Heat sink apparatus for solid state lights
View Patent ↗Embodiments of the current invention seek to increase heat dissipation by affixing a separate or integrated heat sink to the solid state light, thus accomplishing increased heat dissipation via another device, instead of altering the solid state light itself. In this manner, embodiments of the invention increase the amount of heat dissipated from solid state lights without requiring any redesign of the solid state lights themselves.
1. A heat sink apparatus for a solid state light, comprising:
a heat sink comprising:
a first end integrally formed with the solid state light;
a second end opposite the first end; and
a heat dissipating portion between the first end and the second end;
wherein the heat dissipating portion has an elongated portion and a plurality of fins for dissipating heat generated by the solid state light, the fins extending from the elongated portion.
2. The heat sink apparatus of claim 1 , further comprising a sleeve extending from the second end and surrounding the fins.
3. The heat sink apparatus of claim 1 , wherein the second end further comprises a base that is a screw, bayonet or bi-pin base, the base configured to be threaded into an electrical socket.
4. The heat sink apparatus of claim 1 , wherein each fin of the plurality of fins extends radially from the elongated portion.
5. The heat sink apparatus of claim 1 , wherein each fin of the plurality of fins extends circumferentially from the elongated portion.
6. The heat sink apparatus of claim 1 , further comprising a driver for the solid state light, the driver in electrical communication with the first end and configured to supply power to the solid state light.
7. The heat sink apparatus of claim 6 , wherein the driver is proximate to the second end.
8. The heat sink apparatus of claim 6 , wherein the driver is remote from the heat sink.
9. The heat sink apparatus of claim 1 , wherein the solid state light is a LED light.
10. A solid state light assembly, comprising:
a solid state light; and
a heat sink integrally affixed to the solid state light, the heat sink comprising at least one fin for dissipating heat generated by the solid state light.
11. The solid state light assembly of claim 10 , wherein the heat sink has a first end and an opposite second end, wherein the solid state light is affixed to the first end, and wherein the second end has a lamp base for connection to an electrical socket.
12. The heat sink apparatus of claim 11 , wherein the lamp base is at least one of a screw base, a bayonet base, and a bi-pin base.
13. The solid state light assembly of claim 10 , wherein each fin of the at least one fin extends generally radially from the heat sink.
14. The solid state light assembly of claim 10 , wherein each fin of the at least one fin extends generally circumferentially from the heat sink.
