説明

The ballasts for discharge lamp are desirable to be small size, light weight and energy saving type for general illumination. In addition, the continuous dimming also will meet a demand of suitable illumination. For the purpose, the ballasts of high frequency operation and also the dimming control of fluorescent lamps have been already developed and been practically used. But the practical high frequency operation of HID lamps for general use has not been virtually realized mainly due to the unstable operation of acoustic resonance phenomenon and the difficulty of noise suppression although HID lamps have been used for many field in favor of high efficacy.<BR>The authors have resolved the former problem selecting an operating frequency beyond 100 kHz and then experimentally examined the high frequency operation and its dimming control of HID lamps, for the latter problem presupposing that the conductive glass or plastics, for example, might be adapted for the shield of electromagnetic waves in the future.<BR>This paper describes the circuit configuration consisted of HID lamps, here mainly high pressure sodium lamp and MOS-FET push-pull inverter, and experimental results on high frequency operation from 100 kHz to about 400 kHz and its continuos dimming control over the range from 100 percent to about a few percent.
