Abstract
The invention provides a light-emitting diode illumination apparatus. The light-emitting diode illumination apparatus includes a tube, a chamber, a porous capillary diversion layer, at least one heat-dissipating fin, and a diode light-emitting module. The tube has a first opening. The chamber has a second opening and a flat end. The second opening is engaged to the first opening. The porous capillary diversion layer is formed in the tube and the chamber. The tube and the chamber form a sealed space. The sealed space accommodates a working fluid. A section area of the chamber is larger than a section area of the tube. The at least one heat-dissipating fin is disposed on a circumference of the tube. The diode light-emitting module is disposed on the flat end.
