1. An LED lighting assembly comprising:
- a bendable thermally conductive member having a first surface and including a substantially central portion and a plurality of projecting bendable portions;
a layer of dielectric material positioned on said first surface of said thermally conductive member, including on said substantially central portion and said plurality of projecting portions;
a circuit formed on said layer of dielectric material, said circuit adapted for being electrically coupled to a power source for providing electrical power to said LED lighting assembly; and
a plurality of LEDs, each of said LEDs including a body, a lens and a plurality of projecting conductive leads, selected ones of said LEDs being positioned on one of said bendable projecting portions of said thermally conductive member and electrically coupled to said circuit formed on said layer of dielectric material and adapted for receiving said electrical power from said power source, said layer of dielectric material including a plurality of openings therein, each of said LEDs being positioned within a respective one of said openings so as to be thermally coupled to said first surface of said thermally conductive member.

Abstract
An LED lighting assembly including a plurality of individual LEDs mounted on a common, bendable heat sinking member designed to remove heat from the LEDs during operation and also to be formed (bent) to provide the desired light direction and intensity. Several such assemblies may be used within an LED lamp, as also provided herein. The lamp is ideal for use within medical and dental environments to assure optimal light onto a patient located at a specified distance from the lamp.
