    摘要: To avoid the phenomenon of unsightly flickering in images projected by the projector, in high pressure discharge lamps—especially in high intensity discharge lamps, such as high pressure mercury lamps, metal halide lamps, and xenon lamps—that are used in projectors, even in the presence of the phenomenon of cyclical modulation of the lamp voltage by the returning the light spectrum when the light reflected by the dynamic color filter returns back through the optical system to the lamp, at least during steady operation of the discharge lamp (Ld), a target lamp current signal generation circuit (Up) acquires multiple lamp voltage detection signal (Sv) over a period that is at least as long as the color order cycle of the dynamic color filter (Of) and generates a target lamp current signal (St) based on the multiple lamp voltage detection signals (Sv) that were acquired.

The structure is such that the crystal resonator is arranged on one principal plane of the ceramic substrate, and the chip resistor and the temperature sensitive element are arranged on the other principal plane of the ceramic substrate, and the other principal plane of the ceramic substrate is positioned facing one principal plane of the circuit board, and heat conductive resin is interposed between the chip resistor and the circuit board. A surface mounted crystal oscillator of constant temperature type in which miniaturization is advanced, and the structure is simplified, is provided.

    摘要: In a power feeding apparatus, current flowing through the discharge lamp is controlled not to exceed a current limit value. Until the discharge status changes to the arc discharge, the current limit value is a first current limit value, and after that, the current limit value changes to the second current limit value. The first current limit value is 70% of the second current limit value or less, and further, for 0.2 ms or greater, the first current limit value is maintained after the discharge status changes to the arc discharge.
