The present invention provides a novel cup-shaped heat dissipater structure for meeting the heat dissipation requirement of an electric luminous body; the outer cup bottom of the cup-shaped heat dissipater (100) is formed as a planar or convex or concave surface for accommodating the electric luminous body (200), so the heat generated by the electric luminous body (200) can be dissipated to the exterior from the surface of the heat dissipater, with the enlarged inner recessed surface formed on the cup-shaped structure in the heat dissipater (100) opposite to the installation location of the electric luminous body (200), the heat inside the heat dissipater (100) can also be directly dissipated through the larger heat dissipation area formed on the inner recessed surface of the cup-shaped structure, thereby assisting the electric luminous body (200) to dissipate heat to the exterior.
