Description

A kind of LED radiation shell

Technical field

The utility model is related to LED illumination lamp, particularly a kind of LED radiation shell.

Background technology

LED（English full name is：Light Emitting Diode, are translated into：Light emitting diode）It is a kind of solid semiconductor Device, can directly convert electrical energy into luminous energy., used as illuminating source, with lighting, the short, reference color temperature of delay is wide, luminous for LED The features such as intensity is high, luminous efficiency is high, anti-seismic performance is good；The characteristics of having long service life because of LED, has progressively substituted incandescent Lamp, electricity-saving lamp, start various occasions and widely use, but because LED package areas are small, the radiating by convection current and radiation is few, from And high heat is generated in minimum volume, and

The heat resistance of LED is very poor, and substantial amounts of heat aggregation can cause the deterioration of chip, have a strong impact on the hair of LED lamps Optical property and service life, therefore, good heat dispersion is the guarantee of LED lamp excellent properties..

The content of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple structure, the LED of good heat dissipation effect Shell.

The utility model solves the technical scheme that its technical problem used：

A kind of LED radiation shell, including ring fin group, the ring fin group upper and lower ends are respectively arranged on the first guide rail Ring, the second guide rail ring, enable ring fin group to rotate, and the ring fin group is made up of the fin of at least more than three, institute Stating ring fin group includes inner ring fins set, outer shroud fins set, forms double-deck radiator structure, increases heat-sinking capability, the fin Including the right-oblique inner ring fin in relative axis, the left-oblique outer shroud fin in relative axis, increase air on radiation shell Flowing, improves radiating effect；The first guide rail ring and the second guide rail ring are provided with interior guide rail ring corresponding with inner ring fins set, The first guide rail ring and the second guide rail ring are provided with outer guide ring corresponding with outer shroud fins set.

Used as a preference, the fin is provided with the radiating fin ray that section is triangle, increases area of dissipation.

Used as a preference, the fin upper and lower ends are provided with flanging, and the hemmed edges center is provided with trapezoidal Hooked scarf, the flanging is provided with positioned at the hook position of trapezoidal hooked scarf offside, and single fin is connected with each other.

Used as a preference, the spacing between the inner ring fin is 1/2nd of the spacing between outer shroud fin, Increase the number of fins in unit area.

Used as a preference, the inner ring fin, outer shroud fin angle of inclination are 30 °.

Used as a preference, the inner fin group rotation direction is clockwise direction, the outer fins set rotation direction Counterclockwise, to increase the relativity of air flow.

The beneficial effects of the utility model are：This radiation shell forms bilayer by setting inner ring fins set, outer shroud fins set Radiator structure, while the difference and the difference of rotation direction that pass through inside and outside fin setting direction, air on enhancing radiation shell Mobility, while increasing the number of fin in unit area by the difference of spacing of fin in inner ring fins set, outer shroud fins set Amount, further improves heat-sinking capability.
