Ni irihe tandukaniro riri hagati ya Gob na COB?

Mu isi y'ikoranabuhanga rya LED, amagambo GOB na COB akunze kuganirwaho iyo hatekerezwa ku miterere ya LED ifite imikorere myiza ku bikorwa bitandukanye. Izi tekinoloji ebyiri zo gupakira LED ni ingenzi mu gutuma amatara ya LED aramba, akora neza kandi akarabagirana. Nyamara, nubwo GOB na COB byombi bivuga uburyo bwo gushyiraho utubumbe twa LED, biratandukanye cyane mu bijyanye n'imiterere, ikoreshwa, n'imikorere.

A. COB (Chip iri ku ikarita) ni iki?Ecran ya LED?

COB (Chip on Board) ni ikoranabuhanga rikoreshwa mu gushyira utubumbe twinshi twa LED ku kintu nta gupfunyika kwa gakondo. Muri COB LED isanzwe, utubumbe twinshi twa LED dufatanye n'ikibaho kimwe cyangwa ikintu kimwe, bigatuma habaho igishushanyo gito kandi cyiza. COB LED zitanga urumuri rwinshi mu gace gato, bigatuma ziba igisubizo cyiza cyo gukoresha amatara meza kandi akoreshwa mu bucuruzi.

1. Imiterere n'Ihame ry'Imikorere:

Muri COB LED, utubumbe twa LED ku giti cyatwo ni:

- Bishyizwe ku gice cy'ubutaka: Uduce twa LED dushyirwa ku gice cy'ibanze, ubusanzwe kikaba ari ibikoresho bifite ubushobozi bwo gutwara ubushyuhe bwiza, nka aluminiyumu, kugira ngo bifashe mu gusohora ubushyuhe neza.

- Ihujwe n'amashanyarazi: Uduce dufatanye n'urubaho, bigatuma amazi atembera neza kandi ingufu zigakwirakwizwa neza.

- Gucunga ubushyuhe: COB LED zikunze gukoresha ibyuma bya PCB (MCPCB), bifasha mu gukwirakwiza ubushyuhe no kongera igihe kirekire n'imikorere myiza ya LED.

Ikoranabuhanga rya COB rikunzwe cyane mu bikorwa byo kwerekana amashusho mu bucuruzi, nko kwamamaza imbere mu nzu, kwamamaza hanze, no mu nama, kuko rituma habaho urumuri rwinshi n'urumuri rwiza cyane.

(1) Ubushobozi bwo Kubona Umucyo: LED za COB zitanga urumuri rwinshi kandi zitanga urumuri rwiza, bigatuma zikoreshwa mu kumurikira abantu benshi.

(2) Gucunga neza ubushyuhe: Gushyira utubumbe ku byuma bitwara ubushyuhe mu buryo butaziguye bituma ubushyuhe bugabanuka neza, bigabanya ibyago byo gushyuha cyane kandi bikanoza igihe kirekire cy'amatara ya LED.

(3) Igishushanyo mbonera gito: Uduce twinshi twa LED dufatanye neza, bigatuma habaho urumuri rwinshi mu gace gato, ibyo bikaba byiza cyane ku bikorwa bisaba urumuri rwinshi kandi rungana.

(4) Kuramba no Kwizerwa: LED za COB zikunze kuramba kurusha LED za SMD ku giti cyazo, kuko utwuma dushyirwamo neza kandi ntitugira ikibazo cyo kwangirika bitewe no guhinda cyangwa guhungabana.

3. Ingaruka mbi za COB LEDs:

(1) Igiciro cyo hejuru: Udutara twa COB dukunze guhenda bitewe n'uburyo bwo gukora bugezweho ndetse n'ibikoresho byiza bikoreshwa mu gucunga ubushyuhe.

(2) Guhinduka guke: COB LEDs muri rusange zikoreshwa mu buryo bukomeye (nk'amatara adahinduka) kandi ntizihinduka nk'iza SMD LEDs, zishobora gushyirwa kuri PCBs zoroshye.

B. GOB (Gufata kole ku ikarita) ni iki?

GOB (Glue on Board) ni ikoranabuhanga rishya ryo gupfunyikamo LED rinoza ikoranabuhanga rya COB risanzwe rikoresha kole cyangwa indi coating iri kuri chip ya LED, ibyo bigatuma LED iramba kandi ikagira icyizere. GOB yagenewe gukumira kwangirika kwa chip za LED bitewe n'ibintu byo hanze nk'umukungugu, ubushuhe n'imitingito.

Mu gushyiraho GOB, nyuma yuko utwuma twa LED dushyizwe kuri PCB (nk'uko bimeze muri COB), urwego rwo kurinda rwa epoxy cyangwa silicon kole rushyirwa hejuru. Uru rwego rufasha:

- Kurinda uduce twa LED kwangirika kw'ibidukikije (umukungugu, ubushuhe, ingese).

- Kongera ubushobozi bw'urumuri no kugabanya ubushobozi bw'urumuri rushobora kwinjiza urumuri mu gihe rugaragara cyane.

- Kongera ubwizerwe ugenzura ko utwuma twa LED dukomeza gukora neza mu gihe kirekire, ndetse no mu bihe bikomeye.

Kole ikoreshwa mu ikoranabuhanga rya GOB inafasha mu kugira urumuri rusa neza no kugira ibara rihamye, ibyo bikaba ari ingenzi mu bikorwa nka Ecran za LED n'ibyapa binini.

1. Imiterere n'Ihame ry'Imikorere:

- Uduce twa LED dushyirwa ku gice cy'ubutaka (nk'icyuma gipima ubushyuhe) nk'uko bimeze mu buryo busanzwe bwa COB.

- Kole cyangwa epoxy bishyirwa hejuru y'udupira kugira ngo birinde kandi bifunze, bikongera imikorere ya module.

- Kurengera ibidukikije neza: Kole ikora uruzitiro rurinda ubushuhe, umukungugu, n'ibindi bintu bishobora kwangiza imikorere y'icyuma uko igihe kigenda gihita.

GOB ikunze gukoreshwa mu bikorwa byo kwamamaza hanze no mu bidukikije aho LED zishobora guhura n’ikirere, nk’amatara yo hanze, amatara yo ku muhanda, n’amatara aramba cyane yo mu nganda.

2. Ibyiza bya GOB LEDs:

(1) Kuramba neza: Urupapuro rwa kole rurinda rutuma utubumbe twa LED turindwa neza ingaruka mbi ku bidukikije, bigatuma utubumbe twa GOB LED tuba dukwiye gukoreshwa hanze no mu nganda.

(2) Gukwirakwiza urumuri neza: Kole ishobora gufasha kunoza uburyo urumuri rukwirakwira no kugabanya isura y'utudomo twijimye cyangwa urumuri rudakwirakwira, bigatuma habaho urumuri rumwe.

(3) Kurwanya Ubushuhe n'Umukungugu: Ikoranabuhanga rya GOB ryongera ubushobozi bwa LED bwo kurwanya ubushuhe, umukungugu n'ibindi bintu bihumanya, rikongera igihe cyaryo cyo kubaho no kunoza imikorere mu bidukikije bigoye.

(4) Kongera Kwizerwa: Mu gufata utwuma twa LED mu mwanya watwo ukoresheje urwego rwo kurinda, utwuma twa GOB ntabwo dushobora kwangirika cyane n'imbaraga zisanzwe zo hanze, nko guhindagura cyangwa gushotora.

3. Ingaruka mbi za GOB LEDs:

(1) Igiciro cyo hejuru: Kimwe na COB LEDs, GOB LEDs zirahenze cyane bitewe n'intambwe z'inyongera zo gukora n'ibikoresho byakoreshejwe muri icyo gikorwa.

(2) Guhindagurika Gukomeye: Kimwe na COB LEDs, GOB LEDs zikoreshwa mu buryo bukomeye kandi zishobora kudahinduka cyane mu buryo bworoshye.

(3) Gutakaza Ishusho: Urupapuro rwa kole rimwe na rimwe rushobora gutuma imikorere y’urumuri igabanuka gato, kuko rushobora gufata urumuri, nubwo iyi ngaruka ari nto ugereranije n’inyungu.
