12V 3mm LED Yofiira Yomangidwa mu Resistor DC

12V 3mm Round Top anatsogolera - Red koonekera anatsogolera

304FRD62D3L14V12 ndi voteji mkulu LED ndi wofiira emitting LED. Yerekezerani ndi ofanana wofiira SMD anatsogolera kapena kudzera-dzenje LED, 3mm chofiira kupyolera-dzenje kutsogoleredwa nawo 12V patsogolo voteji. Kuchokera chithunzi inu mukhoza kuwona, chofiira kupyolera-dzenje Zikuwoneka ngati mofanana wamba ofiira nyali LED. Chifukwa ife phukusi ang'ono anamumanga resistor mkati mwa wofiira koonekera mandala. Kutanthauza pamene ife ntchito anatsogolera ichi, sitifunanso kuwonjezera resistory aliyense, anatsogolera uyu akhoza wor mu volts 12 mwachindunji. Ngakhale ziri voteji mkulu LED, komabe limatulutsa mtundu mofanana 625nm kutsogozedwa ndi becuase wa chachikulu anatsogolera Chip mkati, 3mm chofiira anatsogolera komanso ali wapamwamba nyali yowala LED mu voteji mkulu wofiira LED. Ngati anali kufunafuna ena anamanga ku resistor wofiira LED ndi kuwala mkulu, angobwera ichi ~

Gawo la 3mm kudzera-dzenje anatsogolera:

Kudzera-dzenje anatsogolera NKHANI:

* Θ1 / 2 ZACHOKA-sxis ngodya pa zimene intenity wowala ndi theka axia wowala mwamphamvu;

Main ntchito:

* Abwino kwa backlight;

* Chizindikiritso kuwala;

* LED nyali zokongoletsera;

Tsatanetsatane mankhwala:

99,99% waya chiyero golide;

Silver yokutidwa chimango LED;

Wotchuka tchipisi kuwasindikiza;

Mkulu khalidwe epoxy;

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;
