Abstract
A lamp, and a method of assembling the lamp, includes a heat sink, a heat conductive post extended longitudinally from the heat sink where the post has longitudinal faces that each has a longitudinally extending slot therein, a metal clad circuit board slid into each slot so that each circuit board is in thermal communication with the post where each circuit board has an exterior surface with an LED thereon, and a cap on top of the post where the cap abuts lateral end surfaces of the circuit boards. The cap may hold the circuit boards in their respective slots.

23. A method of assembling a lamp comprising the steps of:
-
providing a heat sink having a first electrical connection thereon;
attaching a heat conductive post to said heat sink, said post extending longitudinally from said heat sink and having a bottom in thermal communication with said heat sink, said post having plural longitudinal faces where each of said longitudinal faces has a longitudinally extending slot therein;
sliding a respective metal clad circuit board into each said slot so that each said circuit board is in thermal communication with said post, each said circuit board having (a) a first lateral end surface abutting one of said heat sink and said first electrical connection, (b) an exterior longitudinal surface with at least one LED thereon and (c) a second electrical connection adjacent to the first lateral end surface of said circuit board, and (d) a circuit connecting said LED to said second electrical connection;
electrically connecting said first and second electrical connections to each other; and
holding each said circuit board in a respective said slot by attaching a cap on a top of said post opposite said heat sink, said cap abutting a second lateral end surface of each said circuit board opposite said first lateral end surface, each said circuit board being captured between said cap and one of said heat sink and said first electrical connection. - View Dependent Claims (24)
