Yiziphi izindlela ezahlukahlukene ezisetshenziselwa ukufiphaza?

Izindlela eziningana ziyatholakala ukukhanyisa ukukhanya. Lezi zindlela zokufiphaza zihlukaniswe ngamaqembu amathathu:

• Ukunciphisa amandla kagesi (ukuncipha kwamandla): isigaba sokulawula
• Ukunciphisa isignali yokulawula (i-analogue): 0-10V, 1-10V
• Ukunciphisa isignali yokulawula (eyedijithali): DALI

Ukulawulwa kwesigaba

Ukulawulwa kwesigaba kuyindlela yokufiphaza esekelwe ocingweni kagesi ovame ukusetshenziselwa izibani ze-halogen namalambu we-incandescent. I "isiqeshana" ingxenye yamaza omugqa we-alternating yamanje ukuze kukhanye ukukhanya. Izibonelo ezilandelayo zizokwenza kucace lokhu.

Ukuhola kwesigaba sokuhola

Lapho isigaba sisikiwe (okusho ukuthi sinqunyelwe), i-voltage izogeleza kuphela ngesikhathi esithile ngemuva kokuwela zero (okusho i-sine wave ewela i-eksisi evundlile). Ingxenye yamuva yensimbi kuphela edluliswa. Lesi sikhathi sokulinda singanqunywa kusetshenziswa i-resistor-capacitor elula noma ukushintshwa kwedijithali. Le ndlela eguquguqukayo ilungele imithwalo eholela futhi evuselelayo (i-ballast yendabuko yendabuko).

Ukulawulwa kwesigaba somkhawulo

Ngokulawulwa kwesigaba, i-voltage iyanqunywa ngaphambi kokuphela kokugudlwa kwe-sine ukuze kuphela ingxenye yokuqala idluliselwe. Le ndlela yokufiphaza isetshenziselwa imithwalo ye-capacitive (EVSA).

Ukulawulwa kwesigaba

Kwesinye isikhathi, zombili izindlela eziholayo nezihola umkhawulo kulayini kungenzeka. Lokhu kugagasi kuhlanganisa okungenhla:

1-10 V

Ngenqubo ye-1 V yokufiphaza, isiginali idluliselwa phakathi kuka-10 V no-1 V. 10 V inani eliphakeme (10%) kuthi u-100 V inani eliphansi (1%).

0-10 V

Idlulisa isiginali phakathi kuka-0 no-10 V. Ukukhishwa kwesibani kukhishwa ngendlela yokuthi amandla kagesi ayi-10 V anikezela ngokukhanya okungu-100%. Futhi, u-0 V unikeza okukhanyisa okuncane kakhulu.

DALI

I-DALI imele i-Digital Addressable Lighting Interface. Kuyindlela yamazwe omhlaba echaza ukuthi ukufakwa kokukhanyisa kufanele kuxhumana kanjani nezinhlelo zokulawula nokuqondisa.

Okubalulekile ukwazi ukuthi i-DALI izimele abakhiqizi. Lokhu kusho ukuthi kungenzeka ukusebenzisa izinhlobo ezahlukene zezakhi ohlelweni olufanayo.

Uhlelo ngalunye luqukethe isilawuli kanye nenani lezinto ezikhanyayo ezingama-64, njenge-ballast. Ngayinye yalezi zingxenye inikezwa ikheli elihlukile. Isilawuli singalawula lezi zingxenye ngoba uhlelo lwe-DALI lungadlulisa futhi lwamukele idatha.

I-DALI iyabonakala kusuka ku-0-100%.

Amamimitha akhelwe ngaphakathi

Kunezinhlobo ezimbili zama-dimmers ezakhelwe ngaphakathi: inkinobho yokujikeleza noma yokucindezela.

Isimbotshana senduku esingaguqukayo singacindezelwa ukuvula noma ukucisha izibani. Uvula imvu ukuze ukhethe ubukhulu bokukhanya.

Inkinobho yokucindezela isebenza ngokuya ngomgomo ofanayo ocishiwe. Noma kunjalo, ukuze ushintshe ubukhulu bokukhanya, kufanele ubambe inkinobho. Ezinye inkinobho zokucindezela ziguquguquka ekusebenzeni kwazo (ukugqama kuyanda ngesikhathi sokushicilelwa okude kokuqala, ukufiphala kwenzeka ngesikhathi sokushicilela eside lesibili). Amanye ama-inkinobho we-push dimmers afinyelela iphesenti elithile (ukugqama kuyanda kufinyelela kuthile lapho iphesenti le-N lifinyelelwa bese iphinda ithambe).
