Zingaphi iiwathi ezixabisa intambo yesibane sesikhwebu ngemitha nganye?

Amandla emicu yokukhanya ye-COB agqitywe kuyilo lwayo oluthile, kwaye amandla emicu yokukhanya ye-COB eyahlukeneyo anokwahluka. Ngokubanzi, amandla emitha enye yezibane zokukhanya ze-COB aphakathi kwe-5 watts kunye ne-20 watts, kwaye ezinye iibhrendi ziye zazisa imicu yokukhanya ye-COB yamandla aphezulu. Ke ngoko, umbane wemitha enye ye-COB yokukhanya kufuneka usekwe kwiiparamitha zoyilo lomgca wokukhanya.

Izinto ezi-4 eziphambili ezichaphazela amandla emicu yokukhanya ye-COB

Ezona zizathu ziphambili ezichaphazela amandla eentambo zezibane ze-COB zezi zilandelayo:

Inani kunye nobukhulu bamaso esibane se-COB: Amandla kunye nokuqaqamba kwamaso esibane e-COB anxulumene nenani kunye nobukhulu bamaso wesibane se-COB. Ngokubanzi, okukhona amaso wesibane se-COB ethe chatha kunye nobukhulu besayizi kumtya wesibane we-COB, kokukhona aphakama amandla kunye nokuqaqamba.

Isiphumo sokutshatyalaliswa kobushushu: Ukusebenza okukhanyayo kwamaso esibane se-COB kuncipha njengoko ubushushu bunyuka. Ngoko ke, umphumo wokutshatyalaliswa kobushushu bemichilo yokukhanya ye-COB iya kuchaphazela amandla kunye nokukhanya kwayo. Imichilo yokukhanya ye-COB eneziphumo ezilungileyo zokutshatyalaliswa kobushushu inokugcina amandla azinzileyo kunye nokukhanya.

Ukuqhuba kwangoku: Awona mandla aphezulu kunye nokuqaqamba kweentsimbi zezibane ze-COB zixhomekeke kubuninzi bazo bangoku bokuqhuba. Amandla kunye nokuqaqamba kwemichilo yokukhanya ye-COB inxulumene nomqhubi wangoku abaxhotyiswe ngawo.

Ubukhulu bebhodi ye-PCB kunye nomgangatho: Ibhodi ye-PCB yi-substrate ye-COB strip yokukhanya kwaye iya kuchaphazela amandla kunye nokuqaqamba kwayo. Okukhona ubungqingqwa kunye nomgangatho webhodi yePCB, kokukhona ukuhanjiswa kwangoku kunye nesiphumo sokutshabalalisa ubushushu, kwaye kokukhona amandla aphezulu kunye nokuqaqamba komcu wokukhanya.

Amandla kunye nokuqaqamba kwezibane zezibane ze-COB zixhomekeke kwimpembelelo edibeneyo yezinto ezininzi ezifana nenani kunye nobukhulu beentsimbi zesibane se-COB, umphumo wokutshatyalaliswa kobushushu, ukuqhuba ngoku, kunye nobukhulu kunye nomgangatho webhodi ye-PCB.

Indlela yokubala amandla omgca wokukhanya we-COB?

Ukubalwa kwamandla emicu yokukhanya ye-COB kufuneka kuthathelwe ingqalelo ezi zinto zilandelayo:

I-voltage kunye nangoku kwi-chip nganye ye-LED: Ngokuqhelekileyo kukho iichips ezininzi ze-LED kumtya wokukhanya we-COB. I-voltage kunye ne-current ye-chip ye-LED nganye yahlukile, ngoko ke kufuneka ibalwe ngokwahlukileyo, kwaye idityaniswe kunye ukuze ifumane amandla omgca wokukhanya wonke.

Inani kunye nokucwangciswa kweetshiphusi ze-LED: Inani kunye nokulungiswa kwee-chips ze-LED kwisibane sesibane se-COB kuya kuchaphazela nokubalwa kwamandla. Ngokubanzi, okukhona iitshiphusi ze-LED ezininzi, amandla amakhulu.

Amandla alinganisiweyo onikezelo lwamandla okuqhuba: Unikezelo lwamandla okuqhuba olusetyenziswa ngumgca wokukhanya we-COB luya kuchaphazela nokubalwa kwamandla, kuba amandla alinganisiweyo ombane makhulu kunamandla omgca wokukhanya.
