ABSTRACT:
An economical power-reducing circuit for either a fluorescent lighting fixture or for a high-intensity, low-voltage incandescent lamp has an electrolytic capacitor and a diode connected in parallel with the capacitor. When used in a fluorescent lamp fixture, the circuit reduces power consumed by the fixture, both when used as a lamp substitute or as an attachment that does not eliminate a lamp. When used with a high-intensity, low-voltage incandescent lamp, the power-reducing circuit eliminates a transformer, thus saving both cost and weight. It also should provide a power saving at no reduction in brightness, and should prolong the life of in the incandescent lamp.
