A kind of closed radiating piece, including：

For absorbing heat and supporting the upper surface of LED lamp panel, for externally distributing the lateral surface of heat and be arranged at scattered The medial surface in warmware center, the medial surface combine to form an air passage for air circulation with the upper surface；

An open lower surface is further included, the top surface edge is connected with lateral surface, and the upper face center is set It puts there are one through hole, the through hole is recessed inwardly, is connected with medial surface, and lateral surface and medial surface both encompass side wall closing Cyclic structure, form the open lower surface compared with the opposite side of upper surface for lateral surface and medial surface.

Further, multiple supporting points for being used to support LED lamp panel are provided on the upper surface, the supporting point is distributed in Upper surface and lateral surface, the surface of medial surface composition, the surface not only have supporting role, are additionally operable to contact with heater, Transfer heat to two sides.

Further, the upper surface and the junction of lateral surface are smoothly connected to be arc-shaped, the upper surface and inside The junction in face is smoothly connected to be arc-shaped.

Further, the upper and lower surface is circular ring shape, and the lateral surface and medial surface are three-dimensional circular ring shape.

The beneficial effects of the utility model are：LED lamp panel where LED luminescence units is contacted directly with radiating piece, heat Lateral surface and medial surface are transferred to by upper surface, form convection current using temperature difference, hot-air passes through the air that is made of medial surface Convection channel and extraneous exchange of cold air, heat is effectively taken away, prevents hot stack inside LED lamp, extend the LED light longevity Life.
