摘要： When an operator operates an operation tool of a dimming operation terminal device in order to set the brightness of a lighting load to desired brightness, an energization electric signal, for example, a voltage level detected by a dimming control section changes. The dimming control section generates a dimming signal modulated according to the voltage level. Power supply to the dimming control section is performed by an insulated auxiliary power supply. Transmission of the dimming signal is performed via an insulating section.

摘要： Plural luminaires are installed in a lighting space surrounded by a wall part. A sensor equipment detects existence or nonexistence of a person in the lighting space. If existence of a person in the lighting space is detected, the sensor equipment detects a direction of the person. The sensor equipment detects a distance between the wall part positioned in front of the direction of the person and the person. A lighting control unit selectively switches between a first control for performing lighting control of the luminaires to illuminate the wall part positioned in front of the direction of the person if the detected distance is a specified distance or less, and a second control for performing lighting control of the luminaires to reduce brightness at a place as the place becomes farther from a position of the person if the detected distance is larger than the specified distance.

摘要： A low-pressure mercury vapor-filled discharge lamp has a glass arc tube and a glass outer tube disposed coaxially with the arc tube forming a space therebetween. A gas is disposed in the space. The arc tube contains a gas and is coated with a phosphor. A first seal hermetically seals the inner tube. A second seal seals the inner tube to the outer tube. The inner tube further contains a pair of cathodes coupled to Dumet wires extending from the interior of the inner tube to the outside of the lamp structure. The pressure in the space is set at not more than 1 Pa, which is nearly high vacuum. The longer the radial dimension of the space, the greater the heat retaining capacity and the better the temperature characteristics which can be obtained. However, by setting the pressure of the space at 1 Pa or less, the optimum heat retaining capacity can be obtained while reducing the diameter of the low-pressure mercury vapor filled discharge lamp 1.

摘要： A power supply apparatus has a rectifier for outputting a non-smoothed DC. A switching circuit alternately shut off output of the rectifier at a high frequency, which includes first and second switches. A first capacitor couples to the first and second switches for smoothing output of the rectifier. A series resonance circuit includes a second capacitor and an inductor so that the voltage across the first capacitor becomes lower by the resonance voltage than that of the output of the rectifier. The switches are coupled to a feedback circuit including a saturatable current transformer having a primary winding and secondary winding. A control means varies the saturation time of the saturatable current transformer.

摘要： A compact fluorescent lamp unit has a phosphor coated bulb of which first and second sealed end portions. A pair of filaments is disposed in the bulb. The filament contains an emitter for enhancing thermionic emission of electrons therefrom and is caused to be cut off by the self-generated heat when the emitter is substantially dissipated. The lamp device has an inverter circuit containing a resonant capacitor disposed between each one end of the filament coils to pass a resonant current through the capacitor during the operation of the lamp. The filament coil is substantially composed of a tungsten wire having a diameter corresponding to 8 MG though 12 MG and is normally operated with a lamp current ranging from 250 mA to 350 mA. The filament coil has a cold resistance ranging from 2 .OMEGA. to 4 .OMEGA. and an output voltage of the inverter circuit exhibits more than 260 volts when the fluorescent lamp is substituted by a resistor having 5 .OMEGA..
