I-SMD LED ephezulu ye-CRI Ra≥90 5050 i-White LED

Ama-5050 3 chips amhlophe i-LED 4500-5000K ane-CRI Ra≥90 ephezulu;

Le 5050WC-45K28L4W iyi-5050 emhlophe i-LED eyenziwe ngohlaka lwama-pads ayi-6. Kusukela esithombeni osibonayo, kunamaphakethe ayi-6 ngemuva kwe-LED yokuxhumeka kwesifunda. Olunye uhlangothi lwe-anode kanti olunye usayizi luzokwenza i-cathode. Uma sikhuluma nge-white SMD LED noma i-White through-hole LED, abantu bayohlala begcizelela ukushisa kombala ne-CRI. Bese kusho ukuthini ukushisa kombala ne-CRI?

Imvamisa, kuzoba nezinhlobo ezimhlophe ezizokhishwa kusuka ku-5050 white SMD LED, 3528 White SMD LED noma 5mm white through-hole LED, noma yiluphi uhlobo lwe-LED emhlophe (i-SMD LED noma i-Through-hole LED). Omunye walo mbala omhlophe uzobukeka njengombala ophuzi we-LED, ozokhipha umbala ophuzi ophuzi kakhulu wegolide, eminye yawo izokhipha umbala ohlaza okwesibhakabhaka okhanyayo kanti eminye yayo izokhipha umbala ofana nelanga. Kulokhu, sizosebenzisa ukushisa kwamakholomu ukuphazamisa lawo ma-LED amhlophe. Ukusuka ku-1000K kuye ku-20000K, izinombolo eziningi, umbala ohlaza okwesibhakabhaka i-LED emhlophe izongena ngaphakathi.

Bese kuthiwani nge-CRI?

Inkomba yokunikeza umbala (i-CRI) ibhekisa ekhonweni lokubona lomthombo wokukhanya wokubuyisela izinto elangeni. Ukuphakama kokunikezwa kombala, ukusondelana kwenani lenkomba kufinyelela kokungu-100, kulapho ikhono lokubuyiselwa kwento liqina ngokwengeziwe, futhi kuba lula emehlweni omuntu ukuhlukanisa umbala wento. Kule 5050WC-45K28L4W, sikhiqiza le LED emhlophe nge-CRI Ra≥90. Uma ufuna manje ukuthola imininingwane eminingi ngale LED, zizwe ukhululekile ukuxhumana nathi ~

Usayizi we-5050WC-45K28L4W:

Amapharamitha kagesi:

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

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

* Amandla we-Luminous alinganiswa yi-ZWL600.

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

Isicelo main:

Ukukhanya kwangemuva kwe-LED;

Izicelo zezokwelapha;

Ukukhanya Okukhomba;

Imininingwane yomkhiqizo:

99.99% ubumsulwa bensimbi yegolide;

Uhlaka olubomvu lwe-LED;

Izipisi ezinophawu oludumile;

Ikhwalithi ephezulu epoxy;

Inqubo Yokukhiqiza ye-SMD LED:

Lapho sikhiqiza le LED, kuzodingeka ukuthi silungiselele i-chip ye-LED. Lesi isinyathelo sokuqala; Okwesibili, sidinga ukulungisa i-chip kuhlaka lwethu lwe-5050 SMD LED. Futhi okwesithathu, sidinga ukusebenzisa ucingo oluhlanzekile lwegolide ukuxhuma isekethe ngaphakathi. Ngemuva kwalokho sizogcwalisa ifreyimu ye-LED nge-epoxy ne-phosphor (ukube besikhiqiza iSMD LED emhlophe), engavikela i-chip ye-LED ekulimaleni kwamandla kwangaphandle. Ngenxa yokuthi i-epoxy inguketshezi, sidinga ukuyomisa ngehhavini amahora angama-8 okungenani. Kuze kube manje, besenze izinto eziningi zokukhiqiza.

Ngemuva kokuthatha le LED kuhhavini, sidinga ukubeka yonke i-LED emshinini wokuhlunga ukuze sihlukanise i-LED ngomgqomo ohlukile (noma i-voltage).

UKUPHATHA IZINYATHELO:

Qhathanisa ne-epoxy encapsulant eqinile futhi eqinile, i-silicone ithambile futhi iyaguquguquka i-Althouth i-characteristiec yayo inciphisa kakhulu ukucindezeleka okushisayo, isengozini enkulu yokonakaliswa ngamandla amakhulu womshini. Ngenxa yalokhu, izindlela zokuphatha ezikhethekile zidinga ukubonwa ngesikhathi sokuhlangana usebenzisa 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 aveziwe. 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 ukubambana 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 njenge-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 ngaphakathi kwamahora angama-24 wokuvulwa.
