[0014] In order to achieve the above technical problems, the vehicle lamp according to the embodiment of the present utility model may include: a plurality of light sources, arranged in the up and down directions; and a plurality of light-guiding lenses, located in front of the plurality of light sources and formed integrally along the arrangement direction of the plurality of light sources, wherein the plurality of light-guiding lenses include: a first light-guiding lens; and a second light-guiding lens, arranged adjacent to the lower side of the first light-guiding lens, wherein a shielding hole is formed between the first light-guiding lens and the second light-guiding lens for inserting and setting a shielding object.

[0015] The shielding hole may include a shielding portion having a rear focus of an exit portion of light exiting from the first light guide lens as a vertex; and a connecting portion connecting both ends of the shielding portion in a front-rear direction.

[0016] The shielding portion may block a portion of light incident on the incident portion of the first light guide lens from traveling to the emitting portion of the first light guide lens.

[0017] The shielding portion may include: a shielding reflection portion formed so that the rear end is inclined downwardly toward the rear from the front end located at the rear side focus of the emission portion of the first light guide lens; a light extraction portion formed so as to be inclined downwardly toward the rear from the rear end of the shielding reflection portion; and a diffusion portion formed in front of the shielding reflection portion so as to be inclined downwardly toward the front.

[0018] The shielding reflection portion may reflect light reaching a predetermined area rearward with respect to a rear focal point of the emission portion of the first light guide lens so as to travel toward the first emission portion.

[0019] The light extraction portion may allow a portion of light incident on the incident portion of the first light guide lens to travel along a path set by at least one of transmission and reflection.

[0020] The light transmitted through the light extraction portion may be blocked from traveling to the emission portion of the first light guide lens by the shielding object inserted and disposed in the shielding hole.

[0021] The shield may be formed with a blocking wall at an upper portion to block light transmitting through the light extraction portion.

[0022] The light reflected by the light extraction portion travels obliquely upward toward the front, and at least a portion of the light reflected by the light extraction portion travels through a surface of a shielding hole formed between the first light guide lens and the light guide lens disposed adjacent to the upper side of the first light guide lens so as to be blocked by a shielding object inserted into the shielding hole formed between the first light guide lens and the light guide lens disposed adjacent to the upper side of the first light guide lens.

[0023] The connecting portion may include: a plurality of prism patterns formed in a front-to-rear direction in a manner forming a portion of an upper surface of the second light guide lens, wherein the shield is formed to have a plurality of diffusion patterns arranged in the front-to-rear direction on a lower surface thereof for diffusing light passing through at least one of the plurality of prism patterns.

[0024] Each of the plurality of diffusion patterns may be formed to extend in the left-right direction.

[0025] The plurality of diffusion patterns may include: a first diffusion pattern; and a second diffusion pattern disposed adjacent to a rear of the first diffusion pattern, wherein a rear surface of the first diffusion pattern is formed to gradually slope downward toward the front from an upper end to a lower end.

[0026] The front surface of the second diffusion pattern may be vertically formed.

[0027] Light transmitting at least one of the plurality of prism patterns may be reflected by a rear surface of the first diffusion pattern toward a front surface of the second diffusion pattern, and may be reflected at least twice.

[0028] A front surface and a rear surface of each of the plurality of diffusion patterns may be formed to have a larger inclination angle in an up-down direction than surfaces transmitting light from the plurality of prism patterns.

[0029] The plurality of diffusion patterns may be formed to have a higher formation density than the plurality of prism patterns.

[0037] When light emitted from multiple light sources is emitted through multiple light guide lenses formed integrally, the following effect is achieved: the shielding holes formed between adjacent light guide lenses in the multiple light guide lenses and the shielding objects inserted into the shielding holes can form the light cutoff line of the light beam pattern while preventing light from irradiating unnecessary areas.

[0038] Furthermore, since a common focus can be formed based on the inclination direction of the center line of the emission portion of the multiple light-guiding lenses and the inclination direction of the curvature of the incident surface of the multiple optical lenses in the up-down direction, it has the following effect: even if the light emitted from each of the multiple light-guiding lenses is incident not only on the corresponding optical lens among the multiple optical lenses, but also on another adjacent optical lens, it is possible to prevent the light from irradiating unnecessary areas.

[0039] Furthermore, the exit surfaces of the plurality of light-guiding lenses and the incident surfaces of the plurality of optical lenses have a common focus, and the exit surface of each of the plurality of optical lenses has a separate focus, so that the light incident on the incident surface of one of the plurality of optical lenses can utilize not only the light emitted through the exit surface of the corresponding optical lens, but also the light emitted through the exit surface of another adjacent optical lens. This has the effect of simultaneously forming a plurality of light beam patterns that are different from each other even without adding a separate optical system.

[0040] The effects of the present invention are not limited to the effects mentioned above, and those skilled in the art can clearly understand other technical effects that have not been mentioned through the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] Hereinafter, the present invention will be described based on embodiments of the present invention with reference to the accompanying drawings for describing a vehicle lamp.

[0076] Figure 1 and Figure 2 is a perspective view showing a vehicle lamp according to an embodiment of the present utility model, Figure 3 1 is a front view showing a vehicle lamp according to an embodiment of the present utility model. Figure 4 1 is a rear view showing a vehicle lamp according to an embodiment of the present invention. Figure 5 and Figure 6 1 is an exploded perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 7 yes Figure 3 A-A' line cross-section diagram. Among them, Figure 7 This is an example in which the mounting bracket 4000 is omitted.

[0077] Reference Figures 1 to 7 According to an embodiment of the present invention, the vehicle lamp 1 may include a plurality of light sources 1000 , a plurality of light guide lenses 2000 , and a plurality of optical lenses 3000 , and at least one of the components 1000 , 2000 , 3000 may be configured to be accommodated in a space formed by the mounting bracket 4000 .

[0078] In an embodiment of the present invention, the vehicle lamp 1 is explained using the following situation as an example: when a vehicle is driving at night, the headlight is used to irradiate light in the direction of travel of the vehicle to ensure the front field of vision of the vehicle, and the following situation is used as an example for explanation: the X-axis direction is the left and right direction, indicating the width direction of the vehicle, the Y-axis direction is the front and back direction, indicating the driving direction, and the Z-axis is the up and down direction, indicating the height direction of the vehicle, but it is not limited to this. According to the position or direction of the vehicle lamp 1 of the present invention, the directions actually represented by the X-axis, Y-axis and Z-axis can be changed.

[0079] In the embodiment of the present invention, the situation where the vehicle lamp 1 is used as a headlamp is only an example to help understand the present invention and is not limited to this. In addition to being used as a headlamp, the vehicle lamp 1 of the present invention can also be used as various lamps arranged in the vehicle, such as taillights, brake lights, turn signal lights, daytime running lights, backup lights and fog lights.

[0080] 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. In order to prevent dazzle to the driver of a vehicle in front, such as a preceding vehicle or an oncoming vehicle, the low beam pattern irradiates light downward based on the light-dark cutoff line to ensure a wide field of view at a short distance in front of the vehicle. The high beam pattern ensures a long field of view at a long distance in front of the vehicle. In the following, in the embodiments of the present invention, the following cases will be used as examples for explanation: Figure 8 As shown, a low beam pattern P that irradiates light downward is formed with the cut-off line CL as a reference.

[0081] The plurality of light sources 1000 can generate light having a light quantity or color suitable for the application of the vehicle lamp 1 of the present invention.

[0082] In an embodiment of the present invention, a case where multiple light sources 1000 are arranged in the up-down direction and further moved toward one side along the left-right direction from the upper side to the lower side will be described as an example, so that the multiple light sources 1000 are formed along the main body line of the vehicle.

[0083] For example, the vehicle lamp 1 of the present invention can be configured to be housed in an internal space formed by a lamp housing (not shown) and a cover lens (not shown) assembled to the lamp housing, and it can be understood that it is intended to arrange multiple light sources 1000 according to the shape of the cover lens that forms a part of the main body line of the vehicle.

[0084] In other words, in the case where the cover lens has a flat surface shape with the front side facing forward, the plurality of light sources 1000 are arranged in the up-down direction and have the same position in the left-right direction, but in the case where the cover lens has a flat surface or a curved surface shape formed obliquely relative to the front, the plurality of light sources 1000 can be arranged so as to move further toward one side in the left-right direction from one side to the other side in the up-down direction.

[0085] The situation where the plurality of light sources 1000 are arranged along the main body line of the vehicle can be understood as the situation where the plurality of light guide lenses 2000 and the plurality of optical lenses 3000 are similarly arranged along the main body line of the vehicle, which will be described in detail later.

[0086] At this time, as the plurality of light sources 1000 , the plurality of light guide lenses 2000 and the plurality of optical lenses 3000 are arranged along one direction, the vehicle lamp 1 of the present invention can achieve a slim appearance design along one direction, thereby improving the aesthetic sense.

[0087] In the embodiments of the present invention, the case where semiconductor light-emitting elements such as light-emitting diodes (LEDs) are used as multiple light sources 1000 is described as an example, but it is not limited to this. The multiple light sources 1000 can use not only LEDs, but also various types of light sources such as laser diodes (LDs) or light bulbs. In addition, optical elements such as reflectors, prisms, mirrors, phosphors, etc. for adjusting the path, brightness, color, etc. of light can be used according to the type of light source.

[0088] Figure 9 1 is a front view showing a plurality of light guide lenses according to an embodiment of the present utility model. Figure 10 1 is a rear view showing a plurality of light guide lenses according to an embodiment of the present invention, Figure 11 is a side view showing a plurality of light guide lenses according to an embodiment of the present utility model, Figure 12 yes Figure 9 The BB' line cross section, Figure 13 yes Figure 11 The C-C' line cross-section diagram, Figure 14 1 is a rear view showing a first light guide lens and a second light guide lens according to an embodiment of the present invention.

[0089] Reference Figures 9 to 14 According to an embodiment of the present invention, each of the plurality of light guide lenses 2000 may be located in front of the plurality of light sources 1000 so that light incident from a corresponding light source among the plurality of light sources 1000 is emitted.

[0090] The plurality of light guide lenses 2000 may be integrally formed in the up-down direction along the arrangement direction of the plurality of light sources 1000 , and may be arranged to move further toward one side in the left-right direction from one side to the other due to similar reasons as the plurality of light sources 1000 .

[0091] Each of the multiple light-guiding lenses 2000 may include: an incident portion 2010, for incident light emitted from a corresponding light source among the multiple light sources 1000; an emitting portion 2020, located in front of the incident portion 2010, for emitting the light incident on the incident portion 2010; and a transmitting portion 2030, for transmitting at least a portion of the light incident on the incident portion 2010 to the emitting portion 2020.

[0092] The incident portion 2010 of each of the plurality of light guide lenses 2000 may be disposed to be spaced apart at a predetermined interval to prevent interference between lights emitted from corresponding ones of the plurality of light sources 1000 .

[0093] In each of the plurality of light guide lenses 2000 , the incident portion 2010 and the emission portion 2020 may be connected via the transfer portion 2030 to be integrally formed with each other, and thus the number of components may be reduced and the assembly process may be simplified.

[0094] Also, the emission portion 2020 of each of the plurality of light guide lenses 2000 may have a curved surface shape convex toward the front to collect the emitted light.

[0095] At this time, the incident portion 2010 of each of the multiple light-guiding lenses 2000 can be arranged at a predetermined distance from the corresponding light source in the multiple light sources 1000 in the front-to-back direction. This is to prevent structural interference between the multiple light sources 1000 and the corresponding light sources in the multiple light-guiding lenses 2000 and the light-guiding lenses, and to improve the heat dissipation effect.

[0096] That is, when each of the multiple light sources 1000 is configured to be at least partially in contact with the incident portion 2010 of the corresponding light guide lens among the multiple light guide lenses 2000 along the front-to-back direction, the high-temperature heat generated when light is emitted from each of the multiple light sources 1000 cannot be quickly released to the outside due to the incident portion 2010, thereby resulting in a decrease in the heat dissipation effect. Therefore, the incident portion 2010 of each of the multiple light guide lenses 2000 can be set to be separated from the corresponding light source among the multiple light sources 1000 by a predetermined distance along the front-to-back direction.

[0097] The multiple light-guiding lenses 2000 can be formed so that the closer the light-guiding lens is to the lower side, the longer its length along the front-to-back direction is. This is because the multiple light sources 1000 are at the same position in the front-to-back direction. On the contrary, the closer the multiple optical lenses 3000 are to the lower side from the upper side, the closer they are to the front.

[0098] That is, when multiple optical lenses 3000 are located in the front from the upper side to the lower side along the main line of the vehicle, the light-guiding lenses located on the lower side of the multiple light-guiding lenses 2000 need to form a step difference so that the emission portion 2020 is located in the front. When multiple light sources 1000 have the same position in the front-to-back direction so that they can be arranged on a common substrate, the light-guiding lenses located on the lower side of the multiple light-guiding lenses 2000 have a longer length along the front-to-back direction, so that the light-guiding lenses located on the lower side of the multiple light-guiding lenses 2000 have a longer length in the front-to-back direction, so that the emission portion 2020 is located in the front.

[0099] In this case, the plurality of light sources 1000 are provided on a common substrate because, compared with a case where a separate substrate is used for each of the plurality of light sources 1000 , the number of components is reduced, thereby reducing costs and simplifying the assembly process.

[0100] The multiple light-guiding lenses 2000 may include a first light-guiding lens 2100 and a second light-guiding lens 2200 located below the first light-guiding lens 2100. In the following, in an embodiment of the present invention, the following situation will be used as an example for explanation: the first light-guiding lens 2100 and the second light-guiding lens 2200 are a general term for two light-guiding lenses in the multiple light-guiding lenses 2000 that are arranged adjacent to each other in the up and down directions and formed into one body.

[0101] The first light guide lens 2100 may include a first incident portion 2110 , a first emitting portion 2120 , and a first transmitting portion 2130 .

[0102] The first incident portion 2110 may function to focus light incident from a corresponding first light source 1100 among the plurality of light sources 1000 on or near a rear focus F1 of the first emitting portion 2120 .

[0103] At this time, the rear focus F1 of the first emission portion 2120 can have the shape of a point, line, surface, space or a combination thereof according to the actual focusing area. Below, in the embodiments of the present invention, the case where the focus has the shape of a point, line, surface, space or a combination thereof similar to the rear focus F1 of the first emission portion 2120 will be used as an example for explanation.

[0104] The first incident portion 2110 may include: a first central plane 2111, centered on the optical axis Ax1 of the first light source 1100 corresponding to the first light guide lens 2100 among the multiple light sources 1000; a first protruding surface 2112, formed to protrude from the edge of the first central plane 2111 toward the first light source 1100; and a first reflecting surface 2113, reflecting the light incident on the first protruding surface 2112 so that it moves toward the first emission portion 2120, wherein the first reflecting surface 2113 can be formed so that the distance separated from the optical axis Ax1 along the side gradually increases from the rear end to the front end along the direction of the optical axis Ax1 of the first light source 1100, so that the light incident on the first protruding surface 2112 moves forward.

[0105] At this time, at least a portion of the first reflective surface 2113 may be formed with a first corrosion portion 2113a. The first corrosion portion 2113a can prevent at least a portion of unnecessary light in the light incident on the first protruding surface 2112 from being reflected by the first reflective surface 2113, and transmit the light to the outside of the first light-guiding lens 2100 and travel therethrough, thereby pre-removing unnecessary light that may cause glare, etc.

[0106] In an embodiment of the present invention, the first corrosion portion 2113a can be formed in at least one of the upper and lower portions with the optical axis Ax1 of the first light source 1100 as a reference, and the area where the first corrosion portion 2113a is formed in at least one of the upper and lower portions of the first reflective surface 2113 can be variously changed.

[0107] The first transmission portion 2130 may transmit at least a portion of the light incident on the first incident portion 2110 to the first emission portion 2120 .

[0108] At this time, since the first incident part 2110 and the first emission part 2120 can be connected by the first transmission part 2130 and formed integrally with each other, the number of parts can be reduced and the assembly process can be simplified compared to the case where the first incident part 2110 and the first emission part 2120 are formed and assembled separately.

[0109] Similar to the first light guide lens 2100 , the second light guide lens 2200 may include a second incident portion 2210 , a second emitting portion 2220 , and a second transmitting portion 2230 .

[0110] The second incident portion 2210 may include: a second central plane 2211, centered on the optical axis Ax2 of the second light source 1200 corresponding to the second light guide lens 2200 among the multiple light sources 1000; a second protruding surface 2212, protruding from the edge of the second central plane 2211 toward the second light source 1200; and a second reflecting surface 2213, reflecting the light incident on the second protruding surface 2212 so that it moves toward the second emitting portion 2220.

[0111] The second central plane 2211, the second protruding surface 2212 and the second reflecting surface 2213 are different from the above-mentioned first central plane 2111, the first protruding surface 2112 and the first reflecting surface 2113 in some shapes, but they can play similar roles, so the detailed description of their functions will be omitted.

[0112] Furthermore, similar to the above-mentioned first reflecting surface 2113, the second reflecting surface 2213 can be formed with a second corrosion portion 2213a, and the second corrosion portion 2213a can prevent at least a portion of unnecessary light in the light incident on the second protruding surface 2212 from being reflected by the first reflecting surface 2113, so that it is transmitted to the outside of the first light-guiding lens 2200 and travels, thereby playing the role of pre-removing unnecessary light that may cause glare, etc.

[0113] At this time, the second corrosion portion 2213a may have the same formation position and formation area as the first corrosion portion 2113a, or at least one of the formation position and formation area may be different from each other. Figure 14 This is an example of a case where the first corrosion portion 2113 a and the second corrosion portion 2213 a are formed at different positions and in different areas.

[0114] Similar to the first incident portion 2110 , the second incident portion 2210 may focus light incident from a corresponding second light source 1200 among the plurality of light sources 1000 on or near the rear focus F2 of the second emission portion 2220 .

[0115] In addition, in order to form the vehicle lamp 1 according to the present invention Figure 8 In order to form a low-beam beam pattern P, it is necessary to block a portion of the light incident from each of the multiple light guide lenses 2000 to form a bright-dark cut-off line CL. As described above, when the first light guide lens 2100 and the second light guide lens 2200 are formed integrally, in order to block a portion of the light incident to the first light guide lens 2100, a shielding hole 2300 for blocking light can be formed between the first light guide lens 2100 and the second light guide lens 2200.

[0116] In the embodiment of the present invention, the shielding hole 2300 formed between the first light guide lens 2100 and the second light guide lens 2200 among the multiple light guide lenses 2000 will be used as an example for description, but the present invention is not limited to this. The shielding hole can also be formed between the first light guide lens 2100 and the light guide lens adjacent to the upper side of the first light guide lens 2100. Similarly, it can be understood that the shielding hole can also be formed between the second light guide lens 2200 and the light guide lens adjacent to the lower side of the second light guide lens 2200.

[0117] The shielding holes 2300 may be formed such that the size of the holes gradually increases along a direction in which a mold is separated during injection molding of the plurality of light guide lenses 2000 , thereby preventing undercutting during injection molding of the plurality of light guide lenses 2000 .

[0118] The shielding hole 2300 may include a shielding portion 2310 and a connecting portion 2320 .

[0119] The shielding portion 2310 can be formed to be approximately inclined downward along the front-to-back direction with the vertex located at the rear focus F1 of the first emission portion 2220 or its vicinity as a reference, and the connecting portion 2320 can be formed to connect the two ends of the shielding portion 2310 along the front-to-back direction, so that the shielding hole 2300 as a whole has a roughly triangular shape, and the light-guiding lens located at the lowest end of the multiple light-guiding lenses 2000 can be formed to have a concave shape by the shielding portion 2310 by omitting the connecting portion 2320 from the shielding hole 2300.

[0120] The shielding portion 2310 may include a shielding reflection portion 2311 , a light extraction portion 2312 , and a diffusion portion 2313 .

[0121] The shielding reflection portion 2311 can be formed to be inclined downward toward the rear from the front end located at the rear focus F1 of the first emission portion 2120 or its vicinity, and the front end of the shielding reflection portion 2311 represents the vertex of the above-mentioned shielding portion 2310, and can be located at a position closest to the optical axis Ax1 of the first light source 1100.

[0122] The front end of the shielding reflection portion 2311 is located at or near the rear focus F1 of the first emitting portion 2120 in order to form a cut-off line CL of the low beam pattern P. In the embodiment of the present invention, the following situation is used as an example for explanation: Figure 13 As shown, the front end of the shielding reflection portion 2311 is formed with a step difference so that the heights of both sides are different from each other with respect to the center portion in the left-right direction.

[0123] At this time, the shielding reflection portion 2311 is formed to have a step difference in the left and right directions in order to Figure 8 As shown, the cut-off line CL of the low beam pattern P formed by the vehicle lamp 1 of the present invention has different heights on both sides based on the center part, but is not limited to this. According to the shape of the cut-off line CL, the shielding reflection part 2311 can be formed to have the same height in the left and right directions, or different parts can be formed to have different heights.

[0124] In an embodiment of the present invention, the case where the size of the shielding hole 2300 is larger along the direction of mold separation is used as an example for explanation, but it is not limited to this. When the front end of the shielding reflection part 2311 is formed to have different heights on both sides based on the center part, it has a larger size in the direction from the side with a lower height toward the other side with a higher height, so that undercutting will not occur due to the step difference.

[0125] In addition, when the step difference of the shielding reflection portion 2311 at the rear focus F1 of the first emission portion 2120 is removed, a portion of the light passing through the rear focus F1 may be blocked. Therefore, an extension portion 2311a that is inclined downward from the front end of the shielding reflection portion 2311 may be formed in front of the shielding reflection portion 2311, and the extension portion 2311a may play a role as follows: Figure 15 This has the effect of extending the step of the shielding reflection portion 2311 to a predetermined area in front of the shielding reflection portion 2311 .

[0126] The above-mentioned shielding reflection portion 2311 can be formed to be inclined downward toward the rear with the front end as the reference, so that a portion of the light that is incident on the first incident portion 2110 and converges at the rear focus F1 of the first emission portion 2120 and travels is reflected toward the first emission portion 2120. This is to prevent the light used to form a beam pattern suitable for the purpose of the vehicle lamp 1 of the present invention from being blocked and reducing the light efficiency.

[0127] That is, the first light source 1100 may be a surface light source having a light emitting surface of a predetermined size, and it can be understood that the propagation surface of the light emitted from the first light source 1100 may also have a size corresponding to the light emitting surface.

[0128] At this time, since the light focused on the rear focus F1 of the first emitting portion 2120 also has a propagation surface of a size corresponding to the light emitting surface of the first light source 1100, the area of ​​the propagation surface located behind the rear focus F1 of the first emitting portion 2120 can be blocked by the front end of the shielding reflector 2311. Figure 16 As shown, among the light L11 and L12 that are incident on the first incident portion 2110 and converged in the first emitting portion 2120 and travel therethrough, the light L12 that reaches a predetermined rear area based on the shielding reflection portion 2311 is reflected in a manner that travels toward the first emitting portion 2120, thereby improving light efficiency.

[0129] In other words, when the center of the propagation surface of the light emitted from the first light source 1100 is located at the rear focus F1 of the first emission portion 2120, the front area in the propagation surface is used as a reference, and can move to the first emission portion 2120 without being blocked. On the contrary, with the rear focus F1 in the propagation surface as a reference, the area located at the rear is blocked, and light loss may occur. Therefore, it is reflected by the shielded reflection portion 2311 and can move toward the first emission portion 2120. Therefore, the light efficiency of the light beam pattern formed by the vehicle lamp 1 of the present invention can be improved.

[0130] The light extraction portion 2312 may be located behind the shielding reflection portion 2311 , and thus may play a role in extracting unnecessary light from the light incident on the first incident portion 2110 so as to travel along a predetermined path.

[0131] In an embodiment of the present invention, unnecessary light in the light incident on the first incident portion 2110 can be understood as light that is irradiated into the area irradiated by the light emitted through the first emission portion 2120 and is out of the position of the beam pattern suitable for the purpose of the vehicle lamp 1 of the present invention, thereby causing glare, etc.

[0132] The light extraction portion 2312 can extract unnecessary light from the light incident on the first incident portion 2110 before it is emitted to the first emission portion 2120. In the embodiment of the present invention, the following situation is used as an example for explanation: Figure 17 As shown, the light extraction portion 2312 allows the light L21 and L22 that causes glare, etc. in the light incident on the first incident portion 2110 to be transmitted and travel or reflected and travel obliquely upward toward the front, but is not limited to this. The light extraction portion 2312 can allow the light that causes glare, etc. to travel along a set path by at least one of transmission and reflection.

[0133] For example, Figure 18 As shown, unnecessary light in the light incident on the first incident portion 2110 can not only form a low beam pattern P suitable for the purpose of the vehicle lamp 1 of the present invention, but also illuminate an unnecessary area P', which may cause dazzle to the driver of the vehicle in front or reduce the driver's forward field of vision. Therefore, the light extracted by the light extraction portion 2312 travels along the set path, thereby preventing the unnecessary area P' from being illuminated in advance.

[0134] In an embodiment of the present invention, the case where the light extraction portion 2312 is tilted downward from the front end connected to the rear end of the shielding reflection portion 2311 will be used as an example for explanation, but it is not limited to this. Depending on the path of the light extracted by the light extraction portion 2312, the formation angle or size of the light extraction portion 2412 can be changed in various ways.

[0135] In addition, although the case where the rear end of the light extraction portion 2312 is connected to the connecting surface 2312a via the rear end of the connecting portion 2320 and the light extraction portion 2312 and the connecting surface 2312a have different angles from each other is described as an example, this is because when the light extraction portion 2312 is extended as it is, structural interference occurs with the first incident portion 2110, making it difficult to form multiple light-guiding lenses 2000 in one piece.

[0136] The diffusion portion 2313 can be formed to be inclined downward from the front end of the extension portion 2311a toward the front, and the diffusion portion 2313 is separated from the front end of the shielding reflection portion 2311 because the extension portion 2311a is formed at the front end of the shielding reflection portion 2311 as described above. When the shielding reflection portion 2311 does not form a step difference, the diffusion portion 2313 can be formed to be connected to the front end of the shielding reflection portion 2311.

[0137] like Figure 19 As shown, the diffusion portion 2313 may include: at least one diffusion pattern 2313a, for diffusing the light L22 reflected by the light extraction portion 2312 and traveling toward the front, which is not transmitted through the connecting portion of the shielding hole formed between the first light guide lens 2100 and the light guide lens arranged adjacent to the upper side of the first light guide lens 2100 and is reflected.

[0138] That is, a part of the light L22a in the light L22 reflected by the light extraction portion 2312 and traveling forward will be transmitted through the connecting portion of the shielding hole formed between the first light guide lens 2100 and the light guide lens arranged adjacent to the upper side of the first light guide lens 2100, while the other part of the light L22b cannot be transmitted through the connecting portion and is reflected. In this case, the light L22b that cannot be transmitted through the connecting portion and is reflected is diffused by the diffusion portion 2313, thereby preventing glare, etc.

[0139] At this time, the front end of the diffusion part 2313 and the front end of the connecting part 2320 can be connected by a curved surface 2313b with a predetermined curvature. The curved surface 2313b plays a role in diffusing the following light to prevent the light from moving forward and generating glare: the light is the light that is reflected by the light extraction part of the shielding hole formed between the second light-guiding lens 2200 and the light-guiding lens adjacent to the lower side of the second light-guiding lens 2200 and passes through the connecting part 2320, and the light whose energy is not sufficiently reduced by the shielding object 4110 described later. A detailed description of this will be described later.

[0140] The connecting portion 2320 may form a portion of the upper surface of the second light guide lens 2200 and may be formed with a plurality of prism patterns 2321 for guiding the path of unnecessary light in the light incident into the second incident portion 2210, and one of the plurality of prism patterns 2321 may be formed to have a size different from that of another prism pattern.

[0141] At this time, the purpose of forming one of the multiple prism patterns 2321 to have a size different from that of another prism pattern is to make the prism pattern formed at a position with relatively more light have a larger size, so that the light passing through the prism pattern travels along an appropriate path.

[0142] In other words, when multiple prism patterns with relatively small sizes are formed in the connecting portion 2320 at positions where a relatively large amount of light is transmitted, it is relatively difficult to control the paths of light that transmits each of the multiple prism patterns. Therefore, the size of the prism pattern can be increased to facilitate the control of the path of light, wherein the size of each of the multiple prism patterns 2321 can be the same as or different from each other depending on the amount of light that transmits the connecting portion 2320.

[0143] like Figure 20 As shown, preferably, when the spacing d between the upper surface and the lower surface of the second light guide lens 2200 is set to 100%, the plurality of prism patterns 2321 are formed in an area having a spacing d' of approximately 25% in the direction from the upper surface toward the lower surface. This is because, when the plurality of prism patterns 2321 are formed at a position having a spacing exceeding 25% of the spacing d' in the direction from the upper surface toward the lower surface of the second light guide lens 2200, there is a high possibility of interference with the light incident on the second incident portion 2210 and traveling to the second emission portion 2220. On the contrary, when the plurality of prism patterns 2321 are located on the upper side compared to the upper surface of the plurality of prism patterns 2321 (that is, when the first light guide lens 2100 is formed to be located on the upper side compared to the lower surface of the first light guide lens 2100), unnecessary light in the light incident on the first incident portion 2210 is transmitted through the connecting portion 2320, and the path of the light becomes longer, making it difficult to control the path of the light, which may become a cause of glare.

[0144] The plurality of optical lenses 3000 may play a role in transmitting light emitted from corresponding light guide lenses among the plurality of light guide lenses 2000 to form a beam pattern suitable for the application of the vehicle lamp 1 according to the present invention.

[0145] Figure 21 and Figure 22 is a perspective view showing a plurality of optical lenses according to an embodiment of the present invention.

[0146] Reference Figure 21 and Figure 22 , the multiple optical lenses 3000 can be formed integrally along the up and down direction similar to the multiple light guide lenses 2000, and can be formed inclined in such a manner that the multiple optical lenses 3000 are further moved toward one side along the left and right direction from the upper side toward the lower side.

[0147] In an embodiment of the present invention, an example will be given in which each of the multiple optical lenses 3000 is formed with one side located in front of the other side along the left-right direction, in order to be formed along the main body line of the vehicle similarly to the multiple light sources 1000 and the multiple light-guiding lenses 2000.

[0148] Each of the multiple optical lenses 3000 can cause the light incident on the incident surface 3010 to be emitted through the exit surface 3020, and each of the multiple optical lenses 3000 can be formed into a curved surface shape with the incident surface 3010 concave forward. This is to enable the exit portions 2020 of the light-guiding lenses corresponding to each other in the multiple light-guiding lenses 2000 and the multiple optical lenses 3000 and the incident surface 3010 of the optical lenses to have a common focus. A detailed description of this will be described later.

[0149] In an embodiment of the present invention, in order to easily control the optical path of light transmitting through multiple optical lenses 3000, the case where the emission surface 3020 includes multiple facets 3021 will be used as an example for explanation, but this is only an example to help understand the present invention and is not limited to this. Among the multiple optical lenses 3000, at least one of the incident surface 3010 and the emission surface 3020 can be composed of multiple facets.

[0150] In an embodiment of the present invention, the case where the incident surfaces of the optical lenses adjacent to each other in the multiple optical lenses 3000 are formed to have a step difference between each other is taken as an example for explanation, but it is not limited to this. The incident surfaces of the optical lenses adjacent to each other in the multiple optical lenses 3000 can be formed to be continuous without a step difference.

[0151] At this time, a common focus is formed by the emission portions 2020 of the light-guiding lenses corresponding to each other in the multiple light-guiding lenses 2000 and the incident surfaces 3010 of the optical lenses, because, when separate focal points different from each other are formed by the emission portions 2020 of the light-guiding lenses corresponding to each other in the multiple light-guiding lenses 2000 and the incident surfaces 3010 of the optical lenses, light emitted from each of the multiple light-guiding lenses 2000 is incident not only on the corresponding optical lens in the multiple optical lenses 3000, but also on other adjacent optical lenses, in which case glare, etc. may be generated.

[0152] In order to make the emission portions 2020 of the light guide lenses and the incident surfaces 3010 of the optical lenses corresponding to each other in the plurality of light guide lenses 2000 and the plurality of optical lenses 3000 have a common focus, as shown in FIG. Figure 23 As shown, the center line C of the emission portion 2020 of at least one of the plurality of light guide lenses 2000 can be formed to be inclined in a predetermined direction with respect to a first reference line R1 parallel to the front-rear direction and passing through the centers of the plurality of light guide lenses 2000 in the left-right direction.

[0153] That is, the light-guiding lenses located on both sides with respect to a first reference line R1 passing through the center of the plurality of light-guiding lenses 2000 in the left and right directions can be formed so that the center line C of the emission portion 2020 is inclined at a predetermined angle in the direction toward the first reference line R1, and the center line C of the emission portion 2020 of each of the plurality of light-guiding lenses 2000 can be understood as an axis that enables the emission portion 2020 to be formed into rotational symmetry.

[0154] For example, the optical axis Ax of the corresponding light source among the multiple light-guiding lenses 2000 is formed with the first reference line R1 as the reference, and the emission portion 2020 of the light-guiding lens located on the left side is formed with the center line C inclined toward the first reference line R1 and inclined toward the right side by a predetermined angle θ1. On the contrary, the optical axis Ax of the corresponding light source among the multiple light-guiding lenses 2000 is formed with the first reference line R1 as the reference, and the emission portion 2020 of the light-guiding lens located on the right side is formed with the center line C inclined toward the first reference line R1 and inclined toward the left side by a predetermined angle θ2.

[0155] At this time, multiple light-guiding lenses 2000 can be formed to be inclined at different angles from each other according to the distances separated in the left-right direction based on the first reference line R1. As an example, the more light-guiding lenses 2000 are separated by a greater distance from the first reference line R1 in the up-down direction, the emission portion 2020 can be formed to be inclined at a larger angle.

[0156] Furthermore, in order to make the emitting portions 2020 of the light guide lenses corresponding to each other and the incident surfaces 3010 of the optical lenses in the plurality of light guide lenses 2000 and the plurality of optical lenses 3000 have a common focus, as shown in FIG. Figure 24 As shown, with a second reference line R2 parallel to the front-to-back direction and passing through the centers of the multiple light-guiding lenses 2000 on the upper and lower sides as a reference, the incident surface 3010 of the optical lens located on the upper and lower sides can be formed with a curvature in the upper and lower directions with a reference to a vertical line of the optical axis Ax of the light source corresponding to each of the multiple light sources 1000 and passing vertically through the multiple light sources 1000, and tilted toward one of the two sides.

[0157] That is, the incident surface 3010 of the optical lens located on the upper side with respect to the second reference line R2 among the multiple optical lenses 3000 can be formed so that the curvature Rv in the up-down direction is inclined toward the right side with respect to the vertical line Lv. Conversely, the incident surface 3010 of the optical lens located on the lower side with respect to the second reference line R2 can be formed so that the curvature Rv in the up-down direction is inclined toward the left side with respect to the vertical line Lv.

[0158] At this time, the curvature Rv of the incident surface 3010 of the optical lens located on the upper side with the second reference line R2 as the reference is inclined toward the right side with the vertical line Lv as the reference, and the curvature Rv of the incident surface 3010 of the optical lens located on the lower side with the second reference line R2 as the reference is inclined toward the left side with the vertical line Lv as the reference. This is because, as Figure 23 As shown, the optical axis Ax of the corresponding light source in the optical lens located on the upper side with the second reference line R2 as the reference is located on the left side with the first reference line R1 as the reference, and the optical axis Ax of the corresponding light source in the optical lens located on the lower side with the second reference line R2 as the reference is located on the right side with the first reference line R1 as the reference.

[0159] As described above, the center line C of the emission portion 2020 of the multiple light-guiding lenses 2000 is tilted in the left-right direction with the first reference line R1 as the reference, and the curvature Rv in the upper and lower directions of the incident surface 3010 of each of the multiple optical lenses 3000 is tilted in the left-right direction with the vertical line Lv as the reference. This is because a common focus is formed by combining the emission portion 2020 of each of the multiple light-guiding lenses 2000 and the incident surface 3010 of the multiple optical lenses 3000 corresponding to each of the multiple light-guiding lenses 2000. Accordingly, even if the light emitted from each of the multiple light-guiding lenses 2000 is incident not only on the corresponding optical lens in the multiple optical lenses 3000 but also on another adjacent optical lens, it can travel in the form of parallel light, thereby preventing glare.

[0160] In addition, the vehicle lamp 1 according to the present invention may further include a mounting bracket 4000 including a shield 4110 inserted into and positioned in the shielding hole 2300 formed between the first light guide lens 2100 and the second light guide lens 2200 .

[0161] The mounting bracket 4000 may include a first bracket 4100 formed with a shield 4110 and a second bracket 4200 assembled with the first bracket 4100. When the first bracket 4100 is arranged so that the shield 4110 is inserted into the shielding hole 2300 from one side of the plurality of light guide lenses 2000, the second bracket 4200 is assembled to the first bracket 4100 on the other side of the plurality of light guide lenses 2000, thereby fixing their relative positions.

[0162] In an embodiment of the present invention, the following situation will be taken as an example for description: at least one assembly protrusion 4100a is formed on the first bracket 4100, and at least one assembly groove 4200a is formed on the second bracket 4200, so that they are assembled with each other, but it is not limited to this. The first bracket 4100 and the second bracket 4200 can be assembled by various methods such as threaded connection, hook connection, adhesive, etc.

[0163] When assembling the first bracket 4100 and the second bracket 4200, the mounting bracket 4000 can be formed with an opening portion 4300 corresponding to the multiple optical lenses 3000, thereby preventing light leakage from the multiple light sources 1000 during the process of transmitting through the multiple optical lenses 3000 after passing through the multiple light guide lenses 2000.

[0164] In an embodiment of the present invention, the case where the frame 4310 for forming the opening portion 4300 is formed integrally with the second bracket 4200 will be used as an example for explanation, but it is not limited to this. The frame 4310 for forming the opening portion 4300 can be formed on the first bracket 4100, or frames for forming different parts of the opening portion 4300 can be formed on the first bracket 4100 and the second bracket 4200, respectively.

[0165] Figure 25 is a side view showing a first bracket formed with a shield according to an embodiment of the present invention, Figure 26 is a schematic diagram showing light blocked by a shield according to an embodiment of the present invention, Figure 25 and Figure 26 This is an example of a situation viewed in a direction from the second bracket 4200 toward the first bracket 4100 .

[0166] Reference Figure 25 and Figure 26 The shield 4110 may be arranged to be inserted into the shielding hole 2300 when the first bracket 4100 and the second bracket 4200 are assembled, and may play a role in blocking light extracted through the light extraction portion 2312 of the shielding hole 2300 .

[0167] Hereinafter, in the embodiment of the present invention, description will be made by taking the shielding object 4110 inserted into the shielding hole 2300 formed between the first light guide lens 2100 and the second light guide lens 2200 as an example.

[0168] The shield 4110 can not only block unnecessary light in the light incident on the first light guide lens 2100 and the light incident on the second light guide lens 2200, but in an embodiment of the present invention, the shield 4110 can be formed using a non-transmissive material that does not transmit light, can be formed using a black material with high light absorbance, or can be coated with black paint.

[0169] That is, the shielding member 4110 can play the following role: blocking the light L31 of the transmitted light extraction portion 2312 in the light incident on the first light guide lens 2100, and at the same time causing the light extraction portion formed through the shielding hole between the second light guide lens 2200 and the light guide lens adjacent to the lower side of the second light guide lens 2200 to be obliquely reflected in the forward direction to diffuse at least a portion of the light L32 and L33 of the transmitted connecting portion 2320.

[0170] At this time, a blocking wall 4111 may be formed on the upper portion of the shield 4110 to prevent the light L31 transmitted through the light extraction portion 2312 from being transferred to the first emission portion 2120 through the air layer within the shielding hole 2300 .

[0171] In an embodiment of the present invention, the case where the blocking wall 4111 is formed in a roughly "T" shape on the upper part of the shield 4110 is explained as an example. This is to reduce the required material and reduce the total weight compared to the case where the shield 4110 is formed to have an overall roughly triangular shape similar to the shielding hole 2300.

[0172] Furthermore, a plurality of diffusion patterns 4112 for diffusing at least a portion of the light L32 and L33 transmitted through the connecting portion 2320 may be formed on the lower surface of the shield 4110. The plurality of diffusion patterns 4112 are arranged in the front-to-back direction, and each of the plurality of diffusion patterns 4112 may be formed to extend in the left-to-right direction.

[0173] At this time, since the light L32 and L33 transmitting the connection portion 2320 travels obliquely forward, the rear surface of each of the plurality of diffusion patterns 4112 can be formed to gradually tilt forward and downward from the upper end to the lower end, thereby reaching the rear surface of the first diffusion pattern 4112a among the plurality of diffusion patterns 4112 and reaching the front surface of the second diffusion pattern 4112b arranged adjacent to the rear side of the first diffusion pattern 4112a and being reflected at least twice, so that the energy can be reduced.

[0174] At this time, preferably, the front surface of the second diffusion pattern 4112b is formed approximately vertically. This is because, while the light traveling toward the rear surface of the first diffusion pattern 4112a is not interfered with by the second diffusion pattern 4112b, the light reflected by the rear surface of the first diffusion pattern 4112a is reflected again by the front surface of the second diffusion pattern 4112b as much as possible, thereby enabling at least two reflections, and the energy of the light is sufficiently reduced.

[0175] That is, each time the light L32 and L33 transmitted through the connecting portion 2320 is reflected from the multiple diffusion patterns 4112, the energy may be reduced. As the number of times reflected by the multiple diffusion patterns 4112 increases, the energy is further reduced, so that the energy does not have the level of energy capable of generating glare. Therefore, preferably, the size of each of the multiple diffusion patterns 4112 is smaller than the size of the multiple prism patterns 2321 of the connecting portion 2320.

[0176] above Figure 25 and Figure 26 The following case is used as an example for explanation: unnecessary light among the light incident on the second light guide lens 2200 is reflected by the light extraction portion of the shielding hole formed between the second light guide lens 2200 and the light guide lens provided adjacent to the lower side of the second light guide lens 2200, so that the entire connecting portion 2320 is transmitted. However, the present invention is not limited thereto. A portion of the unnecessary light among the light incident on the second light guide lens 2200 may not be transmitted through the connecting portion 2320 and may be reflected. In this case, as shown in FIG. Figure 19 As shown, the light can be diffused by the diffusion portion of the shielding hole formed between the second light guide lens 2200 and the light guide lens adjacent to the lower side of the second light guide lens 2200, thereby preventing glare.

[0177] Furthermore, if there is light L33 in the light L32 and L33 passing through the connecting portion 2320 that is not sufficiently diffused by the multiple diffusion patterns 4112 and travels forward, glare may occur. Therefore, the front end of the diffusion portion 2313 and the front end of the connecting portion 2320 are connected by a curved surface 2313b having a predetermined curvature, thereby diffusing the light whose energy is not sufficiently reduced by the multiple diffusion patterns 4112, thereby preventing glare.

[0178] At this time, in order to sufficiently reduce the energy of light passing through the connecting portion 2320 by the multiple diffusion patterns 4112 , the number of reflections by the multiple diffusion patterns 4112 needs to be increased. Therefore, preferably, the multiple diffusion patterns 4112 are formed at a higher density than the multiple prism patterns 2321 .

[0179] That is, the surface that transmits light in the multiple prism patterns 2321 needs to have an appropriate size according to the amount of light so that the light transmitting the multiple prism patterns 2321 travels along a set path. In contrast, the multiple diffusion patterns 4112 preferably have as high a formation density as possible to increase the number of reflections of the light transmitting the connecting portion 2320. In this case, the formation size and formation spacing of the multiple diffusion patterns 4112 will become smaller than the formation size and formation spacing of the multiple prism patterns 2321, whereby the formation density of the diffusion patterns 4112 will become higher than the formation density of the multiple prism patterns 2321.

[0180] Furthermore, the multiple prism patterns 2321 serve to maintain the travel path of the transmitted light, and the multiple diffusion patterns 4112 serve to reflect the light of the transmission connection portion 2320 between the adjacent diffusion patterns in the multiple diffusion patterns 4112. Therefore, the front surface and the rear surface of each of the multiple diffusion patterns 4112 can have a larger inclination than the surface that transmits the light in the multiple prism patterns 2321.

[0181] In addition, in the vehicle lamp 1 of the present invention, the emission surface 3020 of each of the multiple optical lenses 3000 can be formed to have separate focal points different from each other. This is to not only utilize the light emitted through the corresponding emission surface 3020 of the light incident on the incident surface 3010 of one of the multiple optical lenses 3000, but also to utilize the light emitted through the emission surfaces of other optical lenses adjacent in the up and down directions.

[0182] That is, when light incident on the incident surface 3010 of one of the multiple optical lenses 3000 is emitted through the exit surface of another adjacent optical lens instead of the corresponding exit surface 3020, it is irradiated onto an area that deviates from the beam pattern suitable for the purpose of the vehicle lamp 1 of the present invention, and there is a high possibility of causing dazzle to the driver of the vehicle in front or reducing the driver's forward field of vision. However, in an embodiment of the present invention, the exit surface 3020 of each of the multiple optical lenses 3000 has a separate focus that is different from each other, thereby forming another beam pattern by light incident on the incident surface 3010 of one of the multiple optical lenses 3000 and emitted through the exit surface of another adjacent optical lens in the up and down directions, thereby simultaneously forming different beam patterns without adding an additional optical system.

[0183] Figure 27 is a schematic diagram showing the shapes of the incident surface and the exit surface of a plurality of optical lenses according to an embodiment of the present utility model, Figure 27 This is an example of a case where no step difference is formed between mutually adjacent optical lenses among a plurality of optical lenses.

[0184] Reference Figure 27 The incident surface 3010 of each of the multiple optical lenses 3000 can be gathered to have a shape that is roughly convex toward the rear as a whole and has a shape that is individually concave toward the front, so that the incident surface 3010 of each of the multiple optical lenses 3000 has a common focus, and the exit surface 3020 of each of the multiple optical lenses 3000 can have a shape that is individually convex toward the front and has a shape that is roughly close to a plane as a whole.

[0185] At this time, Figure 27 In the embodiment, inflection points Pi can be formed between the incident surface and the exit surface of the optical lenses adjacent to each other in the multiple optical lenses 3000, respectively. This is because the incident surface of each of the multiple optical lenses 3000 can be formed into a shape that is individually concave toward the front, and the exit surface of each of the multiple optical lenses 3000 can be formed into a shape that is individually convex toward the front.

[0186] In the embodiment of the present utility model, as Figure 24 As shown, with the second reference line R2 parallel to the front-to-back direction and passing through the center of the light-guiding lens 2000 in the up-down direction as a reference, the closer the optical lens located on the upper side and the optical lens located on the lower side are to the second reference line R2, the closer the inclinations G1 and G2 at the position where the optical axis Ax of the corresponding light source intersects the incident surface 3010 can be changed to be closer to the vertical line. Therefore, the incident surface 3010 of each of the multiple optical lenses 3000 can have a shape that is roughly convex toward the rear as a whole.

[0187] In other words, the more the inclination G1 of the incident surface of the optical lens located on the upper side with the second reference line R2 as the reference among the multiple optical lenses 3000 is separated by a larger interval along the upper side, the more it is inclined at a larger angle in the direction toward the front with the vertical line as the reference. On the contrary, the more the inclination G2 of the incident surface of the optical lens located on the lower side with the second reference line R2 as the reference among the multiple optical lenses 3000 is separated by a larger interval along the lower side, the more it is inclined at a larger angle in the direction toward the rear with the vertical line as the reference, and the closer it is to the second reference line R2, the closer it is to the vertical line. Therefore, the incident surface 3010 of each of the multiple optical lenses 3000 has a shape that is generally convex toward the rear, so that a common focus can be formed by the corresponding light-guiding lenses and optical lenses in the multiple light-guiding lenses 2000 and the multiple optical lenses 3000.

[0188] At this time, in the case where the inclination has a larger angle in the forward or backward direction, the case where the inclination is at the upper portion with respect to the optical axis Ax of the corresponding light source will be described as an example.

[0189] Furthermore, in an embodiment of the present invention, the inclinations at the positions where the optical axes Ax of the corresponding light sources intersect with the exit surfaces 3020 are similar to each other as a whole, so the exit surfaces 3020 of each of the multiple optical lenses 3000 can be understood as having a roughly planar shape as a whole.

[0190] As described above, the incident surface 3010 of each of the multiple optical lenses 3000 has a shape that is roughly convex toward the rear as a whole, and the exit surface 3020 of each of the multiple optical lenses 3000 has a roughly flat shape as a whole. It can be understood that the degree of change in the inclination of the exit surface 3020 of each of the multiple optical lenses 3000 is smaller than the degree of change in the inclination of the incident surface 3010 of each of the multiple optical lenses 3000.

[0191] When the emission surface 3020 of each of the multiple optical lenses 3000 forms a common focus in the same way as the incident surface 3010, light can be prevented from being irradiated in unnecessary directions. However, when the emission surface 3020 of each of the multiple optical lenses 3000 has a predetermined appearance design according to customer requests, etc., it is actually difficult to adjust the curvature, etc. of the emission surface 3020 of each of the multiple optical lenses 3000. Therefore, by adjusting the position of the common focus formed by the emission portions 2020 of the multiple light-guiding lenses 2000 and the incident surfaces 3010 of the multiple optical lenses 3000, not only the light emitted through the corresponding emission surface 3020 of the light incident on the incident surface 3010 of one of the multiple optical lenses 3000 can be utilized, but also the light emitted through the emission surfaces of other optical lenses adjacent in the up and down directions can be utilized.

[0192] Figure 28 is a schematic diagram showing a path of light incident on a first optical lens among a plurality of optical lenses according to an embodiment of the present invention, Figure 29 2 is a schematic diagram illustrating a beam pattern formed by light incident on a first optical lens among a plurality of optical lenses according to an embodiment of the present invention.

[0193] Reference Figure 28 and Figure 29 , multiple optical lenses 3000 may include a first optical lens 3100, a second optical lens 3200 arranged adjacent to the upper side of the first optical lens 3100, and a third optical lens 3300 arranged adjacent to the lower side of the first optical lens 3100, wherein each of the first optical lens 3100, the second optical lens 3200 and the third optical lens 3300 may include an incident surface 3110, 3210, 3310 and an exit surface 3120, 3220, 3320.

[0194] At this time, the first optical lens 3100, the second optical lens 3200 and the third optical lens 3300 are collectively referred to as three optical lenses arranged adjacent to each other in the up and down directions among the multiple optical lenses 3000. Even if one of the second optical lens 3200 and the third optical lens 3300 is formed based on the first optical lens 3100, it can be similarly applied.

[0195] The light L41, L42, L43 incident on the incident surface 3110 of the first optical lens 3100 can be emitted not only through the emission surface 3120 of the first optical lens 3100, but also through the emission surfaces 3320 of the second optical lens 3200 and the third optical lens 3300.

[0196] like Figure 8 As shown, light L41 emitted to the emission surface 3120 of the first optical lens 3100 among the light incident to the incident surface 3110 of the first optical lens 3100 may form a low beam pattern as the first beam pattern P1.

[0197] The light L42 incident on the incident surface 3110 of the first optical lens 3100 and emitted through the lower end of the exit surface 3220 of the second optical lens 3200 can be regarded as traveling and emitting through the lower space with the individual focus of the exit surface 3220 of the second optical lens 3200 as the reference, and thus can be refracted relatively upward to form a second beam pattern P2 on the upper side of the first beam pattern P1. The second beam pattern P2 can be understood as being formed by overlapping the light emitted from each of the multiple optical lenses 3000.

[0198] The light L43 incident on the incident surface 3110 of the first optical lens 3100 and emitted through the upper end of the exit surface 3220 of the third optical lens 3300 can be regarded as traveling and emitting through the lower space with the individual focus of the exit surface 3220 of the third optical lens 3300 as the reference, and thus can be refracted relatively upward to form a third beam pattern P3 on the lower side of the first beam pattern P1. Similar to the second beam pattern P2, the third beam pattern P3 can be understood as being formed by overlapping the light emitted from each of the multiple optical lenses 3000.

[0199] In an embodiment of the present invention, the following situation will be used as an example for explanation: the second beam pattern P2 is a signal beam pattern that can easily confirm the road signs and the like located on the upper side based on the driver's line of sight, and the third beam pattern P3 is a reinforced beam pattern that strengthens the lower end of the low beam pattern to improve the field of vision. However, this is only an example to help understand the present invention and is not limited to this. The types of the second beam pattern P2 and the third beam pattern P3 can be changed in various ways according to the light distribution characteristics of the beam pattern (that is, the area, size, shape, brightness, etc. of the light irradiation).

[0200] At this time, the positions at which the second beam pattern P2 and the third beam pattern P3 are formed may be different according to the position (i.e., focal length) of the individual focus of each of the multiple optical lenses 3000, and the individual focus of each of the multiple optical lenses 3000 may be different according to the position of the above-mentioned common focus.

[0201] In other words, the longer the focal length of the emission surface 3020 of each of the multiple optical lenses 3000, the closer the second beam pattern P2 and the third beam pattern P3 can be formed at a position in the vertical direction to the cut-off line CL. Conversely, the shorter the focal length, the farther away from the cut-off line CL they are formed at in the vertical direction.

[0202] As described above, in the embodiment of the present invention, the individual focal points of each of the emission surfaces 3020 of each of the plurality of optical lenses 3000 are made different from each other, thereby simultaneously forming different beam patterns without adding a separate optical system.

[0203] In addition, in the above embodiment, although the following case is described as an example: unnecessary light is blocked by the shielding material 4110 inserted into the shielding hole 2300 formed between the first light guide lens 2100 and the second light guide lens 2200 disposed adjacent to each other in the vertical direction, since the light guide lens located on the uppermost side of the plurality of light guide lenses 2000 cannot have a shielding hole formed on its upper side, Figure 30 and Figure 31 As shown, in the first bracket 4100 and the second bracket 4200, diffusion patterns 4410 and 4420 for diffusing light may be formed on at least a portion of the surface facing the upper surface of the light guide lens located at the uppermost end of the plurality of light guide lenses 2000. Figure 23 As shown, a diffusion pattern 4430 for diffusing light may also be formed on the upper surface of the light guide lens located at the uppermost end among the plurality of light guide lenses 2000 .

[0204] As described above, the vehicle lamp 1 of the present invention can not only utilize the exit surface corresponding to the light incident on the incident surface of each of the multiple optical lenses 3000, but can also utilize the light emitted from other adjacent optical lenses to simultaneously form different beam patterns from each other. Therefore, there is no need to increase the use of components for forming different beam patterns from each other, thereby reducing the number of components and saving costs.

[0205] As described above, in the vehicle lamp 1 of the present invention, even if a plurality of light-guiding lenses 2000 are formed integrally with each other, unnecessary light in the light incident from each of the plurality of light-guiding lenses 2000 can be prevented from being emitted, thereby achieving a slim appearance design, and preventing light from irradiating unnecessary areas to cause glare or reduced field of view, thereby forming an optimal beam pattern.

[0206] Those with ordinary knowledge in the technical field to which this utility model belongs will surely understand that this utility model can be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above are illustrative in all aspects and should be understood as non-limiting embodiments. The scope of this utility model is not limited by the foregoing detailed description, but by the claims. All changes or modifications that can be derived from the meaning, scope and equivalent concepts of the claims should be interpreted as included in the scope of this utility model.
