The lamp plate erecting bed is formed on the inner sleeve top of described radiator, case erecting bed and screw hole are formed on the top of dowel, the LED lamp plate is arranged on the lamp plate erecting bed, the convex wall below of lower encioser lower end snaps onto on the case erecting bed of radiator, trim ring is fixed top at radiator by screw and screw hole, and the inner ring of trim ring is pressed on the LED lamp plate and the outer ring is pressed on the convex wall of lower encioser.

After adopting such scheme, the utility model is because set up the resin loam cake, and the structure of radiator improved, so formed upper air vent, ventilating duct and lower air vent for circulation of air, the outer wall of radiator inner sleeve and inwall, the outer wall of overcoat all can be dispelled the heat, utilize that three heat radiations reach fully, the timely splendid radiating effect of heat radiation, thereby be conducive to prolong the service life of LED lamp.

In addition, utilize trim ring fixedly lower encioser and LED lamp plate, the space-closed that upper encloser and lower encioser are formed can prevent effectively that winged insect from entering.

Below in conjunction with the drawings and specific embodiments the utility model is described further.
