The invention provides a light-emitting diode illuminating apparatus. The light-emitting diode illuminating apparatus includes a carrier, a substrate, a light-emitting diode chip, a heat-conducting device, and a thermal phase-change material. The carrier includes a top surface and a bottom surface. A first recess is formed on the top surface of the carrier. A second recess is formed on the bottom surface of the carrier. The first recess communicates with the second recess. The substrate is embedded into the second recess. The light-emitting diode chip is disposed on the substrate. The heat-conducting device includes a flat part. And, the substrate is disposed on the flat part. |
