Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] An energy-saving electronic ballast, which can automatically turn off two of the three 18W lamp tubes in the three-tube 18W bracket lamp or grille lamp after working late at night, so as to achieve electronic ballast to reduce energy consumption The electrical design of the device. The whole circuit is mainly divided into 2 large blocks, the electronic ballast part and the time controller part, (such as figure 1 shown). The electronic ballast part mainly includes an EMI filter, a bridge rectifier circuit, and a DC / AC inverter connected in turn, and its output is connected to the light source load to form a main circuit. The role of the electronic ballast part is to start three 18W lamp tubes And make it work stably; the time controller part is mainly composed of oscillator CD4060, counter CD4040 and normally closed relay SW connected in sequenc...

Abstract

The invention relates to an energy saving type electronic ballast, the whole circuit is divided into two blocks: an electronic ballast part and a time controller part. The electronic ballast consists of a transistor, a choke and so on, used for starting three 18W luminous tubes and make them work stably; the time controller part consists of an oscillator CD4060, a counter CD4040 and a seal-in relay SW, used for making two of the three 18W luminous tubes to turn off automatically when they works till midnight. The invention achieves the advantages of low cost and simple structure, can saves about 1 / 3 electric energy when used in the lamps in office building or supermarket, thereby has social, economic and environment protecting benefit.

Description

technical field [0001] The invention relates to the relevant technical field of lighting electric control, in particular to an energy-saving electronic ballast. Background technique [0002] The 21st century is an era of energy shortage. It is very important to save energy and reduce unnecessary energy waste. In the past, the traditional electronic ballasts for 3-tube 18W fluorescent lamps, especially in some places that need to be turned on all night (such as office buildings, large supermarkets, etc.), could not adjust and control part of the lamps to turn on and off according to needs, resulting in unnecessary energy consumption. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving electronic ballast, which solves the problem that the conventional electronic ballast for 3-tube 18W fluorescent lamps cannot adjust and control part of the lamps to turn on and off according to needs, and there is unnecessary energy consumpti...
