Description

Technical Field

[0001] The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp capable of forming an optimal light beam pattern. Background Art

[0002] Generally, a vehicle has various lamps for the purpose of an illumination function for easily recognizing objects around the vehicle during night driving and a signal function for informing surrounding vehicles or pedestrians of the driving state of the vehicle.

[0003] For example, headlamps and fog lamps mainly aim to perform an illumination function, and turn signal lamps, tail lamps, brake lamps, etc. mainly aim to perform a signal function. The installation standards and specifications of each lamp have been regulated by regulations to fully exert their respective functions.

[0004] Among them, a headlamp irradiates light in the driving direction of the vehicle to ensure the driver's forward view, and thus plays a very important role in ensuring safe driving.

[0005] A headlamp can form a low beam pattern that irradiates light downward with a cut-off line as a reference or a high beam pattern that irradiates at least a part of the light upward of the cut-off line. When irradiating light upward of the cut-off line when forming the low beam pattern, it may cause glare to the driver of a vehicle ahead. Therefore, a solution is needed to prevent irradiating light upward of the cut-off line when forming the low beam pattern.

[0006] [Prior Art Documents] [Patent Documents] Korean Patent Publication No. 10-2023-0056465 (published on Apr. 27, 2023) Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle lamp capable of forming an optimal light beam pattern by preventing light from being emitted in an unnecessary direction.

[0008] The technical problems of the present invention are not limited to the above-mentioned technical problems, and those skilled in the art can clearly understand other technical problems not mentioned from the following description.

[0009] To achieve the above technical problems, a vehicle lamp according to an embodiment of the present invention forms a predetermined light beam pattern by means of a plurality of lamp modules. Each of the plurality of lamp modules includes: a light source unit including at least one light source; an optical path conversion unit that converts the path of light emitted from the light source unit; and an optical unit that transmits at least a part of the light emitted from the optical path conversion unit to form the light beam pattern, wherein the optical unit may be inclinedly disposed in such a way that one side is more forward than the other side in at least one direction.

[0010] The light source unit can be disposed such that the optical axis is inclined in at least one direction with respect to the central axis of the optical path conversion unit.

[0011] The plurality of lamp modules can be gradually located in front from one side toward the other side in at least one direction.

[0012] The light source unit of each of the plurality of lamp modules can be disposed in a common substrate.

[0013] The common substrate can be disposed to be inclined such that one side is more in front than the other side in at least one direction.

[0014] The optical path conversion unit can include: an incident portion that allows light emitted from the light source unit to enter; and an emission portion that emits the light incident on the incident portion, wherein the light incident on the incident portion is converted into parallel light and emitted through the emission portion.

[0015] The incident portion can include: a first incident surface formed to protrude toward the light source unit; a second incident surface formed to protrude from an edge of the first incident surface toward the light source unit; and a reflection surface that reflects the light incident on the second incident surface so as to travel toward the emission portion.

[0016] The emission portion can include: a plurality of emission surfaces having different curvatures from each other.

[0017] The emission portion can include: a first emission surface formed to protrude forward; and a second emission surface formed to have a planar shape around the first emission surface, wherein the first emission surface has a greater curvature than the incident surface of the incident portion that is formed to protrude toward the light source unit.

[0018] The optical unit can include: a plurality of incident lenses; a plurality of emission lenses respectively corresponding to the plurality of incident lenses; and a plurality of shielding holes formed between the incident lenses and the emission lenses that correspond to each other among the plurality of incident lenses and the plurality of emission lenses.

[0019] The incident lenses and the emission lenses that correspond to each other among the plurality of incident lenses and the plurality of emission lenses can be formed to have different curvatures on both sides in at least one direction with respect to a reference line parallel to the front-rear direction.

[0020] The plurality of shielding holes can be formed by removing a part of a deposition layer that is formed to block light between the plurality of incident lenses and the plurality of emission lenses.

[0021] Among the plurality of shielding holes, the shielding holes continuously arranged in the left - right direction can communicate with each other to form an opening portion.

[0022] Each of the plurality of shielding holes can be formed in an overlapping region where corresponding incident lenses and outgoing lenses among the plurality of incident lenses and the plurality of outgoing lenses overlap.

[0023] The overlapping region can be a region where a region formed by an incident lens array that forms columns extending in the left - right direction among the plurality of incident lenses overlaps with a region formed by an outgoing lens array that forms columns extending in the left - right direction among the plurality of outgoing lenses.

[0024] When the optical portion inclinedly arranged in at least one direction is observed from the front - rear direction with the front - rear direction as a reference, the overlapping region can be a region where the incident lens array and the outgoing lens array overlap.

[0025] Each of the plurality of shielding holes can have its lower end portion located at the rear focal point of the corresponding outgoing lens among the plurality of outgoing lenses and its upper end portion located at the upper end side or the lower side thereof in the overlapping region.

[0026] Other specific matters of the present invention are included in the detailed description and the drawings.

[0027] According to the vehicle lamp of the present invention as described above, it has one or more of the following effects.

[0028] Since shielding holes are formed in the overlapping region where the plurality of incident lenses and the plurality of outgoing lenses overlap, light incident through the incident lenses beyond the overlapping region is prevented from passing through the outgoing lenses beyond the overlapping region, thereby preventing light from being irradiated in unnecessary directions and having the effect of being able to improve glare.

[0029] The effects of the present invention are not limited to the above - mentioned effects, and those skilled in the art can clearly understand other technical effects not mentioned through the description in the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Referring to the embodiments described in detail below in conjunction with the accompanying drawings, the advantages and features of the present invention and the methods for achieving these can be clarified. However, the present invention can be implemented in various different forms and is not limited to the embodiments disclosed below.

Therefore, depending on manufacturing techniques and / or allowable errors, etc., the shapes of the example diagrams may be deformed. Therefore, the embodiments of the present invention are not limited to the specific shapes shown, and variations in shapes generated according to manufacturing processes are also included. Also, in each of the drawings illustrated in the present invention, for the convenience of explanation, each component may be illustrated with some magnification or reduction. Throughout the specification, the same reference numerals refer to the same components.

[0049] Hereinafter, based on the embodiments of the present invention, the present invention will be described by referring to the drawings for illustrating vehicle lamps.

[0050] Figure 1 and Figure 2 is a perspective view showing a vehicle lamp according to an embodiment of the present invention, Figure 3 is a front view showing a vehicle lamp according to an embodiment of the present invention, Figure 4 is a side view showing a vehicle lamp according to an embodiment of the present invention, Figure 5 is a plan view showing a vehicle lamp according to an embodiment of the present invention.

[0051] Referring to Figures 1 to 5, taking the case where the vehicle lamp 1 according to an embodiment of the present invention includes a plurality of lamp modules 10 arranged in at least one direction as an example, where the X-axis represents the vehicle width direction as the left-right direction, the Y-axis represents the traveling direction as the front-back direction, and the Z-axis represents the vehicle height direction as the up-down direction for illustration, but is not limited thereto. The actual directions represented by the X-axis, Y-axis, and Z-axis may vary depending on the position or direction of the vehicle lamp provided according to the present invention.

[0052] In an embodiment of the present invention, taking the case where the vehicle lamp 1 is used as a headlamp to ensure the front view of the vehicle by irradiating light in the traveling direction of the vehicle when the vehicle travels at night or in a dark place such as a tunnel as an example for illustration, but is not limited thereto. The vehicle lamp 1 of the present invention can not only be used as a headlamp, but also be used as various lamps such as taillights, outline lamps, brake lamps, daytime running lamps, turn signal lamps, fog lamps, reverse lamps, etc. provided in the vehicle.

[0053] When the vehicle lamp 1 of the present invention is used as a headlamp, at least one of a low beam pattern and a high beam pattern can be formed. Among them, the low beam pattern irradiates light to the lower side based on a cut-off line of a predetermined shape and ensures a relatively wide field of view in front of the vehicle to prevent glare to the drivers of the front vehicles such as the preceding vehicle or the oncoming vehicle. The high beam pattern ensures a longer field of view distance in the long distance in front of the vehicle by irradiating at least a part of the light above the cut-off line. Hereinafter, in an embodiment of the present invention, as Figure 6 shown, taking the case of forming a low beam pattern P having a predetermined cut-off line CL as an example for illustration. In addition, in an embodiment of the present invention, taking the case where the vehicle lamp 1 includes a plurality of lamp modules 10 arranged in the up-down direction as an example for illustration, but this is only an example for helping to understand the present invention and is not limited thereto. According to the light distribution characteristics of the light beam pattern formed by the vehicle lamp 1 of the present invention (i.e., the position, size, shape, brightness, etc. of the light irradiation area), the number and arrangement direction of the lamp modules included in the vehicle lamp 1 according to the present invention can be variously changed.

[0054] At this time, taking the case where a plurality of lamp modules 10 are arranged in the up-down direction and the lamp modules are located in front from the upper side to the lower side and gradually located on the right side as an example for illustration, this is for arranging a plurality of lamp modules 10 along the body line of the vehicle.

[0055] In other words, the vehicle lamp 1 of the present invention can be accommodated in an internal space formed by a lamp housing (not shown) and a cover lens (not shown) coupled to the lamp housing, and a plurality of lamp modules 10 can be arranged according to the shape of the cover lens that forms a part of the body line of the vehicle.

[0056] For example, in the case where the cover lens has a planar shape facing the front of the vehicle from the front, the plurality of lamp modules 10 may be arranged in the vertical direction and may have the same positions in the front-rear direction and the left-right direction. In the case where the cover lens has a planar shape or a curved surface shape formed by being inclined at a predetermined angle in at least one direction with respect to the front of the vehicle, the plurality of lamp modules 10 may be arranged in the vertical direction, and adjacent lamp modules may be arranged to be offset from each other in at least one of the front-rear direction and the left-right direction.

[0057] The light beam pattern formed by the vehicle lamp 1 according to the present invention may be formed in such a manner that the light beam patterns formed by each of the plurality of lamp modules 10 overlap or are combined.

[0058] For example, the light beam pattern formed by the vehicle lamp 1 according to the present invention may be formed in such a manner that the light beam patterns having the same light distribution characteristics formed by each of the plurality of lamp modules 10 overlap each other, or may be formed in such a manner that the light beam patterns having different light distribution characteristics formed by each of the plurality of lamp modules 10 are combined.

[0059] Figure 7 and Figure 8 is a perspective view showing a lamp module according to an embodiment of the present invention, Figure 9 is a side view showing a lamp module according to an embodiment of the present invention, Figure 10 is a cross-sectional view showing an optical path conversion unit according to an embodiment of the present invention, Figures 7 to 10 is an example showing the case of any one of the plurality of lamp modules 10, and the remaining lamp modules may be similarly applied.

[0060] Referring to Figures 7 to 9 , the plurality of lamp modules 10 according to an embodiment of the present invention may include a light source unit 1000, an optical path conversion unit 2000, and an optical unit 3000.

[0061] The light source unit 1000 may include at least one light source that emits light having a light quantity or color suitable for the use of the vehicle lamp 1 according to the present invention. According to the use of the vehicle lamp 1 according to the present invention, at least one of the light quantity and color of the light emitted from the light source unit 1000 may be different.

[0062] In an embodiment of the present invention, a case where a semiconductor light-emitting element such as a light-emitting diode (LED) is used as at least one light source is taken as an example for illustration, but it is not limited thereto. The at least one light source can use not only LEDs, but also various types of light sources such as laser diodes (LDs) or bulbs, and components for controlling the brightness, path, color, etc. of light, such as reflectors, mirrors, prisms, phosphors, etc., can be additionally used according to the type of the light source.

[0063] The light source unit 1000 can be disposed such that the optical axis Ax is inclined at a predetermined angle θ in at least one direction with respect to the central axis C of the optical path conversion unit 2000. In an embodiment of the present invention, a case where the optical axis Ax of the light source unit 1000 is inclined upward with respect to the central axis C is taken as an example for illustration, so that the light source unit 1000 of each of the plurality of lamp modules 10 can be disposed on a common substrate 20.

[0064] For example, when the plurality of lamp modules 10 are arranged in the vertical direction and are gradually located on the right side while the lamp modules are located in the front from the upper side to the lower side, as described above Figure 4 and Figure 5 shown, it is necessary to incline the common substrate 20 in such a way that it is gradually located in the front from the upper side to the lower side, so that the light source unit 1000 of each of the plurality of lamp modules 10 can be disposed in a common substrate 20 along the arrangement direction of the plurality of lamp modules 10. Thus, it can be understood that the light source unit 1000 disposed on the common substrate 20 also inclines the optical axis Ax upward with respect to the central axis C.

[0065] In other words, the inclination direction of the common substrate 20 can be different according to the arrangement direction of the light source unit 1000 of each of the plurality of lamp modules 10, and the inclination direction of the optical axis Ax of the light source unit 1000 of each of the plurality of lamp modules 10 disposed on the common substrate 20 can also be different.

[0066] In this way, when the light source unit 1000 of each of the plurality of lamp modules 10 is disposed on a common substrate 20, compared with the case where a separate substrate is used for the light source unit 1000 of each of the plurality of lamp modules 10, the number of components can be reduced and the assembly process can be simplified, and an easier heat dissipation design can also be achieved.

[0067] At this time, the optical axis Ax of the light source unit 1000 can be understood as a line that vertically passes through the center of the light-emitting region formed by at least one light source.

[0068] For example, in the case where the light source unit 1000 includes a single light source, the axis vertically passing through the center of the light emitting surface of the single light source can be understood as the optical axis Ax. In the case where the light source unit 1000 includes a plurality of light sources, the axis vertically passing through the center of the light emitting region formed by the light emitting surfaces of the plurality of light sources can be understood as the optical axis Ax.

[0069] The optical path conversion unit 2000 can function to convert the optical path so that the light emitted from the light source unit 1000 travels along a set path. In an embodiment of the present invention, the optical path conversion unit 2000 can function to convert the light emitted from the light source unit 1000 into substantially parallel light and emit it.

[0070] The optical path conversion unit 2000 may include an incident portion 2100 and an emission portion 2200.

[0071] The incident portion 2100 may include a first incident surface 2110, a second incident surface 2120, and a reflection surface 2130. The end shape of the incident portion 2100 facing the light source unit 1000 may be inclined in a manner corresponding to the inclination direction of the optical axis Ax of the light source unit 1000.

[0072] That is, in an embodiment of the present invention, since the optical axis Ax of the light source unit 1000 is inclined upward with respect to the central axis C of the optical path conversion unit 2000, the end of the incident portion 2100 may be inclined so that the lower side is more forward than the upper side. The central axis C can be understood as an axis parallel to the front-rear direction and passing through the center of the incident portion 2100 and the center of the emission portion 2200.

[0073] The first incident surface 2110 may be formed to protrude toward the light source unit 1000 with the central axis C as the center. The second incident surface 2120 may be formed to protrude from the edge of the first incident surface 2110 in the direction toward the light source unit 1000. The reflection surface 2130 may be formed to extend forward from the protruding end of the second incident surface 2120, thereby functioning to reflect the light incident on the second incident surface 2120 in a manner that travels forward.

[0074] For example, the reflection surface 2130 is formed to have a curved surface shape that protrudes forward from the protruding end of the incident surface 2120 and the distance separated laterally gradually increases with the central axis C as the reference, so that the light incident on the second incident surface 2120 can be reflected in a manner that travels forward.

[0075] The emission portion 2200 may include a first emission surface 2210 and a second emission surface 2220.

[0076] In an embodiment of the present invention, the case where the first emission surface 2210 and the second emission surface 2220 are formed with different curvatures from each other is taken as an example for description. However, this is to refract the light incident on the incident portion 2100 at an appropriate refraction angle, so that the light incident on the incident portion 2100 is converted into substantially parallel light and emitted in a direction parallel to the central axis C of the optical path conversion portion 2000.

[0077] For example, the first emission surface 2210 may be formed in a shape convex forward, and the second emission surface 2220 may be formed in a substantially planar shape. In this case, the light emitted to the first emission surface 2210 can be refracted at a relatively larger refraction angle.

[0078] In an embodiment of the present invention, the first incident surface 2110 is formed to protrude rearward toward the light source portion 1000, and the first emission surface 2210 is formed to protrude forward. Among them, the case where the first emission surface 2210 is formed with a larger curvature than the first incident surface 2110 is taken as an example for description. However, this is only an example for helping to understand the present invention and is not limited thereto. The formation angles or curvatures of the first incident surface 2110, the second incident surface 2120, and the reflection surface 2130 for converting the light incident on the incident portion 2100 into substantially parallel light and emitting it, and the formation angles or curvatures of the first emission surface 2210 and the second emission surface 2220 can be changed in various ways.

[0079] Figure 11 is a front view showing an optical unit according to an embodiment of the present invention, Figure 12 is a rear view showing an optical unit according to an embodiment of the present invention, Figure 13 and Figure 14 is an exploded perspective view showing an optical unit according to an embodiment of the present invention.

[0080] Referring to Figures 11 to 14 , the optical unit 3000 according to an embodiment of the present invention may include a plurality of incident lenses 3100, a plurality of emission lenses 3200, a first light transmission portion 3300, and a second light transmission portion 3400.

[0081] The plurality of incident lenses 3100 may be arranged on the incident surface 3310 of the first light transmission portion 3300, the plurality of emission lenses 3200 may be arranged on the emission surface 3420 of the second light transmission portion 3400, and the emission surface 3320 of the first light transmission portion 3300 and the incident surface 3410 of the second light transmission portion 3400 may be adjacently provided facing each other or provided in contact with each other.

[0082] A plurality of incident lenses 3100 may be arranged such that an array A1 of incident lenses formed in columns extending in the left - right direction is arranged in the up - down direction. Similarly to the plurality of incident lenses 3100, a plurality of exit lenses 3200 may also be arranged such that an array A2 of exit lenses formed in columns extending in the left - right direction is arranged in the up - down direction.

[0083] A plurality of shielding holes 3500 may be formed in the incident surface 3410 of the second light - transmitting portion 3400. Each of the plurality of shielding holes 3500 may function to block a part of the light traveling to the corresponding exit lens among the plurality of exit lenses 3200 to form a cut - off line CL of a near - beam pattern P as Figure 6 shown.

[0084] The plurality of shielding holes 3500 may be formed by removing a part of a deposition layer 3411 formed on the incident surface 3410 of the second light - transmitting portion 3400 by an etching process, and the deposition layer 3411 may be formed of a material or color capable of blocking light.

[0085] The lower end portion of each of the plurality of shielding holes 3500 may be located at or near the rear focal point of the corresponding exit lens among the plurality of exit lenses 3200, so that, based on the rear focal point of the corresponding exit lens, the light traveling through the lower - side space can be blocked from being emitted.

[0086] That is, based on the rear focal point of each of the plurality of exit lenses 3200, the light traveling through the lower - side space is refracted and emitted in a direction relatively upward. Therefore, since it irradiates the upper side of the cut - off line CL and causes glare to the driver of the vehicle ahead, the lower end portion of each of the plurality of shielding holes 3500 is located at or near the rear focal point of the corresponding exit lens among the plurality of exit lenses 3200, thereby preventing the light traveling through the lower - side space based on the rear focal point of the corresponding exit lens from being emitted.

[0087] At this time, the rear focal point may have a shape of a point, a line, a plane, a space, or a combination thereof according to the region where the actual light is focused.

[0088] Among the plurality of shielding holes 3500, the shielding holes adjacent to each other in the left - right direction may communicate with each other to form one opening portion. Thus, compared with the case where the shielding holes adjacent to each other in the left - right direction are separated from each other by the deposition layer 3411, the diffusion characteristics can be improved by expanding the left - right width of the beam pattern formed by the vehicle lamp 1 of the present invention.

[0089] At this time, in Figure 14In [the figure], the dashed line formed between the shielding holes adjacent to each other in the left - right direction is used to indicate that the same emission lens array A2 is formed among the plurality of emission lenses 3200, and corresponds to each of the shielding holes of the emission lenses adjacent to each other in the left - right direction.

[0090] In an embodiment of the present invention, the optical part 3000 of each of the plurality of lamp modules 10 is arranged such that the lower side is more forward than the upper side in the up - down direction. Even when it is arranged such that the lower side is more to the right than the upper side in the left - right direction and the cover lens is formed to be inclined in at least one direction with respect to the front of the vehicle, the optical part 3000 can form an appearance identical to that of an overall optical part, so the overall sense is improved and an overall uniform lighting image is formed.

[0091] That is, when the optical part 3000 of each of the plurality of lamp modules 10 has a planar shape facing forward, there may be a case where the optical parts 3000 of each of the plurality of lamp modules 10 are arranged with a step difference in at least one direction between them according to the shape of the cover lens, resulting in a reduced overall sense and a likely non - uniform lighting image. In an embodiment of the present invention, since the optical part 3000 of each of the plurality of lamp modules 10 is formed to be inclined in at least one direction, even when the plurality of lamp modules 10 are arranged to be offset from each other according to the shape of the cover lens, the optical part 3000 of each of the plurality of lamp modules 10 can form an appearance identical to that of an overall optical part.

[0092] As described above, when the optical part 3000 is inclined in at least one direction, as Figure 15 shown, among the plurality of incident lenses 3100 and the plurality of emission lenses 3200, the corresponding incident lens 3100a and emission lens 3200a can be arranged to be offset from each other in at least one direction. Even in this case, since the light emitted from the optical part 3000 also needs to travel forward, the corresponding incident lens 3100a and emission lens 3200a can be formed such that, with a reference line R parallel to the front - rear direction as a reference, the two sides have different curvatures from each other.

[0093] At this time, Figure 15 is an example of the case where the optical part 3000 is inclined such that the lower side is more forward than the upper side in the up - down direction. In this case, it can be understood that the corresponding incident lens 3100a and emission lens 3200a are formed such that, with a reference line R parallel to the front - rear direction as a reference, the upper and lower parts have different curvatures from each other, and the reference line R can be understood as a line parallel to the front - rear direction and passing through the rear focal point F of the corresponding emission lens 3200a.

[0094] In addition, when observing the vehicle lamp 1 of the present invention from the front, a plurality of shielding holes 3500 may be formed in a region where the corresponding incident lenses and emission lenses among the plurality of incident lenses 3100 and the plurality of emission lenses 3200 overlap each other.

[0095] That is, in an embodiment of the present invention, the optical unit 3000 is inclined such that the lower side is more forward than the upper side in the vertical direction and the right side is more forward than the left side in the left - right direction. Thus, when observing the vehicle lamp 1 of the present invention from the front, among the plurality of incident lenses 3100 and the plurality of emission lenses 3200, at least a part of the corresponding incident lenses and emission lenses do not overlap with each other, and the shielding holes 3500 are not formed in the region where the corresponding incident lenses and emission lenses do not overlap, so that light whose path is difficult to control is not emitted, thereby preventing light from irradiating in an unnecessary direction.

[0096] Figure 16 is a schematic diagram showing an overlapping region between a plurality of incident lenses and a plurality of emission lenses according to an embodiment of the present invention, Figure 16 is an example showing a case of any one incident lens array and one emission lens array corresponding to each other in the incident lens array A1 formed by the plurality of incident lenses 3100 and the emission lens array A2 formed by the plurality of emission lenses 3200.

[0097] Refer to Figure 16 , when the optical unit 3000 is inclined such that one side is more forward than the other side in at least one direction, with the emission lens array A2 formed by the plurality of emission lenses 3200 as a reference, the incident lens arrays A1 formed by the plurality of incident lenses 3100 may be different from each other and may be arranged to be offset from each other in at least one direction. Thus, the overlapping region A0 where the corresponding incident lens array A1 and emission lens array A2 overlap is relatively smaller than the regions of the corresponding incident lens array A1 and emission lens array A2 respectively.

[0098] At this time, in the corresponding incident lens array A1 and emission lens array A2, since the light incident on at least a part of the incident lenses not located in the overlapping region A0 is difficult to control the light path, the light may not travel to the corresponding emission lens array A2 but travel to an adjacent other emission lens array, so that the light is irradiated in an unnecessary direction. Similarly, since the light emitted through at least a part of the emission lenses not located in the overlapping region A0 is also difficult to control the light path, it is irradiated in an unnecessary direction, which may cause glare.

[0099] Therefore, in an embodiment of the present invention, as Figure 17As shown, a plurality of shielding holes 3500 are formed in an overlapping region A0 where the incident lens array A1 and the exit lens array A2 corresponding to each other overlap. In a region beyond the overlapping region A0, the plurality of shielding holes 3500 are not formed, so that light incident on at least a part of the incident lenses not located in the overlapping region A0 is blocked by the deposition layer 3411. Similarly, light traveling toward at least a part of the exit lenses not located in the overlapping region A0 is blocked by the deposition layer 3411, thereby preventing glare caused by light irradiated in an unnecessary direction.

[0100] At this time, Figure 17 is an example when observing the vehicle lamp 1 of the present invention from the front. When observing the vehicle lamp 1 of the present invention from the front, in the case where the incident lens array A1 is further moved to the left in the left - right direction and further moved upward in the up - down direction compared with the exit lens array A2, the vicinity of the left end of the incident lens array A1, the vicinity of the right end of the exit lens array A2, and the vicinity of the upper end of the incident lens array A1 can be removed from the overlapping region A0. The lower end of the plurality of shielding holes 3500 is located at or near the rear focal point of the exit lenses forming the exit lens array A2 within the overlapping region A0, and according to the light distribution characteristics of the light beam pattern formed by the vehicle lamp 1 of the present invention, the upper end of the plurality of shielding holes 3500 is located at or below the upper end of the overlapping region A0 to block light irradiated in an unnecessary direction in advance.

[0101] In an embodiment of the present invention, the incident lenses forming columns in the left - right direction are not separated and are continuously formed. Similarly, since the exit lenses forming columns in the left - right direction are not separated and are continuously formed, the region where the incident lens array A1 and the exit lens array A2 corresponding to each other overlap is taken as an example for description. However, this is only an example for helping to understand the present invention and is not limited thereto. It can be understood that in the case where the incident lenses or the exit lenses adjacent to each other in the columns formed in the left - right direction are separated, as described above, the shielding holes 3500 are not formed in the region where the corresponding incident lenses and exit lenses do not overlap.

[0102] As described above, the vehicle lamp 1 according to the present invention is arranged such that the optical unit 3000 is inclined in at least one direction, so that the shielding holes 3500 are only formed in the overlapping region A0 where the plurality of incident lenses 3100 and the plurality of exit lenses 3200 overlap. Therefore, light incident on the incident lenses formed beyond the overlapping region A0 is blocked from exiting through the exit lenses formed beyond the overlapping region A0, thereby blocking light irradiated in an unnecessary direction, and thus preventing the generation of glare and the like.

[0103] Those with ordinary knowledge in the technical field to which the present invention pertains should presumably understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. Therefore, the above-described embodiments are exemplary in all aspects and should be understood as non-limiting embodiments. The scope of the present invention is not defined by the foregoing detailed description, but by the claims, and all variations or modifications that can be derived from the meaning, scope, and equivalent concepts of the claims should be construed as being included within the scope of the present invention.
