发明名称 LED flourescent lamp
摘要 An LED fluorescent lamp includes: an LED array having a plurality of LEDs connected in series; a first connection pin and a third connection pin connected to one side of the LED array; a second connection pin and a fourth connection pin connected to the other side of the LED array; at least one pair of capacitors connected to the LED array; and a short-circuit means for connecting at least one of the first connection pin and the third connection pin, and the second connection pin and the fourth connection pin, wherein the capacitors include: a first capacitor having one end connected to the first connection pin and the other end connected to one side of the LED array; a third capacitor having one end connected to the third connection pin and the other end connected to the one side of the LED array; a second capacitor having one end connected to the second connection pin and the other end connected to the other side of the LED array; and a fourth capacitor having one end connected to the fourth connection pin and the other end connected to the other side of the LED array. The LED fluorescent lamp can use an instant start electronic ballast that is a fluorescent lamp ballast installed in an existing lamp with no change.
