Kodi pali kusiyana kotani pakati pa LED wamba ndi COB LED?

Kuti muyambe, ndikofunikira kumvetsetsa ma LED a Surface-Mounted Device (SMD).Mosakayikira ndi ma LED omwe amagwiritsidwa ntchito pafupipafupi pakali pano.Chifukwa cha kusinthasintha kwake, ngakhale mu kuwala kwa chidziwitso cha foni yamakono, chipangizo cha LED chimasakanikirana mwamphamvu ndi bolodi losindikizidwa ndipo chimagwiritsidwa ntchito kwambiri.Chimodzi mwazinthu zodziwika bwino za tchipisi ta SMD LED ndi kuchuluka kwa kulumikizana ndi ma diode.
Pa tchipisi ta SMD LED, ndizotheka kukhala ndi zolumikizira zopitilira ziwiri.Mpaka ma diode atatu okhala ndi mabwalo amodzi atha kupezeka pa chip chimodzi.Dera lililonse limakhala ndi anode ndi cathode, zomwe zimapangitsa kuti pakhale kulumikizana kwa 2, 4, kapena 6 pa chip.

Kusiyana pakati pa COB LEDs ndi SMD LEDs.

Pa chipangizo chimodzi cha SMD LED, pakhoza kukhala ma diode atatu, iliyonse ili ndi dera lake.Chigawo chilichonse mu chip chamtunduwu chimakhala ndi cathode imodzi ndi anode imodzi, zomwe zimapangitsa kulumikizana kwa 2, 4, kapena 6.Tchipisi za COB nthawi zambiri zimakhala ndi ma diode asanu ndi anayi kapena kupitilira apo.Kuphatikiza apo, tchipisi ta COB zili ndi zolumikizira ziwiri ndi dera limodzi mosasamala kanthu za kuchuluka kwa ma diode.Chifukwa cha mawonekedwe osavuta ozungulirawa, nyali za COB LED zimakhala ndi mawonekedwe ngati gulu, pomwe magetsi a SMD LED amawoneka ngati gulu la tiuni tating'onoting'ono.

Diode yofiira, yobiriwira, ndi yabuluu ikhoza kupezeka pa chipangizo cha SMD LED.Posintha kuchuluka kwa ma diode atatu, mutha kupanga mtundu uliwonse.Pamagetsi a COB LED, komabe, pali zolumikizira ziwiri zokha ndi mayendedwe amodzi.Ndizosatheka kuzigwiritsa ntchito popanga magetsi osintha mitundu kapena mababu.Zosintha zingapo zimafunikira kuti mawonekedwe asinthe mtundu.Zotsatira zake, nyali za COB LED zimagwira ntchito bwino pamapulogalamu omwe amafunikira mtundu umodzi koma osati mitundu ingapo.

Tchipisi za SMD zili ndi kuwala kodziwika bwino kwa 50 mpaka 100 lumens pa watt.Kutentha kwakukulu kwa kutentha ndi ma lumens pa chiŵerengero cha watt cha COB amadziwika bwino.Tchipisi za COB zimatha kutulutsa ma lumens ochulukirapo okhala ndi magetsi ochepa ngati ali ndi ma lumens 80 pa watt iliyonse.Itha kupezeka mumitundu yosiyanasiyana ya mababu ndi zida, monga kung'anima pa foni yanu kapena makamera akuloza-ndi-kuwombera.

Gwero lamphamvu lakunja limafunikira tchipisi ta SMD LED, pomwe gwero lalikulu lakunja limafunikira tchipisi ta COB LED.
