Ungawakhetha Kanjani Ama-chips e-LED aphezulu

Umqedazwe we-COVID-19 ukhulise intshisekelo kumadivayisi e-UVC okubulala amagciwane e-UVC, ephusha i-UVC LED—umkhiqizo osasezigabeni zokuqala zokukhula ngokushesha—phambili.

Njengoba ubuchwepheshe be-UVC LED busaqala, awekho amazinga kazwelonke noma embonini. Ukwengeza, njengoba lingekho indinganiso yokuhlola eyamukelwayo yokulinganisa ukuguquguquka okukhazimulayo nokuqina kwama-chips e-UVC LED, azikho izisetshenziswa zokuhlola ze-UVC LED ezithobelana nezinga.

Yiziphi izinguquko ezikhona phakathi kwama-LED chips (SMDs)? Iluphi uhlobo okufanele ngilukhethe?

Uzothola ukuthi imakethe igcwele izinhlobonhlobo ezididayo zamathuba ezinhlotsheni zamanani ezehlukene uma usesha ama-Led amaphrojekthi okuhlala noma ezohwebo. Kungase kulingeke ukukhetha uhlobo lwe-LED olushibhe kakhulu. Kodwa-ke, ukulungiswa kwe-LED eshibhile akuyona njalo inketho engcono kakhulu ngoba izinga lokukhanyisa kwe-LED lihluka kakhulu phakathi kwabakhiqizi. Uma ukonga amandla, ukusebenza, ukunakekelwa, futhi kwezinye izimo, izindleko zokushintshwa zicatshangelwa, ukulungiswa kwe-LED okungabizi kungase kugcine kubiza kakhulu ngokuhamba kwesikhathi. Ukuqinisekisa ukuthi uthola inani elihle ngempela lemali yakho kanye nokufeza iphrojekthi eyimpumelelo yokukhanyisa kwe-LED, kubalulekile ukuhlola ngokucophelela futhi uqhathanise izici zezintambo ze-LED ozicabangelayo.

Izinhlobo ze-chip ze-LED ezivela ebangeni elibanzi le Abakhiqizi be-uv  ingasetshenziswa ukudala ukukhanyisa kwe-LED strip.

Ngokuqhathanisa izinhlobo ezimbili zama-chip ezaziwa kakhulu emakethe zetheyiphu ye-LED, i-3528 ne-5050, sizobonisa umehluko obalulekile phakathi kwazo ezigabeni ezilandelayo.

Umehluko uqhathanisa i-LED 3528 ne 5050

Ama-chips amaningana e-LED angasetshenziswa ukwenza ukukhanya kwe-LED strip. Ubukhulu be-chip buboniswa izinombolo ozibonayo, njenge-3528 kanye ne-5050. Osayizi obabona ngenhla bangamaphaneli esitayela amadala abejwayelekile isikhathi eside. Njengamanje, ama-LED chips ngobukhulu be-2835, 3014, 5630, no-3020 ahlangene kakhulu futhi asebenza kahle. Ngayinye inezinzuzo lapho isetshenziswe ngendlela efanele. Azikwazi ukubuswa zonke yi-chip "eyodwa".

Zisetshenziswa, ikakhulukazi izibani ezishintsha umbala we-RGB, lapho udinga kuphela ukukhanya okuncane kwendawo yakho yokusebenza. I-5050 LED ifaneleka ngokukhethekile ukukhanyisa izindawo ezingase zibe lula emazingeni aphezulu okukhanya kwemvelo njengoba, ngokwembono, uma uqhathanisa amapheshana anenani elifanayo lama-chips, ama-SMD 5050 LEDs angaletha ukukhanya okuphindwe kathathu kunakwe-3528. imichilo. Kunenombolo ethile kuphela engangena ku-PCB ngenxa yosayizi wayo onyukile. Ama-5050 anemikhawulo ethile yokukhanya lapho esetshenziswa ngale ndlela.

Noma zikhiqiza ukushisa okuningi kunama-chips amancane, noma kunjalo zikwenza ngenani eliphansi kakhulu kunezinye izinhlobo zokukhanya. Ukudlulisa ukushisa kude nama-chips, lawa ma-LED adinga i-PCB ewugqinsi.

Ngokuphambene nama-LED angu-3528, ama-5050 angase axube ama-chips amathathu ahlukene ngaphakathi kwesiqukathi ukuze akhiqize izigidi zezinhlanganisela zemibala ezingaba khona.

Ama-LED angu-3528 SMD anokuminyana okuphezulu angcono ekusetshenzisweni kombala owodwa, nakuba i-chip engu-5050 ingasetshenziswa ezinhlelweni ezidinga umbala owodwa kuphela.

Ihlolwa kanjani i-chip ye-UVC LED?

Isilinganiso sesici se-chip sika-I-V siqondile. Umhloli angasetshenziswa ukukukala ngokuqondile, noma isistimu yokuhlola eqondile eyenziwe ngokuhlinzekwa kwamanje okuqhubekayo kanye ne-voltmeter ingakhiwa. Abakhiqizi bokupakishwa kwe-LED bangasebenzisa i-voltage kanye nesistimu yokuhlola yamanje ye-Leeds photoelectric tester thorough tester, umthombo wamandla ocindezelweyo, bese bedweba ijika lesici le-I-V ngemva kokulinganisa i-voltage ehambisanayo ngokushintsha amandla amanje. Uhlelo lwakhiwe umthombo wamandla wedrayivu yangaphandle, i-LED light stress - strain tester, kanye nemitha ye-UV irradiance ejulile ye-EVERFINE U-20.

Ithuluzi lokushintsha i-engeli nebanga lifakiwe nesihloli sokusabalalisa ukukhanya kokukhanya kwe-LED, okwenza izilinganiso zibe lula.

I-LED light stress - isihloli se-strain sinedivayisi yokulungisa i-engeli nebanga, okwenza kube lula ukukala ukushuba kwemisebe kuma-engeli namabanga ahlukahlukene. Ukunikezwa kwamandla okuzinzile kwe-DC kunika amandla isistimu yokuhlola. Ukulungiswa kokuphumayo kokuphakelwa kwamandla kuvumela ukulawula kahle okokufaka kwamanje ku-LED.

Ama-LED chips angamela ukuguqula ugesi ube ukukhanya, futhi alawula umbala nekhwalithi yokukhanya okukhishwa kwe-LED. Yize kunabakhiqizi abaningi be-chip ye-LED emhlabeni wonke, kunomehluko omkhulu kwikhwalithi ye-chip ye-LED nokusebenza emakethe. Abenzi abaphezulu bama-chips e-LED batholakala e-China naseNingizimu Korea, kanye nezinkampani ezaziwayo e-United States nase-Japan.

Kungani kubalulekile ukukhetha izinto ze-LED ezisebenzisa ama-chips e-premium e-LED?  

Ngisho naphakathi kwama-chips e-LED asuka kunqwaba efanayo, kunomehluko ojwayelekile embaleni okhanyayo, ukukhanya, namandla kagesi phakathi nenqubo yokukhiqiza.

imigqomo" ngokwezimfanelo zabo. "Imigqomo" emincane kakhulu isetshenziselwa ama-chips e-LED ebanga eliphakeme kakhulu, okuqinisekisa ukuthi noma yiziphi izinguquko phakathi kwama-chips zincane kangangokuthi azibonakali. Kungakhathaliseki ukuthi usayizi wephrojekthi yakho yokukhanyisa i-LED, ungaqinisekisa ukusebenza kwe-LED njalo ngokukhetha ukulungiswa kwe-LED usebenzisa ama-chips ekhwalithi ephezulu e-LED.

Ungathenga kuphi ama-chips e-LED ekhwalithi ephezulu

Enye ephezulu Abakhiqizi be-uv  I-UV LED eChina i-Tianhui Electronics . Iminikelo yethu ihlanganisa ucwaningo nokuthuthukiswa kwesayensi, usizo lobuchwepheshe, kanye nesevisi yokudizayina Ukuthengiswa kwempahla kagesi 5. Ukufaka isibani se-UV ebhodini le-microcircuit. Singababanye abahamba phambili ngokweqisa e-Asia Imodeli ye-uv  ukuhlinzeka abathengi nge Isixazululo se-UV LED , izimpahla, namasevisi. Iminikelo yethu ihlanganisa i-UVA, i-UVB, ne-UVC kusukela kumaza wamaza amafushane kuya kumade kanye nemininingwane egcwele ye-UV LED esukela kokuphansi kuye emandleni aphezulu. Izidingo zamakhasimende yizona eziza kuqala kithi, futhi sizinikele ekubanikezeni isevisi evelele.
