Ni irihe tandukaniro riri hagati ya LED isanzwe na COB LED?

Ubwa mbere, ni ngombwa kugira ubumenyi bw'ibanze ku matara ya LED yo gushyiramo ibikoresho bya SMD. Nta gushidikanya ko ari yo matara ya LED akoreshwa cyane muri iki gihe. Bitewe n'uburyo akoreshwa mu buryo butandukanye, amatara ya LED ahujwe cyane n'amatara yacapwe kandi akoreshwa cyane ndetse no mu matara ya telefoni zigendanwa. Kimwe mu bintu by'ingenzi biranga amatara ya LED ya SMD ni umubare w'amasano n'amadirishya.

Kuri chip ya SMD LED, hashobora kubaho imiyoboro irenga ibiri. Hari diode eshatu zifite imiyoboro yigenga ku chip imwe. Buri circuit ifite anode na cathode, bigatuma habaho imiyoboro 2, 4, cyangwa 6 kuri chip.

Itandukaniro riri hagati ya COB LED na SMD LED
Kuri chip imwe ya SMD LED, hashobora kubaho diode zigera kuri eshatu, buri imwe ifite circuit yayo. Buri circuit muri chip nk'iyo ifite cathode na anode, bigatuma habaho connections 2, 4, cyangwa 6. Uduce twa COB dukunze kugira diode icyenda cyangwa zirenga. Byongeye kandi, utwuma twa COB dufite connections ebyiri na circuit imwe hatitawe ku mubare wa diode. Kubera iyi shusho yoroshye ya circuit, amatara ya COB LED afite imiterere isa n'iya panel, mu gihe amatara ya SMD LED asa n'itsinda ry'amatara mato.

Diode zitukura, icyatsi kibisi n'ubururu zishobora kubaho kuri chip ya SMD LED. Mu guhindura urwego rw'umusaruro wa diode eshatu, ushobora gukora ibara iryo ari ryo ryose. Ariko, ku itara rya COB LED, hari aho habaho contacts ebyiri gusa n'uruziga. Ntibishoboka gukora itara cyangwa itara rihindura amabara ukoresheje izo tara. Guhindura imiyoboro myinshi birakenewe kugira ngo ubone ingaruka zo guhindura amabara. Kubwibyo, amatara ya COB LED akora neza mu bikorwa bisaba ibara rimwe aho kuba amabara menshi.

Ubwiza bw'urumuri rwa chips za SMD buzwiho kuba hagati ya lumens 50 na 100 kuri watt. COB izwiho imikorere myiza y'ubushyuhe n'igipimo cya lumen kuri watt. Iyo chips za COB zifite nibura lumens 80 kuri watt, zishobora gutanga lumens nyinshi hamwe n'amashanyarazi make. Ishobora gukoreshwa mu bwoko butandukanye bw'amatara n'ibikoresho, nka flash ya telefoni igendanwa cyangwa kamera zifata amashusho.

Uretse ibi, utubumbe twa LED twa SMD dukenera isoko ntoya y'ingufu zo hanze, mu gihe utubumbe twa COB LED dukenera isoko nini y'ingufu zo hanze.
