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.
