Umhlahlandlela Wendlela Yokukhetha Izibani Zezikhukhula ze-Basketball ze-LED
Ama-LED ayindlela enhle kakhulu yama-metal halides, ama-halogen, i-HPS, ama-mercury vapor namalambu e-fluorescent ngenxa yokusebenza kahle kwawo okuphakeme kwamandla nokuphila isikhathi eside. Manje ukukhanyisa kwe-LED kusetshenziswa kakhulu ezindaweni zokuhlala, ezohwebo noma ezichwepheshile, ikakhulukazi izibani eziphakeme ze-LED ezikhukhula zisetshenziselwa ukukhanyisa izinkundla zebhasikidi zasendlini noma zangaphandle. Namuhla, singathanda ukuhlola indlela yokukhetha amalambu esikhukhula senkundla ye-LED ukuze akhanyise inkundla yebhola lomnqakiswano.
1. Imfuneko yezinga eliphezulu lemicimbi engaboniswa kumabonakude
Idizayini yokukhanyisa namazinga ezinkantolo ze-basketball zokuhlala, zokungcebeleka, ezentengiselwano nezichwepheshile zangaphandle ze-basketball zingahluka. Ngokomhlahlandlela wokukhanyisa we-basketball (sicela ubone imfuneko yezinga lokukhanya elehlukile lemicimbi yasendlini nengaphandle njengoba izithombe ezilandelayo zibonisile), kuthatha cishe u-200 lux ngegceke langemuva nemicimbi yokuzijabulisa edingekayo. Njengoba inkundla ye-basketball evamile inendawo engamamitha angu-28 × 15 imitha (420 square metres), sidinga cishe 200 lux x 420 = 84,000 lumens.
Kodwa mangaki amandla esiwadingayo ukuze sikhanyisele inkundla ye-basketball okuhlanganisa nokuma ne-hoop? Ukukhanya kwethu okujwayelekile kwezibani zesikhukhula senkundla ye-LED ngu-170lm/w, ngakho sidinga okungenani ama-lumens angu-84,000/170 i-lumen ngayinye nge-watt=494 watt izibani ze-LED zezikhukhula (Vala izibani zezikhukhula ze-LED ezingu-500). Kodwa lena idatha elinganiselwe kuphela, wamukelekile ukuthintana nathi uma usidinga ukuthi sikunikeze umklamo wokukhanyisa ochwepheshile njengombiko we-DiaLux nanoma yiziphi izeluleko zamaphrojekthi akho okukhanyisa.
Amathiphu:
Ikilasi I: Lichaza imiqhudelwano ye-basketball esezingeni eliphezulu, yamazwe ngamazwe noma kazwelonke efana ne-NBA, NCAA Tournament kanye ne-FIBA World Cup. Leli zinga lokukhanya lidinga isistimu yokukhanyisa ukuze ihambisane nezidingo zokusakaza.
I-Class II: Ichaza ukuncintisana kwesifunda.Izindinganiso zokukhanyisa azisebenzi kangako ngoba ngokuvamile zihlanganisa imicimbi engeyona ekamabonakude.
Ikilasi III: Lichaza ukuzijabulisa okuvamile noma imisebenzi yokuqeqesha.
2. Izinga lokukhanyisa lemicimbi ye-basketball eboniswa ngumabonakude
Uma inkundla yakho ye-basketball noma inkundla yakhelwe imiqhudelwano yokusakaza efana ne-NBA ne-FIBA World Cups, izinga lokukhanyisa kufanele lifinyelele ku-2000 lux. Ngaphezu kwalokho, isilinganiso phakathi kwe-lux encane nephezulu enkundleni ye-basketball akufanele yeqe u-0.5. Izinga lokushisa lombala kufanele libe sebangeni lokukhanya okumhlophe okubandayo njengokusuka ku-5000K kuya ku-6500K futhi futhi i-CRI iphezulu njengo-90.
3. Ukukhanyisa okungaxhomeki kahle kwabadlali be-basketball nababukeli
Esinye isici esibalulekile sesistimu yokukhanyisa yasenkantolo ye-basketball umsebenzi wokulwa nokuxhopha. Ukukhanya okunamandla kwenza umdlali azizwe engakhululekile futhi ecwayiza. Le nkinga igqame kakhulu ezinkundleni ze-basketball ezingaphakathi ngenxa yephansi elikhanyayo. Ngezinye izikhathi kudingeka sisebenzise ukukhanya okungaqondile, okusho ukukhomba ukukhanya kosilingi phezulu bese sisebenzisa ukukhanya okukhanyayo ukukhanyisa inkundla. Ngakho-ke, sidinga amandla engeziwe ezibani ze-LED ukunxephezela ukukhanya okumuncwe uphahla oluphezulu.
4. Izibani ze-LED ezingacwayizi enkundleni yebasketball
Ngaphansi kwamakhamera anesivinini esiphezulu, ikhwalithi yamalambu ezikhukhula ajwayelekile ayilungile. Kodwa-ke, ama-floodlights ethu e-LED afakwe izinga lokundiza eliphansi kakhulu elingaphansi kuka-0.3%, elingatholwa yikhamera ngesikhathi somncintiswano.
