5050 SMD LED Cyan LED 490nm AmaChips amathathu

I-490nm LED ene-5050 SMD LED ama-chips amathathu ngaphakathi:

I-520nm LED iyi-LED eluhlaza engaxutshiwe, i-470nm LED ne-480nm i-LED iluhlaza okwesibhakabhaka i-LED. Ngemuva kwalokho umbala onjani phakathi kwe-LED eluhlaza noluhlaza okwesibhakabhaka? Njenge-500nm LED, i-495nm LED noma i-490nm LED?

I-cyan LED futhi ibika ukuthi i-waxelength 490nm ingakhuphula amandla amaseli ngokulandelana futhi ibe nomthelela omuhle ku-metaboliso. Ngaphezu kwalokho, ingalinganisa uketshezi, isikhumba esizolile nokulawula uwoyela. Kungakho iningi labantu lisebenzisa le-cyan LED kumaskhi we-LED.

Ngakolunye uhlangothi, le-LED inezichips ezintathu ngaphakathi futhi ingalawula ngopini ngamunye ongu-3 ohlangothini lwe-SMD LED. Uma uyikhanyisa, izokhipha umbala omuhle. Okungasetshenziswa kuningi lephrojekthi yokukhanyisa emuva ye-LED kanye nephrojekthi yokukhanyisa i-LED yendlu noma ibha.

Usayizi we-5050 SMD LED ama-chip amathathu we-LED:

* Leli cala le-SMD LED litholakalela ne-blue SMD LED, i-Amber LED, i-UV LED ne-IR LED ect. *

Izici:

Ubukhulu: 5.0x5.0xh1.3mm;

Umbala we-wavelength: i-490nm LED

Izinto ze-Chip: InGaN;

Ukuthembeka okuphezulu, ukuqina kwemisebe ephezulu namandla aphansi aya phambili.

Amapharamitha kagesi:

* Ukudonswa phambili kwenkomfa yamanje: Umsebenzi ongu-1% nobubanzi bePulse = 10us.

* Umhlangano weSoldering: Umhlangano weSoldering kufanele uqedwe ngamasekhondi ama-3 ku-260 ℃

* Amandla akhanyayo alinganiswa yi-ZWL600.

* I-λD itholakala kumdwebo we-CIE chromaticity futhi imelela ubude obude obuchaza umbala wedivayisi.

Isicelo esiyinhloko se-cyan LED:

Indawo yemaski yobuhle; Ukukhanya okukhombayo; Ukukhanya kwe-LED emuva; Umhlobiso we-LED light ect;

Ifana nenye i-SMD LED, yonke imikhiqizo yethu iyimikhiqizo enentambo yegolide emsulwa yokuxhuma kwangaphakathi kwesekethe. Kukhona ama-chip amathathu we-LED ngaphakathi kwale LED. Kusukela esithombeni osibonayo, kune-chip encane emithathu ngaphakathi futhi ucezu ngalunye lwaluxhunywe ngocingo lwegolide. Uma ufuna i-cyan SMD LED noma i-cyan through-hole LED, sicela uxhumane nathi ukuthola eminye imininingwane ~ Ikhwalithi yethu ngeke ikuvumele udumazeke!

UKUPHATHA IZINYATHELO:

Qhathanisa ne-epoxy encapsulant eqinile futhi eqinile, i-silicone ithambile futhi iguquguqukayo i-Althouth i-characteristiec yayo inciphisa kakhulu ukucindezeleka okushisayo, isengozini enkulu yokonakaliswa ngamandla amakhulu womshini. Ngenxa yalokhu, izindlela zokuphatha ezikhethekile zidinga ukubonwa ngesikhathi sokuhlangana kusetshenziswa imikhiqizo yeLed silicone efakwe ngaphakathi. Ukwehluleka ukuthobela kungaholela ekulimaleni nasekuhlulekeni kwangaphambi kwesikhathi kwe-led

1. Phatha into eceleni kwezindawo eziseceleni usebenzisa i-forceps noma amathuluzi afanele.

2, Ungathinti ngqo noma uphathe ubuso belensi abicah. Kungalimaza izifunda zangaphakathi.

I-3, Ungafaki ndawonye ama-PCBS ahlanganisiwe aqukethe ama-LED adaluliwe. Umthelela ungaklwebha amalensi abicah noma ulimaze ukujikeleza kwangaphakathi.

4, 4-A Ububanzi obungaphakathi kumbhobho wombhobho weSMD akumele budlule ubukhulu be-LED ukuvimbela ukuvuza komoya;

Kuphakanyiswa impahla ephathekayo engu-4-BA yethiphu lombhobho ukugwema ukuthwebula noma ukulimaza ubuso be-LED ngesikhathi sokuthatha iveni.

4-C Ubukhulu besakhi kufanele buhlelwe ngokunembile emshinini wokukhetha nokubeka indawo ukuze kuqinisekiswe ukuthathwa okuqondile futhi kugweme ukulimala ngesikhathi sokukhiqizwa;

4-D Njengoba ukufakwa kwe-silicone kufakwa amagesi, ezinye izinto ezonakalisayo ezifana ne-H2S zingahle zonakalise i-plationg yesiliva ye-leadframe. Ukunakekelwa okukhethekile kufanele kuthathwe uma kusetshenziswa i-LED ene-silicone encapsulation eduze kwezinto ezinjalo.

5, Sicela i-aviod iqhubeke nokuchayeka emswakama oshisayo futhi ugcine umkhiqizo kude nokushintshwa kokubuyisa ekushiseni kwe-ambiemt.

6, Umkhiqizo kwiphakheji yokuqala evaliwe unconywa ukuthi uhlangane phakathi kwamahora angama-24 wokuvulwa.
