Light emitting diode lamp source
View Patent ↗A light fixture includes a core member having a top end, a bottom end, and a body extending between the top and bottom ends. The core member includes a solid, single member or modular members. The body includes outer surfaces (“facets”) spaced along an outer perimeter thereof. Each facet can receive one or more light emitting diode (“LED”) packages in various different positions, with different electrical and other configurations. Heat pipes extending through the core member dissipate heat from the LEDs. Active cooling modules and/or fins may assist with this heat dissipation. The heat pipes and/or a separate elongated structure extending through the core member can secure the core member to the light fixture.
1. A light fixture, comprising:
a core member comprising:
a top end;
a bottom end;
a body extending between the top end and the bottom end; and
a plurality of receiving surfaces spaced along an outer perimeter of the body, each receiving surface being operable to receive at least one light emitting diode (“LED”);
at least one LED coupled to a respective one of the receiving surfaces;
a reflector housing;
at least one wire, each wire being electrically coupled to at least one of the LEDs;
an elongated structure extending through at least a portion of the body of the core member, the elongated structure securing the core member to the reflector housing, wherein the elongated structure comprises a tubular member that provides a passageway for at least a portion of each wire; and
a heat sink positioned remotely away from the core member, wherein the heat sink is in thermal communication with the core member.
2. The light fixture of claim 1 , wherein the reflector housing comprises an interior surface, the interior surface receiving at least a portion of the light emitted from the at least one LED and reflecting the received light to a surrounding environment.
3. The light fixture of claim 1 , wherein at least one of the LEDs is mounted directly on its respective receiving surface without a substrate being disposed between the LED and the receiving surface.
4. The light fixture of claim 1 , wherein the heat sink is positioned between the reflector housing and the core member.
5. The light fixture of claim 1 , wherein the reflector housing is positioned between the heat sink and the core member.
6. The light fixture of claim 1 , further comprising a light transmitting enclosure disposed about the LED and disposed about at least a portion of the core member, wherein light emitted by the LED passes through the enclosure to a surrounding environment.
7. The light fixture of claim 6 , wherein the enclosure comprises an optical structure, the optical structure altering the light emitted by the LED.
8. The light fixture of claim 6 , wherein the enclosure comprises a phosphor coating.
