121 in conjunction with this.
[0039] The drive part 400 can provide a driving force to the moving part 200 and the link part 300.
[0040] Specifically, the drive part 400 is connected to the moving part 200 and can move the moving part 200 forward or backward. Also, when the moving part 200 moves, the drive part 400 can operate the link part 300 in conjunction with this. Thereby, the drive part 400 can move the first optical module 110 and rotate the second optical module 120.
[0041] When the dynamic conversion of the first optical module 110 and the second optical module 120 is performed by the drive part 400, thereby, the light irradiated to the third light source part 131 can be provided to be irradiated to the outside. That is, the third light distribution pattern by the third optical module 130 can be provided to be included in the lamp image of the vehicle lamp according to the present invention in a state where the first light source part 111 moves and the second light source part 121 rotates. At this time, by adding the light by the third light source part 131, the total amount of light irradiated by the vehicle lamp 10 can be increased.
[0042] The lamp image, which is the overall beam pattern formed by the first light distribution pattern, the second light distribution pattern, and the third light distribution pattern as described above, can be provided so as to be converted by the moving part 200 and the link part 300. For example, each optical module can be individually turned on and off as described above. 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. Also, when the moving part 200 and the link part 300 are driven, the overall lamp image can be realized by the first light distribution pattern and the third light distribution pattern, or can be realized by the first to third light distribution patterns.
[0043] According to the vehicle lamp 10 according to an embodiment of the present invention, the image of the overall light distribution pattern can be three-dimensionally and dynamically converted by the moving part 200 and the driving part 400, whereby lamp images of various designs can be realized.
[0044] Also, according to the present invention, by adjusting the positions of the first optical module 110 and the second optical module 120, the light from the second optical module 120 can be added and the overall light amount can be increased. Thereby, particularly in bad weather, visibility is improved and vehicle stability can be ensured.
[0045] Also, according to the present invention, since the moving part 200 and the link part 300 are provided so as to be interlocked by one driving part 400, the driving part 400 can be minimized, the cost can be reduced, and the volume and weight can be decreased.
[0046] On the other hand, the present invention can further include a fourth optical module 140. The fourth optical module 140 forms a fourth light distribution pattern with the light emitted from the fourth light source part 141 and can be arranged in a plurality around the periphery of the first optical module 110.
[0047] Specifically, the fourth optical module 140 can include a fourth light source unit 141, and the fourth light source unit 141 can include a fourth substrate and a plurality of fourth light sources mounted on the fourth substrate. For example, the fourth light sources can be arranged in a matrix form along rows and columns on the fourth substrate. One or more than two fourth light sources can form individual pixels. The fourth light sources can be turned on or off, or their brightness and color can be adjusted in pixel units. Thereby, the fourth light distribution pattern formed by the fourth optical module 140 can be converted into various images.
[0048] For example, the fourth optical module 140 can be arranged at the periphery of the first optical module 110, and at this time, it can be arranged between adjacent second light source modules. Also, the fourth optical module 140 can be provided to maintain a static state without its position being adjusted when the moving part 200 and the link part 300 are driven, but it is not limited thereto.
[0049] The lamp image, which is the overall beam pattern formed by the vehicle lamp 10 according to the embodiment of the present invention, can be roughly divided into a first mode image formed before the moving part 200 and the link part 300 operate, and a second mode image formed when the moving part 200 and the link part 300 operate.
[0050] The first mode image can be formed including the first light distribution pattern and the second light distribution pattern in an initial state. Also, the first mode image can further include the fourth light distribution pattern.
[0051] 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 have not changed. As described above, the first light source unit 111 and the second light source unit 121 can be formed such that the first light source and the second light source are arranged on the substrate in a matrix form and can be converted into various images even in a static state. The first-mode image can be an image by the ordinary vehicle lamp 10 and can be provided so as to be converted into various images by one vehicle lamp 10.
[0052] The second-mode image can be formed to include a first light distribution pattern, a second light distribution pattern, and a third light distribution pattern in a state where the first light source unit 111 moves and the second light source unit 121 rotates. Also, the second-mode image can include a fourth light distribution pattern.
[0053] Specifically, the second-mode image is an image in a state where the positions of the first optical module 110 and the second optical module 120 have changed. The second-mode image can be realized as a three-dimensional image by the operations of the first optical module 110 and the second optical module 120, and the light amount can be increased by adding the third optical module 130. Thereby, it can be provided so as to be realized when various images are required or in bad weather such as rainy days and thick fog.
[0054] On the other hand, hereinafter, the specific configurations of the moving unit 200, the link unit 300, and the driving unit 400 will be described. For reference, the first to fourth optical modules are illustrated in FIGS. 1, 2, 7 to 9, and the first optical module, the second optical module, and the fourth optical module are omitted in FIGS. 3, 5, and 6.
[0055] For example, the drive unit 400 can be provided as an actuator. The drive unit 400 includes a housing 410, a drive motor (not shown) provided inside the housing 410, a screw rod that rotates upon receiving the transmission of the driving force of the drive motor, and a drive shaft 420 that is connected to the screw rod and is provided to move forward or backward when the screw rod rotates. Thereby, the drive shaft 420 can be provided to move forward or backward by protruding from and retracting into the housing 410 by the driving force of the drive motor.
[0056] The moving unit 200 can include a moving rod 210, a main bezel 220, and a moving plate 230.
[0057] The moving rod 210 extends along the central axis of the drive shaft 420, and one end portion in the longitudinal direction can be coupled to the drive shaft 420 and can be provided to move together with the drive shaft 420.
[0058] Specifically, the moving rod 210 can be formed in a rod shape, and the lower end portion (with reference to the vertical direction in the drawing) facing the drive unit 400 can be fixed to the upper end portion of the drive shaft 420. When the drive shaft 420 protrudes from and retracts into the housing 410 to move forward or backward, the moving rod 210 can move in conjunction with the movement of the drive shaft 420.
[0059] For example, the moving unit 200 can further include a retainer 250 and a retainer holder 251. The retainer holder 251 can be provided at the lower end portion of the moving rod 210, and the retainer 250 can be provided between the retainer holder 251 and the drive shaft 420 and can rotationally support the drive shaft 420 that moves forward and backward while rotating.
[0060] The main bezel 220 can have the first light source unit 111 installed thereon and can be fixed to the other end portion in the longitudinal direction of the moving rod 210.
[0061] Specifically, the main bezel 220 is a member for linearly moving the first light source unit 111 and can be fixed to the upper end portion (with reference to the drawing direction) of the moving rod 210. For example, the main bezel 220 can be formed in a plate shape and can be provided perpendicular to the moving rod 210. The first light source unit 111 can be installed on the surface of the main bezel 220 facing forward. By moving the main bezel 220, the first optical module 110 can perform dynamic image conversion.
[0062] The moving plate 230 is fixed to the moving rod 210 and can be provided at a distance from the main bezel 220. For example, the moving plate 230 can be formed in a plate shape and can be provided parallel to the main bezel 220, but is not limited thereto. Components of the third optical module 130 can be mounted on the moving plate 230.
[0063] On the other hand, the vehicle lamp 10 according to the present invention can further include a base plate 500. The base plate 500 is mounted on a lamp housing (not shown) and can serve to support the link portion 300.
[0064] The base plate 500 can include a main body 510, a hinge coupling portion 520, and a link through hole 540.
[0065] The main body 510 is a portion forming the main body of the base plate 500, and a through hole 511 can be formed so that the moving rod 210 passes through. That is, the main body 510 can be formed in a ring shape.
[0066] The hinge joint portion 520 is formed on the main body 510 and can be provided in plural along the periphery of the through hole 511. The link through hole 540 can penetrate the main body 510 and be formed at a position corresponding to the hinge joint portion 520. For example, the hinge joint portion 520 can protrude upward from the main body 510, and the link through hole 540 can be formed so as to penetrate the front and rear surfaces of the main body 510. The hinge joint portion 520 and the link through hole 540 can be formed in the number corresponding to the second optical module 120.
[0067] The link portion 300 can include a rotary bezel 310, a first link member 320, a second link member 330, and a link holder 340.
[0068] The rotary bezel 310 has the second light source unit 121 mounted thereon, is hinge-coupled to the hinge joint portion 520, and can be rotatably mounted on the base plate 500. The rotary bezel 310 can be provided at the position and in the number corresponding to the second optical module 120, and the second light source unit 121 can be mounted on the surface facing forward which is the light irradiation direction. On the rotary bezel 310, hinge protrusions rotatably connected to the hinge joint portion 520 are formed, and the rotary bezel 310 can rotate about the hinge joint portion 520.
[0069] The first link member 320 is rotatably connected to the rotary bezel 310 and can be provided so as to penetrate the link through hole 540. The second link member 330 can be rotatably connected to the first link member 320. The link holder 340 can be movably penetrated by the moving rod 210 and can be rotatably coupled to the second link member 330 (see FIG. 7). Here, the first link member 320 and the second link member 330 can be provided in the number corresponding to the number of the rotary bezels 310.
[0070] Specifically, the second link member 330 can be connected to the moving rod 210 via the link holder 340. The link holder 340 can be slidably connected to the moving rod 210. When the moving rod 210 moves, the link holder 340 does not move together but can be pressurized by the drive shaft 420 and move when the moving rod 210 moves. When the link holder 340 moves, the second link member 330 can rotate (see FIG. 8).
[0071] The first link member 320 can be rotatably connected to the second link member 330 via a rotating pin or the like, and when the second link member 330 rotates, it can rotate about the rotating pin in conjunction therewith. When the first link member 320 rotates, it can advance forward of the base plate 500 through the link through-hole 540. At this time, the first link member 320 can pressurize the rotating bezel 310. The rotating bezel 310 is pressurized by the first link member 320 and rotates about the hinge joint portion 520 (see FIG. 9). Through such a process, the movement of the moving part 200 and the rotational movement of the link part 300 can be interlocked.
[0072] Here, an inclined surface 541 can be formed on the surface of the link through-hole 540 facing the through-hole 511. The inclined surface 541 can be inclined at a predetermined angle on the inner surface facing the through-hole 511 so as to limit the rotation angle of the first link member 320. Specifically, referring to FIG. 9, when the first link member 320 rotates, it can contact the inclined surface 541, and the first link member 320 can be inclined toward the central axis by an angle corresponding to the angle of the inclined surface 541. In this way, the rotation angles of the first link member 320 and the rotating bezel 310 can be limited by the angle of the inclined surface 541 of the link through-hole 540.
[0073] A pressing tool 430 can be formed at the end of the drive shaft 420. The pressing tool 430 can be provided such that the end of the moving rod 210 is coupled thereto, and when the moving rod 210 moves, the link holder 340 is pressed by the first link member 320 and the second link member 330 so that the rotary bezel 310 rotates.
[0074] Specifically, the pressing tool 430 can be formed to have a diameter larger than that of the moving rod 210, and after moving together with the moving rod 210, it can contact the link holder 340 and press the link holder 340 in the moving direction.
[0075] A plurality of rotary bezels 310 are provided along the periphery of the main bezel 220, and can be provided such that the rotation angle is variable by the drive unit 400. As described above, the maximum rotation angle of the rotary bezel 310 can be limited by the link through-hole 540 in the base plate 500. Also, the degree of rotation of the rotary bezel 310 can be adjusted according to the degree of the driving force of the drive unit 400, that is, the degree to which the pressing tool 430 presses the link holder 340. Thereby, the degree of image conversion and the emission amount of the third light source unit 131 can be adjusted.
[0076] The third light source unit 131 can be installed on the rear surface, which is the surface facing the moving plate 230 of the main bezel 220. That is, the first light source unit 111 can be installed on the front surface of the main bezel 220, and the third light source unit 131 can be installed on the rear surface of the main bezel 220.
[0077] Also, the third optical module 130 can further include a reflection part 132. The reflection part 132 is installed on the moving plate 230 and can be provided to reflect the light irradiated from the third light source unit 131. For example, the shape of the reflection part 132 can be formed in a curved surface shape so as to curve in the direction facing the moving plate 230, but the shape of the reflection part 132 is not limited thereto.
[0078] Also, the light reflected through the reflection part 132 can be configured to be reflected through the rotating bezel 310. Here, the rotating bezel 310 can be coated with a reflective material so as to reflect the light reflected by the reflection part 132 to the outside. Here, the reflective material can be provided as aluminum or the like that can reflect light.
[0079] For example, the rotating bezel 310 can have a reflective material vapor-deposited on its rear surface, and the rotating bezel 310 and the second substrate can be made of a light-transmissive material. Thereby, the light irradiated from the third light source unit 131 can pass through the second light source unit 121 and be reflected by the rotating bezel 310. A space can be formed between the rotating bezel 310 and the main bezel 220 due to the rotation of the rotating bezel 310 and the movement of the main bezel 220, and the light reflected by the rotating bezel 310 can be irradiated forward through the said space. Also, a reflective material can be coated on the rear surface, which is the surface facing the reflection part 132 of the main bezel 220. Thereby, the light irradiated from the third light source unit 131 and the light irradiated to the main bezel 220 through the reflection part 132 can be re-reflected by the reflection part 132.
[0080] On the other hand, an embodiment of the present invention can further include a sub-bezel 600 to which the fourth optical module 140 is attached. Also, the base plate 500 can be disposed between adjacent hinge coupling parts 520 and further include a bezel fixing part 530 to which the sub-bezel 600 is fixed.
[0081] That is, the bezel fixing part 530 can be formed corresponding to the position of the sub-bezel 600 and can be fastened to the sub-bezel 600 by bolt connection or the like. Thereby, the sub-bezel 600 and the fourth optical module 140 coupled thereto may not undergo mechanical conversions such as rotation or movement. However, as described above, the fourth optical module 140 can perform image conversion in a static state.
[0082] Thus, according to an embodiment of the present invention, the vehicle lamp can stereoscopically and dynamically convert the image of the overall light distribution pattern by the moving part and the driving part, whereby lamp images of various designs can be realized.
[0083] Also, according to the present invention, by adjusting the positions of the first optical module and the second optical module, light from the third optical module can be added, and the overall light amount can be increased. Thereby, particularly in bad weather, visibility is improved and vehicle stability can be ensured.
[0084] Moreover, according to the present invention, by providing the moving part and the link part to be interlocked by one driving part, the driving part can be minimized, the cost can be reduced, and the volume and weight can be decreased.
[0085] As described above, specific embodiments of the present invention have been described in detail. However, the idea and scope of the present invention are not limited to such specific embodiments, and various modifications and variations can be made by those having ordinary knowledge in the technical field to which the present invention pertains without changing the gist of the present invention described in the claims.
