Built-in power supply type LED (Light-Emitting Diode) fluorescent tube safety power-up switch

Abstract

The invention discloses a built-in power supply type LED (Light-Emitting Diode) fluorescent tube safety power-up switch. The built-in power supply type LED fluorescent tube safety power-up switch is characterized by comprising a shell which is internally provided with two conductive electrodes, wherein an insulating gap is arranged between the two conductive electrodes; the two conductive electrodes and the insulating gap form a cavity; and the cavity is provided with a metal gravity ball which can roll on the cavity to further affect an on / off state of the switch. The built-in power supply type LED fluorescent tube safety power-up switch has the beneficial effects of improved safety and easy installation.

Description

technical field [0001] The invention relates to the LED field, in particular to a built-in power supply type LED fluorescent tube safety power-on switch. Background technique [0002] The difference between LED fluorescent tubes and fluorescent fluorescent tubes is that the wiring method of built-in power supply type LED fluorescent tubes is strictly restricted by safety certification. Since the driving power of the LED fluorescent tube is built-in, the power supply cannot be supplied from both ends of the fluorescent tube like the fluorescent tube. If the power supply from both ends of the lamp tube is used, since the LED drive power supply uses a bridge rectifier for the subsequent circuit, then when one end of the built-in fluorescent tube contacts the electrode of the lamp holder, the other end of the lamp tube It will carry the AC voltage of the power supply grid, and the human body will get an electric shock when it comes into contact with it. This is strictly restric...

AI Technical Summary

Problems solved by technology

[0003] 1) Potential safety hazards of one-end power supply: LED fluorescent tubes use one-end power supply, and there may be a short circuit due to the short distance between the two pins at one end;

[0004] 2) The installation of the lamp tube is inconvenient: since one end supplies power and the other end does not, when installing the lamp tube, there will be a 50% chance that the lamp tube will not be powered on. Rotate 180 degrees to reinstall, increasing the time and difficulty of installation;

[0005] 3) Different from the power supply method of traditional fluorescent fluorescent tubes, it is easy for people to make mistakes when modifying the circuit
