[0016] Hereinafter, embodiments of a vehicle headlamp according to the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially identical. In the following description, the front-rear, up-down, and left-right directions refer to directions when the vehicle headlamp is mounted on a vehicle and viewed from the driver's seat in the direction of vehicle travel. In this embodiment, the up-down direction is parallel to the vertical direction, and the left-right direction is horizontal. In this embodiment, the front and rear directions refer to directions when the vehicle headlamp is mounted on a vehicle (mounted on a vehicle). For example, when mounted on the front of a vehicle, the front is the front direction (front side), and the rear is the rear direction (rear side).

[0017] 1 to 3 are diagrams illustrating an example of a vehicle headlamp 100 according to the present embodiment. FIG. 1 is an exploded perspective view illustrating the example of the vehicle headlamp 100, FIG. 2 is a front view illustrating the example of the vehicle headlamp 100, and FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2. Note that FIGS. 2 and 3 omit illustration of some components, such as a holding unit 50 and a lens holder 60, which will be described later. Also, in FIG. 2, the second lens 40 is indicated by a dashed dotted line, and is illustrated so that the configuration of the rear side of the second lens 40 can be seen. As shown in FIGS. 1 to 3, the vehicle headlamp 100 includes a light source unit 10, a reflector 20, a first lens 30, a second lens 40, and a holding unit 50.

[0018] The light source unit 10 has a first light source (low beam light source) 11, a second light source (light source) 12, and a substrate 13. The first light source 11 emits a first light (low beam light) L1 for forming a low beam pattern in front of the vehicle, for example. The second light source 12 emits a second light (light) L2 for forming a high beam pattern in front of the vehicle, for example.

[0019] The first light source 11 and the second light source 12 are semiconductor light sources such as LEDs. A plurality of first light sources 11 and a plurality of second light sources 12 are provided, and are arranged side by side in the left-right direction. One first light source 11 is arranged in the center in the left-right direction, and one on each side in the left-right direction, for a total of three first light sources 11. The number of first light sources 11 is not limited to three, and may be two or less or four or more.

[0020] A plurality of second light sources 12 are arranged at narrower intervals in the left-right direction than the first light sources 11. For example, the lighting state of each of the second light sources 12 may be controllable independently. In this embodiment, for example, two second light sources 12 are arranged, but the number is not limited to this and may be one or three or more. The first light source 11 is arranged below the second light source 12. In other words, the second light source 12 is arranged above the first light source 11. In this way, the first light source 11 and the second light source 12 are arranged one above the other.

[0021] The first light source 11 and the second light source 12 are mounted on a mounting surface 13a of the substrate 13. In this embodiment, the first light source 11 and the second light source 12 are mounted on one substrate 13. This eliminates the need to form a separate substrate for each light source, allowing for a reduction in the number of components. The mounting surface 13a is planar. The substrate 13 is placed on a substrate support surface 51 (see FIG. 1) of the holder 50, which will be described later. The substrate 13 is placed along the substrate support surface 51. The substrate 13 is placed with the mounting surface 13a perpendicular or nearly perpendicular to a horizontal plane, for example. Note that the substrate 13 may also be placed with the mounting surface 13a facing diagonally upward or diagonally downward toward the front.

[0022] The reflector 20 reflects the first light L1 from the first light source 11 toward the second lens 40. As shown in Fig. 1, the reflector 20 has a first member (component) 26 and a second member 27 that are fixed and integrally provided. The first member 26 and the second member 27 of the reflector 20 that are integrated are fixed to a holder 50.

[0023] The first reflecting surface 21 is provided on the first member 26 and disposed in front of the first light source 11. The first reflecting surface 21 reflects the first light L1 upward. The first reflecting surface 21 extends forward from the substrate 13 and has a shape that is curved upward so as to be convex forward. The first reflecting surface 21 is formed of a free-form surface based on, for example, an ellipse or a paraboloid. As shown in FIG. 2 , the first reflecting surfaces 21 are provided corresponding to the positions of the respective first light sources 11. In this embodiment, one first reflecting surface 21 is disposed in the center in the left-right direction, and one each on the left and right in the left-right direction. Note that the first reflecting surfaces 21 are not limited to being provided corresponding to the positions of the respective first light sources 11.

[0024] The second reflecting surface 22 is provided on the second member 27 and is disposed above the second light source 12. The second reflecting surface 22 reflects the first light L1 arriving from the first light source 11 via the first reflecting surface 21 forward. The second reflecting surface 22 has, for example, a curved shape that is convex upward. The second reflecting surface 22 is formed of, for example, a free-form surface based on an ellipse, a paraboloid, or a plane. The curvature of the second reflecting surface 22 may be the same as or different from the curvature of the first reflecting surface 21.

[0025] The second reflecting surface 22 forms an edge portion 24 at its lower end. As shown in FIG. 2, the edge portion 24 has a first linear portion 24a, an inclined portion 24b, and a second linear portion 24c. The first linear portion 24a and the second linear portion 24c are portions for forming horizontal cutoff lines CLa and CLc (see FIG. 6) of the low beam pattern. The inclined portion 24b is a portion for forming an oblique cutoff line CLb (see FIG. 6) of the low beam pattern. The edge portion 24 is located at a focal point F of a second lens 40 (described later) or in the vicinity of the focal point F.

[0026] The second reflecting surface 22 has an edge 24, which is its lower end, positioned lower than the upper end of the direct-ray portion 31 and the internal reflecting portion 32 of the first lens 30, which will be described later. In other words, when viewed from the front, the second reflecting surface 22 is positioned so that its lower end overlaps with the first lens 30. By positioning the second reflecting surface 22 and the first lens 30 in this manner, it is possible to form a low beam pattern and a high beam pattern in front of the vehicle so that they are not separated in the vertical direction.

[0027] Fig. 4 is an enlarged view of the main parts in Fig. 3. Fig. 5 is a cross-sectional view taken along the line BB in Fig. 2. Figs. 4 and 5 show the configuration of the first lens 30 and its vicinity. As shown in Figs. 4 and 5, the first lens 30 is disposed in front of the second light source 12. The first lens 30 is held by the first member 26 that constitutes the reflector 20, and is provided integrally with the first member 26. With this configuration, the first lens 30 is held by the first member 26, and the positional relationship between the first lens 30 and the first reflecting surface 21 is defined without any additional alignment or the like.

[0028] The first lens 30 has a direct-irradiation portion 31 and an internally reflective portion 32. The direct-irradiation portion 31 is disposed on the optical axis AX of the second lens 40, which will be described later. The direct-irradiation portion 31 has a lower portion 31b, which is the portion below the optical axis AX, that is larger in the vertical dimension than an upper portion 31a, which is the portion above the optical axis AX. This configuration allows the first lens 30 and the second reflective surface 22 to be disposed close to each other without interfering with each other.

[0029] The direct light portion 31 has an incident surface 33 and an exit surface 34. A portion of the light from the second light source 12 is incident on the incident surface 33. As shown in FIG. 4, the incident surface 33 is curved in a vertical cross section such that a central portion 33a thereof protrudes toward the second light source 12. As shown in FIG. 5, the incident surface 33 is disposed so as to face two light source units 10 in a horizontal cross section. With this configuration, one incident surface 33 is disposed so as to face two light source units 10, and light from the two light source units 10 is incident on one incident surface 33. In a horizontal cross section, the incident surface 33 is formed, for example, linearly along the left-right direction.

[0030] As shown in FIG. 4 , the exit surface 34 is curved in a vertical cross section such that a central portion 34c in the vertical direction protrudes forward. The curvature of the exit surface 34 is greater in the upper portion 34a, which is positioned above the optical axis AX, than in the lower portion 34b, which is positioned below the optical axis AX. In this configuration, the second light L2 emitted from the upper portion 34a is emitted in a direction more inclined toward the optical axis AX than the second light L2 emitted from the lower portion 34b. This prevents the second light L2 emitted from the upper portion 34a from being blocked by the second reflecting surface 22. Furthermore, as shown in FIG. 5 , the exit surface 34 has a horizontally central portion 34d that is linearly oriented along the horizontal direction in a horizontal cross section. This configuration allows light incident on the entrance surface 33 to be emitted while suppressing horizontal control. In addition, in a cross-sectional view, both left and right end portions 34e of the exit surface 34 are curved backward. With this configuration, light that reaches both left and right end portions 34e of the exit surface 34 can be emitted so as to be refracted toward the optical axis AX.

[0031] The internal reflecting portions 32 are disposed laterally in the axial direction of the optical axis AX with respect to the direct-irradiation portion 31. As shown in FIG. 5 , in this embodiment, the internal reflecting portions 32 are disposed, for example, on both sides in the left-right direction with respect to the direct-irradiation portion 31. Each internal reflecting portion 32 has a symmetrical shape. Each internal reflecting portion 32 has an incident surface 35, a reflecting surface 36, and an exit surface 37.

[0032] A portion of the light from the light source unit 10 is incident on the incident surface 35. Light emitted from the light source unit 10 and directed laterally in the left and right directions relative to the incident surface 33 of the direct radiation unit 31 is incident on the incident surface 35. The incident surface 35 is formed continuous with the incident surface 33 of the direct radiation unit 31. In other words, the incident surface 35 is formed in a state that curves backward from the incident surface 33 of the direct radiation unit 31 toward both the left and right directions. With this configuration, the light incident on the incident surface 35 can be diffused toward the reflecting surface 36.

[0033] The reflecting surface 36 is disposed on the outer side in the left-right direction (opposite the optical axis AX) of the incident surface 35. In a cross-sectional view, the reflecting surface 36 has a shape that extends forward toward the outer side in the left-right direction. The reflecting surface 36 has, for example, a curved shape, but is not limited to this. The reflecting surface 36 internally reflects light incident from the incident surface 35 toward the front.

[0034] The exit surface 37 is disposed outward in the left-right direction from the exit surface 34 of the direct radiation portion 31 and in front of the reflecting surface 36. The exit surface 37 emits forward the light that has been internally reflected by the reflecting surface 36. With this configuration, even light that does not reach the incident surface 33 of the direct radiation portion 31 and heads laterally in the left-right direction can be emitted forward as light that constitutes a high beam pattern.

[0035] The second lens 40 is disposed in front of the reflector 20. The second lens 40 is held by the holding unit 50 via the lens holder 60. The second lens 40 has an incident surface 41 and an exit surface 42. The incident surface 41 receives the first light L1 from the reflector 20 and the second light L2 emitted from the first lens 30. The exit surface 42 emits the first light L1 incident from the incident surface 41 toward the front of the vehicle to form a low beam pattern. The exit surface 42 also emits the second light L2 incident from the incident surface 41 toward the front of the vehicle to form a high beam pattern. The second lens 40 may be provided with a light diffusion unit (not shown) on at least one of the incident surface 41 and the exit surface 42. This light diffusion unit diffuses the light incident on the incident surface 41 and the light emitted from the exit surface 42 in the left-right or up-down direction.

[0036] The holder 50 has a substrate support surface 51 at its front that supports the substrate 13. The substrate support surface 51 is, for example, flat and is disposed facing forward. The holder 50 dissipates heat generated by the first light source 11 and the second light source 12. The holder 50 may be provided with a heat dissipation section (not shown), such as a fin, at its rear, top, or bottom.

[0037] Next, the operation of the vehicle headlamp 100 configured as described above will be described. When the first light source 11 of the vehicle headlamp 100 is turned on, a first light L1 is emitted from the light-emitting surface 11a. As shown in FIG. 3, the first light L1 is reflected upward by the first reflecting surface 21, reflected forward by the second reflecting surface 22, and reaches the second lens 40. The first light L1 that has reached the second lens 40 is irradiated by the second lens 40 toward the front of the vehicle.

[0038] Fig. 6 is a diagram showing an example of a light distribution pattern PF projected onto a virtual screen in front of a vehicle, and shows a pattern corresponding to a vehicle that drives on the left side of the road. In Fig. 6, lines VV indicate vertical lines on the screen, and lines HH indicate horizontal lines on the left and right sides of the screen. In addition, here, the intersection of the vertical and horizontal lines is assumed to be the reference position in the horizontal direction.

[0039] 6, a low beam pattern P1 is formed ahead of the vehicle by the first light L1 emitted from the second lens 40. A cutoff line CL is formed by the light of the first light L1 that passes through the edge portion 24. The cutoff line CL includes horizontal cutoff lines CLa and CLc and an oblique cutoff line CLb.

[0040] Furthermore, by turning on the second light source 12 of the vehicle headlamp 100, second light L2 is emitted from the light-emitting surface 12a. As shown in FIGS. 4 and 5, a portion of the second light L2 emitted forward (hereinafter referred to as second light L2a) reaches the direct-irradiation portion 31 of the first lens 30. The light L2a enters the first lens 30 from the incident surface 33 of the direct-irradiation portion 31 and is emitted forward from the exit surface 34 without being internally reflected, reaching the second lens 40. As shown in FIG. 4, the curvature of the upper portion 34a of the exit surface 34 is greater than the curvature of the lower portion 34b. Therefore, the second light L2a emitted from the upper portion 34a is emitted in a direction more inclined toward the optical axis AX than the second light L2a emitted from the lower portion 34b. This prevents the second light L2a emitted from the upper portion 34a from being blocked by the second reflecting surface 22. The second light L2a that reaches the second lens 40 is irradiated by the second lens 40 toward the front of the vehicle, and forms a part of the high beam pattern P2 (pattern P2a) as shown in FIG.

[0041] 5, another portion of the second light L2 emitted forward (hereinafter referred to as second light L2b) reaches the internal reflecting portion 32 of the first lens 30. The light L2b enters the first lens 30 from the incident surface 35 of the internal reflecting portion 32, is internally reflected by the reflecting surface 36, and is emitted forward from the exit surface 37 to reach the second lens 40. The second light L2b that has reached the second lens 40 is irradiated forward by the second lens 40, and forms part of the high beam pattern P2 (pattern P2b) as shown in FIG. 6. In this way, the second light L2b emitted from the light source 12 in directions spreading in the left-right direction is internally reflected forward by the internal reflecting portion 32 of the first lens 30, thereby contributing to the formation of the high beam pattern P2 as pattern P2b.

[0042] As described above, the vehicle headlamp 100 of this embodiment comprises a second light source 12 that emits light to form a high beam pattern P2 ahead of the vehicle, a first lens 30 that is arranged in front of the second light source 12 and emits light forward, and a second lens 40 that is arranged in front of the first lens 30 and emits light emitted from the first lens 30 ahead of the vehicle, and the first lens 30 has a direct portion 31 that is arranged on the optical axis AX of the second lens 40 and that receives and emits forward a portion of the light from the second light source 12, and an internal reflection portion 32 that is arranged axially to the side of the direct portion 31 on the optical axis AX and internally reflects and emits forward a portion of the light from the second light source 12.

[0043] According to this configuration, the internal reflection portion 32 is disposed laterally in the axial direction of the optical axis AX relative to the direct radiation portion 31, so that light from the second light source 12 directed laterally from the direct radiation portion 31 can be internally reflected by the internal reflection portion 32 and emitted forward. The second light L2 from the second light source 12 that deviates laterally from the direct radiation portion 31 can also be emitted forward and used as a high beam pattern, making it possible to efficiently use the light from the light source.

[0044] In the vehicle headlamp 100 according to this embodiment, a plurality of second light sources 12 are provided, and the direct light portion 31 has a single incident surface 33 that faces the plurality of second light sources 12 and onto which light from the plurality of second light sources 12 is incident. With this configuration, light from the plurality of second light sources 12 can be made incident onto the single incident surface 33, and therefore, in a configuration in which a plurality of second light sources 12 are provided, the number of parts of the first lens 30 can be reduced.

[0045] In the vehicle headlamp 100 according to this embodiment, the second light sources 12 are arranged side by side in the horizontal direction when mounted on the vehicle. With this configuration, the second light sources 12 are arranged side by side in the horizontal direction, so that the illumination area of ​​the high beam pattern P2 can be secured in the horizontal direction.

[0046] In the vehicle headlamp 100 according to this embodiment, the internal reflection portions 32 are disposed on both sides in the horizontal direction of the direct-irradiation portion 31. With this configuration, light that deviates from the second light source 12 to the sides in the horizontal direction of the direct-irradiation portion 31 can be used as a high beam pattern.

[0047] The vehicle headlamp 100 according to this embodiment further includes a first light source 11 that is disposed below the second light source 12 and on the same plane as the second light source 12, and that emits a first light L1 for forming a low beam pattern P1 ahead of the vehicle; a first reflecting surface 21 that is disposed in front of the first light source 11 and that reflects the first light L1 upward; and a second reflecting surface 22 that is disposed above the second light source 12 and that reflects the first light L1 that arrives from the first light source 11 via the first reflecting surface 21 forward. The second lens 40 irradiates the first light L1 reflected by the second reflecting surface 22 ahead of the vehicle. With this configuration, the first light source 11 and the second light source 12 are disposed on the same plane, allowing the first light source 11 and the second light source 12 to be mounted on a single substrate 13. This eliminates the need for separate substrates for each light source, thereby reducing the number of components.

[0048] In the vehicle headlamp 100 according to this embodiment, the direct-illumination portion 31 has an exit surface 34 that curves from its upper end to its lower end so as to protrude forward, and the lower end of the second reflecting surface 22 is located below the upper end of the direct-illumination portion 31. The curvature of the exit surface 34 of the direct-illumination portion 31 in a portion 34a above the optical axis AX is greater than the curvature of the portion 34b below the optical axis AX. With this configuration, the second light L2 emitted from the upper portion 34a is emitted in a direction more inclined toward the optical axis AX than the second light L2 emitted from the lower portion 34b. This makes it possible to prevent the second light L2 emitted from the upper portion 34a from being blocked by the second reflecting surface 22.

[0049] In the vehicle headlamp 100 according to this embodiment, the vertical dimension of the lower portion 31b below the optical axis AX of the direct-illumination portion 31 is larger than the vertical dimension of the upper portion 31a above the optical axis AX. This configuration allows the first lens 30 and the second reflecting surface 22 to be disposed close to each other without interfering with each other.

[0050] In the vehicle headlamp 100 according to this embodiment, the first lens 30 is provided integrally with the first member 26 that constitutes the first reflecting surface 21. According to this configuration, the first lens 30 is held by the first member 26, and thus the positional relationship between the first lens 30 and the first reflecting surface 21 is defined without the need for additional alignment or the like.

[0051] The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the vehicle headlamp 100 is configured to be able to form two patterns, a low beam pattern P1 and a high beam pattern P2, but is not limited to this. The vehicle headlamp 100 may be configured not to form the low beam pattern P1, for example. In this case, the first light source 11 and the reflector 20 may not be provided.

[0052] In the above embodiment, the first lens 30 has been described with the internal reflection portions 32 disposed on both horizontal sides of the direct irradiation portion 31 as an example, but the present invention is not limited to this. The internal reflection portions 32 may be disposed in other directions, such as on the side in the vertical direction or diagonally, as long as they are disposed on the side of the direct irradiation portion 31 in the axial direction of the optical axis AX. Furthermore, the internal reflection portions 32 may be disposed on one side of the direct irradiation portion 31 in the axial direction of the optical axis AX, rather than on both sides.
