Abstract:
1. A system-in-package, highly efficient and high power light-emitting diode lamp, comprising: a light-guiding device having a first end and a second end; and a first packaged system, mounted on the first end of the light-guiding device, comprising: a first heat conducting/dissipating module, comprising a first heat pipe with a flat top end and a periphery wall; at least one first heat-dissipating fin, being mounted on the periphery wall of the first heat pipe; a first diode light-emitting device, mounted only on the flat top end of the first heat pipe and capable of being electrically connected to a power supply, for converting a first electric energy supplied by the power supply into a first light; wherein when the first diode light-emitting device emits the first light, the first light enters into the light-guiding device approximately parallel to the first heat pipe and the heat generated during the light-emitting of the first diode light-emitting device is conducted by the first heat pipe from the flat top end thereof to the at least one first heat-dissipating fin, and then is dissipated by the at least one first heat-dissipating fin; and a first sleeve, one end of the first sleeve being adapted for the insertion of the first diode light-emitting device, and the other end of the first sleeve being adapted for the insertion of the first end of the light-guiding device; wherein the first diode light-emitting device comprises a first substrate, a first light-emitting module disposed on the first substrate, and two first electrodes disposed on the first substrate, the first substrate is only mounted on the flat top end of the first heat pipe; and a second packaged system, mounted on the second end of the light-guiding device, comprising: a second heat conducting/dissipating module, comprising a second heat pipe with a flat top end and a periphery wall; at least one second heat-dissipating fin being mounted on a the periphery wall of the second heat pipe; a second diode light-emitting device, mounted only on the flat top end of the second heat pipe and capable of being electrically connected to the power supply, for converting a second electric energy supplied by the power supply into a second light; wherein when the second diode light-emitting device emits the second light, the second light enters into the light-guiding device approximately parallel to the second heat pipe, and the heat generated during the light-emitting of the second diode light-emitting device is conducted by the second heat pipe from the flat top end thereof to the at least one second heat-dissipating fin, and then is dissipated by the at least one second heat-dissipating fin; and a second sleeve, one end of the second sleeve being adapted for the insertion of the second diode light-emitting device, and the other end of the second sleeve being adapted for the insertion of the second end of the light-guiding device; wherein the second diode light-emitting device comprises a second substrate, a second light-emitting module disposed on the second substrate, and two second electrodes disposed on the second substrate, the second substrate is only mounted on the fiat top end of the second heat pipe.
