Preferably, described LED lamp fin comprises four described the first radiating fins and a plurality of the second radiating fin, four described the first radiating fins are arranged on the sidewall of body equably, and a plurality of described the second radiating fins are arranged between four described the first radiating fins equably.
Preferably, described the first radiating fin also has first base portion of structure in the form of sheets, one end of described the first base portion is connected on the sidewall of described body, the other end of described the first base portion is provided with at least two described the first furcations, and be provided with the first installing hole on described the first base portion, the junction of described the first furcation and described the first base portion is provided with the second installing hole.
Preferably, described the second radiating fin also has second base portion of structure in the form of sheets, and an end of described the second base portion is connected on the sidewall of described body, and the other end of described the second base portion is provided with at least two described the second furcations.
Preferably, the described body structure that is square offers manhole on the described body, and is provided with some the 3rd installing holes on the inwall of described body, and described the 3rd installing hole is along the length direction setting of described body.
Compared with prior art, because LED lamp fin of the present utility model, it comprises a body, be along the sidewall of described body and be provided with radially the first radiating fin and the second radiating fin, and the end of described the first radiating fin is provided with at least two the first furcations of structure in the form of sheets, and the end of described the second radiating fin is provided with at least two the second furcations of structure in the form of sheets; Have the first radiating fin of the first furcation and have the second radiating fin of the second furcation, increased area of dissipation, significantly improve the radiating effect of fin, and it is simple in structure, easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model LED lamp fin.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, similar element numbers represents similar element in the accompanying drawing.The utility model provides a kind of fin 1, is applicable to LED shot-light or LED stage lighting, good heat dissipation effect, and easy for installation.
As shown in Figure 1 and Figure 2, LED lamp fin 1 provided by the utility model, it comprise one be square structure body 10, be arranged at the first radiating fin 20 and the second radiating fin 30 on the lateral wall of described body 10.Offer manhole 11 on the described body 10, and have some the 3rd installing holes 12 that cave inward and form on the inwall of described body 10, described the 3rd installing hole 12 is along the length direction setting of described body 10; In an embodiment of the present utility model, be provided with four angles settings that 12, four the 3rd installing holes 12 of four the 3rd installing holes correspond respectively to body 10; Like this, make things convenient on the one hand being connected of body 10 and miscellaneous part, another heat that light source is produced reaches the first radiating fin 20 and the second radiating fin 30 rapidly by body 10, the raising radiating efficiency.
On the lateral wall of described body 10, the first radiating fin 20, the second radiating fin 30 are radially and arrange, and the end of the first radiating fin 20, the second radiating fin 30 is positioned on the same circumference.Preferably, described LED lamp fin 1 comprises that 20, four described the first radiating fins 20 of four the first radiating fins are arranged on the sidewall of body 10 equably, and a plurality of described the second radiating fins 30 are arranged between four described the first radiating fins 20 equably.In the present embodiment, four the first radiating fins 20 are arranged at respectively the middle part of four sidewalls of body 10; Certainly, the quantity of the first radiating fin 20 is not as limit, and it can arrange arbitrarily as required, and the link position of the first radiating fin 20 is not limited with the present embodiment yet, also can be arranged at the optional position on the outer wall of body 10.
