Abstract
Provided is an ultraviolet light radiating device that can be operated after a short time even if placed in an environment in which stop time continues over an extended period of time. The ultraviolet light radiating device includes: an excimer lamp that emits ultraviolet light; a lighting circuit that applies a lighting voltage to the excimer lamp; and a controller that performs energization control for the lighting circuit. The controller performs control to energize the lighting circuit for a first predetermined time at a predetermined timing.
Claims11
An ultraviolet light radiating device comprising:
- an excimer lamp that emits ultraviolet light;
- a lighting circuit that applies a lighting voltage to the excimer lamp;
- and
- a controller that performs energization control for the lighting circuit,
- the controller performing control to energize the lighting circuit for a first predetermined time at a predetermined timing.
A method for using an ultraviolet light radiating device including an excimer lamp that emits ultraviolet light and a lighting circuit that applies a lighting voltage to the excimer lamp, the method comprising:
- a step (a) of executing a lighting mode of continuously energizing the lighting circuit to maintain a lighting state of the excimer lamp;
- and
- a step (b) of executing a standby mode of stopping energization to the lighting circuit and waiting for transition to the lighting mode,
- wherein the step (b) includes a step (c) of energizing the lighting circuit for a time within five minutes to perform auxiliary lighting when a predetermined time elapses after the transition from the lighting mode to the standby mode.
