TH17332A - "Electronic ballast with time-saving energy saver and photovoltaic switch for light bulbs" - Google Patents

Abstract

Electronic ballast provided with a time electric power saver. And with the internal power switch for mercury vapor lamps Metal-vapor and high-pressure sodium vapor, electronic ballasts with a time saver and photovoltaic switch built in. For mercury vapor lamps This high-pressure metal-vapor and sodium vapor will include electronic circuits that are principled to achieve an increase in the frequency of the power distribution network. This increase will be accomplished through a method of Switching, which will have an effect on electronic devices in current limiting, which can also be combined with a time-saving electric energy saver as well, the use of this single device for different types of light bulbs. With a lower rate Light sensitive area to control the lamp switch according to the lighting level of the installation site. And the igniter for the lamp will need a certain higher voltage than a reasonable value.
