[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-149702 [Patent Document 2] JP 2000-340014 A [Patent Document 3] International Publication No. 2022 / 130595 Summary of the Invention [Problem to be solved by the invention]

[0004] From the viewpoint of improving visibility, it is desirable to expand the illumination range of high beams. In particular, for saddle-type vehicles such as motorcycles that lean left and right when turning, it is desirable to expand the illumination range of high beams so that the road ahead can be better illuminated when the vehicle leans. However, if the illumination range is expanded to the left and right by adjusting the shape of the high beam reflector, although the illumination range is expanded, it becomes necessary to increase the output of the high beam light source to ensure the amount of light, and the heat dissipation structure also becomes necessary to be enlarged. If the illumination range were to be expanded by adding a light source or a reflector, the vehicle lamp would tend to become larger and its appearance would tend to change. Therefore, if a light source or a reflector is added to a conventional two-lens type vehicle lamp, the vehicle lamp would become larger than a three-lens type, making it difficult to achieve the same smart appearance as the conventional two-lens type. The present invention has been made in consideration of the above-mentioned circumstances, and has an object to expand the illumination range of a high beam while suppressing changes in the size and appearance of a vehicle lamp. [Means for solving the problem]

[0005] The present invention provides a vehicle lamp having a low beam light source, a high beam light source, and a light distribution member that distributes light from each light source, wherein the screen light distribution of the high beam light source includes a first region of a high beam main light distribution and a second region of an upper side light distribution toward left and right upper sides of the high beam main light distribution, the high beam light source constituting a light source of the high beam main light distribution and including a pair of left and right first high beam light sources provided at least one on each side of the center of the vehicle, and one or more second high beam light sources constituting a light source for the upper side light distribution, the vehicle lamp having an opaque lamp cover that covers at least either the left or right center of the lamp or the left or right central periphery, the second high beam light source being behind the lamp cover and overlapping with the lamp cover when viewed from the front of the vehicle. Effect of the Invention

[0006] It is possible to expand the high beam illumination range while minimizing changes to the size and appearance of the vehicle lamp. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description, directions such as front, rear, left, right, up and down are the same as directions relative to the vehicle unless otherwise specified. In addition, the symbol FR in each drawing indicates the front of the vehicle, the symbol UP indicates the upper side of the vehicle, and the symbol LH indicates the left side of the vehicle.

[0009] [First embodiment] FIG. 1 is a front view showing a light unit 10 for a saddle-ride type vehicle according to a first embodiment of the present invention together with the surrounding configuration. The light unit 10 constitutes one of the vehicle lamps and lighting devices of the saddle-ride type vehicle, and has a pair of left and right first light units 11 that constitute left and right headlights based on the vehicle center LC. Since the light unit 10 is disposed at the front of the vehicle, it can also be called a front light unit and a headlight unit (also called a headlamp). The vehicle center LC indicates the vehicle width center of the saddle-ride type vehicle.

[0010] 1, the periphery of the left and right first light units 11 is covered by a front cover 20 that constitutes a part of the vehicle body cover. The front cover 20 integrally includes an opaque lamp cover 21 that covers the area α between the left and right first light units 11 from the front, and left and right transparent covers 22 that transmit light from the left and right first light units 11. In this embodiment, the area α covered by the lamp cover 21 is a region in the left-right center of the light unit 10. However, this is not limited to this region, and the lamp cover 21 may be a covering member that covers at least one of the left-right center and the left-right periphery of the center of the front cover 20.

[0011] In this configuration, as shown in FIG. 1, the first light units 11 spaced apart on the left and right are exposed to the exterior, and the periphery of the first light units 11 is covered with a front cover 20 including a light body cover 21, resulting in the appearance of a so-called twin-lens type motorcycle. The light body cover 21 and the transparent cover 22 are not limited to being integral with the front cover 20, and may be separate covers from the front cover 20. The shape of the front cover 20 including the light body cover 21 may be changed as appropriate. The light body cover 21 and the transparent cover 22 may be combined as separate bodies rather than being integral.

[0012] Fig. 2 is a diagram showing the screen light distribution of the light unit 10 when the vehicle is upright, and shows a schematic range of a predetermined luminous intensity or more. The horizontal line H indicated by the line HH in Fig. 2 is a horizontal reference line parallel to the vehicle center plane, and the vertical line V indicated by the line VV is a reference line perpendicular to the vehicle center plane. The screen light distribution of the light unit 10 has a low beam light distribution area DL indicating the low beam area, a high beam main light distribution area DH1 indicating the area of ​​the high beam main light distribution, and left and right upper side light distribution areas DH2 indicating the areas of lateral upper light distribution extending upward on both the left and right sides of the high beam main light distribution area DH1.

[0013] The low beam light distribution area DL is an area that extends below the horizontal line H in the left and right directions (corresponding to the outside in the vehicle width direction) of the vertical line V when the vehicle is upright. Therefore, a low beam that can illuminate the road surface ahead while suppressing glare to oncoming vehicles and preceding vehicular traffic is obtained. FIG. 2 shows an example of the low beam light distribution area DL in schematic form, and it may be appropriately adjusted within an appropriate range for a low beam. For example, the low beam light distribution area DL does not have to be symmetrical. The low beam is also called a passing beam or a passing headlamp.

[0014] The high beam main light distribution area DH1 can also be said to be a basic light distribution area of ​​the high beam. The high beam main light distribution area DH1 is set to an area including at least an area above the horizontal line H and extending in the left and right directions (corresponding to the outside in the vehicle width direction) of the vertical line V when the vehicle is upright. In FIG. 2, for ease of explanation, the area above the horizontal line H is set as the high beam main light distribution area DH1, but the high beam main light distribution area DH1 may include an area below the horizontal line H, for example, may include an area overlapping with the low beam light distribution area DL. FIG. 2 shows an example of the high beam main light distribution area DH1 in a schematic manner, and may be changed as appropriate as long as it is within an appropriate range for a high beam. The high beam is also called a driving beam or a driving headlamp.

[0015] The left and right upper side light distribution areas DH2 are areas extending upward on both left and right sides of the high beam main light distribution area DH1 when the vehicle is upright, and correspond to areas of the high beam other than the basic light distribution. The left and right upper side light distribution areas DH2 are areas spaced apart on the left and right sides with respect to the vehicle center LC, and correspond to the range above the horizontal line H when the vehicle is upright. This makes it possible to expand the illumination range of the high beam by the amount of the left and right upper side light distribution areas DH2 compared to the case where only light corresponding to the high beam main light distribution area DH1 is radiated.

[0016] The saddle-type vehicle of this configuration is a vehicle that leans to the inside of a curve when traveling around a curve, that is, a motorcycle that leans left and right when turning. Since the saddle-type vehicle leans to the inside when traveling around a curve, the light corresponding to the upper side light distribution area DH2 can illuminate the area ahead of the curve. This provides a high beam that can improve forward visibility even when turning with the vehicle leaning.

[0017] More specifically, the light of the upper side light distribution area DH2, which is located relatively on the outside when the vehicle is tilted, can more easily illuminate the curve ahead or the shoulder on the outside of the curve, which are farther away, than the light of the high beam main light distribution area DH1. Also, depending on the tilt angle (also called bank angle) of the saddle-ride type vehicle and the curvature angle of the curve, the light of the upper side light distribution area DH2 on the other left or right side, which is located relatively on the inside when the vehicle is tilted, can more easily illuminate the curve ahead or the shoulder on the inside of the curve than the light of the high beam main light distribution area DH1. In this way, the light corresponding to the upper side light distribution area DH2 can improve the visibility of the curve ahead. Note that FIG. 2 shows the upper side light distribution region DH2 in a schematic manner, and the shape, size, position, and the like of the upper side light distribution region DH2 may be finely adjusted within the range in which forward visibility is improved.

[0018] In this description, a curve includes any road surface that bends left or right, including, for example, corners that exist on a circuit. The destination of a curve can also be referred to as the destination of a turn and the destination when the vehicle tilts. In this invention, "illuminating the destination of a curve" and "illuminating the destination when the vehicle tilts" mean illuminating at least one of the road surface ahead, the surroundings of that road surface, and the front of that road surface. In addition, even when the vehicle is not tilted, for example when traveling straight, the left and right sides in front can be illuminated with light corresponding to the upper side light distribution area DH2, improving visibility to the left and right of the front, and thus improving visibility ahead can be expected.

[0019] FIG. 3 is a diagram showing a state where the front cover 20 is removed from FIG. 3, the light unit 10 includes left and right first light units 11 and a second light unit 12 disposed between the left and right first light units 11. These units 11, 12 are supported by a support member 13 provided on the saddle-ride type vehicle. The front cover 20 is detachable from the support member 13.

[0020] The left and right first light units 11 are formed in a symmetrical structure with respect to the vehicle center LC, and integrally have a low beam irradiation section 31 located on the outer side in the vehicle width direction, and a first high beam irradiation section 32 located on the inner side in the vehicle width direction. The left and right first light units 11 do not have to have a symmetrical structure.

[0021] The low beam irradiation unit 31 includes a low beam light source 31a and a low beam reflector 31b that reflects the light from the low beam light source 31a to produce a low beam. The low beam light source 31a is a known light source such as an LED, and is disposed above the low beam reflector 31b, emitting visible light downward toward the low beam reflector 31b. The low beam reflector 31b is formed as a reflector that mirror-reflects the light from the low beam light source 31a toward the front of the vehicle. The low beam reflector 31b functions as a light distribution member that distributes the light from the low beam light source 31a to the low beam light distribution area DL shown in FIG.

[0022] The first high beam irradiator 32 includes a first high beam light source 32a and a first high beam reflector 32b that reflects light from the first high beam light source 32a toward a high beam main light distribution area DH1 shown in FIG. The first high beam light source 32a is a known light source such as an LED, is disposed above the first high beam reflector 32b, and emits visible light downward toward the first high beam reflector 32b. The first high beam reflector 32b is formed as a reflecting mirror that mirror-reflects the light from the first high beam light source 32a toward the front of the vehicle.

[0023] The first high beam light source 32a corresponds to the "light source of the main high beam distribution" of the present invention, and the first high beam reflector 32b corresponds to the "light distribution member that distributes light from the light source of the main high beam distribution" of the present invention.

[0024] The low beam reflector 31b and the first high beam reflector 32b are manufactured by integral molding. A partition wall 11w is integrally provided at the boundary between these reflectors 31b, 32b. This partition wall 11w restricts the light from the low beam light source 31a from entering the first high beam reflector 32b, and restricts the light from the first high beam light source 32a from entering the low beam reflector 31b.

[0025] The low beam reflector 31b and the first high beam reflector 32b are covered from the front by a transparent light cover, and the low beam and the high beam are irradiated to the outside of the vehicle through the light cover. The light cover also serves as a front cover that covers the front faces of the left and right first light units 11. The reflectors 31b and 32b are not limited to being integral with each other, and may be separate from each other. The configuration of the irradiating units 31 and 32 including the reflectors 31b and 32b and the shape of each unit may be changed as appropriate.

[0026] The second light unit 12 functions as a second high beam irradiator that irradiates light of a screen light distribution in the upper side light distribution area DH2 shown in Fig. 2. The second light unit 12 includes a second high beam light source 33a and a second high beam reflector 33b that reflects light from the second high beam light source 33a toward the upper side light distribution area DH2 shown in Fig. 2. The second high beam light source 33a and the second high beam reflector 33b are disposed within an area α that is covered from the front by the lamp cover 21 when viewed from the front of the vehicle body.

[0027] The second high beam light source 33a is a known light source such as an LED, is disposed above the second high beam reflector 33b, and emits visible light downward toward the second high beam reflector 33b. The second high beam reflector 33b includes a left first reflector 33L having a reflective surface 33Ls facing the left upper side, and a right second reflector 33R having a reflective surface 33Rs facing the right upper side. For ease of understanding, in FIG. 3, the light from second high beam light source 33a and a portion of the light irradiated to the outside from second light unit 12 are indicated by arrows. In addition, in FIG. 4, the light from second high beam light source 33a and part of the light irradiated to the outside from second light unit 12 are indicated by arrows when front cover 20 is attached.

[0028] The reflecting surface 33Ls of the left first reflector 33L is formed as a reflecting surface that reflects the light incident from the second high beam light source 33a toward the left upper lateral light distribution region DH2. The reflecting surface 33Rs of the right second reflector 33R is formed as a reflecting surface that reflects the light incident from the second high beam light source 33a toward the right upper lateral light distribution region DH2. These left and right reflectors 33L, 33R are integrally manufactured by one-piece molding. Therefore, the number of parts of the second high beam reflector 33b can be reduced, which is advantageous for making the second high beam reflector 33b smaller, reducing costs, and improving assembly. In addition, since the cross-sectional shape of the second high beam reflector 33b is an upwardly convex inverted V shape, it is easier to increase the strength of the second high beam reflector 33b compared to a simple flat plate shape.

[0029] The left and right reflectors 33L, 33R are formed in a symmetrical shape with respect to a plane extending in the front-rear direction about the vehicle center LC. The left first reflector 33L will be described below. FIG. 5 is a diagram showing the left reflector 33L together with the second high beam light source 33a from the left side of the vehicle. The first reflector 33L is curved downward toward the front of the vehicle in a side view of the vehicle shown in Fig. 5, and is curved downward in the vehicle width direction in a front view of the vehicle shown in Fig. 3. Therefore, as shown in Figs. 3 to 5, the light incident on the first reflector 33L from the second high beam light source 33a can be reflected toward the front of the vehicle and toward the outside in the vehicle width direction. This makes it possible to obtain a screen light distribution in the left upper side light distribution area DH2 shown in Fig. 2. In this case, as shown in FIG. 5, the first reflector 33L is arranged to extend in the front-rear direction from behind to the front of the second high beam light source 33a, so that light from the second high beam light source 33a can be incident over a wide range in the front-rear direction, which is advantageous for improving the amount of light in the left upper side light distribution region DH2.

[0030] As shown in FIG. 3, the second high beam light source 33a is arranged at a position overlapping the vehicle center LC in the front view of the vehicle, and the left and right reflectors 33L, 33R are arranged to be distributed to the left and right with respect to the vehicle center LC. This allows the light of the second high beam light source 33a, which is a single light source, to be evenly distributed to the left and right and irradiated. Therefore, the number of parts of the second light unit 12, which is composed of the second high beam light source 33a and the second high beam reflector 33b, can be minimized, which is advantageous for miniaturization, cost reduction, and improvement of assembly of the second light unit 12. In addition, even if the space between the left and right first light units 11 is narrow, the second light unit 12 can be easily arranged.

[0031] Each of the light sources 31a, 32a, and 33a of the light unit 10 is not limited to a point light source, but may be a planar light source that emits planar light by densely arranging a plurality of light emitting elements. The planar light source is, for example, a COB (Chips on Board) type or SMD (Surface Mount Device) type LED. Each of the light sources 31a, 32a, and 33a of this configuration has an output equivalent to that of a light source of a conventional vehicle lamp, and a conventional heat dissipation structure may be applied.

[0032] FIG. 6 is a diagram showing the light unit 10 together with the surrounding configuration, viewed from diagonally front right. 6 shows a case where extensions 41 extending left and right from the vehicle center LC are arranged above the left and right first light units 11. The extensions 41 are components that function as partition members that separate the boundaries of the first light units 11 and as decorative members that contribute to improving the appearance. The extension 41 integrally includes a eaves portion 42 that extends in the vehicle width direction along the upper edge of the light unit 10 and extends forward from the light unit 10, and left and right boundary walls 43 that extend forward from the boundary between the first light unit 11 and the second light unit 12.

[0033] In this configuration, openings 43k are formed in the left and right boundary walls 43 in the areas where the light from the second light unit 12 is incident. These openings 43k enable the left and right light from the second light unit 12 to be irradiated to the outside of the vehicle without being blocked by the extension 41. In addition, in FIG. 5, the opening 43k is shown by a rectangular two-dot chain line, but the shape and size of the opening 43k may be changed as appropriate.

[0034] As described above, the light unit 10 constituting the vehicle lamp has a first light unit 11, as shown in Fig. 3, which has a low beam light source 31a, a first high beam light source 32a, and reflectors 31b, 32b functioning as light distribution members that distribute the light of the light sources 31a, 32a. Also, as shown in Fig. 2, the screen light distribution of the high beam light source of the light unit 10 has a high beam main light distribution area DH1 of the high beam main light distribution and a side upper light distribution area DH2 of the side upper light distribution directed toward the upper sides of the high beam main light distribution. Under the above configuration, the high beam light source of the light unit 10 constitutes a light source of the high beam main light distribution, and has at least one first high beam light source 32a provided on the left and right sides of the vehicle center LC, and a second high beam light source 33a constituting a light source of the side upper light distribution, and the second high beam light source 33a is disposed behind the opaque lamp cover 21 that covers the left and right centers of the left and right first light units 11, and within an area α that overlaps with the lamp cover 21 when viewed from the front of the vehicle. In other words, the second high beam light source 33a is disposed between the transparent covers 22 provided on the left and right sides.

[0035] According to this configuration, the irradiation range of the high beam can be expanded by the side upper light distribution directed to the upper sides of the main high beam light distribution, and a high beam that can improve forward visibility can be obtained. Therefore, compared to the case where the shape of the first high beam reflector 32b is changed to expand the irradiation range of the high beam and the output of the first high beam light source 32a is increased to compensate for the decrease in brightness caused by this shape change, there is no need to increase the output of the first high beam light source 32a, and the size of the heat exhaust structure can be avoided. In addition, an effect that the existing configuration can be easily reused for the first high beam irradiation unit 32 can be expected.

[0036] The light unit 10 also includes at least one transparent cover 22 on each side that transmits light from at least one of the low beam light source 31a and the high beam light source 32a, and the second high beam light source 33a is provided in a region between the left and right transparent covers 22. According to this configuration, the second high beam light source 33a can be disposed by utilizing the space between the left and right transparent covers 22.

[0037] Furthermore, the second high beam light source 33a, which constitutes the light source for the upper side light distribution, is located behind the lamp cover 21 that covers the left and right center of the light unit 10 and overlaps with the lamp cover 21 when viewed from the front of the vehicle, so the second high beam light source 33a can be positioned in a position hidden by the lamp cover 21 while utilizing the space between the left and right first high beam light sources 32a. As a result, it is possible to expand the illumination range of the high beam by the second high beam light source 33a while minimizing changes in size and appearance of the vehicle lamp due to the placement of the second high beam light source 33a, making it easier to achieve, for example, a smart appearance similar to that of a conventional twin-lens type vehicle lamp.

[0038] In addition, since the vehicle equipped with this light unit 10 is a vehicle that tilts left and right when turning, a high beam with a wide illumination range that can illuminate the area ahead can be obtained when the vehicle is turning while tilting. Therefore, a high beam suitable for improving forward visibility when the vehicle is tilting can be obtained. In addition, since it is easier to secure space for arranging components above the second high beam light source 33a, it is easier to arrange certain components 40 (see FIG. 3) such as antennas for an ETC (Electronic Toll Collection System) or communications, radar, cameras, and heat sinks.

[0039] In this configuration, as shown in FIG. 3, there is a second high beam reflector 33b that distributes light from the second high beam light source 33a to the upper side, and the second high beam reflector 33b is located behind the lamp cover 21 and overlaps with the lamp cover 21 when viewed from the front of the vehicle. According to this configuration, the second high beam reflector 33b can be disposed in a position hidden by the lamp cover 21 while utilizing the space between the left and right first high beam light sources 32a. This makes it possible to expand the irradiation range of the high beam by the second high beam reflector 33b while suppressing changes in the size and appearance of the vehicle lamp due to the arrangement of the second high beam reflector 33b.

[0040] The high beam main light distribution area DH1 corresponds to the "first area" of the present invention, the upper side light distribution area DH2 corresponds to the "second area" of the present invention, and the second high beam reflector 33b corresponds to the "second light distribution member" of the present invention.

[0041] In addition, the second high beam reflector 33b reflects the light emitted downward from the second high beam light source 33a toward the upper left and right sides. With this configuration, even if the second high beam light source 33a is a single light source, the second high beam reflector 33b can appropriately distribute and reflect the light of the second high beam light source 33a toward the upper left and right sides. Therefore, the number of light sources and reflectors can be minimized to make the device compact, while the irradiation range of the high beam can be appropriately expanded. Since the device can be made compact, it is easier to prevent changes in size and appearance of the vehicle lamp due to the arrangement of the second high beam reflector 33b.

[0042] In addition, the second high beam reflector 33b is curved toward the front and the outside in the vehicle width direction as it approaches the bottom of the vehicle. This configuration makes it easier to reflect the light of the second high beam light source 33a incident on the second high beam reflector 33b from above toward the front and the outside in the vehicle width direction, which is advantageous for improving the amount of light in the upper side light distribution region DH2.

[0043] The second high beam reflector 33b has a first reflector 33L having a reflective surface 33Ls facing upward on one of the left and right sides, and a second reflector 33R having a reflective surface 33Rs facing upward on the other of the left and right sides, and the first reflector 33L is integrally molded with the second reflector 33R. This configuration reduces the number of parts in the second high beam reflector 33b, which is advantageous for miniaturization, cost reduction, and improved assembly.

[0044] Although the two reflectors 33L, 33R are integrally formed by integral molding, the two reflectors 33L, 33R may be formed as separate bodies. When the two reflectors 33L, 33R are formed as separate bodies, it becomes easier to adjust the shape and position of each reflector 33L, 33R when adjusting the light distribution by each reflector 33L, 33R, and the like, thereby improving the convenience of the vehicle lamp.

[0045] [Second embodiment] Fig. 7 is a front view of the light unit 10 of the saddle-ride type vehicle according to the second embodiment together with the surrounding configuration. Fig. 7 shows a state in which the front cover 20 including the lamp cover 21 has been removed. The second embodiment differs from the first embodiment in the second light unit 12. The same parts as those in the first embodiment are denoted by the same reference numerals, and the different parts will be described.

[0046] 7, the second light unit 12 has, as the second high beam light source 33a, at least one directional light source 33aL that emits light directed to the left side, which is one side of the vehicle width direction, and another directional light source 33aR that emits light directed to the right side, which is the other side of the vehicle width direction. These light sources 33aL and 33aR are disposed below the first high beam light source 32a.

[0047] The second light unit 12 has a first lens 33LL that converts the light of the first directional light source 33aL into control light that spreads toward at least one side in the vehicle width direction, i.e., the left upper side, and a second lens 33LR that converts the light of the second directional light source 33aR into control light that spreads toward the right upper side, i.e., the other side in the vehicle width direction. These lenses 33LL and 33LR constitute a second light distribution member 33c that distributes the light of the two light sources 33aL and 33aR that constitute the second high beam light source 33a into light for left and right upper side distribution.

[0048] Fig. 8 is a diagram showing a schematic view of the light unit 10 from above the vehicle. In Fig. 8, the range of the lamp cover 21 is indicated by a two-dot chain line. As shown in Fig. 8, the one lens 33LL is a convex lens toward the left side, which is one side in the vehicle width direction, and toward the front of the vehicle, and the one directional light source 33aL is disposed inside the one lens 33LL in the vehicle width direction. As a result, light emitted from the one directional light source 33aL to the left side enters the one lens 33LL, and is refracted by the one lens 33LL and emitted, thereby irradiating control light toward the left side and toward the front of the vehicle. Even if the one directional light source 33aL is a light source with strong directionality, the refraction effect of the one lens 33LL converts the light into light directed toward the required range toward the left side and toward the front of the vehicle, which is advantageous for improving the amount of light in the left upper side light distribution region DH2 shown in Fig. 2.

[0049] The other lens 33LR is a convex lens toward the right side, which is the other side in the vehicle width direction, and toward the front of the vehicle, and the other directional light source 33aR is disposed inside the other lens 33LR in the vehicle width direction. As a result, light emitted to the right from the other directional light source 33aR enters the other lens 33LR and is refracted by the other lens 33LR before being emitted, thereby irradiating control light toward the right side and toward the front of the vehicle. Even if the other directional light source 33aR is a light source with strong directionality, the refraction effect of the other lens 33LR can convert it into light that is directed toward the required range toward the right side and toward the front of the vehicle, which is advantageous for improving the amount of light in the right upper side light distribution region DH2 shown in FIG. 2.

[0050] 7 and 8, the second light unit 12 consisting of the one directional light source 33aL, the other directional light source 33aR, the one lens 33LL, and the other lens 33LR is disposed by utilizing the space between the left and right first light units 11. This allows the second light unit 12 to be disposed in a position hidden by the lamp body cover 21 while utilizing the space between the left and right first high beam light sources 32a.

[0051] As described above, in the second embodiment, a lens consisting of one lens 33LL and the other lens 33LR is used to obtain a screen light distribution in the left upper side light distribution area DH2 shown in Fig. 2. This configuration, like the first embodiment, makes it possible to expand the irradiation range of the high beam while suppressing changes in size and appearance of the vehicle lamp, and it is possible to obtain a smart appearance similar to that of a conventional twin-lens type vehicle lamp.

[0052] In addition, the one lens 33LL is a lens that is convex toward one side in the vehicle width direction and toward the front of the vehicle, and the other lens 33LR is a lens that is convex toward the other side in the vehicle width direction and toward the front of the vehicle. With this configuration, even if the one directional light source 33aL and the other directional light source 33aR are light sources with strong directionality, the refraction effect of each lens 33LL, 33LR irradiates the light of each light source 33aL, 33aR toward one side in the vehicle width direction and toward the front of the vehicle, and toward the other side in the vehicle width direction and toward the front of the vehicle, respectively, which is advantageous for improving the amount of light in the left and right upper side light distribution areas DH2.

[0053] Moreover, the one-side directional light source 33aL and the other-side directional light source 33aR constituting the second high beam light source 33a are positioned below the first high beam light source 32a. With this configuration, by positioning the second high beam light source 33a at a low position, it is possible to improve the design freedom and ensure the space for arranging components above the second high beam light source 33a.

[0054] In the second embodiment, as shown in FIG. 7 and FIG. 8, the optical axis direction of the one-way directional light source 33aL is set to face upward and forward on the left side, which is one side of the vehicle width direction, so that the optical axis and light around the optical axis, which have relatively high brightness, can be easily irradiated toward the left upper side light distribution area DH2 shown in FIG. 2. Similarly, as shown in Figures 7 and 8, the optical axis direction of the other directional light source 33aR is set to face upward and forward on the right side, which is the other side of the vehicle width direction, so that the optical axis and light around the optical axis, which have relatively high brightness, can be easily irradiated toward the right upper side light distribution area DH2 shown in Figure 2.

[0055] However, the optical axis directions of the one directional light source 33aL and the other directional light source 33aR do not have to be limited to the above directions, and by adjusting the shape of the lens consisting of the one lens 33LL and the other lens 33LR, a sufficient amount of light can be irradiated toward the left and right upper side light distribution areas DH2 shown in Figure 2.

[0056] [Third embodiment] Fig. 9 is a front view of the light unit 10 of the saddle-ride type vehicle according to the third embodiment together with the surrounding configuration. Fig. 9 shows a state in which the front cover 20 including the lamp cover 21 has been removed. The third embodiment differs from the second embodiment in the orientation of one lens 33LL and the other lens 33LR. The same parts as those in the second embodiment are denoted by the same reference numerals, and the differences will be described.

[0057] The one lens 33LL of the second light unit 12 is a convex lens facing the left side, which is one side of the vehicle width direction, forward and upward of the vehicle. Therefore, even if the light of the one directional light source 33aL is a light source with strong directionality, the refraction effect of the one lens 33LL irradiates the light as a control light facing the left side, forward and upward of the vehicle, which is advantageous for improving the amount of light in the left upper side light distribution region DH2 shown in FIG. 2. In addition, the other lens 33LR of the second light unit 12 is a lens that is convex toward the right side, the front and the top of the vehicle, which is the other side of the vehicle width direction. Therefore, even if the light of the other directional light source 33aR is a light source with strong directionality, the light is irradiated as a control light toward the right side, the front and the top of the vehicle due to the refraction effect of the other lens 33LR, which is advantageous for improving the amount of light in the left upper side light distribution region DH2 shown in FIG. 2.

[0058] 9 illustrates a case in which the optical axis direction of the one directional light source 33aL is set to be upward and forward on the left side, which is one side in the vehicle width direction, and the optical axis direction of the other directional light source 33aR is set to be upward and forward on the right side, which is one side in the vehicle width direction, as in the second embodiment. However, the optical axis directions of the one directional light source 33aL and the other directional light source 33aR do not have to be limited to the above directions, and it is sufficient to irradiate a sufficient amount of light toward the left and right side upper light distribution areas DH2 shown in FIG. 2 by adjusting the shape of the lenses consisting of the one lens 33LL and the other lens 33LR.

[0059] Each of the above-described embodiments shows one aspect of the present invention, and the configuration of details, etc. may be appropriately changed. For example, in each of the above embodiments, the number of the second high beam light sources 33a may be changed. In this case, a reflector or a lens that functions as a second light distribution member may be provided for each second high beam light source 33a, or a common reflector or lens may be provided for the multiple second high beam light sources 33a. In addition, in each of the above embodiments, the present invention has been described as being applied to a vehicle lamp that can obtain a two-eye type appearance, but this is not limited to this, and the present invention may also be applied to a vehicle lamp that can obtain an appearance other than that of a two-eye type. In addition, the convex lens may include not only a convex lens but also a one-sided convex lens or a Fresnel lens, and a person skilled in the art may appropriately select which shape to use.

[0060] Furthermore, the vehicle equipped with the vehicle lamp of the present invention is not limited to a motorcycle, and can be widely applied to vehicles that tilt left and right when turning, for example, a three-wheeled vehicle that tilts left and right when turning. Even if the vehicle is not tilted left and right, for example, when traveling straight, the front left and right can be illuminated by light corresponding to the left and right upper side light distribution areas DH2, thereby improving forward visibility. Therefore, even if a vehicle equipped with the vehicle lamp of the present invention is a vehicle that does not tilt left or right when turning, it is possible to obtain effects such as being able to expand the illumination range of the high beam while minimizing changes in size and appearance of the vehicle lamp due to the placement of the second high beam light source.

[0061] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0062] (Configuration 1) A vehicle lamp having a low beam light source, a high beam light source, and a light distribution member that distributes light from each light source, wherein the screen light distribution of the high beam light source includes a first region of a high beam main light distribution and a second region of an upper side light distribution toward left and right upper sides of the high beam main light distribution, the high beam light source constitutes a light source of the high beam main light distribution and includes a pair of left and right first high beam light sources provided at least one on each side of the center of the vehicle, and one or more second high beam light sources that constitute a light source for the upper side light distribution, and further includes an opaque lamp cover that covers at least either the left or right center of the lamp or the left or right central periphery, and the second high beam light source is a vehicle lamp that is rear of the lamp cover and overlaps with the lamp cover when viewed from the front of the vehicle. According to this configuration, it is possible to expand the illumination range of the high beam by the second high beam light source, while minimizing changes in size and appearance of the vehicle lamp due to the arrangement of the second high beam light source.

[0064] (Configuration 3) The light distribution member has a second light distribution member that distributes light from the second high beam light source into light for the upper side distribution, and the second light distribution member is located behind the lamp cover and overlaps with the lamp cover when viewed from the front of the vehicle. The vehicle lamp described in configuration 1 or 2. According to this configuration, it is possible to expand the illumination range of the high beam by the second light distribution member, while suppressing changes in size and appearance of the vehicle lamp due to the arrangement of the second light distribution member.

[0065] (Configuration 4) The second light distribution member is a reflector that reflects light emitted downward from the second high beam light source toward the upper left and right side portions of the vehicle lamp according to Configuration 3. With this configuration, even if the second high beam light source is a single light source, the light of the second high beam light source can be reflected toward the upper left and right sides by the reflector made of the second light distribution member, making it possible to expand the irradiation range of the high beam while minimizing the number of light sources and reflectors to make the device compact.

[0066] (Configuration 5) The vehicle lamp according to configuration 4, wherein the reflector has a shape that curves forward and outward in a vehicle width direction as it approaches a lower portion of the vehicle. This configuration makes it easier for the light of the second high beam light source incident on the reflector from above to be reflected toward the front of the vehicle and toward the outside in the vehicle width direction, which is advantageous for improving the amount of light distributed to the upper sides of the vehicle. This is advantageous for making the reflector smaller, reducing costs, and improving ease of assembly while ensuring a sufficient amount of light distributed to the upper sides of the vehicle.

[0067] (Configuration 6) The vehicle lamp according to configuration 4 or 5, wherein the reflector includes a first reflector having a reflective surface facing toward the upper side of one of the left and right sides, and a second reflector having a reflective surface facing toward the upper side of the other of the left and right sides, and the first reflector and the second reflector are integrally molded. According to this configuration, the number of parts of the reflector can be reduced, which is advantageous for miniaturization, cost reduction, and improved ease of assembly.

[0068] (Configuration 7) The vehicle lamp according to configuration 4 or 5, wherein the reflector includes a first reflector having a reflective surface facing toward the upper side of one of the left and right sides, and a second reflector having a reflective surface facing toward the upper side of the other of the left and right sides, and the first reflector and the second reflector are provided separately from the lamp. According to this configuration, when adjusting the light distribution by the first reflector and the second reflector, it becomes easier to adjust the shape and position of each reflector, thereby improving the convenience as a vehicle lamp.

[0069] (Configuration 8) The second high beam light source has a one-sided directional light source that emits light directed in one direction in the vehicle width direction when viewed from the front of the vehicle, and a other-sided directional light source that emits light directed in the other direction in the vehicle width direction when viewed from the front of the vehicle, and the second light distribution member has a one-sided lens that converts the light of the one-sided directional light source into control light that spreads toward the upper left or right side, and a other-sided lens that converts the light of the other-sided directional light source into control light that spreads toward the upper left or right side. With this configuration, even if the one directional light source and the other directional light source are highly directional light sources, it becomes easier to irradiate control light that spreads toward the upper left and right sides by the one lens and the other lens, which is advantageous for improving the amount of light distributed toward the upper left and right sides.

According to this configuration, even if the one directional light source and the other directional light source are highly directional light sources, refraction of the convex lens makes it easier to irradiate the light from each light source to one side in the vehicle width direction and forward of the vehicle, and to the other side in the vehicle width direction and forward of the vehicle, which is advantageous for improving the amount of light in the upper light distribution areas on the left and right sides.

[0071] (Configuration 10) A vehicle lamp as described in configuration 8, wherein the one lens is a convex lens in one side of the vehicle width direction, toward the front and upper side of the vehicle, and the other lens is a convex lens in the other side of the vehicle width direction, toward the front and upper side of the vehicle. With this configuration, even if the one directional light source and the other directional light source are highly directional light sources, refraction of the convex lens makes it easier to irradiate the light from each light source in one direction of the vehicle width, in front of and above the vehicle, and in the other direction of the vehicle width, in front of and above the vehicle, which is advantageous for improving the amount of light in the upper left and right side light distribution areas.

[0072] (Configuration 11) The vehicle lamp according to any one of configurations 7 to 9, wherein the second high beam light source is positioned lower than the first high beam light source. According to this configuration, by positioning the second high beam light source lower than the first high beam light source, it is possible to improve design freedom and ensure space for arranging components above the second high beam light source.

[0073] (Configuration 12) The vehicular lamp according to any one of configurations 1, 2, and 4 to 10, wherein the vehicular lamp is a vehicular lamp mounted on a vehicle that tilts left and right when turning. According to this configuration, when turning with the vehicle leaning, a high beam with a wide illumination range capable of illuminating the area ahead can be obtained, thereby improving forward visibility when the vehicle is leaning.
