To achieve the above object, technical solution of the present utility model is：

The utility model is a kind of improved structure of lighting apparatus radiating fin, including the first radiating fin, the second radiating Fin and the 3rd radiating fin；The first described radiating fin is made up of the first noumenon and multiple first heat sink strips, and multiple first Heat sink strip horizontally outward extends and is symmetrical arranged from the both sides of the first noumenon respectively；The second described radiating fin is by the second body With multiple second heat sink strips composition, multiple second heat sink strips stretch out and symmetrically obliquely downwards from the both sides of the second body respectively Set；The 3rd described radiating fin is made up of the 3rd body and multiple 3rd heat sink strips, and multiple 3rd heat sink strips are respectively from The both sides of three bodies stretch out and are symmetrical arranged obliquely downwards；Described the first radiating fin, the second radiating fin and the 3rd Radiating fin is sequentially fixed at together and all uses punch forming, the first heat sink strip, the second radiating fin of the first radiating fin The second heat sink strip and the 3rd radiating fin on the 3rd heat sink strip be corresponding in turn to, in the first heat sink strip, the second heat sink strip, the 3rd Vortex is formed between heat sink strip.

The angle of inclination of the 3rd heat sink strip on the 3rd described radiating fin is more than the second radiating of the second radiating fin The angle of inclination of bar.

The utility model also includes multiple radiating fins, and the plurality of radiating fin is sequentially fixed under the 3rd radiating fin Side.

The utility model is a kind of Tunnel Lamp, including street lamp mounting bracket, street lamp bonnet, street lamp panel, lamp socket, lamp source, is led Hot block and radiating fin as claimed in claim 1；The lower end of described street lamp mounting bracket, which is hinged on after street lamp, to be covered, after street lamp Cover buckle is connected on street lamp panel, and an accommodation space is formed between street lamp bonnet and street lamp panel；Described radiating fin is consolidated Dingan County is in the accommodation space that street lamp bonnet is constituted with street lamp panel, and heat-conducting block is arranged in heat-conducting block, and lamp source passes through lamp socket It is fixedly mounted on street lamp panel.

After such scheme, because the utility model includes the first radiating fin, the second radiating fin and the 3rd radiating Fin, the first radiating fin, the second radiating fin and the 3rd radiating fin all use stamping forming sheet material, lighter in weight；This Heat sink strip on the radiating fin of utility model first, the second radiating fin and the 3rd radiating fin has different gradients, can be Vortex is formed between each heat sink strip, radiating efficiency, good heat dissipation effect is substantially increased.

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Brief description of the drawings
