The technical solution of the utility model is: a kind of radiator, including fitting in the heat-radiating substrate on heater members with a side surface and being arranged at the radiating fin on opposite side surface of described heat-radiating substrate.Described radiating fin is divided at least two groups, and each radiating fin of each radiating fin group all arranges in homogeneous radiation shape and is distributed ringwise, and the radiating fin group that each is distributed ringwise is arranged in heat-radiating substrate surface with concentric ring type again；In the radiating fin group that any two is adjacent, the spacing of the inner circle one end of the radiating fin that the spacing of the outer circle one end of the radiating fin that any two panels of being positioned in the radiating fin group of inner ring is adjacent is adjacent more than any two panels in the radiating fin group being positioned at outer ring.

Further, described each radiating fin is all by riveting or being welded and fixed on heat-radiating substrate, or each radiating fin adheres on heat-radiating substrate by means of heat-conducting glue.

Further, each radiating fin group is concentric-ring pattern arrangement.

Further, arrange at a distance of predetermined spacing between two groups of adjacent radiating fin groups.

Further, described predetermined spacing is 0-20mm.

Further, described radiating fin is all arranged radially with identical central point.

Further, described radiating fin includes radiating part and the most vertically bends the connecting portion extending formation from the bottom edge of radiating part, and described connecting portion fits with the surface of heat-radiating substrate.

On the other hand, this utility model also provides for a kind of LED lamp, including LED lamp panel, radiator and the cover cap lampshade outside the light exit facet of LED lamp panel, described radiator is as above radiator described in any one, and the one side of the heat-radiating substrate of described radiator fits with LED lamp panel.

After using technique scheme, this utility model at least has the advantages that by radiating fin is divided into the radiating fin group that at least two groups arrange with concentric ring type successively ring set, and, in the radiating fin group that any two is adjacent, the spacing of the inner circle one end of the radiating fin that the spacing of the outer circle one end of the radiating fin that any two panels of being positioned in the radiating fin group of inner ring is adjacent is adjacent more than any two panels in the radiating fin group being positioned at outer ring, such that it is able to the most reasonably arrange the distribution of the radiating fin of outer ring, make to locate that still there is enough cooling surface areas in the outer part, such that it is able to promote the heat dispersion of entirety well, by contrast, more excellent heat dispersion can be reached with suitable external diameter.And have employed the LED lamp of this radiator, owing to radiator performance is excellent, large-scale or ultra-large type round radiator heat-dissipation area and the inadequate problem of density can be solved well, supporting the solution of large LED light fixture heat radiation simultaneously, be more beneficial for realizing the exquisite shape-designing that LED lamp is overall.

Detailed description of the invention

In order to further illustrate principle of the present utility model and structure, in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

Referring to Fig. 1 to Fig. 4, this utility model provides a kind of radiator 1, including the heat-radiating substrate 10 fitted in a side surface on heater members and the radiating fin 12 on the opposite side surface being arranged at described heat-radiating substrate 10.

Described radiating fin 12 is divided at least two groups, below in conjunction with in the description that the embodiment shown in Fig. 1 ~ Fig. 3 is carried out, illustrate as a example by totally two groups being provided with first radiating fin group the 20, second radiating fin group 30, it is understandable that, demand according to heat dispersion, more groups of radiating fins can be set, such as: three groups, four groups, the most groups.

Each radiating fin 2 of first radiating fin group the 20, second radiating fin group 30 all arranges in homogeneous radiation shape and is distributed ringwise, first radiating fin group the 20, the second radiating fin group 30 being distributed ringwise is arranged in heat-radiating substrate 10 surface, preferably concentric-ring pattern arrangement with concentric ring type again.It is further preferred that described radiating fin 12 is all arranged radially with identical central point.

In radiator as shown in Fig. 1 ~ Fig. 3, with the first radiating fin group 20 as inner ring, and the second radiating fin group 30 is looped around the periphery of the first radiating fin group 20 for outer ring；The spacing of the inner circle one end of the radiating fin 12 that the spacing of the outer circle one end of the radiating fin 12 that any two panels of being positioned in the first radiating fin group 20 of inner ring is adjacent is adjacent more than any two panels in the second radiating fin group 30 being positioned at outer ring, in the specific implementation, it might even be possible to the spacing of inner circle one end of radiating fin 12 adjacent for any two panels in each radiating fin group is disposed as identical.

For consideration easy to process, described each radiating fin 12 all can be fixed on heat-radiating substrate 10, additionally, each radiating fin 12 also can also adhere on heat-radiating substrate 10 by means of heat-conducting glue in modes such as riveting or welding.In the specific implementation, as shown in Figure 4, described radiating fin 12 includes radiating part 120 and the most vertically bends the connecting portion 122 extending formation from the bottom edge of radiating part 120, described connecting portion 122 fits with the surface of heat-radiating substrate 10, and then again by modes such as rivet welding or heat-conducting glue stickups by it with heat-radiating substrate 10 compact siro spinning technology, in order to heat can extremely efficiently conduct to radiating fin 12 from heat-radiating substrate 10.

When reality processing and assembling, between adjacent the first radiating fin group 20 and the second radiating fin group 30, a predetermined spacing can be set, it is preferable that predetermined spacing is 0-20mm, it is so designed that and can preferably ensure air-flow flowing between two groups of radiating fin groups, heat radiation performance.

On the other hand, this utility model also provides for a kind of LED lamp 4 applying above-mentioned radiating fin, as shown in Figure 5, described LED lamp includes lamp socket 40, the radiator as above 1 being installed on lamp socket 40, LED lamp panel 42 and cover cap lampshade 44 outside the light exit facet of LED lamp panel 42, and the one side of the heat-radiating substrate 1 of described radiator 1 fits with LED lamp panel 42.Thus, when LED lamp 4 works, the heat that each LED chip 420 in LED lamp panel 42 produces can be transferred on heat-radiating substrate 10 rapidly, and then is passed to radiating fin 12 by heat-radiating substrate 10 again, and the surface from radiating fin 12 distributes the most again.

Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is limited by claims and equivalency range thereof.
