Abstract:
A New Phosphor-converted LED Device (“NPCLD”) is disclosed. The NPCLD may include a lens over a phosphor body, in which the lens and the phosphor body each have a substantially convex upper surface. The NPCLD may alternatively include first and second lenses, the first lens having a substantially flat interface with a phosphor body.
