Uhlolojikelele lomthombo wokukhanya we-chip yesibani somgwaqo we-LED kanye nomthombo wokukhanya wokushintsha

Uhlolojikelele lomthombo wokukhanya we-chip yesibani somgwaqo we-LED kanye nomthombo wokukhanya oshintshayo 1. Umthombo wokukhanya wohlobo lwe-Chip Uhlobo lokufaka iphinikhodi engu-1 (DIP) Lobu buhlalu besibani se-LED buyi-diode ekhipha ukukhanya enesakhiwo esilula, ngoba kunemicu emibili emise okwe "izinyawo" ngaphansi kobuhlalu besibani, obungaxhunywa ngokuqondile ebhodini lesifunda. Ngakho kubizwa ngokuthi ubuhlalu besibani obufakwe uphini. Inokuphepha okuhle, ukusebenza okuzinzile, ingakhipha ukukhanya ngaphansi kwezimo zamandla kagesi aphansi, futhi inokulahlekelwa okuphansi, ukusebenza kahle okuphezulu, impilo ende, futhi ingenza nokufiphalisa ngemibala eminingi. Amajamo ajwayelekile: Lolu hlobo lobuhlalu besibani lungaba nezimo ezihlukahlukene, njengeziyindilinga, eziyisiyingi, eziyisikwele, ngisho nezimise okukhethekile.

Nakuba sikhuluma ngokulingana, awukho umehluko omkhulu ekubunjweni nasekusayizini, kodwa izigaba eziphambanayo zobumo obuhlukene zobuhlalu bezibani zihlukile. Uhlobo olukhanyayo: Uma ubheka ubuhlalu besibani obuhlukene ngokucophelela, uzothola ukuthi inani "lezikhonkwane" zobunye ubuhlalu besibani lihlukile, futhi lezi "zikhonkwane" zingenza ama-diode akhipha ukukhanya akhiqize ukukhanya kwemibala ehlukene. Izinkambu zokufaka isicelo: Emkhakheni wokukhanyisa, ubuhlalu besibani be-plug-in abusetshenziswa neze; ngokuvamile asetshenziswa kakhulu njengamalambu emoto, amalambu ezinkomba, izikrini zokubonisa, njll.

Umthombo wokukhanya wobuhlalu obuphezulu obunamandla aphansi (SMD) uthengisa ama-diode akhipha ukukhanya ebusweni bebhodi lesifunda esikhundleni sokudlula ebhodini lesekethe. Incane ngosayizi, kanti eminye mincane kunobuhlalu besibani obufakwe ngophini. Amamodeli avamile: Kunamamodeli amaningi alolu hlobo lobuhlalu bezibani, okuvame ukusetshenziswa kakhulu ngu-2835 (PCT), 4014, 3528, 3014, njll. Izinombolo ezimbili zokuqala zenombolo ngayinye yemodeli zibonisa ububanzi "x.xmm", futhi amadijithi amabili okugcina abonisa ubude "xx mm".

Isibonelo, i-2835 imele ububanzi obungu-2.8 mm nobude obungu-3.5 mm. Ingaphezulu limbozwe ngempushana ye-fluorescent ephuzi futhi ikhipha ukukhanya okumhlophe. Izinkambu zohlelo lokusebenza: Lolu hlobo lobuhlalu besibani obubekwe phezulu obunamandla aphansi lungasetshenziswa ebangeni elibanzi kakhulu. Ngenxa yobukhulu bayo obuncane, ingasetshenziswa noma kuphi, ngakho-ke inganamathiselwa ezibanini ezihlukahlukene ze-LED, futhi ubuningi bungashintshwa futhi bushintshwe ngokuvumelana nezidingo.

Uhlobo lwesithathu lobuhlalu bezibani ezibekwe phezu kwamandla aphezulu lubuye lube uhlobo olubekwe phezulu, olufana ngokwemvelo nobuhlalu bezibani ezisezingeni eliphansi lamandla aphansi, ngaphandle kokuthi amandla aphezulu kanye nevolumu kukhulu; ngokwesakhiwo esihle, kune-lens eyengeziwe, engakwazi Ukukhanya kuhlangana kangcono. Izinhlobo ezivamile: Kukhona futhi izinhlobo eziningi zobuhlalu bezibani ezibekwe phezu kwamandla aphezulu: uma umbala ongaphezulu wobuhlalu besibani uphuzi, ngokuvamile unokushisa kombala ophansi; uma umbala ongaphezulu uluhlaza okotshani, ngokuvamile izinga lokushisa lombala eliphezulu; uma ingekho i-phosphor, ubuhlalu besibani abunambala futhi busobala, ngokuvamile bunombala okhanyayo. Inkambu yokusetshenziswa: Lolu hlobo lobuhlalu bezibani ngokuvamile lusetshenziswa ngemva kokufakwa kwilensi (ukwenza kube lula ukuhlangana noma ukuhlakazeka kokukhanya), futhi ngokuvamile lwenziwa kube izibani nezibani.

Olunye uhlobo lwephakheji edidiyelwe (COB) ubuhlalu besibani obuhlanganisiwe obuhlanganisiwe, obupakisha ama-chips amaningi obuhlalu besibani ebhodini elifanayo, futhi usayizi uyafana nobubanzi bohlamvu lwemali lwamasenti angu-50. Izimo ezivamile ngokuvamile zihlanganisa nxazonke, umcu kanye nesikwele, futhi amabhodi ahlanganisiwe amise okwe-strip avame ukusetshenziswa njengezibani zedeski. 2. Umthombo wokukhanya wokubuyisela esikhundleni se-LED uwumthombo wokukhanya ojwayeleke kakhulu osuselwe kubuhlalu besibani.

Okokuqala, ubuhlalu bezibani zezibani ze-LED zomgwaqo zingenziwa zibe ama-bulb ahlukahlukene, angafaniswa ne-interfaces yamandla endabuko futhi ashintshwe ngokuthanda kwakhe. Izinkambu zokufaka isicelo: Incazelo esobala iwukuthi ingashintsha isibani sokuqala se-halogen noma isibani se-incandescent (ukusetshenziswa kwamandla okuphansi, ukukhanya okuphezulu kokukhanya); ingasetshenziswa futhi njenge-bulb yama-chandelier, izibani zokuhlobisa, izibani eziphansi, izibani eziqeqeshiwe, njll. Amamodeli avamile: amapheshana akhanyayo Enye imichilo yokukhanya, engahlukaniswa ibe yimichilo yokukhanya eqinile kanye nemichilo yokukhanya ethambile, engashintsha izibani zokuqala ze-T5 Fluorescent.

Izici: I-strip yokukhanya ithambile, incane ngosayizi, iyalungiseka ekukhanyeni, ingasikwa futhi ixhunywe ngokuthanda; eqinile epulasitiki, kulula ukwenza ubujamo kanye nama-contours shape.Izinkambu zokufaka isicelo: Amashubhu okukhanya e-LED angabonakala ezikoleni, emahhovisi, ezitolo ezinkulu nakwezinye izindawo.
