Abstract: The present invention provides an illuminating device and heat-dissipating structure thereof. The heat-dissipating structure includes a plurality of heat-dissipating units stacked together. Each heat-dissipating unit includes a cone-like portion with an opening and a plurality of protrusions connected to the cone-like portion, wherein at least one of the protrusions of one heat-dissipating unit is coupled to that of the adjacent heat-dissipating unit to form one or more zonal planes for allowing a light source to be disposed thereon to constitute the illuminating device, and the openings of the heat-dissipating units are liked together to form an airflow passage.

Abstract: The present invention provides an illuminating device and heat-dissipating structure thereof. The heat-dissipating structure includes at least one thermally conductive element and a plurality of heat-dissipating units stacked together. Each heat-dissipating unit includes a cone-like fin with an opening and a plurality of protrusions connected to the cone-like fin, wherein at least one of the protrusions of one heat-dissipating unit is coupled to that of the adjacent heat-dissipating unit to form one or more zonal planes for allowing one end of the thermally conductive element to be disposed thereon, and the other end of the thermally conductive element is connected with a heat source to constitute the illuminating device.
