Abstract

A light emitting diode (LED) assembly that is used in place of a horizontal incandescent tube light in a standard interior horizontal tube light fixture. The LED assembly includes a small printed circuit board (PCB) with a plurality of LED'"'"'s mounted perpendicularly thereon. During installation, the existing horizontal incandescent tube is removed and replaced with an LED assembly so that the LEDs fit into the center of the reflector. Attached to the opposite sides of the PCB are two, upward extending conductor arms that snap-fit into the two existing end conductors. The PCB includes a lighting circuit that allows the assembly to connect without regard to the polarity.

Claims

1. An incandescent tube LED replacement assembly for an incandescent light assembly that includes two upward extending contact arms capable of holding an incandescent tube at its opposite ends and a reflector with a central opening formed therein, said LED replacement assembly comprising:

a. a printed circuit board;

b. a plurality of LEDs mounted centrally on said top surface of said printed circuit board; and

,

c. two upward extending conducting arms mounted on said printed circuit board, each conducting arm including an adaptor to fit into the end connectors to electrically connect said printed circuit board to said tube end connectors.

2. The replacement assembly, as recited in claim 1, wherein each said conducting arm includes an adaptor that snap fits into said contact arms.

3. The replacement assembly, as recited in claim 1, further including a reflector with a center hole through which said LEDs extend.

4. The replacement assembly, as recited in claim 2, further including a pair of insulators located around said conducting arms to prevent electrical shorts with said reflector.

5. The replacement assembly, as recited in claim 2, further including a bridge rectified circuit on said printed circuit board.
