Abstract

A pivotable LED light bulb apparatus comprising a housing and an LED assembly. The housing has a lower portion attachable to a light socket and an upper portion. The upper portion has an LED assembly with a plurality of LED elements disposed thereon. The lower portion of the housing pivots relative to the upper portion of the housing.

Claims

1. A pivotable LED light bulb apparatus comprising:

a housing having a lower portion and an upper portion, the lower portion includes a body and a lower cap base, the lower cap base including a thread structurally configured to engage a threaded light socket, the body including a lower rotation coupling, the upper portion including a upper rotation coupling rotatably coupled to the lower rotation coupling of the lower portion, the upper portion having an upstand portion extending away from the lower portion, the upstand portion having a front face; and

an LED assembly including a base support strip member on the front face of the upstand portion, the base support strip member having at least a plurality of LED elements disposed thereon, wherein the LED elements are electrically coupled to the light socket.

2. The pivotable LED light bulb apparatus of claim 1 wherein the lower cap base has a thread axis of rotation within the threaded light socket, and wherein the upper portion rotates relative to the lower portion about a housing axis, the housing axis being collinear with the thread axis of rotation.

3. The pivotable LED light bulb apparatus of claim 2 wherein the front face is substantially planar and defines a plane, with the plane being substantially parallel to the housing axis.

4. The pivotable LED light bulb apparatus of claim 3 wherein the front face is substantially planar and defines a plane, the housing axis lies in the plane defined by the front face.

5. The pivotable LED light bulb apparatus of claim 4 wherein the upstand portion further includes a back face opposite the front face, the back face having a plurality of buttresses extending therefrom.

6. The pivotable LED light bulb apparatus of claim 5 wherein the buttresses are substantially perpendicular to the back face.

7. The pivotable LED light bulb apparatus of claim 1 wherein the base support strip member further includes a central strip portion and a pair of opposing side strip portions, each of the central strip portion and the pair of opposing side strip portions each having a plurality of LED elements positioned thereon and in electrical communication with the lower cap base.

8. The pivotable LED light bulb apparatus of claim 7 wherein the pair of opposing side strip portions are substantially mirror images of each other about the central strip portion, and wherein the central strip portion is parallel to each of the opposing side strip portions.

9. The pivotable LED light bulb apparatus of claim 1 wherein the lower portion is pivotable relative to the upper portion through an angular rotation of approximately 90°

.

10. The pivotable LED light bulb apparatus of claim 1 wherein the lower portion is pivotable relative to the upper portion through an angular rotation that is less than 360°

, and wherein full rotation is precluded.

11. The pivotable LED light bulb apparatus of claim 1 wherein the upper and lower rotation couplings define a circular configuration in a rotation plane, with the upstand portion extending substantially perpendicular to the rotation plane, the upstand portion having a thickness substantially smaller than a diameter of the circular configuration.

12. The pivotable LED light bulb apparatus of claim 1 wherein the upstand portion further includes a back face, with the front face and the back face being substantially parallel to each other to, in turn, define an upstand portion having a substantially uniform thickness.

13. The pivotable LED light bulb apparatus of claim 1 wherein the lower portion further includes a lower radiating portion which is conically shaped between the lower cap base to the lower rotation coupling, the lower rotation coupling defining a substantially circular configuration and the lower cap base, the lower radiating portion and the lower rotation coupling having a matching central axis extending therethrough.

14. The pivotable LED light bulb apparatus of claim 1 wherein the plurality of LED elements are spaced apart a predetermined distance from each other.

15. The pivotable LED light bulb apparatus of claim 14 wherein the plurality of LED elements direct light in an orientation that is generally perpendicular to the front face.
