120 degree, cover having after globe holder certain diffuse-reflectance, the lighting angle of whole bulb lamp is the most just at 180 degree (see Fig. 1).Ball
Bubble lamp has bigger shaded area in being installed on roof backhouse, and room seems the brightest.And the flat luminous source of aluminium base is saturating
Crossing globe holder luminous, due to light source to lampshade distance, on sense organ, bulb lamp luminosity is uneven.
Being directed to above-mentioned deficiency, prior art one [CN201100601Y] proposes a kind of LED lamp, including lamp holder 3, lamp
Main body 1, lampshade 2, it is arranged on lamp main body 1 front end the lamp support 4 being placed in lampshade 2 and is arranged on the electricity in lamp main body 1
Road plate, lamp support 4 is made up of an installation portion 41 in regular dodecahedron and a junction 42, a face of installation portion 41 and company
Connect front end, portion 42 to connect, other 11 faces of installation portion 41 have a LED lamp bead 43, in order to heat radiation, each LED respectively
The power of pearl 43 is 1 watt.The installation portion 41 of lamp support 4 and the connecting portion 42 of spring-like are tightly linked, connecting portion 42 and lamp main body 1
It is tightly linked, and three is made by aluminum material or copper material, is provided with netted louvre on the sidewall of lamp main body 1
11。
But the thermal component in above-mentioned prior art one is aluminum or copper, its weight is relatively big, and radiating effect is general, and nothing
Method realizes the outgoing of fluorescent light.
Prior art two [CN203940293U] proposes a kind of omnibearing luminous LED, includes the most successively
Lamp holder and lampshade, be provided with air channel in lampshade, in air channel, upper end is provided with fan, and air channel passes aluminium base, and aluminium base is regular polygon,
Each Middle face of aluminium base outer surface is provided with LED light source, and the peripheral uniform some louvres of LED light source, air channel includes connecting into
Outer tube, inner tube and the capillary tube of one, outer tube is positioned at outside aluminium base, and inner tube and capillary tube are positioned at inside aluminium base, capillary tube
Quantity identical with the face number of aluminium base, capillary end connects FENGDOU, goes out the FENGDOU back side just to LED light source, at the bottom of lampshade
Portion is provided with air outlet.
But using fan to dispel the heat in above-mentioned prior art two, fan also needs to extra power supply, adds whole dress
Put complexity, and the outgoing of fluorescent light cannot be realized equally.
Same defect also appears in prior art three [CN204005725U], in four [CN1125939C].

Detailed description of the invention
Below in conjunction with figure and specific embodiment, technical scheme is described further.
As a example by three-dimensional dodecahedron luminescent ball bulb, its irradiating angle can reach more than 350 degree, can illuminate whole room
Room.And lamp bead to globe holder apart from of substantially equal, on sense organ, bulb lamp luminosity is highly uniform.
Described substrate or substrate use patch 12 body aluminium radiator fins of section bar in aluminium base or substrate.In the fin of light source
It is hidden in light source internal, by radiating fin, heat is exported to outside bulb lamp, reduce the volume of bulb lamp, again maximal efficiency
Derive the heat (see Fig. 2) distributed on aluminium base.
Refering to Fig. 2,3, it is shown that the internal structure exploded view of the present invention.First it is the dodecahedron aluminum heat radiation selecting hollow
Sheet, the aluminium base of the regular pentagon welding LED chip be placed with dodecahedron aluminium radiator fin dispel the heat accordingly unilateral on, positive five
There is positive and negative power supply pad at the edge of limit shape, the electrode welding on adjacent two panels regular pentagon aluminium base to together, both rises
Arrive the function that power supply connects, achieve again pentagon aluminium base fixing on dodecahedron aluminium radiator fin.Electrode cable exists
The dodecahedron fin of hollow passes, is connected on electrode pin through radiating fin.Dodecahedron aluminium radiator fin is with scattered
Hot fin is bonding integral by heat-conducting glue, and aluminium radiator fin and electrode pin are bonding integral by insulating cement, buckle acryl
Transparent lamp shade.So far the making without the emitting led bulb lamp in dead angle is completed.
Described radiating fin uses porous plastic materials, radiating fin is cut or is molded as required form, and dissipating
The surface configuration of hot fin is coated with thermal dispersant coatings, including cut cellular internal surface, to further provide for radiating surface, described
Thermal dispersant coatings includes arranging photonic crystal tube material in the polymer, and the thickness of described thermal dispersant coatings is less than 500 microns, and dissipates
Hot coefficient is 40-400W/m K, relative to the common aluminum of the prior art not including described thermal dispersant coatings, copper heat radiating fin
Sheet, the radiating effect of the radiating fin of the application is higher, and quality is the least.
Refering to Fig. 4, luminous without dead angle in order to realize fluorescence, the LED chip that described LED lamp bead includes is arranged on described solid
On polyhedral substrate, the area ratio that LED chip is coated with phosphor powder layer and pad, phosphor powder layer and pad is 2.5:1～10:
1, the thickness of phosphor powder layer is more than the thickness of pad, on the one hand, fluorescence luminescent material thickness is set and the band of position ensures
The uniformity of outgoing fluorescence and intensity, the luminous parameters such as illumination, on the other hand ensure suitable area and the pad of height and light
Source current realizes electrical connection.
The above is only the preferred embodiment for the present invention.It should be pointed out that, that the member of ordinary skill for the art comes
Saying, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and modification, these improve and modification also should
This is considered as protection scope of the present invention.
