The upright projection of straight line where the section fin three center of circle.
Further, the intrados of the left section of fin and right section of fin is extended with short fin, the vertical throwing of short fin
The upright projection of shadow sheet fin in the fin of stage casing, the air velocity of intrados one side is small, but pressure is big, and air is led
To at short fin, not when sheet fin is parallel, short fin also ensures that pedestal has enough heat dissipations for short fin heat dissipation or air
Efficiency.
Further, the pedestal, round platform and radiating fin are integrally formed, and installation number of parts is reduced, and structure is more steady
It is fixed, without assembling procedure, reduce production cost.
Further, two panels the second arc fin and card line seat, card line seat and second are additionally provided in the annular protrusion
Arc fin bottom is fixed on round platform, and both ends offset with annular protrusion, and two panels the second arc fin is symmetrical arranged composition
Screens, round platform are provided with wire guide in card line seat one side, and wire guide connects the cavity inside round platform, and the conducting wire of downlight is by wire guide
Place is drawn, and is connected convenient for conducting wire with home circuit, and screens, which is set, causes pedestal to have " handle ", takes, puts more smoothly.
The beneficial effects of the utility model are as follows：
（1）The understructure of such downlight, radiating fin, round platform and pedestal are integrally formed, and are made from a material that be thermally conductive,
The exterior surface area of pedestal can be increased the heat derives in LED downlight, round platform and radiating fin, improve LED downlight
Heat dissipation effect, air from the gap by, since left section of fin and right section of fin are arc fin, the sky of arc fin both sides
Gas velocity is inconsistent, and in the fast one side of air velocity, radiating fin can preferably distribute the heat of pedestal.
（2）Secondly, the air velocity of left section of fin and right section of fin close to stage casing fin one side is more than the sky of its opposite side
Gas velocity, better heat-radiation effect.
（3）Further more, producer's printed goods information is convenient in space in annular protrusion, cutout unit makes air avoid by annular protrusion
Stop, air continues to flow by cutout unit, and takes away the heat on the fin of stage casing.
（4）It in addition, the conducting wire of downlight is drawn by wire guide, is connected convenient for conducting wire with home circuit, screens is set so that bottom
Seat has " handle ", takes, puts more smoothly.
