Super Bright 3mm daloolka daloolka leh ee loo yaqaan 'Red Red Diffused LED'

Super Bright 3mm casaan leh Lens Led diffused

3mm LED 304FRD-8 waa heer aad u dhalaalaya 3mm LED cas oo ku jira dufankayaga. Waa kuwee LED -ga cas ee caadiga ah oo leh muraayad gaduudan oo aasaasi ah oo hore loo qiimeeyay 20mA. Haddii 3mm-da kale ee cas ee daloolka leh aysan u iftiimin codsigaaga. Fadlan middan hubi.

Isbarbar dhig 3mm 625nm LED kale, kan 304FRD- wuxuu gaari karaa dhalaalka 700-1000mcd marka aad iftiimiso 20mA. Sababtoo ah iftiinkan aadka u iftiimaya, Lammadan LED -ku waxay ku habboon yihiin mashruuca iftiinka dambe ee LED, mashruuca tilmaamaha LED -ka iyo dalabka nalalka LED. Isla mar ahaantaana, tan yar ee loo yaqaan 'Red Throguh-hole LED' ayaa sidoo kale u fiican qaar ka mid ah mashruuca DIY. Si aad u iftiimiso 3mm LED-da daloolka cas, waxaad u baahan tahay uun tilmaam awood, dareemayaal opto-elektaroonig ah.

Miyaad u baahan tahay xoogaa casaan aad u dhalaalaya oo leh dhexroor 3mm ah? Nala soo xiriir wixii faahfaahin dheeraad ah oo ku saabsan ~

Horumarinta wax-soo-saarka ee daloolka daloolka LED:

Isbarbar-dhig ku samee SMD LED, wax-soo-saarka LED-ka-daloolka ayaa noqon doona mid aad u dhib badan. Taasoo micnaheedu yahay waxay qaadan doontaa horumar wax -soo -saar oo dheeri ah iyo waqti wax -soo -saar:

Ugu horreyntii, waxaan u baahannahay inaan diyaarino chip -ka LED -ka (tani waxay la mid noqon doontaa soo -saarka SMD LED ); Marka labaad, waxaan u baahnaan doonnaa inaan ku ridno guntinta LED -ka guluubka LED -ka, ka dibna waxaan u baahan doonnaa silig dahab saafi ah si aan ugu xirno cathode iyo anode of frame LED. Waxaa jira wax ka duwan, Soo -saarka SMD LED, waxaan u baahanahay inaan ku dhejinno epoxy -ga shaxanka LED -ka oo aan sugno ilaa uu ka engejiyo foornada. Si kastaba ha noqotee, Nalalka LED -ka, waxaan u baahanahay inaan ku shubno epoxy -ga caaryada muraayadda oo aan wax walba ku ridno foornada ugu yaraan 8 saacadood illaa ay ka engegaan. Intaas ka dib, waxaan u baahanahay inaan ka fogeynno foornada oo aan ka saarno LED caaryada. Ka dibna waxaan u baahanahay inaan jarno biinanka LED si ay u sahlanaato tijaabintooda.

Ugu dambeyntii, waxaan helnay LED. Si loo hubiyo tayada iyo lebiska sida ugu wanaagsan ee loo baahan yahay. Waxaan sidoo kale u baahanahay inaan ku shubno dhammaan LED -ka mashiinka kala -soocidda oo iyaga waxaan ku heli doonnaa LED -ga oo leh weel isku mid ah.

Xaaladaha Kaydinta:

1. ka fogow soo -gaadhista joogtada ah ee jawiga qoyaanka oo ka ilaali badeecada inay si degdeg ah ugu gudubto heerkulka deegaanka;

2. Laydhka waa in lagu kaydiyaa heerkulka ≤30 ℃ iyo qoyaan qaraabo <60%℃;

3. Badeecadda ku jirta xirmadii asalka ahayd ee la shaabadeeyey waxaa lagu talinayaa in lagu soo ururiyo 72 saacadood gudahood furitaanka;

4. Badeecadda ku jirta xirmo furan in ka badan toddobaad waa in lagu dubaa 6-8 saacadood 85-10 ℃;

HABKA FIRINTA LED

1, Qulqulka qulqulka LED -ka waa inuu la jaanqaadaa garoonka godadka dhajinta ee PCB -ga inta lagu jiro meelaynta qaybaha ;

Leedh-sameynta waxaa laga yaabaa in loo baahdo si loo hubiyo in garoonka leedhka uu la mid yahay garoonka daloolka ;

Tixraac shaxanka hoose ee hababka sameynta leedhka habboon ;

Ha u marin raadinta PCB-ga aagga xiriirka u dhexeeya leedhka iyo PCB-ga si looga hortago wareegyada gaagaaban ;

La xusay:

Method Habka saxitaanka si sax ah;

Method Habka fidinta oo aan sax ahayn;

2 Marka fiilooyinka lagu iibiyo Laydhka, isku-xidhka silig kasta waa in si gooni ah loogu dahaadhaa tuubada kulaylka si looga hortago taabashada wareegga gaaban.

Ha ku xidhmin labada fiilo hal tuubbo yareyneysa kuleylka si aad uga fogaato in la qanciyo hoggaamiyeyaasha LED -ka ;

Cidhiidhiga ku dhagan hogaamiyaasha rasaasta ayaa dhaawici kara dhismayaasha gudaha oo sababi kara fashil ;

La xusay:

Method Habka saxitaanka si sax ah;

Method Habka fidinta oo aan sax ahayn;

3. Isticmaal istaag (Jaantuska 3) ama boosaska (Jaantus 4) si aad si ammaan ah u dul dhigto LED-ka PCB-ga ;

4. Joogso ugu yaraan 3mm cl climation inta u dhaxaysa saldhigga muraayadda LED -ka iyo leexashada hogaanka koowaad (Sawirka 5. Sawirka 6)

5. Marka la samaynayo macdanta `` lead '', isticmaal qalab ama jijooyin si aad si ammaan ah u xajisid hoggaamiyeyaasha si xoogga foorarsiga aan loogu gudbin muraayadda LED -ka iyo dhismayaasha gudaha ;

Ha sameynin sameynta macdanta `` lead '' marka qeybta la saaro PCB -ga ;

L EAD U samaynta Hannaanka

1. Habraacyada Samaynta Hoggaaminta ;

2. Ha leexin tilmaamaha in ka badan laba jeer (Jaantus. 7 );

3. Inta lagu jiro alxanka, daboollada iyo kuwa haysta waa inay ka baxaan oggolaanshaha si looga fogaado in culayska waxyeellada leh la saaro LED -ka inta la xirayo (Jaantus 8) ;

4. Caaradda birta wax iibisa waa inaysan marna taaban epoxy lens -ka ;

5. Nalalka daloolka leh ee LED- yada ma aha kuwo la jaanqaadi kara alxanka dib-u-celinta ;

6. Haddii laydhku mari doono kaarar badan oo alxanka ah ama wajihi doona geedi socodyo kale oo laga yaabo in qaybta lagu kululeeyo kulayl aad u badan fadlan ka hubi LED -ka ugu fiican si loo waafajiyo ;
