Nkọwa nke COB encapsulation
A na-akpọ COB Chips on Board (COB), nke bụ nkà na ụzụ iji dozie nsogbu nke ọkụ ọkụ ọkụ LED. E jiri ya tụnyere teknụzụ in-line na SMD, ọ nwere ọtụtụ atụmatụ nke ịchekwa ohere, nkwakọ ngwaahịa dị mfe, yana njikwa okpomọkụ dị oke mma.
Ihe mkpuchi COB, ya bụ, mgbawa nọ n'ụgbọ ahụ, bụ ijigide mgbawa ahụ na-enweghị ihe jikọrọ ya na gluu na-eduzi ma ọ bụ nke na-adịghị eduzi, wee rụọ njikọ waya iji nweta njikọ eletrik. Ọ bụrụ na mgbawa ahụ na-adịghị ahụ ekpughere ozugbo na ikuku, ọ nwere ike ibute mmetọ ma ọ bụ mmebi nke mmadụ, na-emetụta ma ọ bụ mebie ọrụ nke mgbawa ahụ, ya mere mgbawa na eriri njikọ na-ekpuchi ya site na gluu. A na-akpọkwa ngwugwu a dị ka mkpuchi dị nro.
Uru nke nkwakọ ngwaahịa COB
1. Ultra-mkpa: Dị ka n'ezie mkpa nke ndị ahịa, PCB osisi na ọkpụrụkpụ si 0.4-1.2mm nwere ike iji belata arọ ka 1/3 nke mbụ omenala ngwaahịa, nke nwere ike budata ibelata structural, njem na engineering akwụ ụgwọ maka ndị ahịa.
2. Mgbochi na mkpakọ: Ngwaahịa COB na-ekpuchi ọkụ ọkụ ọkụ ọkụ na concave oriọna ọnọdụ nke PCB osisi, wee gwọọ ya site epoxy resin. Elu nke oriọna ahụ bụ convex n'ime mbara okirikiri, nke dị nro ma sie ike, na-eguzogide nkukota na iyi.
3. Nnukwu nlegharị anya: ngwugwu COB na-eji ọkụ na-emighị emi nke ọma, ihe nlele ahụ karịrị ogo 175, dị nso na ogo 180, ma nwee mmetụta dị mma na-agbasa ngwa ngwa anya.
4. Bendable: Ikwenye ikike bụ ihe pụrụ iche nke mgbakọ COB. PCB na-ehulata adịghị emebi emebi nke ibe LED ekpuchiri. Ya mere, LED arc screens, okirikiri okirikiri, na wavy screens nwere ike na-adị mfe chepụta site na iji COB modul. Ọ bụ ihe dị mma maka ihuenyo ahaziri iche na ụlọ mmanya na ụlọ oriri na ọṅụṅụ abalị. Enwere ike ịgbatị ya n'enweghị ihe ọ bụla, usoro mmepụta ahụ dị mfe, ọnụ ahịa ya dịkwa ala karịa ihuenyo ekara ikanam nke bọọdụ sekit na-agbanwe agbanwe na modul ngosi ọdịnala.
5. Mgbasa ọkụ siri ike: A na-etinye ngwaahịa COB na osisi PCB, na ọkụ nke wick na-ebufe ngwa ngwa site na mpempe ọla kọpa na osisi PCB. Ọkpụrụkpụ nke foil ọla kọpa nke bọọdụ PCB nwere ụkpụrụ teknụzụ siri ike, yana n'ihi usoro imikpu ọla edo, ọ naghị ebute oke ọkụ ọkụ. Ya mere, enwere mmebi LED ole na ole na ngwaahịa COB na-agbatị ndụ.
6, eyi na-eguzogide, dị mfe ihicha: elu nke oriọna oriọna bụ convex n'ime a sppherical elu, dị nro na ike, nkukota na-eguzogide ma na-eguzogide; Ọ bụrụ na enwere ntụpọ nwụrụ anwụ, ị nwere ike ịrụzi ebe site na isi; enweghị ihe nkpuchi, enwere ike iji mmiri ma ọ bụ akwa hichaa uzuzu.
7, Njirimara ihu igwe kachasị mma: ọgwụgwọ nchebe okpukpu atọ, enweghị mmiri, ihe akaebe mmiri, nguzogide corrosion, mgbochi uzuzu, imecha ihe mgbochi, mgbochi oxidation, mmetụta mgbochi UV pụtara ìhè. Ya mere, ọ nwere ike izute ọnọdụ ọrụ ihu igwe niile, ọdịiche okpomọkụ nke mwepu ogo 30 ruo efu 80 ka nwere ike iji ya mee ihe.
