Kukhona uhla olubanzi kakhulu lweI-DALI inikwe amandla imikhiqizo yokulawula ukukhanyaitholakala kubo bonke abakhiqizi abahamba phambili futhi manje seyaziwa kabanzi njengendinganiso yomhlaba wonke yokulawula ukukhanya.

Izici ezibalulekile ze-DALI:

• Iphrothokholi evulekile - noma yimuphi umkhiqizi angayisebenzisa.
• Ukusebenzisana kwe-DALI-2 phakathi kwabakhiqizi kuqinisekiswa izinqubo zokuqinisekisa eziphoqelekile.
• Ukufaka kulula.Izintambo zamandla nokulawula zingabekwa ndawonye futhi akukho ukuvikela okudingekayo.
• I-topology yezintambo ingaba sesimweni senkanyezi (ihabhu & ekhuluma), isihlahla noma umugqa, noma iyiphi inhlanganisela yalokhu.
• Ukuxhumana kungokwedijithali, hhayi i-analogue, ngakho amanani afana ncamashi okufiphalisa angatholwa amadivayisi amaningi okuholela ekusebenzeni kokufiphaza okuzinze kakhulu nokunembayo.
• Wonke amadivaysi anekheli lawo eliyingqayizivele ohlelweni evula amathuba abanzi kakhulu okulawula okuguquguqukayo.

I-DALI IQHATHANISWA KANJANI NE-1-10V?

I-DALI, njenge-1-10V, yakhelwe futhi imboni yokukhanyisa.Izingxenye zokulawula izibani, ezifana nezishayeli ze-LED nezinzwa, zitholakala kuhlu lwabakhiqizi abane-DALI ne-1-10V interfaces.Nokho, kulapho ukufana kuphela khona.

Umehluko omkhulu phakathi kwe-DALI ne-1-10V yile:

• I-DALI iyaphenduleka.Lokhu kuvula indlela yezici eziningi ezibalulekile njengokuhlanganisa, ukuhlela indawo kanye nokulawula okuguquguqukayo, njengokushintsha ukuthi yiziphi izinzwa namaswishi alawula ukuthi yikuphi ukufakwa kokukhanya ekuphenduleni izinguquko zesakhiwo sehhovisi.
• I-DALI iyidijithali, hhayi i-analogue.Lokhu kusho ukuthi i-DALI inganikeza ukulawula izinga lokukhanya okunembe kakhudlwana kanye nokufiphala okungaguquki.
• I-DALI iyindinganiso, ngakho-ke, ngokwesibonelo, ijika lokufiphala lilinganiselwe okusho ukuthi okokusebenza kuyasebenzisana phakathi kwabakhiqizi.Ijika lokufiphalisa elingu-1-10V alikaze lifane, ngakho-ke ukusebenzisa izinhlobo ezihlukene zabashayeli esiteshini sokufiphala okufanayo kungaveza imiphumela engahambisani kakhulu.
• I-1-10V ingalawula kuphela ukuvula/ukuvala kanye nokufiphalisa okulula.I-DALI ingaphatha ukulawulwa kombala, ukushintsha umbala, ukuhlolwa kwezibani eziphuthumayo kanye nempendulo, ukusethwa kwesigameko okuyinkimbinkimbi neminye imisebenzi eminingi eqondene nokukhanya.

INGABE BONKEImikhiqizo ye-DALIIYAQHUBANA NOMUNYE?

Ngenguqulo yasekuqaleni ye-DALI, kube nezinkinga zokusebenzisana ngoba ukucaciswa bekunomkhawulo impela kububanzi.Uhlaka lwedatha lwe-DALI ngalunye lwalungamabhithi angu-16 kuphela (amabhithi angu-8 ekheli kanye namabhithi angu-8 omyalo), ngakho inani lemiyalo etholakalayo lalilinganiselwe kakhulu futhi kwakungekho ukutholwa kokushayisana.Ngenxa yalokho, abakhiqizi abaningana bazama ukwandisa amakhono abo ngokwenza izengezo zabo, okuholele ekungahambelani okuthile.

Ngokufika kwe-DALI-2 lokhu kunqotshiwe.

• I-DALI-2 izimisele kakhulu kububanzi bayo futhi iqukethe izici eziningi ebezingekho enguqulweni yokuqala.Umphumela walokhu ukuthi izengezo ezenziwa abakhiqizi ngabanye ku-DALI azisabalulekile.Ukuze uthole incazelo eningiliziwe yezakhiwo ze-DALI-2, sicela uye kokuthi “Isebenza kanjani i-DALI”, ngezansi.
• Ilogo ye-DALI-2 ingeye-DiiA (i-Digital Illumination Interface Alliance) futhi banamathisele imibandela eqinile ekusetshenzisweni kwayo.Okuyinhloko phakathi kwalokhu ukuthi awukho umkhiqizo ongaphatha ilogo ye-DALI-2 ngaphandle uma wenze inqubo ezimele yesitifiketi ukuze uhlole ukuthobela ngokugcwele kwe-IEC62386.

I-DALI-2 ivumela ukusetshenziswa kwazo zombili izingxenye ze-DALI-2 ne-DALI ekufakweni okukodwa, kuncike emikhawulweni ethile.Eqinisweni, lokhu kusho ukuthi abashayeli be-DALI LED (njengesibonelo esiyinhloko) bangasetshenziswa ekufakweni kwe-DALI-2.

USEBENZA KANJANI UDALI?

Umnyombo we-DALI yibhasi – izintambo ezimbili ezithwala amasiginali okulawula idijithali zisuka kumadivayisi okufakwayo (njengezinzwa), ziye kusilawuli sohlelo lokusebenza.Isilawuli sohlelo lokusebenza sisebenzisa imithetho esihlelelwe ngayo ukukhiqiza amasiginali aphumayo kumadivayisi afana namashayeli e-LED.

• Iyunithi yokuphakelwa kwamandla webhasi (PSU).Le ngxenye ihlale idingeka.Igcina i-voltage yebhasi ezingeni elidingekayo.
• I-Led Fittings.Konke ukufakwa kokukhanya ekufakweni kwe-DALI kudinga umshayeli we-DALI.Umshayeli we-DALI angamukela imiyalo ye-DALI ngokuqondile ebhasini le-DALI futhi aphendule ngokufanele.Abashayeli bangaba amadivaysi e-DALI noma e-DALI-2, kodwa uma bengewona i-DALI-2 ngeke babe nezinto ezintsha ezethulwe ngale nguqulo yakamuva.
• Amadivayisi okokufaka - izinzwa, amaswishi njll. Lezi zixhumana nesilawuli sohlelo lokusebenza zisebenzisa amafreyimu wedatha angama-24-bit.Abaxhumani ngokuqondile namadivayisi okulawula.
• Izimo.Ngokuvamile, idivayisi efana nenzwa izoqukatha inani lamadivayisi ahlukene ngaphakathi kwayo.Isibonelo, izinzwa zivame ukufaka umtshina wokunyakaza (PIR), umtshina weleveli yokukhanya kanye nesamukeli se-infra-red.Lezi zibizwa ngezimo - idivayisi eyodwa inezimo ezi-3.Nge-DALI-2 isibonelo ngasinye singaba seqembu elihlukile lokulawula futhi ngasinye singasingathwa ukuze silawule amaqembu ahlukene okukhanyisa.
• Lawula amadivayisi – isilawuli sohlelo lokusebenza.Isilawuli sohlelo lokusebenza "ingqondo" yesistimu.Ithola imilayezo engu-24-bit evela kuzinzwa (njll) futhi ikhiphe imiyalo engu-16-bit egiyeni lokulawula.Isilawuli sohlelo lokusebenza siphinde silawule ithrafikhi yedatha ebhasini le-DALI, sibheka ukushayisana futhi siphinde sikhiphe imiyalo njengoba kudingeka.

Imibuzo Evame Ukubuzwa

• Yini umshayeli we-DALI?Umshayeli we-DALI ungumshayeli we-LED ozokwamukela okokufaka kwe-DALI noma kwe-DALI-2.Ngaphezu kwamatheminali ayo abukhoma futhi angathathi hlangothi izoba namatheminali amabili engeziwe abhalwe ukuthi DA, DA yokunamathisela ibhasi le-DALI.Abashayeli besimanje be-DALI baphethe uphawu lwe-DALI-2, okubonisa ukuthi bangaphansi kwenqubo yokuqinisekisa edingwa izinga lamanje le-IEC.
• Kuyini ukulawula kwe-DALI?Ukulawulwa kwe-DALI kubhekisela kubuchwepheshe obusetshenziswa ukulawula ukukhanya.Obunye ubuchwepheshe bukhona, ikakhulukazi i-0-10V kanye ne-1-10V, kodwa i-DALI (kanye nenguqulo yayo yakamuva, i-DALI-2) iyindinganiso eyamukelwa umhlaba wonke yokulawula izibani zentengiso.
• Uyihlela kanjani idivayisi ye-DALI?Lokhu kuyahlukahluka kumkhiqizi oyedwa kuya komunye futhi ngokuvamile kuzobandakanya izinyathelo ezimbalwa.Esinye sezinyathelo zokuqala sizohlala siwukunikeza ikheli kudivayisi ngayinye ekufakweni.Ukuhlela kungenziwa ngaphandle kwentambo nabanye abakhiqizi kodwa okunye kuzodinga uxhumano lwezintambo ebhasini le-DALI.
