Ma LED a Buluu SMD LED yokhala ndi SMT 3535 LED

3W Mkulu Mphamvu SMT 3535 LED ndi 480mn anatsogolera

3535PBC48D60L45 ndi LED yamphamvu yayikulu yokhala ndi 3535 SMD LED kesi. Chifukwa chakuti pali mandala olamulira pamwamba pa SMD LED, mutha kuyitananso kuti Dome Lens Lens SMD LED yamphamvu kwambiri. Nthawi zambiri buluu la SMD la buluu (kapena maenje obowola) amatulutsa 470nm LED kapena 450nm mtundu wabuluu wachifumu. 480nm idzayandikira kwambiri 520nm mtundu wobiriwira, kuti mtundu wa 480nm ukhale wowala wamadzi buluu. Ndi yopepuka kuposa 470nm kapena 460nm yakuya buluu LED. Yerekezerani ndi ma LED ena a buluu, mawonekedwe ofiira a buluu awa a 480nm ndiopadera komanso osavuta kuwona. Mukupanga uku, timayika ndi 3535 Blue SMD LED kesi ndikupanga ndi chip yamagetsi yayikulu. Mutha kuyendetsa mosavuta kuwunikaku ngakhale mutagwira ntchito zazing'ono. Nthawi yomweyo, mukafuna kuwala kapena kutulutsa kwina, ingomasuka kuwonjezera pano, imatha kugwira 700mA pakadali pano ndikupereka 50-70lm nthawi imeneyo.

Mukadakhala kuti mukufunafuna magetsi amphamvu okhala ndi mtundu wabuluu, iyi sikungakuletseni ~

Kukula kwa 3535 Blue SMD LED:

Magawo Amagetsi:

* Chitani msonkhano wapano: Ntchito 1% ndi Pulse width = 10us.

* Msonkhano wa Soldering: Msonkhano wa Soldering uyenera kumalizidwa ndi 3 secongds pa 260 ℃

* Mphamvu yowala imayesedwa ndi ZWL600.

* λD imachokera ku chithunzi cha CIE chromaticity ndipo imayimira kutalika kwake komwe kumatanthauzira mtundu wa chipangizocho.

Pofuna kuwonetsetsa kuti makasitomala athu onse atha kugwira bwino ntchito kuchokera ku 480nm LED yokhala ndi mphamvu yayikulu 3535, timatulutsa mphamvu yayikuluyi ya LED yokhala ndi chip chatsopano chokhazikika, chimango cha caremic LED, epoxy yapamwamba kwambiri yamagalasi ndi waya wagolide wangwiro kulumikizana kwamkati.

ZOSUNGIRA PA NKHANI

Yerekezerani ndi epoxy encapsulant yolimba komanso yopepuka, silicone ndiyofewa komanso yosinthasintha Althouth mawonekedwe ake amachepetsa kwambiri kupsinjika kwamafuta, kumatha kuwonongeka ndimphamvu yamagetsi. Zotsatira zake, kusamala mosamala kuyenera kuwonedwa pamsonkhano pogwiritsa ntchito zinthu za Silicone zomwe zidakulungidwa. Kulephera kutsatira izi kumatha kubweretsa kuwonongeka komanso kulephera kwazomwe akutsogolera

1. Gwiritsani chinthucho m'mbali mwa mbali pogwiritsa ntchito zida zamphamvu kapena zida zoyenera.

2, Musakhudze mwachindunji kapena kusamalira mandala a silicone. Zingawononge mayendedwe amkati.

3, Osati okwana pamodzi PCBS anasonkhana munali LEDs poyera. Zovuta zimatha kukanda mandala a silicone kapena kuwononga mayendedwe amkati.

4, 4-A Mkati wamkati mwa kamphindi kakang'ono ka SMD sayenera kupitirira kukula kwa LED popewa kutuluka kwa mpweya;

Zolemba 4-BA zimalangizidwa kuti nsonga ya nozzle ipewe kugwirana kapena kuwononga mawonekedwe a LED panthawi yonyamula.

4-C The gawo la chigawocho liyenera kukonzedwa molondola mu makina osankhika ndi malo kuti atsimikizire kunyamula bwino ndikupewa kuwonongeka pakupanga;

4-D Monga silicone encapsulation imatha kupezeka m'mipweya, zinthu zina zowononga monga H2S zitha kuwononga siliva plationg wa leadframe. Chisamaliro chapadera chiyenera kutengedwa ngati LED yokhala ndi silicone encapsulation iyenera kugwiritsidwa ntchito pafupi ndi zinthu ngati izi.

5, Chonde aviod mupitilize kuwonetsetsa malo omwe amadzetsa chinyezi ndikusunga malonda ake kuti asadzabwerenso kusintha kwa kutentha kozungulira.

6, Zogulitsa zomwe zidasindikizidwa koyambirira zimalimbikitsidwa kuti zisonkhanitsidwe pasanathe maola 24 kutsegulidwa.
