METHOD OF FORMING LED-BASED LIGHT AND RESULTING LED-BASED LIGHT
First Claim
1. A method of forming a LED-based light for replacing a conventional fluorescent bulb in a fluorescent light fixture and including a plurality of LEDs, an elongate heat sink, an elongate light transmitting cover, and at least one electrical connector, the method comprising:
- providing the heat sink by shaping an elongate sheet of highly thermally conductive material to increase a surface area to width ratio thereof;
mounting the LEDs in thermally conductive relation with the heat sink along its length; and
enclosing the LEDs within the light transmitting cover.

Abstract
A method of forming a LED-based light for replacing a conventional fluorescent bulb in a fluorescent light fixture includes shaping an elongate sheet of highly thermally conductive material to fashion a heat sink. Shaping the heat sink allows fashioning the heat sink to define cover and end cap attachment structures, surfaces for mounting LEDs at various angles, and a high surface area to width ratio for dissipating heat.

20. An LED-based light for replacing a conventional fluorescent light bulb a in fluorescent light fixture, the LED-based light comprising:
-
a hollow, cylindrical light transmitting tube; a heat sink shaped from a sheet of highly thermally conductive material having a width greater than a maximal width of the tube, the heat sink having a central planar portion and two side portions extending perpendicularly to the planar portion from opposing ends of the planar portion, the heat sink positioned within the tube with the side portions hi contact with an interior of the tube; a printed circuit board mounted on the central planar surface; multiple LEDs longitudinally spaced along the length of the circuit board; and two end caps coupled to opposing ends of the tube, the end caps carrying bi-pin connectors in electrical communication with the circuit board.
