[0009] Hereinafter, an embodiment of a vehicle lamp according to the present invention will be described with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same. In the following description, the front-rear, up-down, left-right directions are directions in a vehicle-mounted state in which the vehicle lamp is mounted on a vehicle, and indicate directions when the vehicle is viewed from the driver's seat in the traveling direction of the vehicle. Note that 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 are directions in a state in which the vehicle is mounted on a vehicle (vehicle-mounted state). For example, when mounted on the front of the vehicle, the front is the front direction (front side), and the rear is the rear direction (rear side).

[0010] 1 to 5 are diagrams showing an example of a vehicle lamp 100 according to this embodiment. Fig. 1 is an exploded perspective view showing an example of the vehicle lamp 100, Fig. 2 is a front view showing an example of the vehicle lamp 100, Fig. 3 is a cross-sectional view taken along line AA in Fig. 2, Fig. 4 is a cross-sectional view taken along line BB in Fig. 2, and Fig. 5 is a cross-sectional view taken along line CC in Fig. 2. A shade 61, which will be described later, is omitted in Fig. 4. As shown in Figs. 1 to 5, the vehicle lamp 100 includes a light source unit 10, a reflector 20, a light source side lens 30, a projection lens 40, and a support member 50.

[0011] The light source unit 10 has a first light source 11, a second light source 12, and substrates 13 and 14. The first light source 11 emits light (indicated by light source L1) for forming a low beam pattern P1 (see FIG. 6) in front of the vehicle, for example. The second light source 12 emits light (indicated by light ray L2) for forming a high beam pattern P2 (see FIG. 6) in front of the vehicle, for example. The high beam pattern P2 includes an ADB pattern in which the second light source 12 is individually turned on and irradiated.

[0012] The first light source 11 and the second light source 12 are each a semiconductor light source such as an LED. A plurality of first light sources 11 and a plurality of second light sources 12 are provided, and are arranged in a line in the left-right direction. For example, five first light sources 11 are arranged in the left-right direction. The number of first light sources 11 is not limited to five, and may be four or less or six or more.

[0013] The second light sources 12 are arranged at intervals narrower in the left-right direction than the first light sources 11. The second light sources 12 may be capable of controlling the lighting state independently of each other. In the present embodiment, for example, 12 second light sources 12 are arranged in the left-right direction, but the number of second light sources 12 is not limited to 12, and may be 11 or less or 14 or more.

[0014] The first light source 11 is disposed above the second light source 12. In other words, the second light source 12 is disposed below the first light source 11. In this manner, the first light source 11 and the second light source 12 are disposed separately above and below.

[0015] The first light source 11 is mounted on a mounting surface 13a of the substrate 13. The substrate 13 is supported on an upper surface portion 51 of a support member 50. The mounting surface 13a is planar and faces upward. The first light source 11 has its light-emitting surface 11a facing upward. The second light source 12 is mounted on a mounting surface 14a of the substrate 14. The substrate 13 is supported on a front surface portion 52 of the support member 50. The mounting surface 14a is planar and faces forward. The second light source 12 has its light-emitting surface 12a facing forward. In this embodiment, the first light source 11 and the second light source 12 are supported on different surfaces (the upper surface portion 51 and the front surface portion 52) of the support member 50.

[0016] The reflector 20 reflects light from the first light source 11 toward the projection lens 40. The reflector 20 has a reflecting surface 21. The reflecting surface 21 extends upward from the substrate 13 and has a shape that is curved upward so as to be convex toward the front. The reflecting surface 21 is configured with a free-form surface based on, for example, an ellipse or a paraboloid. The reflecting surface 21 is provided corresponding to the first light source 11. In this embodiment, the first light source 11 and the reflecting surface 21 are arranged in a one-to-one relationship.

[0017] The light source side lens 30 is disposed in front of the second light sources 12. The light source side lens 30 emits light from the second light sources 12 towards the projection lens 40. The light source side lens 30 has a shape that extends in the left-right direction. The light source side lens 30 has an incident surface 31 and an exit surface 32. The incident surface 31 receives light from each second light source 12. The exit surface 32 emits the light that has entered from the incident surface 31.

[0018] The projection lens 40 is disposed in front of the reflector 20 and the light source side lens 30. The projection lens 40 is held by a support member 50 via a lens holder 60. The projection lens 40 has an incident surface 41 and an exit surface 42. The incident surface 41 receives light from the first light source 11 and the second light source 12. The incident surface 41 has a first convex portion 41a and a second convex portion 41b. The first convex portion 41a receives light emitted from the first light source 11 via the reflector 20. The second convex portion 41b receives light emitted from the second light source 12 via the light source side lens 30.

[0019] The first convex portion 41a and the second convex portion 41b are curved and protrude rearward so as to have respective focal points. The first convex portion 41a is formed so as to have a larger curvature than the second convex portion 41b. The first convex portion 41a is disposed above the second convex portion 41b. The first convex portion 41a protrudes rearward more than the second convex portion 41b.

[0020] The exit surface 42 emits the light incident from the first convex portion 41a of the entrance surface 41 to the front of the vehicle, forming a low beam pattern. The exit surface 42 also emits the light incident from the second convex portion 41b of the entrance surface 41 to the front of the vehicle, forming a high beam pattern. The exit surface 42 is formed by one curved surface. The exit surface 42 is, for example, an aspheric surface.

[0021] A light shielding portion 53 is disposed between the first light source 11 and the second light source 12 and the projection lens 40 in the front-rear direction. The light shielding portion 53 is disposed between the reflector 20 and the light source side lens 30 in the up-down direction. The light shielding portion 53 shields light emitted from the first light source 11, reflected by the reflecting surface 21 of the reflector 20, and directed toward the second convex portion 41b. The light shielding portion 53 also shields light emitted from the second light source 12 and directed toward the first convex portion 41a. Specifically, the light shielding portion 53 shields direct light from the second light source 12 and light emitted from the second light source 12, emitted from the exit surface 32 of the light source side lens 30, and directed toward the first convex portion 41a. In this way, the light shielding portion 53 shields not only direct light from the second light source 12, but also light that has passed through the light source side lens 30. The light shielding portion 53 is, for example, flat, and disposed along a horizontal plane. The front end of the light blocking portion 53 is disposed forward of the shade 61 .

[0022] A shade 61 is disposed above the light blocking portion 53. The shade 61 is supported on the upper surface side of the support member 50 described later. The shade 61 has a cutoff forming portion 62. The cutoff forming portion 62 forms a cutoff line CL (see FIG. 6) in the low beam pattern P1 (see FIG. 6) by passing light reflected by the reflecting surface 21 of the reflector 20. The cutoff forming portion 62 has a first straight portion 62a, an inclined portion 62b, and a second straight portion 62c. The first straight portion 62a and the second straight portion 62c are portions for forming horizontal cutoff lines CLa and CLc (see FIG. 6) of the low beam pattern. The inclined portion 62b is a portion for forming an oblique cutoff line CLb (see FIG. 6) of the low beam pattern. The cutoff forming portion 62 is disposed at the focal point of the first convex portion 41a of the projection lens 40 or in a position near the focal point.

[0023] The support member 50 supports the substrates 13 and 14. The support member 50 has an upper surface portion 51 that supports the substrate 13 and a front surface portion 52 that supports the substrate 14. The upper surface portion 51 and the front surface portion 52 are, for example, planar. The support member 50 dissipates heat generated by the first light source 11 and the second light source 12. The support member 50 may be provided with a heat dissipation portion such as fins 54 on the rear, upper, or lower portion.

[0024] Next, the operation of the vehicle lamp 100 configured as described above will be described. By turning on the first light source 11 of the vehicle lamp 100, a light ray L1 is emitted upward from the light emitting surface 11a. As shown in FIG. 3, the light ray L1 is reflected forward by the reflecting surface 21 and reaches the projection lens 40. A part of the light ray L1 passes through the cutoff forming portion 62 of the shade 61 and reaches the first convex portion 41a of the entrance surface 41 of the projection lens 40. The light ray L1 that reaches the first convex portion 41a enters the projection lens 40 from the first convex portion 41a and is emitted from the exit surface 42 to the front of the vehicle.

[0025] Moreover, by turning on the second light source 12 of the vehicle lamp 100, a light ray L2 is emitted from the light-emitting surface 12a. As shown in FIG. 3, the light ray L2 reaches the light-source-side lens 30. The light ray L2 that reaches the light-source-side lens 30 is polarized by the light-source-side lens 30 so as to enter the projection lens 40, and is emitted forward. The light ray L2 emitted forward reaches the second convex portion 41b of the entrance surface 41 of the projection lens 40. The light ray L2 that reaches the second convex portion 41b enters the projection lens 40 from the second convex portion 41b, and is emitted from the exit surface 42 to the front of the vehicle.

[0026] Fig. 6 is a diagram showing an example of an irradiation pattern PF that is irradiated 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, the VV line indicates the vertical line of the screen, and the HH line indicates the horizontal lines on the left and right sides of the screen. In addition, here, the intersection of the vertical line and the horizontal line is assumed to be the reference position in the horizontal direction.

[0027] 6, a low beam pattern P1 is formed ahead of the vehicle by light beams L1 incident on the first convex portion 41a of the projection lens 40 and emitted from the exit surface 42. A cutoff line CL is formed by light beams L1 passing through the cutoff line forming portion 62. The cutoff line CL includes horizontal cutoff lines CLa, CLc and oblique cutoff lines CLb. A high beam pattern P2 is formed ahead of the vehicle by light beams L2 incident on the second convex portion 41b of the projection lens 40 and emitted from the exit surface 42.

[0028] In this way, in the vehicle lamp 100, the first convex portion 41a and the second convex portion 41b are provided on the entrance surface 41 of the projection lens 40 so as to have two focal points. On the other hand, the exit surface 42 is formed, for example, by one curved surface. Therefore, even if the entrance surface 41 side is configured to have multiple focal points, it is possible to prevent the deterioration of the appearance when the vehicle lamp 100 is viewed from the front. Note that the exit surface 42 is not limited to a configuration formed by one curved surface. The exit surface 42 may be composed of multiple curved surfaces. In this case, the exit surface 42 may be a single surface formed by multiple curved surfaces, or may be a curved surface in which multiple curved surfaces are smoothly connected.

[0029] As described above, the vehicle lamp 100 according to this embodiment includes the first light source 11 that emits light to form a low beam pattern P1 ahead of the vehicle, the second light source 12 that emits light to form a high beam pattern P2 ahead of the vehicle, a support member 50 having an upper surface portion 51 that supports the first light source 11, and a front surface portion 52 that is a surface different from the upper surface portion 51 and supports the second light source 12, and a projection lens 40 having an entrance surface 41 into which light from the first light source 11 and the second light source 12 is incident, and an exit surface 42 that emits the light from the entrance surface 41 to form an irradiation pattern PF ahead of the vehicle. The projection lens 40 has two convex portions that protrude rearward on the entrance surface 41, and light from the first light source 11 is incident on the first convex portion 41a, which is one of the convex portions, and light from the second light source 12 is incident on the other convex portion, the second convex portion 41b, and the exit surface 42 is formed by a single curved surface.

[0030] According to this configuration, the first convex portion 41a and the second convex portion 41b are provided on the incident surface 41 of the projection lens 40 so as to have two focal points. On the other hand, the exit surface 42 is formed of a single curved surface. Therefore, even if the incident surface 41 side is configured to have multiple focal points, it is possible to prevent the deterioration of the appearance when the vehicle lamp 100 is viewed from the front.

[0031] In the vehicular lamp 100 according to this embodiment, the first light source 11 is disposed above the second light source 12, and the first convex portion 41a is disposed above the second convex portion 41b.

[0032] According to this configuration, the first light source 11 for forming the low beam pattern P1 is disposed above the second light source 12 for forming the high beam pattern P2, so that the light of the first light source 11 can be incident on the upper side of the projection lens 40, and the light of the second light source 12 can be incident on the lower side. This allows the low beam pattern P1 and the high beam pattern P2 to be appropriately formed in the vertical direction.

[0033] In the vehicle lamp 100 according to this embodiment, the upper surface portion 51 faces upward, and the front surface portion 52 faces forward.

[0034] According to this configuration, by emitting light from the first light source 11 upward, it is possible to more reliably cause the light to enter the upper side of the incident surface 41 of the projection lens 40, and by emitting light from the second light source 12 forward, it is possible to efficiently cause the light to enter the projection lens 40.

[0035] The vehicle lamp 100 of this embodiment further includes a cutoff forming portion 62 that is disposed between the first light source 11 and the projection lens 40 and forms a cutoff line CL in the low beam pattern P1 by passing a portion of the light from the first light source 11.

[0036] According to this configuration, the cutoff line forming portion 62 can reliably form the cutoff line CL in the low beam pattern P1.

[0037] In the vehicle lamp 100 of this embodiment, a shading portion 53 that blocks light from the second light source 12 toward the first convex portion 41a is disposed between the first light source 11 and the projection lens 40, and a cutoff forming portion 62 is provided on a shade 61 supported on the upper surface side of the support member 50.

[0038] According to this configuration, the cutoff line forming portion 62 provided on the shade 61 can reliably form the cutoff line CL in the low beam pattern P1.

[0039] In the vehicle lamp 100 according to this embodiment, the first convex portion 41a is formed to have a larger curvature than the second convex portion 41b.

[0040] According to this configuration, the light incident from the first convex portion 41a can be diffused more efficiently than the light incident from the second convex portion 41b.

[0041] 7 to 12 are diagrams showing a vehicle lamp 200 according to another example of this embodiment. Fig. 7 is an exploded perspective view showing an example of the vehicle lamp 200, Fig. 8 is a front view showing an example of the vehicle lamp 200, Fig. 9 is a cross-sectional view taken along the line DD in Fig. 8, Fig. 10 is a cross-sectional view taken along the line EE in Fig. 8, and Fig. 11 is a cross-sectional view taken along the line FF in Fig. 8. In Fig. 4, a shade 61, which will be described later, is omitted. As shown in Figs. 1 to 5, the vehicle lamp 200 includes a light source unit 110, a reflector 120, a light source side lens 130, a projection lens 140, and a support member 150.

[0042] The light source unit 110 has a first light source 111, a second light source 112, and substrates 113 and 114. The first light source 111 and the second light source 112 have the same configuration as the first light source 11 and the second light source 12 of the above-mentioned vehicle lamp 200. The vehicle lamp 200 differs from the vehicle lamp 100 in that the number of first light sources 111 is two. The first light source 111 emits light (shown by light ray L3) for forming a low beam pattern in front of the vehicle, for example. The second light source 112 is similar to that of the above-mentioned vehicle lamp 100, so a description thereof will be omitted.

[0043] The reflector 120 reflects the light from the first light source 111 toward the projection lens 140. The reflector 120 has a reflecting surface 121. One of the two reflectors 120 (for example, the left reflector 120) is provided with a cutoff forming portion 122 at an end portion on the light source side. The light from the first light source 111 passes through the cutoff forming portion 122 to form a cutoff line CL (see FIG. 6) in the low beam pattern P1 (see FIG. 6). The cutoff forming portion 122 has a first straight portion 122a, an inclined portion 122b, and a second straight portion 122c. The first straight portion 122a and the second straight portion 122c are portions for forming horizontal cutoff lines CLa and CLc (see FIG. 6) of the low beam pattern. The inclined portion 122b is a portion for forming an oblique cutoff line CLb (see FIG. 6) of the low beam pattern. The cutoff forming portion 122 is disposed at the focal point of the first convex portion 141a of the projection lens 140 or in a position near the focal point.

[0044] The light source side lens 130 is disposed in front of the second light source 112. The light source side lens 130 has a shape extending in the left-right direction. The light source side lens 130 has an incident surface 131 and an exit surface 132. The light source side lens 130 has the same configuration as the light source side lens 30 of the vehicle lamp 100 described above.

[0045] The projection lens 140 is disposed in front of the reflector 120 and the light source side lens 130. The projection lens 140 is held by the support member 150 via the lens holder 160. The projection lens 140 has an incident surface 141 and an exit surface 142. The incident surface 141 receives light from the first light source 111 and the second light source 112. The incident surface 141 has first convex portions 141a, 141b and a second convex portion 141c. The first convex portions 141a, 141b are provided in a state of being divided into a plurality of portions on the left and right. The first convex portion 141a receives light emitted from the first light source 111 on the right side and passing through the reflector 120. The first convex portion 141a receives light passing through the cutoff forming portion 122. The first convex portion 141b receives light emitted from the first light source 111 on the left side and passing through the reflector 120. The light emitted from the second light source 112 and passing through the light source side lens 130 is incident on the second convex portion 141c.

[0046] The first convex portions 141a, 141b and the second convex portion 141c are curved and protrude rearward so as to have respective focal points. In the vehicle lamp 200, the projection lens 140 has three focal points. The first convex portion 141a is formed so as to have a larger curvature than the first convex portion 141b and the second convex portion 141c. The first convex portions 141a, 141b are disposed above the second convex portion 141c. The first convex portion 141a protrudes rearward more than the first convex portion 141b and the second convex portion 141c. A step portion 141d (see FIG. 9) is formed between the first convex portion 141a and the second convex portion 141c.

[0047] Next, the operation of the vehicle lamp 200 configured as described above will be described. When the first light source 111 of the vehicle lamp 200 is turned on, a light ray L3 is emitted upward from the light emitting surface 111a. The light ray L3 is reflected forward by the reflecting surface 121 and reaches the projection lens 140, as shown in Figs. 9 and 10.

[0048] A part of the light ray L1 emitted from the first light source 111 arranged on the left side reaches a first convex portion 141a of the entrance surface 141 of the projection lens 140 via a cutoff forming portion 122 arranged at the rear end of the reflecting surface 121. The light ray L3 that reaches the first convex portion 141a enters the projection lens 140 from the first convex portion 141a and is emitted from the exit surface 142 in a condensed state toward the front of the vehicle.

[0049] The light ray L4 emitted from the first light source 111 arranged on the right side is reflected by the reflecting surface 121 and reaches the first convex portion 141b of the entrance surface 141 of the projection lens 140. The light ray L4 that reaches the first convex portion 141b enters the projection lens 140 from the first convex portion 141b and is emitted in a diffused state to the front of the vehicle from the exit surface 142. In this way, the first convex portions 141a, 141b arranged on the left and right of the projection lens 140 can form a light collection pattern via the cutoff forming portion 122 and a diffuse pattern not via the cutoff forming portion 122 separately.

[0050] Moreover, the operation of the vehicle lamp 100 when the second light source 112 is turned on is the same as that of the vehicle lamp 100, and therefore a description thereof will be omitted.

[0051] In this manner, the vehicle lamp 200 is configured such that the first convex portions (first convex portions 141a, 141b) are provided on the upper side of the projection lens 140 so as to have focal points on the left and right sides, respectively. On the other hand, the emission surface 142 is formed of a single curved surface. Therefore, even if the vehicle lamp 200 is configured to have multiple focal points on the incidence surface 141 side, it is possible to prevent deterioration in appearance when viewed from the front.

[0052] The vehicle lamp 200 according to this embodiment has a reflecting surface 121 that reflects the light emitted from the first light source 111 toward the projection lens 140, and the cutoff forming portion 122 is provided at the rear end of the reflecting surface 121.

[0053] According to this configuration, since the cutoff forming portion 122 is provided at the rear end portion of the reflecting surface 121, the cutoff line CL can be formed in the low beam pattern P1 without providing a shade.

[0054] In the vehicular lamp 200 according to this embodiment, the first protrusions (141a, 141b) are provided in a state in which they are divided into a plurality of parts on the left and right.

[0055] According to this configuration, the shapes of the multiple first protrusions 141a and 141b can be adjusted individually. This allows the low beam pattern P1 to be adjusted more finely. In addition, since a shade for forming the cutoff line CL is not required, the number of parts can be reduced.

[0056] 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. [Explanation of symbols]
