Abstract
A light emitting diode (LED) tube and an LED lamp using the same are provided. The LED tube is suitable for direct installation in a lamp holder which has a starter and a ballast. The LED tube includes an LED array, an LED driver, and a rectification-block diplexer. When the LED array is driven by the LED driver, the rectifier-block diplexer disables the starter and the ballast and at the same time receives and converts an AC power supply. Thus the rectifier-block diplexer provides an operating voltage to the LED driver. Without removing the starter and shorting the ballast, the user can easily install the LED tube into a traditional fluorescent lamp socket, saving the cost of lamp modification, thus achieving the purpose of energy saving and environmental protection.
