• Ukuhambisana nesondlo Ukuze uhlelo lwe-DALI lusebenze, kufanele wenze isizindalwazi esixhumanisa amakheli e-LED nezilawuli ezifanele. Ukuze lezi zinhlelo zisebenze kahle kakhulu, kufanele uwakhe futhi uwagcine esesimweni esihle.
• Zibekele wena ngokwakho Kungase kubonakale sengathi i-DALI ingumqondo olula ukuwuqonda ngokombono. Kodwa awukwazi ukukumisa uwedwa. Njengoba ukuklama, ukufakwa, kanye nezinhlelo kuyinkimbinkimbi, Ngakho-ke, uzodinga isifaki esinguchwepheshe.

I-DALI inesikhathi esingakanani ikhona?

Umlando we-DALI uyajabulisa. Umbono wangempela walokhu uvela kubakhi be-ballast baseYurophu. Inkampani yokuqala ye-ballast yasebenza nabanye abathathu ukuphakamisa ukuthi i-International Electrotechnical Commission (IEC) yenze izinga lokuthi ama-ballast akhuluma kanjani omunye nomunye. Phakathi kwakho konke, ngasekupheleni kwawo-1990, i-United States nayo yahileleka.

U-Pekka Hakkarainen, umqondisi wezobuchwepheshe nokuthuthukiswa kwebhizinisi kwaLutron Electronics e-Coopersburg, PA, kanye nosihlalo we-Lighting Controls Council ku-National Electrical Manufacturers Association e-Rosslyn, VA, uthi izinga liyingxenye yezinga le-IEC lamabhola e-fluorescent futhi esinye sezijobelelo ezijwayelekile (NEMA). Isethi yemithetho yokuxhumana ne-ballast eyamukelwa ngokuvamile inikezwa.

Ngasekupheleni kwawo-1990, abashayeli bokuqala be-DALI LED kanye nama-ballasts baphuma e-United States. Ngo-2002, i-DALI yayisiyindinganiso emhlabeni wonke.

Imibuzo Evame Ukubuzwa

Isifinyezo

I-DALI ayibizi futhi kulula ukuyishintsha ukuze ivumelane nezimo ezahlukahlukene. Lolu hlelo lokukhanyisa luhle kakhulu kumabhizinisi ngoba ungalulawula usendaweni eyodwa. Isebenza njengohlelo lokukhanyisa olulula kuzo zombili izakhiwo ezintsha nezindala. I-DALI yenza kube nokwenzeka ukuthola izinzuzo zezilawuli zokukhanyisa okungenantambo. Izinzuzo ezifana nokwenyuka kokusebenza kahle, ukuhambisana namakhodi wokwakha. Futhi ikhono lokusebenza nezinye izinhlelo, kanye nekhono lokuhlangabezana nezidingo ezahlukene zokukhanyisa.

Isistimu yokufiphalisa ye-DALI iqinisekisa ukuthi ukukhanya kwakho kuyasebenza futhi kuyajabulisa ukukubuka.
