    Abstract: An illumination system includes illumination devices, an imaging device and a control device. Each of the illumination devices includes a light source, a lighting circuit unit and a transmission control unit. The control device includes a storage unit, a transmission processing unit and a main control unit for selecting a control-target illumination area, reading out the identification code corresponding to the selected illumination area from the storage unit and causing the transmission processing unit to transmit a signal containing a control command on the illumination device. The main control unit is operable in an initial setting mode in which the correlations between the identification codes of the illumination devices and the illumination areas are set by causing the imaging device to take an image of the illumination space while turning on the illumination devices and detecting the illumination area of each of the illumination devices from the image thus taken.

  • Patent number: 8040074
    Abstract: There is provided a discharge-lamp lighting device that, upon start-up of a high-intensity discharge lamp, alternately outputs a period A during which a starting circuit applies a high voltage to the high-intensity discharge lamp by resonance operation when a DC/AC inverter outputs a high-frequency voltage, and a period B during which the DC/AC inverter applies a low-frequency-square-wave voltage or a DC voltage to the high-intensity discharge lamp via the starting circuit. The period A for applying the high voltage by the resonance operation is set to about a time enough for a high-intensity discharge lamp in an initial aging stage to cause a dielectric breakdown, and a period C for alternately outputting the high-voltage generating period A and the period B for outputting the low-frequency-square-wave voltage or the DC voltage is set to about a time enough for a high-intensity discharge lamp in a life's last stage to cause a dielectric breakdown.
