The present invention has invented " 360 degree (body is luminous) high light efficiency luminescence generated by light diode " according to above-mentioned basic principle, and its basic structure constitutes as Fig. 2.
The present invention is by with the LED support of reflector, the semiconductor light emitting chip, and lead, transparent epoxy glue, photoluminescent phosphor, and transparent bonded adhesives constitutes.In this basic structure, if when hardness, mechanical strength, resistance to wear and the chemical stability of transparent bonded adhesives is not enough, can be at the formed outer surface envelope of transparent bonded adhesives transparent protection material.(referring to Fig. 6)
(4) 360 degree (body is luminous) high light efficiency luminescence generated by light diode implementation procedure (see figure 2)s:
Proper semiconductor's luminescence chip on LED support, and both finish the circuit connection through lead.Use transparent epoxy glue embedding moulding then, thereby constitute " light-emitting diode ".With transparent bonded adhesives and photoluminescent phosphor, after the mixing and stirring and the degassing, be mixed with " fluorescent material glue " by a certain percentage.Again with in " light-emitting diode " immersion " fluorescent material glue ", and make the surface of the transparent epoxy glue of " light-emitting diode " apply (adhering to) fully to go up " fluorescent material glue ".After the curing, just formed one deck " thin-film body " that one deck is made of " transparent bonded adhesives and photoluminescent phosphor " on the surface of transparent epoxy glue.Be somebody's turn to do " thin-film body " for protection, be solidified into protective layer (also can be the protective of tool body) with transparent protection material thereon.This protective layer (protective) has high printing opacity, high rigidity mechanical strength, high-wearing feature and good chemical stability.(referring to Fig. 6)

Embodiment
With reference to Fig. 2, present embodiment is made up of transparent epoxy glue 1, semiconductor light emitting chip 3, photoluminescent phosphor 5, lead 6, transparent protection material 7, transparent bonded adhesives 8, LED support 12.
The light-emitting diode of being made up of transparent epoxy glue 1, semiconductor light emitting chip 3, lead 6, LED support 12 9 wherein, this composition technology belongs to traditional manufacturing process.In realizing 360 degree (body is luminous) high light efficiency luminescence generated by light diodes, crucial implementation method is exactly that " transparent bonded adhesives 8 and photoluminescent phosphor 5 " is in transparent epoxy glue 1 surface-coated and be solidified into " thin-film body 11 ".
Because in the light-emitting diode manufacturing, when 1 moulding of transparent epoxy glue, extensively adopt " release agent " demoulding, transparent epoxy glue 1 smooth surface behind the curing molding in addition, thereby increased the formation difficulty of " thin-film body 11 ", we have taked following measure at this problem:
Method one, to transparent epoxy glue 1 surface " frosted glass processing ":
Light-emitting diode 9 after " frosted glass processing " and the light flux values contrast back before the processing are found, the luminous flux decline 1.58% of the light-emitting diode 9 after the processing, but the light-emitting diode 9 employing primary coatings (as Fig. 3) after " frosted glass processing ".Make coat be coated on the outer surface of transparent epoxy glue 1 fully, after the curing, resulting " thin-film body 11 " film-formation result is good.(transparent bonded adhesives 8 is selected the organic siliconresin bonded adhesives for use in the present embodiment)
Method two, twice coating done on transparent epoxy glue 1 surface:
Light-emitting diode 9 need not " frosted glass processing ", and take the method for twice coating (Fig. 3, Fig. 4, Fig. 5) to be: for the first time light-emitting diode 9 is immersed in " the fluorescent material glue " 10 of low concentration fully, make it to form (Fig. 4) effect after the curing, because photoluminescent phosphor 5 is in " fluorescent material glue " 10, remain with lenticular and exist, thereby it is also coarse relatively to solidify the surface of " thin-film body " 11 that the back forms; Light-emitting diode 9 with the tool matsurface immerses (see figure 5) in higher " the fluorescent material glue " 10 of concentration once more for the second time, solidify then, " thin-film body " 11 resulting after twice coating has higher luminous flux, but " thin-film body " 11 that forms is even not as method 1.(in the present embodiment, transparent bonded adhesives 8 is selected the organic siliconresin bonding agent for use)
3, method three: transparent bonded adhesives 8 is selected photosensitive optical cement for use.
Photosensitive optical cement has the intensity height of epoxy resin, shrinkage is little, the characteristics that chemical stability is good, the viscosity that has unsaturated polyester resin again is little, the processing performance that wettability is good, the characteristics of quick solidifying under rayed adopt " thin-film body " 11 that applies back formation once or twice more easy to control, and need not " frosted glass processing " taked on the surface of transparent epoxy glue.Take painting method equally, resulting " thin-film body " 11 is even, and film forming is also more satisfactory, but cost is higher.
From the method for above-mentioned three kinds of formation " thin-film body 11 " as can be known, the material of realizing the process of " thin-film body 11 " and selection has varied, each tool chief.
Moulding about transparent protection material 7:
Transparent protection material 7 material therefors, the scope of its selection is very big, can use transparent epoxy glue, also can be with organic siliconresin bonded adhesives or the like, and also its molding mode also has variedly, can form diaphragm, also can form protective (referring to Fig. 6).If 360 degree (body is luminous) high light efficiency luminescence generated by light diodes selected transparent bonded adhesivess 8, its hardness, mechanical strength, resistance to wear, when chemical stability is enough, transparent protection material 7 can not wanted yet.
