Abstract
The utility model discloses a panel lamp heat dissipation shell which comprises a cap-shaped shell. A ring body is arranged at the center of the top of the cap-shaped shell. The outer surface of the ring body protrudes and extends to form first cooling fins. A second cooling fin is arranged between every two adjacent first cooling fins and on the front portion of the outer surface of the ring body. A heat dissipation passageway between every two adjacent first cooling fins is divided into two heat dissipation passageway bodies through the corresponding second cooling fin, and the two heat dissipation passageway bodies converge on the outer surface of the ring body. Due to the structure, the feasibility of the manufacturing process is ensured under the condition that the largest density of the cooling fins is ensured, heat dissipation performance of the panel lamp heat dissipation shell is good, and the service life of an LED lamp can be greatly prolonged.

The specific embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Refer to Fig. 1 to 3, a kind of flat lamp radiation shell, comprises shape for hat housing 10, and the top center of described shape for hat housing 10 is provided with a ring body 20, and this ring body 20 is tubular structure.The center that is positioned at ring body 20 on shape for hat housing 10 offers a through hole 11, passes for holding electric wire.
The outer surface of described ring body 20 has protruded out the first radiating fin 30, between adjacent every two described the first radiating fins 30, be provided with the second radiating fin 40 in the front of described ring body 20 outer surfaces, described the second radiating fin 40 is divided into two heat dissipation channels 31 the heat dissipation channel 31 between described adjacent every two the first radiating fins 30 and comes together in the outer surface of described ring body 20.
Adjacent every two described the first radiating fins 30 are 2～3mm with the arc length of described ring body 20 joints.For traditional flat lamp radiation shell, with respect to the radiating fin (now the first radiating fin 30 and the second radiating fin 40 are referred to as radiating fin) of same density, all radiating fins collect to ring body 20, the arc length that arrives rear adjacent every two radiating fins of ring body 20 and ring body 20 joints is too small, make existing technique can not meet Production requirement, therefore general at the larger ring body 20 of the arranged outside another one diameter of ring body 20, radiating fin is only pooled on ring body 20 outer surfaces that diameter is larger.But adopt such structure to block heat dissipation channel 31, make radiating effect poor.
Described the second radiating fin 40 around described ring body 20, and is divided into two heat dissipation channels 31 by the heat dissipation channel 31 between adjacent every two the first radiating fins 30 around spread configuration.
The end 41 of the close ring body 20 of described the second radiating fin 40 forms arc structure to the outer surface bending of described shape for hat housing 10.
Between adjacent described the first radiating fin 30 and the second radiating fin 40, be provided with groove 50 in the side away from ring body 20, increased area of dissipation on the one hand, improved radiating effect; Improve on the other hand the aesthetics of this product.
On described shape for hat housing 10, be arranged with lockhole 60, for fixed flat planar lamp radiation shell.The bottom margin inner side of described shape for hat housing 10 is provided with several fasteners 70.
In sum, this device is by being provided with a ring body 20 in the top center of shape for hat housing 10, the outer surface of ring body 20 has protruded out the first radiating fin 30, between adjacent every two the first radiating fins 30, be provided with the second radiating fin 40 in the front of ring body 20 outer surfaces, the second radiating fin 40 is divided into two heat dissipation channels 31 the heat dissipation channel 31 between adjacent every two the first radiating fins 30 and comes together in the outer surface of ring body 20, in the situation that guaranteeing maximal density radiating fin, adopt after said structure, guarantee the feasibility of manufacturing process, and its thermal diffusivity is good, can greatly extend the service life of LED lamp.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
