  • Cosmetic treatment apparatus
    Patent number: 7491222
    Abstract: A cosmetic treatment apparatus comprises a discharge lamp, a capacitor, and a current controller. The capacitor supplies an electric current for the discharge lamp. The current controller controls the electric current flowing from the capacitor to the discharge lamp. In a first stage of the cosmetic treatment, the current controller performs a constant current control operation. In this operation, the current flowing to the lamp does not vary with variations of the capacitor voltage. In the end stage of the treatment, the current is lower, and it decreases with the capacitor voltage.
