| 1. A New Phosphor-Converted LED Device (“NPCLD”), comprising:
a concave base housing;
a light emitting diode (“LED”) in the concave base housing, the LED having a p-doped semiconductor body and an n-doped semiconductor
body;
a phosphor body over the LED, the phosphor body having a substantially flat upper surface;
a first lens over the LED, the first lens having a substantially flat upper surface; and
a second lens over the phosphor body and over the first lens, the second lens having a substantially convex upper surface;
and
the first lens and the phosphor body together having a substantially flat interface.
