Taba ea pele, hoa hlokahala ho ba le kutloisiso ea mantlha ea li-LED tsa lisebelisoa tsa holim'a metsi (SMD). Ha ho pelaelo hore ke li-LED tse sebelisoang khafetsa hajoale. Ka lebaka la ho feto-fetoha ha tsona, li-chips tsa LED li kopantsoe ka thata ho liboto tsa potoloho tse hatisitsoeng mme li sebelisoa haholo le mabone a tsebiso ea smartphone. E 'ngoe ea likarolo tse hlokomelehang tsa li-chips tsa SMD LED ke palo ea likhokahano le diode.
Ho chip ea LED ea SMD, ho ka ba le likhokahano tse fetang tse peli. Ho fihlela ho diode tse tharo tse nang le li-circuits tse ikemetseng li ka fumanoa ho chip e le 'ngoe. Potoloho e 'ngoe le e' ngoe e na le anode le cathode, e hlahisang likhokahano tse 2, 4, kapa tse 6 ho chip.
Phapang lipakeng tsa COB LEDs le SMD LEDs
Ho chip e le 'ngoe ea SMD LED, ho ka ba le diode tse ka bang tharo, e' ngoe le e 'ngoe e na le potoloho ea eona. Potoloho e 'ngoe le e' ngoe ka har'a chip e joalo e na le cathode le anode, e hlahisang likhokahano tse 2, 4, kapa tse 6. Li-chips tsa COB hangata li na le diode tse robong kapa ho feta. Ntle le moo, li-chips tsa COB li na le likhokahano tse peli le potoloho e le 'ngoe ho sa tsotelehe palo ea diode. Ka lebaka la moralo ona o bonolo oa potoloho, mabone a COB LED a na le ponahalo e kang ea phanele, ha mabone a SMD LED a shebahala joaloka sehlopha sa mabone a manyenyane.
Li-diode tse khubelu, tse tala le tse putsoa li ka ba teng ho chip ea SMD LED. Ka ho fetola maemo a tlhahiso ea li-diode tse tharo, o ka hlahisa hue leha e le efe. Leha ho le joalo, ka lebone la COB LED, ho na le mabitso a mabeli feela le potoloho. Ho ke ke ha khoneha ho etsa lebone le fetolang mebala kapa tleloubu ka tsona. Litokiso tsa likanale tse ngata lia hlokahala ho fumana phello ea ho fetola mebala. Ka hona, mabone a COB LED a sebetsa hantle lits'ebetsong tse hlokang 'mala o le mong ho e-na le mebala e mengata.
Mefuta e khanyang ea li-chips tsa SMD e tsejoa hantle e le lumens tse 50 ho isa ho tse 100 ka watt. COB e tsebahala haholo ka ts'ebetso ea eona e phahameng ea mocheso le karo-karolelano ea lumen ka watt. Haeba chip ea COB e na le bonyane lumens tse 80 ka watt e le 'ngoe, e ka ntša lumens e ngata ka motlakase o fokolang. E ka sebelisoa mefuteng e mengata e fapaneng ea li-bulbs le lisebelisoa, joalo ka foleshe ea mehala ea cellular kapa likhamera tsa ho supa le ho thunya.
Ntle le sena, li-chips tsa SMD LED li hloka mohloli o monyane oa matla a kantle, ha li-chips tsa COB LED li hloka mohloli o moholo oa matla a kantle.
