摘要： There is provided a lamp comprising a light source, a horizontal double ellipsoidal reflector composed of two reflecting surface units joined horizontally in opposing relation to each other and each formed from a spheroid, and aspheric lenses. Each of the two reflecting surface units is formed by cutting, radially around the center axis of the light source, a portion from the spheroid having a first focal point located on the center axis and adjacent the light source and a second focal point located on a line passing through the first focal point and tilted appropriately from the light-source center axis such that the cut portion spans, around the center axis, a range of 5.degree. to 9.degree. in either vertical direction from a horizontal line. The aspheric lenses are provided horizontally to correspond to the respective second focal points of the reflecting surface units of the ellipsoidal reflector and converge reflected light beams from the respective reflecting surface units. It is also possible to provide a horizontal triple ellipsoidal reflector further comprising a central reflecting surface unit formed from a spheroid and located at the center portion thereof in addition to the two reflecting surface units each formed of a cut portion spanning a range of 5.degree. to 6.degree. around the center axis.

摘要： A lamp including a light source, a petaline reflector, and aspheric lenses. The petaline reflector is formed of a plurality of reflecting surface units combined radially around the center axis of the light source. Each of the reflecting surface units is obtained by cutting, radially around the center axis, a portion from a spheroid having a first focal point located on the center axis and adjacent the light source and a second focal point located on a line passing through the first focal point and tilted appropriately from the center axis such that the cut portion spans a range of 15.degree. to 60.degree. around the center axis. The aspheric lenses are disposed to correspond to the respective second focal points of the reflecting surface units of the petaline reflector and converge reflected light beams from the respective reflecting surface units. Shades for forming a light distribution pattern are disposed at the respective near-focal points of the aspheric lenses.

摘要： There is provided a lamp composed of a light source, a tilted ellipsoidal rotation surface reflector, and an annular cylindrical lens. The tilted ellipsoidal rotation surface reflector is formed of an ellipsoidal rotation surface emerging when an ellipsoid, having a first focal line located on the center axis of the light source and adjacent the light source and a second focal point located on an oblique line passing through the first focal point and tilted appropriately from the light-source center axis and assumed on a plane containing the light-source center axis and the oblique line, is rotated around the light-source center axis. The annular cylindrical lens is obtained by rotating, around the light-source center axis, the cross-sectional configuration of an aspheric lens having a focal point adjacent the second focal point of the ellipsoid and having an optical axis nearly parallel to the light-source center axis.

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.
