The lines 26 are electrically connected to each other. The control unit 16 has a control mechanism and a control circuit mechanically linked to the reflector so as to control the lighting of the ultraviolet lamp 10 in response to the operation switch 24 and the temperature sensor 17 and to open and close the reflector 15. .
The temperature sensor 17 is a temperature-sensitive element that is attached to the tube wall 11 of the ultraviolet lamp 10, detects the temperature of the tube wall, and outputs a signal corresponding to this to the control unit 16. The control unit 16 detects the temperature of the tube wall 11 of the ultraviolet lamp 10 by the temperature sensor 17, and when the temperature is not within the tube wall temperature range A where the maximum illuminance is obtained, the opening of the reflection plate 15 is closed. This is a control device that controls the opening of the reflector plate 15 to form the opening 18 when the temperature is within the predetermined tube wall temperature range A. Therefore, as will be seen later, when the reflector 15 shown in FIG. 1 is open, the object 19 is irradiated with the ultraviolet rays at the maximum illuminance.

けることができる。Referring to FIG. 6, when the operation switch 24 is turned on to turn on the ultraviolet lamp 10, the control unit 16 measures the ambient temperature by the temperature sensor 17 (step 101).
If the ambient temperature is lower than the maximum efficiency temperature range A, the control unit 16
Energizes the lamp 10 while keeping the opening of the reflector 15 shown in FIG. 2 closed (102). This is a temperature sensor
The output of 17 continues until it shows the temperature of the maximum illuminance range A of the ultraviolet lamp 10. In this state, the reflection plate 15 wraps the ultraviolet lamp 10, which promotes the temperature rise of the tube wall 11. The ultraviolet rays emitted from the tube 10 are condensed on the diffused reflection treated surface 15a of the closed reflector 15 and return to the tube wall 11. When the output of the sensor 17 indicates the tube wall temperature range A of maximum illuminance in step 101, the control unit 16 sets the reflector 15 to the open state shown in FIG. As a result, the object 19 can receive the ultraviolet rays with the maximum illuminance while being condensed by the elliptical irregular reflection processing surface 15a.
