LED light tube
First Claim
1. An illumination device, comprising:
- a) an LED light strip having one or more arc voltage LEDs;
b) a diffusion tube having a tube length and distal ends, said diffusion tube surrounding said LED light strip;
an end cap mounted to each distal end, each said end cap having an electrical connector, said electrical connector electrically connected to said LED light strip,c) each said end cap is bonded to said diffusion tube forming a seal with said diffusion tube; and
d) a filament simulator having a first filament LED and a second filament LED;
said filament simulator includes a filament simulating circuit including a first bridge rectifier that rectifies ballast power and applies the rectified power to said first filament LED, a second bridge rectifier that rectifies ballast power and applies the rectified power to said second filament LED, and fourth rectifying diodes between said first and second bridge rectifiers;
said first and second bridge rectifiers direct power to create light from the ballast power; and
said rectifying diodes direct arc power through said one or more arc voltage LEDs to create light from the arc power.

Abstract
An illumination device used to replace fluorescent light tubes. The illumination device comprises an LED light strip, a diffusion tube surrounding the LED light strip, and an end cap mounted on each end of the tube. Electrical connectors integrated with the end caps and make electrical connection with the LED light strip. The device may be hermetically sealed, use LED'"'"'s to rectify the current, have a filament simulator with or without a visual indicator, two-sided or multi-sided light strips, light diffusing end caps and be filled with a life-extending gas. The illumination device results in an LED light tube with improved lighting uniformity, reduced energy consumption, improved ease of use and longer operating life.
