Title:
LIGHT IRRADIATION DEVICE, RESIN CURING DEVICE PROVIDED WITH SAME, ULTRAVIOLET STERILIZATION DEVICE, AND PHOTOTHERAPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/203728
Kind Code:
A1
Abstract:
In a light irradiation device (5), a light emission control unit (19) sets, as a light emission stop signal timing, the time when the output result of a light measurement unit (16) has exceeded a threshold value set by a comparison unit (17). In other words, when a main capacitor (13) is being charged at a prescribed voltage, the light emission control unit (19) stores an adjusted threshold value in which the threshold value is adjusted to conform to the individual difference of the light measurement unit (16) such that the light emission stop signal is outputted at the timing at which the amount of light emitted by a flash discharge tube (10) is an appropriate light amount. Furthermore, when the main capacitor (13) is charged at an operating voltage differing from the prescribed voltage, a threshold-value corrected value according to the operating voltage and the adjustment threshold value is calculated. The calculated threshold-value corrected value is set in the comparison unit as the threshold value. It is thereby possible to control the light emission stop timing of the flash discharge tube (10) in correspondence with various power source voltages.
