Abstract:
An optical source unit includes a first optical source for emitting a P-polarized light beam, a first detector for detecting whether the first optical source is normal or abnormal, a second optical source for emitting an S-polarized light beam, a second detector for detecting whether the second optical source is normal or abnormal, and a light beam combining section including a polarization beam splitter for transmitting the P-polarized light beam and reflecting the S-polarized light beam to combine the P-polarized light beam and the S-polarized light beam into an output light beam of the optical source unit.

Claim (Index 8):
A vehicle lighting apparatus comprising:\n said optical source unit as set forth in  claim 7 ; a projection optical unit for receiving said output light beams of said optical source unit to project the output light beams; and a control unit for controlling said optical source unit, when said first and second optical sources are determined to be both normal in accordance with first output signals of said first and second detectors, respectively, said control unit being adapted to drive said first or second optical source and said first or second variable polarization elements, so that said S-polarized component output from said first or second variable polarization element has said predetermined light flux, when one of said first and second optical sources is determined to be normal and the other of said first and second optical sources is determined to be abnormal in accordance with the first and second output signals of said first and second detectors, respectively, said control unit being adapted to drive said one of said first and second optical sources, and to operate said first or second variable polarization elements of said light beam splitting sections or said light beam combining and splitting sections, so that the output light beams of said light beam combining and splitting sections have said predetermined light flux.
