LED fluorescent lamp

Abstract

The invention provides an LED fluorescent lamp. The LED fluorescent lamp comprises two bridge rectifiers and an LED modulator tube, wherein the positive electrodes of the direct current output ends of the two bridge rectifiers are connected with the input end of a constant-current circuit; the output end of the constant-current circuit is connected with the positive electrode of a light emitting diode; the negative electrode of the light emitting diode is connected with the negative electrodes of the direct current output ends of the two bridge rectifiers; the light emitting diode is located in the LED modulator tube; two alternating current input ends of one of the bridge rectifier are arranged at one end of the LED modulator tube; two alternating current input ends of the other bridge rectifier are arranged at the other end of the LED modulator tube. Any two alternating current input ends are selected from the four alternating current input ends of the two ends of the LED modulator tubes to be connected, so that the LED fluorescent lamp can normally work. The LED fluorescent lamp can meet the connection requirements of domestic and overseas lamp holders at the same time, achieve generalized installation, reduce installation difficulty, decrease the speed of elimination of old lamp holders, achieve reutilization of resources and save existing resources.

Description

technical field [0001] The invention relates to a fluorescent lamp, in particular to an LED fluorescent lamp. Background technique [0002] As the country vigorously promotes the implementation of energy-saving and emission-reduction strategies, LED fluorescent lamps are more and more widely used due to their energy-saving and environmental protection features, and there is a tendency to gradually replace traditional fluorescent lamps. However, the lamp holders of traditional fluorescent lamps are equipped with inductive or electronic ballasts. When installing LED fluorescent lamps, it is necessary to modify the circuit inside the lamp holder, which is labor-intensive and time-consuming. In addition, the fluorescent lamp lamp holders in my country use double-ended power supply, but the lamp holders of fluorescent lamps in many countries use single-end power supply. The existing LRD Fluorescent lamps cannot be universalized. [0003] How to make LED fluorescent lamps not only ...
