摘要： Light distribution characteristics are defined which define a correspondence relation between the position of a reflection point on a reference plane and the position of an image of a light source. In accordance with the light distribution characteristics, a path line in the reference plane is determined. A profile curve for each of a plurality of sampling points dispersibly distributed on the path line, is determined in accordance with the light distribution characteristics, the profile curve passing through the sampling point and corresponding to the topological shape of a reflecting surface to be determined. As the reflection point moves along the profile curve, the image of the light source moves in the direction crossing the reference plane in accordance with the light distribution characteristics. The topological shape of the reflecting surface is determined in accordance with the profile curve determined for each sampling point.

摘要： Whereas incandescent light bulbs and other similar light sources known in the related art emit light in all directions, LED lamps can emit light in a single direction, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. In accordance with an embodiment of the disclosed subject matter, an LED lamp for a light source of a headlamp can include an LED chip in the vicinity of the focus of a projection means and a shielding member covering a portion of the LED chip in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip is magnified and projected in an illumination direction by a projection lens or the like constituting the projection means. Accordingly, accurate light distribution characteristics can be obtained in a simple manner by projecting in the illumination direction using the projection lens.
