3528 SMD Daylight White LED PLCC2 6000K

3528 SMD emini White LED PLCC2 6000-6500K

Uyazi ukuthi yini eyenza ikhwalithi engcono kakhulu ye-SMD LED? Intambo yegolide ngaphakathi yokubopha, ukuzinza kokukhipha okuzinzile kokukhanyisa, ifreyimu ye-LED yethusi ne-epoxy esezingeni eliphakeme phezulu yokuguqula i-chip. Konke lokhu kwenza ikhwalithi enhle ye-3528 White SMD LED.

Ku-White SMD LED, sijwayele ukuhlukanisa i-LED emhlophe ngezigaba ezintathu: i-whtie efudumele, imhlophe emini noma imvelo imhlophe futhi ipholile imhlophe ngokuya ngezinga lokushisa kombala. Ama-CCT angaphansi kuka-2700K wonke angaphansi kwe-LED emhlophe efudumele, ngaphansi kuka-6500K singayiqamba njenge-LED emhlophe yemvelo nangaphezulu kuka-7000K singayibiza ngokuthi yi-cool whtie LED. Ngesinye isikhathi ukushisa kombala kwe-LED emhlophe epholile kungafinyelela ku-20000K. Kuzoba bule-ish kakhulu lapho umbala ufika kulokho.

Umbala omhlophe ohlukile uzolungela ngesikebhe esihlukile noma ekamelweni elihlukile. Isibonelo, uma ukhiqiza ithubhu ethile ye-LED yehhovisi, igumbi lokufundela, igumbi lokuhlangana, khona-ke i-LED emhlophe epholile izolungela kakhulu icala lakho. Futhi uma uhlose igumbi lokuphumula, ikhaya, ihhotela, khona-ke okumhlophe okufudumele kuzoba ngcono kakhulu. Futhi kokunye ukuvivinya umzimba, isibhedlela, indawo yokulala, ukukhanya kwasemini okumhlophe noma i-LED emhlophe yemvelo kuzoba kuhle ~

Amapharamitha Wobukhulu:

* Leli cala le-SMD LED liyatholakala nakwi-IR LED, i-UV LED, iBlue MSD LED kanye ne-Amber LED production.

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.

Inqubo Yokukhiqiza ye-SMD LED:

Isicelo:

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 somhlangano kusetshenziswa imikhiqizo yeLed silicone efakwe ngaphakathi. Ukwehluleka ukuthobela kungaholela ekulimaleni nasekuhlulekeni ngaphambi kwesikhathi kwalowo oholile

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

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 kahle 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.
