Description

Technical Field

[0001] This utility model relates to a vehicle lighting fixture, and more specifically, to a vehicle lighting fixture capable of forming multiple and dynamic images. Background Technology

[0002] Typically, vehicles are equipped with a variety of lights that provide illumination for easy identification of objects around the vehicle when driving at night, as well as signals to inform surrounding vehicles or pedestrians of the vehicle's driving status.

[0003] For example, headlights and fog lights mainly serve an illumination function, while turn signals, taillights, and brake lights mainly serve a signaling function. The setting standards and specifications of each light fixture are stipulated by regulations to ensure that each function is fully utilized.

[0004] Recently, since lighting and signaling functions alone can only provide limited information, research is actively underway on lamps that can provide a variety of information by equipping them with images such as text or patterns that are formed on the road surface around the vehicle, in addition to lamps used for lighting and signaling functions.

[0009] In addition, a vehicle lamp that can generate both static and dynamic images is provided.

[0010] The technical problems of this utility model are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned from the following description.

[0011] To address the aforementioned technical issues, a vehicle lamp according to an embodiment of the present invention may include: a light source unit comprising a plurality of light sources; a light path adjustment unit for adjusting the path of light emitted from at least one of the plurality of light sources; and an optical lens unit comprising a plurality of incident lenses for incident light emitted from the light path adjustment unit and a plurality of exiting lenses for emitting light incident on the plurality of incident lenses, wherein the light path adjustment unit may include: a plurality of adjustment lenses for adjusting the path of light emitted from each of the plurality of light sources.

[0012] The optical lens section may further include: a plurality of shielding members located between the plurality of incident lenses and the plurality of exiting lenses to block a portion of the light traveling toward each of the plurality of exiting lenses.

[0013] The optical lens section can be divided into multiple lens regions corresponding to each of the plurality of light sources, and light transmitted through at least one of the plurality of lens regions can form at least one image on the surface illuminated by the light.

[0014] Any one of the multiple images formed by light transmitted through each of the multiple lens regions can have image properties different from each other.

[0015] The image attributes may include at least one of the following: image shape, formation location, brightness, size, and color.

[0016] At least one of the plurality of lens regions may include a plurality of transmission regions, wherein the sub-image formed by light transmitted through each of the plurality of transmission regions may have different image properties from each other.

[0017] The proportion in which each of the plurality of transmission regions occupies the corresponding lens region in the plurality of lens regions may be different from each other.

[0018] The sub-image formed by any one of the multiple transmission regions and the sub-image formed by another transmission region can be formed at positions different from each other from the optical lens.

[0019] In the plurality of transmission regions, the size of the transmission region in which the sub-image is formed at a position closer to the optical lens can be smaller than the size of the transmission region in which the sub-image is formed at a position farther from the optical lens.

Figure 3 This is a front view showing a vehicle lamp according to an embodiment of the present invention. Figure 4 This is a side view showing a vehicle lamp according to an embodiment of the present invention. Figure 5 and Figure 6 This is an exploded perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 7 yes Figure 3 A-A' profile.

[0054] Reference Figures 1 to 7 According to an embodiment of the present invention, a vehicle lamp 1 may include a light source 1000, a light path adjustment 2000, and an optical lens 3000.

[0055] In the embodiments of this utility model, the example is given where the vehicle lamp 1 is used to form an image on the road surface around the vehicle to indicate various information that needs to be communicated to surrounding vehicles or pedestrians, including the driver. However, this is not the case. In addition to being used for lighting or signaling functions, the vehicle lamp 1 of this utility model can also be used as an interior lamp installed inside the vehicle.

[0056] For example, the vehicle lamp 1 of this utility model can form an image on the road surface around the vehicle for a welcoming function when the driver approaches the vehicle, so that the vehicle shows a welcoming response to the driver, and can also form an image on the road surface around the vehicle to inform surrounding vehicles or pedestrians of the vehicle's status such as the vehicle's driving direction, deceleration, opening doors, etc.

[0057] The vehicle light fixture 1 of this utility model can be installed in various locations that easily form an image on the road surface around the vehicle, such as the exterior rearview mirror, door sill, front of the vehicle, and rear of the vehicle. Figure 4 As shown, the example is set to tilt downwards at a predetermined angle θ towards the road surface surrounding the vehicle, with the up-down direction as the reference. However, this is only an example to help understand the present invention and is not limited thereto. The position and angle of the vehicle lamp 1 of the present invention, which is used to form an image on the road surface surrounding the vehicle, can be changed in various ways.

[0058] In the following embodiments of the present invention, an example is given of forming an image by illuminating light onto the road surface surrounding the vehicle. However, this is only an example to help understand the present invention and is not limited thereto. According to the purpose of the vehicle lamp 1 of the present invention, the surface that forms an image by illuminating light can be at least one of the surfaces located inside and outside the vehicle.

[0059] The light source unit 1000 may include a plurality of light sources 1210, 1220, 1230, and 1240 disposed on the front surface of the substrate 1100, and the image formed by light emitted from each of the plurality of light sources 1210, 1220, 1230, and 1240 may have the same or different image properties from each other.

[0060] In the embodiments of this utility model, the case of using semiconductor light-emitting elements such as light-emitting diodes (LEDs) as multiple light sources 1210, 1220, 1230, and 1240 is described as an example, but it is not limited to this. The multiple light sources 1210, 1220, 1230, and 1240 can not only use LEDs, but also various light sources such as laser diodes (LDs) or bulbs. Furthermore, depending on the type of light source, optical elements such as reflectors, phosphors, mirrors, prisms, and lenses for adjusting the path and brightness of light can be further used.

[0061] At this time, the image attributes may include at least one of the image's shape, formation location, brightness, size, and color, and the image attributes that are different from each other, formed by light emitted from one of the plurality of light sources 1210, 1220, 1230, 1240 and formed by light emitted from the other, can be understood as the image's shape, formation location, brightness, size, and color being different from each other.

[0062] Furthermore, when the light source unit 1000 includes multiple light sources 1210, 1220, 1230, and 1240, the lighting sequence, lighting interval, lighting time, etc. of each of the multiple light sources 1210, 1220, 1230, and 1240 can be controlled individually. This allows not only static images but also dynamic images such as animation effects to be realized. A detailed explanation of this will be provided later.

[0063] In the embodiments of this utility model, the case where the light source unit 1000 includes four light sources 1210, 1220, 1230, and 1240 is merely an example to help understand this utility model and is not limited thereto. The number of light sources included in the light source unit 1000 may vary depending on the number of images formed by the vehicle lamp 1 of this utility model.

[0064] The aforementioned light source unit 1000 may not only have multiple light sources 1210, 1220, 1230, and 1240 provided on the substrate 1100, but may also have various components such as connectors (not shown) for power supply or operation control of the multiple light sources 1210, 1220, 1230, and 1240.

[0065] The optical path adjustment unit 2000 can be located in front of the light source unit 1000 to adjust the path of light so that the light emitted from the light source unit 1000 can be incident on the optical lens unit 3000 located in front of the optical path adjustment unit 2000 with as little loss as possible.

[0066] At this time, the multiple light sources 1210, 1220, 1230, and 1240 can be configured such that the light-emitting surface faces forward so that light is incident on the light path adjustment unit 2000 located in front of the light source unit 1000.

[0067] The fact that the light path adjustment unit 2000 is located in front of the light source unit 1000 and the optical lens unit 3000 is located in front of the light path adjustment unit 2000 means that the direction in which the light is irradiated from the vehicle lamp 1 of this utility model is forward. Depending on the position or direction of the vehicle lamp 1 of this utility model, the actual direction in front can be changed.

[0068] The optical path adjustment unit 2000 may include: a lens unit 2100, including a plurality of adjustment lenses 2111, 2112, 2113, and 2114 corresponding to each of the plurality of light sources 1210, 1220, 1230, and 1240; and a guide unit 2200, which guides the light emitted from each of the plurality of light sources 1210, 1220, 1230, and 1240 to travel separately from each other as they travel to the optical lens unit 3000, so as to prevent interference between them. The optical path adjustment unit 2000 can be understood as an assembly formed by assembling the lens unit 2100 and the guide unit 2200.

[0069] Figure 8 This is a front view showing the lens portion according to an embodiment of the present invention. Figure 9 This is a rear view showing the lens portion according to an embodiment of the present invention.

[0070] Reference Figure 8 and Figure 9 According to an embodiment of the present invention, the lens section 2100 may include a plurality of adjustment lenses 2111, 2112, 2113, 2114 and a lens plate 2120.

[0071] Each of the plurality of adjustment lenses 2111, 2112, 2113, and 2114 is arranged to be spaced apart from each other on the lens plate 2120 at a predetermined interval, corresponding to the position of each of the plurality of light sources 1210, 1220, 1230, and 1240, thereby serving to focus the light emitted from the corresponding light source among the plurality of light sources 1210, 1220, 1230, and 1240. In the embodiment of this utility model, since the light source unit 1000 includes four light sources 1210, 1220, 1230, and 1240, the case in which the lens unit 2100 includes four adjustment lenses 2111, 2112, 2113, and 2114 is described as an example, but it is not limited to this, and the number of adjustment lenses can be changed according to the number of light sources.

[0072] The example described is an aspherical lens used in which light emitted and incident from the corresponding light source among the multiple light sources 1210, 1220, 1230, and 1240 is converted into approximately parallel light. However, this is not a limitation. The multiple adjustment lenses 2111, 2112, 2113, and 2114 can be not only aspherical lenses, but also various lenses that can convert light into approximately parallel light, such as total internal reflection (TIR) ​​lenses and Fresnel lenses.

[0073] Multiple adjustment lenses 2111, 2112, 2113, and 2114 can be integrated together by means of lens plate 2120. Therefore, compared with the case of assembling each of the multiple adjustment lenses 2111, 2112, 2113, and 2114 separately, the number of parts can be reduced and the assembly process can be simplified.

[0074] At this time, the situation where the plurality of adjustment lenses 2111, 2112, 2113, and 2114 are formed as one unit can include not only the situation where the lens plate 2120 and the plurality of adjustment lenses 2111, 2112, 2113, and 2114 are manufactured as one unit, but also the situation where the plurality of adjustment lenses 2111, 2112, 2113, and 2114 and the lens plate 2120 are manufactured separately and combined with each other in a manner in which there is no relative movement with the lens plate 2120.

[0075] The lens plate 2120 can be formed such that at least one protrusion 2121 protrudes toward the light source 1000 on the surface facing the light source 1000, and the at least one protrusion 2121 can be configured such that each of the plurality of light sources 1210, 1220, 1230, 1240 is separated from the corresponding adjustment lens of the plurality of adjustment lenses 2111, 2112, 2113, 2114 by a predetermined interval, thereby preventing structural interference between them.

[0076] At this time, the lens plate 2120 can be formed asymmetrically in at least one direction, so that the assembly position can be easily confirmed during the assembly of the lens part 2100 to prevent incorrect assembly.

[0077] The above Figure 8 and Figure 9 This is an example of a lens plate 2120 being formed in a generally rhomboid shape, and being formed symmetrically in the left-right direction and asymmetrically in the up-down direction.

[0078] Figure 10 This is a front view showing the guide portion according to an embodiment of the present invention. Figure 11 This is a rear view showing the guide portion according to an embodiment of the present invention.

[0079] Reference Figure 10 and Figure 11 According to an embodiment of the present invention, the guide portion 2200 can be assembled with the lens portion 2100 and includes a plurality of through holes 2221, 2222, 2223, 2224 formed by the partition wall 2210, to prevent light emitted from each of the plurality of light sources 1210, 1220, 1230, 1240 from interfering with each other as the light travels in parallel through the corresponding adjustment lenses of the plurality of adjustment lenses 2111, 2112, 2113, 2114 into the optical lens portion 3000.

[0080] At this time, the partition wall 2210 can be connected between the two opposite ends in the hollow frame 2230, and the multiple through holes 2221, 2222, 2223, 2224 can be separated from each other by the partition wall 2210 and the frame 2230.

[0081] In the embodiments of this utility model, since the lens part 2100 includes four adjustment lenses 2111, 2112, 2113, and 2114, the case in which the partition wall 2210 is formed in a generally "+" shape to form four through holes 2221, 2222, 2223, and 2224 within the closed curve frame 2230 is described as an example. However, it is not limited to this, and the shape of the partition wall 2210 connection can be varied depending on the number and position of the through holes formed in the guide part 2200.

[0082] The guide portion 2200 may include at least one assembly groove 2240 into which at least one assembly protrusion 2122 formed on the lens plate 2120 is inserted. With at least one assembly protrusion 2122 inserted into at least one assembly groove 2240, at least one assembly protrusion 2122 and at least one assembly groove 2240 are fixed to each other by means of heat welding or the like, so that the lens portion 2100 and the guide portion 2200 can be modularized. If the lens portion 2100 and the guide portion 2200 constituting the optical path adjustment portion 2000 can be modularized before the vehicle lamp 1 of this utility model is assembled, the lens portion 2100 and the guide portion 2200 can be assembled simultaneously by one assembly process, thereby simplifying the entire assembly process.

[0083] In the embodiments of this utility model, the case in which at least one assembly protrusion 2122 is formed in the lens plate 2120 and at least one assembly groove 2240 is formed in the guide portion 2200 is described as an example, but it is not limited to this, and vice versa.

[0084] Additionally, the lens portion 2100 may include at least one through hole 2123, which is formed in the lens plate 2120 between adjacent adjustment lenses among the plurality of adjustment lenses 2111, 2112, 2113, 2114. The guide portion 2200 may have at least one extension portion 2211 extending from the partition wall 2210 toward the light source portion 1000. Since the end of the at least one extension portion 2211 passes through at least one through hole 2123 and is located between adjacent light sources among the plurality of light sources 1210, 1220, 1230, 1240, interference can be prevented from occurring when light generated from adjacent light sources is incident on another adjustment lens adjacent to the corresponding adjustment lens among the plurality of adjustment lenses 2111, 2112, 2113, 2114.

[0085] In this embodiment of the present invention, an example will be given of a case in which interference is avoided when at least one extension 2211 is arranged through at least one through hole 2123 and the size of at least one extension 2211 is smaller than the size of the partition wall 2210 so that more than two extensions can be formed in the partition wall 2210.

[0086] Figure 12 This is a front view showing the optical path adjustment part according to an embodiment of the present invention. Figure 13 This is a rear view showing the optical path adjustment section according to an embodiment of the present invention. Figure 14 yes Figure 12 The cross-sectional view along line B-B'.

[0087] Reference Figures 12 to 14 As at least one assembly protrusion 2122 of the lens plate 2120 formed in the lens portion 2100 is inserted into at least one assembly groove 2240 of the guide portion 2200 located in front of the lens portion 2100, the optical path adjustment portion 2000 according to the embodiment of the present invention can insert each of the plurality of adjustment lenses 2111, 2112, 2113, 2114 into the corresponding through hole of the plurality of through holes 2221, 2222, 2223, 2224, and fix the at least one assembly protrusion 2122 and the at least one assembly groove 2240 to each other by means of fixing such as heat fusion, thereby realizing the assembly of the lens portion 2100 and the guide portion 2200.

[0088] At this time, at least one extension 2211 extending from the partition wall 2210 toward the light source section 1000 passes through at least one through hole 2123 of the lens plate 2120 and is located between adjacent light sources among the plurality of light sources 1210, 1220, 1230, 1240, thereby preventing light emitted from each of the plurality of light sources 1210, 1220, 1230, 1240 from being incident on another adjustment lens adjacent to the corresponding adjustment lens among the plurality of adjustment lenses 2111, 2112, 2113, 2114.

[0089] The aforementioned optical path adjustment unit 2000 can be assembled with the light source unit 1000 by coating the substrate 1100 with an adhesive that can be cured by ultraviolet (UV) light, and by irradiating the coated adhesive with ultraviolet (UV) light while the optical path adjustment unit 2000 is placed on the substrate 1100. However, this is only an example to help understand the present invention and is not limited thereto. The light source unit 1000 and the optical path adjustment unit 2000 can be assembled not only by adhesive but also by various other methods such as hook connection or threaded connection.

[0090] Figure 15 This is a front view showing the optical lens portion according to an embodiment of the present invention. Figure 16 This is a rear view showing the optical lens portion according to an embodiment of the present invention.

[0091] Reference Figure 15 and Figure 16 According to an embodiment of the present invention, the optical lens section 3000 can emit at least a portion of the light incident from the optical path adjustment section 2000, thereby forming at least one image on the road surface around the vehicle. The at least one image formed by the light emitted from the optical lens section 3000 can have the shape of text, pattern or a combination thereof.

[0092] The optical lens section 3000 may include a plurality of incident lenses 3100, a plurality of exit lenses 3200, and a light transmission section 3300.

[0093] Multiple incident lenses 3100 allow light emitted from the optical path adjustment unit 2000 to enter, and light incident on each of the multiple incident lenses 3100 can be emitted through the corresponding emission lens among the multiple emission lenses 3200. In the embodiments of this utility model, since the multiple incident lenses 3100 and the multiple emission lenses 3200 have relatively short focal lengths, the case of using microlenses which are conducive to miniaturization will be described as an example.

[0094] Multiple incident lenses 3100 can be located on the incident surface 3310 of the light transmission section 3300, and multiple exit lenses 3200 can be located on the exit surface 3320 of the light transmission section 3300. The light transmission section 3300 is formed using a light-transmitting material such as glass, so that light incident on the multiple incident lenses 3100 can be emitted through the light transmission section 3300 and the multiple exit lenses 3200.

[0095] The optical lens section 3000 may further include: a plurality of shielding members (not shown) located between the incident surface 3310 and the emission surface 3320 of the light transmission section 3300 and respectively including a region for transmitting light and a region for blocking light, so as to block a portion of the light traveling toward the corresponding emission lens among the plurality of emission lenses 3200, and the light transmission section 3300 may be constructed using a plurality of light transmission components, such that the plurality of shielding members are disposed between the incident surface 3310 and the emission surface 3320 of the light transmission section 3300.

[0096] Each of the plurality of shielding elements can be modified in terms of the shape or size of the area transmitting light and the area blocking light, depending on the shape or size of the image of the road surface formed by the vehicle lamp 1 of this invention around the vehicle.

[0097] At this time, when the light source unit 1000 is assembled in the housing 4000, the end of the partition wall 2210 of the light path adjustment unit 2000 facing the optical lens unit 3000 can be configured to contact the incident surface 3310 of the optical lens unit 3000, that is, to contact the incident surface 3310 of the light transmission unit 3300, so as to apply pressure to the optical lens unit 3000. In this way, the position of the optical lens unit 3000 can be fixed and the optical lens unit 3000 can be prevented from moving.

[0098] In the embodiments of this utility model, the example is given in which multiple incident lenses 3100 are uniformly formed on the incident surface 3310 of the light transmission section 3300. However, it is not limited to this. Incident lenses can be formed in the area of ​​the incident surface 3310 of the light transmission section 3300 that contacts the end of the partition wall 2210, thereby preventing structural interference or damage.

[0099] The aforementioned light source 1000, optical path adjustment 2000, and optical lens 3000 can be located inside a housing 4000 with one side open. A housing cover 5000 can be provided on the open side of the housing 4000 to fix the positions of the components 1000, 2000, and 3000 located inside the housing 4000, thereby preventing them from falling out of their correct positions.

[0100] The housing 4000 may have an opening 4100 that allows light emitted from the optical lens section 3000 to pass through and form an image on the road surface around the vehicle. A cover lens 4200 made of a material that allows light emitted from the optical lens section 3000 to pass through may be provided in the opening 4100. The cover lens 4200 may also serve a protective function to prevent foreign objects from flowing into the housing 4000 from the outside and causing contamination or damage.

[0101] Additionally, a heat dissipation portion 1300 may be provided on the back side of the substrate 1100 to quickly release the heat generated when light is emitted from multiple light sources 1210, 1220, 1230, and 1240. To improve heat dissipation performance, a release hole 5100 may be formed in the housing cover 5000 to expose the heat dissipation portion 1300 to the outside. The housing cover 5000 may include not only the release hole 5100 but also a connection hole 5200 for connecting the power supply or operation control wire of the vehicle lamp 1 of this invention to the substrate 1100.

[0102] In addition, in embodiments of this utility model, the optical lens section 3000 can be divided into multiple lens regions A1, A2, A3, A4, and each of the multiple lens regions A1, A2, A3, A4 can serve to transmit at least a portion of the light emitted from the corresponding light source among the multiple light sources 1210, 1220, 1230, 1240, thereby forming at least one image on the road surface around the vehicle.

[0103] At this time, the multiple images formed by transmitting light through each of the multiple lens regions A1, A2, A3, A4 can have different image properties from each other. The fact that the multiple images have different image properties can be understood as at least one of the following being different: shape, formation position, brightness, size, and color. Therefore, since multiple images with different image properties can be formed by a single optical lens unit 3000, the constituent elements used to form multiple images with different image properties can be shared, thereby simplifying the structure and reducing costs.

[0104] Furthermore, at least one of the multiple lens regions A1, A2, A3, A4 can be divided into multiple transmission regions, and the multiple transmission regions can serve to form multiple sub-images of corresponding images in the multiple images, and the multiple sub-images constituting each of the multiple images can have the same or different image attributes.

[0105] In the following embodiments of the present invention, an example is given where each of the multiple images has multiple sub-images with different image attributes. As an example, any one of the multiple sub-images of each of the multiple images can be composed of text, and another sub-image can be composed of a pattern, but it is not limited to this. At least one of the shape, formation position, brightness, size, and color of the multiple sub-images can be different.

[0106] In an embodiment of this utility model, an example is given where each of the multiple lens regions A1, A2, A3, and A4 is constructed using the same number of transmission regions. In this case, each of the multiple images can be constructed using the same number of multiple sub-images, and the multiple images having different image properties can be understood as at least one of the multiple sub-images constituting each of the multiple images having different properties.

[0107] At this point, the scenario where each of the multiple lens regions A1, A2, A3, and A4 can be constructed using the same number of transmission regions is merely an example to aid in understanding the present invention and is not limited thereto. Depending on the properties of the image formed by each of the multiple lens regions A1, A2, A3, and A4, the number of transmission regions constituting each of the multiple lens regions A1, A2, A3, and A4 can be varied.

[0108] In the embodiments of this utility model, since the multiple light sources 1210, 1220, 1230, and 1240 include four light sources, the multiple lens regions A1, A2, A3, and A4 include four lens regions. Taking the case where each of the multiple lens regions A1, A2, A3, and A4 includes two transmission regions as an example, the multiple lens regions A1, A2, A3, and A4 are referred to as the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4. The image formed by the light transmitted through each of the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4 is referred to as the first image, the second image, the third image, and the fourth image.

[0109] Furthermore, in the embodiments of this utility model, the two transmission regions included in each of the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4 are collectively referred to as the first transmission region and the second transmission region, and the sub-images formed by light transmitted through the first transmission region and the second transmission region are collectively referred to as the first sub-image and the second sub-image.

[0110] The first lens region A1 may include a first transmission region A11 and a second transmission region A12. The first sub-image formed by the first transmission region A11 and the second sub-image formed by the second transmission region A12 may have different image properties from each other.

[0111] At this time, within the first lens region A1, the ratio of the first transmission region A11 to the second transmission region A12 can be different from each other. This is to ensure that the first sub-image and the second sub-image formed by the first transmission region A11 and the second transmission region A12 of the first lens region A1 have uniform brightness.

[0112] For example, such as Figure 17 As shown, with the optical lens section 3000 as a reference along at least one direction, when the position where the first sub-image is formed by the first transmission region A11 of the first lens region A1 is closer than the position where the second sub-image is formed by the second transmission region A12, that is, when the area illuminated by the light transmitted through the first transmission region A11 of the first lens region A1 is closer than the area illuminated by the light transmitted through the second transmission region A12, even if the size of the first transmission region A11 in the first lens region A1 is smaller than the size of the second transmission region A12, the first sub-image and the second sub-image can have uniform brightness, thereby preventing the generation of heterogeneity due to the brightness difference between the first sub-image and the second sub-image.

[0113] In other words, since the brightness of light is inversely proportional to the square of the distance, even if the first transmission region A11 within the first lens region A1 has a smaller size than the second transmission region A12, since the first sub-image is formed closer to the vehicle lamp 1 (i.e., the optical lens section 3000) of this invention than the second sub-image, the first sub-image and the second sub-image can have uniform brightness.

[0114] In the above embodiments, the example given is that the first sub-image and the second sub-image, which are formed at different distances from the vehicle lamp 1 of the present invention, have uniform brightness, and the ratios occupied by the first transmission region A11 and the second transmission region A12 within the first lens region A1 are different. However, this is only an example to help understand the present invention and is not limited thereto. The sizes of the first transmission region A11 and the second transmission region A12 that satisfy the image attributes required by the first sub-image and the second sub-image respectively can be varied.

[0115] In addition, similar to the first lens region A1 described above, each of the second lens region A2, the third lens region A3 and the fourth lens region A4 may include the first transmission regions A21, A31, A41 and the second transmission regions A22, A32, A42.

[0116] At this time, the first transmission region of any one of the first lens regions A1, the second lens region A2, the third lens region A3, and the fourth lens region A4 can form a sub-image with image properties different from the first transmission region of the other lens region. Similarly, the second transmission region of any one of the first lens regions A1, the second lens region A2, the third lens region A3, and the fourth lens region A4 can form a sub-image with image properties different from the second transmission region of the other lens region.

[0117] Figure 18 This is a schematic diagram showing an image formed by a vehicle lamp according to an embodiment of the present invention.

[0118] Reference Figure 18 According to an embodiment of the present invention, the optical lens unit 3000 can form a first image I1, a second image I2, a third image I3, and a fourth image I4 by transmitting light from each of the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4.

[0119] At this point, the following scenario will be used as an example for explanation: Each of the first image I1, the second image I2, the third image I3, and the fourth image I4 may include a first sub-image I11, I21, I31, I41 and a second sub-image I12, I22, I32, I42 having different image attributes from each other, and the plurality of sub-images I11, I12, I21, I22, I31, I32, I41, I42 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 may be formed at different positions from each other, and the first sub-images I11, I21, I31, I41 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 are formed at a position closer to the optical lens section 3000 than the second sub-images I12, I22, I32, I42 in at least one direction.

[0120] In the embodiments of this utility model, the example given is that, in order to make the first image I1, the second image I2, the third image I3, and the fourth image I4 have different image attributes from each other, such that the positions of the multiple sub-images I11, I12, I21, I22, I31, I32, I41, and I42 formed by each of the first image I1, the second image I2, the third image I3, and the fourth image I4 are different from each other. However, this is only an example to help understand this utility model and is not limited thereto. The description that the first image I1, the second image I2, the third image I3, and the fourth image I4 have different image attributes from each other includes not only the first image I1, the second image I2, the third image I3, and the fourth image I4. 2. The multiple sub-images I11, I12, I21, I22, I31, I32, I41, I42 of each of the third image I3 and the fourth image I4 are formed in different positions, and also include cases where at least one of the shapes, sizes, brightness, and colors is different from each other. As an example, the image attributes of the first image I1, the second image I2, the third image I3, and the fourth image I4 being different from each other means that even if the multiple sub-images I11, I12, I21, I22, I31, I32, I41, I42 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 are formed in the same position, their sizes can also be different from each other.

[0121] At this time, the description that the multiple sub-images I11, I12, I21, I22, I31, I32, I41, I42 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 are formed in different positions can be understood as the positions of the centers of the sub-images being different in at least one direction.

[0122] The first image I1, the second image I2, the third image I3, and the fourth image I4 mentioned above can each provide individual information, or two or more can be combined to provide one piece of information.

[0123] In addition, Figure 18 In the diagram, the dashed lines represent the positions of the multiple sub-images I11 and I12 that constitute the first image I1, and are used to compare the positions formed by each of the second image I2, the third image I3, and the fourth image I4 with the first image I1 as a reference.

[0124] The positions formed by the first image I1, the second image I2, the third image I3, and the fourth image I4 are not limited to those described above. Figure 18 The positions of the first image I1, the second image I2, the third image I3, and the fourth image I4 can vary depending on the shape or curvature of the incident lens and the exit lens belonging to each of the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4.

[0125] The first image I1, the second image I2, the third image I3, and the fourth image I4 mentioned above can also be formed simultaneously according to the lighting order, lighting interval, lighting time, etc. of each of the multiple light sources 1210, 1220, 1230, and 1240, or they can be formed sequentially along at least one direction.

[0126] Figure 19 This is a schematic diagram showing a plurality of images sequentially formed along one direction according to an embodiment of the present invention.

[0127] Reference Figure 19 According to an embodiment of the present invention, the vehicle lamp 1 can be lit sequentially according to the lighting interval set for each of the multiple light sources 1210, 1220, 1230, and 1240 corresponding to the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4. In this case, the first image I1, the second image I2, the third image I3, and the fourth image I4 can be formed sequentially along one direction.

[0128] at this time, Figure 19 The following description illustrates the case where the first sub-images I11, I21, I31, I41 and the second sub-images I12, I22, I32, I42 of each of the first image I1, second image I2, third image I3, and fourth image I4 are formed sequentially along the same direction, that is, along the side of the vehicle away from the vehicle. However, this is only an example to help understand the present invention and is not limited thereto. The first image I1, second image I2, third image I3, and fourth image I4 can be formed sequentially along any direction, including the direction closer to the vehicle, based on the vehicle lamp 1 of the present invention or the vehicle.

[0129] In the above Figure 19 The example given is the case where the first image I1, the second image I2, the third image I3, and the fourth image I4 are formed sequentially along one direction. However, this is not the only case. The first sub-images I11, I21, I31, and I41 and the second sub-images I12, I22, I32, and I42 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 can also be formed sequentially along multiple directions that are different from each other.

[0130] Figure 20 This is a schematic diagram showing a plurality of images sequentially formed along a plurality of different directions according to an embodiment of the present invention.

[0131] Reference Figure 20According to an embodiment of the present invention, the vehicle lamp 1 can be lit sequentially according to the lighting interval set by the multiple light sources 1210, 1220, 1230, 1240 corresponding to each of the first lens region A1, the second lens region A2, the third lens region A3, and the fourth lens region A4, and the first image I1, the second image I2, the third image I3, and the fourth image I4 can be formed sequentially along multiple directions that are different from each other.

[0132] For example, the first sub-images I11, I21, I31, and I41 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 can be formed sequentially in the direction from front to rear along the front-rear direction of the vehicle. In contrast, the second sub-images I12, I22, I32, and I42 of each of the first image I1, the second image I2, the third image I3, and the fourth image I4 can be formed sequentially in the direction away from the vehicle along the side of the vehicle.

[0133] In the above Figure 19 and Figure 20 The example described above illustrates the case where each of the first image I1, second image I2, third image I3, and fourth image I4 is formed without overlapping each other. However, this is merely an example to aid in understanding the present invention and is not limited thereto. It is also possible for two or more images of the first image I1, second image I2, third image I3, and fourth image I4 to be formed in an overlapping manner. The case of two or more images of the first image I1, second image I2, third image I3, and fourth image I4 being formed in an overlapping manner can include the case where a portion of a different image of the first image I1, second image I2, third image I3, and fourth image I4 overlaps, and the case where any one image of the first image I1, second image I2, third image I3, and fourth image I4 is entirely located within the image of another.

[0134] As described above, in the vehicle lamp 1 according to the present invention, each of the plurality of lens regions A1, A2, A3, A4 of the optical lens section 3000 forms an image with different image attributes from each other. The image of each of the plurality of lens regions A1, A2, A3, A4 is composed of a plurality of sub-images with different image attributes from each other. Therefore, the constituent elements used to form images with different image attributes from each other can be shared, thereby reducing the number of parts and reducing costs.

[0135] Furthermore, in the vehicle lamp 1 according to the present invention, multiple images can be formed sequentially along one direction or multiple directions that are different from each other, so not only static images can be realized, but also dynamic images can be realized.

[0136] Those skilled in the art to which this invention pertains will understand that this invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above are exemplary in all respects and should be understood as not limiting embodiments. The scope of this invention is not limited by the foregoing detailed description, but by the claims. All modifications or variations that can be derived from the meaning, scope, and equivalent concepts of the claims should be interpreted as included within the scope of this invention.
