Abstract

A lighting device includes an outer body having a base, a medial portion, and an upper portion. The lighting device may also include a light source carrying assembly to carry a light source and a lens. The light source carrying assembly may include an assembly base, an assembly top that pivotally engages a portion of the assembly base, and a heat sink. The light source carrying assembly may be configured to rotate about a first rotational axis and to pivot about a second rotational axis.

Claims

1. A lighting device comprising:

an outer body comprising a base, a medial portion, and an upper portion;

a light source carrying assembly carrying a rotatable first light source, the light source carrying assembly comprising;

an assembly base that is carried by the medial portion of the outer body,

an assembly top comprising a bottom portion, sidewalls and a top portion, the bottom portion of the assembly top including an assembly base connector member that pivotally engages a portion of the assembly base,

a heat sink that matingly engages a portion of the assembly top, and

a lens carried by the assembly top; and

a non-rotatable second light source carried by the outer body that is annularly o d around the rotatable first light source;

wherein the light source carrying assembly is configured to rotate in relation to the outer body about a first rotational axis defined by a vertical axis of the lighting device that passes through a medial portion of the base of the outer body;

wherein the light source carrying assembly and the first light source are configured to pivot about a second rotational axis defined by a horizontal axis passing through a medial portion of the assembly base connector member of the assembly top;

wherein the outer body generally circumscribes the light source carrying assembly; and

wherein the first and second rotational axes are perpendicular to one another.

2. A lighting device according to claim 1 further comprising a rotation mechanism configured to rotate the light source carrying assembly about at least one of the first and second rotational axes.

3. A lighting device according to claim 2 wherein the rotation mechanism is a first rotation mechanism configured to rotate the light source carrying assembly about the first rotational axis, and a second rotation mechanism configured to rotate the light source carrying member about the second rotational axis.

4. A lighting device according to claim 3 wherein the first and second rotation mechanisms are selected from the group consisting of an AC motor, a DC motor, an electrostatic motor, a servo motor, a stepper motor, an actuator, a hydraulic motor, a pneumatic motor, an electromagnet, and a permanent magnet.

5. A lighting device according to claim 1 wherein the light source is positionable such that light emitted by the light source propagates substantially below a plane defined by a surface portion of the upper portion of the outer body.

6. A lighting device according to claim 1 wherein the light source is configured to emit light in at least one of a first and second beam angle;

and wherein the second light source is configured to emit light in the second beam angle.

7. A lighting device according to claim 1 further comprising a channeling device so that the light emitted from the second light source is directed to the lens.

8. A lighting device according to claim 1 wherein the base of the outer body is selected from the group consisting of an Edison base, a bayonet base, a double contact bayonet base, a bi-pin, a bi-post, a wedge, and a GU10 turn and lock base.

9. A lighting device according to claim 1 wherein the light source comprises a light emitting diode (LED).

10. A lighting device comprising:

a light source carrying assembly carrying a rotatable first light source, the light source carrying assembly comprising;

an assembly base,

an assembly top that rotationally engages a portion of the assembly base, and

an outer body generally circumscribing the light source carrying assembly and comprising a base, an upper portion, and a plurality of ribs and carrying a non-rotatable second light source carried by the outer body, that is annulary formed around the rotatable first light source;

a driver circuit; and

a channeling device;

wherein the driver circuit is electrically coupled to at least one of the rotatable first light source, the non-rotatable second light source, and the base;

wherein the rotatable first light source is configured to emit light in at least one of a first and second beam angle;

wherein the second light source is configured to emit light in the second beam angle;

wherein the light generated from the second light source is directed to the lens by the channeling device, and

wherein the plurality of ribs carries the channeling device.

11. A lighting device according to claim 10 wherein the second light source is carried by at least one of the outer body in a position generally towards the base relative to the light source and the light source carrying assembly adjacent the light source;

and wherein the channeling device is configured to direct light emitted by the second light source so as not to be incident upon the light source.

12. A lighting device according to claim 10 wherein the channeling device is configured to direct light emitted by the second light source to an area adjacent an outer edge of the light source.

13. A lighting device according to claim 12 wherein the channeling device is configured to direct light emitted by the second light source so as to be emitted generally annularly about the light source.

14. A lighting device according to claim 10 wherein the light emitted by the light source and the second light source combines to form a combined light;

wherein the combined light has a center beam and a gradient; and

wherein the center beam has a greater brightness than the gradient.

15. A lighting device according to claim 10 further comprising a second driver circuit electrically coupled to at least one of the second light source, the driver circuit, and a communication device.

16. A lighting device according to claim 10 further comprising a communication device.

17. A lighting device according to claim 16 wherein the communication device is electrically coupled to at least one of the driver circuit and a rotation mechanism.

18. A lighting device according to claim 16 wherein the communication device is a wireless communication device.

19. A lighting device according to claim 16 wherein the communication device is selected from the group of communication devices consisting of radio devices, computer network devices, visible light devices, and acoustic devices.
