The present invention provides an illuminating device and heat-dissipating structure thereof. The heat-dissipating structure includes at least one thermally conductive element (51) and a plurality of heat-dissipating units stacked together. Each heat-dissipating unit includes a cone-like fin (11) with an opening (12) and a plurality of protrusions (13) 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 (52) to constitute the illuminating device. |
