The specific embodiment
For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below the technical scheme that the utility model embodiment provides is elaborated with reference to accompanying drawing.
The utility model comprises the LED luminescence unit 3 that a plurality of LED constitutes, and also is included as LED luminescence unit 3 electric energy transmittings and the metal base 4 that its heat is shifted, metal trunk 1 and metal limb 2; Described LED luminescence unit 3 is welded on the metal limb 2, and described metal limb 2 is welded on the outer wall of metal trunk 1; Described metal trunk 1 is welded on the metal base 4; Described LED luminescence unit 3, metal limb 2, metal trunk 1 and metal base 4 four form tree.The structure of the root system of described metal base 4, metal trunk 1, metal limb 2, LED luminescence unit 3 similar plants, trunk, limb, leaf.
In Fig. 1,2,3, metal limb 2 and the LED luminescence unit 3 that is welded on the metal limb 1 are arranged on the metal trunk 1 by the Fibonacci spiral way.
On each plane vertical with the metal trunk, along the protruding metal limb 2 of metal trunk 1 circumference, be welded on LED luminescence unit 3 on the metal limb 2 and be adjacent between the LED luminescence unit 3 on plane and be 137.5 ° or 222.5 °, described metal limb 2 is to axioversion.
As, 3 metal limbs 2 and the LED luminescence unit 3 that is welded on the metal limb 2 are being set on the metal trunk 1, along the metal limb 2 on first plane and be welded on LED luminescence unit 3 on the metal limb 2 around being a circle to the metal limb 2 on the 3rd plane and the LED luminescence unit 3 that is welded on the metal limb 2, can draw around metal trunk 1 one circles, required metal limb 2 and LED luminescence unit 2 numbers are 3.
For another example, 5 metal limbs 2 and the LED luminescence unit 3 that is welded on the metal limb 2 are being set on the metal trunk 1, along the metal limb 2 on first plane and be welded on LED luminescence unit 3 on the metal limb 2 around being two circles to the metal limb 2 on the 5th plane and the LED luminescence unit 3 that is welded on the metal limb 2, can draw around metal trunk 1 two circles, required metal limb 2 and LED luminescence unit 2 numbers are 5.
Again for example, 8 metal limbs 2 and the LED luminescence unit 3 that is welded on the metal limb 2 are being set on the metal trunk 1, along the metal limb 2 on first plane and be welded on LED luminescence unit 3 on the metal limb 2 around being three circles to the metal limb 2 on the 8th plane and the LED luminescence unit 3 that is welded on the metal limb 2, can draw around metal trunk 1 three circles, required metal limb 2 and LED luminescence unit 3 numbers are 8.
... and the like.
Can draw thus, described metal limb 2 and the LED luminescence unit 3 that is welded on the metal limb 2 are arranged by Fibonacci spiral progression.
As shown in Figure 4, on each plane vertical with metal trunk 1, an only protruding metal limb 2, the angle that is welded on the every adjacent two LED luminescence units 3 on the metal limb 2 is 180 °.Be the LED luminescence unit that only welds on each plane on a metal limb and the metal limb, give birth to alternately.
On each plane vertical with metal trunk 1, be provided with a plurality of metal limbs 2 that angle equates, LED luminescence unit 3 on adjacent two metal limbs 2 and the metal limb 2 staggers, 3 repetitions of LED luminescence unit on inferior adjacent two metal limbs 2 and the metal limb.
On each plane vertical,, be welded on the LED luminescence unit 3 that LED luminescence unit 3 on the metal limb 2 is adjacent the plane and be crisscross arranged along the protruding a plurality of metal limbs 2 of metal trunk 1 circumference with metal trunk 1.
As shown in Figure 5, on each plane vertical with metal trunk 1, protruding two metal limbs 2, per two metal limbs 2 and welding two LED luminescence units 3 thereon are oppositely arranged.Protruding 2 the metal limbs 2 of the circumference of first upper edge, plane metal trunk 1 of vertical metal trunk be welded on LED luminescence unit 3 on the metal limb 2, also protruding 2 the metal limbs 2 of the circumference of upper edge, second plane metal trunk 1 and be welded on LED luminescence unit 3 on the metal limb 2, also protruding 2 the metal limbs 2 of the circumference of the 3rd upper edge, plane metal trunk 1 and be welded on LED luminescence unit 3...... on the metal limb 2, metal limb 2 on described second plane be welded on metal limb 2 on LED luminescence unit 3 relative first planes on metal limb 2 and the LED luminescence unit 3 that is welded on the metal limb 2 shift to install, metal limb 2 on described the 3rd plane be welded on metal limb 2 on LED luminescence unit 3 relative second planes on metal limb 2 and the LED luminescence unit 3 that is welded on the metal limb 2 shift to install ... as optimal way, on adjacent two planes vertical with metal trunk 1, metal limb 2 that is oppositely arranged and welding LED luminescence unit 3 thereon are right-angled intersection.
Expansion as present embodiment, other embodiment that are easy to expect with those skilled in the art in other words, promptly by that analogy, on each plane vertical with metal trunk 1, along can protruding a plurality of metal limbs 2 on metal trunk 1 circumference, as 3,4,5 ... the metal limb 2 on each plane equates with the number of the LED luminescence unit 3 that is welded on metal limb last 2, different is, the metal limb 2 on plane is compared the metal limb 2 on its previous or back plane and is welded on metal limb last 2 with the LED luminescence unit 3 that is welded on metal limb last 2 LED luminescence unit 3 is dislocation arrangements.
And for example, at protruding 8 metal limbs 2 of the circumference of upper edge, first plane metal trunk 1 and the LED luminescence unit 3 that is welded on the metal limb 2, protruding 7 the metal limbs 2 of the circumference of upper edge, second plane metal trunk 1 and be welded on LED luminescence unit 3 on the metal limb, also protruding 2 the metal limbs 2 of the circumference of upper edge, three planes metal trunk 1 and be welded on LED luminescence unit 3...... on the metal limb 2, metal limb 2 on described second plane be welded on metal limb 2 on LED luminescence unit 3 relative first planes on metal limb 2 and the LED luminescence unit 3 that is welded on the metal limb 2 shift to install, the metal limb 2 on described the 3rd plane be welded on metal limb 2 on LED luminescence unit 3 relative second planes on metal limb 2 shift to install with the LED luminescence unit 3 that is welded on the metal limb 2 ... and the like.That is, successively decrease one by one with respect to the metal limb 2 on last plane and the LED luminescence unit 3 that is welded on the metal limb 2 in one plane, back.
This structure Design makes that the LED luminescence unit arranges that density is proper, fullest ground irradiation and dispelling the heat.
