Kuwedzera Tembiricha Resistance Chiedza -emitting Diode Structure

LED mwenje bead kudira machipisi, isina kurongedzerwa hunyanzvi ichangobva kukonzera bhizimusi repamusoro-tech muindasitiri ye LED. Nekuda kwechinyakare mwenje mabheji e LED, maitiro ekuumbwa kwekupisa kupisa, kutadza kwechiedza uye humwe hunyanzvi mabhodhoro. LED rambi bead kudurura machipisi uye unpackage hunyanzvi kare makore 10 apfuura, nyika dzekunze kuti mari muhombe guru tsvakurudzo. Iyo yakanangwa nemwenje we LED mabheji kubva kune substrate glue uye zviyo zvakananga welding hunyanzvi. Iyo inopedzwa zvachose ne LED mwenje mabheji machipisi ekuonekwa kwezvirwere zvakawanda zvebvudzi, zvichibvumira mabheji emwenje e LED kuti amire kushivirira kwekushisa kwakanyanya uye kuwedzera mabheji emwenje e LED. Iyo indasitiri iri pamusoro pekucheka-kumucheto hunyanzvi hweiyo LED marambi mabheji ekurongedza. & LED Lighting Daspeed Mangani wnbsp; asi mubvunzo ndouyu: Sei LED rambi bead kudira unyanzvi? Kuvimba nealuminium (mhangura) substrates, ceramic substrate processing molding, uye kuiswa hakusi nyore sesimbi substrates, nokuti (kaviri) tin welding inofanira kumira 280 degrees yekushisa kwepamusoro, iyo isingagoni kubatsira asi kukonzera kukanganisa kwezvinhu uye zvikamu. Ceramic substrates uye simbi substrates haisi yakakwirira kupfuura ratidziro chiyero, uye chenguva pfupi chiedza mhedzisiro yakaoma kuvandudza. Iyo shoma yekupisa yekupisa mwero weceramic substrates uye iyo yakaganhurirwa chip yekubatanidza nzvimbo zvakare yakaganhura kwayo yakagadzika mwenje mhedzisiro. Kudururira mwenje wemwenje we LED kaviri mukati metin welding uye ceramic substrate aruminiyamu substrate dual thermal resistance inokwana kumisa mhepo yekumusoro ichangobva kutaurwa. Uye zvakare, iyo yekupisa yekumanikidza welding uye reflux welding yemwenje ye LED mabheji yakanyanya kukwirira, uye goho harina kugadzikana. Kubva pamaonero evashandisi vekupedzisira, yakanaka LED mudziyo unofanirwa kuve nemhando yemwenje iri nani, mabasa emwenje epamusoro, mitengo yakaderera yehurongwa uye nekukurumidza kudzoka kwekudyara. Kubata hunyanzvi hwekudurura mwenje we LED mune ramangwana (LM yuan) kukosha. Mune imwe pfungwa, mwenje we LED mabheji ekurongedza ekutarisa hunyanzvi ndiko kusimudzira uye kugadzira hunyanzvi hwemabhureki ekurongedza. COB LED mwenje bead encapsulation uye imwe -chip LED mwenje bead packaging yakaratidza masimba mazhinji maererano nechiedza chakasimba, kupisa kupisa, kugovera mwenje, mutengo, nezvimwe. Iwo echinyakare COB LED mwenje mabhedhi iko zvino ndiyo bracket inoshandisa aluminium (kana mhangura) substrates kubatanidza iyo FR4 fiber board mune imwe. Domestic FR-4 semi-curing tablets, thermal conductivity inongova 0.3/m-k, yakanakisa yekupinda ingori 2.0/m-k kumutengesi, nepo yakachena aluminium yekudziya coefficient iri 237/m-k. Inofanira kuwedzera kupisa kwekupisa kwegadziriro, zvichiita kuti mabheji emwenje e LED awedzere kuora uye kuderedza hupenyu hwebasa. Naizvozvo, pfungwa dzevanhu-ku-pfungwa pfungwa dzinobvisa iyo insulation fiber yealuminium substrates. “LMCOB bracket ”(Kuchera ganda remhangura uye insulating layer yealuminium substrate), asi inogumira kune chikonzero chemidziyo, gel, maitiro uye mutengo, uye haisati yasimudzirwa. Mukuwedzera, iyo misika yemazuva ano inonyanya kufarirwa inonzi inonzi “Integrated light source ”Nyanzvi, ichibvuma kuumbwa kwejekiseni rekuisa ndiro ye electrode muPPA (kana kuti EMC iri kusunda parizvino), nekuti PPA inozoita yero poda pasi pekudziya kwakanyanya uye ultraviolet irradiation, zvichikonzera mvura inofema nemvura. Mamiriro acho ndeokuti ndiro ye electrode yakakwirira kudarika chip 1.5 sisi, uye fluorescent poda uye gel dosage zvakasakara. Haisi kuzongowedzera mutengo wekurongedza, yakawandisa colloids ichakanganisawo kutapurirana. Parizvino, ese COB LED mwenje bead mabhuraketi haana kunze kwekumisikidza yakavharirwa dhizaini kuti ivhare fluorescent kuvhiringika kwemazingamu pasina kupera, nekuti dhamu gel uye pamusoro chena mafuta anotora mwenje. Pakutanga, kusimba kwechiedza uye kupisa kweguta ndicho chikonzero chakakosha chechinguvana chechiedza chetsika COB LED mwenje bead mwenje sosi uye kuoma kwe steady -state light effect. Mukugadzirwa kwemarambi e LED, mubvunzo unowanzo bvunzwa 5052LED mwenje webhedhi mubvunzo ndewekuti ungasarudza sei magetsi ekufambisa, uye kutaura zvazviri mabheji emwenje e LED anodonhedzwa kana kuparadzwa, uye chikamu chesimba rekutyaira chinokwanisa. Chiedza bhedhi mwenje hunyanzvi bhodhi pfupi. Nekudaro, iyo COB LED mwenje mabheji aruminiyamu substrates yakagamuchira yakagadzika yekurongedza dhizaini yesimba rinopisa, uye (iyo chip inotaurwa zvakananga pane substrate).
