Kodi Pali Kusiyana Kotani Pakati pa Normal LED ndi COB LED?

Choyamba, ndikofunikira kukhala ndi chidziwitso choyambira cha ma LED okwera pamwamba (SMD). Mosakayikira ndi ma LED omwe amagwiritsidwa ntchito kwambiri pakadali pano. Chifukwa cha kusinthasintha kwawo, tchipisi ta LED zimalumikizidwa mwamphamvu pama board ozungulira osindikizidwa ndipo zimagwiritsidwa ntchito kwambiri ngakhale mumagetsi azidziwitso a smartphone. Chimodzi mwazinthu zodziwika bwino za tchipisi ta SMD LED ndi kuchuluka kwa kulumikizana ndi ma diode.

Pa chipangizo cha SMD LED, pakhoza kukhala maulumikizidwe oposa awiri. Mpaka ma diode atatu okhala ndi mabwalo odziyimira pawokha atha kupezeka pa chip chimodzi. Dera lililonse limakhala ndi anode ndi cathode, zomwe zimapangitsa 2, 4, kapena 6 kulumikizana 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. Dera lililonse mu chip chotere limakhala ndi cathode ndi anode, 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 tili ndi zolumikizira ziwiri ndi dera limodzi mosasamala kuchuluka kwa ma diode. Chifukwa cha mawonekedwe osavuta ozungulirawa, nyali za COB LED zimakhala ndi mawonekedwe ngati mawonekedwe, pomwe magetsi a SMD LED amawoneka ngati gulu la magetsi ang'onoang'ono.

Ma diode ofiira, obiriwira, ndi abuluu amatha kukhalapo pa chipangizo cha SMD LED. Posintha milingo yotulutsa ma diode atatu, mutha kupanga mtundu uliwonse. Pa nyali ya COB LED, komabe, pali zolumikizira ziwiri zokha ndi dera. Sizingatheke kupanga nyali yosintha mtundu kapena babu ndi iwo. Kusintha kwamitundu yambiri kumafunika kuti mukhale ndi kusintha kwamitundu. Chifukwa chake, nyali za COB LED zimagwira ntchito bwino pamapulogalamu omwe amafunikira mtundu umodzi osati mitundu ingapo.

Kuwala kosiyanasiyana kwa tchipisi ta SMD kumadziwika bwino kuti ndi 50 mpaka 100 lumens pa watt. COB imadziwika bwino chifukwa cha kutentha kwambiri komanso kuchuluka kwa lumen pa watt. Ngati chipangizo cha COB chili ndi ma lumens 80 pa watt iliyonse, imatha kutulutsa ma lumens ambiri ndi magetsi ochepa. Itha kugwiritsidwa ntchito mumitundu yosiyanasiyana ya mababu ndi zida, monga kung'anima kwa foni yam'manja kapena makamera akuloza ndi kuwombera.

Kuphatikiza pa izi, tchipisi ta SMD LED timafunikira gwero lamphamvu lakunja, pomwe tchipisi ta COB LED timafunikira gwero lamphamvu lakunja.
