摘要： According to one embodiment, a power supply for lighting includes a rectifying circuit, a smoothing capacitor, and a current control circuit. The rectifying circuit rectifies a phase-controlled alternating-current voltage supplied to between a pair of input terminals. The smoothing capacitor is connected to a high-potential terminal and a low-potential terminal of the rectifying circuit. A first electric current flows to the current control circuit in a period when an absolute value of the alternating-current voltage is lower than a specified value. After a second electric current larger than the first electric current flows when the absolute value of the alternating-current voltage increases to be equal to or larger than the specified value, the current control circuit is shut off to reduce a current value to be smaller than the second electric current until the absolute value of the alternating-current voltage decreases to be lower than the specified value.

摘要： A lighting power source according to an embodiment includes a rectifying circuit, a smoothing capacitor, a reference voltage generating circuit, and a DC-DC converter. The rectifying circuit rectifies an AD voltage input thereto. The smoothing capacitor smoothes an output from the rectifying circuit. The reference voltage generating circuit generates a reference voltage on the basis of at least any one of an output voltage of the rectifying circuit and a voltage from the smoothing capacitor. The DC-DC converter includes an output element and a constant current element, and converts the voltage of the smoothing capacitor. The output element receives a supply of a voltage of the smoothing capacitor, oscillates by performing a switching operation which repeats an ON state and an OFF state when the reference voltage is relatively high, and continues the ON state when the reference voltage is relatively low.

摘要： Disclosed is an interface circuit including a rectifier circuit, a detection circuit, a first circuit, and a second circuit. The rectifier circuit rectifies an AC voltage input between a pair of input terminals. The detection circuit detects the AC voltage and outputs the result as a detection voltage. The first circuit is controlled to be turned on or off on the basis of an input first control signal, to cause a first current to flow between the input terminals in an on state and to cut off the first current in an off state. The second circuit is controlled to be turned on or off on the basis of an input second control signal, to allow a second current greater than the first current to flow between the input terminals in an on state and to cut off the second current in an off state.

摘要： A receiver includes a light-receiving portion which receives an infrared remote control signal from a transmitter, an A/D converter which converts a signal received by the light-receiving portion into a digital signal at a frequency much higher than a carrier wave, and a digital filter having the band-pass function of a pass band containing the carrier band of the infrared remote control signal for the digital signal output from the A/D converter. The digital filter reduces the influence of variations in argon spectrum intensity over time.
