Zeziphi iindlela ezahlukileyo ezisetyenziselwa ukumitha?

Iindlela ezininzi ziyafumaneka ekukhanyiseni ukukhanya. Ezi ndlela zokuthoba ziyabekwa ngokwamaqela amathathu:

• Ukucuthwa kwamandla ombane (ukuncipha kwamandla): isigaba solawulo
• Umda wesibonakaliso sokulawula (i-analogue): 0-10V, 1-10V
• Ukucekiswa komqondiso wolawulo (yedijithali): I-DALI

Ulawulo lwesigaba

Ukulawulwa kwesigaba yindlela yokufota esekwe kwiifowuni zombane ezihlala zisetyenziselwa iaralogen kunye nezibane ze-incandescent. “Iziqwengana” zenxalenye yamaza esweji yokutshintsha okukhanyayo ukuze kukhanye ukukhanya. Le mizekelo ilandelayo iya kuyenza icace le nto.

Ulawulo lwesigaba esiphambili

Xa inqanaba lisikiwe (okt lilinganiselwe), iivolumu ziya kuhamba kuphela ngexesha elithile emva kokuwela zero (okt wave sine enqumleza oluya ethe tyaba). Yinxalenye yokugqibela yamaza edluliswayo. Eli xesha lokulinda linokugqitywa ngokusebenzisa i-resistor-capacitor elula okanye utshintsho lwedijithali. Le ndlela yokunciphisa ifanelekile kwimithwalo yokutsala / yokutsala (ye-ballast yesiqhelo).

Ulawulo lwecandelo lesiphelo

Ngokulawulwa kwesigaba, i-voltage iyanqunyulwa ngaphambi kokuphela kwesiza samaza ukuze kudluliselwe kuphela icandelo lokuqala. Le ndlela yokuthoba isetyenziselwa imithwalo enika amandla (i-EVSA).

Ulawulo lwesigaba

Ngamanye amaxesha, kokubini okukhokelayo kunye nokulandela umda wesigaba sokulawula kunokwenzeka. Eli nqanaba lidibanisa okukhankanywe ngaphambili:

1-10 V

Ngobuchule be-1 V ubukhulu, umqondiso udluliselwa phakathi kwe-10 V kunye ne-1 V. I-10 yeyona mali iphezulu (10%) ne-100 V yeyona mali isisixa (1%).

0-10 V

Ukuhambisa isibonakaliso phakathi kwe-0 ne-10 V. Ukukhutshwa kwesibane kuncitshisiwe ukuba ivolthi ye-10 V ibonelele nge-100% yokukhanya. Kwaye, i-V V ibonelela ngokuncinci ukukhanya.

DALI

I-DALI imele i-Dilesi yokuKhanyisa yoLwazi lweDijithali. Ngumgangatho wamazwe jikelele ocacisa indlela ufakelo lokukhanya kufuneka lunxibelelane ngolawulo kunye neesistim zokuhambisa.

Kubalulekile ukwazi ukuba i-DALI izimeleyo kubavelisi. Oku kuthetha ukuba kunokwenzeka ukusebenzisa iintlobo ezahlukeneyo zeempawu zenkqubo enye.

Inkqubo nganye inomlawuli kunye nobuninzi bezinto ezikhanyayo ezingama-64, ezifana ne-ballast. Nganye kwezi zinto zinikwa idilesi eyahlukileyo. Umlawuli unokulawula la macandelo kuba inkqubo ye-DALI inokuhambisa kwaye ifumane idatha.

I-DALI ishukumiseka ukusuka kwi-0-100%.

Yakhelwe ngaphakathi imimimitha

Zimbini iintlobo zeemmemer ezakhelweyo: ujikelezo okanye iqhosha lokutyhala.

Isithsithisi esijikeleze idangatye singanyanzelwa ukuba sicime okanye sicime izibane. Ujika iqhosha ukuze ukhethe ubukhulu bokukhanya.

Iqhosha lokutyhala lisebenza ngokungqinelana nomgaqo woku-off. Nangona kunjalo, ukutshintsha ubukhulu bokukhanya, kufuneka ubambe iqhosha. Ezinye iqhosha lokucofa linyibilika kwenye into ekusebenzeni kwazo (ukuqaqamba kuyanda ngexesha lokushicilela okude, ukufiphala kwenzeka ngexesha lomshicileli omde wesibini). Ezinye ii-switch zemmers zokucofa zifikelela ipesenti ethile (ukuqaqamba kokuqaqamba ukuya kubungakanani obuthile xa ipesenti eyi-N ifikile kwaye iphinda iphinde).
