1. An assembly to supplant fluorescent lighting in backlit signs or area lighting with a two dimensional array of LEDs comprising:
- a frame including an elongated support member and a plurality of angled members arranged transverse to the elongated support member at opposite ends there from;
a plurality of adapters provided on each on of the plurality of angled members and configured to be received by conventional fluorescent lamp receptacles;
an LED assembly including a plurality of LED modules having a printed circuit board, at least one LED array including a plurality of light emitting diodes on a surface of the printed circuit board, and current conditioning circuitry;
wherein the LED modules are mounted parallel to and spaced from each other on at least one side surface of the elongated support member;
a power source attached to the frame at one of the opposite ends of the elongated support member;
at least one power cord, the LED modules being daisy-chained together by the power cord.

Abstract
The present invention relates to an LED assembly designed to supplant fluorescent tubes, comprising: an array of standardized LED modules affixed to a lightweight frame resulting in a uniform two dimensional array of LEDs casting their light directly onto a translucent sign panel or, alternatively, a light defusing panel for area lighting. When the application is to retrofit a fixture with fluorescent tubes, the assembly is provided with adapters that attach to the fluorescent tube receptacles.
