Abstract
一種LED系統，其包含經密封之內部體積，其含有對揮發性有機化合物(VOCs)之存在敏感的一種或多種元件，其中在該內部體積中存在著用於去除VOCs的吸氣劑組成物，其包含至少兩種不同類型之沸石的組合。
Description
本發明其本身為LED系統，其含有用於去除揮發性有機化合物(VOCs)的吸氣劑組成物。
已知LED是光電裝置，其利用一些半導體材料的光學性質，藉由電子-電洞再結合來產生光子。電子和電洞係從兩個區域注入再結合區，一個含有用於電子的n型摻雜物，另一個含有用於電洞的p型摻雜物，以實現所謂的p-n接面。
LED之光發射係藉由半導體材料及/或一種或多種發光材料(磷光體)來加以確定和界定，該等發光材料各自在可見光譜之經明確界定區域中發光，藉由適當地組合該等材料可實現不同顏色。舉例而言，可藉由組合紅光LED、綠光LED及藍光LED來獲得白光，或者是可使用單一藍光/UV光LED來激發相鄰的磷光體，其將在更長波長處再度發光，透過這種方式，具有磷光體的單一LED可擁有並展現出適當的色譜，諸如：黃光或黃光和紅光，其與來自LED的藍色發光結合而提供白色光。
基本上，LED係由分佈著磷光體的半導體材料(通常稱為「管芯」)薄片所構成，該薄片係經連接至用於電力供應和熱散逸的適當結構。
接著藉由聚合密封劑來保護管芯，且通常將此系統稱為LED封裝。
用於本發明之目的，術語「LED系統」包括安裝在傳統基板上並用聚合樹脂封裝的簡單LED封裝，以及也包括由LED封裝和額外組件所組成的照明裝置，該額外組件諸如：散熱器、反射器、漫射器、燈泡或外部管殼(external envelopes)。
這些LED系統的共同特徵為氣密密封，即該系統並不具有對外部環境之直接開口或通道，不同於以申請人名義進行提交之國際專利申請案WO 2016/181293中所揭示者。
相對於傳統光源，LED系統展現增強的發光和更長的操作壽命，但可能遭遇到性能衰減並出現可靠度問題，其係由於存在著揮發性有機汙染物，其可藉由以下材料來進行釋放：封裝材料及/或其它材料，諸如黏著劑(特別是基於環氧樹脂的黏著劑)、密封材料、填料、焊膏、溶劑殘留物、塗料及墊料。除了這種內部污染源之外，VOCs還可以透過滲透而從外部環境進入LED系統。
在氣密密封的LED系統中有相對高的工作溫度，其在最常見的系統和構造中在60℃和120℃範圍內。
在這種操作條件下，操作期間內所產生的VOCs被捕獲在系統內，或者是它們釋放的動力非常緩慢；結果就是它們會在密封的LED系統內擴散，造成封裝材料的顏色改變和透明度損失，導致光通量的性能降解和顏色偏移。
為了克服這些問題，LED製造商試圖在最大程度上避免使
用VOCs釋放材料，但這導致了在LED系統之設計和製造上的限制，舉例而言，藉由使用特定類型的PCBs(印刷電路板)，生產該系統可能會相當昂貴。此外，在LED的使用壽命期間，不可能完全避免這些物質的滲透和釋放，即使在其實際使用之前、被放在架上時，仍將會遭遇到逐漸衰減。
可在以下來自Vossloh-Schwabe的應用說明中找到VOCs之有害影響和降解機制的更多細節：「Chemical Incompatibilities affecting LEDS」，目前可從以下網路位址中檢索到它：https：//www.vossloh-schwabe.com/fileadmin/user_upload/Download/Produkte/Chemical_Incompatibility_EN.pdf
用於處理電子裝置中之VOCs污染物的解決方案經描述於美國專利申請案2004/0127358中，其描述了使用沸石來作為用於去除有害有機蒸汽的合適材料，其與氧清除劑結合使用，而國際專利申請案WO 2016/154156同樣揭示了使用沸石來作為去除污染物(包括VOCs)的合適材料。此外，美國專利申請案2005/0230691揭示了一種密封的LED系統，其具備一種整合吸氣劑，其含有用於去除氧、水及其它污染物(雖然沒有特別強調VOCs)之沸石。
LED系統中最常見的VOCs污染物為甲苯、苯、二甲苯、庚烯、庚烷、十二烷、十一烷、它們的烷基(例如甲基)衍生物、矽醇及其烷基衍生物、醚、酮、醛及胺。
本發明的目的為提供一種能夠克服這些問題的LED系統，並提供一種用於去除LED系統中之VOCs的改善解決方案，且在其第一態
樣中包括一種LED系統，其包含經密封的內部體積，其中在該內部體積中存在著用於去除揮發性有機化合物(VOCs)的吸氣劑組成物，該用於去除VOCs的吸氣劑組成物包含沸石材料組合，其中該沸石材料組合的一種組分係選自一或多種反式絲光沸石骨架(MFI)、八面沸石13X及絲光沸石，且該沸石組合含有林德A型(LTA)沸石，其量包含在4wt.%和25wt.%之間。
較佳地，在用於去除VOCs之該吸氣劑組成物中，不同沸石的量係藉由下列公式而獲得：
(MFI)x+(八面沸石13X)y+(絲光沸石)z+(LTA)d其中指數x、y、z及d為在用於去除VOCs之吸氣劑組成物中沸石類型的wt.%，且其中：˙x包含在0和80之間、˙y包含在0和90之間、˙z包含在0和60之間、˙d包含在4和25之間，˙以及x+y+z+d為100。
必須強調並理解，上述定義和公式並未排除LED內部體積中存在著其它化合物/材料，且這些範圍因此定義並提出了LTA沸石(對於本發明之目的和效用而言，其存在是有強制性的)相對於先前所詳細指名的其它類型沸石的重量比，以及沸石材料組合中其它類型的沸石的重量比。
發明人已發現到相對於美國專利申請案2004/0127358中所描述的沸石一般用途而言，根據本發明之吸氣劑材料具有更高的VOCs容量。
基於本發明之目的，沸石較佳具有大於700m2/g的表面積和等於或大於4埃的孔洞大小。
沸石的平均尺寸較佳為小於200μm，甚至更佳為小於100μm。對於非球形粉末而言，該尺寸是指最大顆粒大小，且該值係經用於平均測定。也可使用次微米大小的沸石，其經定義為所具有的分佈為90%的顆粒有著等於或小於1μm(X90<1μm)尺寸之沸石，其，即使性能的改善會被相關的複雜性增加和更高成本給抵消。
較佳地，在每單位自由內部體積中之吸氣劑組成物的量包含在0.04mg/cm3和0.60mg/cm3之間，且更佳地包含在0.06mg/cm3和0.40mg/cm3之間。該自由內部體積係經定義為密封LED系統中無組件/材料的內部體積，即保持在真空中，或者是經填充合適氣體或氣體混合物之LED系統的部分。
如國際專利申請案WO 2015/053706中所述，在LED系統中嵌入將與本發明之吸氣劑解決方案結合使用的VOCs氧化化合物，其可能是有用的。
可利用兩種機制來藉由合適的材料使VOCs氧化。在一種情況下，VOCs氧化化合物為氧分配劑(oxygen dispenser)，且VOCs也由於LED系統內的高溫而被氧化。在這種情況下，較佳的釋氧組成物係選自以下之一或多種：MgO2、MgxZnyO2(其中x+y的總和=1)、CaO2、ZnO2、Li2O2、
Na2CO3：1.5H2O2、NaBO3：nH2O、KMnO4及Ca(MnO4)2。
另一VOCs氧化機制設想到的是使用促進在材料其本身表面上之VOCs反應的氧化物。在這種情況下，較佳的氧化材料為CuO、ZnO、MgO、Li2O、TiO2、MnO2及PdO。在這兩種情況下，在LED系統的每單位自由內部體積中，VOCs氧化化合物的量係有利地包含0.05mg/cm3和2.0mg/cm3之間，較佳在0.15mg/cm3和1.5mg/cm3之間。
由於VOCs與額外氧化化合物(其為氧分配劑或具有表面反應機制的氧化物)的反應將產生水，因此有用地也存在著0.03mg/cm3至1.5mg/cm3的CaO量。
在一個替代性具體實例中，根據本發明的吸氣系統係與釋氫材料一起使用。在每單位的自由內體積中，該釋氫材料係以包含在0.05mg/cm3至1.0mg/cm3之間的量存在著，且其較佳選自LiH、NaH、MgH2、CaH2、LiAlH4、LiBH4、NaAlH4、TiH2、ZrH4、YH2、ZrCr(2-x)Mn(x)H2(其中x包含在0和2之間)、LaNi(5-y)AlyH(6+z)、LaNi(5-y)SnyH(6+z)(其中y包含在0和0.25之間、z包含在0和0.5之間)及它們的次化學計量(sub-stoichiometric)化合物。
考慮到可從釋氫材料所放出之氫的高導熱性，這類解決方案有利於改善LED系統的熱散逸。必須強調的是，這類解決方案排除了VOCs氧化化合物的同時存在。這兩種解決方案(VOCs氧化化合物或釋氫化合物)能實現兩種不同的效果，並經擇一用於不同的情況：在第一種情況下，在除去VOCs時有協同效應，其對於處理LED系統中VOCs的產生/滲透之可能的瞬變(transients)和湧現(upsurges)是有用的；而第二種解決方案則改善了
導熱性，並在以下情況時被採用是最有用的：當需處理之經預見VOCs產生並未改變或至少低於某一門檻時。
必須注意的是，這些額外材料係視情況存在的，且可設想根據本發明之LED系統僅使用吸氣劑組成物來去除VOCs，因為根據本發明之LED系統的主要優點為，確保有效地去除存在於LED系統之內部體積裡的VOCs，以防止由於顏色變化和透明度損失所導致的照明性能衰減。
根據本發明之LED系統所提供的另一相關優點為選擇所採用材料的自由度，而不需考慮隨著時間過去，VOCs完全不見或VOCs的釋出及VOCs的滲透機制，以至於該系統能更可靠、簡易，且同時製造起來較不貴。特別是在一些LED系統中，可從所使用的材料中釋放特定的化合物(諸如矽烷醇或矽氧烷)，且對它們的性能會具有不利的影響。
舉例而言，在也被稱作雷射二極體封裝的LED雷射封裝中，不希望存在以下物質：矽氧烷，諸如揮發性甲基矽氧烷、六甲基二矽氧烷、羥基三甲基矽烷、六甲基環三矽氧烷、八甲基環四矽氧烷、十甲基環五矽氧烷、十二甲基環六矽氧烷及其它低分子量的矽氧烷(分子量低於一千amu)，且採用本發明中所述之吸氣劑材料有利於將它們去除，以便維持低程度的污染。
吸氣劑材料的合適結構為呈粉末形式，其本身在容器中經壓縮。此等結構之實例係為熟諳此技藝者所習知，且可在皆以申請人名義的歐洲專利案1851783和2408942中被找到，並透過引用形式將其教示併入本文中。在一個替代性具體實例中，可在容器中將該吸氣劑材料粉末與作為保持助劑的無機材料(其量有用地包含在20wt.%和80wt.%之間)進行混合
和壓縮，該無機材料較佳係選自以下一或多種材料：Cu合金、Sn合金、高嶺石黏土及蒙脫石黏土。另一合適的幾何結構係為美國專利6169361中所示者，在此案例中僅僅關係到氧分配解決方案，但也可有效地將此結構用於本發明。
或者，可用獨立(或自立)壓縮粉末形式來使用吸氣劑材料。在這種情況下，較佳的形狀為丸劑或錠劑，且也可在歐洲專利案2408942中找到這種情況的額外細節。在此結構的替代性具體實例中，藉由無機基質來保留吸氣劑粉末，該無機基質以大於50wt.%、較佳包含在60wt.%和90wt.%之間的量存在。用作保留基質的合適無機材料較佳係選自以下一種或多種：Cu合金、Sn合金、高嶺石黏土及蒙脫石黏土。
吸氣劑材料的另一較佳結構為分散在合適聚合基質中的粉末形式，或者是包含在氣體可滲透聚合管殼中的粉末形式。較佳的基質和聚合管殼材料係選自高密度聚乙烯(HDPE)、低密度聚乙烯(LDPE)、聚丙烯(PP)、聚苯乙烯(PS)、聚對酞酸乙二酯(PET)及聚氯乙烯(PVC)。這類吸氣劑材料結構之解決方案係為習知的，且經描述於例如皆以申請人名義的國際專利申請案WO 2007/066372和WO 2008/148781。
或者，可在合適的載體條上施加活性組成物，該載體條較佳為金屬條。在一個較佳的具體實例中，該活性組成物分散在聚合基質內，例如在聚酯環氧樹脂、環氧丙烯酸樹脂、丙烯酸樹脂、聚胺甲酸酯樹脂、矽氧烷基質、聚矽氧潤膏、聚醯亞胺及聚醯胺樹脂內，且較佳在沉積並黏附於載體上的聚矽氧基樹脂內，如以申請人名義的歐洲專利案1595930中所述。
一般來說，本發明包括以下事實：使用粉末本身，但也可有利地使用、合適地分散該粉末，以及藉由合適的化學試劑(黏合劑)或藉由合適的固化處理來黏結該粉末，例如熱處理，諸如燒結。
假如根據本發明之LED系統中存在著視情況(且相互排斥)的VOCs氧化化合物或H2分配材料，可將此等化合物和材料與吸氣劑組成物加以混合，或者是將其分開放置在LED系統的不同部分/區域中。
本發明並不限定於任何特定的LED系統，尤其是根據本發明之LED系統裝置有兩種主要的類型，第一種裝置在發光裝置中，諸如燈；第二種裝置則在光驅動裝置中，諸如雷射二極體系統和封裝。
將在以下非限制性實施例的幫助下進一步說明本發明，該實施例對樣品之甲苯吸附的相對性能進行鑑定，該樣品由金屬環所組成，其含有表1中所詳述之組成物的壓製粉末混合物，其中使用根據本發明所製備樣品S1〔(MFI)20+(八面沸石13X)45+(絲光沸石)20+(LTA)15〕來作為參照。
已進行以下特性化試驗：藉由微量天平來測量維持在1mbar固定壓力和室溫下的甲苯吸附容量，對本發明中所包括的樣品(S1-S3)，還有不包括在本發明中的三個比較實施例(C1-C3)進行該試驗。
在表1中，用語「可比擬」表示相對於參照S1，在±7,5%內的容量差；「較差」表示相對於S1，從10%到30%的容量減少；「基本上較差」表示相對於S1，等於或大於30%的容量減少。
可觀察到的是，根據本發明之組成物S1-S3具有可比擬的容量，而三個比較實施例C1-C3(具有在本發明範圍之外的LTA沸石wt.%，C1和C3較高、C2較低)則在去除甲苯的總容量方面都具有變差之性能。
