Claims

[Scope of utility model registration request]

Six reflecting mirrors each having the same vertical width of the aperture, a light source disposed within each reflecting mirror, and a lens disposed to cover the front surfaces of these reflecting mirrors and the light source and equipped with a light control element. Each of the irradiation sets consisting of the reflecting mirrors, light sources, and lenses has type A light distribution characteristics, in which the upper edge of some of the irradiation sets is substantially in contact with the horizontal line in front of the vehicle and diffuses wide-area irradiation that spreads in the left and right directions. Another type has Type B light distribution characteristics, which mainly illuminates the area near the intersection of the horizontal line and vertical line in front of the vehicle, excluding the area above the horizontal line on the opposite lane side, and the remaining type has a type B light distribution characteristic that illuminates the area near the intersection of the horizontal line and the vertical line in front of the vehicle, excluding the area above the horizontal line on the opposite lane side. It has a type C light distribution characteristic that mainly irradiates the intersection of the vertical line and the vertical line, and a predetermined light distribution is achieved by appropriately combining and irradiating irradiation sets having the light distribution characteristics of types A, B, and C. A vehicle headlamp device characterized in that it obtains.
