In order to achieve the above objective, an embodiment of the present invention provides a headlight structure for a motorcycle including: a lens; a light source module including a first light source and a second light source, which emits a light in a plurality of directions; a headlight housing supporting the lens from a rear side of the motorcycle; a socket member arranged on the headlight housing to supply a power source to the light source module; and a reflector arranged in the upper or lower side of the second light source at the area overlapping the second light source when viewed from the above: wherein the first light source is located and directed in a forward direction of the motorcycle along an axial direction of an optical axis, wherein the second light source is located and directed to a vertical direction to the axial direction of the optical axis, and arranged in the area overlapping the socket member when viewed from the above or at a rear position of the socket member, and wherein the reflector is arranged in the area overlapping the socket member when viewed from the above.
According to the embodiment of the present embodiment, since the second light source is arranged in the area overlapping the socket member when viewed from the above or at a rear position of the socket member, and the reflector is arranged in the area overlapping the socket member when viewed from the above, the front end of the reflector is able to be arranged at a further rear position.
Therefore, since it is possible to shorten the distance between the socket member and the front end of the reflector, the embodiment of the headlight structure is made compact. Moreover, since the embodiment of the headlight structure is made compact, it is possible to enlarge the space where electric parts are accommodated in the motorcycle body.
In the headlight structure of the embodiment of the present invention, the first light source is arranged on a side wall which is provided on the headlight housing, wherein the second light source is arranged on a mounting wall w hich is provided on the upper or lower side of the side wall, and wherein in the case that the mounting wall is provided in the upper side of the side wall, the socket member forming area is formed on the rear side relative to an extension line of the side wall and on the upper side relative to an extension line of the mounting wall when viewed from the side, and in the case that the mounting wall is provided in the lower side of the side wall, the socket member forming area is formed on the rear side relative to an extension line of the side wall and on the lower side relative to an extension line of the mounting wall when viewed from the side.
According to the embodiment of the present invention, since the socket member is arranged in the socket member forming area, it is possible to avoid the generation of the dead space, effectively to use the space in the headlight, and to make the headlight compact.
In the headlight structure of the embodiment of the present invention, the mounting wall is arranged below the socket member, the second light source emits a light in a downward direction, and wherein a reflector is arranged below the second light source, the reflector is arranged in an area overlapping the socket member when viewed from the above. According to the embodiment of the present invention, since the second light source emits a light in a downward direction, and the reflector is arranged below the second light source, the reflector is able to be arranged in an area overlapping the socket member when viewed from the side. Therefore, it is possible to make the headlight structure more compact.
In the headlight structure of the embodiment of the present invention, a projector lens is arranged in front of the light source module and is supported by an extension member which extends from the headlight housing, and wherein the extension member extends from the headlight housing to a position forward of the second light source and lower than the second light source.
The light from the second light source is emitted to the reflector, is reflected by the reflector, and is emitted in the front direction. According to the embodiment of the present invention, since the extension member extends from the headlight housing to a position forward of the second light source and lower than the second light source, it is possible to avoid directly projecting the light from the second light source on the eye of the viewer in a front of the motorcycle.
In the headlight structure of the embodiment of the present invention, the second light source is formed by LED, and the mounting wall is LED substrate which is separate from the headlight housing.
According to the embodiment o the present invention, since the mounting wall is LED substrate which is separate from the headlight housing, it is possible to design the layout of the second light souse flexibly regardless of the shape of the headlight housing.
In the headlight structure of the embodiment of the present invention, a coupler for power supply which fits in the socket member is arranged in the socket member forming area.
According to the embodiment of the present invention, since a coupler for power supply is arranged in the socket member forming area, it is possible to accommodate the coupler for power supply in the socket member forming area effectively, and to make the headlight further more compact.
