I-3mm yangaphakathi-emngxunyeni we-LED oBomvu oSasazekileyo kuMgangatho oPhakamileyo we-LED

I-3mm ebomvu i-LED edibeneyo enokukhanya okuphezulu kunye nomgangatho, iRoHs esemgangathweni;

Le 304URD ijongeka ngokufana ne-304NRD, Zonke zinobungakanani obulinganayo, iilensi ezibomvu ezahlukileyo kwaye ziye zafumana ukukhanya okufanayo xa uzikhanyisa. Ke yintoni eyahlukileyo phakathi kwezi zibomvu nge-hole hole?

Kuqala, f okanye indleko, i-304URD iya kufumana ixabiso leyunithi ephezulu kune-304NRD.

Kwiwaranti, i-304URD ifumene iwaranti yeminyaka emi-5. Kodwa nge-304NRD, inonyaka omnye kuphela. Kwaye kwelinye icala, i-304URD iya kusebenza ngcono kune-304NRD kwisibane.

Ukongeza, ukuba ufuna le 3mm 625nm ye-LED ukuhlangabezana nemigangatho yeRoHs kwiprojekthi yakho, i-304URD iya kuba ngcono kwizicelo zakho. Sisebenzisa ucingo olucocekileyo ngaphakathi ngaphakathi ukudibanisa kunye nomgangatho ophezulu we-epoxy, yonke le nto iya kuhlangabezana nomgangatho ophezulu.

Ke, ukhetha ntoni, 304URD okanye 304NRD?

Ubungakanani be-3mm nge-hole hole:

Inkqubela phambili yokuvelisa i-LED emngxunyeni:

Thelekisa kunye ne-SMD ye-LED, ukuveliswa kwemingxunya ye-LED kuya kuba nzima. Oko kuthetha ukuba kuya kuthatha inkqubela phambili yemveliso kunye nexesha lokuvelisa:

Okokuqala, kufuneka silungiselele i-chip ye-LED (oku kuyakufana nemveliso ye-SMD ye-LED ); Okwesibini, kuya kufuneka sibeke i-chip ye-LED kwisakhelo se-LED, emva koko siyakufuna ucingo olucocekileyo lwegolide ukudibanisa i-cathode kunye ne-anode yesakhelo se-LED. Kuza ngokwahlukileyo, kwimveliso ye-SMD ye-LED, kufuneka sibeke i-epoxy kwisakhelo se-LED kwaye silinde de yome nge-oveni. Nangona kunjalo, kwizibane ze-LED, kufuneka sitofe i-epoxy ekubunjweni kwelensi kwaye sibeke zonke izinto ehovini ubuncinci iiyure eziyi-8 de zome. Emva koko, kufuneka sibacofe ehovini kwaye sikhuphe i-LED ngaphandle kwesikhunta. Kwaye emva koko kufuneka sisike izikhonkwane ze-LED ukuze kube lula ukuzivavanya.

Okokugqibela, siyifumene i-LED. Ukuze uqiniseke ukuba umgangatho kunye nomgangatho ofanelekileyo njengoko kufuneka. Kuya kufuneka sibeke zonke i-LED kumatshini wokwahlula kwaye siyakufumana i-LED ngemigqomo efanayo.

Imiqathango yokugcina:

1. kuthintele ukuvezwa okuqhubekayo kwimeko yokufuma yokugcina amanzi kwaye ugcine imveliso kude notshintsho olukhawulezileyo kubushushu bemo;

2. Ii-LED kufuneka zigcinwe kubushushu ≤30 ℃ kunye nokufuma okumalunga <60% ℃;

3. Imveliso kwiphakheji yokuqala etywiniweyo iyacetyiswa ukuba ihlanganiswe kwiiyure ezingama-72 zokuvulwa;

4. Imveliso kwiphakheji evuliweyo ngaphezulu kweveki kufuneka ibhakwe iiyure eziyi-6-8 nge-85-10 ℃;

INDLELA YOKUTHUTHA I-LED

I-1, i -lea d pitch ye-LED kufuneka ihambelane nomgangatho wemingxunya ekhulayo kwi-PCB ngexesha lokubekwa kwezinto ;

Ukwenziwa kwelothe kunokufuneka ukuba kuqinisekiswe ukuba inqaku lokukhokela lihambelana nomngxunya ;

Jonga lo mzobo ungezantsi weenkqubo ezifanelekileyo zokwenza inkqubo ;

Musa ukuhambisa umkhondo we-PCB kwindawo yoqhakamshelwano phakathi kwegama lesikhokelo kunye ne-PCB ukukhusela iisekethe ezifutshane ;

Qaphela:

Mount Indlela echanekileyo yokufaka;

× Indlela yokufaka engalunganga;

2. Xa iintambo ze-soldering kwi-LED, udibaniso ngalunye lwentambo kufuneka lubekwe ngokwahlukeneyo ngombhobho osasaza ubushushu ukuthintela ukunxibelelana kwesekethe emfutshane.

Sukuziqokelela zombini iingcingo kwityhubhu enye yokunciphisa ubushushu ukunqanda ukutswina izikhokelo ze-LED ;

Ukucofa uxinzelelo kwizikhokelo ezikhokelwayo kunokonakalisa ulwakhiwo lwangaphakathi kwaye kubangele ukusilela ;

Qaphela:

Mount Indlela echanekileyo yokufaka;

× Indlela yokufaka engalunganga;

3. Sebenzisa ii-stand-offs (Umzobo 3) okanye izithuba (Spacers 4) (ikhiwane lesi-4) ukubeka i-LED ngokhuseleko kwi-PCB ;

4. Gcina ubuncinane be-3mm cl ear phakathi kwesiseko se-lens ye-LED kunye nokugoba kokuqala (i-Fig. 5. Ikhiwane. 6)

5. Ngexesha lokwenziwa kwelothe, sebenzisa izixhobo okanye iijig ukubamba izikhokelo ngokukhuselekileyo ukuze amandla okugoba angadluliselwa kwilensi ye-LED nakwizakhiwo zayo zangaphakathi ;

Musa ukwenza ilothe bokwakha nje ukuba icandelo lifakwe kwi-PCB ;

L nethoba Owenza Iinkqubo

1. Iinkqubo zokwenza iNkokeli ;

2 . Musa ukugoba izikhokelo ngaphezu kokuphindwe kabini (Ikhiwane. 7 );

3. Ngethuba lokufaka i-soldering, amaqweqwe kunye nabanikazi kufuneka bashiye ukucoceka ukunqanda ukubeka uxinzelelo kwi-LED ngexesha le-soldering (Umzobo 8) ;

4. Incam yesinyithi esine-soldering akufuneki ichukumise i-lens epoxy ;

5. Ngombobo we-LED s awuhambelani ne-soldering ;

6. Ukuba i-LED iya kudlula kwi-soldering pass okanye ijongane nezinye iinkqubo apho icandelo linokuthi lifakwe kubushushu obukhulu nceda ujonge kwi-Best LED yokuhambelana ;
