Energy Saving Means Reducing Power Used By Lamps
US Patent:
4097782, Jun 27, 1978
Filed:
Dec 15, 1975
Appl. No.:
5/640980
Inventors:
Hiram Darden Chambliss - Grand Junction CO
International Classification:
H05B 3909
US Classification:
315209R
Abstract:
Energy is saved in lighting lamps by pulse operation at periodic duty cycles of less than 100% on time with little effect on apparent brightness when viewed by the normal human eye because of the quality of retention of a peak flask for a finite time. At periodic frequencies above about fourteen cycles the lamps appear to be continuously energized with little flicker.
