Yintoni umahluko phakathi kweGob kunye neCOB?

Kwihlabathi letekhnoloji ye-LED, amagama athi GOB kunye ne-COB adla ngokuxoxwa ngawo xa kujongwa iimodyuli ze-LED ezisebenza kakuhle kwizicelo ezahlukeneyo. Ezi teknoloji zimbini zokupakisha ze-LED zibalulekile ekuqinisekiseni ukuqina, ukusebenza kakuhle, kunye nokukhanya kwezibane ze-LED. Nangona kunjalo, nangona zombini i-GOB kunye ne-COB zibhekisa kwiindlela zokufaka iitships ze-LED, zahlukile kakhulu ngokwesakhiwo, usetyenziso, kunye nokusebenza.

A. Yintoni i-COB (i-Chip on Board)Isikrini se-LED?

I-COB (iChip on Board) yiteknoloji esetyenziselwa ukufaka iitships ezininzi ze-LED ngqo kwi-substrate ngaphandle kokupakisha kwendabuko. Kwi-COB LED eqhelekileyo, iitships ezininzi ze-LED zincamathiselwa kwibhodi enye okanye kwi-substrate, nto leyo evumela uyilo oluncinci nolusebenzayo. Ii-COB LED zibonelela ngokukhanya okuphezulu kwindawo encinci, nto leyo ezenza zibe sisisombululo esifanelekileyo kwizicelo zokukhanya eziphezulu nezorhwebo.

1. Ulwakhiwo kunye noMgaqo-siseko wokuSebenza:

Kwi-COB LED, iitships ze-LED ngazinye zezi:

- Zifakwe ngqo kwi-substrate: Iitships ze-LED zibekwe kwisiseko, esihlala sisixhobo esinomoya ofanelekileyo wokushisa, njenge-aluminium, ukunceda ukukhupha ubushushu ngokufanelekileyo.

- Iqhagamshelwe ngombane: Iitships zixhunywa ngqo ebhodini, nto leyo evumela ukuhamba kombane okusebenzayo kunye nokusasazwa kwamandla.

- Ulawulo lobushushu: Ii-COB LED zihlala zisebenzisa ii-metal core PCBs (MCPCB), ezinceda ekuchitheni ubushushu kwaye zonyusa ixesha elide kunye nokusebenza kakuhle kwee-LED.

Itekhnoloji ye-COB ithandwa kakhulu kwii-applications ze-Commercial show, ezifana ne-advertising yangaphakathi, i-advertising yangaphandle, kunye ne-conference, kuba ivumela ukukhanya okuphezulu kunye nokufana kokukhanya okugqwesileyo.

(1) Ukusebenza kakuhle okuKhanyayo: Ii-COB LED zivelisa amanqanaba aphezulu okukhanya kwaye zibonelela ngokukhanya okugqwesileyo, nto leyo ezenza zifaneleke ukukhanyisa okukhulu.

(2) Ulawulo olungcono lobushushu: Ukufakelwa ngokuthe ngqo kweetships kwi-substrates eziqhuba ubushushu kuqinisekisa ukuba ubushushu bususwa ngokufanelekileyo, kunciphisa umngcipheko wokutshisa kakhulu kwaye kuphucule ixesha elide lee-LED.

(3) Uyilo oluQhelekileyo: Iitships ezininzi ze-LED zipakishwe ndawonye, ​​nto leyo eyenza ukukhanya okuninzi kwindawo encinci, nto leyo efanelekileyo kwiizicelo ezifuna ukukhanya okuqinileyo nokulinganayo.

(4) Ukuqina Nokuthembeka: Ii-COB LEDs zihlala ixesha elide kunee-SMD LEDs ezahlukeneyo, njengoko iitships zifakwe ngokuqinileyo kwaye azichaphazeleki lula kumonakalo ovela kwiintshukumo okanye kwiishocks.

3. Iingxaki ze-COB LEDs:

(1) Ixabiso Eliphezulu: Ii-COB LED zihlala zibiza kakhulu ngenxa yenkqubo yokuvelisa ephucukileyo kunye nezixhobo ezisemgangathweni ezisetyenziselwa ulawulo lobushushu.

(2) Ukuguquguquka Okulinganiselweyo: Ii-COB LED zihlala zisetyenziswa kwizicelo eziqinileyo (ezifana nokuseta ukukhanya okuzinzileyo) kwaye aziguquguquki njengee-SMD LED, ezinokufakelwa kwii-PCB eziguquguqukayo.

B. Yintoni i-GOB (iGlue on Board)?

I-GOB (iGlue on Board) yiteknoloji entsha yokupakisha ye-LED ephucula iteknoloji ye-COB yendabuko ngokusebenzisa i-coating eyongezelelweyo yokukhusela okanye iglu kwi-chip ye-LED, ephucula ukuqina kunye nokuthembeka kwe-LED. I-GOB yenzelwe ukuthintela ukonakala kwiitships ze-LED ezivela kwizinto zangaphandle ezifana nothuli, ukufuma, kunye nokungcangcazela.

Kwisetingi ye-GOB, emva kokuba iitships ze-LED zifakwe kwi-PCB (njengakwisetingi ye-COB), umaleko okhuselayo we-epoxy okanye i-silicon glue ufakwa kumphezulu. Olu maleko lusebenza ku:

- Khusela iitships ze-LED ekonakaleni kwendalo (uthuli, ukufuma, ukugqwala).

- Ukuphucula ukukhutshwa kokukhanya nokusebenza kakuhle ngokunciphisa ukufunxwa kokukhanya okunokwenzeka xa kubekwe kwindawo evulekileyo.

- Yandisa ukuthembeka ngokuqinisekisa ukuba iitships ze-LED zihlala zikwindawo yazo kwaye zisebenza ixesha elide, nokuba ziphantsi kweemeko ezinzima.

Iglue esetyenziswa kubuchwepheshe be-GOB ikwanceda ekukhanyeni okufanayo kunye nokungaguquguquki kombala, nto leyo ibalulekileyo kwizicelo ezifana Iziboniso ze-LED kunye neempawu ezinkulu.

1. Ulwakhiwo kunye noMgaqo-siseko wokuSebenza:

- Iitships ze-LED zifakwe kwi-substrate (njenge-PCB) njengakwisetingi ye-COB eqhelekileyo.

- Iglue okanye i-epoxy ifakwa phezu kweetships ukuze zikhuseleke kwaye zitywinwe, nto leyo ephucula ukusebenza kwemodyuli.

- Ukhuseleko olungcono lokusingqongileyo: Iglu yenza umqobo othintela ukufuma, uthuli, kunye nezinye izinto ezingcolisayo ezinokonakalisa ukusebenza kwetshiphu ngokuhamba kwexesha.

I-GOB isetyenziswa kakhulu kwiindawo zokuthengisa zangaphandle kunye neendawo apho ii-LEDs zinokujongana nokuvezwa kwezinto ezinje ngeziboniso zangaphandle, izibane zesitalato, kunye neenkqubo zokukhanyisa zoshishino ezihlala ixesha elide.

2. Iingenelo ze-GOB LEDs:

(1) Ukuqina Okuphuculweyo: Umaleko weglue okhuselayo uqinisekisa ukuba iitships ze-LED zikhuselekile ngcono kwiingozi zokusingqongileyo, nto leyo eyenza ii-GOB LED zilungele ukusetyenziswa ngaphandle nakwemizi-mveliso.

(2) Ukusasazwa Kokukhanya Okungcono: Iglu inokunceda ukuphucula ukusasazwa kokukhanya kwaye inciphise ukubonakala kwamabala amnyama okanye ukukhanya okungalinganiyo, iqinisekisa ukukhanya okufanayo.

(3) Ukumelana nokufuma nothuli: Itekhnoloji ye-GOB yonyusa ukumelana kwe-LED kumswakama, uthuli, nezinye izinto ezingcolisayo, yandisa ubomi bayo kwaye iphucula ukusebenza kwiindawo ezinzima.

(4) Ukuthembeka Okuphuculweyo: Ngokugcina iitships ze-LED endaweni yazo ngomaleko okhuselayo, ii-GOB LED azinakwenzeka ukuba zonakaliswe ngamandla angaphandle endalo, afana nokungcangcazela okanye ukuthuthumela.

3. Iingxaki ze-GOB LEDs:

(1) Ixabiso Eliphezulu: Njengee-COB LED, ii-GOB LED zibiza kakhulu ngenxa yamanyathelo ongezelelweyo okuvelisa kunye nezixhobo ezisetyenzisiweyo kule nkqubo.

(2) Ukuguquguquka okulinganiselweyo: Njengee-COB LED, ii-GOB LED zihlala zisetyenziswa kwiindawo eziqinileyo kwaye zisenokungabi lula ukuzisebenzisa xa zitshintshatshintsha.

(3) Ukulahleka Okunokwenzeka Kokukhanya: Umaleko weglue ngamanye amaxesha unokubangela ukuncipha okuncinci kokusebenza kokukhanya, njengoko unokufunxa ukukhanya okuthile, nangona esi siphumo sincinci xa kuthelekiswa neenzuzo.
