| 摘要 |
One aspect of the present invention is a non-electronic method of controlling the power provided to the lamp through use of multiple secondary taps off the secondary side of the HID ballast. This allows for a base capacitor to be used, along with the multiple secondary taps of the ballast, to vary the power to the lamp for purposes of providing constant light output, dimming capabilities, or to hold the power constant, or any combination of such.
