Ama-PCB Okukhanya Kwe-LED Nokuphrojektha: Izinjini Zokukhanya Eziphezulu, Ukubhaliswa Kokukhanya kanye Nabashayeli

Ukukhanya okubonakalayo noma ukukhanya okukhanyayo kunomsebenzi owodwa: ukuphonsa ugongolo olulawulwayo nolunamandla lapho luqondiswe khona - ukugeza ubuso besakhiwo, ukukhetha ibhodi lokukhangisa, noma ukukhanyisa umbukiso. Lokho kudinga ukukhanya okuningi okuvela emthonjeni omncane, obekwe kahle, ngoba lapho ugongolo luqinile futhi luhlanzekile, kulapho ubuso obukhipha ukukhanya kufanele bube khona ngqo uma kuqhathaniswa ne-optic. Injini yokukhanya yilapho lokho kunemba kuhlala khona.

I-Highleap Electronics iyinkampani ekhiqiza i-PCB enekhono eliphelele kanye nefektri ephelele ye-PCBA , futhi izinjini ezihamba nge-flux ephezulu ezine-tight placement tolerances ziwuhlobo oludingayo lwe-metal-core kanye ne-COB work work imigqa yethu egxile kuyo. Sakha injini, umshayeli wamandla aphezulu, kanye nanoma yiliphi ibhodi lokulawula, bese sizihlanganisa zibe yimojuli evivinyiwe. Lo mhlahlandlela uhlanganisa ubunjiniyela be-flux ephezulu kanye nokubhaliswa kwe-optical izidingo zokukhanya, kanye nendlela yoku-oda. Isigaba esibanzi sisekhasini lethu lohlelo lwe-PCB lokukhanyisa.

Impendulo esheshayo: I-spotlight noma i-projection fixture idinga injini yokukhanya e-high-flux enobuso obukhipha ukukhanya obubekwe kahle kwi-optic, kanye nomshayeli wamandla aphezulu ukuze ayinike amandla. I-Highleap Electronics yakha futhi ihlanganise izinjini ze-COB kanye ne-high-density SMD kuma-substrate ensimbi noma ethusi ane-tight optical-registration tolerances, ama-driver ahambisanayo wamandla aphezulu, kanye nokuqina kwangaphandle kokusetshenziswa kwe-facade kanye nezimpawu - ku-MOQ 1 ngesilinganiso samahora angama-24.

Lokho ibhodi lokubonisa noma lokukhanyisa okufanele likunikeze

Izibani ezikhanyayo nezibani ezibonisa ukukhanya zihlukile ekukhanyeni okuvamile ngendlela eyodwa eqondile: ugongolo kufanele lulawulwe. Ukukhanya okuvamile kusabalalisa ukukhanya nxazonke; ugongolo lugxila ekhoneni logongolo oluchaziwe bese luluphonsa ibanga. Lokho kubeka izidingo ezimbili ebhodini - ukukhanya okuphezulu okuvela emthonjeni ohlangene, kanye nokubekwa ngqo kwalowo mthombo ukuze i-reflector noma ilensi ikwazi ukwakha ugongolo oluhlanzekile.

Ukuphuma okuphezulu endaweni encane kusho ubuningi bamandla aphezulu ngakho-ke ukushisa okukhulu, okuwumsebenzi wensimbi-core noma ithusi-core. Ukubeka kahle kusho ukuthi i-LED — ikakhulukazi indawo ekhipha ukukhanya ye-COB — kufanele ihlale lapho i-optic ikulindele khona, ukuze ikwazi ukumelana kahle. Ngakho-ke injini yokukhanyisa iyibhodi yokushisa kanye nebhodi yokunemba ngesikhathi esisodwa, yingakho kuwumsebenzi okhethekile.

Izinjini zokukhanya ezishintshashintshayo kakhulu kanye nokubhaliswa kwe-optical

Injini yokukhanyisa kufanele ihlolwe ngokucophelela, ngoba izinto ezimbili — ubuningi be-flux kanye nokubhaliswa kwe-optical — kunquma ukuthi i-fixture iphonsa umsebe oqinile, ohlanzekile noma ofiphele, ongalingani.

Ukukhanya okuphezulu okuvela emthonjeni ohlangene. Ukulawulwa kokukhanya kuyathuthuka njengoba umthombo uba mncane futhi ukhanya, yingakho ama-spotlight ethanda ama-emitter agxilile. I-COB (i-chip-on-board) ifaka ama-LED amaningi endaweni eyodwa encane ekhipha ukukhanya, okunikeza umthombo okhanyayo, ohlangene izidingo ze-optic ezinciphile. Ama-SMD arrays aphezulu enza umsebenzi ofanayo kwezinye izinto. Noma ngabe yikuphi ibhodi lithwala ama-watts amaningi endaweni encane:

• I-Copper-core kanye ne-high-conductivity metal core — ukususa ukushisa okugxilile ngokushesha nokugcina i-COB junction ipholile, ngokuvamile esikhungweni sethu insimbi-core noma, ukuze uthole izinto eziqinile kakhulu, umugqa wethusi-core.
• Ithusi elinzima lamanje — izinjini ezisebenzisa ugesi ophezulu zidonsa ugesi ophezulu, ngakho-ke ithusi elinzima umzila uyithwala ngaphandle kokulahlekelwa noma ukufudumeza.
• Isixhumi esibonakalayo sokushisa esitsheni sokushisa — injini yakhelwe ukuze ibe indlela yokushisa Isinki yokushisa yento imfushane futhi ayimelani kahle, ngoba i-COB eshisayo ilahlekelwa umkhiqizo futhi ishintsha umbala lapho ugongolo luyigxilisa khona.

Ukubhaliswa kwe-Optical — ukunemba okwenza i-beam. Lena yingxenye ukukhanya okuvamile okungakhathali ngayo. I-reflector noma ilensi encane yakha i-beam yayo kusukela ekukhanyeni okushiya umthombo, futhi icabanga ukuthi umthombo usesimweni esiqondile. Uma i-LED noma i-COB ihlala ngisho kancane — eceleni, ngokujikeleza, noma ngokuphakama — i-beam iyawohloka: isakazeka, ithuthukise izindawo ezishisayo, noma iphonsa iphethini engalingani. Ngakho-ke ibhodi kufanele ibeke i-emitter ngokunembile futhi inike i-optic okuthile okufanele ibhekane nakho:

• Ukubekezelelana kokubekwa okuqinile — inqubo yokuhlanganisa ibeka i-COB noma i-LED array ekubekezeleleni okuseduze okudingwa yi-optic, okuqine kakhulu kunezidingo zokukhanya kwe-flood noma kwephaneli.
• Izici zokubhalisa — ukuthola izimbobo, ama-fiducial, noma izinkomba zemishini ebhodini ukuze i-optic yesibili ihlale ihambisana kahle nendawo ekhipha ukukhanya njalo.
• Ukulawula ukukhanya okuphuma ebusweni — Indawo yokukhipha i-COB ihambisana nomklamo we-optic ngakho-ke umsebe uphuma njengoba kuchaziwe.
• Ukuphindaphinda — ibhodi ngalinye ekukhiqizeni libeka umthombo ngendlela efanayo, ngakho-ke yonke into iphonsa umsebe ofanayo; ukubekwa okungaguquki kusho iqoqo lezibani ezikhanyisayo ngalinye elihlose ngendlela ehlukile kancane.

Ukuhlanganisa i-flux density kanye nokubhaliswa kwe-optical yikho okuyisisekelo sokuklama injini ye-spotlight, futhi kuwumsebenzi wokuhlanganisa kanye nomsebenzi wokwakha. Ukwakha injini nokuyifanisa ne-optic kanye ne-driver endaweni eyodwa kuyindlela ukunemba kokubekwa, indlela yokushisa, kanye nogesi we-drive konke okuhambisana ngayo ukukhiqiza ugongolo oluhlanzekile noluphindaphindayo lapho kuhlulelwa khona i-projection fixture.

Abashayeli kanye nokufiphala kwezibani ezikhipha ukukhanya okuphezulu

Injini enamandla kakhulu idinga umshayeli ongakwazi ukuyondla kahle. Sakha amabhodi omshayeli ukuze kube nezibani ezikhipha amandla amaningi ezinamandla amanje futhi silawula lezi zinto ezilandelayo:

• Ugesi ophezulu oqhubekayo — ukuletha ugesi omkhulu odonswa yi-COB noma i-dense array, ngokulawulwa okuqinile kokukhipha okuzinzile.
• Ukufiphala nemiphumela — Ukulawula okungu-0-10 V, DALI, noma i-DMX kokubonisa izakhiwo nokuzijabulisa, okuhlanganisa nokuphela okubushelelezi.
• Izinketho zombala kanye nezilungisekayo — lapho i-fixture ishintsha umbala noma izinga lokushisa, ukulawula okuhlelekile kweziteshi.
• I-headroom eshisayo — umshayeli wenzelwe ukuthi asebenze kahle eceleni kwenjini eshisayo, njengoba bobabili behlanganyela i-fixture.

Yakhelwe ndawonye nenjini, amandla kagesi omshayeli abekwe ku-emitter eqondile futhi ukufiphala kugcina umbala ungashintshi kulo lonke ibanga.

Amabhodi angaphakathi kwento yokukhanyisa

I-projector fixture, ikakhulukazi eyokwakha noma yezimpawu, iwumkhiqizo onamabhodi amaningi, futhi sakha isethi:

• Injini yokukhanya ekhanya kakhulu — i-COB noma i-dense-SMD insimbi-core ibhodi elinokubhaliswa kwe-optical.
• Umshayeli wamandla aphezulu - the Umshayeli ukondla injini, ngokuvamile ngokulawula kwe-DMX/DALI.
• Ibhodi yokulawula imibala/imiphumela — yokushintsha umbala we-facade kanye nokuboniswa kwezimpawu.
• Ukuhlinzwa nokuvikelwa — yezakhiwo zangaphandle kanye nebhodi lokukhangisa elivezwe kugridi kanye nesimo sezulu.

Ukwakha lokhu ndawonye kusho ukuthi injini, i-optic, umshayeli, kanye nokulawula kuklanyelwe njengohlelo olulodwa lokwakha umsebe.

Ukuqina kwangaphandle kokubonisa ubuso kanye nezimpawu

Iningi lamaphuzu okukhanyisa abonisa izakhiwo nasemabhodini avela ngaphandle, ngakho amabhodi athola ukwelashwa kwangaphandle: izinsizakalo zokufaka i-conformal ngokumelene nomswakama, ukuvikelwa kokukhuphuka kwemishini exhunywe kugridi, kanye nomklamo wokushisa obamba ilanga lasehlobo ngqo phezu kokushisa kwenjini. Ngemishini yokuhlobisa egeza izindawo ezinkulu sakha nezinjini zokukhanya kwezikhukhula ezihlobene , futhi sifanisa izinga lokuvikela nokufakwa kanye nesimo sezulu ngesikhathi sokubuyekezwa kwe-DFM.

Kungani ifektri eyodwa yenjini, ibhodi elilungele ukukhanya, kanye nomshayeli

I-spotlight iyahlulelwa emsebeni wayo, futhi umsebe uncike ekutheni i-emitter ibekwe kahle, ipholiswe kahle, futhi iqhutshwa kahle — izinto ezintathu okumele zivumelane. Lapho ukubekwa, ukwakheka kokushisa, kanye nomsinga wokushayela kuvela kubaphakeli abahlukene, umsebe uyahlupheka futhi akekho ophethe umphumela. Lapho umenzi oyedwa ebeka i-emitter ekubekezelelekeni, eklama indlela yokushisa, futhi efanisa umshayeli, i-fixture iphonsa umsebe ohlanzekile, ophindaphindwayo owaklanyelwa wona.

I-Highleap Electronics yakha injini ye-high-flux ngokubhaliswa kwe-optical, umshayeli wamandla aphezulu, kanye nebhodi lokulawula ndawonye, ​​ku-MOQ 1 ukuze ukwazi ukufakazela i-beam ngaphambi kwevolumu. Thumela i-target flux yakho, i-beam angle, kanye ne-optic eqenjini lethu le-LED PCBA ukuze uthole isilinganiso samahora angama-24.

I-PCB ye-LED Ebonakalayo Neye-Projektha — Imibuzo Evame Ukubuzwa

Kungani ukubekwa kwe-LED kubaluleke kangaka ekukhanyeni kodwa hhayi ekukhanyeni kwephaneli?

Ngoba i-optic ye-spotlight yakha umsebe oqinile futhi icabanga ukuthi indawo ekhipha ukukhanya isendaweni eqondile. Uma i -COB noma i-LED array ihlala kancane — eceleni, ngokujikeleza, noma ngokuphakama — umsebe uyasabalala, wakhe izindawo ezishisayo, noma uhlose ngokungalingani. Ukukhanya kwephaneli kusabalalisa ukukhanya nxazonke futhi akunandaba. Ngakho-ke izinjini ze-spotlight zihlanganiswa ukuze zibeke kahle izici zokubhalisa (i-fiducials, ukuthola izimbobo) ukuze izihlalo ze-optic zihambisane kahle njalo, futhi wonke amabhodi asebenza kahle abeka umthombo ngendlela efanayo.

Ungakwazi yini ukwakha izinjini ze-COB ezisebenza kahle kakhulu futhi uzigcine zipholile?

Yebo. Izibani ezikhanya kakhulu zigxila ama-watts amaningi endaweni encane, ngakho sakha izinjini ze-COB kanye ne-dense-SMD kuma- substrate ensimbi-core noma ethusi-core anethusi elisindayo lamandla kagesi, futhi sakha indlela yokushisa emfushane, engamelani kakhulu ne-heat sink ye-fixture. Ukugcina i-COB junction ipholile kubaluleke kakhulu lapha kunanoma yikuphi, ngoba i-hot emitter ilahlekelwa yi-output futhi ishintsha umbala khona kanye lapho i-beam iyigxilisa khona.

Ingabe uyakha umshayeli kanye nokulawula umbala kanye nenjini?

Yebo. Sakha umshayeli wamandla aphezulu ophakela injini eguquguqukayo ephezulu, enokulawula okungu-0-10 V, DALI, noma i-DMX kokubonisa izakhiwo nokuzijabulisa, kanye namabhodi okulawula imibala/imiphumela yobuso obushintsha umbala kanye nezinto zokufaka izimpawu. Njengoba yakhiwe kanye nenjini, umshayeli wamandla usethwe ku-emitter eqondile futhi ukufiphala kugcina umbala ungashintshi kulo lonke ibanga.

Ingabe lezi zinto zingasetshenziswa ngaphandle ezindongeni nasemabhodini okukhangisa?

Yebo. Izibani eziningi ze-projection zingaphandle, ngakho-ke sengeza i-conformal coating ngokumelene nomswakama, ukuvikelwa kokukhuphuka kwezinto ezixhunywe kugridi, kanye nomklamo wokushisa osinda elangeni eliqondile phezu kokushisa kwenjini. Sifanisa izinga lokuvikela nokufakwa kanye nesimo sezulu ngesikhathi sokubuyekezwa kwe-DFM, futhi sakha izinjini zokukhanya kwezikhukhula ezihlobene nezinto zokugeza ubuso.
