Ii-LED zinemisebenzi emininzi ebomini bethu. Zihlala ixesha elide kwaye zisebenza kakuhle. Ngoku, sizibona ezi LED phantse kuzo zonke iinkalo zobomi. Sikwahlulahlula kwakhona ii-LED zibe ziindidi ezimbini. Ezi zi-COB kunye ne-SMD. COB imele "Chip on Board". Kwaye i-SMD imele "isiXhobo esiFakelwe phezulu." 

Kwinqaku elingezantsi, siza kuzixubusha zombini. Siza kugxininisa ukuba zombini ezi LED zisebenza njani. Siza kuxubusha kwakhona iimpawu zabo kunye nokuveliswa. Siza kuthelekisa imisebenzi yabo.

Yintoni iCOB LED?

Yenye yenkqubela phambili entsha kwintsimi yee-LEDs. Ineenzuzo ezininzi ngaphezu kwezinye iindidi zee-LED.

Kukho ipateni ethile yeetshiphusi ze-LED ezifunekayo ukwenza izibane ze-COB. Ezi chips zipakishwe ngokusondeleyo kunye. Ngaphezu koko, inesiseko esenziwe ngesilicon carbide. Ke, sinechip ye-LED enokukhanya okugqwesileyo, okufanayo. Olu phawu luyenza igqibelele kubenzi befilimu. Ikwaluncedo kakhulu kubafoti.

Iitshiphu zeCOB zisebenzisa iidiode ezilithoba nangaphezulu. Abafowunelwa bayo kunye nesekethe ayixhomekeke kwinani leediode. Ngokwenyani, bahlala benesekethe enye kunye nabafowunelwa ababini. Inokuvelisa ukukhanya okuqaqambileyo xa iitshiphusi ezinkulu zifikelela kuma-250 ukukhanya. Ngaloo ndlela, ikwanika iphaneli inkalo ngenxa yoyilo lwesekethe yayo. Ezi aziloncedo kwizibane ezitshintsha umbala. Kungenxa yokuba le LED isebenzisa isekethe enye kuphela.

Ukuqonda okusisiseko kweTekhnoloji yeCOB:

Ngokuqinisekileyo, izibane zokwenyani ziya kuba yinxalenye ephambili yenkqubo yokukhanyisa i-COB LED. I-"Chip On Board" (COB) ibonisa ingcamango yokuba yonke iyunithi iqukethe iitshiphusi ezininzi ze-LED. Ezi chips zisecaleni komnye kumphezulu owenziwe ngeekeramics okanye isinyithi. Ii-LED zi-semiconductors ezikhupha iifotoni ezikhanyayo.

Kubekho uluvo lokuba ubungakanani bomgangatho kunye nexesha lebhetri lisebenza ngokuchaseneyo. Ukuba ukukhanya kungaphezulu, ixesha lebhetri liya kuba lifutshane. Itekhnoloji yeCOB iyitshintshile le nyaniso. Ii-COB ze-LED zinokuvelisa amanqanaba aphezulu okuqaqamba kunye nombane ophantsi.

Yintoni i-SMD LED?

I-SMD ibhekiselele kwiZixhobo eziFakelwe phezulu. I-SMD bubuchule bokuvelisa iisekethe zombane. Kulo buchule, iibhodi zeesekethe zinezixhobo ezifakwe kuzo. Ii-LED ze-SMD zincinci kakhulu ngobukhulu. Ayinazikhonkwane kunye nesikhokelo. Iphathwa ngcono ngoomatshini bendibano abazenzelayo kunomntu. Ngenxa yokungabikho kwe-hemispherical epoxy casing, i-SMD LED ikwabonelela ngokubanzi ukujonga ikona.

Ii-LED ze-SMD zinokuvelisa ukukhanya okuqaqambileyo kunye nokuncinci kwamanzi. Luhlobo lwe-LED oludibanisa imibala emithathu ephambili kwi-encapsulation enye.
