  • Patent number: 7467882
    Abstract: The present invention discloses a LED (Light-Emitting Diode) heat-dissipating module, which comprises a heat-dissipating fin, a heat-conduction pipe, a LED illumination module and a casing. The heat-dissipating fin has an insertion/press-fit member inserted by or press-fitted to the heat-conduction pipe. The heat-conduction pipe has a contact region contacting the LED illumination module. In the application of the present invention, the LED illumination module is installed on the contact regions of several heat-conduction pipes inserted into or press-fitted to the heat-dissipating fins; thus, the heat generated by the LED illumination module can be effectively dissipated. Then, the LED illumination module is placed inside the casing having an accommodation space. Thus, heat can be conducted via the heat-conduction pipe to the heat-dissipating fin and then fast dissipated therefrom even though the LED illumination module is placed inside the casing.

  • Publication number: 20080246383
    Abstract: The present invention discloses an LED-lamp heat-dissipation device, which comprises LED lamps, an aluminum baseplate and a hollow heat-dissipation module. The hollow heat-dissipation module further comprises a hollow accommodation unit and a cooling fin unit, and the hollow accommodation unit has a plurality of heat-dissipation strips. The LED lamps are soldered on the aluminum baseplate. The aluminum baseplate together with the LED lamps is applied onto one side of the hollow heat-dissipation module; then liquid is filled into the hollow accommodation unit of the hollow heat-dissipation module. When the LED lamps are turned on, heat will be conducted to the aluminum baseplate and then conducted to the cooling fin unit via the liquid inside the hollow accommodation unit, which the aluminum baseplate is applied onto. Then, the cooling fin unit will dissipate heat out. Thereby, the present invention can achieve a fast heat-dissipation effect.
