Mu rwego rwo gupakira LED, COB igereranya Chip ku Kibaho, ikorana buhanga ryisoko ryumucyo rihuza ibyuma bya LED kuri substrate.LED yumucyo ukoresheje tekinoroji ya COB, chip ikwirakwiza ubushyuhe kuri substrate, hamwe nubucucike bukabije bwumuriro;chip yuzuye gahunda, ingufu za optique nyinshi;Ingano imwe yumubiri ni ntoya, nibyiza kumurima wubucuruzi hamwe nibisabwa bikomeye kubunini bwumucyo.Ugereranije na chip imwe imwe yamashanyarazi LED, paki ya COB chip nyinshi, guhuza ibicuruzwa byinshi, ubwinshi bwingufu nazo zatumye kwiyongera gukabije mubibazo byo gupakira.Birashobora kuvugwa ko isoko ya COB itanga urumuri kuruhande rumwe arirwo ruyobora urumuri rwo gucuruza, kurundi ruhande, nabwo ni ikamba ryikamba ryumurima wa LED.
Igikorwa nyamukuru cyumucyo ni urumuri, kugirango LED yongereho imipaka mbere yumucyo - kuzigama ingufu, bityo icyiciro cya mbere cyiterambere ryumucyo wa COB nacyo kiri mugukurikirana imikorere yumucyo, bitewe numucyo wa COB ukoresheje ibyuma -Ibikoresho byumuzunguruko cyangwa ceramic substrate yerekana ntabwo ari byiza nkibisate bikozwe mu ifeza, urumuri rwo hasi rwerekanwe hejuru yo kwinjiza urumuri hagati ya chip nyinshi Absorption, COB itanga isoko yumucyo iri munsi yibikoresho bya SMD birenga 30%, hanyuma nyuma kwinjiza indorerwamo ya aluminium substrate kugirango ikemure ikibazo cyo kugaragariza, ariko kwinjirira hamwe kwa chip nyinshi biracyatuma COB yumucyo utanga urumuri ruri munsi yibikoresho byihariye.Hamwe na chip hanze ya kwant ikora neza hamwe na fosifori yumucyo uhindura, imikorere yumucyo wa COB yamashanyarazi yageze mubikorwa byo kwemerera inganda "ahantu heza" - 100lm / W, ukuza kwahantu heza kuruta ibikoresho bya disikuru byakusanyije isoko yumucyo nyuma yimyaka 2-3.
Mubihe bitandukanye, guhindura ibara ryubushyuhe bwumucyo bishobora kuzana uburambe bwiza.Iyo nta mwanya uhari, biroroshye kumenya ihinduka ryubushyuhe bwamabara, mugihe cyose ibikoresho byubushyuhe bwo hejuru kandi buke byavanze kandi bigatandukana ukundi, ubushyuhe bwibara ryibara ryumuriro wa COB nabwo ni igitekerezo kimwe, chip in Inkomoko yumucyo ya COB igabanyijemo amatsinda abiri kandi igasiga ubwoko butandukanye hamwe nubushuhe bwa fosifori ivanze, kuburyo amatsinda abiri ya chip atanga ubushyuhe butandukanye bwamabara yumucyo wera.Hindura ingano yubu ya matsinda abiri ya chip, urashobora gutuma isoko yumucyo isohora ubushyuhe butandukanye bwamabara yumucyo wera.ingano ntoya yumucyo wa COB, nyuma yumucyo ntishobora kubona ubushyuhe bubiri butandukanye bwibara ryumucyo utanga urumuri, ariko ubuso bumwe butanga urumuri, ibyo bikaba aribyiza byumucyo wa COB, ariko ubunini buto, ariko nanone kuri umusaruro wamabara avanga COB isoko yumucyo yateje urujijo rwinshi.Nyuma yimyaka myinshi yubushakashatsi, kubintu bitandukanye bya chip, abantu bavumbuye kandi banonosora tekinoroji zitandukanye nko gucapa, gutera, hamwe na fluorescent chip kugirango bagere kumurongo uhamye hamwe nuburinganire bwubwoko butandukanye bwa fosifore mumasoko ya COB.
Ubwoko nigipimo cyubwoko bubiri bwamabara yubushyuhe bwa fluorescent glue mumabara-guhuza ibara rya COB yumucyo uteganijwe kugirango ugere kumurongo ngenderwaho ugaragara hamwe nubushobozi buhanitse mumurongo wose uhindura amabara.Igishushanyo cya 2 cyerekana umurongo wikurikiranya wubushyuhe bwo hejuru kandi buke bwubushyuhe bwamabara ahindura ibara rya COB itangwa na LightSense Semiconductor.Fosifore yiyi soko yumucyo itezimbere kuburyo indangagaciro yo gutanga amabara ishobora kugera kuri 95 kurwego rwubushyuhe ubwo aribwo bwose mugihe cyo guhindura ibara rya 3000-6000K, naho indangagaciro ya R9, ihangayikishije cyane, irenga 80.
Guhindura ubushyuhe bwamabara byagura umurima wa COB yumucyo utanga isoko, ariko ibara ryabonetse mugishushanyo cyamabara ya gamut irashobora kugaragara gusa murwego rwo hejuru kandi ruto rwo hasi rw'ubushyuhe bwo guhuza ibara kumurongo utudomo.Mu rwego rwo gucana amatara yubucuruzi, gukoresha ibara ritandukanye ryamabara yumucyo, urashobora kwerekana ingaruka ziboneka zamabara atandukanye yibicuruzwa kugirango uhuze ibyifuzo byabantu, uhereye kuriyi ngingo, gusa ubushyuhe bwibara ryibara cyangwa ntibihagije, muri uru rubanza, hamwe nubushobozi bwo guhindura ibara gamut ya COB yumucyo wavutse.
