Problems solved by technology

[0011] In addition, due to the difference in device selection of some signal electronic ballasts on the market, when some electronic ballasts are used in conjunction with LED fluorescent lamps (when the LED fluorescent lamp is working, the impedance is non-linear), the output output is The high-frequency current has roughly changed periodically (the frequency of the periodic change is more sensitive to the human ear, and the noise caused by the current change can be heard)

Abstract

The invention discloses an LED fluorescent lamp which comprises an LED module which is capable of emitting light and comprises at least one LED assembly, a rectification circuit for rectifying an alternating current signal output by a ballast to form a rectified signal, and a mode determining circuit which is configured to detect a state of the rectified signal and determining that the LED module executes a first luminous mode or a second luminous mode according to the state of the rectified signal, wherein when determining that the LED module executes the first luminous mode, the mode determining circuit continuously conducts current until no power is supplied to the LED module; and when determining that the LED module executes the second luminous mode, the mode determining circuit enables the current passing through the LED module to be adjusted.

Description

technical field [0001] The present application relates to the field of lighting fixtures, in particular to an LED fluorescent lamp. Background technique [0002] Since traditional fluorescent tubes have been used for decades, various countries and manufacturers have developed ballasts of various principles and specifications. Therefore, in the process of replacing traditional fluorescent lamps with LED fluorescent lamps, it is necessary to solve the problem of LED fluorescent lamps on electronic ballasts and inductors. Ballast compatibility issues. [0003] The LED fluorescent lamps currently used have many problems in compatibility with electronic ballasts and magnetic ballasts. They can work normally on magnetic ballasts, but on electronic ballasts, LED fluorescent lamp tubes may flicker, Dimming, or even burning, need to develop different LED fluorescent tube power supplies for different ballasts, which greatly increases the cost of LED fluorescent lamps replacing tradit...
