PROBLEM TO BE SOLVED: To provide a switching power source circuit capable of emitting treatment light energy of a desired amount for light-based dermatological treatment device.SOLUTION: A switching power source drives a flash lamp 112 of dermatological treatment equipment to discharge a relatively small light pulse sequence positioned to a specific point in a waveform of an AC radiation source. The power source can not only supply aggregate light energy sufficient to therapeutically heat a target chromophoric group in a skin area without giving any undesirable damage to surrounding tissues, but also provide an additional advantage that it is virtually not necessary to acquire corresponding electrical energy from a charged capacitor. Further, the power source corrects the operation based on a predetermined value indicating aging/efficiency characteristics of the flash lamp so as to correct the performance deterioration of the lamp in the service life of the flash lamp. |
