Patent number: 5952793Abstract: A current flowing through a discharge lamp 4 is detected by a current detecting circuit 5, and the detected current is outputted as a lamp current signal A to a feedback control circuit 7 where a difference between the lamp current signal A and the dimming control signal B is obtained and amplified, and then a simplified signal D is outputted to an adder 12 which adds the amplified signal D to the dimming control signal B to constitute a control signal E. The control signal is fed back to a high frequency power supply 2. When a comparing circuit 15 detects that the light level of the dimming control signal B with respect to the full light becomes higher than or equal to 40% to 60%, the feedback circuit is disconnected by operating a switch 13 provided between an error amplifying circuit 9 and an adder 12 to stop the feedback control.Type: GrantFiled: March 11, 1997Date of Patent: September 14, 1999Assignees: Mitsubishi Denki Kabushiki Kaisha, Mitsubishi Lighting Fixture Co., Ltd.Inventors: Kenichiro Nishi, Satoshi Nagai, Kentaro Eguchi, Takeshi Arai, Jun Bunya, Kazutaka Shimizu, Koji Shibata, Isamu Ogawa
