Inkomoko yumucyo LED
GakondoItaraInkomoko ifata uburyo bumwe bwo gupakira ibintu, bigizwe na LED chip, insinga za zahabu, utwugarizo, ifu ya fluorescent, hamwe na colloids. Chip yashizwe hepfo yumukono wigikombe cyerekana hamwe nudukingirizo, kandi insinga ya zahabu ihuza chip electrode na chip uyifata. Ifu ya fluorescent ivanze na silicone kugirango itwikire hejuru ya chip kugirango ihindurwe.
Ubu buryo bwo gupakira bwaremye uburyo butandukanye nko kwinjiza mu buryo butaziguye no kuzamuka hejuru, ariko mubyukuri ni inshuro nyinshi ihuza ibice byigenga bitanga urumuri, nkamasaro yatatanye bigomba guhuzwa neza murukurikirane kugirango bimurikire. Nyamara, iyo wubatse isoko nini yumucyo, ubunini bwa sisitemu ya optique bwiyongera cyane, kimwe no kubaka inyubako nziza isaba imbaraga nimbaraga nyinshi zo guteranya no guhuza buri matafari namabuye.
COB isoko yumucyo
COB itaraInkomoko zinyura muri paradigima gakondo kandi ikoresha tekinoroji ya chip itaziguye kugirango ihuze mu buryo butaziguye kugeza ku bihumbi ibihumbi bya LED ku cyuma gishingiye ku cyuma cyanditseho imbaho cyangwa icyuma cyitwa ceramic. thermodynamics.
Kurugero, Lumileds LUXION COB ikoresha tekinoroji yo kugurisha eutectic kugirango ihuze chipi 121 0.5W kuri substrate izenguruka ifite diameter ya 19mm, hamwe na 60W yose. Umwanya wa chip uhagarikwa kuri 0.3mm, kandi hifashishijwe ubufasha bwihariye bwerekana, uburinganire bwo gukwirakwiza urumuri burenga 90%. Ipaki ihuriweho ntabwo yorohereza gusa umusaruro, ahubwo inashiraho uburyo bushya bw "isoko yumucyo nka module", itanga umusingi wimpinduramatwara kurikumurikaigishushanyo, kimwe no gutanga ibyakozwe mbere yuburyo bwiza kubashushanya amatara, kuzamura cyane imikorere yubushakashatsi nibikorwa.

Ibikoresho byiza:Guhinduka kuvaurumuriInkomoko Kuri Ubuso Umucyo
LED imwe
LED imwe ni isoko yumucyo wa Lambertian, itanga urumuri kumpande zingana na 120 °, ariko gukwirakwiza ubukana bwurumuri byerekana kugabanuka gukabije kwamababa yababa hagati, nkinyenyeri yaka cyane, ikayangana cyane ariko ikanyanyagiza kandi idafite gahunda. Guhura nakumurikaibisabwa, birakenewe kuvugurura urumuri rwo gukwirakwiza umurongo binyuze muburyo bwa optique.
Gukoresha lens ya TIR muri sisitemu ya lens irashobora guhagarika inguni ziva kuri 30 °, ariko igihombo cyumucyo gishobora kugera kuri 15% -20%; Imashini ya parabolike muri gahunda yo kumurika irashobora kongera urumuri rwagati, ariko bizatanga urumuri rugaragara; Iyo uhuza LED nyinshi, birakenewe gukomeza umwanya uhagije kugirango wirinde itandukaniro ryamabara, rishobora kongera ubunini bwitara. Ninkaho kugerageza guhuriza hamwe ishusho nziza hamwe ninyenyeri mwijuru ryijoro, ariko burigihe biragoye kwirinda inenge nigicucu.
Ubwubatsi Bwuzuye COB
Imyubakire ihuriweho na COB mubisanzwe ifite ibiranga ubusourumuriInkomoko, nka galaxy nziza cyane ifite urumuri rworoshye kandi rworoshye.Multi chip dense gahunda ikuraho ahantu hijimye, ihujwe na tekinoroji ya micro lens array, irashobora kugera kumurika> 85% mumwanya wa 5m; Mugukata hejuru yubutaka, impande zangiza zishobora kwaguka kugera kuri 180 °, bikagabanya indangagaciro (UGR) kugeza munsi ya 19; Munsi yumucyo umwe, kwaguka kwa optique ya COB kugabanukaho 40% ugereranije na LED array, byoroshya cyane igishushanyo mbonera cyo gukwirakwiza urumuri.Mu nzu ndangamuragekumurikaibiboneka, inzira ya COB ya ERCOamatarakugera ku kigereranyo cya 50: 1 kumurika kuri metero 0,5 unyuze mumurongo wubusa, gukemura neza kwivuguruza hagati yo kumurika kimwe no kwerekana ingingo zingenzi.

Igisubizo cyo gucunga ubushyuhe:guhanga udushya kuva ubushyuhe bwaho kugeza kuri sisitemu urwego rwo gutwara ubushyuhe
Inkomoko yumucyo LED
LEDs gakondo ifata inzira enye zo gutwarwa nubushyuhe bwa "chip solid layer support PCB", hamwe nibintu bigoye byo kurwanya ubushyuhe, nkinzira ihindagurika, ibuza ikwirakwizwa ryihuse ryubushyuhe. Kubijyanye na interineti irwanya ubushyuhe, hariho guhuza ubushyuhe bwa 0.5-1.0 ℃ / W hagati ya chip na bracket; Kubijyanye no kurwanya ubushyuhe bwumuriro, ubushyuhe bwumuriro bwubuyobozi bwa FR-4 ni 0.3W / m · K gusa, bihinduka icyuho cyo gukwirakwiza ubushyuhe; Mugihe cyo guteranya ibintu, ahantu hashyushye hashobora kongera ubushyuhe bwihuza 20-30 ℃ mugihe LED nyinshi zahujwe.
Ubushakashatsi bwakozwe bwerekana ko iyo ubushyuhe bwibidukikije bugeze kuri 50 ℃, igipimo cyangirika cyumucyo wa SMD LED cyihuta inshuro eshatu ugereranije n’ibidukikije 25 and, kandi igihe cyo kubaho kigabanuka kugera kuri 60% bya L70. Nkigihe kirekire guhura nizuba ryinshi, imikorere nubuzima bwaItaraInkomoko izagabanuka cyane.
COB isoko yumucyo
COB ifata ibyiciro bitatu byububiko bwa "chip substrate heat sink", igera ku ntera mu micungire y’ubushyuhe, nko gushyira umuhanda mugari kandi uringaniye kuriurumuriamasoko, yemerera ubushyuhe gukorwa vuba no gutatana. Kubijyanye no guhanga udushya, insimburangingo yubushyuhe ya aluminium substrate igera kuri 2.0W / m · K, naho iyitwa aluminium nitride ceramic substrate igera kuri 180W / m · K; Kubijyanye nubushyuhe bumwe, ubushyuhe bumwe bushyirwa munsi ya chip array kugirango igenzure itandukaniro ryubushyuhe muri ± 2 ℃; Irashobora kandi guhuza no gukonjesha amazi, hamwe nubushobozi bwo gukwirakwiza ubushyuhe bugera kuri 100W / cm ² iyo substrate ihuye nisahani ikonjesha.
Mugukoresha amatara yimodoka, urumuri rwa Osram COB rukoresha igishushanyo mbonera cyo gutandukanya ubushyuhe bwa termoelektrike kugirango ihagarike ubushyuhe bwihuza munsi ya 85 ℃, bujuje ibyangombwa bisabwa byizewe byimodoka za AEC-Q102, ubuzima bwamasaha arenga 50000. Nkaho gutwara umuvuduko mwinshi, irashobora gutanga ituze kandiitara ryizewekubashoferi, kurinda umutekano wo gutwara.
