Abstract

A lighting device may include an electrical base, a stabilizer adapted to be matingly connected to the electrical base, a body member, and an optic connected to the body member and defining an optical chamber. A light source may be positioned within the optical chamber and in electrical communication with the electrical base. The stabilizer may be transitionable from an engaged position with the electrical base and a disengaged position with the electrical base. The disengaged position allows for the stabilizer to be translated longitudinally with respect to the base member. The engaged position slidably fixes the stabilizer with respect to the heat sink by reducing space between the electrical base, the enclosure and the heat sink.

First claim

What is claimed is:

1. A lighting device comprising:
an electrical base;
a stabilizer adapted to be matingly connected to the electrical base;
a body member engaged with the stabilizer;
an optic connected to the body member and defining an optical chamber; and
a light source positioned adjacent to the body member, within the optical chamber, and positioned in electrical communication with the electrical base;
wherein the stabilizer is moveable from an engaged position with the electrical base and a disengaged position with the electrical base;
wherein the disengaged position allows for the stabilizer to translate longitudinally with respect to the body member; and
wherein the engaged position prevents the stabilizer from translating longitudinally with respect to the body member.

2. The lighting device of claim 1 wherein the stabilizer is substantially cylindrical.

3. The lighting device of claim 1 wherein the stabilizer includes a bottom portion configured to matingly engage the electrical base, an intermediate portion, and a top portion.

4. The lighting device of claim 3 wherein a spacer is positioned between the electrical base and the body member adjacent to the intermediate portion of the stabilizer.

5. The lighting device of claim 3 wherein the light source comprises a circuit board and a plurality of light sources mounted thereto, the circuit board having an aperture formed therein along a medial portion thereof; wherein the bottom portion of the stabilizer is threaded; wherein an interior portion of the electrical base is configured to threadably connect to the bottom portion of the stabilizer; wherein the top portion of the stabilizer comprises an engaging member adapted to pass through the aperture of the circuit board; wherein rotation of the electrical base in a first direction causes the stabilizer to be positioned in the engaged position so that the engaging member of the stabilizer engages the circuit board; and wherein rotation of the electrical base in a second direction causes the stabilizer to be positioned in the disengaged position so that the engaging member of the stabilizer disengages the circuit board.

6. The lighting device of claim 5 wherein the plurality of light sources comprise light emitting diodes (LEDs) that are positioned circumferentially on the circuit board.

7. The lighting device of claim 5 wherein the stabilizer is configured to exert a force on the circuit board when in the engaged position.

8. The lighting device of claim 1 wherein the optic comprises an upper section and a lower section.

9. The lighting device of claim 8 wherein the upper section of the optic includes a plurality of vents.

10. The lighting device of claim 8 wherein the upper section is configured to interface with each of the circuit board and the lower section; wherein the circuit board is configured to exert a generally downward force upon the upper section when the stabilizer is in the engaged position, and wherein the upper section is configured to exert a generally downward force on the lower section when the stabilizer is in the engaged portion.

11. The lighting device of claim 10 wherein the upper section comprises a ridge; and wherein the ridge is configured to interface with the circuit board.

12. The lighting device of claim 8 wherein the upper section is configured to interface with the lower section; wherein the upper section comprises a connecting member configured to interface with the stabilizer; wherein the stabilizer is configured to exert a generally downward force upon the connecting member when the stabilizer is in the engaged position; and wherein the upper section is configured to exert a generally downward force on the lower section when the stabilizer is in the engaged position.

13. The lighting device of claim 12 further comprising a crush member; wherein the crush member is positioned between and configured to interface with each of the connecting member and the light source.

14. The lighting device of claim 1 wherein the body member is a heat sink; and wherein the body member is positioned in thermal communication with at least one of the light source and the stabilizer.

15. A lighting device comprising:
an electrical base having a threaded interior portion;
a stabilizer having a threaded bottom portion that threadably connects to the electrical base, and an engaging member on a top portion;
a body member;
an optic connected to the body member and defining an optical chamber;
a light source positioned within the optical chamber and in electrical communication with the electrical base, the light source comprising a circuit board and a plurality of LEDs circumferentially mounted thereto, the circuit board having an aperture formed therein along a medial portion thereof; and
a spacer positioned between the electrical base and the body member adjacent to an intermediate portion of the stabilizer;
wherein the engaging member of the stabilizer is adapted to pass through the aperture of the circuit board;
wherein rotation of the electrical base in a first direction causes the stabilizer to be positioned in an engaged position defined as the stabilizer being prevented from translating longitudinally relative to the body member and the engaging member of the stabilizer engaging the circuit board; and
wherein rotation of the electrical base in a second direction causes the stabilizer to be positioned in a disengaged position defined as the stabilizer being translatable longitudinally relative to the body member such that the engaging member of the stabilizer disengages the circuit board.

16. The lighting device of claim 15 wherein the stabilizer is substantially cylindrical.

17. The lighting device of claim 15 wherein the optic comprises a top section and a bottom section.

18. A lighting device comprising:
an electrical base;
a stabilizer threadably connected to the electrical base;
a body member positioned in thermal communication with the stabilizer;
an optic connected to the body member and defining an optical chamber; and
a light source positioned within the optical chamber, in thermal communication with the body member, and in electrical communication with the electrical base;
a spacer positioned between the electrical base and the body member adjacent to an intermediate portion of the stabilizer;
wherein the stabilizer is transitionable between an engaged position and a disengaged position;
wherein the disengaged position is defined as the stabilizer being translatable longitudinally with respect to the body member; and
wherein the engaged position is defined as the stabilizer being moveably fixed with respect to the body member.

19. The lighting device of claim 18 wherein the light source comprises a circuit board and a plurality of LEDs that are circumferentially positioned on the circuit board.

20. The lighting device of claim 19 wherein the circuit board comprises an aperture formed therein along a medial portion thereof; wherein a top portion of the stabilizer comprises an engaging member and configured to be positioned through the aperture of the circuit board; wherein the stabilizer is configured to be transitioned to the engaged position, thereby engaging the circuit board, upon rotation of the electrical base in a first direction; and wherein the stabilizer is configured to be transitioned to the disengaged position, thereby disengaging the circuit board, upon rotation of the electrical base in a second direction.
