PURPOSE: A high efficient light emitting diode-based illuminating apparatus is provided to effectively emit heat generated from a light emitting diode-based light source part by connecting a first connecting part and a second connecting part. CONSTITUTION: A high efficient light emitting diode-based illuminating apparatus includes a first heat pipe(100), a second heat pipe, a light emitting diode-based light source part(120), a heat emitting part(140), and a reflecting cap(160). The apparatus further includes a heat transferring part. The first heat pipe and the second heat pipe are cylindrical. The first heat pipe and the second heat pipe are integrated. The light emitting diode-based light source part is composed of a plurality of light emitting diode elements arranged on one cross section and the outer circumference of the first heat pipe. The heat emitting part is arranged at the outer circumference of the second heat pipe. The reflecting cap is arranged between the light emitting diode-based light source part and the heat emitting part. |
