[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0041] Referring to FIGS. 1 to 11, a vehicle lamp 10 according to an embodiment of the present disclosure includes a first light source unit 100, a second light source unit 200, a first total reflection lens 300, a second total reflection lens 400, and an emission lens 500.

[0042] For reference, in FIGS. 1 to 8, D11 represents a front side, and D12 represents a rear side. D21 represents an in-board direction of a vehicle toward one end, and D22 represents an out-board direction of the vehicle toward the other end. D31 is an upward direction, and D32 is a downward direction. However, an up-down direction and a left-right direction may be directions based on the illustrated drawings, and the up-down direction and the left-right direction may be changed according to an environment in which the vehicle lamp 10 is installed.

[0043] The first light source unit 100 includes a plurality of first light source parts 110 and is disposed at one side based on the left-right direction. Further, the second light source unit 200 includes a plurality of second light source parts 210 and is disposed on the other side of the first light source unit 100.

[0044] In detail, the plurality of first light source parts 110 may be arranged in the left-right direction. Further, the plurality of second light source parts 210 may be arranged in the left-right direction. An element or device capable of emitting light may be used for the first light source part 110 and the second light source part 210. For example, the first light source part 110 and the second light source part 210 may be provided as light emitting diodes (hereinafter, referred to as LEDs). Further, the first light source part 110 and the second light source part 210 may be mounted on a board part (not illustrated) such as a printed circuit board.

[0045] The first total reflection lens 300 includes a first lens structure 300 provided to condense light radiated from the plurality of first light source parts 110 and emit the light to the front. The first lens structure 300 may be provided to receive light incident from the plurality of first light source parts 110 by internal total reflection and emit the light toward the emission lens 500.

[0046] A plurality of second lens structures 400a, 400b, and 400c that condense light radiated from the plurality of second light source parts 210 and emit the light to the front are integrally formed in the second total reflection lens 400. Further, the second total reflection lens 400 is integrally formed on the other side of the first total reflection lens 300.

[0047] Further, the emission lens 500 includes a first emission lens part 510 disposed in front of the first total reflection lens 300 and a second emission lens part 520 disposed in front of the second total reflection lens 400.

[0048] Here, a first light distribution pattern is formed by light emitted from the first emission lens part 510 (see FIG. 9). Further, a second light distribution pattern different from the first light distribution pattern is formed by light emitted from the second emission lens part 520 (see FIG. 10). Further, the first light distribution pattern and the second light distribution pattern may overlap each other to form a high beam pattern of a head lamp (see FIG. 11).

[0049] In the specification, the fact that characteristics of the light distribution patterns are different from each other means that light distribution characteristics and projected pattern images of the first light distribution pattern and the second light distribution pattern are different from each other. This may be implemented by a difference between characteristics and shapes of the first total reflection lens 300 and the second total reflection lens 400 and the first emission lens part 510 and the second emission lens part 520.

[0050] For example, the first light distribution pattern may be a light distribution pattern (Wide Zone) for securing a field of view in a front peripheral area and securing visibility during turning. Further, the second light distribution pattern may be a long-range light distribution pattern (Hot Zone) for securing a view of a front central area. The first light distribution pattern and the second light distribution pattern may overlap each other to form the high beam pattern.

[0051] In detail, the first total reflection lens 300 and the second total reflection lens 400 may be formed integrally and formed as a single body. The first total reflection lens 300 is obtained by integrally forming a member for guiding light incident from the plurality of first light source parts 110.

[0052] The second lens structures 400a, 400b, and 400c may serve to condense light radiated from the second light source part 210 and guide the light to the front. The light radiated to the front may be emitted to the front through the emission lens 500 to form the second light distribution pattern having the high beam pattern.

[0053] In this way, a member for guiding and condensing light for forming a plurality of light distribution patterns may be formed as a single body, thereby implementing component simplification. Further, therefore, assembly may be simplified, assembly tolerances may be minimized, and light efficiency may be improved.

[0054] The emission lens 500 includes the first emission lens part 510 disposed in front of the first total reflection lens 300 and the second emission lens part 520 disposed in front of the second total reflection lens 400.

[0055] The first emission lens part 510 may include a first incident surface 511 on which light output from the first total reflection lens 300 is incident and a first emission surface 512 from which the incident light is output.

[0056] In detail, the first incident surface 511 may be formed as a spherical surface formed convexly in a direction toward the first total reflection lens 300. Further, the first emission surface 512 may be formed as a spherical surface formed convexly toward the front. For example, the first incident surface 511 and the first emission surface 512 may be formed symmetrically in the left-right direction with respect to an optical axis of the first emission lens part 510.

[0057] The second emission lens part 520 may include a second incident surface 521 on which light output from the second total reflection lens 400 is incident and a second emission surface 522 from which the incident light is output. Further, the first incident surface 511 and the second incident surface 521 may be formed in different shapes.

[0058] In detail, the second incident surface 521 may be bent to be closer to the second total reflection lens 400 as it goes from one end to the other end based on the left-right direction. Accordingly, the second incident surface 521 and the second emission lens part 520 may be formed asymmetrically in the left-right direction based on an optical axis of the second emission lens part 520.

[0059] Here, the second emission lens part 520 may be formed to extend in the left-right direction to cover all of the plurality of second lens structures 400a, 400b, and 400c. In this way, the first incident surface 511 and the second incident surface 521 may be formed in different shapes.

[0060] Further, the first emission surface 512 may be formed in a convex shape to the front. Further, the first emission surface 512 may be symmetrical with respect to the optical axis of the first emission lens part 510.

[0061] Further, the second emission surface 522 may be bent to be closer to the second total reflection lens 400 as it goes from one end to the other end based on the left-right direction. Accordingly, the second emission surface 522 may be formed asymmetrically in the left-right direction with respect to the optical axis of the second emission lens part 520.

[0062] Here, the first emission surface 512 and the second emission surface 522 may be formed in different shapes but may be continuously formed without a stepped portion in the left-right direction. The first emission surface 512 and the second emission surface 522 disposed in the front and forming an exterior of the vehicle lamp 10 are continuously formed, and thus the vehicle lamp 10 according to the present disclosure may provide an advantageous design effect by minimizing a disconnection sense between the light distribution patterns having different characteristics.

[0063] Meanwhile, the first light distribution pattern may be formed by the light emitted from the first emission lens part 510 (see FIG. 9). Further, the second light distribution pattern having characteristics different from those the first light distribution pattern may be formed by the light emitted from the second emission lens part 520 (see FIG. 10). Further, the first light distribution pattern and the second light distribution pattern may overlap each other to form the high beam pattern (see FIG. 11.

[0064] In the specification, the fact that characteristics of the light distribution patterns are different from each other means that light distribution characteristics and projected pattern images of the first light distribution pattern and the second light distribution pattern are different from each other. This may be implemented by a difference between characteristics and shapes of the first total reflection lens 300 and the second total reflection lens 400 and the first emission lens part 510 and the second emission lens part 520.

[0065] The first lens structure 300 may include a (1-1).sup.th light incident portion 310a and (1-2).sup.th light incident portions 310b and 310c, through which light is incident, and a first body portion 320.

[0066] The (1-2).sup.th light incident portions 310b and 310c may be arranged on both sides of the (1-1).sup.th light incident portion 310a in the left-right direction. In detail, the two (1-2).sup.th light incident portions 310b and 310c may be formed and may be formed symmetrically with respect to the (1-1).sup.th light incident portion 310a.

[0067] The first body portion 320 may be integrally formed in front of the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c. In detail, the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c may be integrally formed on a rear surface of the first body portion 320.

[0068] In detail, the first lens structure 300 may be a total internal reflection (TIR) lens that guides and condenses light incident by total internal reflection. The (1-1).sup.th light incident portion 310a may include a central light incident surface 311 and a side light incident surface 312 on which light is incident and a total reflection surface 313 by which the incident light is totally reflected. Optical characteristics of the first lens structure 300 may be determined by a shape of the (1-1).sup.th light incident portion 310a formed according to a focal length of the first lens structure 300, a focal length of the second emission lens part 520, a depth of the central light incident surface 311, a size (diameter) of the central light incident surface 311, and an inclination angle of the side light incident surface 312. The (1-2).sup.th light incident portions 310b and 310c may have a structure similar to that of the (1-1).sup.th light incident portion 310a.

[0069] The first body portion 320 forms a body of the first lens structure 300, and the light incident on the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c may undergo internal total reflection in the first body portion 320.

[0070] Meanwhile, the first body portion 320 may include an integrated light output surface 321 that emits light incident from the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c to the front.

[0071] The integrated light output surface 321 may be formed in a curved surface, and a cross-sectional shape of the integrated light output surface 321 in the left-right direction may be formed in a concavely curved shape in a direction toward the first light source unit 100.

[0072] In detail, the first total reflection lens 300 may include the one first lens structure 300, and the first lens structure 300 may include the one integrated light output surface 321. In the embodiment of the present disclosure, the first lens structure 300 may include a plurality of light incident portions (the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c), and the light incident on the plurality of light incident portions may be emitted through the one integrated light output surface 321. The integrated light output surface 321 may be continuously formed without a stepped portion.

[0073] Further, central axes C2 of the (1-2).sup.th light incident portions 310b and 310c may be formed at an angle different from that of a central axis C1 of the (1-1).sup.th light incident portion 310a. Further, the central axes C2 of the plurality of (1-2).sup.th light incident portions 310b and 310c may be formed symmetrically to each other with respect to the central axis C1 of the (1-1).sup.th light incident portion 310a.

[0074] In detail, referring to the embodiment illustrated in FIG. 3, the light incident on the (1-1).sup.th light incident portion 310a may form one focal point FH and may be emitted through the first emission lens part 510 to form a central area of the first light distribution pattern.

[0075] Meanwhile, referring to the embodiment illustrated in FIG. 4, the (1-2).sup.th light incident portions 310b and 310c may be formed to radiate light in a direction toward the central axis C1 of the (1-1).sup.th light incident portion 310a. Further, the central axes C2 of the (1-2).sup.th light incident portions 310b and 310c may form a predetermined angle 1 with respect to the central axis C1 of the (1-1).sup.th light incident portion 310a. The light incident on the (1-2).sup.th light incident portions 310b and 310c and then emitted through the first emission lens part 510 may be provided to form a peripheral area of the first light distribution pattern due to the shape of the (1-2).sup.th light incident portions 310b and 310c.

[0076] Accordingly, the light incident on the (1-1).sup.th light incident portion 310a and traveling may improve a luminous intensity of the first light distribution pattern, and the light incident on the (1-2).sup.th light incident portions 310b and 310c may be spread in a horizontal direction to satisfy light distribution requirements of the first light distribution pattern.

[0077] Further, referring to FIGS. 3 and 4, a path of the light incident from the (1-1).sup.th light incident portion 310a may be provided to form a horizontal focal point FH on the integrated light output surface 321.

[0078] Further, an optical path by a portion of the light incident from the (1-2).sup.th light incident portions 310b and 310c may be provided to form the same horizontal focal point FH as the horizontal focal point of the (1-1).sup.th light incident portion 310a on the integrated light output surface 321.

[0079] Further, an optical path by the other portion of the light incident from the (1-2).sup.th light incident portions 310b and 310c may be provided to be defocused on the integrated light output surface 321.

[0080] In detail, the light incident from the (1-2).sup.th light incident portions 310b and 310c and guided does not travel to be focused on one focal point, but may be provided (defocused) such that the portion of the light forms the focal point and the other portion of the light does not form the focal point on the integrated light output surface 321. Accordingly, the light incident from the (1-2).sup.th light incident portions 310b and 310c and guided is emitted through the first emission lens part 510 and is spread in the horizontal direction, thereby forming a light distribution of the first light distribution pattern having the high beam pattern.

[0081] Accordingly, turning visibility of the first light distribution pattern may be secured, and light distribution performance may be satisfied.

[0082] Meanwhile, referring to FIG. 5, the first body portion 320 may include a first lower surface 325 and a first upper surface 323 provided above the first lower surface 325. Further, the first upper surface 323 may be formed to be inclined downward as it goes to the integrated light output surface 321.

[0083] For example, the first lower surface 325 of the first body portion 320 may extend in a direction parallel to an optical axis, and the first upper surface 323 of the first body portion 320 may be formed to be inclined downward toward the front. Accordingly, the light incident through the (1-1).sup.th light incident portion 310a and the (1-2).sup.th light incident portions 310b and 310c may move more to a lower area than to an upper area with respect to the optical axis due to total reflection inside the first body portion 320, and as a result, more light may be emitted upward when emitted through the first emission lens part 510.

[0084] Accordingly, a light distribution of the high beam pattern of the head lamp for securing upward visibility may be secured, and light distribution performance may be improved.

[0085] Meanwhile, referring to the embodiment illustrated in FIGS. 6 to 8, the plurality of second lens structures 400a, 400b, and 400c may include second light incident portions 410a, 410b, and 410c and second body portions 420a, 420b, and 420c arranged in front of the second light incident portions 410a, 410b, and 410c, respectively. Individual light output surfaces 421a, 421b, and 421c through which light is emitted to the front may be formed in the second body portions 420a, 420b, and 420c, respectively.

[0086] Further, the plurality of individual light output surfaces 421a, 421b, and 421c respectively provided in the plurality of second lens structures 400a, 400b, and 400c may be formed on different planes.

[0087] In detail, the second lens structures 400a, 400b, and 400c may be a TIR lens that guides and condenses light incident by total internal reflection. A structure of the second light incident portions 410a, 410b, and 410c may be similar to that of the first light incident portion but may differ from the first light incident portion in terms of the depth of the central light incident surface, the size (diameter) of the central light incident surface, and the inclination angle of the side light incident surface.

[0088] Unlike the first total reflection lens 300, the second total reflection lens 400 may have a shape in which the plurality of second lens structures 400a, 400b, and 400c are integrally formed. Optical paths of the light guided by the plurality of second lens structures 400a, 400b, and 400c may be different from each other. Further, the plurality of second lens structures 400a, 400b, and 400c may include the second light incident portions 410a, 410b, and 410c and the second body portions 420a, 420b, and 420c, respectively, but shapes of the plurality of second light incident portions 410a, 410b, and 410c may be formed differently, and shapes of the plurality of second body portions 420a, 420b, and 420c may be formed differently. This may correspond to a shape (e.g., a shape formed to be bent) of the second emission lens part 520.

[0089] The light incident on the plurality of second light incident portions 410a, 410b, and 410c may be emitted to the front through the individual light output surfaces 421a, 421b, and 421c corresponding to the second light incident portions 410a, 410b, and 410c, respectively.

[0090] For example, as in the embodiment illustrated in FIGS. 1 to 8, an incident surface and an emission surface of the second emission lens part 520 may be formed to be bent as they go toward the other side. Further, the plurality of individual light output surfaces 421a, 421b, and 421c may be formed at different positions to correspond to the bent direction of the second emission lens part 520. For example, as the individual light output surface is located closer to the other side, the individual light output surface is disposed closer to the second light source unit 200.

[0091] Further, the light guided by the plurality of second lens structures 400a, 400b, and 400c may form a plurality of vertical focal points FV1, FV2, and FV3 based on a vertical direction, respectively. Further, the plurality of vertical focal points FV1, FV2, and FV3 may be formed on the individual light output surfaces 421a, 421b, and 421c and bent in bent directions of the individual light output surfaces 421a, 421b, and 421c.

[0092] In detail, the second emission surface 522 and the second incident surface 521 may be formed to be bent, and thus the vertical focal points FV1, FV2, and FV3 at portions of the second emission lens part 520 may be different from each other. Thus, the vertical focal points of the second lens structures 400a, 400b, and 400c may be formed at different positions to correspond to different focal points at the portions of the second emission lens part 520.

[0093] Further, the vertical focal points of the second lens structures 400a, 400b, and 400c may be formed on the individual light output surfaces 421a, 421b, and 421c, and the plurality of individual light output surfaces 421a, 421b, and 421c may be formed at different positions, like the vertical focal points.

[0094] Accordingly, even when the second emission lens part 520 is formed to be bent to correspond to a shape of the vehicle, the second light distribution pattern that satisfies light distribution and light distribution performance may be formed.

[0095] Meanwhile, the second body portions 420a, 420b, and 420c may include second lower surfaces and second upper surfaces provided above the second lower surfaces. Further, the second upper surfaces may be inclined downward as they go toward the individual light output surfaces 421a, 421b, and 421c.

[0096] For example, the second lower surfaces of the second body portions 420a, 420b, and 420c may extend in a direction parallel to the optical axis, and the second upper surfaces of the second body portions 420a, 420b, and 420c may be inclined downward as they go toward the front. Accordingly, the light incident through the second light incident portions 410a, 410b, and 410c may move more to a lower area than to an upper area with respect to the optical axis due to total reflection inside the second body portions 420a, 420b, and 420c, and as a result, more light may be emitted upward when emitted through the second emission lens part 520.

[0097] Accordingly, a light distribution of the high beam pattern of the head lamp for securing upward visibility may be secured, and light distribution performance may be improved.

[0098] According to the embodiment of the present disclosure, a member for guiding and condensing light for forming a plurality of light distribution patterns may be formed as a single body, thereby implementing component simplification. Further, according to the embodiment of the present disclosure, assembly may be simplified, assembly tolerance may be minimized, and thus light efficiency may be improved.
