Description

car lamps

[0001] The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp that enables the implementation of a slim exterior design while preventing light from being irradiated in unnecessary directions.

[0002] Typically, vehicles are equipped with various types of vehicle lamps that have a lighting function to easily identify objects located around the vehicle when driving at night and a signaling function to inform other vehicles and road users of the vehicle's driving status.

[0003] For example, headlamps and fog lamps are primarily intended for lighting purposes, while turn signal lamps, tail lamps, brake lamps, etc. are primarily intended for signaling purposes. The installation standards and specifications for these vehicle lamps are stipulated by law to ensure that each function is fully realized.

[0004] Recently, not only the functional aspect of vehicle lamps, which is the basic role of vehicle lamps to ensure driver visibility and thus help drive safely, but also the aesthetic aspect perceived by consumers through design improvements are having a great influence on vehicle purchase decisions.

[0005] To this end, active research is being conducted to improve the exterior design of vehicle lamps by making them slimmer, and by using multiple optical lenses that form micro lenses that are advantageous for miniaturization because they have relatively short focal lengths, a slim exterior design is being implemented while forming an optimal beam pattern.

[0006] At this time, when a beam pattern is formed through multiple optical lenses, it is necessary for adjacent optical lenses among the multiple optical lenses to be spaced apart at a certain interval in consideration of manufacturing tolerances or assembly tolerances, but in this case, light may be irradiated in an unnecessary direction due to the space between adjacent optical lenses, and a sense of disconnection may occur between adjacent optical lenses. Therefore, a method is required that prevents light from being irradiated in an unnecessary direction and a sense of disconnection from occurring between adjacent optical lenses while implementing a slim exterior design.

[0007] The problem to be solved by the present invention is to provide a vehicle lamp in which a slim exterior design can be realized by arranging a plurality of optical lenses, while preventing light from being irradiated in an unnecessary direction by a space between adjacent optical lenses among the plurality of optical lenses.

[0008] In addition, a vehicle lamp is provided in which a sense of disconnection is prevented from occurring between adjacent optical lenses due to a gap between adjacent optical lenses among a plurality of optical lenses.

[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] In order to achieve the above object, a vehicle lamp according to an embodiment of the present invention comprises: a light source unit including a plurality of light source modules arranged in at least one direction; a first optical unit positioned in front of the light source unit and including a plurality of light path adjustment units for adjusting a path of light incident from each of the plurality of light source modules; and a second optical unit positioned in front of the first optical unit and including a plurality of optical lenses for allowing at least a portion of the light incident from the plurality of light path adjustment units to be emitted, wherein among the plurality of optical lenses, adjacent optical lenses may be positioned to be spaced apart from each other along a direction in which the plurality of light source modules are arranged.

[0011] Each of the plurality of optical lenses may include a light transmitting portion; a plurality of incident lenses arranged on an incident surface of the light transmitting portion; and a plurality of exit lenses arranged on an exit surface of the light transmitting portion.

[0012] Each of the plurality of incident lenses is formed to extend in one direction, and light incident on any one of the plurality of incident lenses can be emitted through two or more adjacent exit lenses among the plurality of exit lenses.

[0013] The light transmitting portion of each of the plurality of optical lenses is formed to be inclined so that one side is positioned forward compared to the other side in at least one direction, and the incident surface and the exit surface of the light transmitting portion of each of the plurality of optical lenses can be positioned on the same plane.

[0014] Each of the plurality of optical lenses may further include a plurality of shields positioned between the plurality of entrance lenses and the plurality of exit lenses to block a portion of light traveling to a corresponding exit lens among the plurality of exit lenses.

[0015] The plurality of optical lenses include a first optical lens and a second optical lens positioned adjacent to each other based on the arrangement direction of the plurality of light source modules, and at least one of a distance between a front end and a rear end of a first opposing surface of the first optical lens facing the second optical lens in the arrangement direction of the plurality of light source modules and a distance between a front end and a rear end of a second opposing surface of the second optical lens facing the first optical lens in the arrangement direction of the plurality of light source modules may be greater than a separation distance between the first optical lens and the second optical lens in the arrangement direction of the plurality of light source modules.

[0016] At least one of the first facing surface and the second facing surface may have a step portion formed between the front end and the rear end, which has a step in the arrangement direction of the plurality of light source modules.

[0017] At least one of the first opposing surface and the second opposing surface may be formed as a sloped surface that is continuously formed without a step between the front end and the rear end.

[0018] Other specific details of the present invention are included in the detailed description and drawings.

[0019] According to the vehicle lamp of the present invention as described above, one or more of the following effects are provided.

[0020] There is an effect that can implement a slim-shaped exterior design by a plurality of optical lenses arranged in at least one direction.

[0021] In addition, since the gap between the front and rear ends of the opposing surfaces between adjacent optical lenses among a plurality of optical lenses is formed to be larger than the gap between adjacent optical lenses, there is also an effect that light is prevented from being irradiated in an unnecessary direction and a sense of disconnection is prevented from occurring between adjacent optical lenses.

[0022] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0043] Hereinafter, the present invention will be described with reference to drawings for explaining a vehicle lamp according to embodiments of the present invention.

[0044] FIG. 1 is a perspective view illustrating a vehicle lamp according to an embodiment of the present invention, FIG. 2 is a side view illustrating a vehicle lamp according to an embodiment of the present invention, FIG. 3 is a front view illustrating a vehicle lamp according to an embodiment of the present invention, FIG. 4 is an exploded view illustrating a side view of a vehicle lamp according to an embodiment of the present invention, and FIG. 5 is an exploded perspective view illustrating a vehicle lamp according to an embodiment of the present invention.

[0045] Referring to FIGS. 1 to 5, a vehicle lamp (1) according to an embodiment of the present invention may include a light source unit (1000), a first optical unit (2000), and a second optical unit (3000).

[0046] In the embodiment of the present invention, the vehicle lamp (1) is used as a head lamp to secure forward visibility by irradiating light in the direction of travel of the vehicle when the vehicle is driven at night or in a dark place such as a tunnel, but the present invention is not limited thereto, and the vehicle lamp (1) of the present invention can be used as various lamps installed in the vehicle, such as a tail lamp, a brake lamp, a fog lamp, a position lamp, a turn signal lamp, a daytime running lamp, a backup lamp, etc., in addition to a head lamp.

[0047] When the vehicle lamp (1) of the present invention is used as a head lamp, at least one of a low beam pattern that ensures a wide field of vision for a short distance in front of the vehicle by irradiating light downward based on a cut-off line so as not to cause glare to the driver of a front vehicle, such as a preceding vehicle or an oncoming vehicle, and a high beam pattern that ensures a long field of vision for a long distance in front of the vehicle by forming at least a portion of the pattern above the low beam pattern, and when the high beam pattern is formed, the low beam pattern is formed together so as to secure a wide field of vision and a long field of vision for the front of the vehicle.

[0048] Hereinafter, in the embodiment of the present invention, a case in which a low beam pattern is formed by a vehicle lamp (1) will be described as an example, and the X-axis direction is a left-right direction and means a vehicle width direction, the Y-axis direction is a front-back direction and means a driving direction, and the Z-axis direction is an up-down direction and means a garage direction. However, the present invention is not limited thereto, and the directions actually meant by the X-axis, Y-axis, and Z-axis may vary depending on the position or direction in which the vehicle lamp (1) of the present invention is installed.

[0049] The light source unit (1000) may include a plurality of light source modules (1100) arranged along at least one direction, and in the embodiment of the present invention, the plurality of light source modules (1100) are arranged in the vertical direction, but are positioned by moving further to one side along the front-back direction from the top to the bottom, and at the same time, are positioned by moving further to one side along the left-right direction. However, this is merely an example to help understanding of the present invention, and is not limited thereto, and the arrangement direction of the plurality of light source modules (1100) may vary depending on the layout or design reasons of the vehicle lamp (1) of the present invention.

[0050] In an embodiment of the present invention, a case in which a plurality of light source modules (1100) are arranged in a vertical direction, but are positioned by moving further forward in the front-back direction from the top to the bottom, and at the same time, are positioned by moving further to the left in the left-right direction, will be described as an example. This is to ensure that the plurality of light source modules (1100) are arranged along the body line of the vehicle.

[0051] That is, the vehicle lamp (1) of the present invention can be accommodated in a space formed by a lamp housing (not shown) and a cover lens (not shown) coupled to the lamp housing, and a plurality of light source modules (1100) are arranged according to the shape of the cover lens forming a part of the body line of the vehicle.

[0052] For example, when the cover lens has a planar shape facing the front of the vehicle, a plurality of light source modules (1100) are arranged in an up-down direction but have the same position in the front-back and left-right directions, whereas when the cover lens has a planar or curved shape inclined at a predetermined angle in at least one direction with respect to the front of the vehicle, a plurality of light source modules (1100) are arranged in an up-down direction but can be positioned by moving further to one side along at least one of the front-back and left-right directions as they go upward or downward.

[0053] In the embodiment of the present invention, a case is described as an example in which the positions of a plurality of light source modules (1100) gradually change from one side to the other in at least one direction along the body line of the vehicle, but the present invention is not limited thereto, and the installation angle of the plurality of light source modules (1100) themselves may be tilted and positioned at a predetermined angle along the body line of the vehicle.

[0054] FIG. 6 is a perspective view illustrating a light source module according to an embodiment of the present invention. FIG. 6 is an example of a case where one light source module among a plurality of light source modules (1100) is illustrated, and the remaining light source modules can be applied similarly with only some differences in installation positions.

[0055] Referring to FIG. 6, each of the plurality of light source modules (1100) according to an embodiment of the present invention may include a substrate (1102) and at least one light source (1104) installed on the substrate (1102).

[0056] In the embodiment of the present invention, a case in which a semiconductor light-emitting element such as an LED (Light Emitting Diode) is used as at least one light source (1104) will be described as an example, but the present invention is not limited thereto. In addition to an LED, various types of light sources such as an LD (Laser Diode) or a bulb may be used as the at least one light source (1104), and depending on the type of light source, components for controlling the color, path, brightness, etc. of light such as a reflector, prism, mirror, or phosphor may be additionally used.

[0057] Additionally, various components such as at least one light source (1104) and a connector (1106) for controlling the operation or supplying power to at least one light source (1104) may be installed on the substrate (1102).

[0058] Each of the plurality of light source modules (1100) described above can be installed on a corresponding mounting surface among the plurality of mounting surfaces (4100) formed on the heat sink (4000) so that the high temperature heat generated together when light is emitted from at least one light source (1104) is quickly released, because the light-emitting performance of at least one light source (1104) can rapidly deteriorate when the temperature rises due to the high temperature heat generated together when light is emitted from at least one light source (1104).

[0059] At this time, each of the plurality of light source modules (1100) can be mounted on a corresponding mounting surface among the plurality of mounting surfaces (4100) by various methods such as screw coupling, hook coupling, force fitting, adhesive, etc.

[0060] The first optical unit (2000) is positioned in front of the light source unit (1000) and can serve to adjust the path of light so that light emitted forward from the light source unit (1000) and incident thereon enters the second optical unit (3000) with as little loss as possible.

[0061] The first optical unit (2000) may include a plurality of light path adjustment units (2100) arranged along the arrangement direction of the plurality of light source modules (1100), and the plurality of light path adjustment units (2100) may have positions that gradually change from one side to the other in at least one direction, similar to the plurality of light source modules (1100) described above, or the self-installation angles of the plurality of light path adjustment units (2100) may be tilted and positioned.

[0062] For example, the plurality of light path adjustment units (2100) may be positioned by moving further forward in the front-back direction from the top to the bottom, similar to the plurality of light source modules (1100) described above, and at the same time, moving further to the left in the left-right direction.

[0063] Each of the plurality of light path adjustment units (2100) may have a function of converting light emitted from at least one light source (1104) of a corresponding light source module among the plurality of light source modules (1100) at a predetermined light irradiation angle and incident on the incident surface (2110) into approximately parallel light and emitting it through the emission surface (2120), as shown in FIG. 7.

[0064] In the embodiment of the present invention, an example will be described in which an aspherical lens having an incident surface (2110) having a planar shape and an exit surface (2120) having a forward convex shape is used as a plurality of light path adjustment units (2100), but the present invention is not limited thereto, and the plurality of light path adjustment units (2100) may be various types of optical elements such as not only aspherical lenses but also reflectors, Fresnel lenses, and TIR (Total Internal Reflection) lenses that convert light emitted from each of the plurality of light source modules (1100) into approximately parallel light.

[0065] The second optical unit (3000) can serve to transmit at least a portion of the light emitted from the first optical unit (2000) to form a beam pattern suitable for the use of the vehicle lamp (1) of the present invention.

[0066] The second optical unit (3000) may include a plurality of optical lenses (3100) arranged along the arrangement direction of the plurality of light source modules (1100), similar to the plurality of light path adjustment units (2100). Since the light incident on each of the plurality of light path adjustment units (2100) is converted into parallel light and is incident on a corresponding optical lens among the plurality of optical lenses (3100), the light is incident uniformly throughout, so that the beam pattern formed by the vehicle lamp (1) of the present invention can have uniform brightness throughout.

[0067] For example, the plurality of optical lenses (3100) may be positioned so that they move further forward in the front-back direction from top to bottom, similar to the plurality of light source modules (1100) described above, and at the same time, they may be positioned so that they move further to the left in the left-right direction.

[0068] FIGS. 8 and 9 are perspective views illustrating an optical lens according to an embodiment of the present invention, and FIG. 10 is a side view illustrating an optical lens according to an embodiment of the present invention. FIGS. 8 to 10 are examples illustrating one optical lens among a plurality of optical lenses (3100), and the remaining optical lenses can be applied similarly with only some differences in installation positions.

[0069] Referring to FIGS. 8 to 10, each of the plurality of optical lenses (3100) according to an embodiment of the present invention may include a light transmitting portion (3102) formed of a material that transmits light, such as glass, a plurality of incident lenses (3104) arranged on an incident surface (3102a) of the light transmitting portion (3102), and a plurality of exit lenses (3106) arranged on an exit surface (3102b) of the light transmitting portion (3102).

[0070] In an embodiment of the present invention, the plurality of incident lenses (3104) may have a semi-cylindrical shape formed to extend in one direction, which is to improve the spread characteristics of the beam pattern by allowing light to spread in the extension direction of the plurality of incident lenses (3104).

[0071] For example, when a low beam pattern is formed by a vehicle lamp (1) of the present invention, a plurality of incident lenses (3104) are formed to extend long in the left-right direction so that the length along which the low beam pattern is formed in the left-right direction becomes relatively long, thereby securing a wide field of vision in front of the vehicle.

[0072] When each of the plurality of incident lenses (3104) is formed to extend in one direction, light incident on each of the plurality of incident lenses (3104) can be emitted through two or more of the plurality of exit lenses (3106) that are positioned adjacent to each other in the extension direction of the plurality of incident lenses (3104). However, this is merely an example to help understanding of the present invention, and is not limited thereto. Depending on the light distribution characteristics of the beam pattern formed by the vehicle lamp (1) of the present invention, that is, the position, size, shape, brightness, etc. of the area to which light is irradiated, the plurality of incident lenses (3104) and the plurality of exit lenses (3106) may be formed one-to-one, one-to-many, many-to-one, many-to-many, or a combination thereof.

[0073] Meanwhile, each of the plurality of optical lenses (3100) may further include a plurality of shields (not shown) that block a portion of the light traveling to each of the plurality of exit lenses (3106), and the plurality of shields may be positioned between the plurality of entrance lenses (3104) and the plurality of exit lenses (3106) to block a portion of the light traveling to a corresponding exit lens among the plurality of exit lenses (3106).

[0074] A plurality of shields can serve to block light irradiated upward based on the cut-off line when a low beam pattern is formed by the vehicle lamp (1) of the present invention.

[0075] The plurality of shields may be positioned on either the incident surface (3102a) or the exit surface (3102b) of the light transmitting portion (3102), or may be positioned between the incident surface (3102a) and the exit surface (3102b) of the light transmitting portion (3102).

[0076] Some of the aforementioned plurality of optical lenses (3100) may be formed to have different lengths in the front-back direction from other parts, which is to allow some of the plurality of optical lenses (3100) to have different light distribution characteristics from other parts.

[0077] For example, when a low beam pattern is formed by a vehicle lamp (1) of the present invention, some of the plurality of optical lenses (3100) may form a high-intensity region having a relatively high brightness in the low beam pattern to ensure a sufficient viewing distance, and other parts may form a spread region having a relatively low brightness compared to the high-intensity region but allowing the high-intensity region to expand in at least one of the left-right direction and the up-down direction to improve the viewing range. Since the plurality of incident lenses (3104) and the plurality of exit lenses (3106) need to have different focal lengths depending on the light distribution characteristics of each of the high-intensity region and the spread region, it can be understood that some of the plurality of optical lenses (3100) have different lengths in the front-back direction from other parts.

[0078] At this time, it can be understood that the fact that different parts of the plurality of optical lenses (3100) have different lengths in the front-back direction means that the light transmitting portions (3102) of different parts of the plurality of optical lenses (3100) have different lengths.

[0079] Meanwhile, in an embodiment of the present invention, the incident surface (3102a) and the exit surface (3102b) of the light transmitting portion (3102) of each of the plurality of optical lenses (3100) can be tilted and positioned so that the plurality of optical lenses (3100) can be positioned forward from one side to the other in at least one direction so that the plurality of optical lenses (3100) can be positioned forward from one side to the other in at least one direction, and thus, corresponding incident lenses and exit lenses among the plurality of incident lenses (3104) and the plurality of exit lenses (3106) can be positioned to be staggered from each other in at least one direction, which is to ensure that the light emitted from the plurality of optical lenses (3100) faces forward even when the plurality of optical lenses (3100) are positioned by tilting at a predetermined angle rather than facing straight ahead.

[0080] For example, in the case where the incident surface (3102a) and the exit surface (3102b) of the light transmitting portion (3102) of each of the plurality of optical lenses (3100) are tilted so as to be positioned forward from the top to the bottom as shown in FIG. 11, the corresponding incident lenses and exit lenses among the plurality of incident lenses (3104) and the plurality of exit lenses (3106) can be positioned to be staggered in the vertical direction, and in this case, the corresponding incident lenses and exit lenses can be formed to be asymmetrical in the vertical direction with respect to the reference line (R) passing through the rear focus (F) of each of the plurality of exit lenses (3106) in the front-back direction.

[0081] That is, one of the corresponding entrance and exit lenses is formed so that the lower side is larger than the upper side with respect to the reference line (R), and the other is formed so that the upper side is larger than the lower side with respect to the reference line (R).

[0082] In this way, when a plurality of optical lenses (3100) are formed to be tilted, even when the plurality of optical lenses (3100) are positioned forward from one side to the other along the arrangement direction of the plurality of light source modules (1100), since the incident surface (3102a) and the exit surface (3102b) of each light transmitting portion (3102) of the plurality of optical lenses (3100) are positioned on the same plane as in FIGS. 1 to 5 described above, a single incident surface and an exit surface can be formed as a whole, so that an overall integrated and unified appearance can be implemented.

[0083] At this time, the rear focus (F) of each of the plurality of output lenses (3106) can have a shape of a point, line, plane, space, or a combination thereof depending on the area where light is actually focused.

[0084] Meanwhile, in an embodiment of the present invention, each of the plurality of optical lenses (3100) may have a step formed on a surface facing another adjacent optical lens in the arrangement direction of the plurality of light source modules (1100), and this step prevents light from being irradiated in an unnecessary direction and prevents a sense of disconnection from occurring between adjacent optical lenses among the plurality of optical lenses (3100), which will be described in detail later.

[0085] At this time, FIGS. 8 to 10 are examples of a case where a plurality of optical lenses (3100) are arranged in the vertical direction, and different optical lenses are positioned above and below one optical lens among the plurality of optical lenses (3100), so that a step portion is formed on each of the upper and lower surfaces, but the present invention is not limited thereto, and an optical lens positioned at the uppermost end among the plurality of optical lenses (3100) may have a step portion formed only on the lower surface, and conversely, an optical lens positioned at the lowest end among the plurality of optical lenses (3100) may have a step portion formed only on the upper surface.

[0086] The first optical section (2000) described above can be supported by the first support section (5000), and the second optical section (3000) can be supported by the second support section (6000).

[0087] Fig. 12 is a perspective view illustrating a first support according to an embodiment of the present invention.

[0088] Referring to FIG. 12, the first support member (5000) according to the embodiment of the present invention may include a plurality of mounting members (5100) for mounting each of the plurality of light path adjustment members (2100), and the plurality of mounting members (5100) may be positioned along the arrangement direction of the plurality of light path adjustment members (2100).

[0089] Each of the plurality of mounting portions (5100) may have a hollow space (5102) formed therein so that light generated from each of the plurality of light source modules (1100) may be incident on a corresponding one of the plurality of light path adjustment portions (2100), and each of the plurality of mounting portions (5100) may have a partition wall (5104) formed around the hollow space (5102) so as to have a shape corresponding to at least a portion of the edge of the corresponding one of the plurality of light path adjustment portions (2100), thereby enabling mounting of the corresponding one of the plurality of light path adjustment portions (2100).

[0090] Meanwhile, in an embodiment of the present invention, a step (S) may be formed between adjacent mounting portions so that the plurality of mounting portions (5100) are positioned forward from one side to the other along the arrangement direction of the plurality of light source modules (1100). This can be understood to be because, as described above, the plurality of light path adjustment portions (2100) are positioned forward from one side to the other along the arrangement direction of the plurality of light source modules (1100).

[0091] Fig. 13 is a perspective view illustrating a second support according to an embodiment of the present invention.

[0092] Referring to FIG. 13, the second support member (6000) according to an embodiment of the present invention may include a plurality of fixing frames (6100), a plurality of support frames (6200), and a plurality of connecting frames (6300).

[0093] The plurality of fixing frames (6100) can be positioned laterally spaced apart from each other so that both sides of each of the plurality of optical lenses (3100) are fixed, and in the embodiment of the present invention, since the plurality of optical lenses (3100) are positioned while tilting in at least one direction, the plurality of fixing frames (6100) can also be formed to be inclined at an angle corresponding to the tilting angle of the plurality of optical lenses (3100).

[0094] In an embodiment of the present invention, a plurality of optical lenses (3100) are arranged in a vertical direction, and each of the plurality of optical lenses (3100) is tilted so that the lower side is positioned forward compared to the upper side, so that the plurality of fixing frames (6100) can also be formed to be inclined so that they are positioned forward from the upper side to the lower side.

[0095] In addition, in the embodiment of the present invention, since a plurality of optical lenses (3100) are arranged in the vertical direction, a plurality of mounting frames (6100) can be positioned spaced apart from each other in the left-right direction, and each of the plurality of optical lenses (3100) can be mounted on a plurality of mounting frames (6100) in an area located on both sides in the left-right direction among the edge areas of the incident surface (3102a) of the light transmitting portion (3102).

[0096] A plurality of support frames (6200) can be positioned to be in contact with a plurality of mounting portions (5100), and a plurality of connecting frames (6300) can connect both ends of a plurality of support frames (6200) and both ends of a plurality of settling frames (6100) positioned spaced apart from each other in front of the plurality of support frames (6200), and can serve to connect the plurality of settling frames (6100) in the left-right direction so that the positions of the plurality of settling frames (6100) and the plurality of support frames (6200) are fixed so that there is no relative movement between them.

[0097] As described above, since the plurality of fixing frames (6100) are positioned spaced apart in the left-right direction and the plurality of support frames (6200) and the plurality of fixing frames (6100) are positioned spaced apart in the front-back direction, the light emitted from the plurality of light path adjusting units (2100) can travel sideways as well as to the plurality of optical lenses (3100) positioned in front of the plurality of light path adjusting units (2100), and among the light emitted from the plurality of light path adjusting units (2100), the light traveling sideways forms an image of a predetermined shape when the vehicle lamp (1) of the present invention is viewed from the side as well as the front, thereby improving the aesthetic appeal.

[0098] Meanwhile, among the plurality of optical lenses (3100), adjacent optical lenses may be positioned to be spaced apart from each other by a certain interval, and it can be understood that the manufacturing tolerance of each of the plurality of optical lenses (3100) takes into consideration assembly tolerances, etc.

[0099] That is, if adjacent optical lenses among the plurality of optical lenses (3100) are not positioned so as to be spaced apart from each other, structural interference may occur between the adjacent optical lenses due to manufacturing tolerances or assembly tolerances, etc., and there is also a possibility that they may collide with each other and be damaged due to vibrations generated during vehicle operation. Therefore, among the plurality of optical lenses (3100), adjacent optical lenses are positioned so as to be spaced apart from each other at a certain distance.

[0100] FIG. 14 is a side view illustrating a first optical lens and a second optical lens according to an embodiment of the present invention.

[0101] Referring to FIG. 14, the plurality of optical lenses (3100) may include a first optical lens (3110) and a second optical lens (3120) positioned adjacent to each other along the arrangement direction of the plurality of light source modules (1100). In the embodiment of the present invention, the first optical lens (3110) and the second optical lens (3120) are collectively referred to as two optical lenses positioned adjacent to each other along the arrangement direction of the plurality of light source modules (1100).

[0102] In addition, since the embodiment of the present invention is described as an example in which a plurality of light source modules (1100) are arranged in the vertical direction, the case in which the first optical lens (3110) and the second optical lens (3120) are also arranged in the vertical direction will be described as an example, and the case in which the second optical lens (3120) is located below the first optical lens (3110) will be described as an example.

[0103] The first optical lens (3110) and the second optical lens (3120) can be positioned to be spaced apart from each other by a certain distance (g) in the vertical direction in consideration of manufacturing tolerances, assembly tolerances, etc., and the first optical lens (3110) and the second optical lens (3120) being positioned to be spaced apart from each other can be understood to mean that the first facing surface (3111) of the first optical lens (3110) facing the second optical lens (3120) and the second facing surface (3121) of the second optical lens (3120) facing the first optical lens (3110) are positioned to be spaced apart from each other by a certain distance (g).

[0104] In the embodiment of the present invention, a case in which the gap (g) between the first optical lens (3110) and the second optical lens (3120) is 0.5 mm or more will be described as an example. This is because when the gap (g) is smaller than 0.5 mm, there is a high possibility that structural interference will occur between the first optical lens (3110) and the second optical lens (3120).

[0105] In the embodiment of the present invention, since the second optical lens (3120) is positioned below the first optical lens (3110), the first opposing surface (3111) can be understood as the lower surface of the first optical lens (3110), and the second opposing surface (3121) can be understood as the upper surface of the second optical lens (3120).

[0106] The first optical lens (3110) has front and rear ends of the first opposing surface (3111) that are positioned differently in the vertical direction, and in this case, the second opposing surface (3121) of the second optical lens (3120) may also have front and rear ends that are positioned differently in the vertical direction to correspond to the first opposing surface (3111).

[0107] In an embodiment of the present invention, the first opposing surface (3111) may be formed so that the rear end is positioned lower than the front end, and the gap (d1) between the front and rear ends of the first opposing surface (3111) is greater than the gap (g) between the first optical lens (3110) and the second optical lens (3120), and the second opposing surface (3121) may also be formed so that, similar to the first opposing surface (3111), the gap (d2) between the front and rear ends is greater than the gap (g) between the first optical lens (3110) and the second optical lens (3120).

[0108] At this time, in the embodiment of the present invention, a step portion (t1) having a step in the arrangement direction of the plurality of light source modules (1100) is formed between the front and rear ends of the first facing surface (3111), and similarly, a step portion (t2) is formed between the front and rear ends of the second facing surface (3121), so that the distance (d1, d2) between the front and rear ends of each of the first facing surface (3111) and the second facing surface (3121) has a distance greater than the distance (g) between the first optical lens (3110) and the second optical lens (3120).

[0109] The distance (d1, d2) between the front and rear ends of each of the first opposing surface (3111) and the second opposing surface (3121) is made to be greater than the distance (g) between the first optical lens (3110) and the second optical lens (3120), as shown in FIG. 15, to prevent light (L) traveling through the distance between the first optical lens (3110) and the second optical lens (3120) from being irradiated in an unnecessary direction, thereby preventing the occurrence of glare, etc.

[0110] In addition, the distance (d1, d2) between the front and rear ends of each of the first opposing surface (3111) and the second opposing surface (3121) is made to be greater than the distance (g) between the first optical lens (3110) and the second optical lens (3120) so that when the vehicle lamp (1) of the present invention is viewed from the front, as shown in FIG. 16, a sense of disconnection between the first optical lens (3110) and the second optical lens (3120) is prevented from occurring, thereby reducing the aesthetic appeal.

[0111] In other words, when the vehicle lamp (1) of the present invention is viewed from the outside, the gap between the first optical lens (3110) and the second optical lens (3120) has a different color or contrast than the first optical lens (3110) or the second optical lens (3120), so when the external viewpoint, that is, the direction in which the gap is formed, is similar to the direction in which the gap is formed, a sense of disconnection may occur between the first optical lens (3110) and the second optical lens (3120). On the other hand, in the embodiment of the present invention, the gap (d1, d2) between the front and rear ends of each of the first facing surface (3111) and the second facing surface (3121) is formed to have a gap greater than the gap (g) between the first optical lens (3110) and the second optical lens (3120), so even when the direction in which the outside viewpoint and the direction in which the gap is formed are similar, the first optical lens (3110) and the second optical lens (3120) The first opposing surface (3111) or the second opposing surface (3121) is visible through the gap between the lenses (3120), thereby preventing a sense of disconnection from occurring between the first optical lens (3110) and the second optical lens (3120).

[0112] In the above-described drawings 14 to 16, the case where the front end of each of the first facing surface (3111) and the second facing surface (3121) is positioned higher than the rear end is described as an example, but the present invention is not limited thereto, and can be similarly applied to the case where the front end of each of the first facing surface (3111) and the second facing surface (3121) is positioned lower than the rear end.

[0113] In addition, the aforementioned FIGS. 15 and 16 are examples in which the gap (d2) between the front and rear ends of the second facing surface (3121) is omitted, and the gap (d2) between the front and rear ends of the second facing surface (3121) can be understood to be the same as the gap (d1) between the front and rear ends of the first facing surface (3111), as in the aforementioned FIG. 14.

[0114] Meanwhile, in the above-described embodiment, a case is described as an example in which a step portion (t1, t2) is formed on each of the first facing surface (3111) and the second facing surface (3121), so that the first facing surface (3111) and the second facing surface (3121) maintain a certain distance (g) in the arrangement direction of the plurality of light source modules (1100), and the distance (d1, d2) between the front and rear ends of each of the first facing surface (3111) and the second facing surface (3121) is greater than the distance (g) between the first facing surface (3111) and the second facing surface (3121), but the present invention is not limited thereto, and the front and rear ends of each of the first facing surface (3111) and the second facing surface (3121) may be formed as surfaces that are continuously formed without steps, and the first facing surface (3111) and the second facing surface (3121) The gap (d1, d2) between the front and rear ends of each of the first facing surface (3111) and the second facing surface (3121) may be made to have a gap greater than the gap (g) between the first facing surface (3111) and the second facing surface (3121) due to the inclination angle between the front and rear ends of each of the facing surfaces (3121).

[0115] FIG. 17 is a side view illustrating a first optical lens and a second optical lens according to another embodiment of the present invention.

[0116] Referring to FIG. 17, the first optical lens (3110) and the second optical lens (3120) according to another embodiment of the present invention may be formed as an inclined surface with the rear end positioned lower than the front end so that the distance (d1) between the front and rear ends of the first opposing surface (3111) is greater than the distance (g) between the first opposing surface (3111) and the second opposing surface (3121), and similarly, the second opposing surface (3121) may be formed as an inclined surface with the rear end positioned lower than the front end so that the distance (d2) between the front and rear ends of the second opposing surface (3121) is greater than the distance (g) between the first opposing surface (3111) and the second opposing surface (3121).

[0117] At this time, the inclination angle of the first opposing surface (3111) and the second opposing surface (3121) in the aforementioned FIG. 17 may be an angle that prevents light from being irradiated in an unnecessary direction without causing a sense of disconnection between adjacent optical lenses among the plurality of optical lenses (3100) based on a viewpoint viewed from the front of the vehicle lamp (1) of the present invention.

[0118] Meanwhile, in the embodiment of the present invention, an example will be described in which the distance (d1) between the front and rear ends of the first facing surface (3111) and the distance (d2) between the front and rear ends of the second facing surface (3121) are equal to each other so that the first facing surface (3111) and the second facing surface (3121) have a constant distance (g) overall along the arrangement direction of the plurality of light source modules (1100), but the present invention is not limited thereto, and in the case where some of the first facing surface (3111) and the second facing surface (3121) have different distances from other parts, the distance (d1) between the front and rear ends of the first facing surface (3111) and the distance (d2) between the front and rear ends of the second facing surface (3121) may be different from each other at least in some cases.

[0119] In addition, in the aforementioned FIG. 17, the case where the front end of each of the first facing surface (3111) and the second facing surface (3121) is positioned higher than the rear end is described as an example, but this is not limited thereto, and a similar case can be applied to a case where the front end of each of the first facing surface (3111) and the second facing surface (3121) is positioned lower than the rear end.

[0120] Meanwhile, in the embodiment of the present invention, a case is described where a step portion (t1, t2) is formed to be interlocked with the first opposing surface (3111) and the second opposing surface (3121) and a case where the first opposing surface (3111) and the second opposing surface (3121) are formed to have the same inclination angle, but this is an example of a case where the first opposing surface (3111) and the second opposing surface (3121) have a constant gap (g) as a whole, and is not limited thereto. In a case where some of the gaps between the first opposing surface (3111) and the second opposing surface (3121) are different from other parts, a step portion may be formed in at least one of the first opposing surface (3111) and the second opposing surface (3121), and the gap between the front and rear ends of at least one of the first opposing surface (3111) and the second opposing surface (3121) may be formed at the first The gap between the opposing surface (3111) and the second opposing surface (3121) may be formed as an inclined surface having a gap greater than, for example, the smallest gap.

[0121] As described above, the vehicle lamp (1) of the present invention can implement a slim exterior design by means of a plurality of optical lenses (3100) arranged in at least one direction, while preventing light from being irradiated in an unnecessary direction through a space between adjacent optical lenses among the plurality of optical lenses (3100), and preventing a feeling of disconnection from occurring due to a space between adjacent optical lenses among the plurality of optical lenses (3100).

[0122] Those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering its technical spirit or essential characteristics. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
