LED ring assembly
View Patent ↗Disclosed is a lighting device that includes a heat sink coupled to a heat dissipation structure. The heat dissipation structure can include heat conduits operatively coupled to the LED to receive and emit heat from the LED. The heat conduits conduct heat from the LED to the heat sink that is distally disposed relative to the LED to protect the internal components of the lighting device.
1. A lighting device comprising:
a housing adapted to house a light emitting structure;
a reflector disposed within the housing and adapted to reflect light emitted from the light emitting structure; and
a heat dissipation structure coupled to the housing and defining an opening, the heat dissipation structure including:
a heat conduit operatively coupled to the light emitting structure to receive heat therefrom; and
a heat sink provided in the opening and operatively coupled to the heat conduit to receive the heat and dissipate the heat away from the light emitting device.
2. The lighting device according to claim 1 , wherein the light emitting structure is a light emitting diode (LED).
3. The lighting device according to claim 1 , further comprising a lens adapted to focus light reflected by the reflector.
4. The lighting device according to claim 3 , further comprising upper and lower gaskets respectively disposed above and below the lens.
5. The lighting device according to claim 1 , wherein the housing includes a first housing portion coupled to a second housing portion.
6. The lighting device according to claim 1 , wherein the heat dissipation structure further includes a cap, a body, and an extension portion coupling the cap to the body, and wherein the heat conduit extends from the cap to the body.
7. The lighting device according to claim 6 , wherein the light emitting structure is coupled to the heat dissipation structure at the cap.
8. The lighting device according to claim 6 , wherein the heat conduit includes a linear portion and an angled portion extending from the linear portion at an angle.
9. The lighting device according to claim 8 , wherein the linear portion is disposed proximate the light emitting structure and the angled portion is disposed proximate the heat sink.
10. The lighting device according to claim 6 , further comprising a cover adapted to house the heat conduit within the heat dissipation structure.
11. The lighting device according to claim 1 , wherein heat dissipation structure further includes a groove adapted to receive the heat conduit.

a cap;
an extension portion extending from the cap;
a body extending from the extension portion;
a heat conduit operatively coupled to the light emitting device and adapted to transfer heat away from the light emitting device;
a heat sink operatively coupled to the heat conduit and adapted to receive the heat from the heat conduit and dispense the heat away from the heat dissipation structure; and
a heat dissipation structure defining
an opening adapted to receive the heat sink.
13. The heat dissipation structure according to claim 12 , further comprising a groove adapted to receive the heat conduit.
14. The heat dissipation structure according to claim 12 , wherein the heat conduit includes a linear portion and an angled portion extending from the linear portion at an angle.
15. The heat dissipation structure according to claim 14 , wherein the linear portion is disposed proximate the light emitting structure and the angled portion is disposed proximate the heat sink.
16. The heat dissipation structure according to claim 12 , further comprising a cover adapted to house the heat conduit.
