Abstract

The utility model discloses a heat dissipation device applied to an LED lamp. The heat dissipation device comprises a heat dissipation device body with the circular-cup-shaped appearance and a cavity inside. The bottom of the cavity of the heat dissipation device body is provided with a plane for fixedly installing an LED light-emitting body. A solid thermal conduction column is arranged in the middle of the outer wall of the bottom of the heat dissipation device body. A plurality of heat dissipation fins which are connected with the outer circumference of the heat dissipation device body are evenly arranged on the outer circumference of the thermal conduction column. The cross section of each heat dissipation fin is in an arc shape. The solid thermal conduction column is arranged in the middle of the outer wall of the bottom of the heat dissipation device body, can rapidly transmit heat generated in the working process of the LED light-emitting body to the heat dissipation fins and then efficiently exchanges heat with air through the heat dissipation fins, and therefore the heat dissipation effect of the LED lamp with the heat dissipation device is good.

Description

A kind of radiator that is applied to LED lamp

Technical field

The utility model relates to LED lamp, particularly a kind of radiator that is applied to LED lamp.

Background technology

Along with social development and scientific and technical progress; people more and more focus on saving the energy and protection of the environment; due to LED light fixture, there are the advantages such as energy consumption is low, long service life and are more and more subject to people's favor; but LED lamp in the course of the work; heating is large; easily cause it to damage, so the heat dissipation problem of LED lamp become the significant problem of its development of restriction.

Utility model content

In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, again can be so that the radiator of the good heat dissipation effect of LED lamp.

The utility model for the technical scheme that solves its technical problem and adopt is:

A kind of radiator that is applied to LED lamp, comprise that the rounded cup-shaped of profile and its inside are with the radiator body of cavity volume, the cavity volume bottom of this radiator body is provided with one for fixedly mounting the plane of shelving of LED illuminator, the place, bottom outer wall centre position of described radiator body is provided with a solid heating column, on the periphery wall of this heating column, be evenly provided with the some radiating fins that are connected with radiator body periphery wall, the cross section of described radiating fin is circular arc.

As the improvement of technique scheme, the gradient at described radiating fin outer peripheral edges place is 1-10 degree.

As the further improvement of technique scheme, the periphery wall of described radiator body between adjacent two radiating fins is arc surface.

Further, the bottom of described radiator body is provided with a through hole of making way for electric lead.

Further again, on the bottom periphery wall of described radiator body, be provided with one and the integrated projection of described heating column, described through hole is opened on this projection.

The beneficial effects of the utility model are: because the utility model arranges a solid heating column by the place, bottom outer wall centre position at radiator body, the heat producing when LED illuminator can be worked by this heating column is promptly delivered to radiating fin place, and then carry out efficient exchange heat by radiating fin and air, thereby made to adopt the good heat dissipation effect of the LED lamp of above-mentioned radiator, cross section due to radiating fin is circular arc simultaneously, in the situation that do not change the diameter dimension of radiator, increased the contact area of radiating fin and air, strengthened widely the heat-sinking capability of radiator, the periphery wall of radiator body between adjacent two radiating fins is arc surface in addition, therefore after the air between adjacent two radiating fins is heated, can be more easily toward rising along this arc surface, accelerate the Air Flow between adjacent two radiating fins, further promoted the heat-sinking capability of radiator.

Accompanying drawing explanation

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

Fig. 1 is surface structure schematic diagram of the present utility model;

Fig. 2 is the surface structure schematic diagram of another angle of the utility model;

Fig. 3 is the top view of bottom outer wall of the present utility model.

The specific embodiment

Referring to figs. 1 through Fig. 3, a kind of radiator that is applied to LED lamp, comprise that the rounded cup-shaped of profile and its inside are with the radiator body 1 of cavity volume 10, in the utility model, the preferential environment-friendly highly efficient heat conduction aluminum alloy that adopts of described radiator body 1 is manufactured, further, the bottom wall thickness of radiator body 1 is 8-16 centimetre, cavity volume 10 bottoms of this radiator body 1 are provided with one and shelve plane 100 for what fixedly mount LED illuminator, the place, bottom outer wall centre position of described radiator body 1 is provided with a solid heating column 11, on the periphery wall of this heating column 11, be evenly provided with the some radiating fins 12 that are connected with radiator body 1 periphery wall, the cross section of described radiating fin 12 is circular arc, because the utility model arranges a solid heating column 11 by the place, bottom outer wall centre position at radiator body 1, the heat producing when LED illuminator can be worked by this heating column 11 is promptly delivered to radiating fin 12 places, and then carry out efficient exchange heat by radiating fin 12 and air, thereby made to adopt the good heat dissipation effect of the LED lamp of above-mentioned radiator, cross section due to radiating fin 12 is circular arc simultaneously, in the situation that do not change the diameter dimension of radiator, increased the contact area of radiating fin 12 with air, strengthened widely the heat-sinking capability of radiator.

Further, the manufacturing for the ease of radiator, the gradient at described radiating fin 12 outer peripheral edges places is 1-10 degree, therefore when adopting the mode of casting to manufacture radiator, because the gradient at the outer peripheral edges place of radiating fin 12 is 1-10 degree, therefore facilitate molding, thereby made the manufacturing of radiator more simple and convenient quick.

Further again, heat-sinking capability for heat radiation device, the periphery wall of described radiator body 1 between adjacent two radiating fins 12 is arc surface, therefore after the air between adjacent two radiating fins 12 is heated, can be more easily toward rising along this arc surface, accelerate the Air Flow between adjacent two radiating fins 12, promoted the heat-sinking capability of radiator.

Further, in order to make to adopt the wiring of LED lamp of radiator of the present utility model convenient, the bottom of described radiator body 1 is provided with a through hole 13 of making way for electric lead, therefore the electric lead being connected with LED illuminator can pass from the through hole 13 of radiator body 1, avoids electric lead pass and affect attractive in appearance from the front portion of LED lamp.

Further again, on the bottom periphery wall of described radiator body 1, be provided with one and the integrated projection 14 of described heating column 11, described through hole 13 is opened on this projection 14, both can avoid through hole 13 to expose, can further increase the volume of heating column 11 again, further strengthen the heat-sinking capability of radiator simultaneously.

The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
