200936937 六、發明說明: 【發明所屬之技術領域】 本案係關於節曰裝飾用之燈串。 【先前技術】
典型燈串由複數燈泡組成,以串聯或並聯之電氣方式接 線在一起。燈串一端有電氣插頭,適於插入牆壁插座或其中 電源’另一端插座適於容納第二燈串之插頭,以便輸送電至 ,二燈串。大多數燈串以家用交流電操作。近來,有些燈串 是以置於插頭或插座内之整流器產生之直流電操作,例如本 申請人在美國專利第5,777,868 ; 5,994,845和6,869,313號所 揭示,於此列入參考。此等燈串用電少,在較低溫’操作(故 較依賴交流電的習用燈串經濟,且失火情形少。位於插頭内 的整流器優點是,只需二金屬線,即可帶電至燈串之燈泡。 惟此種直流燈串會輸送直流電至燈串另一端之插座,故次一 燈串必須也以直流電操作。 把整流器置入插座内的優點是,插座可輸送交流電至次 一燈串,並輸送直流電至第一串之電燈。可惜此項配置需額 外金屬線。 每年生產燈串有數億組之多,涉及成本為燈串廠家的重 大焦點’尤其是在材料成本上漲時。即使單_燈串的遞增材 料戈勞力成本很少,但維持成本低,或藉減少材料和 量,積少成多,便相當可觀。 另外,燈串之燈由白熾燈泡,改用發光二極體(LED 者乂來愈多。LED用電比傳統白雕更少,發生的熱更微。 LED不像白舰泡’是單向通電流,故僅限於細直流電。 因此,仍需製造安全、用電少,又能產生所需裝飾效 果’且維持生產成本低之燈串。 【發明内容】 按照簡述之主要層面’本發明係一種LED燈串,以直流 200936937 電供電,燈串同時又把錢電通職座。本發串採用全 波整流電橋,產生供電LED所需之直流電,但電橋分成第一 部巧在燈串一端之插頭内,第二部份在另一端之插座内,整 流器有一個二極體在插頭内,另二個二極體在插座内。 分裂電橋式紐H之優點是’料電路把紐電輸送至 插座’直流電至負載’但比在插座内有整流器之LED燈串所 需導電金屬線少’因為輸送AC至插座所用金屬線,可 電橋之一部份。 ^
在另類較佳具體例中,本發明燈串之燈泡是LED,以成 串LED^組群形成串聯/並聯造型加以配置,各組群有三個 LED電氣並聯,而各組群以電氣串聯配置。 上述及其他特點和優點,凡精於電氣燈串技藝之專家, 詳閱以下參照附圖所述較佳具體例之詳細說明,即可 【實施方式】 本發明燈串可用於假日裝飾。本燈串最好使用發光二極 體(LED) ’而非白熾燈,在一組有二或以上LED並聯配置 (意即一或以上LEE彼此呈電氣以相同極性並聯配置)内, LED是串聯配置形成一組群,再將多組群彼此電氣串聯配 置。更好是,使用此串聯/並聯配置時,半導體裝置亦與各 組群,聯,在該組群内之LED燒毀或失落時,可調整電壓'。 茲參見第1圖,在燈串1〇 —端是插頭12,適於連接至 交流(AC)電源,諸如牆壁插座。在燈串1〇另一端是插座 14,於插頭12連接至輸送AC至插頭12之踏壁插座時,適 於輸送AC至次一燈串。插頭12和插座14之間連接複數 LED 16。熔線18可用於非極化插頭。 直流(DC)電利用二部份組成的電橋式整流器,輸送至 燈串10之LED 16。第一部份20接至燈串10的第一端,第 二部份22接至燈串10對立之第二端。最好是把第一部份加 入插頭12内’第二部份22加入插座14内。 整流器之第一和第二部份20,22,各有二個二極體。對全 4 200936937 而言,插頭12内之一個二極體30和插座14内之-個 H32」在第―半週期内通電流經led 16;而插頭12内 ^ 一固一極體34和插座14内之第二個二極體36,在第二 半=内通電流經LED 16。把AC從插頭12通至插座14^
二金屬線4〇,42 ’亦做為整流器之一部份’在各半週期 電路°因此’僅需三條金屬線:二AC金屬線40,42和 π,線44,從插頭12行經第一 LED 16,再第二LED m 1m第+二LED16,依此類推。直流熔線38最好位在燈串 後LED 16和電橋式整流器的第二部份22之間。 α 圖表示本發明變通之較佳具體例。第2圖所示燈串 士 於—端的插頭54和第二端的插座56之LED 52組 成。熔線58最好用於非極化插頭54。 όο/Λ式整流器從插頭54接受Ac,經第—端之二極體 ^2和第二端之二極體64 66,輸送DC至LED 52,而第一 ^和第二導體72輸送AC至插座56 ,把隨後燈串插入 Γϋ間内即可用。DC熔線最好插入於led 52和二極體 ❹ = 52分成LED 52之組群80,各組群80内之各led W Φ *組群内以彼此LED 52電極並聯配置。組群80彼此 電乳串聯配置。當然,需要附加接線9〇,並 8〇,但附加接線90增加額外燈。 同時ίΪ串rJ0,50 ’容許AC從插頭12,54輸送至插座14,56, it t 至㈣16,52,如此一來,輸送AC至插座 省輸d㈣ 而+i發明範®旨在包含加人其主要設計_之所有修改, ^本發明範圍和_,係輯辭請專利範其等效 ί他舰此所述構想可以互換,和/或:本發明 改和取代,不違本發明之精神或範圍。 ’他修 200936937 Ο 【圖式簡單說明】 第1圖為本發明較佳具體例燈串之示意圖 第2圖為本發明較佳具體例另類LED燈串圖。 【主要元件符號說明】 10,50 燈串 12,54 插頭 14,56 插座 16,52 發光二極體(LED) 18 熔線 20 第一部份 22 第二部份 30,60 插頭之第一 LED 32,62 插座之第一 LED 34,64 插頭之第二led 36,66 插座之第二LED 38,68 DC熔線 40,42,44 金屬線 70 第一導體 72 90 第二導體 附加接線 80 組群
