Abstract
A light-emitting diode package is described comprising a body including a hollow having a rim that extends outwardly from an open end of the hollow. A light emitting diode is positioned in the hollow and opposite the open end. A nongaseous transparent optical medium fills the hollow and a phosphor-containing element (PCE) is disposed over the hollow sealing the open end. The PCE has a solid body and a lateral portion including a periphery and dividing a top and a bottom. The bottom of the PCE is convex and in contact with the nongaseous transparent optical medium and the periphery of the PCE is in contact with the rim.
Claims12
A light-emitting diode package comprising:
- a body including a hollow having a rim, said rim extending outwardly from an open end of said hollow;
- a light emitting diode positioned in said hollow and opposite said open end;
- a nongaseous transparent optical medium filling said hollow;
- and
- a phosphor-containing element (PCE) disposed over said hollow and sealing said open end, said PCE having a solid body and a lateral portion including a periphery dividing a top and a bottom, said bottom being convex and in contact with said nongaseous transparent optical medium and said periphery being in contact with said rim and including at least one venting aperture.
A light source comprising:
- an array of light emitting diodes;
- each light emitting diode being positioned in a hollow having an outwardly extending rim;
- a plurality of phosphor-containing elements (PCE), each PCE disposed above a respective light emitting diode;
- a nongaseous transparent optical medium disposed between each PCE and its respective light emitting diode;
- said PCEs comprising:
- a solid body having a lateral portion dividing a top and a bottom, said bottom being convex, said lateral portion having a periphery, said bottom being in contact with said nongaseous transparent optical medium and said periphery being in contact with said rim;
- and
- wherein said light emitting diodes are disposed in bins in a compartmentalized container.
