Super Bright 3mm Kupyola-bowo la LED Red Red Lophatikizidwa

Super Bright 3mm yofiira yokhala ndi mandala a LED

Izi 3mm LED 304FRD-8 ndiye owala kwambiri 3mm ofiira ofiira mu fatory yathu. Omwe ali ofala kwambiri komanso ofiira ofiira okhala ndi mandala ofiira ofunikira ndipo adavotera kutsogolo kwa 20mA. Ngati ma 3mm ena ofiira ofiira a LED sali owala mokwanira kuti mugwiritse ntchito. Chonde funsani ndi iyi.

Fananizani ndi 3mm 625nm LED ina, iyi 304FRD- imatha kufikira kuwala pa 700-1000mcd mukayatsa pa 20mA. Chifukwa cha kuwala kowala kwambiri, nyali za LEDzi ndizabwino pulojekiti yowunikira kumbuyo kwa LED, projekiti ya LED ndikuwonetsa kuyatsa kwa LED. Nthawi yomweyo, LED yaying'ono ya Red Throguh-hole ndiyabwino kuchitira DIY. Kuti muyatse LED iyi ya 3mm Red Through-hole, mumangofunika chisonyezo champhamvu, masensa a opto-electronic.

Kodi mukufunikira kuwala kofiira kwambiri mu 3mm m'mimba mwake? Lumikizanani nafe kuti mumve zambiri za ~

Kukula kwa 3mm Red LED:

Kupyola mu dzenje Zochitika za LED:

* Kukula kwa Lens: 3mm;

* Wavelength 620-630nm;

* Mtundu wa mandala: Kufiyira kofiira;

* Kudalirika kwakukulu komanso kutentha kwa radiation;

Magawo Amagetsi:

* Chitani momwe zinthu ziliri pakali pano: Udindo 1% ndi pulse width = 10us.

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

Makhalidwe a Electrucal Optical (Tc = 25 ℃ )

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

Ntchito yayikulu:

* Abwino backlight;

* Chizindikiro cha kuwala;

* LED kukongoletsa nyale;

Zambiri Zamalonda:

99,99% yoyera waya wagolide;

Siliva yokutidwa ndi chimango cha LED;

Tchipisi todziwika bwino;

Mkulu khalidwe epoxy;

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 ); Chachiwiri, 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 muchikombole cha mandala ndikuyika zinthu zonse mu uvuni kwa maola osachepera 8 mpaka zitayanika. Pambuyo pake, tifunika kuwayanjanitsa ndi uvuni ndikupeza ma LED kuchokera ku nkhungu. 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 mwachangu;

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, Kutayira kwa LED kuyenera kufanana ndi mabowo omwe akukwera pa PCB panthawi yopangira zinthu ;

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. Mukamagwiritsa ntchito zingwe ku LED, cholumikizira chilichonse cha waya chiyenera kutetezedwa ndi chubu chochepetsera kutentha kuti muchepetse kulumikizana kwakanthawi.

Osamangirira mawaya onse awiri mu chubu chimodzi chotenthetsera kutentha kuti mupewe kutsina kutsogolo 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 ndalama zosachepera 3mm cl pakati pa 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 zipangidwe zake zamkati ;

Osachita kutsogolera kupanga kamodzi chigawo wakhala atakwera pa PCB ndi ;

L ead Ndimapanga Opaleshoni

1. Njira Zopangira ;

2 . Osakhotetsa zotsogola kuposa kawiri (mkuyu 7 );

3. Panthawi ya soldering, zikuto zamagulu ndi zopalira ziyenera kusiya chilolezo kuti zisawonongeke kuwonongeka kwa LED panthawi ya soldering (mkuyu 8) ;

4. Nsonga yachitsulo chosungunulira sayenera kukhudza epoxy ;

5. Mwa-dzenje anatsogolera m ali osayenerana ndi soldering reflow;

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