Light projecting device and vehicular headlamp
A light-projecting device according to the present invention includes a plurality of light source units including (i) a light emitting section that emits light upon receiving a laser beam and (ii) a reflector. Each of the light source units project light to a corresponding one of light-projected spots which is a region to which light is projected in an illuminated region in a partitioning manner, and the illuminated region is formed by combining a plurality of the light-projected spot.
1. A light-projecting device, comprising:
a plurality of light source units each including (i) a light source and (ii) a light distribution section provided corresponding to the light source,
the plurality of light source units including a first light source unit illuminating a more distant place than another light source unit,
the first light source unit including, as the light source, a light emitting section which (i) contains fluorescent material that emits fluorescence upon receiving a laser beam and (ii) emits light at a brightness of not less than 200 cd/mm 2 ,
the first light source unit illuminating a part of an illuminated region illuminated by the light-projecting device,
the first light source unit (i) illuminating an object captured by a camera for capturing a range including the illuminated region and (ii) blinking light illuminating the object with a blink frequency of not less than 1 Hz and not more than 10 Hz.
2. The light-projecting device according to claim 1 , wherein the object is a pedestrian, a light vehicle, or a motorcycle.
3. The light-projecting device according to claim 1 , wherein the first light source unit raises the frequency with which to blink the light illuminating the object, as a distance between the light-projecting device and the object becomes shorter.
4. A vehicle headlamp, comprising the light-projecting device according to claim 1 .
