Patent ID: 11122671

Abstract:
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 includes two conductive pin assemblies, a bridge rectifier, an anti-electric shock detection control circuit, a direct-current filtering circuit, a bleeder resistor, a buck-boost constant current module, and a rectifier. The direct-current filtering circuit is connected to the anti-electric shock detection control circuit and the bleeder resistor. The direct-current filtering circuit performs a smoothing procedure to a direct-current pulse voltage signal which is rectified by the bridge rectifier, the direct-current filtering circuit generates a false voltage to the anti-electric shock detection control circuit, and the bleeder resistor reduces the false voltage. The rectifier is connected to the bridge rectifier to receive a rectifier circuit, and the electrical ballast inputs the voltage signal to the bridge rectifier.
