    • A power supply comprising a chopper circuit with an inductive filter element may drive a flashlamp to direct flashlamp radiation to a patient's skin. The waveform may have a generally constant current value and may be substantially independent of pulse width repetition rate and of pulse repetition rate. The flashlamp may be selected according to the type of treatment and the expected width of the treatment area. The wavelength of the radiation to be directed to a patient may be limited to a shallow tissue-penetrating, strongly melanin-absorbing wavelength spectrum, such as at most about 590 to 850 nm or at most about 590 to 700 nm. The chosen wavelength spectrum may be within the UVA through UVB wavelength spectrum so to cause localized pigmentation in a patient's skin. The chosen wavelength spectrum may be a continuous wavelength spectrum. A handpiece may have a housing comprising a housing interior with the flashlamp so that light from the flashlamp passes through the housing interior and out of an aperture for dermatological treatment of a patient. The flashlamp arc length is preferably about 20% greater than the aperture length.
    • 包括具有感应滤波器元件的斩波电路的电源可以驱动闪光灯以将闪光灯辐射引导到患者的皮肤。 波形可以具有大致恒定的电流值,并且可以基本上与脉冲宽度重复率和脉冲重复率无关。 可以根据治疗类型和治疗区域的预期宽度来选择闪光灯。 要引导到患者的辐射的波长可以限于浅层组织穿透,强烈黑色素吸收波长光谱,例如至多约590至850nm或至多约590至700nm。 所选择的波长光谱可以在UVA至UVB波长谱内,从而在患者皮肤中引起局部色素沉着。 所选择的波长光谱可以是连续波长谱。 手持件可以具有壳体,其包括具有闪光灯的壳体内部,使得来自闪光灯的光穿过壳体内部并且从用于患者的皮肤病学处理的孔中出来。 闪光灯弧长优选比孔径长度大约20%。
