Patent 9551480 was granted and assigned to Osram Sylvania on January, 2017 by the United States Patent and Trademark Office.
There is herein described an LED lamp suitable for replacing conventional fluorescent lamps. The LED lamp has a tubular body and a flexible circuit board as compared to the rigid circuit boards used in other similar lamps. The flexible circuit board has a plurality of LEDs, electric circuitry for powering the LEDs, and a curvature that is maintained by a retention means. The curvature of the flexible circuit board substantially corresponds to the curvature of the tubular body which places the LEDs further away from the front surface of the lamp thereby allowing for improved diffusion and light distribution.
