HAIR-REMOVAL DEVICE AND METHOD OF USING ONE SUCH DEVICE

摘要

The invention relates to a hair-removal device which is intended for local skin application. The inventive device is designed to emit at least one light pulse which is generated by an electric current impulse that passes through a flash lamp (LF) such as to form an electric arc, said current originating from the discharge of a capacitor (CE) and being controlled by a fast-switching electronic switch (SW). According to the invention, the aforementioned three elements are disposed in a main loop (CE-SW-LF). During each capacitor discharge, the current passing through the lamp generates a measurement signal (URm) which is representative of said current and which is compared to a reference value (Uref) by a hysteresis comparison device (COMP), in order to control the open or closed state of the switch and to adjust the current by means of the high-frequency cut-off thereof around a determined intensity (Icritic) throughout essentially the entire duration of the current impulse.
