Description

Technical Field

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

[0002] Generally, a vehicle has a plurality of lamps including a lighting function for making it easier to identify objects around the vehicle when the vehicle is traveling at night and a signaling function for notifying other vehicles or road users of the vehicle's traveling status.

[0003] For example, headlights and fog lights are mainly intended for lighting, while turn signals, taillights and brake lights are mainly intended for signaling. The setting criteria and specifications of each lamp have been stipulated through laws and regulations so that their respective functions can be fully utilized.

[0004] Recently, in addition to the functional aspect of assisting safe driving by ensuring the driver's visibility, which is the basic role of vehicle lamps, the aesthetic aspect of consumers' perception through improved exterior design has also had a great influence on whether to decide whether to purchase a vehicle.

[0005] For this reason, research is actively underway into a vehicle lamp that can achieve a slim design while forming an optimal beam pattern.

[0006] [Prior art literature] [Patent Literature] Korean Patent Publication No. 10-2021-0045730 (published on April 27, 2021) Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle lamp that prevents light from irradiating unnecessary areas when light emitted from multiple light sources passes through multiple light guide lenses and is irradiated by multiple optical lenses to form a beam pattern.

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

[0009] In order to achieve the above technical problems, a vehicle lamp according to an embodiment of the present invention may include: a plurality of light sources arranged in an up-down direction; and a plurality of light-guiding lenses located in front of the plurality of light sources so that light emitted from the plurality of light sources is incident, wherein the plurality of light-guiding lenses may be integrally formed along the arrangement direction of the plurality of light sources.

[0010] Each of the plurality of light-guiding lenses may include: an incident portion, into which light emitted from a corresponding light source among the plurality of light sources is incident; an emitting portion, located in front of the incident portion, to emit the incident light; and a transmitting portion, to transmit at least a portion of the light incident on the incident portion to the emitting portion.

[0011] The incident portion may include: a central surface centered on the optical axis of a corresponding light source among the multiple light sources; a protruding surface formed to protrude from an edge of the central surface toward the corresponding light source; and a reflecting surface that reflects light incident on the protruding surface in a manner that moves toward the emitting portion.

[0012] The plurality of light guide lenses may include: a first light guide lens and a second light guide lens disposed adjacent to each other along an arrangement direction of the plurality of light sources, wherein a shielding hole is formed between the first light guide lens and the second light guide lens to block a portion of light incident to the first light guide lens.

[0013] The shielding hole may include: a shielding portion having a rear focus of an emission portion of light emitted 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.

[0014] The shielding portion may include: a shielding reflection portion, which is formed to tilt downwardly in the rear direction from the front end located at the rear side focus of the emitting portion; a light extraction portion, which is formed to tilt downwardly in the rear direction from the rear end of the shielding reflection portion; and a diffusion portion, which is formed to tilt downwardly in the front direction in front of the shielding reflection portion.

[0015] The shielding reflection portion may reflect light reaching a predetermined area at the rear with reference to a rear focal point of the emitting portion so as to travel toward the emitting portion.

[0016] The shielding reflection part can be formed with a step difference based on the center part, so that the two sides have different heights from each other, wherein the shielding part can also include: an extension part, which is formed to be inclined downward from the front end of the shielding reflection part to the front direction, so that the step difference extends to a predetermined area in front of the shielding reflection part.

[0017] 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 set path by at least one of transmission and reflection.

[0018] The light transmitted through the light extraction portion may be blocked from traveling toward the emission portion of the first light guide lens by a shielding object inserted and disposed in the shielding hole.

[0019] At least a portion of the light reflected by the light extraction portion can travel through a surface of a shielding hole formed between the first light guide lens and a light guide lens adjacent to the upper side of the first light guide lens, so that at least a portion of the light reflected by the light extraction portion is blocked by a shielding object inserted into the shielding hole formed between the first light guide lens and the light guide lens adjacent to the upper side of the first light guide lens.

[0020] At least a portion of the light reflected by the light extraction portion may be reflected by a surface of a shielding hole formed between the first light guide lens and a light guide lens adjacent to the upper side of the first light guide lens in a manner of moving obliquely downward toward the front so as to be diffused by the diffusion portion.

[0021] The front end of the shielding portion and the front end of the connecting portion may be connected via a curved surface having a predetermined curvature so as to diffuse light.

[0022] The connection portion may include a plurality of prism patterns to allow a portion of light incident on the second light guide lens to travel toward a shielding object inserted and disposed in the shielding hole.

[0023] The size of each of the plurality of prism patterns may be determined according to the amount of light transmitted through the connection portion, and any one of the plurality of prism patterns may have a size different from another one of the plurality of prism patterns.

[0024] The connection portion may be formed in a region within a set interval in a direction from an upper surface toward a lower surface of the second light guide lens, the set interval being less than 25% of a total interval between the upper surface and the lower surface of the second light guide lens.

[0025] The light guide lens located at the lowermost end among the plurality of light guide lenses may include a shielding portion formed concavely on a lower surface to block a portion of the emitted light.

[0026] Details of other embodiments are included in the detailed description and drawings.

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

[0028] 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 beam pattern's bright and dark cutoff lines while preventing light from irradiating unnecessary areas.

[0029] Moreover, since a common focal point can be formed based on the directions in which the centerlines of the light-emitting portions of the plurality of light guide lenses are inclined and the directions in which the curvatures of the upper and lower directions of the incident surfaces of the plurality of optical lenses are inclined, the following effect is achieved: Even when the light emitted from each of the plurality of light guide lenses is incident not only on the corresponding optical lens among the plurality of optical lenses but also on another adjacent optical lens, it is possible to prevent the light from irradiating an unnecessary area.

[0030] 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 not mentioned from the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS

Throughout the specification, the same figure numerals refer to the same components.

[0061] Hereinafter, the present invention will be described based on the embodiments of the present invention by referring to the accompanying drawings for describing a vehicle lamp.

[0062] 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 rear view showing a vehicle lamp according to an embodiment of the present invention, Figure 5 and Figure 6 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 profile, Figure 7 This is an example in which the mounting bracket 4000 is omitted.

[0063] 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 a mounting bracket 4000 .

[0064] In an embodiment of the present invention, the vehicle lamp 1 is explained by taking the following situation as an example: when the vehicle is driving at night, the headlight is used to irradiate light in the driving direction 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-right direction, indicating the width direction of the vehicle, the Y-axis direction is the front-back direction, indicating the driving direction, and the Z-axis is the up-down direction, indicating the height direction of the vehicle, but it is not limited to this. According to the position or direction in which the vehicle lamp 1 of the present invention is set, the directions actually represented by the X-axis, Y-axis and Z-axis can be changed.

[0065] 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, fog lights, reversing lights, and position lights.

[0066] 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. The low beam pattern irradiates light downward based on the light-dark cutoff line to prevent glare to the driver of a vehicle in front, such as a preceding vehicle or an oncoming vehicle, so as to ensure a wide field of view in the short distance in front of the vehicle. The high beam pattern ensures a long field of view in the long distance in front of the vehicle. In the following, in the embodiments of the present invention, the following case will be taken as an example 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.

[0067] The plurality of light sources 1000 can generate light having a light quantity or a color suitable for the application of the vehicle lamp 1 of the present invention.

[0068] In an embodiment of the present invention, a case where a plurality of light sources 1000 are arranged in the up-down direction and further moved toward one side in the left-right direction from the upper side toward the lower side is described as an example, so that the plurality of light sources 1000 are formed along the main body line of the vehicle.

[0069] For example, the vehicle lamp 1 of the present invention can be configured to be accommodated 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.

[0070] In other words, in the case where the cover lens has a planar 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 planar or curved shape formed obliquely relative to the front, the plurality of light sources 1000 can be arranged from one side to the other in the up-down direction and further moved toward one side in the left-right direction.

[0071] The situation where the plurality of light sources 1000 are arranged along the body line of the vehicle can be understood as the plurality of light guide lenses 2000 and the plurality of optical lenses 3000 being similarly arranged along the body line of the vehicle, and a detailed description of this will be given later.

[0072] 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 in one direction, the vehicle lamp 1 of the present invention can achieve a slim appearance design in one direction, thereby improving the aesthetic sense.

[0073] 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 a plurality of light sources 1000 is described as an example, but the invention is not limited thereto. The plurality of light sources 1000 may use not only LEDs but also various types of light sources such as laser diodes (LD) or light bulbs, and optical elements such as reflectors, prisms, mirrors, phosphors, etc. for adjusting the path, brightness, color, etc. of light may be additionally used depending on the type of light source.

[0074] Fig. 9 is a front view showing a plurality of light guide lenses according to an embodiment of the present invention, Fig.10 is a rear view showing a plurality of light guide lenses according to an embodiment of the present invention, Fig.11 is a side view showing a plurality of light guide lenses according to an embodiment of the present invention, Fig.12 yes Fig. 9 The B-B' line profile, Fig.13 yes Fig.11 The C-C' line profile, Fig.14 2 is a rear view showing a first light guide lens and a second light guide lens according to an embodiment of the present invention.

[0075] Reference Figures 9 to 14 , each of the plurality of light guide lenses 2000 according to an embodiment of the present invention 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.

[0076] 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 moving further toward one side in the left-right direction from one side to the other side due to similar reasons as the plurality of light sources 1000 .

[0077] 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 into the incident portion 2010; and a transmitting portion 2030, for transmitting at least a portion of the light incident into the incident portion 2010 to the emitting portion 2020.

[0078] 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 light sources of the plurality of light sources 1000 .

[0079] 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 assembling process may be simplified.

[0080] 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.

[0081] 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.

[0082] 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, 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.

[0083] The multiple light guide lenses 2000 can be formed so that the lower the light guide lenses are, the longer the 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 more the multiple optical lenses 3000 are arranged from the upper side to the lower side, the closer they are to the front.

[0084] That is, in a case where a plurality of optical lenses 3000 are located in the front along the main body line of the vehicle from the upper side to the lower side, the light guide lens located at the lower side among the plurality of light guide lenses 2000 needs to have the emission portion 2020 located in the front, and in a case where a plurality of 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 guide lens located at the lower side among the plurality of light guide lenses 2000 has a longer length in the front-to-back direction so that the emission portion 2020 is located in the front.

[0085] At this time, the reason why the plurality of light sources 1000 are provided on a common substrate is that the number of parts is reduced compared to the case where a separate individual substrate is used for each of the plurality of light sources 1000, so that the cost can be reduced and the assembly process can be simplified.

[0086] The multiple light guide lenses 2000 may include a first light guide lens 2100 and a second light guide lens 2200 located at the lower side of the first light guide lens 2100. Below, in the embodiments of the present invention, the following situation will be taken as an example for description: the first light guide lens 2100 and the second light guide lens 2200 are a general term for two light guide lenses that are formed as a whole in a manner of being arranged adjacent to each other along the up and down directions among the multiple light guide lenses 2000.

[0087] The first light guide lens 2100 may include a first incident portion 2110 , a first emission portion 2120 , and a first transmission portion 2130 .

[0088] The first incident portion 2110 may play a role in focusing light incident from a corresponding first light source 1100 among the plurality of light sources 1000 at or near a rear focus F1 of the first emission portion 2120 .

[0089] At this time, the rear focus F1 of the first emitting portion 2120 may have a shape of a point, line, surface, space or a combination thereof according to the actual focusing area. In the following, in an embodiment of the present invention, an example will be taken where the focus has a shape of a point, line, surface, space or a combination thereof similar to the rear focus F1 of the first emitting portion 2120.

[0090] 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 to make it move toward the first emitting portion 2120, wherein the first reflecting surface 2113 may 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.

[0091] At this time, at least a portion of the first reflecting surface 2113 may be formed with a first corrosion portion 2113a, and the first corrosion portion 2113a may prevent at least a portion of unnecessary light in the light incident on the first protruding surface 2112 from being reflected by the first reflecting surface 2113, so that the light is transmitted to the outside of the first light-guiding lens 2100 and travels, thereby playing a role in pre-removing unnecessary light that may cause glare, etc.

[0092] In an embodiment of the present invention, the first corrosion portion 2113a can be formed in at least one of the upper and lower parts based on the optical axis Ax1 of the first light source 1100, and various changes can be made to the area where the first corrosion portion 2113a is formed in at least one of the upper and lower parts of the first reflecting surface 2113.

[0093] The first transmission portion 2130 may function to transmit at least a portion of the light incident on the first incident portion 2110 to the first emission portion 2120 .

[0094] At this time, since the first incident part 2110 and the first emission part 2120 can be connected by the first transfer part 2130 and formed integrally with each other, the number of parts can be reduced and the assembly process can be simplified compared with the case where the first incident part 2110 and the first emission part 2120 are formed and assembled separately.

[0095] 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 .

[0096] 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.

[0097] The second central plane 2211 , the second protruding surface 2212 and the second reflecting surface 2213 are different from the 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 roles will be omitted.

[0098] Furthermore, similar to the above-mentioned first reflecting surface 2113, the second reflecting surface 2213 may be formed with a second corrosion portion 2213a, and the second corrosion portion 2213a may 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 the light is transmitted to the outside of the first light-guiding lens 2200 and travels, thereby playing a role in pre-removing unnecessary light that may cause glare, etc.

[0099] 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. Fig.14 This is an example of a case where the formation positions and formation areas of the first corrosion portion 2113a and the second corrosion portion 2213a are different.

[0100] Similar to the first incident portion 2110 , the second incident portion 2210 may function to focus light incident from a corresponding second light source 1200 among the plurality of light sources 1000 at or near the rear focus F2 of the second emission portion 2220 .

[0101] In addition, in order to form a Figure 8 The low beam pattern P needs 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.

[0102] 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 is taken as an example for description, but it 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.

[0103] The shielding hole 2300 may be formed such that the size of the hole gradually increases along a direction in which a mold is separated during injection molding of the plurality of light guide lenses 2000 , thereby preventing undercut from occurring during injection molding of the plurality of light guide lenses 2000 .

[0104] The shielding hole 2300 may include a shielding portion 2310 and a connecting portion 2320 .

[0105] 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 2120 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 has a roughly triangular shape as a whole, 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 means of the shielding portion 2310 by omitting the connecting portion 2320 from the shielding hole 2300.

[0106] The shielding portion 2310 may include a shielding reflection portion 2311 , a light extraction portion 2312 , and a diffusion portion 2313 .

[0107] The shielding reflection portion 2311 can be formed to be inclined downward toward the rear from the front end located at or near the rear focus F1 of the first emission portion 2120, 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.

[0108] 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 bright and dark 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: Fig.13 As shown, the front end of the shielding reflection portion 2311 is stepped so that both sides have different heights relative to the center portion in the left-right direction.

[0109] At this time, the shielding reflection part 2311 is formed to have a step difference in the left and right directions. 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 it 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.

[0110] In an embodiment of the present invention, the case where the size of the shielding hole 2300 has a larger size 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.

[0111] 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 part of the light passing through the rear focus F1 may be blocked. Therefore, an extension portion 2311a tilted 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: Fig.15 The effect shown is to extend the step difference of the shielding reflection portion 2311 to a predetermined area in front of the shielding reflection portion 2311.

[0112] The above-mentioned shielding reflection portion 2311 can be formed to be inclined downward toward the rear with the front end as a 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 emitting portion 2120 and travels is reflected toward the first emitting 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.

[0113] That is, the first light source 1100 may substantially 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.

[0114] At this time, since the light gathered at 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 reflection portion 2311. Fig.16 As shown, among the lights 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.

[0115] 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 can proceed to the first emission portion 2120 without being blocked based on the rear focus F1 in the propagation surface. On the contrary, the area located at the rear is blocked based on the rear focus F1 in the propagation surface, so that light loss may occur. Therefore, it is reflected by the shielded reflection portion 2311 and can proceed to 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.

[0116] The light extraction portion 2312 may be located behind the shielding reflection portion 2311 , and thus may play a role in extracting unnecessary light among the light incident on the first incident portion 2110 in a manner that the light travels along a set path.

[0117] 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.

[0118] 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 taken as an example for explanation: Fig.17 As shown, the light extraction portion 2312 allows the light L21, L22 that causes glare, etc., among 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.

[0119] For example, Fig.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 the unnecessary area P', which may cause glare 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 a set path, thereby preventing the unnecessary area P' from being illuminated in advance.

[0120] 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 toward the rear will be described as an example, but it is not limited to this. According to the path of the light extracted by the light extraction portion 2312, the formation angle or size of the light extraction portion 2312 can be changed in various ways.

[0121] In addition, although the case in which 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 a plurality of light guide lenses 2000 in one piece.

[0122] 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.

[0123] like Fig.19 As shown, the diffusion portion 2313 may include: at least one diffusion pattern 2313a, which is used to diffuse the light L22 reflected by the light extraction portion 2312 and traveling toward the front direction, 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.

[0124] 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 another 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 the generation of glare, etc.

[0125] 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, and 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 guide lens 2200 and the light guide lens adjacent to the lower side of the second light guide lens 2200 and transmits 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.

[0126] 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.

[0127] At this time, 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.

[0128] In other words, when a plurality of prism patterns with relatively small sizes are formed at positions in the connecting portion 2320 where a relatively large amount of light is transmitted, it is relatively difficult to control the paths of light that transmits each of the plurality of prism patterns. Therefore, the size of the prism pattern can be increased to facilitate control of the path of light, wherein the size of each of the plurality of 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.

[0129] like Fig. 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 d' exceeding 25% 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 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 than the upper surface of the second light guide lens 2200 (i.e., 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 to the connecting portion 2320, and the path of the light becomes longer, making it difficult to control the path of the light, which may cause glare.

[0130] The plurality of optical lenses 3000 may play a role of transmitting light emitted from corresponding light guide lenses among the plurality of light guide lenses 2000 to form a beam pattern suitable for the purpose of the vehicle lamp 1 according to the present invention.

[0131] Fig.21 and Fig. 22 is a perspective view showing a plurality of optical lenses according to an embodiment of the present invention.

[0132] Reference Fig.21 and Fig. 22 , the plurality of optical lenses 3000 may be integrally formed along the up-down direction similar to the plurality of light guide lenses 2000, and may be inclinedly formed in such a manner that the plurality of optical lenses 3000 are further moved toward one side along the left-right direction from the upper side toward the lower side.

[0133] In an embodiment of the present invention, a case where each of the multiple optical lenses 3000 is formed in the left-right direction with one side located forward compared to the other side is taken as an example for explanation, which is to be formed along the main body line of the vehicle similarly to the multiple light sources 1000 and the multiple light guide lenses 2000.

[0134] Each of the multiple optical lenses 3000 can make the light incident on the incident surface 3010 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 being concave forward. This is to make 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 have a common focus, and a detailed description of this will be described later.

[0135] In an embodiment of the present invention, in order to easily control the optical path of light transmitted through multiple optical lenses 3000, the case in which the emission surface 3020 includes multiple facets 3021 will be used as an example for explanation, but this is merely an example to help understand the present invention and is not limited to this. In the multiple optical lenses 3000, at least one of the incident surface 3010 and the emission surface 3020 can be composed of multiple facets.

[0136] 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.

[0137] At this time, the reason why the emission portions 2020 of the light guiding lenses corresponding to each other in the plurality of light guiding lenses 2000 and the incident surfaces 3010 of the optical lenses are made to have a common focus is that, when the emission portions 2020 of the light guiding lenses corresponding to each other in the plurality of light guiding lenses 2000 and the incident surfaces 3010 of the optical lenses are made to have separate focal points different from each other, light emitted from each of the plurality of light guiding lenses 2000 will not only be incident on the corresponding optical lens in the plurality of optical lenses 3000, but will also be incident on other adjacent optical lenses, thereby generating glare, etc.

[0138] In order to make the emitting portions 2020 of the light guide lenses 2000 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 described above, Fig.23 As shown, with reference to a horizontal 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, a center line C of the emission portion 2020 of at least one of the plurality of light guide lenses 2000 may be formed to be inclined in a predetermined direction.

[0139] That is, the light guide lenses located on both sides respectively with respect to a horizontal reference line R1 passing through the center of the plurality of light guide 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 horizontal reference line R1, and the center line C of the emission portion 2020 of each of the plurality of light guide lenses 2000 can be understood as an axis that enables the emission portion 2020 to be formed into rotational symmetry.

[0140] For example, the optical axis Ax of the corresponding light source among the multiple light guide lenses 2000 is formed with the horizontal reference line R1 as the reference, and the emission portion 2020 of the light guide lens located on the left side is formed with the center line C toward the horizontal reference line R1 and inclined to the right side by a predetermined angle θ1. On the contrary, the optical axis Ax of the corresponding light source among the multiple light guide lenses 2000 is formed with the horizontal reference line R1 as the reference, and the emission portion 2020 of the light guide lens located on the right side is formed with the center line C toward the horizontal reference line R1 and inclined to the left side by a predetermined angle θ2.

[0141] At this time, the plurality of light-guiding lenses 2000 may be formed to be inclined at different angles from each other according to the distances separated in the left-right direction based on the horizontal reference line R1. As an example, the light-guiding lenses 2000 that are separated at a greater distance from the horizontal reference line R1 in the up-down direction may have the emission portion 2020 formed to be inclined at a greater angle.

[0142] Furthermore, in order to make the emitting portions 2020 of the light guide lenses 2000 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. Fig.24 As shown, with a vertical reference line R2 which is parallel to the front-to-back direction and passes 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 respectively located on the upper and lower sides can be formed with a curvature in the up-down direction, with a vertical line which passes vertically through the optical axis Ax of the light source corresponding to each of the multiple light sources 1000 and corresponds to the multiple light-guiding lenses 2000 as a reference, and is inclined toward one of the two sides.

[0143] That is, the incident surface 3010 of the optical lens located on the upper side with respect to the vertical 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 vertical 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.

[0144] At this time, the curvature Rv of the incident surface 3010 of the optical lens located on the upper side with the vertical 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 vertical reference line R2 as the reference is inclined toward the left side with the vertical line Lv as the reference. This is because, as Fig.23 As shown, the optical axis Ax of the corresponding light source in the optical lens located on the upper side with respect to the vertical reference line R2 is located on the left side with respect to the horizontal reference line R1, and the optical axis Ax of the corresponding light source in the optical lens located on the lower side with respect to the vertical reference line R2 is located on the right side with respect to the horizontal reference line R1.

[0145] As described above, the center line C of the emission portion 2020 of the plurality of light-guiding lenses 2000 is tilted in the left-right direction with reference to the horizontal reference line R1, and the curvature Rv in the up-down direction of the incident surface 3010 of each of the plurality of optical lenses 3000 is tilted in the left-right direction with reference to the vertical line Lv. This is because a common focus is formed by combining the emission portion 2020 of each of the plurality of light-guiding lenses 2000 and the incident surface 3010 of the optical lens corresponding to each of the plurality of optical lenses 3000. Accordingly, even if the light emitted from each of the plurality of light-guiding lenses 2000 is incident not only on the corresponding optical lens in the plurality of optical lenses 3000 but also on another adjacent optical lens, it can travel in the form of parallel light, thereby preventing glare.

[0146] 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 located in the shield hole 2300 formed between the first light guide lens 2100 and the second light guide lens 2200 .

[0147] 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, and 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 at the other side of the plurality of light guide lenses 2000, so that the mutual positions can be fixed.

[0148] 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 as to be 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.

[0149] When assembling the first bracket 4100 and the second bracket 4200, the mounting bracket 4000 may be formed with an opening portion 4300 corresponding to the plurality of optical lenses 3000, thereby preventing light emitted from the plurality of light sources 1000 from leaking during the process of transmitting through the plurality of optical lenses 3000 after passing through the plurality of light guide lenses 2000.

[0150] In an embodiment of the present invention, the case where the frame 4310 for forming the opening portion 4300 is integrally formed with the second bracket 4200 is taken 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.

[0151] Fig.25 is a side view showing a first bracket formed with a shield according to an embodiment of the present invention, Fig.26 is a schematic diagram showing light blocked by a shield according to an embodiment of the present invention, Fig.25 and Fig.26 This is an example of a case where the display is viewed in a direction from the second bracket 4200 toward the first bracket 4100 .

[0152] Reference Fig.25 and Fig.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 .

[0153] Hereinafter, in the embodiment of the present invention, 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 will be described as an example.

[0154] The shield 4110 may play a role of blocking not only unnecessary light among the light incident to the first light guide lens 2100 and the light incident to the second light guide lens 2200 .

[0155] That is, the shielding 4110 can play the following role: blocking the light L31 of the transmitted light extraction portion 2312 of the light incident on the first light guide lens 2100, and at the same time diffusing at least a portion of the light L32 and L33 of the transmitted connecting portion 2320 by being obliquely reflected in the forward direction through 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.

[0156] At this time, a blocking wall 4111 may be formed on an 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 .

[0157] In an embodiment of the present invention, a case where a blocking wall 4111 is formed in a substantially "T" shape on the upper portion of the shield 4110 is taken as an example for explanation. This is to reduce the required material and reduce the total weight compared to a case where the shield 4110 is formed to have an overall substantially triangular shape similar to the shielding hole 2300.

[0158] In addition, a plurality of diffusion patterns 4112 may be formed on the lower surface of the shield 4110 to diffuse at least a portion of the light L32 and L33 passing through the connecting portion 2320 , thereby preventing glare and the like from being generated.

[0159] At this time, 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. Accordingly, the light whose energy is not sufficiently reduced is diffused by the multiple diffusion patterns 4112, thereby preventing glare.

[0160] Above Fig.25 and Fig.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 disposed adjacent to the lower side of the second light guide lens 2200, so that the entire connecting portion 2320 is transmitted, but it is not limited to this. A part 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 be reflected. In this case, as Fig.19 As shown, the light reflected by the connection portion 2320 is diffused in the diffusion portion 2313, thereby preventing glare from being generated.

[0161] In addition, in the above-mentioned 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 up-down direction, since the light guide lens located at the uppermost side among the plurality of light guide lenses 2000 cannot form a shielding hole on its upper side, Fig. 27 and Fig.28 As shown, in the first bracket 4100 and the second bracket 4200, 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 may be formed with diffusion patterns 4410 and 4420 for diffusing light. Fig.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 .

[0162] 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.

[0163] Personnel with ordinary knowledge in the technical field to which the present invention belongs must understand that the present invention can be implemented in other specific forms without changing its technical ideas or essential features. Therefore, the embodiments described above are exemplary in all aspects and should be understood to be non-limiting embodiments. The scope of the present invention is not limited by the aforementioned detailed description, but by the claims, and all changes or deformations that can be derived from the meaning, scope and equivalent concepts of the claims should be interpreted as being included in the scope of the present invention.
