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.

摘要： A discharge lamp lighting circuit is capable of preventing the discharge lamp from going out unexpectedly. The discharge lamp lighting circuit includes a DC-AC inverter which receives a power source voltage, boosts and converts the power source voltage into AC and supplies AC electric power to the discharge lamp 21. A control circuit sends a long cycle signal when the discharge lamp 21 is started. The cycle of the long cycle signal is longer than a frequency at the time of steady lighting. The control circuit sends a steady drive signal, which is a frequency at the time of steady lighting, to the DC-AC inverter 25. A cycle of the long cycle signal is set according to at least one of the power source voltage, the temperature of the discharge lamp lighting circuit or the extinguishing time.

摘要： A noise suppressor is disclosed in which a noise signal is detected by a first detector, then processed by an adaptive filter, and an output signal from the adaptive filter and an audio signal from audio equipment are added by an adder and reproduced by a speaker. The sound signal thus reproduced by the speaker and the noise signal are detected by a second detector located at a listening point and sent to a filter control circuit. The filter control circuit possesses the signal sent from the second detector and the audio signal from the audio equipment having a transfer function from the adder to the filter control circuit convoluted thereby to remove the audio signal component therefrom. The adaptive filter adaptively controls the noise signal in response to the output signal from the filter control circuit.
