    摘要： A discharge lamp lighting circuit includes a power supplying portion having a series resonant circuit including transistors and a bridge driver, a starting portion for applying a high voltage pulse to a discharge lamp to promote a lighting operation, a lighting confirming portion for generating a lighting confirmation signal Sf indicating that a lighting operation for the discharge lamp fails or is successful by the high voltage pulse, and a control portion for generating a control signal Sc to control a driving frequency of the bridge driver. The lighting confirming portion generates a lighting confirmation signal Sf based on a relationship of the magnitude between a lamp voltage equivalent signal VS and a predetermined voltage V4 at a time that a predetermined time Δt passes since the application of the high voltage pulse to the discharge lamp.

    摘要： A discharge lamp lighting circuit 1 is provided with a DC-AC conversion circuit 3 having a plurality of switching elements 5H, 5L and a series resonance circuit (8, 9, 7p), and control means 17 for preventing a situation in which the drive frequency of the switching element remains less than its specified minimum frequency. When the discharge lamp is lit, driving control of the switching element is carried out in a frequency range higher than the series resonance frequency. By using a driving situation detection circuit 15, a driving situation of the switching element is monitored based on a relation with a phase of a lamp current which flows through the discharge lamp. If the drive frequency of the switching element becomes less than the specified minimum frequency, the drive frequency is increased, and thereby, a lower limit of the drive frequency is automatically restricted.

    摘要： In a lighting apparatus for an illumination light source (discharge lamp or the like), a fly-back type DC-DC converter circuit comprises a transformer and a switching element. A control circuit is provided for controlling power supplied to the illumination light source, such that operation is controlled in a current boundary mode by a control signal sent from the control circuit to the switching element. A fluctuation generator circuit is provided for giving fluctuations to a frequency at which the switching element is driven by changing the power supplied to the illumination light source with reference to a target power value associated with the power control for the illumination light source.
