摘要
An electronic ballast is provided with a built-in timed electric power saver and with photoelectric switching for high-pressure mercury vapor, metallic vapor and sodium vapor lamps. The electronic ballast with the built-in timed saver and photo-electric switching for high-pressure mercury vapor, metallic vapor and sodium lamps includes an electronic circuit having as a principle the obtaining of an increase in the frequency of the electric power distribution network. This increase is accomplished by means of a switching that results in a current limiting electronic device, which also is able to incorporate a timed electric power saver, the utilization of a single equipment for various lamp lower ratings, a photo-sensitive element for control of the lamp switching in accordance with the lighting level of the installation site and an ignitor for lamps requiring a voltage higher than the rated one.
