Description

色溫可調之白光光源
本發明係關於一種色溫可調之白光光源，且特別係關於基於發光二極體配置之光源。而且，本發明提供產生一選定色溫的白光之方法。
如已知，一白光光源之相關色溫(CCT)係藉由將其色調與一理論、加熱黑體輻射器相比較而決定。CCT係以凱式(Kelvin，K)為單位來表示，且對應於放射與光源相同的白光色調的黑體輻射器之溫度。現今，來自一白光光源之色溫主要係藉由用來產生光的機構而決定。例如，白熾光源始終提供約3000K的一相對低色溫，稱為"暖白色"。相反地，螢光始終提供約7000K的一較高色溫，稱為"冷白色"。當購買光源或當完成建築物設計或構造時，可決定暖或冷白色的選擇。在許多情況中(例如街道照明)，暖白色與冷白光係一起使用。
白色發光二極體(LED)在技術中係已知，且係相當最近的創新。直到在電磁光譜的藍色/紫外線部分中發射LED發展之後，其才變成實際基於LED來發展白光光源。如已知，白光產生LED("白色LED")包括一磷光體材料，即一光致發光材料，其吸收由LED發射輻射的一部分，並重新發射一不同顏色的輻射(波長)。典型上，LED晶粒或晶片在光譜的可見部分會產生藍光，且磷光體會重新發射黃光、或綠光與紅光、綠光與黃光、或黃光與紅光之組合。 由LED所產生之可見藍光之部分(不能由磷光體吸收)與所發射的黃光混合，以提供對眼睛呈現白色之光。一白色LED的CCT係由合併在LED中的磷光體組成物所決定。
由於具有長操作壽命(可能多達100,000小時)、及其高效率(從低功率消耗的觀點)，所以白色LED潛在取代白熾、螢光與霓虹燈光源係可預測。最近，高亮度白色LED已用來取代習知的白色螢光、水銀蒸汽燈與霓虹燈。類似其他照明源，一白色LED的CCT係固定，且係由用來製造LED之磷光體組成物所決定。
US 7,014,336揭示產生高品質白光之系統及方法，即具有在人眼之光回應(光譜傳遞函數)中實質上連續光譜之白光。由於眼睛的光回應提供眼睛可見範圍的測量，所以此在具有400 nm(紫外線)至700 nm(紅外線)波長範圍的高品質白光上設定邊界。用於建立白光之一系統包含300個LED，其每一者具有跨越400至700 nm波長範圍之預定部分的一窄光譜寬度與一最大光譜峰值。藉由選擇性控制該等LED之每一者的強度，色溫(以及顏色)可受控制。一進一步照明器具包含9個LED，其在波長範圍上每25 nm具有25 nm之隔開光譜寬度。LED的功率係可調整，其藉由調整9個LED的相對強度以產生多種色溫(以及色彩)。其亦提議使用較少的LED來產生提供之白光，每一LED具有增加的光譜寬度，以維持填滿眼睛的光回應的實質上連續光譜。另一照明器具包含使用一或多個白色LED及提供一光學高通濾波器以改變白光之色溫。藉由提供一連串可互換 濾波器，此致能單光器具藉由指定各種濾波器的一連串範圍以產生任何溫度之白光。
本發明係努力於提供色溫係至少部分可調之白光光源。
根據本發明，一種色溫可調之白光光源包含：一第一發光二極體LED配置，其可操作用以發射一第一波長範圍的光；及一第二發光二極體LED配置，其可操作用以發射一第二波長範圍的光，該等LED配置係組態以致於包含光源之輸出之其組合光輸出會出現白色；其特徵為該第一LED配置包含：一磷光體，該磷光體係遠離一相關聯的第一LED而提供，其可操作用以產生一選定波長範圍的激發能量，及照射該磷光體，以致於其發射一不同波長範圍的光，其中由第一LED配置所發射的光包含來自第一LED之組合光、與來自磷光體所發射的光；及控制構件，其可操作用以藉由控制兩個LED配置之相對光輸出以控制色溫。在本專利申請案的上下文中，"遠離"係意謂在LED之製造期間，磷光體並未合併在LED中。
在一配置中，第二LED配置亦包含一個別磷光體，該個別磷光體係遠離一相關聯的第二LED而提供，其可操作用以產生一選定波長範圍的激發能量，並照射該磷光體，以致於其發射一不同波長範圍的光，其中由第二LED配置所發射的光包含來自第二LED之組合光、與來自磷光體所發射的光，而且其中該控制構件係可操作用以藉由控制該等磷光體之相對照射以控制色溫。
色溫可藉由使用例如一分位器配置來控制該等個別LED的驅動電流之相對振幅而調諧。或者，驅動電流可動態切換，且色溫藉由控制該驅動電流之一負載循環，以控制每一LED發光之相對時間比例而調諧。在此配置中，該控制構件可包含一脈衝寬度調變(PWM)電源供應，其可操作用以產生一PWM驅動電流，其負載循環係用來選擇一所需的色溫。較佳地係，發光二極體係在PWM驅動電流的相反相位上驅動。本發明之特別優點存在於只使用兩個LED配置，由於此致使色溫藉由控制使用簡單及便宜的驅動電路而可輕易實施之兩個相對驅動電流而調諧。
在一配置中，第一與第二LED配置在當這些組合光出現白色之時發射光的不同顏色。此產生白光的配置之優點係改良性能，當相較於該等LED配置各產生不同色溫之白光之配置，特別具有較低的吸收性。在此配置中，磷光體發射綠光或黃光，且第二LED配置發射紅光。較佳地係，用來激發磷光體的第一LED係可操作用以發射440至470 nm波長範圍的光，即藍光。
在一進一步配置中，由第一LED配置所發射的光包含具有2500K至4000K色溫範圍之暖白(WW)光，且由第二LED配置所發射的光包含具有6000K至10,000K色溫範圍之冷白(CW)光。較佳地係，WW光具有(0.44,0.44)的色度座標CIE(x,y)，且CW光具有(0.3,0.3)的色度座標CIE(x,y)。在另一配置中，第一磷光體發射具有(0.22,0.275)的色度座標CIE(x,y)之綠光，且第二磷光體發射具有(0.54, 0.46)的色度座標CIE(x,y)之橘光。較佳地係，用來激發磷光體的LED係可操作用以發射440至470 nm波長範圍的光。
在一進一步配置中，該等磷光體共用一共同激發源，以致於第二LED配置包含一個別磷光體，該個別磷光體遠離該第一LED而提供，而且其中該第一LED係可操作用以產生兩個磷光體的激發能量，且光源進一步包含與每一磷光體相關聯的一個別光控制器，且該控制構件係可操作用以藉由控制光控制器以控制該等磷光體之相對照射以選擇色溫。較佳地係，該光控制器包含一液晶快門，用以控制到達相關聯的磷光體的激發能量之強度。隨著一LCD快門，該控制構件係有利的可操作用以藉由控制該等個別LCD快門的相對驅動電壓以選擇色溫。或者，該控制構件係可操作用以動態切換LCD快門的驅動電壓，且色溫係可藉由控制該電壓的一負載循環而調諧。較佳地係，該控制構件包含一脈衝寬度調變電源供應，其可操作用以產生一脈衝寬度調變驅動電壓。
為了增加光輸出的強度，光源包含複數個第一與第二LED配置，其可為陣列形式之有利組態(例如一方形陣列)，以改良輸出光之色彩一致性。
由於色溫係可調諧，所以本發明之光源可在街道照明、車輛前燈/霧燈、或光源在能見度受到例如溼氣、霧氣、灰塵或煙霧損害的環境操作應用方面找到特別應用。有利地係，光源進一步包含一感測器，用於偵測在光源可操作 的大氣環境中溼氣的出現，且該控制構件係進一步可操作，其可回應該感測器以控制色溫。
根據本發明，一種產生一可調色溫之白光之方法包含：提供一第一發光二極體LED配置，且操作其以發射一第一波長範圍的光；及提供一第二發光二極體LED配置，且操作其以發射一第二波長範圍的光，該等LED配置係組態以致於其組合光輸出會出現白色；其特徵為該第一LED配置包含一磷光體，該磷光體遠離一相關聯的第一LED而提供，其可操作用以產生一選定波長範圍的激發能量，並照射該磷光體，以致於其發射一不同波長範圍的光，其中由該第一LED配置所發射的光包含來自該第一LED之組合光、與來自該磷光體所發射的光，並藉由控制兩個LED配置之相對光輸出以控制色溫。
正如根據本發明之光源，第二LED配置可包含一個別磷光體，該個別磷光體遠離一相關聯的第二LED而提供，其可操作用以產生一選定波長範圍的激發能量，並照射該磷光體，以致於其發射一不同波長範圍的光，其中由第二LED配置所發射的光包含來自第二LED之組合光、與來自該磷光體所發射的光，並藉由控制該等磷光體之相對照射以控制色溫。
該方法進一步包含藉由控制該等個別LED的驅動電流之相對振幅以控制色溫。或者，該等個別LED的驅動電流可動態切換，且該驅動電流的一負載循環可受控制以控制色溫。有利地係，該方法進一步包含產生一脈衝寬度調變驅 動電流，且在該驅動電流的相反相位上操作該等個別LED。
該方法進一步包含：提供與每一磷光體相關聯的一個別光控制器；及藉由控制光控制器以控制該等磷光體的相對照射以控制色溫，其中該第二LED配置包含一個別磷光體，該個別磷光體遠離該第一LED而提供，而且其中該第一LED係可操作用以產生兩個磷光體的激發能量。色溫可藉由控制個別光控制器的相對驅動電壓而控制。或者，光控制器的驅動電壓可動態切換，且色溫可藉由控制該電壓的一負載循環而控制。
根據本發明，一種色溫可調之白光光源包含：一第一發光二極體配置，其可操作用以發射一第一波長範圍的光；及一第二發光二極體配置，其可操作用以發射一第二波長範圍的光，該等發光二極體配置係組態以致於包含光源之輸出之其組合光輸出會出現白色；其特徵為：一感測器，用於偵測在光源係可操作之大氣環境中的溼氣出現；及控制構件，其可操作用以回應感測器來控制兩個發光二極體配置的相對光輸出以設定發白光之一選定色溫。
根據本發明的一進一步態樣，一種色溫可調之白光光源包含：第一與第二發光二極體配置，其包含一個別磷光體與至少一發光二極體，其可操作用以產生一選定波長範圍的激發能量，並照射該等磷光體，以致於每一者發射一不同波長範圍的光，其中由每一發光二極體配置所發射的光分別包含來自發光二極體之組合光、與來自該磷光體所發 射的光，該等發光二極體配置係組態以致於包含光源之輸出之其組合光輸出會出現白色；其特徵為：一可控制光控制器，其與每一磷光體相關聯，且可操作用以控制該等磷光體的相對照射；及控制構件，其可操作用以藉由控制該光控制器以選擇色溫。
參考圖1a，其係顯示根據本發明的一色溫可調(可選擇)之白光光源1之示意圖，其包含第一發光二極體(LED)配置2與第二LED配置3之陣列。在範例中，該陣列包含具有13個第一與12個第二LED配置的25個LED配置的一般方形陣列。應可瞭解，本發明並未侷限於特別數量的LED配置或特別幾何佈局。該等第一LED配置2之每一者係可操作用以發射暖白(WW)光4，且該等第二LED配置3之每一者係可操作用以發射冷白(CW)光5。在此專利申請案中，WW光係具有2500K至4000K色溫範圍之白光，且CW光係具有6000K至10000K色溫範圍之白光。由LED配置2、3發射的組合光4與5包含光源1的光輸出6，且會出現白色。如所述，輸出光6的色溫取決於CW與WW光貢獻之相對比例。LED配置2、3之每一者包含磷光體材料7、8之區域，該區域遠離一相關聯的LED 9、10而提供。LED 9、10係可操作用以產生一選定波長範圍的激發能量11、12，並照射該磷光體，以致於其發射一不同波長範圍的光13、14，且該配置經組態以致於由該LED配置所發射的光4、5包含來自LED之組合光11、12、與來自該磷光體所發射的光13、 14。典型上，LED 9、10包含一藍色/UV LED與磷光體區域7、8，彩色磷光體之一混合物以致於其光輸出會出現白色。
參考圖2，其係顯示操作圖1之光源1的一驅動器電路20之示意圖。該驅動器電路20包含一可變電限器21 Rw ，用以控制第一與第二LED配置2、3的相對驅動電流IA 與IB 。每一LED配置2、3的LED 9、10係串聯連接，且該等LED配置係與可變電阻器21並聯連接。可變電阻器21係組態成一分位器，且用來選擇相對的驅動電流IA 與IB ，以達成一選定相關色溫(CCT)。
圖3係針對選定CCT 2600至7800K的圖1之光源的輸出光強度(任意單位)對波長(nm)之圖式。不同色溫白光係藉由改變驅動電流IA 與IB 的相對振幅而產生。表1表列驅動電流IA /IB 與色溫CCT(K)之選定比率之色度座標CIE(x,y)。
在替代的光源中，第一與第二LED配置2，3係可操作用 以發射不同彩色光4，5(除白色外)，其當組合一起時，包含對眼睛呈現白色之光。在此一光源中，第一LED配置包含一LED配置，其發射具有(0.22,0.275)的色度座標CIE(x,y)之藍－綠光，且該第二LED配置包含一LED，其發射具有(0.54,0.46)的色度座標CIE(x,y)之橘光。再次，輸出白光的色溫係藉由控制該等LED配置的驅動電流之相對振幅而調諧。圖4係分別指示針對第一與第二LED配置之色度座標40、41之光源的國際照明委員會(CIE)1931 xy色度圖。連接兩點40、41之一線條42代表藉由改變驅動電流IA 與IB 的振幅，光源可產生的輸出光之可能色溫。而且，圖4中的指示係由位於美國加州Fremont的Intematix Corporation所製造磷光體之色度座標。圖5係針對一光源之選定色溫之輸出光強度對波長之圖式，其中該第一LED發射具有(0.22,0.275)之色度座標CIE(x,y)之藍－綠光，且第二LED發射具有(0.54,0.46)之色度座標CIE(x,y)之橘光。使用兩個不同色彩LED配置以產生白光之優點係一改良性能，且相較於使用兩個白色LED配置，特別係一較低的吸收性。表2表列包含橘色與藍綠色LED之一光源之驅動電流IA /IB 與色溫CCT(K)之選定比率之色度座標CIE(x,y)。
在另一具體實施例中，第一LED配置包含：一綠－黃色磷光體7，其係藉由放射從440 nm至470 nm波長範圍之藍光之一LED 9所活化；及第二LED配置包含一LED，其發射從620 nm至640 nm波長範圍之紅光。在此配置中，應可瞭解不需要磷光體區域8。
圖6顯示用於操作圖1之光源之一進一步驅動器電路60。該驅動器電路60包含：一個別雙極接面電晶體BJT1、BJT2(61、62)，用以操作每一LED配置2、3；及一偏壓網路，其包含分別表示63至68的電阻器R1 至R6 ，用以設定電晶體61、62的直流操作條件。電晶體61、62係組態成一接地射極e組態之電子開關。第一與第二LED配置係串聯連接在一電源供應VCC 與其個別電晶體的集極端子c之間。可變電阻器RW 7係連接在電晶體的基極端子b之間，並藉由設定電晶體之基極的相對電壓Vb1 與Vb2 而用來設定第一與第二LED配置2、3的相對驅動電流IA 與IB (其中BJT1的IA ＝Ice ，且BJT2的IB ＝Ice )、與光源的色溫。控制電壓Vb1 與Vb2 的關係如下式所給定：
作為使用一直流驅動電流IA 、IB 來驅動LED配置及設定該等驅動電流之相對振幅以設定顏色之替代選擇，LED配置可使用一脈衝寬度調變(PWM)驅動電流iA 、iB 而動態驅動。圖7說明一PWM驅動器電路70，其可操作用以在PWM驅動電流的相反相位(即iB ＝iA )上驅動兩個LED配置2、3。PWM驅動電流的負載循環係輸出為高(標示時間Tm )的一整個循環(時間週期T)之比例，並在時間週期中決定有多長係第一LED配置可操作。相反地，輸出為低(空間時間Ts )之整個時間週期的時間之比例決定第二LED配置係可操作的時間之長度。動態驅動LED配置之優點在於每一配置係在最佳驅動電流上操作，雖然需要選擇時間週期以避免光輸出之閃爍、及當由觀察者觀看時，確保由兩個LED配置所發射的光組合以提供出現白色之光。
驅動器電路70包含一計時器電路71(例如一NE555)，其以一不穩定(自由運行)操作組態，其負載循環係藉由包含電阻器R1 、RW 、R2 與電容器C1與一低電壓單刀/雙擲(SPDT)類比開關72(例如一Fairchild SemiconductorTM FSA3157)之一分位器配置而設定。包含一PWM驅動電壓的計時器73之輸出係用來控制SPDT類比開關72的操作。一電流源74係連接至開關之極A，且LED配置2、3連接在該開關的一相對輸出B0 、B1 與接地之間。一般而言，標示時間Tm 係大於空間時間Ts ，結果該負載循環係小於50%，並如下所給定： 其中Tm ＝0.7(RC ＋RD )C1、Ts ＝0.7 RC C1與T＝0.7(RC ＋2RD )C1。
若要獲得小於50%的負載循環，一信號二極體D1 可加入而與電阻RD 並聯，以在計時器循環的一充電(標示)部分期間將RD 予以旁通。在此組態中，標示時間僅取決於Rc 與C1(Tm ＝0.7 RC C1)，以致於該負載循環係如下給定：
熟諳此項技術者應可瞭解可修改揭示的光源，而不致脫離本發明的範疇。例如，雖然在示範性實施方案中，描述之每一LED配置係包含如在遠離一個別LED晶粒的個別區域上提供的一磷光體，但是在其他具體實施例中，如圖8所示，其可想像成使用一LED 80來照射具有激發能量81之兩個不同磷光體7、8。在此配置中，光源之色溫係不能夠藉由控制LED的驅動電流而控制，且一個別光控制器82、83係提供以控制來自每一LED配置的相對光輸出。在一實施方案中，光控制器82、83包含一個別LCD快門，且該等LCD快門可使用描述的驅動器電路來控制該等快門的驅動電壓而受控制。而且，LCD快門係有利地如同一陣列予以製造，且該磷光體如同在該陣列之LCD快門之表面上的一個別區域予以提供，且覆蓋該陣列之LCD快門之個別者。
本發明的色溫可調之白光光源尋找關於商業與家庭照明應用方面之特別照明配置應用。由於色溫係可調諧，所以當使用在街道照明或車輛前燈時，本發明之白光光源係特 別有利。如已知，一較低色溫之白光可比一相對較暖色溫之白光有更佳穿透霧氣。在此應用中，一感測器係提供以偵測霧氣、溼氣之出現，及/或測量回應最佳化霧氣穿透所調諧之其密度與色溫。
