Ndi ma wati angati pa mita imodzi ya mzere wowala wa chisononkho?

Ndi ma wati angati pa mita imodzi ya mzere wowala wa chisononkho?

Pakati pa 5 watts ndi 20 watts

Mphamvu ya mita imodzi ya chingwe chowunikira cha COB nthawi zambiri imakhala pakati pa 5 watts ndi 20 watts, ndipo mphamvu yeniyeniyo imadalira magawo apangidwe a chingwe chowunikira.

Mphamvu ya mizere yowunikira ya COB imatsimikiziridwa ndi kapangidwe kake, ndipo mphamvu ya mizere yowala ya COB yosiyana ikhoza kukhala yosiyana. Nthawi zambiri, mphamvu ya mita imodzi ya zingwe zowunikira za COB nthawi zambiri imakhala pakati pa 5 watts ndi 20 watts, ndipo mitundu ina yakhazikitsa mizere yowunikira ya COB yamphamvu kwambiri. Chifukwa chake, kuyatsa kwa chingwe chowunikira cha COB cha mita imodzi kumayenera kutengera mawonekedwe a mzere wowunikira.

Zinthu 4 zazikulu zomwe zimakhudza mphamvu ya mizere yowunikira ya COB

Zifukwa zazikulu zomwe zimakhudza mphamvu ya zingwe za nyali za COB ndi izi:

Nambala ndi kukula kwa mikanda ya nyali ya COB: Mphamvu ndi kuwala kwa zingwe za nyali za COB zimagwirizana ndi kuchuluka ndi kukula kwa mikanda ya nyali ya COB. Nthawi zambiri, mikanda ya nyale ya COB ikachulukirachulukira komanso kukula kwa chingwe cha nyale cha COB, mphamvu ndi kuwala zimakwera.

Kutentha kwapang'onopang'ono: Kuwala kowala kwa mikanda ya nyali ya COB kumachepa kutentha kumawonjezeka. Chifukwa chake, kutulutsa kutentha kwa mizere yowunikira ya COB kumakhudza mphamvu ndi kuwala kwake. Zingwe zowala za COB zokhala ndi kutentha kwabwino zimatha kukhalabe ndi mphamvu zokhazikika komanso zowala.

Kuyendetsa pakali pano: Mphamvu yayikulu komanso kuwala kwa mikanda ya nyale ya COB kumadalira pakuyenda kwawo kwakukulu. Mphamvu ndi kuwala kwa mizere yowunikira ya COB imagwirizana ndi kuyendetsa komwe ali nako.

Makulidwe a bolodi la PCB ndi mtundu wake: Gulu la PCB ndiye gawo lapansi la chingwe chowunikira cha COB ndipo chidzakhudzanso mphamvu ndi kuwala kwake. Kuchuluka kwa makulidwe ndi mtundu wa bolodi la PCB, kumapangitsanso kufalikira kwapano ndi kutentha kwapang'onopang'ono, ndikukweza mphamvu ndi kuwala kwa mzere wowala.

Mphamvu ndi kuwala kwa zingwe za nyali za COB zimadalira kuphatikizika kwa zinthu zingapo monga kuchuluka ndi kukula kwa mikanda ya nyali ya COB, kutentha kwa kutentha, kuyendetsa galimoto, komanso makulidwe ndi mtundu wa bolodi la PCB.

Momwe mungawerengere mphamvu ya COB light strip?

Kuwerengera mphamvu kwa mizere yowunikira ya COB kuyenera kuganizira izi:

Mphamvu yamagetsi ndi yapano pa chipangizo chilichonse cha LED: Nthawi zambiri pamakhala tchipisi tambiri ta LED pa chingwe chowunikira cha COB. Magetsi ndi zamakono za chipangizo chilichonse cha LED ndizosiyana, choncho ziyenera kuwerengedwa padera, ndikuwonjezeredwa palimodzi kuti zipeze mphamvu ya mzere wonse wa kuwala.

Nambala ndi kakonzedwe ka tchipisi ta LED: Nambala ndi dongosolo la tchipisi ta LED pa chingwe cha nyali ya COB zidzakhudzanso kuwerengera mphamvu. Nthawi zambiri, tchipisi ta LED timakhalanso ndi mphamvu zambiri.

Mphamvu yovotera yamagetsi oyendetsa: Mphamvu yoyendetsera magetsi yomwe imagwiritsidwa ntchito ndi chingwe chowunikira cha COB idzakhudzanso kuwerengera mphamvu, chifukwa mphamvu yovotera yamagetsi ndi yayikulu kuposa mphamvu ya chingwe chowunikira.

Kutengera zomwe zili pamwambapa, njira yowerengera mphamvu ya COB light strip ndi motere:

Mphamvu = ∑ (Voltge ya chipangizo chilichonse cha LED × Panopa pa chipangizo chilichonse cha LED) × Chiwerengero cha tchipisi ta LED × Kukonzekera kokwanira

Mwa iwo, coefficient yokonzekera nthawi zambiri imakhala 1, zomwe zikutanthauza kuti tchipisi ta LED timapangidwa motsatira mzere.

Zindikirani kuti kuwerengera mphamvu kwa chingwe chowunikira cha COB chitha kugwiritsidwa ntchito ngati chofotokozera. Pogwiritsidwa ntchito kwenikweni, zinthu monga kutentha kwa kutentha kwa mzere wowunikira komanso kufanana kwa magetsi oyendetsa galimoto ziyenera kuganiziridwa kuti zitsimikizire chitetezo ndi ntchito yokhazikika ya mzere wowala.
