Title:
VEHICLE LIGHT AND VEHICLE LIGHT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/189289
Kind Code:
A1
Abstract:
A high-beam light unit (42H) includes: a rotating reflector (65) that rotates while reflecting visible light emitted from a visible light source (44) and infrared light emitted from an infrared light source (45), and horizontally scans visible light and infrared light on a virtual vertical screen disposed at a predetermined distance from a vehicle; and a photodiode (47) that receives infrared light emitted from the infrared light source (45) and reflected from a target object. A lamp control unit (43) sets the emission timing of infrared light from a first IR-LED and the emission timing of infrared light from a second IR-LED to be different from each other such that infrared light is not simultaneously emitted from the first IR-LED and the second IR-LED of the infrared light source (45).
