Abstract

A light emitting diode lamp for use in a brake light bulb socket of an automobile or similar vehicle has first and second printed circuit boards having first and second pluralities of light emitting diodes mounted thereupon for emitting monochromatic light in response to power signals supplied from the automobile. The light emitting diode lamp further includes a body adapted to form a bayonet connection, a base having at least one contact, and a support sleeve having a wiring conduit, a support tray, and at least two support stanchions for supporting the first printed circuit board. Finally, the light emitting diode lamp includes at least one resistor electrically connected between the at least one contact and a first wire that is electrically connected to the first and second printed circuit boards.

Claims

1. A light emitting diode lamp comprising:

a first printed circuit board having a first top surface and a first bottom surface;

a second printed circuit board having a second top surface and a second bottom surface;

a first plurality of light emitting diodes mounted on and generally normal to the first top surface and electrically coupled with the first printed circuit board;

a second plurality of light emitting diodes mounted on and generally parallel to the second top surface and electrically coupled with the second printed circuit board;

a body having a first end, a second end, and a body sidewall defining a cavity within the body, the body sidewall having two alignment pins extending therefrom;

a base having at least one contact, the base being attached to the second end of the body;

a support sleeve having a wiring conduit, a support tray, and at least two support stanchions,

the support tray being shaped to support the second printed circuit board, and

the at least two support stanchions extending upwardly from the support tray to support the first printed circuit board above and generally parallel to the first printed circuit board; and

an electrical control means electrically connecting the at least one contact with the first and second printed circuit boards.

2. The light emitting diode lamp of claim 1 further comprising a lens cap having a planar front face integrally formed with a cylindrical lens sidewall that terminates in a lens perimeter, and wherein the support tray has an tray perimeter adapted to engage the lens perimeter.

3. The light emitting diode lamp of claim 1 wherein the support sleeve is constructed of polycarbonate.
