Abstract

A universal LED tube and a power system of the universal LED tube are provided. The universal LED tube utilizes an external electric power being selectably a low frequency electric power to emit light. The universal LED tube comprises a LED unit (101) and a LED driving circuit. The LED driving circuit comprises a power converter unit (102, 102') and a power filter unit (104, 104'). The power converter unit (102, 102') provides a DC power to the LED unit (101) according to the low frequency electric power. The power filter unit (104, 104') is electrically coupled to a first side portion (1a) and the power converter unit (102, 102'). The low frequency electric power passes from the first side portion (1a) through the power filter unit (104, 104') to the power converter unit (102, 102'), for driving the LED unit (101). The universal LED tube can be applied to an existing tube holder of a conventional fluorescent tube, for avoiding cost of wire modifications.
