Description
Technical field
The invention belongs to LED technical field, particularly relate to a kind of can the LED of secondary excitation bright dipping and packaging technology thereof.
Background technology
Along with the continuous breakthrough of LED technology bottleneck, the LED product light efficiency that can stably produce for 2013 reaches 200LM/W, along with the maturity all the more of time and technology, the advantages such as LED product energy-saving environment protection health and traditional tungsten lamp, fluorescent lamp contrast its effect and more see obviously, the trend substituting traditional lighting points the day and await for it, LED illumination product after power-off and traditional lighting can compare, there is no substantial difference, lack adjection and artistic value; Meanwhile along with LED market development demand and differentiation, following LED illumination design not only will possess illumination functions and even also will realize personalized design to embody high-grade level of illumination, simultaneously more want to embody energy-conservation, environmental protection and artistic effect for outdoor scene illumination, even wish to realize more advertisement benefit and economic benefit by LED illumination.
Summary of the invention
The object of the invention is to solve a prior art difficult problem, provide a kind of can the LED of secondary excitation bright dipping and packaging technology thereof, it makes simple, energy-conserving and environment-protective, and has individual character and taste concurrently, has splendid promotion prospect.
The present invention is achieved in that
Can the LED of secondary excitation bright dipping, adopt blue chip to excite the fluorescent glue of silica gel and yellow fluorescent powder mixing and stirring, realize exciting bright dipping under "on" position; The luminous energy that the light-emitting admixture exciting silica gel, glass microballoon, nano-organosilicon polymer and strontium aluminate rare earth material mixing and stirring to be formed absorbs when first time bright dipping, transforms and store, realizes exciting bright dipping under off-position.
The present invention relates to stored energy and change the Luminescent Materials of luminous energy, testing through many experiments: experiment zinc sulphide Rare Earth Material Chemistry formula is ZnS:Cu, decays to below the eye-observation limit after 1 ~ 2 hour secondary excitation bright dipping time; Fluorescent lifetime is shorter, between when experiment strontium aluminate rare earth material inspires light 10 ~ 12 hours, luminous intensity scope: 300mcd/m
2~ 4000mcd/m
2,, strontium aluminate rare earth materials chemistry formula is SrAL
2o
4, particle diameter is 10um ~ 50um, stable chemical performance, high temperature resistant, "dead", nontoxic, experimental result: strontium aluminate rare earth material meets the requirement that secondary excitation goes out luminescent material.
For improving secondary excitation light-out effect further, transparent material need be adopted to have auxiliary material that is reflective or reflective functions, through experiment test: glass microballoon is a kind of environment-friendly materials of transparent material, quality is light, stable chemical performance, refractive index can reach more than 1.8, particle diameter is 20um ~ 50um the most, there is good reflective and refraction effect, nano-organosilicon material is that uniform adsorption reduces precipitation, experimental result: strontium aluminate rare earth material allotment glass microballoon, nano-organosilicon material effectively can improve secondary excitation bright dipping light efficiency.
The present invention's second time excites the light-emitting admixture of bright dipping to allocate ratio through experiment test: strontium aluminate rare earth material mixing ratio is less than 4% secondary excitation and goes out luminous intensity minimizing 10%, when mixed proportion is greater than 6%, then affect the first time light extraction efficiency that blue chip excites the fluorescent glue of silica gel and yellow fluorescent powder mixing and stirring, go out luminous intensity and reduce 15%; Experiment test: glass microballoon mixed proportion is less than 2%, go out luminous intensity after the reflective refraction of secondary excitation and reduce by 20%, also obviously secondary excitation light-out effect is not promoted, experiment conclusion: silica gel, glass microballoon, nano-organosilicon polymer, strontium aluminate rare earth material is the highest in 91% ~ 93%: 2% ~ 3%: 1% ~ 2%: 4% ~ 6% ratio secondary excitation bright dipping light efficiency when mixed proportion is greater than 3%.
Adopt the luminous light efficiency of spectroanalysis instrument test traditional handicraft planar structure LED and the well-illuminated data of light as follows:
In energising, adopt spectroanalysis instrument test identical material condition, the present invention test finished level structure LED first time stimulated luminescence efficiency and luminous flux data as follows:
Adopt illumination tester and timer, the different absorbing time of test planar structure LED product, second time excite the initial luminescence of bright dipping and after 10 minutes luminous intensity data variation as follows:
Under excited state after a loss of power, adopt illumination tester test experience finished product, planar structure LED second time inspires luminous intensity and fluorescent lifetime data are as follows:
From upper experimental data, in the energized state, blue chip excites the fluorescent glue of silica gel and yellow fluorescent powder mixing and stirring to realize first time bright dipping, light is well-illuminated improves 3% ~ 5% with light efficiency than identical material traditional handicraft LED, simultaneously strontium aluminate rare earth material sorption enhanced luminous energy be stored in the lattice of molecular structure, absorbs and stores luminous energy and to reach capacity after 60 minutes state; Under stopping "on" position, the energy stored automatically excites and changes into luminous energy and realizes secondary excitation bright dipping, the bright dipping time can reach 10 hours, secondary excitation bright dipping is after 10 hours, the Conversion of Energy that strontium aluminate rare earth material is stored in lattice runs out of, and luminous intensity can drop to the lower limit of eye-observation degree.
Its packaging technology is comparatively simple, comprises the following steps: preparation second time excites the light-emitting admixture of bright dipping: at normal temperatures silica gel, glass microballoon, nano-organosilicon polymer, strontium aluminate rare earth material are prepared into light-emitting admixture in the ratio mixing and stirring of 91% ~ 93%: 2% ~ 3%: 1% ~ 2%: 4% ~ 6%; Binding chip: support or heat sink on binding chip, with ultrasonic wire welding machine weld metal wire connection bracket and both positive and negative polarity corresponding to chip; Spraying fluorescent glue: the fluorescent glue be mixed to form that yellow fluorescent powder and silica gel stirred sprays to support or heat sink inside cavity, control the quantity for spray of fluorescent glue be inside cavity volume 3/5 ~ 3/4 between; A baking-curing: the product having sprayed fluorescent glue is put into constant temperature roaster 100 DEG C baking 1 hour; Spraying second time excites the light-emitting admixture of bright dipping: excite the light-emitting admixture of bright dipping to spray to roasted rear half-finished cavity dummy section second time, and makes second time excite the light-emitting admixture of bright dipping to form the arc of microprotrusion; Secondary baking solidifies: excite the product of the light-emitting admixture of bright dipping to put constant temperature roaster 100 DEG C baking into after 1 hour good for spraying second time, then improve temperature to 150 DEG C of bakings 3 hours; Epoxy sealing: when support binding chip takes straight cutting frame mode, need adopt epoxy resin by after secondary baking semi-finished product baking 130 degree 1 hour, complete seal protection after solidification; Light splitting is packed.
Packaging technology of the present invention is simple, meet illumination, view brightening demand completely in the energized state, secondary excitation bright dipping time and luminous intensity can be used effectively in the power-off state, and relative energy saving about 40%, its energy-saving benefit and economic benefit are promoted further.
