The second experiment is to fabricate white light LED from red and green phosphors pumped by blue light LED. The blue light LED we used in our experiment has the wavelength range between 450 and 452.5 nm, and the chip size is 17 mil *14 mil. There are two kinds white light LED we fabricated in the experiment. There are three blue light LED chips bonded in single package of both kinds package. The different of the both packages is mixed phosphor of encapsulation. One of the experimental devices was encapsulated YAG phosphor mixed silicone to fabricate white light. The other is red and green phosphor mixed encapsulation. The compared and focused parameter was luminous efficiency. YAG phosphor pumped white light has the luminous efficiency 72 lm/W, CRI 70, CIE(0.32, 0.33), CCT 5622°K at the operating current 60mA. On another hand, red and green phosphor pumped white light LED has the luminous efficiency 55 lm/W, CRI 90, CIE(0.31, 0.32), CCT 6479°K at the operating current 60mA. We fabricated the red and green phosphor pumped white light LED, and proved that it could has much higher CRI under similar compared conditions, CIE xy and CCT.

第二个实验是使用蓝LED晶粒来制作白元件,蓝LED晶粒波段范围在450 ~ 452.5 nm,晶粒大小为17*14 mil,以三颗蓝LED晶粒搭配YAG萤粉(黄绿 540 nm)制成白元件,再以另外三颗蓝LED晶粒搭配红色萤粉(613 nm)混合绿色萤粉(519 nm)制成的白元件进行发效率比较;搭配YAG萤粉的白元件在注入60 mA的电流时所量测到最大的发效率是在72 lm/W,演色性数值大约为70,CIE色度座标为(0.32, 0.33),色温是在5622 °K;而搭配红色萤粉混合绿色萤粉的白元件在注入60 mA的电流时,最大的发效率在55 lm/W,演色性数值大约为90,CIE色度座标为(0.31, 0.32),色温在6479 °K;证明了蓝LED晶粒搭配红色萤粉混合绿色萤的白元件演色性指数可以高达90 以上的结果。

The results were as follows:(1) The spectral sensitivity response at 14 monochromatic light selected through 340nm to 605nm occurred in curve with multiple peaks, the primary peak in 340nm (ultra-violet) is the highest response rate of phototaxis (21%), the secondary in 524nm, and the rest in 400-440nm and 483nm in order;(2) The response rate of phototaxis is increasing as the relative intensity of light, it is showed as curves with inverse "L" shape in white light and the monochromatic light of 483nm, as an upward ladder at 524nm and a near straight line at 340nm. However, the response rate could be detected at the lowest intensity and not arrived to the summit at the strongest yet;(3) The effect of sex to response to the spectral sensitivity and intensity is not significant;(4) There was not significant photophobism response to light for the ladybird, the behavior probably derived from phototaxis or partly due to random movements. It can be concluded that both the spectrum and intensity of light stimulus gave rise to the phototaxis of P.

结果显示:(1)在340~605nm波谱内其谱趋行为反应为多峰型,峰间主次不明显,紫外340nm处峰最高,趋反应率达21%,其它各峰依大小次序分别位于绿524nm、蓝400~440nm和483nm处;(2)随强增强其趋反应率增大,白和483nm刺激时其强趋行为反应呈一倒"L"型式样,524nm时呈一阶梯型,340nm时为一较平直的线型;强最弱时仍均有一定趋率,最强时均未出现高端平台;(3)性别对其谱和强度行为反应均有一定影响,但影响不大;(4)龟纹瓢虫无明显的避反应,其避行为可能是趋行为衍生或其随机活动造成。

Light holds between its hands The white hill and black oaks, The path that goes o, The tree that stays; Light is a stone that breathes By the sleepwalking river, Light: a girl stretching, A dark bundle dawning; Light shapes the breeze in the curtains, Makes a living body from each hour, Enters the room and slips out, Barefoot, on the edge of a knife; Light is born a woman in a mirror, Naked under diaphanous leaves, Chained by a look, Dissolved in a wink; It touches the fruit and the unbodied, It is a pitcher from which the eye drinks clarities, A flame cut in blossom, a candle watching Where the blackwinged butterfly burns; Light opens the folds of the sheets And the creases of puberty, Glows in the fireplace, its flame becomes shadows That climb the walls, yearning ivy; Light does not absolve or condemn, Is neither just or unjust, Light with impalpable hands raises The buildings of symmetry; Light escapes through a passage of mirrors And returns to light: Is a hand that invents itself, An eye that sees itself in its own inventions.

双手拥着白色山峦与黑色橡树林,前行的路,停留的树;是梦游的河旁呼吸的石:一个女孩舒展,一束暗色破晓。勾勒出帘中微风的形状,每时每刻造出一个鲜活的身体,著脚,踩著刀刃;蹑入房间,又溜走;是镜中诞生的女人,裸露在透明的叶底,被目锁定,瞬间消逝;它触摸著果实和无形,眼睛在它的水罐饮著清晰,火焰绽放如花,蜡烛目睹黑翅的蝴蝶燃烧展开被单的折皱与青春期的皱痕在壁炉里芒焕发,它的火焰成影在墙上攀爬,怀恋著长春藤既不赦免也不谴责无公平与不公平而言,用无法察觉的双手举起对称的建筑;在镜子的通道里逃遁返回于:一只发明自己的手,一只在自己的发明中看到自己的眼。

Two series of polyurethane acrylate grafted acrylic resins (Acr-g-TPU-PETA and Acr-gPPU-PETA) self-emulsifying systems are obtained by grafting -NCO group modified polyurethane acrylates with acrylic copolymer prepared from n-butyl acrylate, styrene,βhydroxyethyl methacrylate and acrylic acid The self-emulsifying systems showed Newtonian fluidity with viscosity closed to that of water, the solid contents were around 30% The T〓 of 15~4℃ for dried film before photocuring favored film formation at room temperature DSC and DMA results showed that PU-PETA is compatible with acrylic resin in the grafted resin The TG and dTG curves for Acr-g-PU-PETA samples were substantially different from the corresponding blends, and the brodened dTG peaks for photocured grafted resin suggest that there might be multiple interactions among chain segments The photocued film of the grafted resins self-emulsifying system exhibited good overall properties with polyurethane acrylate grafts ranging from 30% to 50%, and Acr-g-TPU-PETA series showed better properties than Acr-gPPU-PETA series The adhesion of the photocured film was 1~2 grade, impact strength was 50kg-cm and flexibility was 1mm The Shore hardness and the adhesion of the film decreased markedly if PETA was replaced by HEMA as photoactive group due to the lower C=C double bond content in the grafted resin The polyhydroxy amine-linked thioxanthones photoinitiators can be evenly dispersed in self-emulsifying system without color spot appearing in the dried film The films photocured with IV〓~IV〓 generally exhibited higher Shore hardness, gloss and solventresistance than that cured with Irgacure 2959 and did not induce the rusting of the iron substrate Pigmenting with titanium oxide had no effect on the photocuring The polyhydroxy amine-linked thioxanthone IV〓 and IV〓 can be new candidates for the formulation of titanium oxide pigmented photocurable water-borne coatings for their pale-yellow appearance and slight interference with the color of the coatings WB 4759 with high water-solubility coalesced and separated from the dried resin film, and even induced the rusting of iron substrate.

以丙烯酸丁酯,甲基丙烯酸-β-羟乙酯,丙烯酸及苯乙烯合成厂丙烯酸共聚树脂,并与含-NCO端基的聚氨酯丙烯酸酯接枝反应,经水性化后,得到两个系列(Acr-g-TPU-PETA和Acr-g-PPU-PETA)各5个不同配比的丙烯酸树脂接枝聚氨酯丙烯酸酯自乳化体系,粘度与水相近,为牛顿流体,固含量30%左右。固化前干燥涂膜的玻璃化转变温度在-15℃~4℃之间,有利于室温下成膜。DSC及DMA谱表明两种树脂基本相容。Acr-g-PU-PETA的热失重行为明显不同于共混材料,接枝样dTG峰明显宽化,表明接枝样中链段之间的相互作刚有多重性,丙烯酸树脂与聚氨酯之间有一定的相容性。接枝树脂自乳化体系固化涂层的综合性能以聚氨酯丙烯酸酯成分为50%~30%者相对较好,且以Acr-g-TPU-PETA系列更理想。固化膜的附着力为1~2级,冲击强度为50kg·cm,柔软性多为1mm。以HEMA代替PETA作为接枝树脂的活性基团,碳—碳双键密度太低,固化膜交联点太少,硬度和附着力均较差。多羟基胺连硫杂蒽酮引发剂能均匀分散于树脂自乳化体系和接枝树脂干膜中,不出现色斑,固化膜肖氏硬度一般高于以Irgacure 2959为引发剂的固化膜,泽度及耐丁酮溶剂性能均有所提高,不会诱导铁基生锈,钛白着色对固化结果几乎没有影响。本论文所合成的多羟基胺连硫杂蒽酮引发剂IV〓与IV〓为浅黄色,对固化涂层的颜色干扰较小,为配制钛白着色固化水性涂料提供了新的引发剂。水溶性太强的WB 4759在干膜中易聚结析出,且对所附着的铁基有诱导锈蚀作用。
