12V 3mm Wobiriwira Wobiriwira Wopangidwa ndi Resistor DC

12 Volt kutsogozedwa ndi 12V 3mm Kudzera-dzenje anatsogolera Green koonekera anatsogolera

Kumeneko njira ziwiri kutulutsa 12V kuwala emitting diode, woyamba ndi Pre-waya resistor mu kutsogolera LED. Kutanthauza, nthawi iliyonse tinamaliza yopanga anatsogolera Nyali, tiyenera china chotulutsa ndi resistor mini (za 1mm) kwa mwendo zinachititsa kuti akhoza onetsetsani Izi zinachititsa ntchito m'khola 12V mkulu voteji. Komano, ife tingakhoze kuwonjezera anamumanga resistor mu anatsogozedwa, amene ali pamodzi ndi Chip inatsogolera. Izi 304LGD52D7L12V12 nawo anamumanga resistor mkati wobiriwira koonekera phukusi, ngakhale izi 3mm wobiriwira kudzera-dzenje LED, ndi resisitor akadali aang'ono mokwanira kuti mmatumba mkati. Mwa njira imeneyi, tikhoza sangathe kuona resistor pang'ono becuase wa zinachititsa mandala. Koma kuchita ntchito zabwino Green Throguh-dzenje LED mkati. Ngati mukufuna ena 12V 3mm anatsogolera wobiriwira ntchito yanu, monga omasuka kulankhula ife ndi kupeza mwatsatanetsatane za izo ~

Gawo la 3mm Green kudzera-dzenje LED:

Zamagetsi:

* Pindani patsogolo pakali pano: Ntchito 1% ndi pulse wide = 10us.

* Mkhalidwe wowotchera: Kuwotchera kuyenera kumalizidwa ndi 3 secongds pa 260 ℃

Electrucal Kuwala Kaperekedwe (TC = 25 ℃)

*Luminous Intensity imayesedwa ndi ZWL600.

*θ1/2 ndi off-sxis angle pomwe kuwala kowala ndi theka la axia luminous intensity;

Main ntchito:

* Wagalimoto ka kuyatsa;

* Njovu kuwala;

* Enigine kuyatsa;

* Njinga yamoto ka kuyatsa;

Tsatanetsatane wa Zamalonda:

99.99% waya wagolide woyera;

Silver yokutidwa chimango LED;

Tchipisi zodziwika bwino;

Epoxy yapamwamba kwambiri;

Zotsimikizira patsogolo kudzera-dzenje anatsogolera:

Yerekezerani ndi SMD anatsogozedwa, kudzera-dzenje anatsogolera kupanga adzakhala zambiri zovuta. Kutanthauza kudzatenga kwambiri kupanga patsogolo ndi nthawi yopanga:

Choyamba, tiyenera kukonzekera Chip LED (uyu adzakhala yemweyo monga kupanga SMD anatsogolera); Kachiwiri, tiyenera kuika Chip anatsogolera mu chimango inatsogolera, kenako tiyenera golide woyenga waya kugwirizanitsa cathode ndi anode ya chimango LED. Apo pakubwera osiyana, kupanga SMD anatsogozedwa, tiyenera kuika epoxy kwa chimango kutsogozedwa ndi kudikira mpaka ziume ndi uvuni. Komabe, anatsogolera Nyali, tiyenera jekeseni epoxy mu nkhungu disolo ndi kuika zinthu zonse kuti uvuni kwa maola osachepera 8 mpaka iwo ziume. Pambuyo pake, tiyenera Aphunzitsi iwo kuchokera uvuni ndi kutenga LED kunja nkhungu. Ndiyeno tiyenera kudula zikhomo za zinachititsa kuti athe kukhala zosavuta mayeso.

Potsiriza, ife tiri inatsogolera. Pofuna kuonetsetsa khalidwe ndi yunifolomu wabwino monga chofunika. Tiyeneranso kuika onse zinachititsa kuti makina kulekana ndi iwo tidzakhala nawo LED ndi bins chomwecho.

Yosungirako zokwaniritsa:

1. Pewani anapitiriza kukhudzana kwa condensing chilengedwe chinyezi ndi kusunga mankhwala kuchokera kusintha mofulumira yozungulira kutentha;

2. LEDs ziyenera kusungidwa ndi kutentha ≤30 ℃ ndi chinyezi wachibale <60% ℃;

3. Mankhwala mu phukusi choyambirira losindikizidwa tikulimbikitsidwa kuti anasonkhana mwa maola 72 a kutsegula;

4. Mankhwala mu phukusi mpata kuposa sabata ayenera anaphika kwa maola 6-8 pa 85-10 ℃;

LED AKUWONONGA NJIRA

1, The Lea D phula la anatsogolera ayenera kufanana mamvekedwe a maenje ogwiritsa pa PCB pa Kusinthaku chigawo;

Tsogolerani-kupanga ukafunidwe kutsimikiza kutsogolera phula likufanana una phula;

Fotokozani chithunzi pansipa kwa yoyenera njira patsogolo kupanga;

Kodi si njira PCB kufufuza m'dera kukhudzana pakati pa leadframe ndi PCB kuteteza limadula;

anati:

○ lolondola kukhazikitsidwa njira;

× Pachithunzichi kukhazikitsidwa njira;

2. Pamene mawaya soldering kuti anawatsogolera, aliyense olowa waya ayenera payokha insulated ndi kutentha kuotcha chubu kuteteza yochepa dera kukhudzana.

Musati mtolo mawaya onse mwa mmodzi kutentha kuotcha chubu kupewa kukanikiza pakati amatsogolera anatsogolera;

Kukanikiza pakati mavuto amatsogolera anatsogolera akhoza kuwononga nyumba mkati ndi chifukwa cholephera;

anati:

○ lolondola kukhazikitsidwa njira;

× Pachithunzichi kukhazikitsidwa njira;

3. Ntchito kuima-offs (mkuyu 3) kapena spacers (mkuyu 4) pamalo adzatsekeredwa inatsogolera pamwamba PCB ya;

4. Pitirizani osachepera 3mm cl earance pakati m'munsi mwa mandala kutsogozedwa ndi woyamba kutsogolera unakhota (mkuyu. 5. mkuyu. 6)

5. Pa kutsogolera n'kupanga, zipangizo ntchito kapena jigs kugwira amatsogolera adzatsekeredwa kotero kuti mphamvu kupinda sati kuwapereka kwa disolo LED ndi nyumba yake mkati;

Osachita kutsogolera kupanga kamodzi chigawo wakhala wokwera kumtunda PCB ya;

L ead Ndimapanga Opaleshoni

1. Tsogolerani Ndimapanga Opaleshoni;

2. Kodi kupinda kumam'phunzitsa kuposa kawiri (mkuyu 7.);

3. Pa soldering, chigawo chimakwirira ndi zopalira ayenera kusiya chilolezo kupewa kuwayika kuwononga mavuto anatsogolera pa soldering (mkuyu 8);

4. kunsonga ya soldering chitsulo ayenera konse disolo epoxy;

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

6. Ngati anatsogolera adzamva mipita angapo soldering kapena nkhope njira zina pamene gawo mwina pansi kutentha chonde fufuzani ndi Best zinachititsa kuti ngakhale;
