Description

LED燈條之製造方法及其結構
本發明與LED燈條有關,特別是有關於一種LED燈條之製造方法及其結構。
請參閱第一圖所示之習用LED燈條10,其主要是利用表面黏著技術(Surface Mounted Technology,SMT)將複數個LED封裝件12設置於軟性電路板14的表面,接著再將軟性電路板14連同LED封裝件12進行回焊製程,讓LED封裝件12能夠確實地焊接固定於軟性電路板14的表面,以完成LED燈條10的製作,但是回焊製程的高溫很容易對LED封裝件12造成不良影響。
請再參閱第二圖所示之另一種習用LED燈條20,其主要是先將複數個LED晶片22經由膠帶24固定於承座26的表面之後,再進行各LED晶片22的封裝以完成LED燈條20的製作。然而,此習用LED燈條20是將多個承座26採用焊接的方式連接成所需要的長度,如此將會造成製造成本及製造工時的增加。
本發明之主要目的在於提供一種LED燈條之製造方法,其不需要經過回焊製程,並且能降低製造成本且節省製造工時。
為達成上述目的,本發明之製造方法先提供一捲帶式導線架,接著將一膠帶開設出複數個呈間隔排列之開孔,再將該膠帶貼附於該捲帶式導線架之頂面,接著根據各該開孔的位置將複數個LED晶片黏合於該捲帶式導線架之頂面,並對各該LED晶片進行封裝製程以形成一LED封裝件,最後再對該捲帶式導線架進行裁切,藉以完成該LED燈條的製作。
由上述可知,本發明之製造方法採用該捲帶式導線架進行該LED燈條的製作,並不需要經過回焊製程,以避免回焊製程的高溫對各該LED封裝件造成影響,同時只要依據所需長度進行裁切,可免除採用多段焊接製程。
本發明之次一目的在於提供一種依前述製造方法所製造而成的LED燈條,其製造方便且具有低廉的製造成本。
為達成上述目的,本發明之LED燈條包含有一承座、一膠帶,以及複數LED封裝件,其中該承座是由前述捲帶式導線架裁切而成,該膠帶貼附於該承座之頂面,並具有複數個呈間隔排列之開孔,各該LED封裝件經由該膠帶之各該開孔而設於該承座之頂面。
為了詳細說明本發明之步驟、特徵及功效所在,茲舉以下較佳實施例並配合圖式說明如後。
本發明一較佳實施例所提供之LED燈條30之製造方法,包含有下列步驟:
步驟a):提供一捲帶式導線架32,係定義出複數個相連之承載區34及複數個相連之裁切區36,如第三圖A所示,相鄰之二承載區34之間具有一裁切線L,如第四圖所示,裁切區36兩兩成對地連接於承載區34的兩側。
步驟b):先將一上膠帶40開設出複數個呈間隔排列之開孔42,用以標示出LED晶片46所要黏合的位置及正負電極連接的位置,之後再將上膠帶40貼附於捲帶式導線架32之承載區34的頂面,如第三圖B所示,接著貼附一下膠帶44於捲帶式導線架32之承載區34的底面,如第三圖C所示。
步驟c):根據各開孔42的位置將複數個LED晶片46黏合於捲帶式導線架32之承載區34的頂面,下膠帶44可防止LED晶片46黏合時所灌注之膠材滲漏,接著對各LED晶片46進行封裝製程,用以形成一LED封裝件48,如第三圖D所示。
步驟d):先將捲帶式導線架32之裁切區36裁斷,使承載區34形成一承座,接著再依據所需要的長度沿著裁切線38進行裁切作業,如此便完成LED燈條10的製作,如第三圖E所示。
經由上述步驟可知,本發明之製造方法採用捲帶式導線架32進行LED燈條10的製作,可省略回焊製程,以避免回焊製程的高溫對各LED封裝件48造成影響,同時只要依據所需長度進行裁切,可免除多段焊接製程,以達到降低製造成本與節省製造工時的目的。另一方面,本發明之製造方法所製造而成之LED燈條10係具有承座(亦即承載區34)、貼附於承座頂面之上膠帶40、貼附於承座底面之下膠帶44,以及設於承座頂面且位於上膠帶40之開孔42內之LED封裝件48,如第三圖E所示,在後續的組裝作業時先貼附一絕緣導熱膠帶50於一散熱座52上,接著再將LED燈條10貼附於絕緣導熱膠帶50上,如第五圖所事,最後再進行正負電極的連接即完成組裝。
本發明於前揭實施例中所揭露的構成元件,僅為舉例說明,並非用來限制本案之範圍,其他等效元件的替代或變化,亦應為本案之申請專利範圍所涵蓋。
