Title:
ELECTRONIC BALLAST-BASED APPARATUS FOR CONTROLLING ELECTRONIC CONTROL CIRCUIT AND ILLUMINATING LAMP
Document Type and Number:
WIPO Patent Application WO/2018/024218
Kind Code:
A1
Abstract:
The present invention provides an electronic ballast-based apparatus for controlling an electronic control circuit and an illuminating lamp. The apparatus comprises an electronic ballast and an electronic control circuit that are connected to each other. The electronic control circuit comprises a filament analog circuit, a rectifier bridge circuit, at least two frequency detection circuits that are connected in parallel, an interface logic circuit, and a switch circuit. The electronic ballast is connected, sequentially through the filament analog circuit and the rectifier bridge circuit, to the switch circuit. One ends of the at least two frequency detection circuits that are connected in parallel are connected between the filament analog circuit and the rectifier bridge circuit, or are connected between the electronic ballast and the filament analog circuit, and the other ends are connected to the interface logic circuit. The interface logic circuit is connected to the switch circuit. The illuminating lamp having the apparatus can effectively avoid the turn-off flicker phenomenon of the illuminating lamp, so as to improve the user experience on the illuminating lamp.
