摘要： In a discharge lamp lighting circuit, a DC—DC converting circuit has a switching element to be connected to a transformer and a primary winding thereof, and control is carried out in such a manner that the transformer stores energy while the switching element is set in an ON state in response to a signal sent from a control circuit, the energy is output from a secondary winding of the transformer while the switching element is set in an OFF state, and the switching element is turned ON when the energy is completely output from the secondary winding in a stable lighting state of a discharge lamp. A fluctuation is applied to the control of an output current or power related to the discharge lamp which is carried out for the ON period of the switching element, thereby changing a switching frequency.

摘要： In a lighting circuit 1A, there are provided a DC power circuit 3′ for outputting DC voltages having positive and negative polarities and a DC-AC converting circuit 4A for converting the output voltages into AC voltages through a plurality of switching elements and for then supplying the AC voltages to a plurality of discharge lamps 6—1 and 6—2. In the case in which each discharge lamp is to be lighted up, a polarity fixing period is set to define the polarity of the voltage to be supplied from the DC-AC converting circuit 3′ to the discharge lamp before and after the discharge lamp is lighted up to be positive or negative. For this period, control is carried out such that a current flowing to the discharge lamp does not exceed a predetermined limit current value. Consequently, when a first discharge lamp has already been lighted up and a second discharge lamp is to be lighted up, it is possible to relieve the influence of a thermal stress applied to the first discharge lamp by the control of an output polarity for the discharge lamp.

摘要： A discharge lamp lighting circuit 1 has a DC power supply circuit 3 for outputting a DC voltage, a DC-AC conversion circuit 4 for converting the output voltage of the DC power supply circuit into an AC voltage and then supplying the AC voltage to a discharge lamp 6, and a current detection circuit 8 for detecting an electric current flowing into the discharge lamp. Just after the discharge lamp 6 is lighted, the output frequency of the DC-AC conversion circuit 4 is temporarily changed for defining the lighting frequency of the discharge lamp as a low frequency, to perform DC lighting over a predetermined time. A control circuit 7 determines the duration of the DC lighting by the time it takes for the product of the time and the value of current flowing into the discharge lamp 6 to equal a predetermined value.
