THERMO-OPTICAL ENCLOSURE FOR LED LIGHTING APPLICATIONS

摘要

The invention provides a lamp (1) comprising (i) a solid state light source (10) and a first envelope (100) at least partially enclosing the light source (10), thereby forming a first cavity (150) hosting said solid state light source (10), wherein at least part of the first envelope (100) is transmissive for visible light (11) generated by the solid state light source (10); and (ii) a second envelope (200) at least partially enclosing the first envelope (100), wherein the first envelope (100) and the second envelope (200) provide a second cavity (250) at least partially enclosing the light source (10), wherein at least part of the second envelope (200) is transmissive for visible light (11) generated by the light source (10) and transmitted through the first envelope (100) into the second cavity (250), wherein the second cavity (250) is configured as a heat pipe (251).
