Description
201221834 六、發明說明: 【發明所屬之技術領域】 本發明係關於照明裝置,其包含: -凹面反射器,其以外邊緣鄰接光發射窗,該反射器及該 光發射窗構成反射器腔之邊界,且該反射器具有面向該光 發射窗之反射性表面; -燈固持構件,其用於容納光源且提供於反射器腔之邊界 處或邊界内。 本發明進一步係關於包含根據本發明之至少一照明裝置 的燈具。 【先前技術】 自US578255 1已知此照明裝置。已知之照明裝置為以背 面安裝至曱板的燈具。充當反射器且可以習知遮板光學設 備產生辦公室光束的聲罩提供於該燈具之背面處。該聲罩 被製造使得其允許聲音穿過至提供於該聲罩與甲板中間的 吸收毯。為此,聲罩係由有孔金屬材料或模製高密度玻璃 纖維材料製成。聲罩及吸收毯由此形成光學元件與聲學吸 收元件之堆疊。此情況使已知之燈具具有相對昂貴、涉及 費力的安裝,及具有相對複雜且相當龐大的構造之缺點。 【發明内容】 本發明之一目標為提供如起首段中所描述之類型的照明 裝置,其中上述缺點中之至少一者得以抵消。為了達成 此,如起首段中所描述之類型的照明裝置的特徵在於反射 器由聲學吸收材料製成。因為相同元件用於反射光及吸收 158994.doc 201221834 聲音兩者’所以相比於具有經堆疊之光學及聲學元件之習 知解決方案,達到大小、厚度及/或寬度及成本的減小。 原則上’任何光反射性、聲音吸收材料可應用於形成反射 器’例如纏繞在硬質框架周圍且由硬質框架攜載之棉絮。 然而’較佳地,聲音吸收材料應具有對於反射器為典型之 性質’亦即對光之高反射性、足夠的機械強度、耐熱及/ 或耐燃等》在此方面,耐熱意謂如此之材料應能夠在3 〇天 期間耐受住至少l20t:之連續使用溫度,且在此方面,耐 燃意謂如此之材料不使火焰蔓延。詳言之,聲音吸收材料 較佳足夠硬質以(例如)不會歸因於其自己之重量而變形, 且足夠硬質以能夠攜載(小的)光源,且遍及其壽命在指定 的熱及環境條件下維持其預成形光學形狀。 較佳地,反射器為漫反射的,或至少具有一高漫反射組 件’例如在此點上反射器為大於7〇%或8〇%或較佳%%的 或為更加漫反射的及/或小於3〇%或2〇%或5%或甚至更小鏡 面反射的。漫反射器允許多孔、開放或粗糙的結構,相比 於更好地適用於用作鏡面反射表面的封閉、平滑表面,其 更好地適用於吸收聲音。此外,漫反射性表面降低眩光的 風險,此在辦公室照明中及對於與電腦一起工作而言尤其 重要,且改反射性表面在(諸如)要求用於聚光照明之精確 光束稍稍較不關鍵的環境中尤其合適。然而,若鏡面反射 性表面為所要的,則可以反射性金屬塗層(例如,鋁塗層) 塗佈聲學吸收材料。對於半鏡面反射性反射器,經打磨、 白色塗料之塗層在聲音吸收材料上為適當的。 158994.doc 201221834 具有上述性質中之至少一者的已知材料為:來自BASF 之Basotect®,即由三聚氰胺樹脂製成之可撓、輕重量、 吸收聲音的開放氣室式發泡體’其為取決於所塗覆塗層具 有約大於85°/。之反射率的熱固性/熱可成形聚合物;及來自 Gore之GOREtm DRP®反射器材料,即由具有約大於99%之 反射率之耐久、非變黃聚合物PTFE(聚四氟乙烯)製成的微 孔結構。 反射器可成整體,但或者反射器可由一起形成凹面反射 器之若干反射器部分構成,例如各自具有以拋物面方式脊 曲之橫截面的兩個相對置放、狹長反射器半部,或具有圓 周直線形凸緣的彎曲、杯狀中心部分。可(例如)藉由橋接 元件或藉由安裝有反射器部分之外殼將若干部分固持在一 起。橋接元件或外殼可同時充當一構件以固持燈固持構 件’及固持連接器構件以將照明裝置連接至主電源供應 器。在本發明中,表述「燈固持構件提供於反射器腔之邊 界處或邊界内」包含該固持構件(視情況連同光源)形成反 射益腔之邊界之部分及/或提供於反射器腔内部的彼等實 施例。 反射器之凹面形狀具有光學及聲學益處兩者:在光學 上’其有助於產生所要截止’使得不可在小於所要、特定 角度之角度下檢視到明亮光源;且在聲學上,自空氣至吸 收材料,反射器之凹面形狀降低聲學阻抗步階。結果,相 比於平面、扁平板,材料反射較少聲波,且更多聲音被吸 收。此益處尤其適用於反射器之陣列。又,此益處對於具 158994.doc
S 201221834 有可與個別反射器大小比較或更大之波長的聲波而言最顯 而易見p相比於平面、扁平形狀,凹面形狀之另一益處在 於所反射聲音在空間中更加散射。此亦改良聲學效能,此 係因為擴散之聲音較不可辨且並非清晰地來自單一方向, 如較少干擾一樣經歷此情況。 反射器之光學反射側較佳為凸面的,但背面未必為凹 面,亦即背面可具有任何形狀,例如波狀或扁平。具有較 大體積之吸收材料對於聲學吸收而言為有利的。因此,較 佳燈具中之所有空的空間填充有聲學吸收材料。聲學材料 了具有值疋厚度,但或者情況並非如此:除了需要用於光 源及驅動器之空間以外,整個外殼可經填充以改良燈具之 聲音吸收特性,但必須尋求在一方面之照明裝置之重量及 成本與另一方面的照明裝置之聲音吸收特性之間的平衡。 照明裝置之一實施例的特徵在於反射器為楔形的且包含 互連反射器的寬度Woe之窄端與寬度Wie之寬端的邊緣壁、 楔形反射器之高度Η為實質上平行於楔形反射器之軸a所 ϊ測的尺寸,且Wlw、界。6與Η之間的關係係根據以下方程 式: tan(a)<=(Wlw+Woe)/2H,其中 α為 <=65。。 a為在垂直於光發射窗之軸八與光源及/或高照度表面經 由光發射窗不再可見處之線之間的(截止)角度。較佳地, 光源包含配置於楔形反射器之窄端處的發光表面,該發光 表面面向光發射窗且具有實質上等於楔形反射器之窄端之 尺寸的尺寸,且用於向楔形反射器之寬端發射實質上漫射 15&994.doc 201221834 光°光源接著封閉窄端,由此抵消光可洩露通過之光學間 隙的可能性’且另外啟用光強度之較低峰值同時相同量之 光仍可自照明系統發出。眩光截止接著由凹面反射器之高 度結合側發射源之光束輪廓來判定。反射器應阻擋對此光 束之直視°給定最小高度值呈現可接受地低之照明系統之 眩光值。 模形反射器之軸通常經配置以便自窄端之中心延伸至寬 端的中心,且(例如)與照明系統之光軸重合。該軸與光發 射窗交叉;該軸與該光發射窗之間的交叉可為(例如)實質 上垂直的。楔形反射器可具有截頭圓錐形狀或截頭金字塔 形狀或任何其他形狀。寬端及/或窄端之邊緣與光發射窗 之間的交叉可為圓形、橢圓形或多邊形的。尤其具有橢 圓或矩形形狀之交叉的楔形反射器在走廊照明中可為有用 的,其中可使光束輪廊不對稱以增強壁照明(例如,寬光 束至壁’窄光束平行於壁以避免眩光),或相&,可使光 束朝壁方向較窄以節省能量’且沿走廊方向較寬以增大燈 具間距及節省成本。邊緣壁由(漫)反射材料製成,該反射 :料具有嶋至99.5%的反射率。根據本發明之楔形反射 裔可以頸狀物在其窄端處之方式或無頸狀物在其窄端處之 方式得以體現;窄端可為開放或㈣的1中後者情況下 楔形反射器為凹面反射器杯。 低爆+赞 光 常 —π仍座玍符 要求之照明系統的解決方案為相對有成本效兴的 ,在已知之照明系統中’稜鏡板/片用以限制眩光 158994.doc
S 201221834 此等稜鏡片相對昂貴,且在已知之照明系統中應用稜鏡片 相對昂貴。又,置放遮板以用於限制(例如)螢光光源之眩 光相對耗時且由此相對昂貴。可(例如)由高漫反射性發泡 體以相對有成本效益的方式製造楔形反射器,且使用(例 如)熱成形製程使楔形反射器成形。模形反射器可配置於 光源周圍以用於以相對低之成本產生具有有限眩光值的照 明系統。 照明裝置之一實施例的特徵在於其包含藉由邊緣壁、窄 化及提供於反射器腔中並橫斷軸而延伸的光學元件定界的 混合腔室。因此,來自複數個led(例如,藍色、綠色、紅 色、琥轴色或白色之發射LED(形成光源))之光在自照明裝 置發出之前得以混合。光學元件可為折射元件以重定向來 自光源之光,或可為透鏡以產生特殊光束圖案,或可具備 發光材料,及/或光學元件為散射元件。此後者實施例之 益處在於光源與散射元件之組合允許選擇由照明裝置發出 之光的漫射程度。可藉由(例如)以一個散射元件替代另一 散射元件來調適散射程度。散射元件之使用允許光學設計 者調適(例如)楔形反射器之最小高度。散射元件可包含用 於漫散射來自光源之光的漫散射構件。歸因於此漫散射構 件,光源之亮度降低以防止使㈣在看向照明系統中時被 光致盲/曼放射構件可為部分漫反射性且部分漫射性半透 明的漫射體板、漫射體片或漫射體。離散咖(各自發出 特定光譜之光)之可見度,&因此非均一光之可見度由此 有效地得以抵消。 15S994.doc 201221834 散射元件可包含用於漫散射來自光源之光的全像散射結 構》相比於其他已知之散射元件,全像散射結構之效率高 得多’從而允許自光源發射漫射光,同時維持相對高效之 光源。高效通常係歸因於全像散射結構之相對低之背散 射。 若光學元件包含嵌入於光學元件中或塗覆至光學元件之 表面的發光材料,則該發光材料可有益地用以藉由將由光 源發射之光轉換至不同色彩之光來調適由照明系統發射之 光的色彩。舉例而言,當光源發射紫外光時,光學元件可 包含發光材料之混合物,該等發光材料各自吸收紫外光且 將紫外光轉換至可見光。發光材料之特定混合物提供預定 義感知色彩之光的混合物.或者,光源發射可見光(例 如,藍光)’且藍光之部分由發光材料轉換成較長波長之 光(例如,黃光)。當與藍光之剩餘部分混合時, 彩之光(例如,白光)可產生。 義色 尤其,當將發光材料之塗層或層塗覆至面向光源之光學 元件表面_ ’自⑯明系統之外部並非立即可見發光材料^ 塗層或層。在光源發射藍光’該藍光之一部分由發光材料 轉換至黃光的實例中,執行此轉換之發光材料的色彩經感 知為黃色。當自照明系統之外部可見發光材料時,此黃色 發光材料(例如,其可為發光材料:YAG:Ce)之視覺可能不 爻照明系統之製造者青睞,此係因為其可使該照明系統之 使用者混淆,從而使該等使用者認為該照明系統發射黃 光。因此,當在面向光源之光學元件表面處塗覆發光材料 158994.doc
S -10- 201221834 時自外。P不可直接見到該發光材料,由此減少光學元件 之黃色外觀且因此減少對照明系統之使用者的混淆。此 外,當不曝露至環境時,發光材料之塗層(例如)由到或擦 而受損傷的風險降低。 如由照明系統發射之光束的形狀尤其取決於楔形反射器 之形狀°可使用(例如)光學模型化軟體(亦被稱為光線追縱 釭式’諸如LightTools®)來判定產生特定預定義光束形狀 之楔形反射器的形狀。出於此㈣,照明裝置之一實施例 的特徵在於邊緣壁沿軸彎曲以用於調適由照明系統發射之 光的光束形狀。在照明裝置之一實施例中,光源之發光表 面朝向楔形反射器之寬端凸面成形。此等凸面成形之發光 表面的益處在於此等發光表面可由具有(例如)朗伯 (Lambertian)光分佈的光源(例如,發光二極體)更均一地照 明。此改良之均-性進—步降低由光源發射之漫射光的亮 度’藉此進一步降低眩光。 凸面成形之發光表面的另一益處在於其為光源提供空 間,此使製造根據本發明之照明系統變得容易。當光源為 (例如)發光二極體時,該發光二極體通常應用於諸如 之電路板。此PCB可用以安裝楔形反射器及凸面成形之發 光表面兩者,由此增強製造照明系統之容易性。另外,凸 面成形之發光表面可在其反面為用於光源之驅動器電子嗖 備提供空間。 & 在照明系統之一實施例中,邊緣壁朝向楔形反射器之對 稱軸向内彎曲以用於調適由照明系統發射之光的光束形 15S994.doc 201221834 狀。此向内彎曲之邊緣壁的益處在於65度處之炫光值得以 顯著減小。相比於具有實質上直之邊緣壁的照明系統,此 減小之炫光值允許在具有向内彎曲之邊緣壁的照明系統中 引入較高的光通量,同時仍觀測到正常眩光。針對邊緣壁 所要求之精確曲率可取決於光源之發光表面的形狀及大 小,且可使用(例如)光學模型化軟體(亦被稱為光線追蹤程 式,諸如ASAP®、LightTools®等)來判定該精確曲率。 在另一實施例中,照明裝置之特徵在於燈固持構件提供 於反向反射器與反射性表面中間。反向反射器可經選擇, 使得在操作中照明裝置充當基本上單獨地以間接方式發出 光的燈具,亦即來自光源之光在(漫)反射之後基本上僅自 燈具發出。反向反射器之效應為雙重的,亦即,首先其阻 擋由觀測者經由光發射窗對光源之直視,及其次由光源發 射且直接衝擊反向反射器之光在該反向反射器内反射抑或 在經由光發射窗發出至外部之前反射至反射器。因此,眩 光之風險降低。 較佳地,照明裝置之特徵在於反向反射器係由聲學吸收 材料製成。因此,照明裝置之有利性質(亦即,聲音吸收) 知以維持。用以保持相互定位之反射器與反向反射器的明 冬方式為藉助於橋接元件,該橋接元件視情況同時亦可保 持經定位之多個反射器部分與燈固持構件且形成用於光源 之驅動器電子設備的外殼。反向反射器之邊可形成光發射 窗之界限之部分。反向反射器可完全或部分地提供於反射 器腔中,在此情況下,反向反射器位於燈固持構件與光發 158994.doc
