HYBRID LED/LASER LIGHT SOURCE FOR SMART HEADLIGHT APPLICATIONS
Apparatus including a hybrid light source for smart automotive-headlight applications. The hybrid light source includes: an LED light source of full-area illumination; a laser-pumped phosphor material that provides hot-spot illumination; a DMD having plurality of micromirrors coupled to receive light from the full-area illumination and the hot-spot illumination, wherein each micromirror selectively reflects light in one of a plurality of directions; and projection optics that receives light selectively reflected by the micromirrors and is configured to project the received light as a beam having a shaped illumination-intensity pattern. Another aspect includes an assembly including a heatsink; an LED on the heatsink that emits LED pump light; a first phosphor layer on the LED that absorbs LED pump light and outputs a full-area illumination having wavelength-converted light and an unconverted portion of LED pump light; and a laser-pumped second phosphor layer coupled to output wavelength-converted and laser light as hot-spot illumination.

Illuminating lamp for vehicle
When a pedestrian who is crossing a road or is about to cross a road is detected and it is determined that there is a risk of the own vehicle coming into contact with the pedestrian, a figure rendering forming optical unit provided in a housing of a head lamp emits a spot of light having a predetermined width and a predetermined length to a road surface ahead in a crossing direction including the pedestrian or the like. Accordingly, the pedestrian or the like knows the presence of an approaching vehicle and a driver knows the presence of the pedestrian or the like who is crossing a road or is about to cross a road.

VEHICLE INFRARED LAMP SYSTEM, VEHICLE INFRARED SENSOR SYSTEM, VEHICLE INFRARED-SENSOR-EQUIPPED LAMP, AND OPTICAL-SENSOR-EQUIPPED LAMP
A vehicle infrared lamp system mounted on a vehicle equipped with an infrared camera includes: an infrared light source; a rotating reflector; an other-vehicle position acquisition unit configured to acquire position information of another vehicle; and a control unit configured to control a lighting state of the infrared light source based on the position information of the other vehicle acquired by the other-vehicle position acquisition unit such that a dimming region where radiant intensity of infrared light is lower than radiant intensity of any other region is formed on at least a part of the other vehicle.
ILLUMINATION DEVICE AND VEHICLE LAMP
In an illumination device, an incidence angle of a laser beam, which is scanned by a laser beam scanning mechanism, with respect to a wavelength conversion member is set to an angle where the laser beam does not directly enter a projection lens when the wavelength conversion member is damaged, chipped or fallen off, and a laser light source and the laser beam scanning mechanism are located at a position corresponding to at least one of an upper side and a lower side of a light distribution pattern with respect to the wavelength conversion member, and are disposed to be deviated to either one of one side corresponding to a left side of the light distribution pattern and other side corresponding to a right side of the light distribution pattern.
