Mangaki amawathi ngemitha ngayinye yomugqa wokukhanya wesikhwebu?

Phakathi kwama-watts angu-5 nama-watts angu-20

Amandla imitha eyodwa yomugqa wokukhanya we-COB ngokuvamile aphakathi kwama-watts angu-5 nama-watts angu-20, futhi amandla athile ancike kumingcele yedizayini yomugqa wokukhanya.

Amandla emicu yokukhanya ye-COB anqunywa ukwakheka kwawo okukhethekile, futhi amandla emicu yokukhanya ye-COB ehlukene angase ahluke. Ngokuvamile, amandla emitha eyodwa yezintambo zokukhanya ze-COB ngokuvamile aphakathi kwama-watts angu-5 nama-watts angu-20, futhi ezinye izinhlobo zethule imichilo yokukhanya ye-COB enamandla amakhulu. Ngakho-ke, amanzi omugqa wokukhanya we-COB oyimitha elilodwa udinga ukususelwa kumingcele yedizayini yomugqa wokukhanya.

Izinto ezi-4 ezinkulu ezithinta amandla emicu yokukhanya ye-COB

Izizathu eziyinhloko ezithinta amandla ezinhlamvu zezibani ze-COB zimi kanje:

Inombolo kanye nosayizi wobuhlalu besibani se-COB: Amandla nokukhanya kwezibani ze-COB kuhlobene nenombolo nosayizi wobuhlalu besibani se-COB. Ngokuvamile, lapho ubuhlalu besibani se-COB bukhula futhi ubukhulu bomugqa wesibani se-COB bukhudlwana, amandla nokukhanya akhuphuka.

Umthelela wokukhipha ukushisa: Ukusebenza kahle okukhanyayo kobuhlalu besibani se-COB kuncipha njengoba izinga lokushisa likhuphuka. Ngakho-ke, umphumela wokukhipha ukushisa wezintambo zokukhanya ze-COB uzothinta amandla nokukhanya kwawo. Imichilo yokukhanya ye-COB enokukhipha kahle ukushisa ingagcina amandla azinzile nokukhanya.

Ukushayela kwamanje: Amandla aphezulu nokukhanya kobuhlalu besibani se-COB kuncike kubuningi bamanje bokushayela. Amandla nokukhanya kwemichilo yokukhanya ye-COB kuhlobene namandla okushayela ahlonyiswe ngawo.

Ukujiya kwebhodi le-PCB nekhwalithi: Ibhodi le-PCB liwumugqa ongaphansi womugqa wokukhanya we-COB futhi lizophinde lithinte amandla nokukhanya kwalo. Okungcono ukushuba kanye nekhwalithi yebhodi le-PCB, kuba ngcono umphumela wamanje wokudlulisela nokushisa, futhi kuyanda amandla nokukhanya komugqa wokukhanya.

Amandla nokugqama kwezibani ze-COB kuncike emphumeleni ohlanganisiwe wezici eziningi njengenombolo nosayizi wobuhlalu besibani se-COB, umphumela wokukhipha ukushisa, ukushayela kwamanje, kanye nobukhulu nekhwalithi yebhodi le-PCB.

Ungabala kanjani amandla omugqa wokukhanya we-COB?

Ukubalwa kwamandla emichilo yokukhanya ye-COB kudinga ukucabangela izici ezilandelayo:

I-voltage kanye namanje kwe-chip ngayinye ye-LED: Ngokuvamile kukhona ama-chips e-LED amaningi emgqeni wokukhanya we-COB. I-voltage ne-current ye-chip ngayinye ye-LED ihlukile, ngakho-ke idinga ukubalwa ngokwehlukana, bese ihlanganiswa ndawonye ukuze kutholwe amandla awo wonke umugqa wokukhanya.

Inombolo nokuhlelwa kwama-chips e-LED: Inombolo nokuhlelwa kwama-chips e-LED emgqeni wesibani se-COB nakho kuzothinta ukubalwa kwamandla. Ngokuvamile, ama-chips e-LED amaningi, amandla amakhulu.

Amandla alinganiselwe okunikezwa kwamandla okushayela: Ukunikezwa kwamandla okushayela okusetshenziswa umugqa wokukhanya we-COB kuzophinde kuthinte ukubalwa kwamandla, ngoba amandla alinganiselwe okunikezwa kwamandla makhulu kunamandla omugqa wokukhanya.

Ngokusekelwe ezintweni ezingenhla, ifomula yokubala amandla yomugqa wokukhanya we-COB imi kanje:

Amandla = ∑ (I-Voltage ye-chip ngayinye ye-LED × Yamanje ye-chip ngayinye ye-LED) × Inombolo yama-LED chips × I-coefficient yokuhlela

Phakathi kwazo, i-coefficient yokuhlela ngokuvamile i-1, okusho ukuthi ama-chips e-LED ahlelwe ngendlela ehlelekile.

Kufanele kuqashelwe ukuthi ukubalwa kwamandla komugqa wokukhanya we-COB kungasetshenziswa kuphela njengereferensi. Ekusetshenzisweni kwangempela, izici ezifana nokunqanyulwa kokushisa komugqa wokukhanya kanye nokuhambisana kwamandla okushayela kudingeka kucatshangelwe ukuze kuqinisekiswe ukuphepha nokusebenza okuzinzile komugqa wokukhanya.
