The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figures 1 to 4, a kind of LED lamp 100 with annular cell-shell structure that the utility model relates to, comprise lamp holder 1, driver (not shown), radiator 2, led light source assembly 3 and outer cover 4, this lamp holder 1 is used for linking to each other with power supply, this driver is arranged between lamp holder 1 and the led light source assembly 3, and the heat that this radiator 2 is used for led light source assembly 3 courses of work are produced distributes.
Main improvements of the present utility model are: be formed with perforation 421 on this outer cover 4, the heat-dissipating casing 22 that this radiator 2 has heat sink 21 and links to each other with heat sink 21, this led light source assembly 3 is arranged on the heat sink 21, also is provided with the column 23 that runs through this perforation 421 on this heat sink 21.Like this, this column 23 can contact with ambient atmosphere, and then improves the radiating effect of entire radiator 2.In the present embodiment, this heat sink 21 is aluminium base.
Preferably, see also Fig. 2 and shown in Figure 3, this column 23 is formed with passage 231, and this passage 231 specifically is formed on column 23 outer surfaces, and is a plurality of; This heat-dissipating casing 22 has a plurality of hollow holes 221, and this passage 231 runs through the upper and lower surface of whole aluminium base and communicates with a plurality of hollow hole 221 air-flows.So cold air can be passed to the following side space of led light source assembly 3 again by passage 231, discharges from a plurality of hollow holes 221 at last, has namely formed the circulatory system of a cold and hot air, has strengthened the radiating effect of whole lamp greatly.
