Ilensi eKhanyayo eKhanyayo eyi-3mm eBlue yeBlue yeBlue

I-3mm yeBlue ejikeleze umngxunya we-LED ene-lens engama-40 eluhlaza okwesibhakabhaka:

Le 304BD46D2L12 zii-LED eziluhlaza ezine-lens eluhlaza okwesibhakabhaka. Njengoko sibona emfanekisweni, lo mbala weelensi ujongeka njengokukhanya kwamanzi aluhlaza hayi okwesibhakabhaka esinzulu. Ewe kunjalo, ukuba ufuna iilensi ezingacacanga eziluhlaza ze-460nm-470nm LED uzive ukhululekile ukusazisa ~ Singakuvelisela yona. Kwelinye icala, ngexesha lokuvelisa, sivelisa le blue nge-hole emngxunyeni ene-40 degree angle angle, enokuqinisekisa ukuba inokukhanyisa indawo engaphezulu. Kwikona yokujonga, izidanga ezingama-20 izidanga ezingama-30, ezingama-40, ezingama-60 okanye ezingama-90 dgree zonke ziyafumaneka. I-engile yokubukela eyahlukeneyo iya kukhupha indawo eyahlukeneyo yokukhanya, isidanga esincinci, indawo encinci yokukhanya kunye nomgama omde wokukhanyisa. Ukuba ufuna enye yale LED eluhlaza okwesibhakabhaka kwiprojekthi yakho yokukhanyisa, qha ga mshelana nathi ngolwazi olungakumbi malunga ~

Izinto eziluhlaza okwesibhakabhaka nge-hole:

Isicelo:

Imaski yobuhle be-LED;

Ukukhanya kwe-LED yangasemva;

Inkqubela phambili yokuvelisa kwe-LED emngxunya:

Thelekisa kunye ne-SMD ye-LED, ukujikeleza kwe-LED kwimveliso kuya kuba nzima ngakumbi. Oko kuthetha ukuba kuya kuthatha inkqubela phambili ngakumbi kwimveliso 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. thintela ukuqhubeka kokuchaphazeleka kobume obufumileyo kunye nokugcina imveliso ikude kutshintsho 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-pitch ekhokelayo ye-LED kufuneka ihambelane nomgangatho wemingxunya ekhulayo kwi-PCB ngexesha lokubekwa kwecandelo;

Ukwenziwa kwelothe kunokufuneka ukuba kuqinisekiswe ukuba inqaku lokukhokela lihambelana nomngxunya;

Jonga lo mzobo ungezantsi weenkqubo ezifanelekileyo zokwenza iinkqubo;

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

Qaphela:

Mount Indlela echanekileyo yokufaka;

× Indlela yokufaka engalunganga;

2. Xa iintambo ze-soldering kwi-LED, intambo nganye yocingo kufuneka ifakwe ngokwahlukileyo ngombhobho wokunciphisa ubushushu ukuthintela ukudibana 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 4) ukubeka i-LED ngokhuseleko kwi-PCB;

4. Gcina ubuncinci bokususwa kwe-3mm phakathi kwesiseko seelensi ze-LED kunye nokugoba okokuqala kwelitye (Ikhiwane. 5. Ikhiwane. 6)

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

Sukuyenza indawo ekhokelayo yakuba nje icandelo lifakwe kwi-PCB;

L nethoba Owenza Iinkqubo

1. INkqubo yokuKhangela iiNkqubo;

2. Sukugoba izikhokelo ngaphezulu 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. Ii-LED zemingxunya engahambelaniyo 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;
