Lighting device for vehicle

摘要

For light irradiation transversely inclined with respect to the front of a vehicle lighting device that reflects light from a plurality of semiconductor light emitting devices toward the forward part of the lighting device via reflector, a structure is provided in which lights emitted from five semiconductor light emitting devices are reflected toward the forward part of a lighting device via reflector. A reflecting surface of the reflector is a parabolic cylindrical curved surface having a focal line extended horizontally. The five semiconductor light emitting devices are on the focal line at an interval. Each of the directions of the emitted lights is varied for each semiconductor light emitting device with respect to the focal line direction. Consequently, the light emitted from each of the semiconductor light emitting devices is not diffused vertically but only horizontally, thereby forming five oblong light distribution patterns in positions shifted from each other horizontally.
