The sloping portion of radiating fin of the center line both sides and the angle of base plate of radiator be respectively 30 degree~90 degree, 90 degree~150 degree.

The one side of the radiating fin be plane, another side be curved surface；Or radiating fin is by vertical component and rake Divide and constitute, vertical component is vertical with base plate of radiator, sloping portion carries an angle with base plate of radiator.

The radiating fin is screwed on base plate of radiator, or radiating fin and base plate are with entirety.

With the protrusion of multiple semicircles on the radiating fin.

Being cut with the base plate of radiator increases the ventilation space of radiating effect.

The radiating fin is connected as a single entity, and is cut according to ventilation space.

The radiator outside sets outer cover.

The centre bore rear portion of the radiator is lamp stand connecting hole, front end for Switching Power Supply is set.

The radiator is made up of aluminium or almag.

Superiority of the present utility model：1st, the radiating fin of this LED is entering into wing using connected mode, air is inclined Panel region, is flowed in form of slowing down, one plane of radiating fin, a curved surface, and the wing shapes with aircraft are similar, or carry Certain angle, is divided into vertical area and tilting zone, and air enters into fin region, is flowed on the fin with radian or certain angle Dynamic, fin both sides one side flow velocity is fast, one side flow velocity is slow, is superimposed between the two, increases the ability that wind takes away heat, by heat band Walk, drastically increase radiating effect.2nd, LED heat prestissimo is transmitted on radiating fin, radiating fin by with sky The deceleration heat exchange of gas, increases area and airborne period of the air on fin, and heat is distributed, and forms turbulent flow.3rd, open Powered-down source is placed in radiator lamp stand hole, improves the Switching Power Supply life-span, and loose structure is divulged information, and radiator can be reduced simultaneously Flowing velocity, forms turbulent flow in lamp housing.4th, the utility model can reduce LED lamp bead temperature, improve the use of LED luminous tube In the life-span, reduce use cost.This radiator may act as LED street lamp and use, it is also possible to used as LED projector lamp, searchlight Use, reduce die cost.5th, the substrate portion of radiator is cut away, the space for reserving increases radiating effect.
