摘要： A lighting apparatus for a high-pressure discharge lamp that has an electric discharge container made of quartz glass, and containing a pair of counter electrodes and a power supply unit that supplies AC current to the high-pressure discharge lamp. The power supply unit has a stationary power lighting mode and a modulated power lighting mode that supplies current having power less than power in the stationary power lighting mode. The modulated power lighting mode supplies a rectangular AC current having a first term and a second term. A mean high-frequency current value supplied to a first electrode is greater than a mean current value supplied to a second electrode in the first term. A current is supplied to the second electrode for a term longer than the half-cycle period in the second term, the current being lower than the mean high-frequency current value supplied to the first electrode.

摘要： A low cost DC-DC converter facilitates a reduction of the switching loss in the wide, variable range of the continuity ratio for a main switching device. The DC-DC converter includes a direct current source, an ON-OFF-controllable main switching device, a main coil which is series connected to the main switching device, a fly-wheel diode which is arranged such that the induction current of the main coil flows when the main switching device is shifted into the OFF state, and a smoothing capacitor for smoothing the output of the main coil, Also included is an auxiliary transformer with a primary winding as a direct current source and a secondary winding. The main switching device and the auxiliary switching device are controlled such that they are shifted alternatively into the ON state, and the main switching device, is shifted into the ON state a given time after the auxiliary switching device has been shifted into the OFF state.

摘要： The purpose of the present invention is to make it possible to output stable light by optimizing the wavelength conversion efficiency in a wavelength conversion element without employing an optical detection device such as a photo diode in a laser light source device. A fundamental light wave emitted from a semiconductor laser (2) is wavelength converted by a wavelength conversion element (5) and is emitted therefrom. A lighting circuit (20) supplies electric power for the aforementioned semiconductor laser (2) to turn on the semiconductor laser (2). A control unit (21) controls the operation of the device while controlling the amount of power supplied to a heater means (7) such that the wavelength conversion element (5) reaches a temperature at which optimum wavelength conversion efficiency is acquired. The temperature detected by a temperature detection means (Th1) is input to the control unit (21), and the control unit (21) defines the temperature of the wavelength conversion element (5) at which the maximum amount of power is supplied to the heater means (7) as a set temperature at which the optimum wavelength conversion efficiency is acquired, and performs feedback control of the temperature of the wavelength conversion element (5) so that the temperature of the wavelength conversion element (5) reaches the aforementioned set temperature by controlling the amount of heat supplied from the heater means (7).
