LED LIGHT TUBE COMPATIBLE WITH LIGHT FIXTURE HAVING ELECTRONIC BALLAST OR MAGNETIC BALLAST

摘要

The LED light tube compatible with a light fixture having an ballast has a translucent tube and an LED light bar mounted in the translucent tube. and having at least one waveform conversion circuit having multiple rectifier diodes and at least one LED light string connected to the at least one waveform conversion circuit, wherein a recovery time of each rectifier diode is under 1 μs; the ballast determines the at least one waveform conversion circuit and the at least one LED light string as low impedance loads, thus, the ballast does not output a high voltage AC power and burn the LED light tube; a recovery time of each rectifier diode is also short such that the LED light tube can endure a high frequency AC power outputted by the ballast. As such, the LED light tube is compatible with the light fixture.
