Abstract

An example light emitting diode bulb assembly includes a base having a first end portion and a second end portion defining an axis, a plurality of first light emitting diodes secured adjacent a plurality of first base surfaces about the axis, and at least one second light emitting diode secured adjacent a second base surface of the first end portion, wherein the second base surface is transverse to the plurality of first base surfaces.

Claims

1. A light emitting diode bulb assembly, comprising:

a base having a first end portion and a second end portion defining an axis;

a plurality of first light emitting diodes secured adjacent a plurality of first base surfaces about said axis; and

at least one second light emitting diode secured adjacent a second base surface of said first end portion, wherein said second base surface is transverse to said plurality of first base surfaces, wherein said first end portion includes a first feature for securing said base to one of a fixture or a second bulb assembly and said second end portion includes a second feature for securing said base to the other of said fixture or said second bulb assembly, wherein the first feature and the second feature are both recessed female-type attachment features.

2. The bulb assembly of claim 1, wherein said base is extruded.

3. The bulb assembly of claim 1, including a first lens, wherein at least one of said lens or said first base surface includes a groove for slideably receiving an extension from the other of said lens or said base.

4. The bulb assembly of claim 3, including a second lens mounted transverse to said first lens, said second lens configured to alter light from said at least one second light emitting diode.

5. The bulb assembly of claim 3, including a second lens distinct from said first lens and configured to alter light from said at least one second light emitting diode.

6. The bulb assembly of claim 1, wherein said first feature and said second feature each include a threaded portion.

7. The bulb assembly of claim 1, wherein said first feature and said second feature are each configured to receive a threaded attachment.

8. The bulb assembly of claim 1, wherein said second base surface defines a groove for receiving a fastener that holds at least one of said plurality of first light emitting diodes.
