Ultraviolet light detection device
First Claim
1. An ultraviolet light detection device for detecting ultraviolet light radiated to an occupant of a vehicle, the device comprising:
- a detecting element including an ultraviolet detector for detecting intensity of ultraviolet light radiated inside of the vehicle, wherein the ultraviolet detector is made of lanthanum-doped lead zirconate titanate (PLZT); and
an electrical unit for outputting an ultraviolet light detection signal representing that a predetermined or more amount of ultraviolet light is radiated to the occupant, whereinthe ultraviolet detector sends ultrasonic wave to an incidence direction of ultraviolet light, and detects ultrasonic wave reflected by an object to be detected, andthe electrical unit outputs the ultraviolet light detection signal when the detecting element detects the predetermined or more amount of ultraviolet light and when the object is determined to be the occupant of the vehicle based on the reflected ultrasonic wave.

Abstract
A detector made of lanthanum-doped lead zirconate titanate detects intensity of ultraviolet light radiated inside of a vehicle. The detector sends ultrasonic wave to an incidence direction of ultraviolet light, and detects ultrasonic wave reflected by an object. An electrical unit determines the object to be an occupant of the vehicle or not based on the reflected ultrasonic wave. The electrical unit outputs a signal representing that a predetermined or more amount of ultraviolet light is radiated to the occupant, when the detector detects the predetermined or more amount of ultraviolet light and when the electrical unit determines the object to be the occupant.
