- the road surface ahead in the turn direction is illuminated by the upper left irradiation range LH by the outer reflecting portion 47 on the right side in the vehicle width direction.
- the outer reflecting portion 47 may be provided on both the left and right light support portions 50 in the vehicle width direction, or on either the left or right side. Even when the outer reflecting portion 47 is provided on the left and right, the irradiation ranges LU and RU of the outer reflecting portion 47 are asymmetrical on the left and right sides, and the left and right irradiation ranges are made different according to the road regulations of left-hand traffic or right-hand traffic. Is possible. For example, when the road regulation is left-hand traffic, the irradiation range in front of the left side can be further expanded to the left side to improve the visibility of the road shoulder and the sidewalk.
- the high beam LED 60 that supplies irradiation light to the outer reflecting portion 47 is turned off.
- it can be set so that the light is turned on only when the roll angle exceeds a predetermined value.
- FIG. 12 is a perspective view of the light support portion 50 according to the second embodiment of the present invention.
- the present embodiment is characterized in that an inner reflection portion 100 is provided on the side wall 54 provided on the side portion of the high beam reflector 42 on the inner side in the vehicle width direction so as to reflect the irradiation light of the high beam LED 60 to the upper outside of the vehicle body.
- the outer reflecting portion 47 on the left side in the vehicle width direction irradiates the irradiation light of the high beam LED 60 upward on the left side of the vehicle body as compared with the reflected light reflected by the high beam reflectors 42 and 46 on the left side in the vehicle width direction.
- the outer reflecting portion 47 irradiates the light emitted from the high beam LED 60 upward on the right side of the vehicle body as compared with the reflected light reflected by the high beam reflectors 42 and 46 on the right side in the vehicle width direction. Thereby, the irradiation range of the high beam can be expanded upward.
- the number and type of light sources, the area and shape of the light emitting section, the location of the light source, the presence / absence of a projector lens, the number and shape of the high beam reflectors are not limited to the above-described embodiments, and various changes can be made. .
- the outer reflectors are provided on the left and right sides of the one light.
- the structure of the present invention can be obtained.
- the shape of the light emitting part may be a horizontally long rectangle, and the light source may be an incandescent bulb or the like.
- an outer reflection part and an inner reflection part may be provided in the vicinity of the low beam LED so that the irradiation range of the low beam LED is expanded upward.
- the headlamp device according to the present invention is not limited to a motorcycle, and can be applied to a straddle-type tricycle that balances the vehicle body by tilting the vehicle body during turning.
