The control unit 16 controls the lighting of the ultraviolet lamp 10 in response to the operation switch 24 and the temperature sensor 17, and has a control mechanism and a control circuit mechanically linked to the reflector 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 the temperature to the control unit 16. The control unit 16 detects the temperature of the tube wall 11 of the ultraviolet lamp 10 with 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 reflector 15 is closed. When the temperature is within a predetermined tube wall temperature range A, the control device controls the opening of the reflection plate 15 to form the opening 18. Therefore, as will be understood later, the object 19 is irradiated with ultraviolet rays at the maximum illuminance when the reflector 15 shown in FIG. 1 is opened.

けることができる。Referring to FIG. 6, when operation switch 24 is turned on to turn on ultraviolet lamp 10, control unit 16 measures ambient temperature by temperature sensor 17 (step 101).
If the ambient temperature is lower than the maximum efficiency temperature range A, the controller 16
Power is supplied to the lamp 10 while the opening of the reflector 15 shown in FIG. 2 is kept closed (102). This is a temperature sensor
The output of 17 continues until it indicates the temperature of the maximum illuminance range A of the ultraviolet lamp 10. In this state, the reflecting plate 15 wraps the ultraviolet lamp 10, thereby promoting the temperature rise of the tube wall 11. Ultraviolet rays emitted from the tube 10 are condensed on the irregular reflection processing surface 15a of the closed reflector 15, and return to the tube wall 11. When the output of the sensor 17 indicates the maximum illuminance tube wall temperature range A in step 101, the controller 16 sets the reflector 15 to the open state shown in FIG. 1 (103). Thereby, the object 19 can receive the ultraviolet rays with the maximum illuminance and condensed on the elliptical irregular reflection processing surface 15a.

When the ambient temperature when the operation switch 24 is turned on is within the maximum efficiency temperature range A, the control unit 16 opens the opening 18 of the reflection plate 15 as shown in FIG. The unit enters the standby state 104 in preparation for supplying power to the power supply 10. afterwards,
When the present apparatus is applied to, for example, a printer, when a print instruction is given, the control unit 16 responds to this and actually energizes the lamp 10. In any case, in the open state of the reflecting plate 15 in which the opening 18 is formed, the ultraviolet light emitted from the tube 10 is reflected by the elliptical reflecting surface 15a,
