Abstract

In various embodiments, a light emitting diode (LED) tube lamp is provided along with a method of installing the LED tube lamp into a lighting fixture. In various embodiments, the LED tube lamp comprises: a tube; at least one LED positioned within the tube; and a passage formed through at least a portion of the tube, the passage configured to receive there-through a set of electrical connecting wires, wherein a first end of the electrical connecting wires comprises at least one of a two- or three-prong polarized plug. Various embodiments may further comprise a driver circuit positioned within the tube, the driver circuit comprising a second end of the electrical connecting wires. In various embodiments, the LED lamp tube may further comprise at least one end cap disposed on an end of the tube and at least one pin secured thereon wherein the pin is electrically isolated from the LED.

First claim

The invention claimed is:

1. A light emitting diode (LED) lamp tube comprising:
a member comprising a first end surface, a second end surface, and an intermediate surface substantially between said first and second end surfaces, said surfaces collectively defining an interior face and an exterior face of said member, said exterior face being oppositely orientated relative to said interior face, said interior face further defining an interior cavity of said member, wherein said member is sized to be mounted within a lighting fixture;
one or more LEDs positioned within said interior cavity and adjacent said intermediate surface;
at least one driver circuit positioned within said interior cavity, said at least one driver circuit being in electrical connection with said at least one LED; and
one or more pins secured on each of said first and second end surfaces, wherein at least a portion of each of said one or more pins is disposed external said interior cavity and configured to mechanically mount said LED lamp tube to said lighting fixture, and wherein each of said one or more pins is electrically isolated from said lighting fixture.

2. The LED lamp tube of claim 1 , wherein said first and said second end surfaces comprise corresponding first and second end caps, and wherein said one or more pins are secured on at least one of said first and second end caps.

3. The LED lamp tube of claim 1 , wherein said one or more pins are configured for mechanically mounting the LED lamp tube within at least one of a T8 and a T12 lighting fixture.

4. The LED lamp tube of claim 1 , wherein said one or more pins are further electrically isolated from said at least one driver circuit.

5. The LED lamp tube of claim 1 further comprising a set of electrical connecting wires having a first end and second end, wherein said first end is in direct electrical communication with said at least one driver circuit and said second end is configured for connecting to line voltage.

6. The LED lamp tube of claim 5 wherein said at least one driver circuit is configured to receive line voltage from the set of electrical connecting wires and provide a controllable current to the at least one LED.

7. The LED lamp tube of claim 5 wherein said second end comprises either (a) a two- or three-prong polarized plug or (b) one or more quick connect connectors for connecting to line voltage.

8. The LED lamp tube of claim 1 , wherein the one or more LEDs comprise a plurality of LEDs, said plurality of LEDs spaced along a length of said substantially elongate member.

9. The LED lamp tube of claim 1 , wherein the one or more LEDs comprise at least two LEDs, at least one of the at least two LEDs configured to emit light of a first color temperature and another of the at least two LEDs configured to emit light of a second color temperature, wherein the first and second color temperatures are different.

10. The LED lamp tube of claim 1 wherein at least a portion of the intermediate surface is made of a transparent or translucent material and at least one of said one or more LEDs are positioned such that at least a portion of the light emitted by the at least one of said one or more LEDs is incident upon the interior face of the portion of the intermediate surface.

11. The LED lamp tube of claim 1 wherein at least a portion of the intermediate surface is configured to radiate heat emitted by the at least one driver circuit, the one or more LEDs, or both.

12. The LED lamp tube of claim 1 wherein said at least one driver circuit is configured to convert line voltage to a controlled DC voltage.

13. The LED lamp tube of claim 1 wherein said member is elongate in shape.

14. A lighting device comprising:
one or more LED lamp tubes, wherein each LED lamp tube comprises:
a member comprising a first end surface, a second end surface, and an intermediate surface substantially between said first and second end surfaces, said surfaces collectively defining an interior face and an exterior face of said member, said exterior face being oppositely orientated relative to said interior face, said interior face further defining an interior cavity of said member wherein said member is sized to be mounted within the lighting device;
one or more LEDs positioned within said interior cavity and adjacent said intermediate surface;
at least one driver circuit positioned within said interior cavity, said at least one driver circuit being in electrical connection with said at least one LED; and
one or more pins secured on each of said first and second end surfaces, wherein at least a portion of each of said one or more pins is disposed external said interior cavity and configured to mechanically mount each of said LED lamp tube to said lighting device, and wherein each of said one or more pins is electrically isolated from said lighting device.

15. The lighting device of claim 14 further comprising a set of electrical connecting wires having a first end and second end, wherein said first end is in direct electrical communication with said at least one driver circuit and said second end comprises either (a) a two- or three-prong polarized plug or (b) one or more quick connect connectors for connecting to line voltage.

16. The lighting device of claim 14 , wherein a current provided to the one or more LEDs of each LED lamp tube may be controlled by the at least one driver circuit of the corresponding LED lamp tube.

17. The lighting device of claim 16 wherein the lighting device comprises a first LED lamp tube and a second LED lamp tube and the first current provided to the one or more LEDs of the first LED lamp tube is controlled independently of the second current provided to the one or more LEDs of the second LED lamp tube.

18. The lighting device of claim 14 , wherein said first and said second end surfaces of each LED lamp tube comprise corresponding first and second end caps, and wherein said one or more pins are secured on at least one of said first and second end caps.

19. The lighting device of claim 14 , wherein said one or more pins are further electrically isolated from said at least one driver circuit.

20. The lighting device of claim 14 further comprising one or more tombstones configured to mechanically mount the one or more LED lamp tubes by said at least one pin, wherein said one or more tombstones are electrically isolated from line voltage.
