Additionally, in each drawing of the invention, each component may be depicted slightly enlarged or reduced for convenience of explanation. Throughout the specification, the same reference numerals refer to the same components.

[0034] Hereinafter, the present invention will be described with reference to the drawings for explaining a vehicle lamp according to embodiments of the present invention.

[0035] FIGS. 1 and FIGS. 2 are perspective views showing a vehicle lamp according to an embodiment of the present invention, and FIG. 3 is a side view showing a vehicle lamp according to an embodiment of the present invention.

[0036] Referring to FIG. 1, a vehicle lamp (1) according to an embodiment of the present invention may include a light source unit (100), an optical unit (200), and a light transmission unit (300), and the light source unit (100), the optical unit (200), and the light transmission unit (300) may be accommodated in an internal space formed by a lamp housing (not shown) and a cover lens (not shown) coupled to the lamp housing to allow light to be irradiated to the outside of the vehicle.

[0037] In an embodiment of the present invention, the vehicle lamp (1) can be used for various functions, such as a lighting function that ensures the driver's visibility during night driving of the vehicle, such as a headlamp, a signaling function that informs drivers of surrounding vehicles or pedestrians of the vehicle's driving status, such as a position lamp, a daytime running lamp, a turn signal lamp, a brake lamp, and a function that forms a light distribution pattern consisting of characters, patterns, or a combination thereof that indicates various information that needs to be conveyed to drivers or pedestrians on the road surface around the vehicle, and the vehicle lamp (1) of the present invention may be used for a single function among the aforementioned functions, or may be used together for two or more functions.

[0038] Hereinafter, in the embodiments of the present invention, the vehicle lamp (1) of the present invention is described as an example of a case in which it is used to form a light distribution pattern including at least one pattern area on the road surface around the vehicle, but is not limited thereto, and can be similarly applied to a case in which the vehicle lamp (1) of the present invention forms a light distribution pattern for a lighting function or a signal function.

[0039] The light source unit (100) can generate light having a color or brightness suitable for the function of the vehicle lamp (1) of the present invention, and the light generated from the light source unit (100) can be directed to be incident on an optical unit (200) located in front of the light source unit (100).

[0040] At this time, the optical unit (200) being located in front of the light source unit (100) is the direction in which light is irradiated from the vehicle lamp (1) of the present invention, and the direction in which the front actually means may vary depending on the location or direction in which the vehicle lamp (1) of the present invention is installed.

[0041] In addition, when the vehicle lamp (1) of the present invention forms a light distribution pattern on the road surface around the vehicle, at least one of the light source unit (100), the optical unit (200), and the light transmission unit (300) may be arranged at an angle toward the road surface with respect to the horizontal direction. In an embodiment of the present invention, the case in which the light source unit (100), the optical unit (200), and the light transmission unit (300) are arranged at an angle (θ) toward the road surface with respect to the horizontal direction (S) will be described as an example.

[0042] The light source unit (100) may include a plurality of light sources (110, 120, 130), and in an embodiment of the present invention, the light source unit (100) includes a plurality of light sources (110, 120, 130) so as to form a light distribution pattern including a plurality of pattern areas corresponding to each of the plurality of light sources (110, 120, 130) by the vehicle lamp (1) of the present invention.

[0043] At this time, each of the plurality of pattern regions may have a character, a pattern, or a shape formed by a combination thereof, and as a result, the light distribution pattern including the plurality of pattern regions may also have a character, a pattern, or a shape formed by a combination thereof.

[0044] In an embodiment of the present invention, the case in which the light source unit (100) includes three light sources (110, 120, 130) is described as an example, but this is because the light distribution pattern formed by the vehicle lamp (1) of the present invention includes three pattern regions, and the number of light sources included in the light source unit (100) may vary depending on the number of pattern regions included in the light distribution pattern formed by the vehicle lamp (1) of the present invention.

[0045] The fact that the light distribution pattern includes a plurality of pattern regions can be understood as the light distribution pattern including a plurality of pattern regions formed to have the same size at the same distance from the vehicle, a plurality of pattern regions formed to have different sizes at the same distance from the vehicle, a plurality of pattern regions formed to have the same size at different distances from the vehicle, or a plurality of pattern regions formed to have different sizes at different distances from the vehicle.

[0046] In an embodiment of the present invention, the plurality of light sources (110, 120, 130) are described as examples where semiconductor light-emitting devices such as LEDs (Light Emitting Diodes) are used, but are not limited thereto. The plurality of light sources (110, 120, 130) may use various types of light sources such as LDs (Laser Diodes) or bulbs in addition to LEDs, and depending on the type of light source, optical elements such as lenses, mirrors, and reflectors may be additionally used.

[0047] Hereinafter, in embodiments of the present invention, a plurality of light sources (110, 120, 130) will be referred to as the first light source (110), the second light source (120), and the third light source (130).

[0048] The optical unit (200) can transmit light generated from each of the plurality of light sources (110, 120, 130) to form a pattern area corresponding to each of the plurality of light sources (110, 120, 130).

[0049] A plurality of light sources (110, 120, 130) may be turned on or off collectively or sequentially, and when a plurality of light sources (110, 120, 130) are turned on or off sequentially, an animation effect may be implemented due to the pattern area formed by each of the plurality of light sources (110, 120, 130).

[0050] FIGS. 4 and 5 are perspective views showing an optical part according to an embodiment of the present invention, FIGS. 6 and 7 are exploded perspective views showing an optical part according to an embodiment of the present invention, and FIG. 8 is a front view showing an optical part according to an embodiment of the present invention.

[0051] Referring to FIGS. 4 to 8, in an embodiment of the present invention, the optical unit (200) may include a plurality of incident lenses (210; 211, 212, 213), a plurality of exit lenses (220; 221, 222, 223), and a plurality of shields (230; 231, 232, 233).

[0052] The optical part (200) may be divided into a plurality of transmission areas (A1, A2, A3) that transmit light generated from each of a plurality of light sources (110, 120, 130), and in an embodiment of the present invention, the plurality of transmission areas (A1, A2, A3) are referred to as a first transmission area (A1) that transmits light from a first light source (110), a second transmission area (A2) that transmits light from a second light source (120), and a third transmission area (A3) that transmits light from a third light source (130).

[0053] At this time, the optical section (200) is divided into three transmission regions (A1, A2, A3) because the light source section (100) includes three light sources (110, 120, 130), and depending on the number of light sources included in the light source section (100), the optical section (200) may be composed of one transmission region or divided into two or more transmission regions.

[0054] Hereinafter, in an embodiment of the present invention, a pattern area formed by light passing through a first transmission area (A1) is referred to as the "first pattern area," a pattern area formed by light passing through a second transmission area (A2) is referred to as the "second pattern area," and a pattern area formed by light passing through a third transmission area (A3) is referred to as the "third pattern area."

[0055] A plurality of incident lenses (210) may be placed on the incident surface (241) of an optical member (240) made of a material through which light is transmitted, such as glass, and a plurality of exit lenses (220) may be placed on the exit surface (242) of the optical member (240), and light incident on each of the plurality of incident lenses (210) may pass through the optical member (240) and be incident on and exited by an exit lens among the plurality of exit lenses (220) that corresponds to each of the plurality of incident lenses (210).

[0056] At this time, a plurality of incident lenses (210) and a plurality of exit lenses (220) are used as micro lenses having a relatively short focal length so that the size of the optical part (200) can be reduced.

[0057] In the embodiment of the present invention, the case in which a plurality of incident lenses (210) and a plurality of exit lenses (220) correspond to each other in a one-to-one manner is described as an example, but is not limited thereto. Depending on the light distribution characteristics such as the shape, size, and position of the light distribution pattern formed by the vehicle lamp (1) of the present invention, the plurality of incident lenses (210) and a plurality of exit lenses (220) may correspond to each other in a one-to-one, one-to-many, many-to-one, many-to-many, etc.

[0058] A plurality of shields (230) may serve to block a portion of the light incident on each of the plurality of emission lenses (220), and each of the plurality of shields (230) may include an opening (230a) through which light is transmitted, and depending on the shape or size of the opening (230a), the shape or size of the pattern area may change due to the light emitted through each of the plurality of emission lenses (220).

[0059] In an embodiment of the present invention, a plurality of shields (230) are formed on the incident surface (241) of an optical member (240) by deposition or coating, etc., as an example, but are not limited thereto. A plurality of shields (230) may be formed on at least one of the incident surface (241) and the exit surface (242) of the optical member (240), or may be formed inside the optical member (240). When a plurality of shields (230) are formed inside the optical member (240), it can be understood that the optical member (240) is composed of two or more shields and a plurality of shields (230) are positioned between them.

[0060] The optical unit (200) may have different sizes for each of the plurality of transmission areas (A1, A2, A3) depending on the size of the pattern area formed by each of the plurality of transmission areas (A1, A2, A3) and the distance from the vehicle where the pattern area is formed.

[0061] For example, among the multiple transmission areas (A1, A2, A3), the first pattern area formed by the first transmission area (A1) is formed at the furthest distance from the vehicle, and the third pattern area formed by the third transmission area (A3) is formed at the closest distance from the vehicle. In this case, the first transmission area (A1) has the largest size and the third transmission area (A3) has the smallest size. This is because, in order for the pattern areas formed at different distances from the vehicle to have uniform brightness, the pattern area formed at a greater distance from the vehicle requires a higher amount of light.

[0062] At this time, the distance at which the first to third pattern areas are formed from the vehicle can be understood as the distance between the center of each of the first to third pattern areas and the vehicle in the direction at which the first to third pattern areas are formed from the vehicle lamp (1) of the present invention.

[0063] In addition, among the multiple transmission areas (A1, A2, A3), the size of the pattern area formed by the first transmission area (A1) is the largest and the size of the pattern area formed by the third transmission area (A3) is the smallest, so the first transmission area (A1) has the largest size and the third transmission area (A3) has the smallest size, because as the size of the pattern area increases, a high amount of light is required to have uniform brightness.

[0064] Meanwhile, if the first to third pattern areas formed by each of the first to third transmission areas (A1, A2, A3) have the same size at different distances from the vehicle, or if the first to third pattern areas have different sizes at the same distance from the vehicle, the size of the first to third transmission areas (A1, A2, A3) and the size of the output lens and shield belonging to each of the first to third transmission areas (A1, A2, A3) among the plurality of output lenses (220) may differ.

[0065] Hereinafter, in an embodiment of the present invention, among a plurality of emission lenses (220), an emission lens belonging to the first transmission area (A1) is referred to as the "first emission lens," an emission lens belonging to the second transmission area (A2) is referred to as the "second emission lens," and an emission lens belonging to the third transmission area (A3) is referred to as the "third emission lens."

[0066] Additionally, among the plurality of shields (230), the shield belonging to the first penetration area (A1) is referred to as the "first shield," the shield belonging to the second penetration area (A2) is referred to as the "second shield," and the shield belonging to the third penetration area (A3) is referred to as the "third shield."

[0067] FIG. 9 is a schematic diagram showing an emission lens having different diameters depending on the size of the transmission area according to an embodiment of the present invention.

[0068] Referring to FIG. 9, among the first to third transmission regions (A1, A2, A3), the first pattern region formed by light passing through the first transmission region (A1) has the largest size because it is formed at the farthest distance from the vehicle, and the third pattern region formed by light passing through the third transmission region (A3) has the smallest size because it is formed at the closest distance from the vehicle.

[0069] At this time, the first exit lens (221) belonging to the first transmission area (A1) may have the smallest diameter (d1), and the third exit lens (223) belonging to the third transmission area (A3) may have the largest diameter (d3), because the opening sizes of the shields belonging to the first to third transmission areas (A1, A2, A3) among the plurality of shields (230) are different from each other.

[0070] FIG. 10 is a schematic diagram showing a shield having openings of different sizes depending on the size of the transmission area according to an embodiment of the present invention.

[0071] Referring to FIG. 10, among the plurality of shields (230), the opening (231a) of the first shield (231) belonging to the first transmission area (A1) may be formed to have the smallest size, and the opening (233a) of the third shield (233) belonging to the third transmission area (A3) may be formed to have the largest size, so that the first emission lens (221) has the smallest diameter and the third emission lens (223) has the largest diameter.

[0072] This is because when multiple shields (230) all have openings (230a) of the same size, the further the light is irradiated from the vehicle, the more the light diffuses and a relatively larger pattern area is formed. Therefore, the opening size of the shield is formed smaller as the light is irradiated from the vehicle, so that even pattern areas formed at different distances from the vehicle can have the same size.

[0073] In the aforementioned FIGS. 9 and 10, an example is described in which the first to third pattern areas are formed with the same size at different distances from the vehicle, such that the transmission area corresponding to the pattern area formed at a greater distance from the vehicle among the plurality of transmission areas (A1, A2, A3) has a larger size, while the openings of the emission lens and shield have a smaller size. However, this is not limited thereto, and in the case where the first to third pattern areas are formed with different sizes at the same distance from the vehicle, the transmission area corresponding to the pattern area having a larger size among the plurality of transmission areas (A1, A2, A3) has a larger size, while the openings of the emission lens and shield have a larger size, so that the first to third pattern areas are formed with different sizes at the same distance from the vehicle.

[0074] Consequently, when the first to third pattern areas have the same size but are formed at different distances from the vehicle, the sizes of the first to third transmission areas (A1, A2, A3) are different from each other, and at the same time the diameters (d1, d2, d3) of the first to third emission lenses (221, 222, 223) are different from each other, as shown in FIG. 11, when light (L1, L2, L3) generated from each of the first to third light sources (110, 120, 130) is irradiated onto the road surface around the vehicle to form the first to third pattern areas (P1, P2, P3), the first to third pattern areas (P1, P2, P3) can have the same size and brightness even if they are formed at different distances (g1, g2, g3) from the vehicle.

[0075] At this time, FIG. 11 is an example in which the first pattern area (P1) is formed at the farthest distance from the vehicle, the third pattern area (P3) is formed at the closest distance from the vehicle, and the first to third pattern areas (P1, P2, P3) have the same size.

[0076] Meanwhile, as shown in FIG. 12, when the first to third pattern areas (P1, P2, P3) have different sizes but are formed at the same distance (g) from the vehicle, the first to third pattern areas (P1, P2, P3) have uniform brightness, so that the first transmission area (A1) corresponding to the first pattern area (P1) having the largest size among the plurality of transmission areas (A1, A2, A3) has the largest size, and the opening (231a) of the first emission lens (221) and the first shield (231) has the largest size, and the third transmission area (A3) corresponding to the third pattern area (P3) having the smallest size has the smallest size, and the opening (233a) of the third emission lens (223) and the third shield (233) can have the smallest size.

[0077] In the above-described embodiment, examples are provided for cases where the first to third pattern areas formed at different distances from the vehicle have the same size and brightness, and cases where the first to third pattern areas formed at the same distance from the vehicle have different sizes. However, this is merely an example to aid in understanding the present invention and is not limited thereto. Depending on the size of each of the first to third pattern areas (P1, P2, P3) or the distance at which each of the first to third pattern areas (P1, P2, P3) is formed, the size of each of the first to third transmission areas (A1, A2, A3), the diameter of each of the plurality of emission lenses (220), and the size of each of the openings (230a) of the plurality of shields (230) may vary.

[0078] Meanwhile, FIGS. 11 and 12 described above are examples of cases where the first to third light sources (110, 120, 130) are simultaneously lit to form the first to third pattern areas (P1, P2, P3) simultaneously, but are not limited thereto. When the first to third light sources (110, 120, 130) are lit sequentially, the first to third pattern areas (P1, P2, P3) are formed sequentially as in FIG. 13, thereby enabling an animation effect. This animation effect may be used for design purposes to express the unique characteristics of the vehicle, or for purposes such as turn signal lamps or backup lamps to more clearly recognize the driving direction of the vehicle, but is not limited thereto. It may be used for various purposes where information provision is required through the sequential lighting of the first to third light sources (110, 120, 130).

[0079] The light transmission unit (300) can serve to collect light generated from each of the plurality of light sources (110, 120, 130) and transmit it to the optical unit (200).

[0080] FIG. 14 is a perspective view showing a light transmission unit according to an embodiment of the present invention, and FIG. 15 is a front view showing a light transmission unit according to an embodiment of the present invention.

[0081] Referring to FIGS. 14 and 15, the light transmission unit (300) may include a plurality of light guide units (310, 320, 330) that guide light generated from each of the plurality of light sources (110, 120, 130) to be transmitted to the optical unit (200).

[0082] In an embodiment of the present invention, a plurality of light guide sections (310, 320, 330) can serve to convert light generated from each of a plurality of light sources (110, 120, 130) into parallel light and transmit it to an optical section (200), thereby ensuring that light generated from each of a plurality of light sources (110, 120, 130) is uniformly transmitted to each of a plurality of transmission areas (A1, A2, A3), and as a result, the pattern area formed by the light transmitting through each of the plurality of transmission areas (A1, A2, A3) has uniform brightness.

[0083] In the embodiment of the present invention, a case in which a lens with a forward convex shape is used to enable light collection is described as an example, but this is merely an example to help understand the present invention and is not limited thereto, and various optical elements capable of collecting light, such as reflectors or mirrors, can be used instead of lenses for the plurality of light guide parts (310, 320, 330).

[0084] Each of the incident surfaces of the plurality of light guide sections (310, 320, 330) is formed integrally, and the exit surfaces (311, 321, 331) are formed separately, enabling easy assembly of the light transmission section (300).

[0085] Multiple light guide sections (310, 320, 330) may have different sizes, because multiple transmission areas (A1, A2, A3) have different sizes.

[0086] For example, among the plurality of light guide parts (310, 320, 330), the first light guide part (310) that guides light incident on the first transmission area (A1) has the largest size, and the third light guide part (330) that guides light incident on the third transmission area (A3) has the smallest size.

[0087] The vehicle lamp (1) of the present invention described above enables the sharing of some components for forming a plurality of pattern areas when a light distribution pattern including a plurality of pattern areas is formed on the road surface around the vehicle, thereby reducing the number of parts for forming a plurality of pattern areas, and consequently, the configuration and cost can be reduced.

[0088] A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included within the scope of the present invention.
