Abstract

A lamp bar may include and/or involve multiple LED light sources linearly arranged along a length of the lamp bar.

Claims

1. A lamp bar comprising:

multiple LED light sources linearly arranged along a length of the lamp bar.

2. The lamp bar of claim 1, wherein the multiple LED light sources linearly arranged along a length of the lamp bar further comprises:

multiple LED light sources arranged at regular intervals along the length of the lamp bar.

3. The lamp bar of claim 1, wherein the multiple LED light sources linearly arranged along a length of the lamp bar further comprises:

multiple LED light sources linearly arranged at cutouts along the length of the lamp bar.

4. The lamp bar of claim 1, wherein the multiple LED light sources linearly arranged along a length of the lamp bar further comprises:

multiple LED light sources linearly arranged along the length of a T8 or T12 profile aluminum extrusion.

5. The lamp bar of claim 1, wherein the multiple LED light sources linearly arranged along a length of the lamp bar further comprises:

multiple LED light sources linearly arranged along the length of a T5 profile aluminum extrusion.

6. The lamp bar of claim 1, wherein the multiple LED light sources linearly arranged along a length of the lamp bar further comprises:

each LED light source attached to a moveable base formed to slide within a channel formed in an upper half of the lamp bar.

7. The lamp bar of claim 6, wherein the each LED light source attached to a moveable base formed to slide within a channel formed in an upper half of the lamp bar further comprises:

the moveable base also formed to slide within a channel formed in a lower half of the lamp bar, and further formed to accept a bolt descending from the upper half to the lower half, the upper and lower halves fitting together to form a lip so that tightening the bolt urges the moveable base against the lip thus urging the lower half against the upper half.

8. The lamp bar of claim 1, further comprising:

the lamp bar comprising a single extruded part forming slots to retain circuit boards to which the LED light sources are mounted.

9. The lamp bar of claim 8, wherein the lamp bar comprising a single extruded part forming slots to retain circuit boards to which the LED light sources are mounted further comprises:

the single extruded part further forming slots to retain a snap-in cover.

10. The lamp bar of claim 1, further comprising:

the lamp bar comprising upper and lower extruded parts formed to fit together.

11. The lamp bar of claim 1, further comprising:

each LED light source comprising a mount and control circuit, and each coupled to its own moveable base within the light bar.

12. A U-shaped lamp bar comprising:

multiple LED light sources arranged along the lamp bar.

13. A substantially circular lamp bar comprising:

multiple LED light sources arranged along the lamp bar.
