Above-mentioned lamp efficient radiating apparatus, wherein: following radiator 10 is provided with spiral airflow hole 11, its side is by some hollow heat radiations chamber B12 looping, heat radiation chamber B12 lateral surface is provided with some fin B13, following radiator end face is provided with eight joint pins 14, and correspondence snaps in isolates among six cable via holes 8 of middle cover and four the connecting hole B9; Following radiator 1 bottom surface is provided with two cold airs and enters hole C15, four louvre C16 and four connecting hole C17, and cold air enters hole C15, louvre C16 all can be used as the cable via hole.

The utility model compared with prior art as can be known from the above technical solutions, last radiator, is isolated middle cover and hollow heat radiation chamber A, the hollow heat radiation chamber B in the radiator and the design of fin down. and increase the heat space of dispersing, strengthen area of dissipation; With the original plastic casing of metal substitute, make its heat conduction, radiating rate faster; The distance of fluorescent tube and wiring board is elongated, isolate heat and the transmission of fluorescent tube outside heat that the design of middle cover has avoided wiring board to produce, alleviated being subjected to heat load and increasing service life of lamp of wiring board electronic component; Can break down wiring board, electronic component blast, the spark that short circuit produced is fixed in the lamp housing, thereby prolongs lamp service life.

Below further specify the beneficial effects of the utility model by the specific embodiment.

The specific embodiment

Embodiment 1:

Referring to Fig. 1-3, the lamp efficient radiating apparatus, its structure is: radiator 1 on the column of hollow, and its side is by some hollow heat radiations chamber A2 looping, and heat radiation chamber A2 lateral surface is provided with some fin A3; Last radiator 1 end face is provided with two cold airs and enters hole A4, four louvre A5 and four connecting hole A6, and cold air enters hole A4, louvre A5 all can be used as the cable via hole; Isolation middle cover 7 is fixed on the radiator 1 by joint pin and forms cavity with last radiator 1 bottom surface, is beneficial to heat radiation.Isolate middle cover 7 and be provided with six cable via holes 8 and four connecting hole B9.

Embodiment 2:

Referring to Fig. 1-6, following radiator 10 is provided with spiral airflow hole 11, its side is by some hollow heat radiations chamber B12 looping, heat radiation chamber B12 lateral surface is provided with some fin B13, following radiator end face is provided with eight joint pins 14, and correspondence snaps in isolates among six cable via holes 8 of middle cover and four the connecting hole B9; Following radiator 1 bottom surface is provided with two cold airs and enters hole C15, four louvre C16 and four connecting hole C17, and cold air enters hole C15, louvre C16 all can be used as the cable via hole; All the other are with embodiment 1.

Make use-case 1:
