Abstract
A method of forming a LED-based light for replacing a conventional fluorescent bulb in a fluorescent light fixture includes forming a heat sink by shaping an elongate sheet of highly thermally conductive material to increase a surface area to width ratio thereof mounting LEDs in thermally conductive relation with the heat sink, and enclosing the LEDs within a light transmitting cover.

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, and an elongate light transmitting cover, the method comprising:
- providing the heat sink by shaping an elongate sheet of highly thermally conductive material having opposing longitudinally extending edges to increase a surface area to width ratio thereof;
- mounting the LEDs in thermally conductive relation with the heat sink;
- and
- enclosing the LEDs within the light transmitting cover such that the longitudinally extending edges engage an interior of the cover to support the heat sink within the cover.
A method of manufacturing an elongate heat sink for use in a LED-based light for replacing a conventional fluorescent bulb in a fluorescent light fixture, the method comprising:
- shaping, to form the heat sink, a single elongate sheet of highly thermally conductive material having a width prior to shaping defined by a distance between a first longitudinally extending edge and an opposing second longitudinally extending edge to include a plurality of integral longitudinally extending planar surfaces angled relative to one another, wherein:
- the width of the sheet prior to shaping is greater than a maximal width of the heat sink after shaping, and
- the heat sink is shaped such that the opposing longitudinally extending edges are configured to engage an interior of a light transmitting cover to support the heat sink within the cover.
