The specific embodiment

As shown in Figure 1, the described LED Down lamp of the utility model comprises antifog circle 1, glass plate 2, face ring 3, aluminium cup 4, radiator 5 and the driver 6 that is arranged in order, wherein,

Said antifog circle 1 adopts aluminium sheet punching press system to form with said ring 3, and any surface finish can be done the multiple textured patterns that are processed into such as wire drawing, polishing;

Said glass plate 2 is done tempering and is handled, the inner surface frosted;

Said aluminium cup 4 is for aluminium sheet is stamped to form, and inner surface bottom frosted, the bright and clean processing of sidewall play the optically focused effect;

Said radiator 5 adopts 6063 aluminiums to stretch and processes, have higher thermal conductivity factor, and outer surface is through processing or evenly varnished, and quality is even, and is elegant in appearance;

During enforcement; Said radiator 5 comprises wave dentation fin and supplies the fixing heat sink of this fin; This heat sink is provided with support column, and this driver 6 is connected through this support column with this radiator 5, interval one preset distance between this wave dentation fin and the said driver 6.

The fin of said radiator is evenly distributed, forms the heat extraction passage between the adjacent fin.

Said glass plate 2 is embedded in said antifog circle 1 inside, and adopts shell fragment to fix between said antifog circle 1 and said ring 3;

Fixing between said antifog circle 1, said glass plate 2 and the said aluminium cup 4 through extruding;
