Mujibun Nisa Khan: Light distribution using tapered waveguides in LED-based tubular lamps as replacements of linear fluorescent lamps. January 5, 2012: US20120002436-A1


An LED replacement-lamp design concept comprising tapered waveguides to provide uniform and effective light distribution is disclosed. Currently, most LED-based replacement lamps for linear fluorescent lamps (LFLs) place discrete surface mount LEDs directly on a cylindrical base. This produces non-u ...
