Ungazikhetha njani iitshiphusi ze-LED ezikwiMgangatho oPhezulu

Ubhubhani we-COVID-19 wonyuse umdla kwizixhobo zokubulala iintsholongwane ze-UVC ze-LED, ukutyhala i-UVC ye-LED—imveliso isekwinqanaba lokuqala lophuhliso olukhawulezayo—phambili.

Ukusukela ukuba itekhnoloji ye-UVC ye-LED isekubuntwaneni bayo, akukho migangatho yelizwe okanye yoshishino ekhoyo. Ukongeza, njengoko kungekho mgangatho wamkelweyo wovavanyo wokulinganisa ukuguquguquka okuqaqambileyo kunye nobunzulu beetshiphusi ze-UVC ze-LED, akukho nasiphi na isixhobo sovavanyo se-UVC esithobela umgangatho.

Ziziphi iinguqu ezikhoyo phakathi kwee-chips ze-LED (SMDs)? Loluphi uhlobo endimele ndilukhethe?

Uya kufumanisa ukuba imakethi izaliswe ziintlobo ezininzi ezididayo ezinokwenzeka kuluhlu lwamaxabiso ahlukeneyo ukuba ukhangela iibhalbhu zeLed zeprojekthi yokuhlala okanye yorhwebo. Kusenokuhenda ukukhetha isilungiso se-LED esinexabiso eliphantsi. Nangona kunjalo, ukulungiswa kwe-LED ngexabiso eliphantsi akusoloko kuyeyona ndlela ilungileyo kuba umgangatho wokukhanya kwe-LED uhluka kakhulu phakathi kwabavelisi. Xa ukugcinwa kwamandla, ukusebenza, ukugcinwa, kwaye kwezinye iimeko, iindleko zokutshintshwa ziqwalaselwa, ukulungiswa kwe-LED engabizi kunokuphelisa ixabiso elide kwixesha elide. Ukuqinisekisa ukuba ufumana ixabiso elilungileyo lemali yakho kunye nokufezekisa iprojekthi yokukhanyisa i-LED eyimpumelelo, kubalulekile ukuvavanya ngononophelo kwaye uthelekise iimpawu zezixhobo ze-LED oziqwalaselayo.

Iintlobo ze-chip ze-LED ezivela kuluhlu olubanzi lwe Abavelisi abakhokela  ingasetyenziselwa ukwenza ukukhanya kwe-LED strip.

Ngokuchasene neentlobo ezimbini ze-chip ezidumileyo kwiimarike ze-LED tape, i-3528 kunye ne-5050, siya kubonisa ulwahlulo oluphambili phakathi kwabo kumacandelo alandelayo.

Umahluko uthelekisa LED 3528 nge 5050

Iichips ezininzi ze-LED zingasetyenziselwa ukwenza izibane ze-LED strip. Ubungakanani be-chip buboniswa ngamanani owabonayo, njenge-3528 kunye ne-5050. Iisayizi ozibonayo ngasentla ziipaneli zesitayile ezindala ebeziqhelekile ixeshana. Okwangoku, iichips ze-LED kubukhulu be-2835, 3014, 5630, kunye ne-3020 zihlangene ngakumbi kwaye zisebenza. Nganye ineengenelo xa isetyenziswe ngokuchanekileyo. Abanakukwazi ukulawulwa "enye" ​​chip.

Ziyasetyenziswa, ngakumbi izibane zokutshintsha umbala we-RGB, xa ufuna kuphela ukukhanya okuncinci kwindawo yakho yokusebenza. I-LED ye-5050 ifaneleke ngokukodwa ukukhanyisa iindawo ezinokuthi zichaphazeleke kumazinga aphezulu okukhanya kwendalo ukususela, ngokwethiyori, xa uthelekisa imicu enexabiso elifanayo leetshiphusi, ii-SMD 5050 LEDs zinokukhupha ukukhanya okuphindwe kathathu kune-3528. imicu. Kukho kuphela inani elithile elinokungena kwi-PCB ngenxa yobungakanani bayo obandisiweyo. Ii-5050s zinezithintelo zokukhanya xa zisetyenziswa ngolu hlobo.

Nangona zivelisa ubushushu obuninzi kuneetshiphusi ezincinci, nangona kunjalo zikwenza oko ngesantya esisezantsi kakhulu kunezinye iintlobo zokukhanyisa. Ukuhambisa ubushushu kude neechips, ezi LED zifuna iPCB etyebileyo.

Ngokuchaseneyo ne-3528 LEDs, ii-5050s zinokudibanisa iitshiphusi ezintathu ezihlukeneyo ngaphakathi kwesikhongozeli ukuvelisa izigidi zemidibaniso yombala enokwenzeka.

Ii-LED ze-3528 ze-SMD kwi-high density zingcono kwizicelo zombala omnye, nangona i-chip ye-5050 ingasetyenziselwa izicelo ezifuna umbala omnye kuphela.

Ivavanywa njani itshiphu ye-UVC ye-LED?

Umlinganiselo weempawu zetshiphu ze-I-V zithe ngqo. Umhloli unokusetyenziselwa ukulinganisa ngokuthe ngqo, okanye inkqubo yokuvavanya ngokuthe ngqo eyenziwe ngokuqhubekayo ngoku kunye ne-voltmeter inokwakhiwa. Abavelisi bokupakishwa kwe-LED banokusebenzisa i-voltage kunye nenkqubo yovavanyo lwangoku lwe-Leeds photoelectric uphawu lokuvavanya ngokucokisekileyo, umthombo wamandla opholileyo, emva koko bazobe ijika le-I-V yeempawu emva kokulinganisa amandla ombane ahambelanayo ngokutshintsha okwangoku. Inkqubo yenziwe ngumthombo wamandla wangaphandle we-drive, i-LED yoxinzelelo lokukhanya-i-strain tester, kunye ne-EVERFINE U-20 imitha ye-irradiance enzulu ye-UV.

Isixhobo sokuguqula i-angle kunye nomgama sibandakanyiwe kunye nomhloli wokusabalalisa ukukhanya kwe-LED, ukwenza imilinganiselo ibe lula.

Uxinzelelo lokukhanya lwe-LED - umvavanyi woxinzelelo uneengile kunye nesixhobo sohlengahlengiso lomgama, okwenza kube lula ukulinganisa ubunzulu bemitha kwii-engile ezahlukeneyo kunye nemigama. I-DC ezinzisiweyo yonikezelo lwamandla inika amandla inkqubo yovavanyo. Uhlengahlengiso lwemveliso yonikezelo lwamandla luvumela ulawulo olulungileyo lwegalelo langoku kwi-LED.

Iichips ze-LED zongamela ukuguqula umbane ube kukukhanya, kwaye zilawula umbala kunye nomgangatho wokukhanya okukhutshwa yi-LED. Nangona baninzi abavelisi be-chip be-LED emhlabeni wonke, kukho umahluko omkhulu kumgangatho we-chip ye-LED kunye nokusebenza kwimarike. Abenzi abaphezulu bee-chips ze-LED bafumaneka e-China naseMzantsi Korea, kunye neenkampani ezaziwayo-kakuhle e-United States naseJapan.

Kutheni le nto kubalulekile ukukhetha izilungiso ze-LED ezisebenzisa iichips zeprimiyamu ze-LED?  

Naphakathi kwee-chips ze-LED ezivela kwibhetshi enye, kukho umahluko oqhelekileyo kumbala okhanyayo, ukuqaqamba, kunye nombane ngexesha lenkqubo yokuvelisa.

imigqomo" ngokweempawu zabo. Ezona "migqomo" zimxinwa zisetyenziselwa iitshiphusi ze-LED ezigqwesileyo, eqinisekisa ukuba naluphi na utshintsho phakathi kweetshiphusi luncinci kangangokuba alubonakali. Nokuba ingakanani iprojekthi yakho yokukhanyisa i-LED, unokuqinisekisa ukusebenza rhoqo kwe-LED ngokukhetha izilungiso ze-LED usebenzisa iitshiphusi ze-LED ezikumgangatho ophezulu.

Apho unokuthenga iitshiphusi ze-LED ezikumgangatho ophezulu

Enye ephezulu Abavelisi abakhokela  ye-UV ye-LED e-China yiTianhui Electronics . Iminikelo yethu ibandakanya uphando kunye nophuhliso kwisayensi, Uncedo lobuGcisa, kunye nenkonzo yoYilo Ukuthengiswa kwezinto zombane 5. Isicelo sesibane se-UV kwibhodi ye-microcircuit. Singomnye we-Asia ehamba phambili ngokugqithisileyo Imodyuli ekhokelweyo  ukubonelela abathengi nge Isisombululo se-UV LED , iimpahla, kunye neenkonzo. Iminikelo yethu ibandakanya i-UVA, i-UVB, kunye ne-UVC ukusuka kumaza amafutshane ukuya kumaza amade kunye neempawu ezipheleleyo ze-UV ze-LED ukusuka kumandla aphantsi ukuya phezulu. Iimfuno zabathengi zezona zinto ziphambili kuthi, kwaye sizinikele ekunikeni inkonzo ebalaseleyo.
