Abstract

The utility model discloses an LED lamp radiating structure comprising a fastening ring, a radiating fin set, and a radiating base. The upper end of the radiating fin set is connected with the fastening ring in a clamped manner. The lower end of the radiating fin set is connected with the radiating base in a clamped manner. The radiating fin set is composed of a plurality of radiating fins in a circle. Each radiating fin has wide top and narrow bottom. The upper end and upper portion of each radiating fin are provided with turnups in the same direction respectively. Each radiating fin is provided with a plurality of guide holes admitting air flow and a plurality of raised lines which increase radiating area. The radiating fins are provided with the turnups and raised lines which increase the radiating area and the guide holes which guarantee greater air flow, and accordingly, the LED lamp radiating structure is better in radiating performance.

Description

LED lamp cooling structure

Technical field

The utility model relates to a kind of fitting structure, particularly relates to a kind of LED lamp cooling structure.

Background technology

LED illumination has been subject to paying close attention to widely as a new generation's illumination.The lighting that only relies on LED encapsulation not produce.Although the energy loss of incandescent lamp and fluorescent lamp is large, most of energy is all directly to radiate away by infrared ray, and the heating of light source is few; And LED, except the energy consuming as visible light, other energy has all converted heat to.In addition, because LED package area is little, few by the heat radiation of convection current and radiation, thus accumulated a large amount of heat.The importance of the Cooling Solution of LED illumination is more and more higher.As shown in Figure 1, traditional LED radiating lamp, is mainly comprised of lampshade 1 ', LED light source substrate 2 ', retainer ring 3 ', radiating fin group 4 ', fin retainer ring 5 ', power supply 6 ', lamp socket 7 ', lamp holder 8 '.Described radiating fin group 4 ' consists of several radiating fins, and a dry radiating fin, by being set in the outside groove 51 ' of fin retainer ring 5 ', compresses groove by machining apparatus, thereby fin is fixed.In this radiating fin group of commonly using 4 ', the area of dissipation of radiating fin is less, and air is not easy circulation.

Utility model content

The purpose of this utility model is to provide a kind of heat dispersion better LED lamp cooling structure.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of LED lamp cooling structure, and it comprises retainer ring, radiating fin group, radiating seat; The upper end of described radiating fin group and retainer ring clamping, the lower end of radiating fin group and radiating seat clamping, the radiating fin that radiating fin group surrounds ring-type by several forms; Described radiating fin is wide at the top and narrow at the bottom, in the top and upper inner form respectively one towards consistent flange, on radiating fin, offer a plurality of pod apertures and many burrs for increasing heat radiation area that allow air flow through.

The top and bottom of described radiating fin extend outward respectively one section of boss, after several radiating fins surround ring-type, its upper and lower end forms respectively a circular bulge loop, and the circular bulge loop difference holding of the upper and lower end of radiating fin group is in retainer ring and radiating seat.

A plurality of pod apertures that allow air flow through are offered in described retainer ring upper surface.

Adopt after such scheme, because the utility model has increased the pod apertures of the flange of increasing heat radiation area and burr, increase circulation of air at radiating fin, thereby make heat dispersion of the present utility model better.

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

Accompanying drawing explanation

Fig. 1 is the three-dimensional exploded view of commonly using LED radiating lamp;

Fig. 2 is axonometric drawing of the present utility model;

Fig. 3 is three-dimensional exploded view of the present utility model;

Fig. 4 is the axonometric drawing of the utility model radiating fin;

Fig. 5 is the front view of the utility model radiating fin.

The specific embodiment

As shown in Figure 2, the utility model is a kind of LED lamp cooling structure, and it comprises retainer ring 1, radiating fin group 2, radiating seat 3.

The upper end of described radiating fin group 2 and retainer ring 1 clamping, the lower end of radiating fin group 2 and radiating seat 3 clampings.

As shown in Figure 3, the radiating fin 21 that described radiating fin group 2 surrounds ring-type by several forms.The top and bottom of described radiating fin 21 extend outward respectively one section of boss 211,212(as shown in Figure 5), after several radiating fins 21 surround ring-type, its upper and lower end forms respectively a

circular bulge loop

22,23, and circular bulge loop 22, the 23 difference holdings of the upper and lower end of radiating fin group 2 are in retainer ring 1 and radiating seat 3.

As shown in Figure 4, Figure 5, described radiating fin 21 is wide at the top and narrow at the bottom, in the top and upper inner form respectively one towards consistent flange 213,214, on radiating fin 21, offer four pod apertures 215 and two burrs 216 for increasing heat radiation area that allow air flow through.

As shown in Figure 3, a plurality of pod apertures 11 that allow air flow through are offered in described retainer ring 1 upper surface.Described radiating seat 3 outer walls are provided with around all-round convex tendon 31, to increase the area of dissipation of radiating seat 3.

Emphasis of the present utility model is just: on radiating fin, increase flange, burr, pod apertures.

The above, it is only the utility model preferred embodiment, the quantity of burr and pod apertures can be determined according to needs, therefore can not limit the scope that the utility model is implemented with this, the equivalence done according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
