LED fluorescent lamp tube with variable-frequency variable-voltage power supply and implementation method thereof

Abstract

The invention relates to an LED fluorescent lamp tube with a variable-frequency variable-voltage power supply and an implementation method thereof. When the traditional LED fluorescent lamp tube is used for replacing the traditional fluorescent lamp tube, circuits and even lamp structures need to be changed, and moreover, professionals are needed during replacement, which wastes plenty of expense and time. In the implementation method, a built-in variable-frequency variable-voltages power supply is used for converting input current with different voltages and frequencies into a constant current signal required by an LED; the LED fluorescent lamp tube comprises a traditional LED florescent lamp tube, a lamp holder, a lampshade and the built-in variable-frequency variable-voltages power supply;when in replacement, the lampshade of a lamp is taken down under the condition of power-off, an original lamp is taken down, a new lamp tube is assembled, a switch is turned on to check the working condition of the new lamp tube, and if the new lamp tube works normally, the lampshade can be covered. The invention has the advantages of conveniently replacing the traditional fluorescent lamp tube, being convenient and simple in replacement operation without professionals and any special tools, greatly saving cost and energy, having wide application range, and protecting environment and being beneficial to popularization.

Description

technical field [0001] The invention relates to the field of electron optics, in particular to an LED fluorescent tube with variable frequency and variable voltage power supply and a realization method thereof. Background technique [0002] When the existing LED fluorescent tubes replace the traditional fluorescent tubes, although the dimensions are exactly the same, they cannot adapt to the various current signals given by the ballasts for traditional fluorescent lamps on the market, which leads users to replace the traditional fluorescent tubes with LED fluorescent tubes. When fluorescent tubes are used, only professionals can complete the replacement work, and it is necessary to change the circuit and even the structure of the lamps, which wastes a lot of money and time. Contents of the invention [0003] The object of the present invention is to provide an LED fluorescent tube with variable frequency and variable voltage power supply and its implementation method, so t...
