Kukho uluhlu olubanzi kakhulu lweI-DALI yenza iimveliso zokulawula ukukhanyaifumaneka kubo bonke abavelisi abakhokelayo kwaye ngoku yamkelwa ngokubanzi njengomgangatho wehlabathi wolawulo lokukhanyisa.

Iimpawu eziphambili ze-DALI:

• Yiprotocol evulekileyo - nawuphi na umenzi unokuyisebenzisa.
• Nge-DALI-2 ukusebenzisana phakathi kwabavelisi kuqinisekiswa ngeenkqubo zokuqinisekisa iziqinisekiso.
• Ukufakela kulula.Amandla kunye nemigca yokulawula inokubekwa kunye kwaye akukho khuselo lufunekayo.
• I-wiring topology ingaba kwimo yeenkwenkwezi (hub & spoke), umthi okanye umgca, okanye nayiphi na indibaniselwano yezi.
• Unxibelelwano lwedijithali, hayi i-analogue, ngoko ke amaxabiso afanayo okufiphala angafunyanwa zizixhobo ezininzi ezikhokelela ekusebenzeni okuzinze kakhulu kunye nokuchanekileyo.
• Zonke izixhobo zinedilesi yazo ekhethekileyo kwinkqubo yokuvula uluhlu olubanzi kakhulu lwamathuba olawulo oluguquguqukayo.

UDALI UFANISWA NJANI NE-1-10V?

I-DALI, njenge-1-10V, yenzelwe kunye neshishini lokukhanyisa.Amacandelo okulawula ukukhanya, njengabaqhubi be-LED kunye neenzwa, zifumaneka kuluhlu lwabavelisi abane-DALI kunye ne-1-10V interfaces.Nangona kunjalo, kulapho ukufana kuphela khona.

Umahluko ophambili phakathi kwe-DALI kunye ne-1-10V zezi:

• I-DALI iyalungiseka.Oku kuvula indlela yeempawu ezininzi ezixabisekileyo ezifana nokwahlulahlula, ukusetwa kwendawo kunye nolawulo oluguquguqukayo, olufana nokutshintsha ukuba zeziphi na izibonisi zoluvo kunye nokutshintsha kokulawula ukuba zeziphi izifakelo zokukhanya ekuphenduleni utshintsho kuyilo lweofisi.
• I-DALI yeyedijithali, hayi i-analogue.Oku kuthetha ukuba i-DALI inokubonelela ngolawulo lwenqanaba lokukhanya oluchanekileyo ngakumbi kunye nobumnyama obungaguqukiyo.
• I-DALI ngumgangatho, ngoko ke, umzekelo, igophe elimnyama lisemgangathweni othetha ukuba izixhobo ziyasebenzisana phakathi kwabavelisi.I-1-10V dimming curve ayizange ibekwe emgangathweni, ngoko ke ukusebenzisa iibrendi ezahlukeneyo zabaqhubi kwitshaneli yobumnyama efanayo kunokuvelisa iziphumo ezingangqinelaniyo kakhulu.
• I-1-10V inokulawula kuphela ukucima / ukuvala kunye nobumnyama obulula.I-DALI inokulawula ulawulo lombala, ukutshintshwa kombala, ukuvavanywa kokukhanya okungxamisekileyo kunye nengxelo, ukusetwa kwendawo entsonkothileyo kunye neminye imisebenzi emininzi yokukhanyisa.

ZONKEIMVELISO zeDALIIYAQHUBEKA NOMNYE?

Ngoguqulelo lwantlandlolo lwe-DALI, bekukho iingxaki ezithile zokuhambelana kuba iinkcukacha bezilinganiselwe kumda.Isakhelo sedatha ye-DALI nganye yayiyi-16-bits (i-8-bits yedilesi kunye ne-8-bits yomyalelo), ngoko ke inani lemiyalelo ekhoyo lalilinganiselwe kakhulu kwaye kwakungekho ukufunyanwa kokungqubana.Ngenxa yoko, abavelisi abaninzi bazama ukwandisa amandla abo ngokwenza ezongezo zabo, okukhokelela ekungahambelani okuthile.

Ngokufika kwe-DALI-2 le nto yoyisiwe.

• I-DALI-2 inebhongo ngakumbi kumda wayo kwaye iqulethe izinto ezininzi ebezingekho kuhlobo lokuqala.Isiphumo soku kukuba izongezo ezenziwe ngabavelisi ngabanye kwi-DALI azisasebenzi.Ukufumana inkcazo ethe kratya yoyilo lwe-DALI-2, nceda uye ku "Isebenza njani i-DALI", ngezantsi.
• I-logo ye-DALI-2 iphethwe yi-DiiA (i-Digital Illumination Interface Alliance) kwaye banamathele imiqathango engqongqo ekusebenziseni kwayo.Eyona nto iphambili kwezi kukuba akukho mveliso inokuthwala i-logo ye-DALI-2 ngaphandle kokuba idlule kwinkqubo yoqinisekiso oluzimeleyo ukujonga ukuthotyelwa ngokupheleleyo kwe-IEC62386.

I-DALI-2 ivumela ukusetyenziswa kwezinto zombini ze-DALI-2 kunye ne-DALI kufakelo olulodwa, ngokuxhomekeke kwezinye izithintelo.Enyanisweni, oku kuthetha ukuba abaqhubi be-DALI LED (njengomzekelo oyintloko) bangasetyenziselwa ukufakela i-DALI-2.

USEBENZA NJANI UDALI?

Ingundoqo ye-DALI yibhasi - iingcingo ezimbini ezithwala iimpawu zokulawula idijithali ukusuka kwizixhobo zokufaka (ezifana neenzwa), kumlawuli wesicelo.Umlawuli wesicelo usebenzisa imigaqo eye yacwangciswa ngayo ukuvelisa iimpawu eziphumayo kwizixhobo ezifana nabaqhubi be-LED.

• Iyunithi yonikezelo lwamandla ebhasi (PSU).Eli candelo lihlala lifuneka.Igcina i-voltage yebhasi kwinqanaba elifunekayo.
• Izixhobo zeLed.Zonke izixhobo zokukhanya kufakelo lwe-DALI zifuna umqhubi we-DALI.Umqhubi we-DALI unokwamkela imiyalelo ye-DALI ngokuthe ngqo kwibhasi ye-DALI kwaye uphendule ngokufanelekileyo.Abaqhubi banokuba yi-DALI okanye i-DALI-2 izixhobo, kodwa ukuba abayiyo i-DALI-2 abayi kuba nayo nayiphi na into entsha evezwe ngolu hlobo lwamva nje.
• Izixhobo zokufakwayo - izinzwa, iiswitshi njl njl. Ezi zinxibelelana nomlawuli wesicelo usebenzisa izakhelo zedatha ye-24-bit.Abanxibelelani ngokuthe ngqo nezixhobo zokulawula.
• Iziganeko.Rhoqo, isixhobo esinje ngenzwa siya kuba nenani lezixhobo ezahlukeneyo ngaphakathi kwalo.Ngokomzekelo, abenzi boluvo bahlala bebandakanya umtshini wokunyakaza (PIR), i-detector yezinga lokukhanya kunye ne-infra-red receiver.Ezi zibizwa ngokuba yimizekelo - isixhobo esinye sineemeko ezi-3.Nge-DALI-2 umzekelo ngamnye unokuba yinxalenye yeqela lolawulo elahlukileyo kwaye nganye inokujongwana nokulawula amaqela ahlukeneyo okukhanyisa.
• Izixhobo zokulawula - umlawuli wesicelo.Umlawuli wesicelo "yingqondo" yenkqubo.Ifumana imiyalezo ye-24-bit kwi-sensors (etc) kwaye ikhupha imiyalelo ye-16-bit kwisixhobo sokulawula.Umlawuli wesicelo uphinde ulawule i-traffic data kwibhasi ye-DALI, ukujonga ukungqubana kunye nokukhupha imiyalelo kwakhona njengoko kuyimfuneko.

Ii-FAQs

• Yintoni umqhubi weDALI?Umqhubi we-DALI ngumqhubi we-LED oya kwamkela igalelo le-DALI okanye i-DALI-2.Ukongeza kwitheminali yayo ephilayo & engathathi hlangothi iya kuba neetheminali ezibini ezongezelelweyo eziphawulwe DA, DA zokuncamathisela ibhasi yeDALI.Abaqhubi be-DALI banamhlanje baphatha i-logo ye-DALI-2, ebonisa ukuba baphantsi kwenkqubo yoqinisekiso olufunwa ngumgangatho wangoku we-IEC.
• Yintoni ulawulo lwe-DALI?Ulawulo lwe-DALI lubhekiselele kubuchwephesha obusetyenziselwa ukulawula ukukhanya.Obunye ubuchwephesha bukhona, ngokukodwa i-0-10V kunye ne-1-10V, kodwa i-DALI (kunye noguqulelo lwayo lwamva nje, i-DALI-2) ngumgangatho owamkelweyo kwihlabathi jikelele wolawulo lokukhanya kwezorhwebo.
• Usicwangcisa njani isixhobo se-DALI?Oku kuyahluka ukusuka kumenzi omnye ukuya komnye kwaye kuya kubandakanya amanyathelo amaninzi.Elinye lamanyathelo okuqala liya kuhlala libe kukwabela idilesi kwisixhobo ngasinye kufakelo.Ukucwangcisa kunokufezekiswa ngaphandle kwamacingo kunye nabavelisi abathile kodwa enye iya kufuna uqhagamshelo oluneentambo kwibhasi ye-DALI.
