Claim Text:
1. An LED driver circuit for fluorescent tube replacement comprising: a) a tube for enclosing an LED light source, the tube having a first end cap and a second end cap, each of the first and second end caps having respectively a first pair of electrode pins and a second pair of electrode pins; b) a rectifier circuit comprising a first rectifier sub-circuit connected to the first pair of electrode pins and a second rectifier sub-circuit connected to the second pair of the electrode pins, each rectifier circuit having at least a first input diode and a second input diode, each of the input diodes having an input lead connected to one of the electrode pins, and the input diodes having output leads that are connected to provide DC output from the rectifier circuit; in which DC output from the rectifier circuit is conducted to a constant current circuit that converts the DC output from the rectifier circuit into constant DC output for driving the LED light source.
