Embedded LED light source
A light source is disclosed. For example, the light source includes an enclosure forming an internal volume, the enclosure having at least one side, a top and a bottom. At least one light emitting diode (LED) may be deployed within the internal volume of the enclosure. Optionally, an optic may be coupled to each one of the at least one LEDs. The light source also includes a potting compound surrounding said at least one LED and substantially filling said internal volume or covering said top of said enclosure and substantially sealing said enclosure.
1. A light source, comprising:
an enclosure forming an internal volume, said enclosure having at least one side, a top and a bottom;
at least one light emitting diode (LED) deployed within said internal volume of said enclosure;
a potting compound surrounding said at least one LED and substantially filling said internal volume, wherein the potting compound provides a barrier between the at least one LED and a flammable atmosphere;
a plurality of heat sink fins coupled to an exterior side of said enclosure opposing said at least one LED and in direct contact with an atmosphere external to said enclosure; and
at least one power supply coupled to said enclosure to power said at least one LED with a constant current, wherein said at least one power supply forms a side of the enclosure and is sealed with said potting compound.
2. The light source of claim 1 , wherein said top comprises a clear plate.
3. The light source of claim 2 , wherein said clear protective plate is fabricated from glass or plastic.
4. The light source of claim 1 , wherein said potting compound is clear.
5. The light source of claim 4 , wherein said potting compound comprises at least one of a silicone, acrylic, epoxy or urethane based material.
6. The light source of claim 5 , wherein said silicone elastomer comprises at least one of Sylgard 182 or Sylgard 184.
7. The light source of claim 1 , wherein said at least one LED comprises at least one array of LEDs and said at least one power supply comprises a plurality of power supplies wherein at least one power supply is used to power each of said at least one array of LEDs.
8. The light source of claim 1 , wherein said enclosure is fabricated from aluminum.
9. A light source, comprising:
an enclosure forming an internal volume, said enclosure having at least one side, a top and a bottom;
at least one light emitting diode (LED) deployed within said internal volume of said enclosure;
a potting compound covering an exterior side of said top of said enclosure and substantially sealing said enclosure, wherein said internal volume of said enclosure is substantially free of said potting compound to create an air-LED interface, wherein the potting compound provides a barrier between the at least one LED and a flammable atmosphere;
a plurality of heat sink fins coupled to said enclosure opposing said at least one LED and in direct contact with an atmosphere external to said enclosure; and
at least one power supply coupled to said enclosure to power said at least one LED with a constant current, wherein said at least one power supply forms a side of the enclosure and is sealed with said potting compound.
10. The light source of claim 9 , wherein said internal volume is substantially filled with air.
11. The light source of claim 9 , wherein said top comprises a clear plate fabricated from glass or plastic.
12. The light source of claim 9 , wherein said potting compound comprises at least one of a silicone, acrylic, epoxy or urethane based material.
13. A light source, comprising:
an enclosure forming an internal volume, said enclosure having at least one side, a top and a bottom;
at least one light emitting diode (LED) deployed within said internal volume of said enclosure;
an optic coupled to each one of said at least one LED;
a potting compound surrounding said at least one LED and said optic coupled to said at least one LED and substantially filling said internal volume, wherein the potting compound provides a barrier between the at least one LED and a flammable atmosphere;
a plurality of heat sink fins coupled to said enclosure opposing said at least one LED and in direct contact with an atmosphere external to said enclosure; and
at least one power supply coupled to said enclosure to power said at least one LED with a constant current, wherein said at least one power supply forms a side of the enclosure and is sealed with said potting compound.
14. The light source of claim 13 , wherein said optic comprises a reflector.
15. The light source of claim 13 , wherein said optic comprises a lens.
16. The light source of claim 13 , wherein said top comprises a clear plate fabricated from glass or plastic.
17. The light source of claim 13 , wherein said potting compound comprises at least one of a silicone, acrylic, epoxy or urethane based material.
