根據發光二極體的至少一實施例,發光二極體包含載 體。載體係為例如平板的形式。也就是說,載體的橫向延 伸程度係大於其厚度。載體具有安裝面,其提供用於發光 二極體之固定元件。 根據發光二極體的至少一實施例,發光二極體包含至 少二個發光二極體晶片。發光二極體較佳地包含大量的發 光二極體晶片,例如四或多個發光二極體晶片。發光二極 體的發光二極體晶片係提供在操作期間,產生頻帶為紅外 線輻射至紫外線輻射之電磁輻射。發光二極體晶片在此例 子中表示發光二極體的光源。較佳地,發光二極體本身發 射白光。 根據發光二極體的至少一實施例,至少二個發光二極 體晶片(較佳地為發光二極體的所有發光二極體晶片)係至 3 95252 201205771 ==該縣:面固定至該載體上。至少間接的意思表系 如中;光一極體晶片與安裴面之間有另-材料,例 如中間载體或例如黏著劑或鋅料的連接裝置。 辦」艮光二極體的至少一實施例,载體具有金屬基本 一乂 ^益屬基本體接著形成载體之主要部分 。例如, ^屬^體佔據倾至少9Q%的體積及重量。金屬基本體 、、良好I傳導性以及熱傳導性的金屬形成,例如銅。 4 ”體包含外部表面,其包含載體的安裝面。也 體之金屬基本體之外部表面的至少-些點形成 _ ^π +而至夕一個發光二極體晶片係至少間接地於該安 裝面固定於載體。 根據發光一極體的至少一實施例,二個二 地為發光二極體的所有發光二極體晶片)係以 並聯的方式彼此電性連接。 :據發光二極體的至少—實施例,發光二極體包含具 面以及至少二個發光二極體晶片的載體,發光二極 載體包含金屬基本體ϊΐί岐至載體。在此例子中, 面。發光二極體的至少錢之絲面的外部表 以並聯的方式彼此連接發光二極體晶片於此例子中係 構相::礎匕:::外’此處所述之發光二極體係以下列 此二ϋ凰装士x光一極體的發光二極體晶片設置成盡可 二ίί 能使在操作發光二極體期間,由發光 -玉日日>i產生特別有效的散熱 。換句話說,發光二極體 95252 4 201205771 晶片所產生的熱係在熱產生之後能盡快地分佈於金屬基本 體的整個體積上,而金屬基本體係形成載體的主要部分。 根據發光二極體的至少一實施例,發光二極體於載體 中包含至少一開口。在此例子中的開口自載體上侧延伸至 載體下側,下侧係面向遠離上側。例如,開口自載體頂面 延伸至載體底面。開口較佳地完全通過載體。開口可為載 體中例如鑽孔的形式,或者開口已於載體製造期間提供。 開口具有内表面,載體材料在該内表面鄰接開口。在此例 子中,内表面係被電性絕緣材料覆蓋。例如,開口的整個 内表面係以電性絕緣材料塗佈,結果是載體材料之開口内 沒有點是暴露的。 例如,開口係用以容納用來安裝發光二極體之固定裝 置。例如,固定裝置可為用以壓合(press f i t)的螺絲或者 定位銷。 用以覆蓋開口之内表面之電性絕緣材料係為例如電性 絕緣塑膠或者藉由例如二氧化矽或氮化矽之電性絕緣材料 形成的層。此外,電性絕緣材料可為陶莞。電性絕緣材料 可含有氮化硼或由例如氮化硼所組成。電性絕緣材料可以 層的形式完全地覆蓋開口之側面。電性絕緣材料可以例如 介於至少30//m且至多100//m的厚度鋪設。 發光二極體可包含複數個開口於載體中,例如二或多 個開口。每一開口係以所述方式組構而成,且用以容納用 以安裝發光二極體於欲使用位置的固定裝置。 根據至少一實施例,開口完全地通過金屬基本體。也 5 95252 201205771 就疋忒,至少一開口係形成於金屬基本體區域的載體中 至少於金屬基本體區域中,開口的内表面接著較佳地以。 性絕緣材料完全覆蓋。換句話說,金屬基本體在開口 何一點並未被暴露出來,並可因此在發光二極體之操壬 間以簡化方式維持無電位的狀態。 ^ 根據發光二極體的至少一實施例,载體的安農面係μ 置於載體上側,且發光二極體晶片係直接於安褒面固二至 載體。例如’發光二極體晶片在此例子中係於安裳面_ i 接至載體。換句話說,除了例如銲料的連接裝置以外,^ 光二極體晶片係直接鋪設於載體的金屬基本體,並直接^ 其接觸。接著,電性絕緣層係在載體下側固定至載體,亦 即’在載體中面向遠離安裝面的一侧上。電性絕緣層較佳 地直接與金屬基本體接觸。電性絕緣層較佳地係於載體τ 側完全覆蓋,除了開口以外。換句話說,金屬基本體接著 亦藉由電性絕緣層完全地覆蓋於金屬基本體中面向遠離安 裝面的一側上。 電性絕緣層在此例子中具有至少2 W /( m k )的熱傳導性。 換句話說,在此具體實施例中’發光二極體晶片係直 接安裝於金屬基本體上’其能使發光二極體晶片與载體具 有最佳的熱耦合。載體的整個金屬基本體作為散熱元件。 在此例子中,發光二極體晶片可電性導電連接至金屬基本 體,且經由金屬基本體以並聯的方式彼此連接。金屬基本 體的電性絕緣係以電性絕緣層形成於面向遠離安裝面的一 侧上,其特徵係在於特別高的熱傳導性。此種設計的發光 95252 6 201205771 二極體能使發熱源(亦即,發光二極體晶片)提早直接散 熱,以及因此讓整個發光二極體有特別低的熱阻抗。 根據發光二極體之至少一實施例,電性絕緣層係為陶 曼層。這表示電性絕緣層具有陶究特性。電性絕緣層可包 括陶莞材料或由陶莞材料組成。電性絕緣層在此例子中具 有至少2W/(mk)的熱傳導性。 根據發光二極體之至少一實施例,電性絕緣層具有至 少3 0 // m且至多10 0 /z m的厚度。例如,電性絕緣層具有介 於至少50#111且至多70#111之間的厚度。 根據發光二極體之至少一實施例,電性絕緣層含有氮 化硼或由氮化硼所組成。在此例子中,電性絕緣層可具有 至少30/zm且至多ΙΟΟ/zm、例如介於至少50/zm且至多 70//Π1之間的厚度。電性絕緣層在此例子中具有至少2W/ (mk)的熱傳導性。 根據發光二極體之至少一實施例,發光二極體晶片係 電性導電連接至金屬基本體,且經由金屬基本體以並聯的 方式彼此連接。也就是說,發光二極體晶片係具有相同於 發光二極體晶片中面向金屬基本體的一侧上的金屬基本體 的電位。 根據發光二極體之至少一實施例,開口完全通過載體 下側上的電性絕緣層。換句話說,電性絕緣層亦被開口中 斷。在此例子中,開口可於電性絕緣層鋪設於金屬基本體 之前或之後產生。開口中電性絕緣層的側面較佳地係被電 性絕緣材料覆蓋,且内表面亦於金屬基本體之區域中以電 7 95252 201205771 性絕緣材料覆蓋。例如,為此目的,一旦電性絕緣層被鋪 設於載體下側時,開口之内表面係僅以電性絕緣材料塗 佈。在此例子中,亦有可能讓載體下側上之電性絕緣層以 相同材料(亦即電性絕緣材料)形成。 根據發光二極體之至少一實施例,供發光二極體晶片 固定的中間載體係設置於發光二極體晶片與安裝面之間。 中間載體可包含陶瓷材料或由陶瓷材料組成。換句話說, 中間載體表示發光二極體晶片與載體的電性絕緣,特別是 與金屬基本體的電性絕緣。在此例子中,亦能免除載體下 側的電性絕緣層。 根據發光二極體之至少一實施例,載體包含另一電性 絕緣層,其係固定至金屬基本體中面向發光二極體晶片的 一側上。供發光二極體晶片電性導電連接的電性導電層係 接著設置於該另一電性絕緣層中面向遠離金屬基本體的一 側上。電性導電層可於此例子中建構以形成導體執跡,其 產生發光二極體之發光二極體晶片之間的接觸。 根據發光二極體之至少一實施例,開口完全地通過另 一電性絕緣層以及電性導電層。在此例子中,開口中之另 一電性絕緣層以及電性導電層的側面係被電性絕緣材料覆 蓋。換句話說,在此具體實施例中,較佳地,開口之整個 内表面係被電性絕緣材料覆蓋。除了金屬基本體之外,另 一電性絕緣層以及電性導電層亦被電性絕緣材料覆蓋,且 因而與開口中的固定裝置電性絕緣。 根據發光二極體之至少一實施例,發光二極體的至少 8 95252 201205771 二個發光二極體晶片係埋入於反射塗層中。較佳地,發光 二極體的所有發光二極體晶片係埋入於反射塗層中。 「埋入」的意思於此處表示反射塗層覆蓋發光二極體 晶片的至少一些點,且與發光二極體晶片於覆蓋位置直接 接觸。例如,能夠讓反射塗層與發光二極體晶片中面向遠 離載體的輻射離開表面齊平。橫向於安裝面之發光二極體 晶片的那些側面接著完全地被例如反射塗層覆蓋。 此外,能讓反射塗層覆蓋發光二極體晶片中面向遠離 安裝面的的輻射離開表面。然後,反射塗層於該處具有微 小厚度,使得發光二極體晶片在操作期間產生的光可穿過 反射塗層通至外部。於發光二極體晶片的輻射離開表面 上,反射塗層接著作為擴散層,其擴散通過擴散層的光線。 除了發光二極體晶片以外,反射塗層較佳地亦覆蓋至 少部分安裝面。例如,安裝面係被反射塗層材料完全地覆 蓋於完全暴露的點,亦即,特別是無發光二極體晶片之處。
