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 5):
A vehicle lighting apparatus comprising:\n said optical source unit as set forth in  claim 4 ; a projection optical unit for receiving said output light beams of said optical source unit to project said output light beams; and a control unit for controlling said optical source unit, when said first optical sources are determined to be all normal in accordance with first output signals of said first detectors, respectively, said control unit being adapted to drive all of said first optical sources, so that each of said output light beams of said optical source unit has a predetermined light flux, when at least one of said first optical sources is determined to be abnormal and said second optical source is determined to be normal in accordance with the first and second output signals of said first and second detectors, respectively, said control unit being adapted to turn off said at least one of said first optical sources, to drive said second optical source unit, and to operate said variable polarization elements of said light beam combining and splitting elements, so that the output light beam of at least one of said light beam combining and splitting sections corresponding to said at least one of said first optical sources has said predetermined light flux.
