LED荧光灯
摘要：
本发明提供了一种使用多个LED作为光源的发光二极管(LED)荧光灯，它是不妨碍生态环境的并且能够有助于能量保存。该LED荧光灯包括：LED阵列，该LED阵列包括被串联地连接的多个LED；第一至第四连接引脚；第一至第四电容器，该第一至第四电容器被分别连接至第一至第四连接引脚；第一二极管，该第一二极管具有被连接至第一电容器的第二端的阳极和被连接至LED阵列的第一端的阴极；第二二极管，该第二二极管具有被连接至LED阵列的第二端的阳极和被连接至第二电容器的第二端的阴极；第三二极管，该第三二极管具有被连接至LED阵列的第二端的阳极和被连接至第三电容器的第二端的阴极；以及第四二极管，该第四二极管具有被连接至第四电容器的第二端的阳极和被公共地连接至LED阵列的第一端和第一二极管的阴极的阴极。在没有要求附加设备的安装和布线的更改的情况下，能够在各种类型的荧光灯镇流器中容易地使用LED荧光灯。
摘要（英）：

Provided is a light-emitting diode (LED) fluorescent lamp using as light sources a plurality of LEDs, which are eco-friendly and can contribute to power conservation. The LED fluorescent lamp includes an LED array including a plurality of LEDs connected in series; first through fourth connection pins; first through fourth capacitors connected to the first through fourth connection pins, respectively; a first diode having an anode connected to a second end of the first capacitor and a cathode connected to a first end of the LED array; a second diode having an anode connected to a second end ofthe LED array and a cathode connected to a second end of the second capacitor; a third diode having an anode connected to the second end of the LED array and a cathode connected to a second end of the third capacitor; and a fourth diode having an anode connected to a second end of the fourth capacitor and a cathode connected commonly to the first end of the LED array and the cathode of the first diode. The LED fluorescent lamp can be readily used in various types of fluorescent lamp ballasts without a requirement of the installation of additional equipment or the change of wiring.
