Super Bright 3mm Blue LED Yosakanizidwa ndi Lens

3mm Buluu Wobowola Buluu wokhala ndi mandala obiriwira a 40 degree:

Izi 304BD46D2L12 ndi LED yabuluu yomwe imakhala ndi mandala obiriwira. Monga tikuwonera pachithunzichi, utoto wamagalasi ukuwoneka ngati madzi owala amtambo osati akuda kwambiri. Zachidziwikire, ngati mungafune mandala akuda obiriwira a 460nm - 470nm LED ingomasuka kutidziwitsa ~ Titha kukupangiraninso. Kumbali inayi, pakupanga, timatulutsanso buluu kudzera mu dzenje lowonera mozungulira la 40 degree, lomwe lingatsimikizire kuti limatha kuyatsa malo ambiri. Pazoyang'ana, 20 degree 30 degree, 40 degree, 60 degree kapena 90 dgree zonse zilipo. Mawonekedwe owonera osiyanasiyana amatulutsa malo owala pang'ono, pang'ono pang'ono, malo owala pang'ono komanso mtunda wautali woyatsa. Ngati mukufuna zina mwa buluu wa LED pantchito yanu yowunikira, ingolumikizanani nafe kuti mumve zambiri za ~

3mm Blue LED yokhala ndi mandala obalalika Kukula:

Zojambula Zobiriwira Zobiriwira Kudzera:

* Kukula kwa Lens: 3mm;

* Timaganiza 460-465nm;

* Mtundu wa mandala: Buluu wamwazikana;

* Kudalirika kwakukulu komanso kutentha kwa radiation;

Magawo Amagetsi:

* Chitani momwe zinthu ziliri pano: Udindo 1% ndi kugunda m'lifupi = 10us.

* Mkhalidwe wa Soldering: Soldering condition iyenera kumalizidwa ndi 3 secongds pa 260 ℃

Makhalidwe a Electrucal Optical (Tc = 25 ℃ )

* Mphamvu yowala imayesedwa ndi ZWL600.

* /1 / 2 ndi yopanda-sxis angle pomwe mphamvu yowala ndi theka la mphamvu ya axia yowala;

Zakuthupi za buluu kudzera mu dzenje la LED:

Ntchito:

LED Kukongola chigoba;

Anatsogolera Back Kuwala;

Kupanga patsogolo pakuyenda kwa dzenje la LED:

Fananizani ndi SMD LED, kupanga kwa maenje a LED kudzakhala kovuta kwambiri. Zomwe zikutanthauza kuti zitenga nthawi yambiri yopanga komanso nthawi yopanga:

Choyamba, tiyenera kukonzekera chip cha LED (izi zidzakhala zofanana ndi kupanga kwa SMD LED ); Kachiwiri, tifunikira kuyika chip cha LED mu chimango cha LED, kenako tidzafunika waya wagolide woyenera kulumikiza cathode ndi anode ya chimango cha LED. Zimabwera mosiyana, Kupanga kwa SMD kwa LED, tifunika kuyika epoxy ku chimango cha LED ndikudikirira mpaka chouma ndi uvuni. Komabe, pamagetsi a LED, tifunika kubaya epoxy mu nkhungu ya mandala ndikuyika zinthu zonse mu uvuni kwa maola osachepera 8 mpaka zitayanika. Pambuyo pake, tifunika kuwayanjanitsa ndi uvuni ndikuchotsa ma LED pachikombole. Ndipo tifunika kudula zikhomo za LED kuti zikhale zosavuta kuyesa.

Pomaliza, tili ndi LED. Pofuna kuonetsetsa kuti mtunduwo ndi yunifolomu ndizofunikira momwe zingafunikire. Tiyeneranso kuyika ma LED onse pamakina olekanitsa ndipo tidzapeza ma LED okhala ndi nkhokwe zomwezo.

Zinthu Zosungirako:

1. pewani kupitilizabe kutentha kwa chinyezi ndikusunga mankhwalawo kuti asasinthidwe kwambiri kutentha kozungulira;

2. Ma LED amayenera kusungidwa ndi kutentha ≤30 ℃ ndi chinyezi chochepa <60% ℃;

3. Zogulitsa zomwe zili phukusi loyikidwiratu zikulimbikitsidwa kuti zisonkhanitsidwe pasanathe maola 72 kutsegulidwa;

4. Zogulitsa zomwe zatsegulidwa kwa nthawi yopitilira sabata ziyenera kuphikidwa kwa maola 6-8 pa 85-10 ℃;

NJIRA YOPHUNZITSIRA YA LED

1, Kutsogolera kutsogolera kwa LED kuyenera kufanana ndi mabowo okwera pa PCB pakapangidwe kazinthu;

Kupanga kutsogolera kungafunike kutsimikizira kuti phula lotsogolera likufanana ndi phula;

Tchulani chithunzi chili pansipa kuti mupeze njira zoyenera zopangira;

Osayendetsa njira ya PCB pamalo olumikizirana pakati pa leadframe ndi PCB kuti mupewe ma circuits amafupika;

Odziwa:

Njira Yokhazikitsidwa yolondola;

× Njira yolakwika yolowera;

2. Mukamasungunula mawaya ku LED, cholumikizira chilichonse cha waya chiyenera kutetezedwa ndi chubu chochepetsera kutentha kuti muchepetse kulumikizana kwakanthawi.

Musagwirizane ndi zingwe zonse mu chubu chimodzi chotenthetsera kutentha kuti mupewe kutsina kutsogolera kwa LED;

Kutsina kutsogolera pazitsogozo zotsogozedwa kumatha kuwononga mawonekedwe amkati ndikupangitsa kulephera;

Odziwa:

Njira Yokhazikitsidwa yolondola;

× Njira yolakwika yolowera;

3. Gwiritsani ntchito zoyimilira (mkuyu 3) kapena spacers (mkuyu 4) kuti muike bwino LED pamwamba pa PCB;

4. Sungani malo osachepera 3mm pakati pamunsi mwa mandala a LED ndi kokhotakhota koyamba (mkuyu. 5. mkuyu. 6)

5. Pakapangidwe ka lead, gwiritsani ntchito zida kapena ma jig kuti mugwire zotsogola mosamala kuti mphamvu yopindayo isafalitsidwe ku mandala a LED ndi zomangidwe zake zamkati;

Osachita kutsogolera kupanga kamodzi chigawo wakhala atakwera pa PCB ndi;

L ead Ndimapanga Opaleshoni

1. Njira Zotsogolera Kupanga;

2. Osakhotetsa zikopa kuposa kawiri (mkuyu 7);

3. Pakati pa soldering, zophimba ndi zopalira ziyenera kusiya chilolezo kuti zisawonongeke kuwonongeka kwa LED panthawi ya soldering (mkuyu 8);

4. Nsonga yachitsulo chosungunula sayenera kukhudza epoxy ya mandala;

5. Ma LED opyola mu dzenje samagwirizana ndi kuwotcherera kosungunuka;

6. Ngati LED idzadutsa ma soldering angapo kapena ingakumane ndi njira zina komwe gawolo lingatenthedwe kwambiri chonde onani ndi Best LED kuti igwirizane;
