Title:
Lighting device
Document Type and Number:
Japanese Patent JP6314326
Kind Code:
B2
Abstract:
An illumination device that realizes a clear adaptive driving beam is provided. This illumination device includes: a light source that generates laser light; a movable mirror that has a mirror surface reflecting the laser light and is capable of driving the mirror surface; and a phosphor that is irradiated with the laser light reflected by the movable mirror and converts the laser light into fluorescence. In the laser light with which the phosphor is irradiated, a rise of an intensity distribution in a scanning direction of the phosphor is steeper than a rise of an intensity distribution in a vertical direction substantially perpendicular to the scanning direction.
