INTELLIGENT LED FLUORESCENT LAMP WITH AUTOMATICALLY IDENTIFYING COMPATIBILITY MODE
Document Type and Number:
WIPO Patent Application WO/2015/139365
Kind Code:
A1
Abstract:
The utility model relates to the technical field of LED fluorescent lamps, and specifically relates to a power supply device of an LED fluorescent lamp that automatically selects a single-ended or double-ended power supply. The utility model provides an intelligent LED fluorescent lamp with automatically identifying a compatibility mode. The lamp comprises an electronic ballast, a fluorescent lamp tube, a relay, a control circuit, a flyback switching circuit, a high frequency AC-DC drive circuit and a switch. The third output end and the fourth output end of the electronic ballast are respectively connected to the first pin and the second pin on the left end of the fluorescent lamp tube. The first output end and the second output end of the electronic ballast are respectively connected to the third pin and the fourth pin on the left end of the fluorescent lamp tube. The third pin and the fourth pin on the right end of the fluorescent lamp tube are shorted. The switch is used to select the first pin on the left end of the fluorescent lamp tube, and the third and fourth pin on the right end of the fluorescent lamp tube. The relay, a rectification circuit, the switch, the flyback switching circuit, and the high frequency AC-DC drive circuit are respectively electrically connected to the control circuit. The rectification circuit is also electrically connected to the switch, the flyback switching circuit, and the high frequency AC-DC drive circuit respectively.
