- the capacitor voltage decreases as the discharge proceeds, the current flowing through the discharge lamp 18 and the lamp voltage are large at the beginning of irradiation within one irradiation period. It decreases with time and decreases sharply at the end of irradiation. Therefore, the amount of light emitted from the discharge lamp 18 also largely decreases with the passage of time at the beginning of irradiation, and sharply decreases at the end of irradiation.
- the lamp voltage decreases over time as indicated by the envelope a f. Therefore, the light emission amount differs between the initial stage and the final stage of the irradiation. As a result, a constant heating value cannot be continuously applied to the skin, and the heating value is too low at the end of irradiation, and the beauty effect is reduced.

- the voltage between the collector and the emitter of the current control element 34 becomes a very small voltage, and the function of the element 34 is saturated, so that it functions as a switch element.
- the discharge lamp 18 is energized with a current corresponding to the capacitor voltage lower than the current in the constant current control. This The ramp voltage decreases substantially as shown by the envelope cd according to the capacitor voltage.
- the points b, c, and d have been described as voltages. However, when the lamp voltage increases, the current also increases. Also, as shown by points d and ⁇ , the voltage drop at point ⁇ is larger than that at one irradiation period because the energization indicated by the envelope af is controlled by the control indicated by the envelope bc. This is because the conduction current in the early stage of irradiation is larger than that in the irradiation, and the discharge amount within one irradiation period is larger in the case of conduction indicated by the envelope af.
- the range enclosed by points a, b, and c indicates the amount of load applied to the current control element 34.
- This load amount is obtained by adding the current value corresponding to the voltage at point b and the pulse energizing time to the value obtained by subtracting the voltage at point b from the ac envelope value for each pulse between times T0 and T1. It is required by doing.

- the light emission amount it is not necessary that the light emission amount be completely the same until the end, and even if the light emission amount decreases a little at the end of irradiation, it may not affect the beauty effect.
- control is performed such that the discharge lamp 18 is supplied with a current corresponding to a capacitor voltage lower than the current in the constant current control at the end of irradiation. This reduces the capacitor voltage at time T0.
- the amount of load applied to the current control element 34 is reduced, and the amount of light emission suitable for beauty can be obtained while reducing the risk of the current control element 34 breaking down. If the point c is closer to the point b, the voltage at the point a can be reduced, and the area surrounded by the points a, b, and c is reduced, and the voltage applied to the current control element 34 is reduced. The load decreases.
- the point c is determined in consideration of the balance between the amount of load applied to the current control element 34 and the amount of light emission required for the operation, and the time T1 is determined.

Therefore, the power supply unit 30 cannot supply sufficient power to catch the lamp voltage and the current drop during one irradiation period. Therefore, after the end of the irradiation, when the current control unit 56 sets the power supply to OPT and the power supply to the discharge lamp 18 is stopped, the power supply unit 30 keeps the capacitor 2 until the current set charging voltage is reached. Charge 8.

Since a direct current is discharged, a semiconductor relay is an excellent switch type. Further, while the capacitor 28 is discharging through the load resistor 82, a signal for controlling the discharge lamp 18 not to emit light is output to the light emission instruction unit 70. As a result, the button 2 of the operation handle 16 connected to the light emission indicator 70 Even if 2 is pressed, discharge lamp 18 does not emit light. When the charging voltage becomes lower than the point g, the control signal for stopping the light emission is released, and the light is emitted when the button 22 of the operation handle 16 is pressed.
- the maximum capacitor setting voltage applied to the capacitor 28 based on the light emission amount input to the light output setting input unit 58 is If the capacitor voltage is higher than the maximum capacitor setting voltage, the capacitor voltage is made lower than the maximum capacitor setting voltage, so that the load on the current control element 34 is reduced to prevent element damage.

- the light emission is performed instantaneously, so that the time for energizing the current control element 34 is extremely short.
- the maximum rating which is generally published, is the maximum collector loss when current is continuously applied. Therefore, it differs from the instantaneous collector loss in the case of instantaneous energization. Since the instantaneous collector loss differs for each use case, the instantaneous collector loss was obtained from an experiment using an actually used circuit of the device, and an allowable value up to the destruction was obtained as an approximate value from the experiment. As a result, for the sample IGBT, it was confirmed that an instantaneous load about 10 times the published maximum collector loss may be acceptable.
- an element whose published maximum collector loss is about 10 times the maximum load capacity that can act on the current control element 34 can be used. Costs can be reduced. It has also been confirmed that the practically acceptable load when two current control elements 34 are connected in parallel is about twice as large as that with one current control element 34. Therefore, a plurality of current control elements 34 may be used in parallel.
- the connecting wires may be short-circuited in some cases. Also, the discharge load system may be short-circuited for some reason. In this case, since the lamp voltage applied to the discharge lamp 18 drops abnormally, if this voltage drop is detected, the presence or absence of a short circuit phenomenon in the discharge load system can be known.

- the drive output control switch 52 is controlled so that the current control element 34 does not operate even if either of the two is abnormal.
- the discharge lamp 18 has a limited life, and the current value and the amount of light emitted gradually change with use. Therefore, periodic replacement is required. Furthermore, the discharge characteristics of the discharge lamp 18 vary from product to product, and when the same voltage is applied without constant current control, the injected current varies, causing a difference in the amount of light emission and a difference in the heating value. Sometimes. Therefore, when the same subject undergoes a procedure after changing lamps, the settings used last time cannot be used as they are, and the settings need to be changed, which is troublesome. .

- the last period of the irradiation from time T1 to ⁇ 2 has minute differences due to variations in the discharge lamp 18 and changes in the characteristics during use, but is sufficiently shorter than the period of constant current control. Even with such control, the cosmetic heating effect as a whole does not substantially change in the treatment.
- the amount of light emitted from each pulse during the period of constant current control is the same, and the heating value at the beginning and end of irradiation is almost the same, so that light of intensity that is suitable for beauty is stabilized throughout one irradiation period. Irradiation is possible.
