Problems solved by technology

Due to the different driving signals, LED lamps compatible with the above-mentioned electronic ballasts may not be compatible with emergency ballasts, which is not conducive to the widespread application of LED lamps
[0007] In addition, some PS-type and IS-type electronic ballasts, when they work, the output signal contains a DC bias voltage component, which will cause misjudgment of the compatible circuit of the LED lamp, causing the LED lamp to malfunction. Work
This is not conducive to the widespread application of LED lights

Abstract

The invention discloses an LED lamp system, an LED lamp and a power supply device of the LED lamp. The power supply device is used for supplying power to an LED module and comprises a compatible circuit, a rectifying circuit and a filtering circuit, wherein the compatible circuit is used for receiving an input signal output by an electronic ballast and shielding a protection detection point of theelectronic ballast by changing the circuit characteristics of a LED lamp so as to make the electronic ballast be allowed to provide the input signal through protection detection, the rectifying circuit is coupled to the compatible circuit and is used for rectifying the received input signal so as to output a rectified signal, and the filtering circuit is coupled to the rectifying circuit and is used for filtering the rectified signal to supply power to the LED module.

Description

technical field [0001] The present application relates to the lighting field, in particular to an LED lamp system, an LED lamp and a power supply device thereof. Background technique [0002] LED lighting technology is rapidly developing to replace traditional incandescent and fluorescent lamps. Compared with fluorescent lamps filled with inert gas and mercury, LED lamps do not need to be filled with mercury. [0003] Since traditional incandescent and fluorescent lamps have been around for a long time, their connections are matched with ballasts. With the improvement of people's awareness of energy saving, it has reached a consensus that LED lighting will replace traditional incandescent and fluorescent lamps in the future. At present, there are many occasions where rectifiers are used, and it is becoming more and more urgent to consider how LED lamps are friendly and compatible with different types of existing rectifiers when replacing them with LED lamps. [0004] Comm...
