Abstract: Disclosed herein is an apparatus for generating a laser. The apparatus includes, on an upper surface of a PCB, a display unit (50) which displays a charge state and an intensity of laser, a switch unit (60) which control power, the intensity of the laser and the emission of the laser, a safety unit (80) which includes contact point parts, and a control unit (70). The apparatus includes, on a rear surface of the PCB, a reflector (10) which has first and second spaces, a xenon tube (12) which emits light, a crystal rod (11) which amplifies the light to generate a laser, a focusing lens (15) which focuses the laser and forms a focus, a focusing lens installation part (13), a capacitor (20) which applies voltage to the xenon tube, a drive unit (90) which charges the capacitor, and a battery (30) which supplies power to the drive unit.

Abstract: An apparatus for driving LEDs. The apparatus that drives a first LED unit having at least one LED and second LED unit connected to the first LED unit and having at least one LED comprises a rectifying unit for rectifying an AC power source connected to the first LED unit, a first current detector connected between the rectifying unit and the first LED unit and having its operation state changed depending on a level of current flowing through the first LED unit, a second current detector connected between the rectifying unit and the second LED unit and having its operation state changed depending on a level of current flowing through the second LED unit, and a reverse current protector connected between the first and second current detectors for providing a path to connect the first and second LED units in series.
