Abstract
An LED illuminating device includes an optical section, an electrical section, and a heat dissipation section. The heat dissipation section is provided with a loop heat exchange device. The loop heat exchange device includes a hollow metal base and a plurality of metal fins extending outwardly from the metal base. A hermetical chamber is defined in the metal base. The chamber is cylindrical and has a U-shaped cross section along an axial direction of the metal base. A wick structure is attached to an inner surface of the chamber. A working fluid is saturated in the wick structure. A light source is thermally attached to the metal base.
