GOB vs. COB 3 nkeji Ntuziaka ngwa ngwa 2024

1. Okwu mmalite

Ka ngwa ihuenyo ngosi LED na-agbasawanye, ihe a na-achọ maka ogo ngwaahịa na arụmọrụ ngosi abawanyela. Teknụzụ SMD ọdịnala enweghịzi ike igbo mkpa ụfọdụ ngwa. Ya mere, ụfọdụ ndị na-emepụta ihe na-atụgharị gaa na ụzọ mkpuchi ọhụrụ dị ka teknụzụ COB, ebe ndị ọzọ na-akawanye mma na teknụzụ SMD. Teknụzụ GOB bụ nrụgharị nke usoro mkpuchi mkpuchi SMD emelitere.

Ụlọ ọrụ ngosi LED ewepụtala ụzọ mkpuchi dị iche iche, gụnyere ihe ngosi COB LED. Site na teknụzụ DIP mbụ (Direct Insertion Package) na teknụzụ SMD (Surface-Mount Device), wee pụta na COB (Chip on Board) encapsulation, na n'ikpeazụ ọbịbịa nke GOB (Glue on Board) encapsulation.

Teknụzụ GOB nwere ike mee ka ngwa sara mbara maka ihuenyo ngosi LED? Kedu usoro anyị nwere ike ịtụ anya na mmepe ahịa nke GOB n'ọdịnihu? Ka anyị gaa n'ihu.

2. Gịnị bụ GOB Encapsulation Technology?

2.1GOB LED ngosibụ ihuenyo ihe ngosi LED nke na-echebe nke ukwuu, na-enye ihe mgbochi mmiri, ihe na-egosi mmiri, mmetụta na-eguzogide, uzuzu uzuzu, na-eguzogide corrosion, blue ìhè na-eguzogide, nnu na-eguzogide, na mgbochi static ike. Ha anaghị emetụta oke okpomọkụ ma ọ bụ mfu nchapụta. Nnwale dị ukwuu na-egosi na gluu na-eji GOB eme ihe ọbụna na-enyere aka na ikpo ọkụ ọkụ, na-ebelata ọdịda nke LED, na-eme ka nkwụsi ike nke ngosi ahụ dịkwuo elu, ma si otú a na-agbatị ndụ ya.

2.2 Site na nhazi GOB, isi ihe pikselụ granular na mbụ na ihuenyo GOB LED na-agbanwe ka ọ bụrụ ebe dị larịị, dị larịị, na-enweta mgbanwe site na isi iyi gaa na isi ọkụ. Nke a na-eme ka ìhè panel panel nke LED na-eme ka ọ bụrụ otu na mmetụta ngosi doro anya na nke ọma. Ọ na-eme ka akụkụ nlele ahụ dịkwuo elu (ihe fọrọ nke nta ka ọ bụrụ 180 ° n'ihu na kwụ ọtọ), na-ewepụ usoro moiré nke ọma, na-eme ka ọdịiche ngwaahịa dịkwuo mma, na-ebelata ìhè na mmetụta dị egwu, na-ebelata ike ọgwụgwụ anya.

3. Gịnị bụ COB Encapsulation Technology?

Ihe mkpuchi COB pụtara ịtinye mgbawa ozugbo na mkpụrụ PCB maka njikọ eletrik. Ebu ụzọ webatara ya iji dozie nsogbu mkpofu ọkụ nke mgbidi vidiyo LED. Tụnyere DIP na SMD, mkpuchi mkpuchi COB na-eji nchekwa ohere, ọrụ mkpuchi dị mfe, yana njikwa okpomọkụ nke ọma. Ugbu a, a na-ejikarị COB encapsulation eme ihe naezigbo pitch LED ngosi.

4. Gịnị bụ Uru nke COB LED Ngosipụta?

Ultra-dị mkpa na ọkụ:Dịka mkpa ndị ahịa si dị, enwere ike iji bọọdụ PCB nwere ọkpụrụkpụ sitere na 0.4 ruo 1.2mm, na-ebelata ịdị arọ ka ọ dịkarịa ala otu ụzọ n'ụzọ atọ nke ngwaahịa ọdịnala, na-ebelata ụkpụrụ, njem, na ọnụ ahịa injinia maka ndị ahịa.

Mmetụta na Nguzogide Nrụgide:Ngosipụta COB LED na-ekpuchi mgbawa LED ozugbo na ọnọdụ concave nke bọọdụ PCB, wee kpuchie ya ma gwọọ ya na gluu resin epoxy. Elu nke ebe ọkụ na-apụta, na-eme ka ọ dị nro na nke siri ike, na-eguzogide mmetụta, na-eyi ihe.

Akụkụ Nlele sara mbara:COB encapsulation na-eji ọkụ na-emighị emi nke ọma gburugburu, nwere akụkụ nlele karịrị ogo 175, dị nso na ogo 180, ma nwee mmetụta ọkụ anya gbasasịrị nke ọma.

5. Kedu ihe dị iche n'etiti COB na GOB?

Isi ihe dị iche n'etiti COB na GOB dị na usoro ahụ. Ọ bụ ezie na mkpuchi COB nwere ihu dị mma na nchebe dị mma karịa ihe mkpuchi SMD ọdịnala, GOB encapsulation na-agbakwunye usoro ngwa gluu na ihuenyo ihuenyo, na-eme ka nkwụsi ike nke oriọna LED na-ebelata nke ukwuu ohere nke ịdaba ọkụ, na-eme ka ọ kwụsie ike.

6. Kedu nke bara uru karị, COB ma ọ bụ GOB?

Enweghị azịza doro anya maka nke ka mma, ihe ngosi COB LED ma ọ bụ ihe ngosi GOB LED, n'ihi na ịdị mma teknụzụ encapsulation dabere n'ihe dị iche iche. Isi echiche bụ ma ị na-ebute ụzọ arụmọrụ nke oriọna LED ma ọ bụ nchebe enyere. Teknụzụ encapsulation ọ bụla nwere uru ya na enweghị ike ikpe ikpe zuru ụwa ọnụ.

Mgbe ị na-ahọrọ n'etiti COB na GOB encapsulation, ọ dị mkpa ịtụle gburugburu nrụnye na oge ọrụ. Ihe ndị a na-emetụta njikwa ọnụ ahịa na ọdịiche dị na arụmọrụ ngosi.

Ma teknụzụ mkpuchi GOB na COB na-enye uru pụrụ iche maka ngosipụta LED. GOB encapsulation na-eme ka nchebe na nkwụsi ike nke oriọna LED, na-enye ezigbo ihe mgbochi mmiri, uzuzu uzuzu, na ihe mgbochi, ma na-eme ka ikpo ọkụ ọkụ na ịrụ ọrụ anya. N'aka nke ọzọ, COB encapsulation na-eme nke ọma n'ichekwa oghere, njikwa okpomọkụ dị mma, na inye ngwọta dị arọ, na-eguzogide mmetụta. Nhọrọ n'etiti COB na GOB encapsulation na-adabere na mkpa dị iche iche na ihe ndị dị mkpa nke gburugburu ebe nrụnye, dị ka ogologo oge, njikwa ego, na àgwà ngosi. Teknụzụ ọ bụla nwere ike ya, a ga-eme mkpebi ahụ dabere na nyocha zuru oke nke ihe ndị a.
