Kunezinhlobo eziningi ezahlukene zemichilo ye-LED, ngayinye inezici zayo ezihlukile. Kulesi sihloko, sizoxoxa ngomugqa ogqamile we-LED emakethe.
Imuphi umucu we-LED ogqame kakhulu emakethe?
Ziyimicu ye-LED esebenza kahle kakhulu ye-SMD2835, ama-9LED ngokusikwa ngakunye, i-CRI>80, ngaphezu kuka-220LM/W, futhi amandla angadlula u-20W/M. Basebenzisa ukukhanya okuphezulu kwe-SMD2835 LED enosayizi omkhulu we-chip, i-3OZ yethusi ehlanzekile noma i-4OZ PCB.
Ukukhanya kwemichilo ye-LED kunqunywa ama-lumens.
I-Lumens = Okukhipha Okukhanyayo. Ngamagama alula, ama-Lumen (achazwa ngo-lm) ayisilinganiso senani lokukhanya okubonakalayo (esweni lomuntu) esivela esibani noma emthonjeni wokukhanya.
Izinto ezithinta ukukhanya kwemigqa ye-LED.
Izici ezimbili eziyinhloko zithinta ukukhanya kwemigqa ye-LED, ukusebenza kahle kokukhanya (lm/w) namandla (w/m). Njengoba sazi, ama-lumens omugqa we-LED alingana nokusebenza okukhanyayo okuphindwe ngamandla.
Ukukhanya Okusebenzayo
Ukusebenza kahle okukhanyayo isilinganiso sokuthi umthombo wokukhanya ukukhiqiza kahle kangakanani ukukhanya okubonakalayo. Kuyisilinganiso sokuguquguquka okukhanyayo kumandla, kukalwa ngamalumens ngewathi ngayinye (lm/w).
Izinto eziyinhloko ezithinta ukusebenza kahle kokukhanya yilezi ezilandelayo:
Usayizi we-chip we-LED
Ubuhlalu besibani se-LED yizingxenye ezikhipha ukukhanya, futhi izingxenye zabo eziyinhloko ama-chips, abakaki, nezintambo zegolide ezixhuma ama-chips nabakaki. Ingxenye engakhipha ukukhanya yi-chip. Ngakho-ke, ubukhulu be-chip bunquma ukusebenza kahle okukhanyayo kobuhlalu besibani se-LED. Uma usayizi we-chip umkhulu, uphakamisa ukusebenza kahle okukhanyayo kobuhlalu besibani se-LED. Kukhona ezinye izimboni zobuhlalu belambu emakethe. Ukuthuthukisa ukusebenza kahle okukhanyayo nokuthembeka kokukhanya okumhlophe kwe-SMD2835 LED ubuhlalu besibani, ama-chips amabili apakishwa kubakaki.
I-CRI
A inkomba yokunikeza umbala (CRI) isilinganiso somthamo wekhono lomthombo wokukhanya ukuveza imibala yezinto ezihlukahlukene ngokwethembeka uma kuqhathaniswa nomthombo wokukhanya wemvelo noma ojwayelekile.
I-CRI nayo iyisici esibalulekile ekunqumeni ukusebenza kahle okukhanyayo. Lapho i-CRI iphakeme, iyancipha ukusebenza kahle okukhanyayo.
Uma ufuna ukwazi imininingwane eyengeziwe, sicela ufunde Kungani i-CRI ephezulu ingasebenzi kahle ngaso sonke isikhathi.
I-CCT
Izinga lokushisa lombala (I-Correlated Color Temperature, noma i-CCT, ku-lighting tech jargon) empeleni iyigeji yokuthi umbala wokukhanya ophuma emthonjeni wokukhanya uvela ophuzi noma oluhlaza okwesibhakabhaka kanjani. Ikalwa kuyunithi ye-Kelvin futhi ivame ukutholakala phakathi kuka-2200 Kelvin degrees kanye no-6500 Kelvin degrees.
Ngokuvamile, i-CCT ephakeme kakhulu, iphakamisa ukusebenza kahle kokukhanya. Isibonelo, ngobuhlalu belambu le-LED elifanayo, ukusebenza kahle okukhanyayo kwe-6000K kungaphezulu kwalokho kuka-2700K.
Power
Uma ukusebenza kahle kokukhanya kuqinisekile, amandla aphezulu, i-lumen iyanda.
Ngakho-ke, uma sidinga ukukhanya okuphezulu, sidinga ukwandisa amandla.
Amandla omugqa we-LED athinteka kakhulu yizici ezilandelayo:
Ubuningi be-LED
Ubuhlalu belambu elilodwa le-LED linomkhawulo wamanje omkhulu. Isibonelo, i-SMD2835 evamile ingu-60mA, kanti i-SMD3528 ingu-20mA. Uma sifuna ukwandisa amandla e-strip ye-LED, sidinga ukwandisa ukuminyana kobuhlalu besibani se-LED.
Qaphela: Ukuze kongiwe izindleko, abanye abakhiqizi baklama imichilo ye-LED esebenzisa umsinga odlula isilinganiso esiphezulu samanje sobuhlalu besibani se-LED. Kodwa-ke, lapho lo mugqa we-LED usebenza, ukushisa kubi kakhulu, futhi ngemva kwesikhathi esithile, ukukhanya kuzoba phansi futhi kube phansi.
PCB
I-PCB ingenye ingxenye eyinhloko. Umsebenzi wayo oyinhloko ukuxhuma izingxenye ezifana nobuhlalu besibani se-LED nama-resistors.
Ingxenye eyinhloko ye-PCB iyithusi, futhi inani lethusi linquma ukuqhutshwa kwe-PCB. Ithusi eliwugqinsi, elibanzi lingadlula lamanje futhi likhiphe ukushisa okuncane.
Ama-PCB angasiza futhi ukuqeda ukushisa ngokushesha. Ukushisa kubalulekile empilweni ye-LED, futhi ukushisa okuphezulu kunganciphisa impilo ye-LED.
Ngakho-ke, ukuze sandise amandla omugqa we-LED, kufanele sikhethe i-PCB enethusi elihlanzekile elikhudlwana nelibanzi.
Iphrofayili ye-Aluminium
Amandla engeziwe asho ukushisa okwengeziwe. Kodwa-ke, uma ukushisa kungachithwa ngesikhathi, kuzonciphisa impilo ye-LED. Enye yezindlela ezivame kakhulu zokusiza ukususa ukushisa ngokushesha ukunamathisela imichilo ye-LED kuyo amaphrofayili e-aluminium.
Imibuzo Evame Ukubuzwa
Isiphetho
Ukuze uthole ukukhanya okuphezulu kwe-LED strip, singacabangela izici ezimbili zokuthuthukisa ukusebenza kahle okukhanyayo futhi andise amandla.
