Patent ID: 7722217

Claim:
A light-emitting diode cluster lamp, comprising: a plurality of light-emitting diode lamp packages, each of the light-emitting diode lamp packages comprising: a heat-conducting and dissipating module, comprising: a heat-conducting device having a chamber surrounded by a flat end portion and a cylindrical wall sealed to a peripheral of the flat end portion, wherein a capillary structure is formed on both the inner surface of the flat end portion and the inner surface of the cylindrical wall, a work fluid being distributed in the capillary structure and evaporated at the flat end portion; and at least one heat-dissipating fin mounted on the circumference of the heat-conducting device; and a light-emitting diode module disposed on the flat end portion of the heat-conducting device; and a control circuit module for controlling the light-emitting diode lamp packages; wherein when the light-emitting diode cluster lamp is connected to a power source, the control circuit module selectively controls the light-emitting diode modules to emit light, and the heat generated during light emission of one of the light-emitting diode modules is conducted from the flat end portion of the heat-conducting device corresponding to the one light-emitting diode module to the at least one heat-dissipating fin, and then dissipated by the at least one heat-dissipating fin, wherein each flat end portion of the heat-conducting device is substantially parallel to each other such that the direction of the major portion of the light generated from each light-emitting diode module is substantially parallel to each other.
