Light tube with anti-electric shock protection function and capable of being supplied with electricity by electrical ballast and alternate-current power supply in working frequency

A light tube with anti-electric shock protection function and capable of being supplied with electricity by electrical ballast and alternate-current power supply in working frequency, comprising two conductive pin assemblies disposed at two ends of the light tube and electrically connected to a mains supply;

• a bridge rectifier connected to at least one of the two conductive pin assemblies and being inputted at least one type of voltage signals;
• an anti-electric shock detection control circuit connected to the bridge rectifier and having an output end;
• a direct-current filtering circuit connected to the anti-electric shock detection control circuit and a bleeder resistor, wherein the direct-current filtering circuit performs a smoothing procedure to a direct-current pulse voltage signal which is rectified by the bridge rectifier and the direct-current filtering circuit generates a false voltage in response to an output of the anti-electric shock detection control circuit, and the bleeder resistor reduces the false voltage;
• a buck-boost constant current module having an input end connected to the output end;
• a rectifier connected to the bridge rectifier to receive a rectifying signal, wherein the rectifier is inputting the at least one type of voltage signals to the bridge rectifier, and a loop connected to the rectifier comprises at least one capacitor.
