ABSTRACT:
The light distribution pattern for a vehicle having a predetermined horizontal cut-off line section at the top portion on one side of the vertical central line and an oblique cut-off line section whose central line side is lowered in another side. The light distribution pattern of the light source is formed by arranging a plurality of semiconductor light emitting devices with a configuration almost the same shape as the light distribution pattern for a vehicle. The semiconductor light emitting device has a luminance surface whose configuration is almost the same shape as the light distribution pattern for a vehicle. Further, the light source comprising the semiconductor light emitting device includes a fluorescent material whose excitation source is the emission from the nitride semiconductor device and a part of region of the fluorescent material emits light with higher luminance or higher color rendering properties compared with the other regions.
