Abstract

An LED fixture include a mask structure and an LED module. The mask structure includes a cooling fin set of buckling type, an upper socket and a lower socket. The cooling fin set is constituted by a plurality of cooling fins that are encircled and inter-buckled to each other. An interior enclosed by the cooling fin set is formed into an accommodating space and a fitting hole connecting the accommodating space. The upper socket is assembled to one side of the fitting hole, while the lower socket is assembled to another side of the fitting hole. Meanwhile, the upper socket and the lower socket are respectively fastened by the cooling fin set through a clipping-and-abutting manner. The LED module is arranged by accommodating in the accommodating space and is connected to the cooling fin set as well. Accordingly, the entirely cooling effectiveness is promoted and the using lifetime is prolonged.

Claims
