Publication number: 20080231816Abstract: To provide a discharge lamp lighting device which is made efficient at the time of starting to light a high-voltage discharge lamp and has quick illumination rising. To start a high-voltage discharge lamp 17 by a pulse high-voltage, the high-voltage discharge lamp 17 is controlled to have the rated power or more by duty output which is previously recorded in a control circuit 18 according to a voltage detection signal (d) and a current detection signal (e) of the lamp. For the electric power control of the control circuit 18, the rated power or more is temporarily supplied to the lamp in several tens of seconds from the start of the lamp, and then the electric power is moderately lowered to the rated power. Thus, the electric power at the time of starting to light is made efficient, and it becomes possible to make the illumination rising quick.Type: ApplicationFiled: March 21, 2008Publication date: September 25, 2008Applicant: HARRISON TOSHIBA LIGHTING CORP.Inventor: Takaaki TANAKA
