OPTICAL SCANNING DEVICE |
(57) There is provided a headlight unit 1 configured to make phosphors emit light efficiently.
The headlight unit 1 includes a laser-light emission device 14, a light deflector
15, a phosphor panel 20, and a projector lenses 19 in order along a light traveling
path. The rotational position of a light emitting unit 45 of the laser-light emission
device 14 about an optical axis is so set that the minor axis direction of an optical
spot Sp generated on a light incident surface 41 of the phosphor panel 20 will be
a direction along a scanning direction Hc of the optical spot Sp on the light incident
surface 41.
