Problems solved by technology
However, the length and size of the wire connecting the power grid and the light-emitting diode tube D and the number of light tubes in the power grid may cause the anti-shock protection circuit to malfunction, causing the anti-shock protection circuit to cut off the connection between the light-emitting diode tube D and the power grid
In this way, the light-emitting diode tube D cannot work normally

The invention discloses a power supply system for preventing false operation of an anti-electric shock protection function of a lamp tube and a method thereof. The power supply system for preventing false operation of the anti-electric shock protection function of the lamp tube comprises a live wire input end, a null line input end and a capacitive device. The live wire input end is connected to a first node, and the first node is used for being connected to a live wire terminal of an anti-electric shock protection circuit of a first light-emitting module. The null line input end is connected to a second node, and the second node is used for being connected to a null line terminal of the anti-electric shock protection circuit of the first light-emitting module. One end of the capacitive device is connected to the first node, and the other end is connected to the second node.
Description
technical field [0001] The invention relates to a power supply system and its method. Background technique [0002] The length of the LED light tube is about 600mm-2400mm. Such as figure 1 As shown, generally speaking, the user U will first insert one end of the LED tube D into the live wire input end L of the lamp holder, and hold the other end of the LED tube D (E indicates ground). At this time, if the light-emitting diode tube D does not have a proper protection mechanism against electric shock, the user U is likely to get an electric shock. In order to solve this problem, the light-emitting diode tube D has an anti-electric shock protection circuit to provide an anti-electric shock protection function. The anti-shock protection circuit can effectively judge whether the human body resistance is connected to the power grid, so it can effectively realize the anti-shock protection function to reduce the risk of electric shock. However, the length and size of the wire co...
