Siyakwamukela. Uma uhlela iphrojekthi yokukhanyisa, ukuvuselela isikhala, noma umane nje ufuna ukwazi ngezinketho ze-LED zesimanje, umehluko phakathi kobuchwepheshe obubili obudumile be-strip ubaluleke kakhulu kunalokho ongase ukucabange. Kulesi sihloko uzothola ukubuka okucacile, okusebenzayo, nokujulile kokuthi izinhlobo ezimbili zokukhanyisa kwe-strip ye-LED ziziphatha kanjani, ukuthi yini eyenza zikhange ekusetshenzisweni okuhlukile, nokuthi ungakhetha kanjani okulungile ngezidingo zakho.

Kungakhathaliseki ukuthi ufuna ukukhanyisa okugqamile okungenamthungo kwesibonisi sezitolo esisezingeni eliphezulu, ikhambi elingabizi kakhulu lokukhanyisa i-cove, noma inketho eqinile yezindawo zezimboni, ukuqonda izinzuzo nezingozi zobuchwepheshe ngabunye kuyisinyathelo esibalulekile. Qhubeka ufunda ukuze uthole izici zobuchwepheshe kanye nezinto zangempela ezizokusiza wenze ukukhetha okunolwazi.

Ukuqonda ubuchwepheshe be-COB kanye ne-SMD LED

Amagama asetshenziselwa ukuchaza ukukhanya kwe-LED strip—i-COB kanye ne-SMD—abhekisela ezindleleni ezihlukene kakhulu zokupakisha nokuhlela ama-diode akhipha ukukhanya emugqeni. I-SMD imele i-Surface Mount Device, echaza ama-LED apakishwe njengama-diode ngamanye futhi afakwe emugqeni ngezikhathi ezihlukene. Ingxenye ngayinye ye-SMD ngokuvamile iqukethe i-semiconductor chip eyodwa noma ngaphezulu ehlanganiswe ngaphakathi kwephakheji encane engunxande. Ngokuphambene nalokho, i-COB imele i-Chip On Board, indlela lapho ama-LED chip amaningi afakwa khona ngqo ku-strip substrate bese embozwa ungqimba oluqhubekayo lwe-phosphor noma i-resin. Lokhu kuphumela emthonjeni wokukhanya ofanayo, ofana ne-tape onezindawo ezimbalwa ezibonakalayo.

Ngokombono wokukhiqiza, imichilo ye-SMD LED iyimodeli futhi iyaguquguquka ngokwemibala exutshwe kanye nokukhetha kwamandla. Iphakheji ngayinye ye-SMD ingaklanywa ukuthi ifake ukucushwa okuhlukile kwama-chip okukhanya okumhlophe, i-RGB, noma okukhiphayo kwemibala eminingi, futhi abakhiqizi bangazibeka ngobuningi obuhlukahlukene kuye ngokuthi kungakanani okukhiphayo kwe-lumen okudingekayo kanye nemikhawulo yesikhala. Imichilo ye-COB, ngokuphambene, igxila ekuqineni nasekuqhubekeni. Ngenxa yokuthi ama-chip abekwa ngqo ku-substrate futhi ambozwe ngokulinganayo, imichilo ye-COB inganikeza okukhiphayo kokukhanya okuhambisanayo futhi inciphise umphumela "we-hot spot" owenzeka ngezinye izikhathi ngama-diode e-SMD ahlukaniswe kakhulu.

Ngokubona, imichilo ye-SMD izobonisa amaphuzu okukhanya ngamanye uma ibonwa eduze, ikakhulukazi uma ubuningi be-SMD buphansi. Lesi sici somthombo wephuzu singaba wusizo lapho ukukhanya okuqondisiwe kufunwa noma lapho iphethini ye-beam ye-diode ngayinye isetshenziswa ezicini. Imichilo ye-COB iyathandwa lapho ukukhanya komthombo ongabonakali kudingeka—izimo lapho umchilo kufanele uvele njengomugqa oqinile wokukhanya kunokuba uchungechunge lwamachashazi. Lo mehluko uthinta imiphumela yobuhle kanye nokusebenza kokusebenza ekufakweni okufana nokukhanyisa emuva, ukukhanyisa ngaphansi kwekhabhinethi, kanye nokukhanyisa okusemaphethelweni.

Ngogesi, amaphethini okuxhuma nawo ayahluka. Imichilo ye-SMD ivame ukulungiselelwa ngamaqembu ama-LED axhunywe ngochungechunge oluhambisanayo ukuze ivumelane nezidingo ezithile ze-voltage kanye nezamanje, okubonisa amaphuzu okusika futhi kuthinte indlela imichilo ehlanganiswa noma enwetshwa ngayo. Imichilo ye-COB ingadinga ukucatshangelwa okuhlukile komshayeli, futhi ngenxa yokuthi ivame ukuqukatha iqoqo elikhulu lama-chip, ingadonsa amandla amaningi ngobude beyunithi ngayinye emazingeni aphezulu okukhanya. Ukuqonda lokhu kuhlukanisa okuyisisekelo phakathi kokupakisha nokusatshalaliswa kwama-chip kusiza ukuchaza ukuthi kungani imichilo ye-COB kanye ne-SMD iziphatha ngendlela ehlukile ezinhlelweni zokusebenza zangempela.

Kubaklami nabafaki, ukuqaphela lokhu kuhluka kokukhiqiza kanye nokwehluka kokukhanya kubalulekile. Imichilo ye-SMD inikeza ukuguquguquka, izinketho zombala, kanye nokuguquguquka, kuyilapho imichilo ye-COB iletha ukukhanya okungenamthungo, ukuhlanganiswa okuqinile, kanye nokuqedwa okubonakalayo okusezingeni eliphezulu. Ukwenza ukukhetha okufanele kuncike ekufaniseni lezi zici nezidingo zobuhle nezobuchwepheshe zephrojekthi, ukulinganisela ukukhetha okubonakalayo, izidingo zokusebenza, kanye nesabelomali.

Ikhwalithi yokukhanya, ukuboniswa kombala, kanye nokufana

Ikhwalithi yokukhanya ingumqondo onezici eziningi ohlanganisa izici ezifana nokushisa kombala, inkomba yokunikeza umbala (i-CRI), ukuzinza kombala, kanye nokufana okubonakalayo kokukhanya okukhishwe. Ubuchwepheshe be-SMD kanye ne-COB bobabili bunamandla ezingxenyeni ezahlukene zalolu hlobo. Imichilo ye-SMD ivame ukuvumela abakhiqizi ukuthi balinganise amazinga okushisa ombala kanye nezilinganiso ze-CRI ngokukhetha nokufaka imichilo yamaphakheji e-LED ngamanye. Lokhu kusho ukuthi imichilo ye-SMD ephezulu ye-CRI ingakhiqizwa ukuze ifane eduze nokukhanya kwemvelo kwemisebenzi ebalulekile njengokubonisa imisebenzi yobuciko, ukuthengisa ngokuthengisa, noma izindawo zokusebenza ezizwela umbala. Kodwa-ke, kuye ngokuthi i-SMD ingakanani kanye ne-engeli yokubuka, imichilo ye-SMD ingaveza amaphuzu e-LED ngamanye, okungaholela ekukhanyeni okungalingani kanye nokukhanya okungenzeka uma kusetshenziswa ngaphandle kwe-diffuser.

Ngakolunye uhlangothi, imichilo ye-COB inikeza ukufana okungavamile ngenxa yengqimba yayo ye-phosphor noma ye-resin eqhubekayo emboza i-matrix yama-chips. Ukukhanya kubonakala sengathi kuvela njengebha ebushelelezi, engaphukile, ebaluleke kakhulu ekusetshenzisweni kwezakhiwo nokuhlobisa lapho kudingeka khona umugqa wokukhanya ohlanzekile, ongaphazanyiswa. Lokhu kufana kuvame ukunciphisa izindawo ezishisayo kanye nethunzi, okuthuthukisa ikhwalithi yokukhanya ebonwayo ekusetshenzisweni kokukhanyisa emuva kanye nezici zokugcizelela. I-COB ingabuye yakhelwe amanani ahloniphekile e-CRI, futhi ukwakheka kwe-COB kwanamuhla kungancintisana ne-SMD ngokunemba kombala. Kodwa-ke, ukulawulwa kombala okunemininingwane efana nokuxubana kwe-RGB akuvamile kakhulu ngemichilo ye-COB uma kuqhathaniswa nemichilo ye-SMD ehlanganisa ama-diode ahlukene abomvu, aluhlaza okotshani, naluhlaza okwesibhakabhaka ukuze kukhishwe umbala onamandla.

Ibanga lokubuka kanye nokuba khona kwama-diffuser kuthinta kakhulu ukufana okubonwayo. Lapho ama-strip e-SMD ebekwa ngemuva kwe-diffuser, ikakhulukazi ngama-array e-SMD aqinile, amachashazi abonakalayo angaxutshwa ngokwanele ukuze abonakale eqhubeka. Kuma-strip e-COB, ukusetshenziswa kwama-diffuser kuvame ukuthuthukisa umkhiqizo obushelelezi kakade, okudala ukukhanya okuthambile okufanele ukukhanyisa eshalofini, ukukhanyisa kwe-cove, kanye nezimpawu. Okunye okucatshangelwayo yi-beam angle kanye nokulawula okuqondisayo: Amaphakheji e-SMD avame ukuba nama-optics noma amalensi akhelwe ngaphakathi abumba ukusabalala, okuvumela abaklami ukuthi bahlele ukusabalala kwama-beam ukuze kukhanyise imisebenzi noma imiphumela yokukhanya. Ama-strip e-COB ngokuvamile abanzi futhi asakazeka kakhulu; ngenkathi lokhu kuhle kakhulu ekukhanyeni okulinganayo, kungase kunganikezi isiqondiso esilawulwayo esidingekayo ukuze kugcizelelwe into eyodwa.

Ukuzinza kombala okukhanyayo phakathi nesikhathi sokuphila komkhiqizo nakho kuthinta ikhwalithi yokukhanya okubonakalayo. Imichilo ye-SMD esezingeni eliphezulu enabashayeli abafanele kanye nokuphathwa kokushisa ingagcina umbala nokukhanya okuzinzile amahora amaningi. Imichilo ye-COB, ngenxa yokubekwa kwayo okuxinene kanye nokugqoka okuqhubekayo, ingabonisa nokubukeka kombala okuzinzile kodwa idinga ukwakheka kokushisa okucophelelayo ukuvimbela ukuwohloka kwe-phosphor emazingeni okushisa aphezulu. Ekugcineni, ukukhetha phakathi kwe-SMD ne-COB kuzovame ukuncika ekutheni iphrojekthi ibeka phambili yini ukulawulwa kombala okuhlukile kanye nokuphathwa kokukhanya kwezinga le-fixture (ukuthanda i-SMD) noma ukukhanya okungapheli, okugcizelela ukufana kobuhle (ukuthanda i-COB).

Ukucatshangelwa kokuklama, ukuguquguquka, kanye nokufakwa

Uma ukhetha phakathi kwe-SMD kanye ne-COB LED strips, izidingo zomklamo kanye nokufakwa ngokomzimba zibaluleke kakhulu njengokusebenza kwe-optical. I-SMD strips ngokuvamile i-modular kakhulu futhi iza ngobuningi obuhlukahlukene—ilinganiswa njengenani lama-LED chips ngemitha—ngakho-ke ingalungiswa ukuze ihambisane nemiphumela ehlukene ye-lumen kanye nezikhawu zokusika. I-SMD strips ejwayelekile ivame ukuza nezindawo zokusika ezikhethiwe ngezikhathi ezivamile, okwenza kube lula ukwenza ngokwezifiso futhi kuvumele abafaki ukuthi bakhe ubude obufushane ngaphandle kwezingxenye ezengeziwe. Lokhu kuguquguquka kudlulela ekushintsheni kombala, i-RGB strips enezinjongo eziningi, kanye nezinhlobo ezimhlophe ezilungisekayo, okwenza i-SMD ithandwe ukufakwa okudinga ukuguquguquka kanye nokulungiswa endaweni.

Imichilo ye-COB, yize ifana kakhulu ekukhanyeni, ingaba mnene kakhulu uma kudingeka izinguquko. Ivame ukunikezwa nezindawo ezithile zokusika, kodwa ngenxa yokuthi amachilo agcwele kakhulu futhi uqweqwe luhlanganisa amachilo amaningi, ukusika kumele kwenziwe ezindaweni eziqondile ukuze kugwenywe ukulimaza ukuqhubeka kokukhanya. Amanye amachilo e-COB nawo anobubanzi obuncane bezinketho zemibala uma kuqhathaniswa ne-SMD, ikakhulukazi kusizinda se-RGB, okunganciphisa ukusetshenziswa kwawo ezinhlelweni zokusebenza ezidinga imiphumela yokushintsha umbala. Kodwa-ke, imichilo ye-COB iyaphumelela ekufakweni okuqondile lapho inhloso iwukudala umugqa obonakalayo ongaqhekekile—cabanga ngamakhishi esimanje, ukukhanya kwe-cove yezakhiwo, kanye nokukhanyisa emuva kwezimpawu. Ukubonakala kwawo okuphansi kwamachashazi e-LED ngamanye kuwenza afaneleke ukufakwa eduze kwemigqa yokubona lapho umphumela womthombo wephuzu ungaphazamisa khona.

Izinketho zokufaka kuzo zombili lezi zobuchwepheshe ziyafana ngandlela thile—iziteshi ze-aluminium, iziqeshana, kanye nezinsika ezinamathelayo zivame ukusetshenziswa. Lokho kusho ukuthi, ukusebenza kokushisa kwe-strip kuvame ukunquma indlela yokufaka. Izingcezu ze-SMD eziphumayo kakhulu zivame ukudinga iphrofayili ye-aluminium ukuze zisuse ukushisa futhi zandise isikhathi sokuphila, kuyilapho izingcezu eziningi ze-COB zizuza ngokwemvelo kumaphrofayili afanayo ngenxa yokuhlelwa kwazo okuqinile kwe-chip; kuzo zombili izimo, ukucwilisa ukushisa okufanele kuthuthukisa ubude besikhathi nokuthembeka. Ukuguquguquka kungenye isici sokufaka okufanele usilinganise. Ezinye izingcezu ze-SMD ziguquguquka kakhulu ngoba amaphakheji e-SMD ngamanye mancane futhi anezikhala, okuvumela itheyiphu ukuthi igobe izungeze amajika kalula. Izingcezu ze-COB zingase ziqine kancane ngenxa yokugqoka okuqhubekayo, okunganciphisa ukugoba okubukhali futhi kudinge ukunakwa okwengeziwe lapho kugoqwa amakhona noma kuhambisana nezindawo ezingezona eziqondile.

Ukuhambisana kwamandla nokulawula nakho kuthinta ukukhetha kokufaka. Imichilo ye-SMD enezingxenye ezihlukile ivame ukusekela ukuhlanganiswa okulula nama-dimmer, abalawuli, kanye nezinsiza zikagesi, futhi iziteshi eziningi zemibala zilula ukuzisebenzisa ngentambo ye-RGB noma emhlophe elungisekayo. Imichilo ye-COB ingadinga abashayeli abathile ukuthi baphathe amaphrofayili abo ahlukile wamanje kanye ne-voltage, ikakhulukazi ezinhlotsheni eziphakeme lapho ukudonsa kwamandla ngeyunithi ubude kubalulekile. Ukuqapha nge-wattage, umthamo wokuphakelwa, kanye ne-cable gauge ngesikhathi sokufakwa kuzovimbela ukwehla kwamandla kagesi kanye nokukhanya okungalingani. Ngaphezu kwalokho, indawo yokufaka ibalulekile: ezindaweni zangaphandle noma ezivame umswakama, zombili izinketho ze-SMD kanye ne-COB ziyatholakala ngezimbozo ezingangeni manzi kanye neziteshi ezivikelayo, kodwa indlela yokuvala kanye nokuqina komshini womuchilo okhethiwe kufanele kuhambisane nezimo zokuvezwa.

Ekugcineni, ukwakheka okulungile nokukhetha kokufaka kuncike ekulinganiseni ubuhle, imikhawulo yemishini, kanye nezidingo zikagesi. Uma i-modularity, ukuguquguquka kombala, kanye nokulula kokusika kuyizinto eziza kuqala, i-SMD iyathandeka. Uma ukukhanya okungabonakali, okuqhubekayo kanye nomphumela obonakalayo we-premium kuyizinto ezibaluleke kakhulu, i-COB ivame ukuwina. Ukuhlela okufanele—ukukhetha ubuningi obufanele, umshayeli, isinki yokushisa, kanye nephrofayili yokufaka—kuqinisekisa ukuthi umucu okhethiwe usebenza njengoba kuhlosiwe endaweni eqediwe.

Ukuphathwa kokushisa, ukuqina, kanye nesikhathi sokuphila esilindelekile

Isikhathi sokuphila kanye nokusebenza kwesikhathi eside kwemigqa ye-LED kuthonywa kakhulu ukuphathwa kokushisa kanye nokuqina. Zombili imigqa ye-SMD kanye ne-COB isusa ukushisa lapho isebenza, kodwa ukwakhiwa kwayo kuthonya ukuthi lokho kushisa kungaphathwa kahle kangakanani. Ama-LED e-SMD angamaphakheji ahlukene ahambisa ukushisa nge-die attach kanye nezakhiwo zephakheji ku-substrate ye-PCB. Ukuhlelwa kanye nesikhala salezi zingxenye kuthinta indlela ukushisa okusabalala ngayo kulo lonke i-strip. Imigqa ye-SMD enobukhulu obuphezulu ehlose ukukhipha i-lumen enkulu ngemitha izokhiqiza ukushisa okwengeziwe ngokwemvelo endaweni ehlanganisiwe, ngakho-ke ngokuvamile idinga ukushisa okusebenzayo kakhulu - okuvame ukwenziwa ngeziteshi ze-aluminium noma izinamathiseli zokushisa - ukugcina amazinga okushisa aphansi e-junction nokwandisa isikhathi sokuphila.

Imichilo ye-COB inama-chips afakwe ngqo ku-substrate ngaphansi kwesendlalelo esiqhubekayo esiqhuba ukukhanya. Lokhu kubopha okuseduze kusho ukuthi ukukhiqizwa kokushisa kusatshalaliswa kuma-chips amaningi amancane kanye ne-coating, okungenza ngezinye izikhathi ukushabalalisa ukushisa kube nzima kakhulu uma i-substrate nendlela yokufaka ingavumeli ukudluliselwa kokushisa okuphumelelayo. I-coating eqhubekayo ingasebenza njengesivikelo, ibambe ukushisa ngaphandle kokuthi kusetshenziswe iphrofayili ye-aluminium efanele noma indlela yokushisa. Kuzo zombili izinhlobo, indawo ezungezile kanye nokuhamba komoya okuzungeze ukufakwa kungathinta kakhulu ukusebenza kokushisa. Izikhala ezivalekile ezinomoya omncane zingasheshisa ukwakheka kokushisa futhi zonakalise ukusebenza kahle kokukhanya ngokuhamba kwesikhathi.

Ukuqina kungenye into ebalulekile. Amaphakheji e-SMD LED ngokuvamile aqinile, futhi ngenxa yokuthi ahlanganiswe ngokwawo, ngezinye izikhathi angabekezelela ukucindezeleka komshini kangcono ezimweni ezithile zokufakwa. Kodwa-ke, amajoyinti e-solder kanye nemikhondo ye-PCB kungaba amaphuzu okwehluleka uma i-strip igobeka ngokuphindaphindiwe noma igobile ngaphezu kokubekezelela kwayo okulinganiselwe. Imichilo ye-COB, ene-coating yayo eqhubekayo, inganikeza isivikelo esingcono ekulweni nothuli kanye nokuguguleka okuncane komshini, futhi ivame ukuba namaphuzu ambalwa avelelayo angahluleka ngenxa yokudlidliza noma ukuthinteka. Lokho kusho ukuthi, i-coating ngokwayo ingonakala ngaphansi kokuvezwa isikhathi eside kwezinga lokushisa eliphezulu noma ukukhanya kwe-UV uma ingakhiwanga kahle, okuholela ekushintsheni kwezinga lokushisa lombala noma izici zokusabalalisa.

Ukugcinwa kwe-lumen yesikhathi eside kuyindlela evamile yokulinganisa isikhathi sokuphila. Abakhiqizi bavame ukucacisa inani le-L70—isikhathi esithathayo ukuthi i-strip yehle ibe ngu-70% wokukhanya kwayo kokuqala. Imichilo ye-SMD ne-COB esezingeni eliphezulu ingafinyelela isikhathi sokuphila esibalulekile, ngokuvamile ebangeni lamahora angamashumi ezinkulungwane, kodwa isikhathi sokuphila esiqashelwayo sincike kakhulu ekuphathweni kokushisa, ikhwalithi yomshayeli, kanye nezimo zokusebenza. Abashayeli abahlinzeka ngokulawulwa kwamanje kanye nokuvikelwa kokushisa bandisa impilo ye-LED, kuyilapho abashayeli be-voltage engaguquki abanokulawulwa okubi noma ukwehla okukhulu kwe-voltage ngokuhamba kwesikhathi kungabangela ukuguga okungalingani. Ukungena komswakama kungenye ingozi; ukuvalwa okulinganiselwe yi-IP kanye namasu okuvala afanele kusiza ukugcina imichilo ye-SMD ne-COB ezindaweni ezimanzi noma zangaphandle.

Izinto okufanele uzicabangele ngokunakekela nazo ziyahluka: ukufaka esikhundleni sokusebenza okufushane kwemigqa ye-SMD eguquguqukayo kungaba lula uma izingxenye zenzelwe ukusika nokuxhuma kabusha okulula. Imicu ye-COB ehlanganiswe kumaphrofayili okwakha ingase ibe nzima kakhulu ukuyishintsha uma ifakwe unomphela ngemuva kokuncishiswa noma ifakwe ezindaweni ezifakiwe. Lapho uklama uhlelo oluhloselwe ukuthembeka kwesikhathi eside, hlela ukufakwa okufinyelelekayo futhi ucabangele ukusebenzisa izingxenye namaphrofayili alula ukufaka esikhundleni nokupholisa. Sekukonke, ukunaka ngokucophelela izindlela zokushisa, abashayeli bekhwalithi ephezulu, kanye nokuvikelwa kwemvelo okufanele kwandisa ubude besikhathi somucu we-SMD kanye ne-COB, kodwa indlela engcono kakhulu incike ezicini zomzimba nezokushisa zobuchwepheshe obukhethiwe.

Ukusebenza kahle kwamandla kanye nezici zikagesi

Ukusebenza kahle kwamandla kuyinto ebaluleke kakhulu kumaphrojekthi amaningi okukhanyisa kwe-LED, ikakhulukazi lapho kubalwa izindleko zokusebenza nokukhetha ugesi. Zombili ubuchwepheshe be-SMD kanye ne-COB strip bungasebenza kahle kakhulu uma kuqhathaniswa nokukhanya kwendabuko, kodwa bubhekana nokusebenza kahle ngendlela ehlukile. Ukusebenza kahle kuvame ukuvezwa kuma-lumens nge-watt (lm/W), okulinganisa ukuthi kukhiqizwa ukukhanya okungakanani ku-watt ngayinye esetshenziswayo. Ama-LED e-SMD asezingeni eliphezulu angaklanywa ukuze alethe amazinga e-lm/W amahle kakhulu ngokukhetha izinto ze-semiconductor ezithuthukisiwe, ukwenza ngcono i-chip binning, kanye nokulungisa umklamo we-optical. Ngenxa yokuthi amaphakheji e-SMD ngamanye angaqondiswa ekusebenzeni kahle, abakhiqizi bavame ukunikeza ama-strip e-SMD asebenza kahle kakhulu aklanyelwe izinhlelo zokusebenza ezizwela amandla.

Imichilo ye-COB inganikeza nokusebenza kahle okumangalisayo, ikakhulukazi lapho umklamo ugxile ekunciphiseni ukulahlekelwa kwe-optical kanye nokwandisa inani lama-chip endaweni ngayinye. Ngenxa yokuthi ama-COB anciphisa ukulahlekelwa okuhlobene nama-optical ahlukene kanye nokufaka amalensi azungeze ama-diode ngamanye, ngezinye izikhathi angafinyelela ukufana okuphezulu kwendawo ngokuchitha amandla okubonakalayo okuphansi kuzinhlelo zokusebenza ezithile. Kodwa-ke, ukumbozwa okuqhubekayo kanye nesikhala esiseduze sama-chip kusho ukuthi imichilo ye-COB ingadonsa ugesi omkhulu ngemitha emazingeni aphezulu okukhanya, ngakho-ke okulindelwe yi-wattage kumele kuphathwe ngokucophelela lapho kuhlelwe ukugijima isikhathi eside. Abaklami kumele baqhathanise ukuphuma kwe-lumen nokusetshenziswa kwamandla kwangempela kunokuthembela kuphela ezimangalweni zomkhiqizi.

Izinto ezicatshangelwayo nge-voltage kanye nezintambo zithinta imiphumela yokufaka kanye nokusebenza kahle. Imichilo eminingi ye-LED isebenza kuma-voltage ajwayelekile njenge-12V noma i-24V DC, kanye nezinhlelo ze-24V ezithandwa kakhulu ukuthi zisebenze isikhathi eside ngenxa yokwehla kwamandla kagesi okuncishisiwe kanye nokulethwa kokukhanya okuqhubekayo okuthuthukisiwe. Imichilo enamandla kagesi aphezulu (isb., izinhlobo ze-110V noma ze-220V) nazo zikhona, ezinciphisa inkinga yokwehla kwamandla kagesi kodwa zethula ezinye izinkinga zokuphepha kanye nokufakwa. Igeyiji yokuxhuma, ubude bokusebenza, kanye nokubekwa kwamandla okufaka kunegalelo ekulahlekelweni okunamandla; ukusebenzisa izintambo ezijiyile kanye namandla okufaka ezindaweni eziningi emichilo emide kunganciphisa ukwehla kwamandla kagesi futhi kugcine ukusebenza kahle. Ngenkathi imichilo ye-SMD kanye ne-COB ithintwa ukwehla kwamandla kagesi, imichilo ye-COB emide ingabonisa ukufiphala okubonakalayo ngokuhamba kwesikhathi ngaphandle kokuphathwa kwamandla okufanele ngenxa yokudonsa kwamandla aphezulu.

Izindlela zokunciphisa nokulawula zithinta nokonga amandla. Ngezicucu ze-SMD, ukufiphaza kwe-pulse-width modulation (PWM) kuvame ukusetshenziswa, futhi abashayeli abathuthukile banganikeza ama-dimming curve abushelelezi. Izicucu ze-COB zisabela ngendlela efanayo ekufiphaleni, kodwa ngenxa yokuthi zivame ukuqukethe ama-chip amaningi afanayo, ukunemba kokulawula kwamanje komshayeli kanye nempendulo yokushisa kunquma ukuthi baziphatha kahle kangakanani ngaphansi kokusebenza komjikelezo ophansi. Kusukela embonweni wezinga lesistimu, ukukhetha abashayeli abasebenza kahle kakhulu, ukuqinisekisa ukufana okufanele phakathi kwe-strip voltage kanye nokunikezwa, kanye nokusebenzisa izilawuli ezihlakaniphile (isb., izinzwa zokuhlala, ukuvuna kwasemini, kanye namashejuli ahlelwe) kwandisa izinzuzo zokonga amandla zazo zombili ubuchwepheshe.

Okokugcina, ukubalwa kwezindleko zamandla omjikelezo wokuphila akufanele kufake nje ukusetshenziswa kwamandla okusheshayo kodwa futhi nokugcinwa, imvamisa yokushintsha, kanye nokwehla kokukhanya ngokuhamba kwesikhathi. Ukusebenza kahle kokuqala okuphezulu kungase kungahumushi ukonga isikhathi eside uma ukuphathwa kabi kokushisa kubangela ukwehla kwe-lumen okusheshayo. Ngakho-ke, cabanga ngohlelo lonke—uhlobo lwe-strip, ukusebenza kahle komshayeli, indlela yokufaka, kanye nesu lokulawula—lapho uhlola ukusebenza kwamandla. Zombili izingcezu ze-SMD kanye ne-COB zingasebenza kahle kakhulu uma zichazwe kahle futhi zifakiwe; isihluthulelo ukulinganisela izidingo ezikhanyayo nomklamo nokulawula okufanele kagesi.

Izicelo, izindlela zokukhetha, kanye nezincomo ezisebenzayo

Ukukhetha phakathi kwe-SMD kanye ne-COB LED strips ekugcineni kuncike ezidingweni ezithile zohlelo lokusebenza, imigomo yobuhle, kanye nemikhawulo esebenzayo. Ubuchwepheshe ngabunye buletha amandla ahambisana nezimo zokusetshenziswa ezahlukene. I-SMD strips ifaneleka kahle ekufakweni okudinga ukuguquguquka kombala, imiphumela yokukhanya okuguquguqukayo, kanye ne-modularity. Izibonelo zifaka phakathi izimpawu lapho kudingeka khona imiphumela ye-RGB, izibonisi zokuthengisa ezidinga izinga lokushisa lombala eliguquguqukayo ukuze lifane nemikhiqizo, kanye nokukhanya kwemisebenzi lapho ukukhanya okuqondisiwe kanye ne-CRI ephezulu kuyadingeka khona. Ukulula kokusika nokujoyina i-SMD strips kuzenza zibe yintandokazi yamaphethini okufakwa ngokwezifiso, futhi ukutholakala kwazo ngobuningi obuhlukahlukene kusho ukuthi abaklami bangafanisa ukuphuma kwe-lumen nesidingo ngaphandle kokucacisa ngokweqile.

Imichilo ye-COB ikhanya ezinhlelweni lapho ukukhanya okufanayo nokungenamthungo kubaluleke kakhulu. Ukukhanya kwe-cove yezakhiwo, ukukhanya okungaphansi kwekhabhinethi, ukubhoboza izitebhisi, kanye ne-accent coves kuzuza ngomphumela womugqa oqhubekayo ofihla ama-diode ngamanye. Le michilo ivame ukukhethwa ukuze kufakwe okuveziwe eduze kwemigqa yokubona lapho ukubukeka okungaphazanyiswa kunikela ekubukekeni okuphezulu, kwesimanje. Ukukhanyisa amaphaneli akhanyayo ngemuva nokudala izimpawu ezithambile ezikhanyiswe emaphethelweni, ukuntuleka kwe-COB kwamaphuzu abonakalayo kuholela ekuqedeni okuhle kakhulu. Kodwa-ke, uma kudingeka ukushintsha kombala noma ukulawula okuqondile kwezinga le-pixel, i-COB ingase ingabi yifanele kahle ngaphandle kokuthi kusetshenziswe izinhlobo ezikhethekile.

Izindlela zokukhetha ezisebenzayo zifaka phakathi ikhwalithi yombala, izidingo ze-lumen, ibanga lokubuka, izimo zemvelo, kanye nokufinyeleleka kokugcinwa. Ezindaweni lapho abantu bezoba seduze khona nomugqa—njengaphansi kwamakhabethe ekhishi noma imibukiso yemyuziyamu—ukuphuma okubushelelezi kwe-COB kunciphisa ukukhanya futhi kudala ukukhanya okukhululekile. Ezindaweni ezinkulu ezivulekile noma ukufakwa okudingeka kukhanye ebangeni elide, imichilo ye-SMD enobukhulu obuphezulu enamalensi nama-reflector afanele ingaba yinto engcono kakhulu. Ukucatshangelwa kokufakwa kanye nokubekwa komshayeli kubalulekile: qinisekisa isikhala esanele samaphrofayili e-aluminium kanye nomoya owanele wokungenisa umoya ukuze ugweme izinkinga zokushisa, bese ukhetha abashayeli abanezici ezifanele zokufiphala kanye nokuvikela.

Isabelomali kanye nokucatshangelwa komjikelezo wokuphila nakho kudlala indima. Imichilo ye-SMD ingaba wusizo kakhulu ezinhlelweni eziningi ezivamile futhi ingaba eshibhile ukuyishintsha ekusethweni kwe-modular. Imichilo ye-COB, ikakhulukazi izinhlobo zekhwalithi ephezulu, ingaba ebiza kakhulu ekuqaleni kodwa ingaletha inani eliphakeme lobuhle ekufakweni kwe-premium. Cabanga ngezindleko eziphelele zobunikazi—kufaka phakathi ukusebenza kahle komshayeli, ukusetshenziswa kwamandla, umsebenzi wokufaka, kanye nokugcinwa okulindelekile—kunokugxila kuphela ezindlekweni zangaphambilini.

Okokugcina, uma ucacisa noma yiluphi ubuchwepheshe, cela amashidi edatha anemininingwane kanye nedatha ye-photometric yangempela evela kubakhiqizi. Bheka amanani e-CRI, imiphumela yokuhlolwa kwe-LM79 noma i-LM80, amazinga okushisa okusebenza anconywayo, izilinganiso ze-IP zokusetshenziswa kwangaphandle, kanye neziteshi zokufaka ezinconywayo. Uma kungenzeka, hlola isampula endaweni ukuze uhlole ukuvumelana kombala kanye nokufana ngaphansi kwezimo zokubukwa zangempela. Ukuhlela okucatshangelwe kahle kanye nokunaka izidingo zikagesi, ukushisa, kanye nobuhle kuzoqinisekisa ukuthi ubuchwepheshe be-strip obukhethiwe buletha imiphumela ebonakalayo neyokusebenza ehlosiwe.

Ngamafuphi, lesi sihloko sihlole umehluko oyinhloko phakathi kobuchwepheshe obubili be-LED strip obusetshenziswa kabanzi, sahlola ukuthi busebenza kanjani ngokwekhwalithi yokukhanya kanye nokufana, futhi saxoxa ngezici ezisebenzayo zokuklama, ukuphathwa kokushisa, ukusebenza kahle, kanye nezinhlelo zokusebenza zangempela. Zombili lezi zobuchwepheshe zinikeza izinzuzo ezinengqondo, futhi ukukhetha okuhle kuncike ezintweni ozibeka phambili—kungaba ukubukeka okungenamthungo, ukuguquguquka kombala, ukulula kokufakwa, noma ukusebenza kwamandla kwesikhathi eside.

Njengokucabanga kokugcina, hlola iphrojekthi yakho ngokuphelele: cabanga ngebanga lokubuka kanye nemigomo yobuhle, fanisa ukuphuma kwe-lumen nomsebenzi, beka phambili ukushisa okufanele kanye nezishayeli zekhwalithi, bese uhlela ukufinyeleleka nokuphila isikhathi eside. Ngaleyo ndlela, ungakhetha uhlobo lwe-LED strip oluhlangabezana kangcono nezifiso ezibonakalayo kanye nezidingo ezisebenzayo.
