In addition, in each drawing, the symbol FR indicates the front of the vehicle body, the symbol UP indicates the upper side of the vehicle body, and the symbol LH indicates the left side of the vehicle body.

[0009] [Embodiment Mode] FIG. 1 is a side view of a saddle-ride type vehicle 10 according to an embodiment of the present invention. The saddle-ride type vehicle 10 is a vehicle that includes a body frame 11, a power unit 12 supported by the body frame 11, a front fork 14 that supports a front wheel 13 so as to be steerable, a swing arm 16 that supports a rear wheel 15, and a seat 17 for a passenger. The saddle-ride type vehicle 10 is a vehicle in which a passenger sits astride a seat 17. The seat 17 is provided above the rear part of the body frame 11.

[0010] The body frame 11 includes a head pipe 18 provided at the front end of the body frame 11, a front frame 19 located rearward of the head pipe 18, and a rear frame 20 located rearward of the front frame 19. The front end of the front frame 19 is connected to the head pipe 18. The seat 17 is supported by a rear frame 20 .

[0011] The front forks 14 are supported by a head pipe 18 so as to be steerable to the left and right. The front wheel 13 is supported by an axle 13a provided at the lower end of the front forks 14. A steering handle 21 that is held by the rider is attached to the upper end of the front forks 14.

[0012] The swing arm 16 is supported by a pivot shaft 22 that is supported by the body frame 11. The pivot shaft 22 is a shaft that extends horizontally in the vehicle width direction. The pivot shaft 22 is inserted into the front end of the swing arm 16. The swing arm 16 swings up and down around the pivot shaft 22. The rear wheel 15 is supported by an axle 15 a provided at the rear end of the swing arm 16 .

[0013] The power unit 12 is disposed between the front wheels 13 and the rear wheels 15 and is supported by the body frame 11. The power unit 12 is an internal combustion engine. The power unit 12 includes a crankcase 23 and a cylinder portion 24 that houses a reciprocating piston. An exhaust device 25 is connected to an exhaust port of the cylinder portion 24. The output of the power unit 12 is transmitted to the rear wheels 15 by a driving force transmission member that connects the power unit 12 and the rear wheels 15 .

[0014] The saddle-ride type vehicle 10 also includes a front fender 26 that covers the front wheel 13 from above, a rear fender 27 that covers the rear wheel 15 from above, a step 28 on which a rider places their feet, and a fuel tank 29 that stores fuel used by the power unit 12. The front fender 26 is attached to the front fork 14. The rear fender 27 and the step 28 are provided below the seat 17. The fuel tank 29 is supported by the body frame 11.

[0015] The saddle-ride type vehicle 10 is provided with a vehicle body cover 30 that covers the vehicle body. The vehicle body cover 30 is provided with a front cover 31 that covers the front part of the vehicle body from the front and the left and right sides, and an inner cover 32 that covers the front frame 19 from above. The front cover 31 has a cover shape that widens in the vehicle width direction and up and down direction as it goes rearward, and is formed in a shape that is symmetrical left and right with respect to the center of the vehicle width. A light unit 41 is attached to the front cover 31.

[0016] The light unit 41 is a unit that constitutes part of the lighting equipment of the saddle-ride type vehicle 10, and is also referred to as a headlight unit. The light unit 41 has a front cover 42 that covers the front surface. The front surface of the front cover 42 is formed in a shape that is continuous with the front surface of the front cover 31, that is, it is formed in an inclined shape that slopes rearward the further it moves left and right and up and down from the center of the vehicle width. The front cover 42 includes an outer lens. The light unit 41 is located forward of the center of the saddle-ride type vehicle 10 in the fore-and-aft direction, and more specifically, forward of the steering handlebar 21a and the body frame 11.

[0017] 2 is a front view of the light unit 41 with the front cover 42 removed. The symbol LC in FIG. 2 indicates the center of the vehicle width. As shown in Fig. 2, the light unit 41 has a housing 43 (also referred to as a housing) that extends outward to the left and right with respect to the vehicle width center LC. The housing 43 includes a pair of left and right first low beam irradiators 51, a pair of left and right second low beam irradiators 52 that are arranged outwardly of the vehicle width of each first low beam irradiator 51, and a pair of left and right light irradiators 53. The housing 43 also includes a high beam irradiator (not shown) between the pair of left and right first low beam irradiators 51. The area surrounded by the dashed dotted line in Fig. 2 is a schematic representation of the area where each low beam irradiator 51, 52 emits light. Emitting light means that light is emitted from the vehicle, which is the saddle-ride type vehicle 10.

[0018] The light unit 41, which includes the housing 43 and the irradiation units 51 to 53, is symmetrical with respect to the vehicle width center LC. The components that make up the low beam irradiation units 51 and 52 and the light irradiation unit 53 are housed in the housing 43.

[0019] A pair of left and right first low beam irradiators 51 are provided with a gap between them. Each first low beam irradiator 51 includes a first low beam light source 51a and a first low beam reflector 51b that reflects light from the first low beam light source 51a to produce a low beam. The first low beam light source 51a is a well-known light source such as an LED, and emits visible light. The first low beam reflector 51b is formed as a reflecting mirror that diffuses and reflects light from the first low beam light source 51a toward the front of the vehicle.

[0020] FIG. 3 is a left side view of the housing 43, and FIG. 4 is a perspective view of the housing 43. As shown in FIG. As shown in FIG. 3, the pair of left and right second low beam irradiators 52 are provided on the left and right outer sides and rearward of the pair of left and right first low beam irradiators 51. As shown in FIG. 2, each second low beam irradiator 52 includes a second low beam light source 52a and a second low beam reflector 52b that reflects light from the second low beam light source 52a to produce a low beam. The second low beam light source 52a is a well-known light source such as an LED, and irradiates visible light. The second low beam reflector 52b is formed on a reflecting mirror that diffuses and reflects light from the second low beam light source 52a toward the front of the vehicle. These low beam irradiating units 51 and 52 provide forward illumination required for low beams (so-called passing headlights).

[0021] The housing 43 has an integral ceiling portion 43T (see FIGS. 3 and 4) above the reflectors 51b and 52b and extending forward beyond the reflectors 52a and 52b. The ceiling portion 43T has a first low beam opening 51c (see FIG. 4) that opens toward the first low beam reflector 51b and a second low beam opening 52c (see FIG. 4) that opens toward the second low beam reflector 52b.

[0022] 2, the first low beam light source 51a is located above the first low beam opening 51c (on the opposite side of the first low beam reflector 51b with respect to the first low beam opening 51c). Of the light from the first low beam light source 51a, the light that passes through the first low beam opening 51c is reflected by the first low beam reflector 51b. The second low beam light source 52a is located above the second low beam opening 52c (on the opposite side of the second low beam reflector 52b with respect to the second low beam opening 52c). Of the light from the second low beam light source 52a, the light that passes through the second low beam opening 52c is reflected by the second low beam reflector 52b. The light incident on each of the reflectors 51b and 52b is adjusted by the low beam opening 51c and the second low beam opening 52c.

[0023] A partition wall 43W is provided between the first low beam reflector 51b and the second low beam reflector 52b, and this partition wall 43W separates the first low beam irradiating section 51 from the second low beam irradiating section 52. This partition wall 43W prevents light from the first low beam light source 51a from entering the second low beam reflector 52b, and also prevents light from the second low beam light source 52a from entering the first low beam reflector 51b.

[0024] The pair of left and right light emitting units 53 emit lights LA and LB to improve the visibility of the saddle-ride type vehicle 10 to others outside the vehicle. These lights LA and LB are parallel or quasi-parallel light with a small divergence angle, and as a result, they are light that can achieve higher brightness at a predetermined position away from the saddle-ride type vehicle 10 than low beam or high beam headlight light, which is generally diffused light. This ensures that the lights LA and LB can be distinguished from the headlight light. Therefore, others positioned in the direction in which the lights LA and LB are emitted can easily recognize the lights LA and LB, making it possible to alert others outside the vehicle to the presence of the saddle-ride type vehicle 10. Here, the predetermined position is a position in the direction in which the light LA, LB is irradiated, and can also be referred to as a position farther away than the headlight light or a position away from the irradiation range of the headlight light. The predetermined position includes positions P1, P2 (FIGS. 6 and 7) of another vehicle 111, which will be described later, relative to the saddle-ride type vehicle 10. The light LA, LB can also be referred to as predetermined light, and hereinafter, when the light LA, LB are to be particularly distinguished from each other, they will be referred to as first light LA ​​and second light LB, respectively.

[0025] 2 and 3, the left and right light irradiation units 53 are provided on the left and right inner and outer sides of and in front of the pair of left and right first low beam irradiation units 51. Each light irradiation unit 53 includes a first light source 53a, a first reflector 53b that reflects light from the first light source 53a to become first light LA, and a second reflector 53c that reflects light from the first light source 53a to become second light LB. The first light source 53a is a known light source such as an LED, and emits visible light. The first light source 53a is located further inward in the vehicle width direction than the plurality of light sources 51a, 52a of each low beam irradiation unit 51, 52, and is located further forward and lower than these light sources 51a, 52a. These light sources 51a, 52a, 53a are located further forward than the handlebar 21a and the body frame 11. These light sources 51a, 52a, and 53a are not limited to point light sources, but may be planar light sources in which a plurality of light emitting elements are densely arranged to emit planar light. The planar light source is, for example, a COB (Chips on Board) type or an SMD (Surface Mount Device) type LED.

[0026] The first reflector 53b and the second reflector 53c are positioned forward and below the light sources 51a, 52a and other reflectors 51b, 52b of each low beam irradiation unit 51, 52, and are supported by the housing 43, so they are positioned forward of and between the left and right headlight light sources consisting of the low beam light source 51a and the high beam light source 52a. 2, the ceiling portion 43T of the housing 43 has a first opening 53d that opens in the vertical direction below the first light source 53a and above the first reflector 53b and the second reflector 53c. As shown in Fig. 3, the first opening 53d is located behind the light irradiation unit 53 that includes the first reflector 53b and the second reflector 53c. Of the light from the first light source 53a, the light that passes through the first opening 53d is reflected by the first reflector 53b and the second reflector 53c.

[0027] The first reflector 53b is formed as a reflecting mirror that irradiates light from the first light source 53a in a predetermined direction, which is set to a direction suitable for improving the visibility of the saddle-ride type vehicle 10 from outside the vehicle. In addition, the irradiation angle range of the first light LA ​​can be changed by moving the first reflector 53b closer to or farther away from the first light source 53a. By changing the irradiation angle range or brightness, it is also possible to change the cross-sectional area of ​​the first light LA ​​that has a predetermined brightness or higher.

[0028] For example, when it is desired that the first light LA ​​be perceived by others for only a short time or when it is important that the first light LA ​​be perceived by others who are far away, it is preferable to set the position of the first reflector 53b, etc. so as to narrow the irradiation angle range. Also, when it is important that the light LA ​​be perceived by others who are located in a relatively wide range or nearby, it is preferable to set the position of the first reflector 53b, etc. so as to widen the irradiation angle range. Also, the irradiation angle range may be changed by changing the shape of the first reflector 53b.

[0029] Furthermore, when the first light LA ​​is converted into parallel light by the first reflector 53b, the first reflector 53b may be, for example, a reflecting mirror having a paraboloid of revolution with the position of the first light source 53a as its focus, on the reflecting surface of which an area is formed that can irradiate light LA ​​of a predetermined width in a desired direction. Furthermore, to make the first light LA ​​quasi-parallel, for example, the reflecting surface of the first reflector 53b may be a reflecting surface that approximates a paraboloid of revolution. Quasi-parallel light is divergent light that is close to parallel light. Since quasi-parallel light has a small divergence angle, it can irradiate light with a certain brightness or more over a relatively long distance, similar to parallel light.

[0030] The second reflector 53c is formed as a reflecting mirror that irradiates the light from the first light source 53a in a predetermined direction. This direction is set to face other people (illumination targets) to improve the visibility of the saddle riding type vehicle 10. As in the case of the first reflector 53b, by adjusting the position or changing the shape of the second reflector 53c, it is possible to change the irradiation angle range of the second light LB, increase or decrease the cross-sectional area of ​​the second light LB (corresponding to the cross-sectional area having a predetermined level of brightness (e.g., illuminance or brightness that can be recognized by others)), or make the second light LB a parallel light, quasi-parallel light, etc.

[0031] 2 illustrates an example in which there is one first light source 53a for the light LA ​​and the light LB, but a light source may be provided for each of the light LA ​​and the light LB. When a light source is provided for each of the light LA ​​and the light LB, the brightness and illuminance of the light LA ​​and the light LB can be easily changed.

[0032] <About optical LA and LB> The lights LA and LB will now be explained. As described above, the light LA ​​and LB are lights that can obtain a higher brightness in the direction in which they are irradiated than the headlight light, which is diffused light. The light beams LA and LB will be explained in relation to the driving situation. FIG. 5 is a diagram showing a traveling situation in which a plurality of vehicles are traveling, as viewed from above. Figure 5 shows an intersection (also called a crossroads) 100 where two roads intersect, along with its surroundings. The road including lane 101A on which another vehicle 111 (hereinafter referred to as "other vehicle 111") is traveling is referred to as "first road 101," and the road that intersects with first road 101 is referred to as "second road 102."

[0033] As an example of the saddle-ride type vehicle 10 of this embodiment, vehicles 10A and 10B consisting of motorcycles positioned at an intersection 100 are shown. Vehicle 10A is positioned on a second road 102 and is about to turn left onto lane 101A (the lane on which another vehicle 111 is traveling) of a first road 101. Vehicle 10B is positioned on the opposite lane (also called an oncoming road) 101B from lane 101A on which the other vehicle 111 is traveling and is about to make a U-turn at the intersection 100 or turn right onto the second road 102. Reference numeral 105 in Fig. 5 denotes a stop line where vehicle 10A will stop.

[0034] FIG. 6 is a diagram showing the vehicle 10A together with another vehicle 111 from above. As shown in FIG. 6, the vehicle 10A emits light beams LA and LB in directions at angles θ1 and θ2 corresponding to the front lateral sides of the vehicle. Angle θ1 is the direction in which the first light LA ​​is emitted toward the driver of the other vehicle 111 when the other vehicle 111 is at position P1 on the lane 101A, and Fig. 6 illustrates a case in which the angle is to the front side of the vehicle 10A relative to the vehicle 10A. Angle θ2 is the direction in which the second light LB is emitted toward the driver of the other vehicle 111 when the other vehicle 111 is at position P2 on the lane 101A, and Fig. 6 illustrates a case in which the angle is to the front side of the vehicle 10A relative to the vehicle 10A. The other vehicle 111 is a vehicle that may follow the vehicle 10A after the vehicle 10A makes a left turn. As shown in FIG. 6, position P2 corresponds to a position closer to the vehicle 10A in the vehicle width direction than position P1.

[0035] Positions P1 and P2 are set based on simulations and experiments as suitable positions for other vehicle 111 to avoid contact with vehicle 10A. For example, positions P1 and P2 are set as positions where other vehicle 111 can avoid contact with vehicle 10A or where other vehicle 111 can stop. Position P1 is the position of other vehicle 111 before it reaches position P2. If position P1 is defined as a separation distance d1 from vehicle 10A and position P2 is defined as a separation distance d2 from vehicle 10A, then separation distance d1>separation distance d2.

[0036] By the vehicle 10A emitting the light LA ​​and LB in the directions of the angles θ1 and θ2, respectively, the first light LA ​​is emitted toward the position P1, and the second light LB is emitted toward the position P2. This allows the light LA ​​and LB to be emitted toward the driver of the other vehicle 111 that may be a following vehicle, making the driver of the other vehicle 111 aware of the presence of the vehicle 10A. Furthermore, since the lights LA and LB are emitted from in front of the steering handlebar 21a (see FIG. 1), the lights LA and LB are not blocked by a passenger positioned behind the handlebar 21a, i.e., a passenger of the vehicle 10A.

[0037] 6, the lights LA and LB can be perceived by the driver of the other vehicle 111 at different positions P1 and P2, so the lights LA and LB can be recognized by the driver of the other vehicle 111 at a time interval. This allows the lights LA and LB to be perceived by the driver of the other vehicle 111 as flashing lights, making it easier for the driver of the other vehicle 111 to recognize the vehicle 10A. In this configuration, as shown in Fig. 3, the light emitting unit 53 that emits light LA ​​and LB is provided at a position near the front of the vehicle 10A. Since the vehicle 10A is a moving vehicle, there are usually no obstacles ahead where the vehicle 10A is traveling, but as shown in Fig. 6, there may be an obstacle 200 on the side of the vehicle 10A. The obstacle 200 in Figure 6 is assumed to be another saddle-type vehicle located to the right of vehicle 10A, but obstacle 200 is not limited to a vehicle and could also be a fence or plant located to the left of vehicle 10A, and depending on the road and surrounding environment, an obstacle may exist to the right of vehicle 10A.

[0038] In this configuration, the lights LA and LB are emitted from a position closer to the front of the vehicle 10A, so even if there are obstacles 200 on the left and right of the vehicle 10A, the lights LA and LB are more easily irradiated without being blocked by the obstacles 200 on the sides of the vehicle 10A, as illustrated in FIG. 6, compared to when the lights LA and LB are emitted from a position closer to the rear of the vehicle 10A. Even if the obstacle 200 is located in a position that blocks the light LA, the light LB is emitted further forward than the light LA, so it is more easily irradiated without being blocked by the obstacle 200. Furthermore, compared to when the lights LA and LB are emitted from a position closer to the rear of the vehicle 10A, the lights LA and LB can be emitted from a position closer to the other vehicle 111. That is, due to the positional relationship between the position of the host vehicle, which is the vehicle 10A, and the obstacle 200 present to the side of the host vehicle, the lights LA and LB are unlikely to be blocked by the obstacle 200. As a result, even if the obstacle 200 is present, the lights LA and LB make it easier for the driver of the other vehicle 111 to be aware of the presence of the vehicle 10A.

[0039] FIG. 7 is a diagram showing the vehicle 10B together with another vehicle 111 from above. As shown in FIG. 7, the vehicle 10B emits light beams LA and LB in directions at angles θ3 and θ4, respectively, which correspond to the front lateral directions of the vehicle. Angle θ3 is the direction in which the first light LA ​​is emitted toward the driver of the other vehicle 111 when the other vehicle 111 is at position P1 on the lane 101A. Also, angle θ4 is the direction in which the second light LB is emitted toward the driver of the other vehicle 111 when the other vehicle 111 is at position P2 on the lane 101A. The other vehicle 111 is an oncoming vehicle of vehicle 10B. As shown in FIG. 7, position P2 corresponds to a position closer to the vehicle 10A in the longitudinal direction of the vehicle than position P1.

[0040] Positions P1 and P2 are set based on simulations and experiments as suitable positions for the other vehicle 111 to avoid contact with vehicle 10B. For example, positions P1 and P2 are set as positions where the other vehicle 111 can avoid contact with vehicle 10B or where the other vehicle 111 can stop. As in the case of FIG. 6, position P1 is the position of the other vehicle 111 before it reaches position P2. If position P1 is defined as a separation distance d1 from vehicle 10B and position P2 is defined as a separation distance d2 from vehicle 10B, then separation distance d1>separation distance d2.

[0041] Therefore, by vehicle 10B emitting light LA ​​and light LB in the directions of angles θ3 and θ4, respectively, the first light LA ​​is emitted toward position P1 and the second light LB is emitted toward position P2. This allows light LA ​​and LB to be emitted toward the driver of another vehicle 111, an oncoming vehicle, and makes the driver of the other vehicle 111 aware of the presence of vehicle 10A. Furthermore, since the lights LA and LB are emitted from in front of the steering handlebar 21a (see FIG. 1), the lights LA and LB are not blocked by a passenger positioned behind the handlebar 21a, i.e., a passenger of the vehicle 10B.

[0042] 7, the lights LA and LB can be perceived by the driver of the other vehicle 111 at different positions P1 and P2, so the lights LA and LB can be recognized by the driver of the other vehicle 111 at a time interval. This allows the lights LA and LB to be perceived by the driver of the other vehicle 111 as flashing lights, making the driver of the other vehicle 111 more aware of the presence of the vehicle 10A. Furthermore, in this configuration, as shown in Fig. 3, the light emitting unit 53 that emits the lights LA and LB is provided at a position closer to the front of the vehicle 10B. Therefore, even if an obstacle 201 (for example, a fence or a plant) that blocks the light is present to the side of the vehicle 10B as shown in Fig. 7, the lights LA and LB are not blocked by the obstacle 201, making it easier to irradiate the lights LA and LB, and the lights LA and LB can be emitted from a position closer to the other vehicle 111. In other words, due to the positional relationship between the position of the host vehicle, which is the vehicle 10B, and the obstacle 201 that exists to the side of the host vehicle, the lights LA and LB are less likely to be blocked by the obstacle 201. As a result, the lights LA and LB make it easier for the driver of the other vehicle 111 to be aware of the presence of the vehicle 10B.

[0043] 6 and 7, the first light LA ​​is light that reaches the driver of the other vehicle 111 that is relatively far away, and the second light LB is light that reaches the driver of the other vehicle 111 that is relatively close, so the first light LA ​​can be described as "light that reaches far from the vehicle," and the second light LB can be described as "light that reaches near the vehicle." In addition, the second light LB is also light that reaches closer to the center of the vehicle width of the vehicles 10A and 10B than the first light LA.

[0044] 8 is a diagram showing a situation in which pedestrians M1 are present on the left and right sides in front of a traveling saddle-ride type vehicle 10. It is assumed that the pedestrians M1 are facing the road 107 on which the saddle-ride type vehicle 10 is traveling. 8, the light emitting unit 53 emits light LA ​​and LB toward the sides in front of the vehicle, which can make pedestrians M1 present on the left and right sides in front of the vehicle 1 more aware of the presence of the saddle type vehicle 10. Therefore, not only the occupants of other vehicles 111 but also pedestrians M1 around the saddle type vehicle 10 can easily recognize the saddle type vehicle 10.

[0045] Figure 8 shows a schematic diagram of the central visual field MC and peripheral visual field MS of a person (pedestrian M1). The central visual field MC is the range that can be seen without moving the eyes, and the peripheral visual field MS is the range of vision outside the central visual field MC. It is known that a characteristic of human vision is that the central visual field MC allows the shape of surrounding objects to be clearly distinguished, but the reaction to the movement of those objects tends to be relatively slow. It is also known that the peripheral visual field MS does not allow the shape of surrounding objects to be clearly distinguished, but the reaction to the movement of those objects tends to be relatively fast. In this configuration, when the saddle-ride type vehicle 10 and the pedestrian M1 are in a positional relationship as shown in Fig. 8, the saddle-ride type vehicle 10 can irradiate the light LA ​​and LB toward the peripheral visual field MS of the pedestrian M1. This is expected to have the effect of making it easier for the pedestrian M1 to recognize the saddle-ride type vehicle 10.

[0046] In this configuration, the brightness α of each light LA, LB and the cross-sectional area β of a predetermined illuminance or more are set as follows: The brightness α is set within a range of brightness that can be perceived by others present at positions P1, P2 shown in Figures 6 and 7. The cross-sectional area β of a predetermined illuminance or more can also be said to be a cross-sectional area of ​​illuminance that can be perceived by others present at positions P1, P2, and is set within a range that can be perceived by the others.

[0047] <Brightness α and cross section β of light LA ​​and LB> FIG. 9 is a diagram showing an example of the specifications of the brightness α and cross-sectional area β of the lights LA and LB. 9 define at least one of the magnitude of the brightness α and the magnitude of the cross-sectional area β. In the saddle-ride type vehicle 10, the brightness α and the cross-sectional area β of the lights LA and LB are set to satisfy one of the specifications. However, the brightness α and cross-sectional area β of the first light LA ​​shown in Fig. 9 indicate the brightness and cross-sectional area at position P1, that is, the brightness and cross-sectional area of ​​the position P1 where the first light LA ​​is irradiated relative to the other. Also, the brightness α and cross-sectional area β of the second light LB shown in Fig. 9 indicate the brightness and cross-sectional area at position P2, that is, the brightness and cross-sectional area of ​​the position P2 where the second light LA ​​is irradiated relative to the other.

[0048] 9, a high brightness α indicates that the brightness exceeds a predetermined brightness, and a low brightness α indicates that the brightness falls below the predetermined brightness. Also, a high cross-sectional area β indicates that the cross-sectional area at a predetermined illuminance or higher exceeds the predetermined area, and a low cross-sectional area β indicates that the cross-sectional area at a predetermined illuminance or higher falls below the predetermined area. Here, the predetermined luminance is a reference value for determining whether the luminance is large or small, and is set to an appropriate value within a range that satisfies the condition for the luminance α to be recognizable by others outside the vehicle. The predetermined illuminance is also set to an appropriate value within a range that satisfies the condition for the illuminance to be recognizable by others outside the vehicle. The predetermined area is also a reference value for determining whether the cross-sectional area β is large or small, and is set to an appropriate value within a range that satisfies the condition for the area to be recognizable by others outside the vehicle.

[0049] Generally, luminance indicates brightness per unit area when viewed from a certain direction, and the luminance of light LA, LB indicates brightness per unit area when the light LA, LB is viewed from the direction in which each light LA, LB is emitted. Also, generally, illuminance indicates brightness per unit area of ​​the irradiated surface, and the illuminance of light LA, LB indicates brightness per unit area that will illuminate the eyes of a person outside the vehicle as assumed in advance. Fig. 9 also shows a schematic diagram of the irradiation states of light LA ​​and LB for each specification. In the irradiation states shown in Fig. 9, light with a high brightness α is shown by a solid line, and light with a low brightness α is shown by a dashed line. Furthermore, light with a large cross-sectional area β is shown by a thick line, and light with a small cross-sectional area β is shown by a thin line.

[0050] In specification 1 shown in Fig. 9, the first light LA ​​has a high luminance α and a small cross-sectional area β, and the second light LB has a low luminance α and a small cross-sectional area β. In specification 1, the first light LA ​​can provide a sufficient optical stimulus to another person at a distant position P1. Furthermore, after the optical stimulus by the first light LA, the glare (equivalent to a bright light stimulus) can be reduced when the other person moves from position P1 to a relatively close position P2 and captures the second light LB in the central visual field MC, etc. This reduces the glare to another person at position P2, while improving the visibility of the saddle-ride type vehicle 10 by the first and second lights LA and LB.

[0051] In specification 2, the luminance α of the first light LA ​​is low, and the luminance α of the second light LB is high. The cross-sectional areas β of the light LA ​​and LB are not limited and may be set to any appropriate value. In specification 2, the first light LA ​​allows others located within the irradiation range of the first light LA, including position P1, to perceive the light at a position closer to the central visual field MC the further away they are, and a sufficient amount of change in light (contrast difference) can be ensured in a dark environment, such as at night. Because the contrast difference is ensured, the light stimulus is suppressed while the other person at position P1 easily notices the light LA. Furthermore, the second light LB can provide a sufficient light stimulus to the other person at position P2. Therefore, even after the other person who moves from position P1 to position P2 perceives the first light LA, which ensures a contrast difference, a sufficient light stimulus can be provided, making it easier for the other person at position P2 to notice the light LB. This improves the visibility of the saddle-ride type vehicle 10 using the first and second lights LA and LB.

[0052] In specification 3, the brightness α of the first light LA ​​is high, and the brightness α of the second light LB is low. The cross-sectional areas β of the lights LA and LB are not limited and may be set to any appropriate value. In the case of specification 3, the first light LA ​​can provide a sufficient optical stimulus to others at a distant position P1. This makes it easier for others to recognize the saddle-ride type vehicle 10 at an early stage. In addition, the glare caused by the second light LB to others at position P2 can be reduced. This makes it possible to improve the visibility of the saddle-ride type vehicle 10 by the first and second lights LA and LB while reducing glare.

[0053] In specification 4, the cross-sectional area β of the first light LA ​​is large, and the cross-sectional area β of the second light LB is small. Note that the brightness α of the lights LA and LB is not limited and may be set to an appropriate value. In specification 4, the first light LA ​​allows others to perceive the light over a wide range of positions, including position P1 and its surroundings. Therefore, it becomes easier for others to recognize the saddle-ride type vehicle 10 at an earlier timing than when they reach position P1. Furthermore, the second light LB allows others at position P2 to perceive light for a short period of time, thereby providing sufficient optical stimulation to others at position P2 and making it easier for others to recognize the saddle-ride type vehicle 10 more reliably. Therefore, it becomes easier for others outside the vehicle to perceive the saddle-ride type vehicle 10 at an earlier timing from distant positions, and easier for others to recognize the saddle-ride type vehicle 10 more reliably from positions close to the saddle-ride type vehicle 10. Furthermore, it becomes easier for others who move from position P1 to position P2 to perceive long-duration light and short-duration light, which also makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10. This improves the visibility of the saddle type vehicle 10 by the first and second lights LA and LB.

[0054] In specification 5, the cross-sectional area β of the first light LA ​​is small, and the cross-sectional area β of the second light LB is large. Note that the brightness α of the lights LA and LB is not limited and may be set to an appropriate value. In specification 5, the first light LA ​​allows others at position P1 to perceive light for a short period of time. Therefore, sufficient light stimulus can be provided to others, making it easier for others to recognize the saddle-ride vehicle 10 from a distant location. Furthermore, even when position P1 is set to a more distant location, others can easily recognize the saddle-ride vehicle 10. Furthermore, the second light LB allows others to perceive light from a wide range of locations, including position P2 and its surroundings, making it easier for others to recognize the saddle-ride vehicle 10 at an earlier timing than when it reaches position P2. Therefore, it becomes easier for others outside the vehicle to more reliably recognize the saddle-ride vehicle 10 from a distant location, and easier for others to recognize the saddle-ride vehicle 10 at an earlier timing when they are close to the saddle-ride vehicle 10. Furthermore, a person who moves from position P1 to position P2 can perceive the short-term light and the long-term light, which also makes it easier for people outside the vehicle to recognize the saddle-ride type vehicle 10. This improves the recognizability of the saddle-ride type vehicle 10 by the first and second lights LA and LB.

[0055] In specification 6, the first light LA ​​has a high brightness α and a large cross-sectional area β, and the second light LB has a low brightness α and a small cross-sectional area β. Specification 6 corresponds to a combination of specifications 3 and 4. Therefore, in specification 6, the first light LA ​​can provide sufficient optical stimulus to others over a wide range of positions, including position P1 and its surroundings. This makes it easier for others to recognize the saddle-ride type vehicle 10 more reliably at a timing earlier than the timing when others reach position P1. Furthermore, while suppressing the glare caused by the second light LB to others at position P2, the second light LB can provide sufficient optical stimulus to others at position P2, making it easier for others to recognize the saddle-ride type vehicle 10 more reliably. Furthermore, because it is possible for others who move from position P1 to position P2 to perceive long-duration light and short-duration light, this also makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10. This improves the recognizability of the saddle-ride type vehicle 10 by the first and second lights LA and LB.

[0056] In specification 7, the brightness α of the first light LA ​​is high and the cross-sectional area β is small, and the brightness α of the second light LB is low and the cross-sectional area β is large. Specification 7 corresponds to a combination of specifications 3 and 5. Therefore, in specification 6, the first light LA ​​can provide a sufficient optical stimulus to others at position P1 and allow them to perceive the light for a short period of time. This makes it easier for others to recognize the saddle-ride type vehicle 10 from a distant location. Furthermore, even when position P1 is set to a more distant location, others can easily recognize the saddle-ride type vehicle 10. Furthermore, while suppressing glare from the second light LB in a wide range of locations including position P2 and its surroundings, the second light LB allows others to perceive light from a wide range of locations including position P2 and its surroundings. Therefore, while suppressing glare, it is easier for others to recognize the saddle-ride type vehicle 10 at a timing earlier than the timing when others reach position P2. Therefore, it becomes easier for others outside the vehicle to more reliably recognize the saddle-ride type vehicle 10 from a distant position, and easier for others outside the vehicle to recognize the saddle-ride type vehicle 10 at an early timing when they are close to the saddle-ride type vehicle 10. Furthermore, it is possible for others who move from position P1 to position P2 to perceive the short-term light and the long-term light, which also makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10. This improves the recognizability of the saddle-ride type vehicle 10 by the first and second lights LA and LB.

[0057] In specification 8, the first light LA ​​has a low luminance α and a large cross-sectional area β, and the second light LB has a high luminance α and a small cross-sectional area β. Specification 8 corresponds to a combination of specifications 2 and 4. Therefore, in specification 8, the first light LA ​​allows others located within the irradiation range of the first light LA, including position P1, to perceive the light at positions closer to the central visual field MC the further away they are, and also allows others to perceive the light at a wide range of positions including position P1 and its surroundings. Therefore, the light that suppresses optical stimuli and ensures a sufficient change in light amount (contrast difference) makes it easier for others to recognize the saddle-ride type vehicle 10 at a timing earlier than the timing when the others reach position P1. Furthermore, the second light LB can provide sufficient optical stimulus to others at position P2 even after they perceive the first light LA, which ensures a contrast difference, and allows them to perceive light for a short period of time, making it easier for others to recognize the saddle-ride type vehicle 10 more reliably. Therefore, it becomes easier for others outside the vehicle to recognize the saddle-ride type vehicle 10 at an early stage while suppressing light irritation at distant positions, and it becomes easier for others outside the vehicle to recognize the saddle-ride type vehicle 10 more reliably at positions closer to the saddle-ride type vehicle 10. Furthermore, it is possible to cause others who move from position P1 to position P2 to perceive long-duration light and short-duration light, which also makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10. This makes it possible to improve the recognizability of the saddle-ride type vehicle 10 by the first and second lights LA, LB.

[0058] In specification 9, the luminance α of the first light LA ​​is low and the cross-sectional area β is small, and the luminance α of the second light LB is high and the cross-sectional area β is large. Specification 9 corresponds to a combination of specifications 2 and 5. Therefore, in specification 9, the first light LA ​​allows others located within the irradiation range of the first light LA, including position P1, to perceive light at positions closer to the central visual field MC the further away they are, and allows others at position P1 to perceive light for a short period of time. Therefore, a sufficient optical stimulus can be provided to others with a short period of time that ensures a sufficient change in light (contrast difference), making it easier for others to recognize the saddle-ride type vehicle 10 from a distant position. Furthermore, even when position P1 is set to a more distant position, others can more easily recognize the saddle-ride type vehicle 10. Furthermore, the second light LB can provide sufficient optical stimulus to others at a wide range of positions, including position P2 and its surroundings, even after they perceive the first light LA ​​with a sufficient contrast difference. Therefore, others can more easily recognize the saddle-ride type vehicle 10 before they reach position P2. Therefore, it becomes easier for others outside the vehicle to more reliably recognize the saddle-ride type vehicle 10 from a distant position, and easier for others outside the vehicle to recognize the saddle-ride type vehicle 10 at an early timing when they are close to the saddle-ride type vehicle 10. Furthermore, it is possible for others who move from position P1 to position P2 to perceive the short-term light and the long-term light, which also makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10. This improves the recognizability of the saddle-ride type vehicle 10 by the first and second lights LA and LB.

[0059] As described above, the light unit 41 constituting the lighting device emits, at position P1, a first light LA ​​that has a higher brightness than the headlight light of the vehicle itself, which is the saddle-ride type vehicle 10, and, at position P2, a second light LB that has a higher brightness than the headlight light of the vehicle itself. Here, position P1 corresponds to a "predetermined first position" of the present invention. Position P2 corresponds to a second position that is closer to the host vehicle in the longitudinal direction or the width direction than position P1 (see FIGS. 6 and 7). At least one of the luminance α and the cross-sectional area β of the first light LA ​​at the position P1 is different from at least one of the luminance α and the cross-sectional area β of the second light LB at the position P2. At position P1, first light LA, which has a higher brightness than the headlight light of the saddle-ride type vehicle 10, is emitted, and at position P2, second light LB, which has a higher brightness than the headlight light of the saddle-ride type vehicle, is emitted, so that others present at positions P1 and P2 can easily perceive the light LA ​​and LB. Moreover, at least one of the brightness α and cross-sectional area β of the first light LA ​​at position P1 is different from at least one of the brightness α and cross-sectional area β of the second light LB at position P2. Therefore, others who move from position P1 to position P2 can perceive two types of light with different brightness α and / or long-duration light and short-duration light due to the light LA ​​and LB, making it easier for others to notice the light. As a result, the first and second lights LA and LB make it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10.

[0060] Furthermore, as described in Specifications 2, 8, and 9, the luminance α of the first light LA ​​at the first position P1 is smaller than the luminance α of the second light LB at the second position P2. Therefore, the first light LA ​​allows others located within the irradiation range of the first light LA, including position P1, to perceive light at positions closer to the central visual field MC the further away they are, making it easier to ensure a contrast difference resulting from the amount of change in light. Furthermore, the second light LB can provide sufficient optical stimulus to others located at position P2. Therefore, even after perceiving the first light LA, which ensures a contrast difference, sufficient optical stimulus can be provided to others who move from position P1 to position P2, making it easier for others located at position P2 to notice the light LB. This makes it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10.

[0061] Furthermore, as described in Specifications 1, 3, 6, and 7, the brightness α of the first light LA ​​at the first position P1 is greater than the brightness α of the second light LB at the second position P2, so the first light LA ​​can provide sufficient optical stimulus to others at position P1, making it easier for others to recognize the saddle-ride type vehicle 10 at an early stage. Also, glare for others at position P2 can be reduced. As a result, the first and second lights LA and LB make it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10 while reducing glare for others.

[0062] Furthermore, as described in Specifications 5, 7, and 9, the cross-sectional area β of the first light LA ​​at the first position P1 is smaller than the cross-sectional area β of the second light LB at the second position P2. Therefore, the first light LA ​​can cause others at position P1 to perceive light for a short period of time, providing sufficient light stimulation to others and making it easier for others to recognize the vehicle from a distant location. Furthermore, even when position P1 is set to a more distant location, others can easily recognize the saddle-ride type vehicle 10. Furthermore, the second light LB can cause others to perceive light from a wide range of locations, including position P2 and its surroundings, making it easier for others to recognize the saddle-ride type vehicle 10 at an earlier timing than when the saddle-ride type vehicle 10 reaches position P2. Therefore, it becomes easier for others outside the vehicle to more reliably recognize the saddle-ride type vehicle 10 from a distant location, and easier for others to recognize the saddle-ride type vehicle 10 at an earlier timing when they are close to the saddle-ride type vehicle 10. Furthermore, a person who moves from position P1 to position P2 can perceive the light for a short period of time and the light for a long period of time, which also makes it easier for other people outside the vehicle to recognize the saddle type vehicle 10.

[0063] Furthermore, as described in Specifications 4, 6, and 8, the cross-sectional area β of the first light LA ​​at the first position P1 is larger than the cross-sectional area β of the second light LB at the second position P2. Therefore, the first light LA ​​can be perceived by others at a wide range of positions, including position P1 and its surroundings, making it easier for others to recognize the saddle-ride type vehicle 10 at an earlier timing than when the vehicle reaches position P1. Furthermore, the second light LB can be perceived by others at position P2 for a short period of time, providing sufficient optical stimulation to others, making it easier for others to recognize the vehicle. Therefore, others outside the vehicle can recognize the saddle-ride type vehicle 10 at an earlier timing from distant positions, and can recognize the saddle-ride type vehicle 10 more reliably from positions close to the saddle-ride type vehicle 10. Furthermore, it is possible for others who move from position P1 to position P2 to perceive both long-duration light and short-duration light, making it easier for others outside the vehicle to recognize the saddle-ride type vehicle 10.

[0064] The above-described embodiment is merely an example of one aspect of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention. For example, the present invention is not limited to the motorcycle shown in Fig. 1, but may be applied to various saddle-ride type vehicles including three-wheeled and four-wheeled types, or to any vehicle such as a four-wheeled vehicle. Fig. 10 is a diagram schematically showing first and second lights LA, LB emitted from a four-wheeled vehicle 10C. As shown in Fig. 10, a pair of light units 41 are attached to the front of the four-wheeled vehicle 10C with a gap between them on the left and right, and the first and second lights LA, LB are emitted from each light unit 41. This improves the visibility of the four-wheeled vehicle 10C from drivers of other vehicles, pedestrians, etc.

[0065] Furthermore, the direction of the lights LA and LB is not limited to the front and lateral directions of the vehicle, and may be any direction that is suitable for passengers of other vehicles and pedestrians to recognize the vehicle 10. Furthermore, the number of lights LA and LB may be increased or decreased.

[0066] In this explanation, the brightness on the exit side of the light LA ​​and LB is expressed as "brightness α," and the brightness of the irradiation surface onto which the light LA ​​and LB are irradiated is expressed as "illuminance." However, instead of "brightness α," the indicator indicating the brightness on the exit side may be replaced with "luminous flux," which is the amount of light per unit time, or "luminous intensity," which indicates the strength of light in a certain direction.

[0067] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0068] (Configuration 1) A vehicle having a lighting device, the lighting device irradiates a first light at a predetermined first position, the first light having a brightness higher than the headlight light of the vehicle, and a second light at a second position closer to the vehicle in the fore-and-aft direction or the width direction than the first position, the second light having a brightness higher than the headlight light, and at least one of the brightness of the first light and the cross-sectional area having a predetermined illuminance or more at the first position is different from at least one of the brightness of the second light and the cross-sectional area having a predetermined illuminance or more at the second position. At the first position, a first light having a higher brightness than the headlight light of the host vehicle is emitted, and at the second position, a second light having a higher brightness than the headlight light of the host vehicle is emitted, making it easier for others present at the first and second positions to perceive the light. Furthermore, at least one of the brightness and cross-sectional area of ​​the first light at the first position that is equal to or greater than a predetermined illuminance is different from at least one of the brightness and cross-sectional area of ​​the second light at the second position that is equal to or greater than the predetermined illuminance. Therefore, others who move from the first position to the second position can perceive two types of light with different brightnesses and / or long-duration light and short-duration light, making it easier for others to notice the light. This allows the first and second lights to make it easier for others outside the vehicle to recognize the vehicle.

[0069] (Configuration 2) The vehicle described in Configuration 1, wherein the brightness of the first light at the first position is less than the brightness of the second light at the second position. According to this configuration, the first light allows others located within the illumination range of the first light, including the first position, to perceive the light at a position closer to the central visual field the further away they are, and it is easier to ensure a contrast difference resulting from the change in light. Furthermore, the second light provides sufficient optical stimulus to others at the second position. Therefore, even after perceiving the first light, which ensures a contrast difference, a sufficient optical stimulus can be provided to others who move from the first position to the second position, making it easier for others at the second position to notice the light. This makes it easier for others outside the vehicle to recognize the vehicle.

[0070] (Configuration 3) The vehicle described in configuration 1, wherein the brightness of the first light at the first position is greater than the brightness of the second light at the second position. According to this configuration, the first light can provide sufficient light stimulus to others at the first position, making it easier for others to recognize the vehicle at an early stage. Also, glare to others at the second position can be reduced. This makes it easier for others outside the vehicle to recognize the vehicle while reducing glare to others.

[0071] (Configuration 4) The vehicle described in any one of configurations 1 to 3, wherein the cross-sectional area of ​​the first light at the first position is smaller than the cross-sectional area of ​​the second light at the second position. According to this configuration, the first light can cause others at the first position to perceive light for a short period of time, providing sufficient light stimulation to others and making it easier for others to recognize the vehicle from a distant location. Furthermore, even when the first position is set to a more distant location, others can easily recognize the vehicle. Furthermore, the second light can cause others to perceive light from a wide range of locations including the second position and its surroundings, making it easier for others to recognize the vehicle at an earlier timing than when the vehicle reaches the second position. Therefore, others outside the vehicle can more reliably recognize the vehicle from a distant location and can easily recognize the vehicle at an earlier timing when they are close to the vehicle. Furthermore, others who move from the first position to the second position can perceive both short-term light and long-term light, making it easier for others outside the vehicle to recognize the vehicle.

[0072] (Configuration 5) A vehicle described in any one of configurations 1 to 3, wherein the cross-sectional area of ​​the first light at the first position is larger than the cross-sectional area of ​​the second light at the second position. According to this configuration, the first light can be perceived by others in a wide range of positions, including the first position and its surroundings, making it easier for others to recognize the vehicle at an earlier timing than when the vehicle reaches the first position. Furthermore, the second light can be perceived by others in the second position as a short-duration light, providing sufficient optical stimulation to others and making it easier for others to recognize the vehicle more reliably. Therefore, others outside the vehicle can more easily recognize the vehicle at an earlier timing from distant positions and more reliably from positions close to the vehicle. Furthermore, it is possible to cause others who move from the first position to the second position to perceive both long-duration light and short-duration light, which also makes it easier for others outside the vehicle to recognize the vehicle.
