Ama-PCB e-LED Downlight: Izinjini Zokukhanya Eziyindilinga, Abashayeli kanye Namabhodi Okufiphaza Ama-Fixtures Avaliwe

Ukukhanya okuphansi kuyinkambiso yokukhanya kwangaphakathi kwesimanje — okufakwe ophahleni emakhaya, emahhovisi, emahhotela, ezitolo, nasemakliniki ngezinkulungwane. Kubukeka kulula, kodwa amabhodi amabili anquma ukuthi ukukhanya okuphansi kuyinto ejabulisayo noma inkinga: injini yokukhanya eyindilinga ephethe ama-LED, kanye nomshayeli owasebenzisa amandla futhi awafiphaze. Lapho ukukhanya okuphansi kuduma, kuphazima, noma kwenqaba ukufiphaza ngeswishi yodonga esivele ikhona ekamelweni, imbangela cishe njalo ingenye yalawo mabhodi amabili.

I-Highleap Electronics iyifektri yokukhiqiza amabhodi wesekethe anekhono eliphelele kanye nefektri yokuhlanganisa amabhodi wesekethe aphrintiwe , futhi izinjini zensimbi eziyinhloko kanye nabashayeli abancane abadingwa yizibani ze-downlight kuwumsebenzi wansuku zonke emigqeni yethu. Sakha amabhodi womabili futhi siwahlanganise abe yimojuli ehambisanayo. Lo mhlahlandlela uhlanganisa lokho okwenza ibhodi le-downlight libe lihle - ikakhulukazi ukuziphatha okufiphele okubonwa yiwo wonke umuntu - nokuthi unga-oda kanjani. Isigaba esibanzi sisekhasini lethu lomkhiqizi webhodi yesekethe yokukhanyisa.

Impendulo esheshayo: Isibani esiphansi sidinga injini yokukhanya yensimbi eyindilinga (noma eyisikwele) kanye nomshayeli wamandla aqhubekayo ahambisanayo, futhi ukuhlanganisa kumele kufiphale kahle futhi kungabi nokufiphaza nge-dimmer yesakhiwo. I-Highleap Electronics yakha futhi ihlanganise amabhodi womabili ndawonye — izinjini ze-aluminium MCPCB kanye nabashayeli abalungiselelwe i-TRIAC, 0-10 V, noma i-DALI dimming — ngakho-ke i-fixture ifiphale kahle iye emazingeni aphansi, ku-MOQ 1 ngesilinganiso samahora angama-24.

Amabhodi amabili ngaphakathi kokukhanya ngakunye

Isibani esiphansi siyindlela elula kunazo zonke yokukhanyisa amabhodi amaningi, kodwa kuseyisimiso samabhodi amabili okumele afaniswe. Injini yokukhanya — i -PCB eyindilinga noma eyisikwele yensimbi ephethe ama-LED — isetha ikhwalithi yokukhanya futhi ilawula ukushisa. Umshayeli uguqula amandla amakhulu abe ugesi oqhubekayo odingwa yinjini futhi unikeza isikhombikubona sokufiphala. I-fixture isebenza kahle kuphela uma lezi ezimbili zakhiwe ndawonye.

Lokho kufanisa kuyiwona mdlalo wonke. Umshayeli ojwayelekile oboshelwe enjinini eyenziwe ngokwezifiso uvame ukufiphala kabi, asebenzise ama-LED kugesi ongafanele, noma aqhume. Lapho umenzi ofanayo akha womabili, ugesi wokukhipha womshayeli usethelwe ku-LED array enjinini, futhi ukufiphala kulungiselelwa lowo mthwalo — yingakho umbhangqwana ohambisanayo usebenza nje lapho ongafani udumaza khona.

Izinjini zokukhanya eziyindilinga neziyisikwele zemishini evaliwe

Izinjini zokukhanyisa phansi zingamabhodi amancane lapho ikhwalithi yombala, ukushisa, kanye nendawo yomthombo kubalulekile khona. Sizakha emgqeni wethu we -aluminium LED PCB ukuze indawo yokuhlangana kwe-LED ihlale ipholile futhi umbala uhlale uzinzile ethini elivaliwe elivalekile:

• Amafomethi ayindilinga nesikwele — ubukhulu bayo bube ububanzi bokukhanya okuphansi, kanye ne-LED array ephakathi nendawo ye-reflector noma ilensi.
• SMD ama-array aphakathi kwamandla — kokukhanya okulinganayo, okukhululekile okunemibala emihle, ukukhetha okuvame kakhulu kokukhanya okuphansi.
• Izinketho ze-High-CRI — I-CRI 90+ yezitolo, izihambi, kanye nezindawo zokuhlala lapho kuthengiswa khona imibala egqamile.
• Imaski emhlophe ekhanyisa kakhulu — ukusunduza ama-lumen asebenzisekayo ebhodini nangaphandle kwe-fixture.
• Okumhlophe okucwebezelayo — izinjini zeziteshi ezimbili zezinto ezishintsha izinga lokushisa lombala, ezakhiwe ngokulawula okufanayo.

Injini ifaniswe nosayizi wethini, i-optic, kanye nekhwalithi yokukhanya okuthenjiswa yi-fixture — hhayi ibhodi elilodwa eliphoqelelwe kuzo zonke izindlu.

Ukuhambisana okufiphele kanye nomklamo ongenawo ama-flash

Ukufiphala kwe-light kuyinto evame kakhulu ukukhononda ngokukhanya okuphansi, futhi kufanelekile ukuqonda ukuthi kungani, ngoba yilapho ibhodi lomshayeli elakhiwe kahle lithola khona imali yalo. Izinkinga abantu ababhekana nazo - ukukhanya okuphuma phansi kwe-dial, okufiphazayo, okudumayo, noma okungeke kufiphale nhlobo ngeswishi ekhona - cishe konke kungokwesomshayeli, futhi cishe konke kungagwenywa.

Inkinga yokuhambisana. Iningi lama-dimmer akhona emakhaya nasezindaweni ezincane zezentengiselwano yi-phase-cut (TRIAC) dimmers ekuqaleni eyenzelwe imithwalo ye-incandescent yama-watts angamakhulu ambalwa. Isibani se-LED sidonsa ingxenye encane yalokho, kanti i-LED driver eshibhile inikeza umthwalo i-dimmer endala engakwazi ukuwufunda kahle - ngakho-ke iyathuthumela, iyaphazima, noma inobubanzi obuncane obusebenzisekayo. I-driver eyenzelwe ukuhambisana kwe-phase-cut ifaka phakathi i-circuitry yokuveza umthwalo ozinzile, onobungane ne-dimmer kulo lonke ububanzi:

• I-Bleeder kanye ne-damping circuitry ngakho-ke i-TRIAC idubula ngokwethembeka ngisho noma i-LED idonsa amandla aphansi.
• Ukuhambisana kwe-Wide dimmer — ihlolwe ngokumelene nezinhlobo ezivamile ze-dimmer umfaki angase ahlangane nazo, ngakho-ke i-fixture isebenza ngamaswishi asevele esodongeni.
• I-low-end ebushelelezi — ububanzi bokufiphala okujulile (kuya ku-10%, 1%, noma ngaphansi) ngaphandle kokuyeka noma izinyathelo ezibonakalayo.

Inkinga yokufiphaza. Ukufiphaza kugcwele kugesi we-LED, futhi kubalulekile enduduzo kanye nasempilweni namavidiyo. Abanye abantu baphathwa yikhanda ngaphansi kokukhanya okufiphaza; amakhamera akubonisa njengokubhanqa. Umshayeli omuhle ugcina ukufiphaza kuphansi (iphesenti lokufiphaza kanye nenkomba yokufiphaza kulawulwa) ngokulawula kahle amandla kagesi we-LED, futhi ukukhethwa kokulungiswa kwe-LED yenjini ukuze umshayeli akwazi ukwenza lokho ngempumelelo:

• Iphesenti eliphansi lokuphazima kulo lonke ububanzi bokufiphala, hhayi nje kuphela lapho kuphuma khona ngokugcwele lapho kulula khona.
• Umbala ohlala njalo ngenkathi ufiphala — umbala ubambeke uqinile njengoba ukuphuma kwehla, okuyinto amasekethe ashibhile okufiphaza ahluleka ukuyenza.
• Ukukhetha kwephrothokholi — kumaphrojekthi ezentengiselwano, ukufiphaza okungu-0-10 V noma i-DALI kugwema ngokuphelele inkinga yokuhambisana nokunqunywa kwesigaba, futhi sakha abashayeli balezo zixhumi.

Isizathu sokuthi lokhu kuyinkinga yokuklama ibhodi hhayi inkinga yokuhlanganisa i-luminaire ukuthi ukuhambisana kwe-flicker ne-dimmer kunqunywa yi-topology yomshayeli kanye nomthwalo we-LED ohambisana nawo. Lapho umenzi oyedwa akha umshayeli kanye nenjini ndawonye futhi elungisa ukufiphala ku-LED array yangempela, i-fixture iyafiphala ngendlela amakhasimende ayilindele. Uma ivela kubahlinzeki abahlukene, "ayifiphali kahle" iba umsebenzi wokukhomba ngomunwe ongenamnikazi. Ukwakha womabili amabhodi endaweni eyodwa kuyindlela ewusizo yokubuyisela ukukhanya okuvamile.

Amafomethi omshayeli: ahlanganisiwe, akude, kanye nemodyuli

Izibani eziphansi zipakisha umshayeli ngezindlela ezahlukene kuye ngokuthi iyiphi into efakiwe, futhi sakha amabhodi omshayeli ngamunye:
