Buluu ya Mini Mini Yoyatsira 4.5V Yoyatsa

8mm Blue Mini LED yokhala ndi 4.5V kuphethira:

806UBD-E10IC iyi ndi nyali zowala za LED mukamapereka zaposachedwa. Pofuna kuti LED iyi ikhale ndi kuwala kothwanima, timangowonjezera IC mkati mukamapanga. Malingana ngati mutalumikiza babu yaying'ono ya LED mkati mwazunguliralo, zomangira mu IC zitha kugwira ntchito ndikupangitsa kuti kuwala kuphenye. Muli babu yaying'ono pamsika koma ambiri aiwo amapangidwa ndimatumba agalasi, omwe atha kukhala owopsa mukamagwiritsa ntchito. Poterepa, timagwiritsa ntchito buluu yathu ya 8mm yabuluu kudzera mu dzenje kuti tipeze babu ya E10 mini LED. Kuchokera pazinthuzo, pali mandala a epoxy panja kuti asinthe babu. Ndiotetezeka osati eady kuthyola mukamagwiritsa ntchito. Zomwe ndizotetezeka kwambiri komanso zabwino pulojekiti ina ya DIY.

8mm mini anatsogolera babu Kukula:

Ma BlueThrough-hole LED Zinthu:

* Kukula kwa Lens: 8mm;

* Timaganiza 460-470nm;

* Mtundu wa mandala: Buluu wakuya wasokonekera;

* Kudalirika kwakukulu komanso kutentha kwa radiation;

Magawo Amagetsi:

* Chitani momwe zinthu ziliri pakali pano: Udindo 1% ndi kupopera 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:

Ntchito ya LED DIY;

Ntchito yowunikira ya LED;

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); 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 mu nkhungu ya 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. Kuti muwonetsetse kuti mtundu 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;
