That is, the operation may be repeated when the first set time elapses after the ultraviolet LEDs 510 and 520 are turned on, and turned on when the second set time elapses after the ultraviolet LEDs 510 and 520 are turned off. For example, when the ultraviolet LEDs 510 and 520 are turned on, they are turned off after 30 minutes, and when they are turned off, they are turned on when the ultraviolet LEDs 510 and 520 are turned off. As described above, it is needless to say that the ON / OFF control of the ultraviolet LEDs 510 and 520 can be variously set in the time setting.

That is, when the counted time corresponds to the set time, the time counting unit 1110 continuously generates an operation control signal and transmits the operation control signal to the operation control unit 1120. If the counted time does not correspond to the set time The operation control signal is not generated.

The operation control unit 1120 receives the operation control signal from the time count unit and operates the ultraviolet LEDs 510 and 520 when the counted time corresponds to the set time. That is, when the counted time corresponds to the set time, the operation control unit 1120 continuously receives the operation control signal from the time count unit 1110 to operate the ultraviolet LEDs 510 and 520, The time counting unit 1110 does not receive the operation control signal, and the ultraviolet LEDs 510 and 520 can not be operated.
