The present application claims priority to and is a continuation under 35 U.S.C. §120 of U.S. Non-provisional patent application Ser. No. 13/683,594 filed on Nov. 21, 2012, which claims priority under 35 U.S.C. §120 of U.S. Non-provisional patent application Ser. No. 12/599,500 filed on Nov. 9, 2009, which claims priority under 35 U.S.C. §371 to International Patent Application No. PCT/US2008/064168 filed May 19, 2008 and further claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 60/939,275, filed on May 21, 2007. The entire contents of each of the above identified priority documents are hereby incorporated herein by reference. The present application is related to U.S. Non-provisional patent application Ser. No. 11/711,218, filed on Feb. 26, 2007; U.S. Provisional Patent Application No. 60/777,310, filed on Feb. 27, 2006; U.S. Provisional Patent Application No. 60/838,035, filed on Aug. 15, 2006; and U.S. Provisional Patent Application No. 60/861,789, filed on Nov. 29, 2006. The entire contents of each of the above identified related patent applications are hereby incorporated herein by reference.
an optic that is disposed at the substrate and that comprises a refracting exterior surface and a refracting inner surface forming a cavity; and
a light emitting diode source disposed at the substrate to emit light that illuminates the cavity and that includes rays traveling along the substrate at an orientation that would miss the refracting exterior surface, wherein the refracting inner surface is configured to reorient said rays for incidence on said refracting exterior surface.
2. The lighting system of claim 1, wherein the light emitting diode comprises a dome.
3. The lighting system of claim 1, wherein the refracting inner surface comprises a flared skirt.
4. The lighting system of claim 1, wherein the optic is mounted in a well.
5. The lighting system of claim 1, comprising a carrier disposed adjacent the optic.
6. The lighting system of claim 1, wherein a light emitting diode package comprises the light emitting diode source.
a light emitting diode source disposed at the substrate to emit light that comprises rays oriented adjacent and substantially parallel to the substrate; and
an optic comprising an exterior surface and an interior surface that defines a cavity facing the light emitting diode source, wherein the interior surface is configured to redirect said rays outward with respect to the substrate.
8. The lighting device of claim 7, wherein said rays are radiated at 90 degrees from a centerline of the light emitting diode source.
9. The lighting device of claim 7, wherein the light emitting diode source comprises a vertical centerline, and
wherein said rays are oriented at approximately 90 degrees relative to the vertical centerline.
10. The lighting device of claim 7, wherein a light emitting diode package comprises the light emitting diode source and a dome, and
wherein the dome is disposed in the cavity.
11. The lighting device of claim 7, wherein the light emitting diode source comprises a light emitting diode package that is disposed in a well of a carrier.
12. The lighting device of claim 7, wherein the interior surface comprises a flared skirt.
13. The lighting device of claim 7, wherein the interior surface comprises a refracting surface.
a surface extending outwards from the substrate;
an optic attached to the substrate adjacent the surface, the optic comprising an outer surface and an inner surface forming a cavity; and
an LED source disposed at least partially in the cavity so as to produce light rays propagating along the substrate in an orientation for impingement on the surface,
wherein the inner surface comprises a region that is operative to redirect said light rays away from the substrate to avoid said impingement on the surface.
15. The lighting device of claim 14, wherein the surface comprises an interior wall.
16. The lighting device of claim 14, wherein a well comprises the surface.
17. The lighting device of claim 14, wherein the LED source comprises a vertical centerline, and
18. The lighting device of claim 14, wherein an LED package comprises the LED source.
19. The lighting device of claim 14, wherein the inner surface comprises a flared skirt.
20. The lighting device of claim 14, comprising a carrier disposed adjacent the optic.
