Ibyiza nibibi bya COB bipakiye LED yerekana ecran nibibazo byiterambere

Hamwe niterambere ryiterambere ryikoranabuhanga rikomeye rya tekinoroji, COB (chip on board) tekinoroji yo gupakira yitabiriwe cyane.Kubera ko urumuri rwa COB rufite ibiranga ubushyuhe buke bw’umuriro, ubwinshi bw’umucyo mwinshi, urumuri ruke, hamwe n’ibyuka bihumanya ikirere, byakoreshejwe cyane mu bikoresho byo kumurika mu nzu no hanze, nk'itara ryo hasi, itara ryaka, itara rya fluorescent, itara ryo ku muhanda, n'itara n'amabuye y'agaciro.

Uru rupapuro rusobanura ibyiza byo gupakira COB ugereranije nububiko bwa LED busanzwe, cyane cyane mubintu bitandatu: ibyiza byubumenyi, inyungu zogukora neza, ibyiza byo kurwanya ubushyuhe bwumuriro, ibyiza byumucyo, ibyiza byo gukoresha, nibyiza byigiciro, kandi bisobanura ibibazo biriho byubuhanga bwa COB .

Itandukaniro hagati yububiko bwa COB nububiko bwa SMD

Ibyiza bya COB:

1. Igishushanyo niterambere: udafite diameter yumubiri umwe wamatara, birashobora kuba bito mubitekerezo;

2. Inzira ya tekiniki: gabanya ikiguzi cya bracket, koroshya inzira yo gukora, kugabanya ubushyuhe bwumuriro wa chip, no kugera kubipfunyika cyane;

3. Kwubaka injeniyeri: Uhereye kuruhande rwa porogaramu, COB LED yerekana module irashobora gutanga uburyo bworoshye kandi bwihuse bwo gukora kubakora ibicuruzwa byerekana.

4. Ibiranga ibicuruzwa:

. , ubwikorezi nubwubatsi kubakiriya.

.Ubuso bwamatara yazamuye hejuru yubuso, bworoshye, bukomeye, butarwanya ingaruka kandi butarinda kwambara.

.Umuringa wumuringa wububiko bwa PCB ufite ibyangombwa bisabwa.Hiyongereyeho uburyo bwo kubika zahabu, ntibishobora gutera urumuri rukomeye.Kubwibyo, hano hari amatara yapfuye, yongerera cyane ubuzima bwa LED yerekana.

(5) Kwambara birwanya, byoroshye koza: hejuru yoroshye kandi ikomeye, irwanya ingaruka kandi irwanya kwambara;Nta masike ihari, kandi umukungugu urashobora kwezwa n'amazi cyangwa igitambaro.

.Irashobora guhuza ibihe-byose byakazi bikora, hamwe nubushyuhe butandukanye kuva - 30℃kugeza - 80℃irashobora gukoreshwa mubisanzwe.

Intangiriro kubikorwa byo gupakira COB

1. Inyungu mu gukora neza

Igikorwa cyo gutunganya ibicuruzwa bya COB mubusanzwe ni kimwe nubwa SMD gakondo, kandi imikorere yububiko bwa COB ahanini ni nkibya SMD bipakira muburyo bwo kugurisha insinga zikomeye.Kubijyanye no gutanga, gutandukana, gukwirakwiza urumuri no gupakira, imikorere yububiko bwa COB irarenze cyane iy'ibicuruzwa bya SMD.Amafaranga yo gukora no gukora ibicuruzwa bipfunyika bya SMD bingana na 15% yikiguzi cyibikoresho, mugihe amafaranga yo gukora no gukora ibicuruzwa bipfunyika COB bingana na 10% yikiguzi cyibikoresho.Hamwe no gupakira COB, amafaranga yumurimo nogukora arashobora kuzigama 5%.

2. Ibyiza byo kurwanya ubushyuhe buke

Sisitemu irwanya ubushyuhe bwa gakondo ya SMD ipakira ni: chip - ikomeye ya kirisiti ifata - kugurisha hamwe - kugurisha paste - umuringa wumuringa - kubika insina - aluminium.Kurwanya ubushyuhe bwa sisitemu yo gupakira COB ni: chip - ibyuma bikomeye bya kirisiti - aluminium.Sisitemu irwanya ubushyuhe bwa pake ya COB iri hasi cyane ugereranije nububiko bwa SMD gakondo, butezimbere cyane ubuzima bwa LED.

3. Ibyiza byoroheje

Mubipfunyika gakondo bya SMD, ibikoresho byinshi byihariye byanditse kuri PCB kugirango bibe isoko yumucyo wibikoresho bya LED muburyo bwa patch.Ubu buryo bufite ibibazo byumucyo utagaragara, urumuri no kuzimu.Porogaramu ya COB ni paki ihuriweho, ni isoko yumucyo.Icyerekezo ni kinini kandi cyoroshye guhinduka, kugabanya gutakaza urumuri.

4. Ibyiza byo gusaba

Inkomoko yumucyo wa COB ikuraho inzira yo gushiraho no kugarura ibicuruzwa kurangiza gusaba, bigabanya cyane umusaruro nogukora kurangiza gusaba, kandi ikiza ibikoresho bijyanye.Ibiciro byumusaruro nibikoresho byo gukora biri hasi, kandi umusaruro urenze.

5. Ibyiza byigiciro

Hamwe nisoko yumucyo wa COB, ikiguzi cyitara ryose 1600lm gahunda irashobora kugabanukaho 24.44%, igiciro cyamatara yose 1800lm irashobora kugabanukaho 29%, naho ikiguzi cyamatara yose 2000lm gishobora kugabanuka 32.37%

Gukoresha urumuri rwa COB rufite inyungu eshanu kurenza gukoresha SMD yamashanyarazi yamashanyarazi, afite ibyiza byinshi mumasoko yumucyo utanga umusaruro, kurwanya ubushyuhe, ubwiza bwumucyo, gukoresha nibiciro.Igiciro cyuzuye kirashobora kugabanukaho hafi 25%, kandi igikoresho kiroroshye kandi cyoroshye gukoresha, kandi inzira iroroshye.

Ibibazo bya tekinike ya COB muri iki gihe:

Kugeza ubu, gukusanya inganda za COB hamwe nibisobanuro birambuye bigomba kunozwa, kandi binahura nibibazo bya tekiniki.

1. Igipimo cyambere cyo gupakira ni gito, ikinyuranyo ni gito, kandi ikiguzi cyo kubungabunga ni kinini;

2. Ibara ryacyo ryerekana uburinganire buri munsi cyane ugereranije niyerekanwa inyuma ya chip ya SMD hamwe nurumuri no gutandukanya amabara.

3. Ipaki isanzwe ya COB iracyakoresha chip isanzwe, isaba inzira ikomeye ya kristu na wire.Kubwibyo, hariho ibibazo byinshi murwego rwo guhuza insinga, kandi ingorane zinzira zirahwanye neza na padi.

4. Igiciro cyo gukora: kubera igipimo kinini gifite inenge, igiciro cyo gukora kiri hejuru cyane ugereranije na SMD umwanya muto.

Ukurikije impamvu zavuzwe haruguru, nubwo ikoranabuhanga rya COB rigezweho ryateye intambwe igaragara mu kwerekana, ntabwo bivuze ko ikoranabuhanga rya SMD ryakuyeho burundu kugabanuka.Mu murima aho intera irenze 1.0mm, tekinoroji yo gupakira ya SMD, hamwe nibikorwa byayo bikuze kandi bihamye, imikorere yisoko ryinshi hamwe na sisitemu yo gutanga no gutunganya neza, iracyafite uruhare runini, kandi nayo ihitamo neza icyerekezo kubakoresha nisoko.

Hamwe nogutezimbere buhoro buhoro ikoranabuhanga ryibicuruzwa bya COB hamwe niterambere ryiyongera ryibisabwa ku isoko, uburyo bunini bwo gukoresha tekinoroji yo gupakira COB buzagaragaza ibyiza bya tekinike nagaciro kayo hagati ya 0.5mm ~ 1.0mm.Gutira ijambo mu nganda, “Gupakira COB bigenewe 1.0mm no munsi”.

MPLED irashobora kuguha LED yerekana uburyo bwo gupakira COB, hamwe na ST Pro urukurikirane rwibicuruzwa rushobora gutanga ibisubizo nkibi. LED yerekana ecran yujujwe nuburyo bwo gupakira cob ifite intera ntoya, isobanutse kandi yoroheje yerekana ishusho.Chip itanga urumuri ipakirwa ku kibaho cya PCB, kandi ubushyuhe bukwirakwizwa mu kibaho.Agaciro ko kurwanya ubushyuhe ni nto, kandi gukwirakwiza ubushyuhe birakomeye.Itara ryo hejuru risohora urumuri.Kugaragara neza.
