Uma usembonini yezibani ze-landscape njengomkhiqizi, umklami wokukhanyisa, umsabalalisi, noma isicacisi somakhi, ngokuvamile uzodinga ukubhekisela kumafayela epulani le-Photometric le-IES ukuze uqonde ukuphuma kwangempela kokukhanya namandla e-lumen ezilungiselelweni ofisa ukuzifaka kudivayisi yakho. imiklamo.Kithina sonke embonini yezibani zangaphandle, lesi sihloko silapha ukuze sisisize siqonde kangcono indlela yokufunda nokuhlaziya imidwebo yokukhanyisa i-photometric.
Njengoba kushiwo yiWikipedia ngamagama alula njengereferensi yokuqonda i-optics;I-Photometry Isayensi yokulinganisa ukukhanya.Umbiko wokuhlaziywa kwe-photometric empeleni izigxivizo zeminwe zendlela isibani se-luminaire esiletha ukukhanya kwaso kulowo mklamo womkhiqizo oyingqayizivele.Ukuze ulinganise wonke ama-engeli okukhipha ukukhanya nokuthi ubukhulu bungakanani (okubuye kubizwe ngokuthi i-candela noma amandla ekhandlela), siqaphela ukuhlaziywa kwesibani esiletha ukukhanya, sisebenzisa into ebizwa ngokuthiI-Mirror Goniometerukuze usisize sibone lezi zici ezihlukahlukene zokukhishwa kokukhanya ngamandla nebanga elihlobene namaphethini akho.Le nsimbi ithatha amandla okukhanya (i-candela) futhi ililinganise ngama-engeli ahlukene.Ibanga ukusuka kusibani ukuya ku-Goniometer kufanele libe ngamafidi angu-25 noma kangcono ukuze uthole isilinganiso esifanele se-candela (ukuqina).Ukuze ukuhlaziywa kwesithombe se-IES kusebenze kahle, siqala ngokukala amakhandlela noma amandla ekhandlela ngamadigri angu-0 (uziro ungaphansi kwesibani noma phansi).Bese sihambisa i-goniometer ngamadigri angu-5 futhi siqhubeke siyinyakazisa kaningi, amanye amadigri angu-5 ngaphezulu isikhathi ngasinye eduze kwe-luminaire ukuze sifunde kahle ukuphuma kokukhanya.
IQONDA KANJANI INQUBO YOKULINGANA YOKUPHUMA KWE-PHOTOMETRIC LIGHT
Ngesinye isikhathi, sesihambe yonke indlela ezungeze ama-degree angu-360, sihambisa i-goniometer futhi siqale nge-engeli engama-degree angu-45 ukusuka lapho siqale khona futhi siphinda inqubo.Ngokuya ngokulungiswa kokukhanya kwezwe, singenza lokhu ngama-engeli ahlukahlukene ukuze sithwebule kahle okukhiphayo kwe-lumen kwangempela.Ishadi lekhandlela, noma ijika lamandla ekhandlela, lenziwa ngalolo lwazi futhi lisetshenziselwa ukudala lawa mafayela e-IES Photometric esiwasebenzisa embonini yokukhanyisa.Ku-engeli ngayinye ehlukene yokukhanya, sizobona ubukhulu obuhlukile be-luminaire evame ukuhluka phakathi kwabakhiqizi bokukhanyisa.Kube sekwakhiwa imodeli yokusabalalisa ukukhanya, ebizwa nangokuthi ijika lamandla ekhandlela, elibuye linikeze abaklami bokukhanyisa nabaklami bezakhiwo umfanekiso obonakalayo wokukhanya okusatshalaliswa yi-luminaire ngokusebenzisa i-optics, i-shrouds, kanye nokuma kwayo.
Uma sisuka kude nephuzu lokulinganisa elinguziro, kulapho ukukhanya kuphuma khona.Ithebula lokusabalalisa i-candela yijika le-candela kodwa elibekwe ngendlela yethebula.
Imidwebo yokukhanya kwe-photometric edalwe kusuka kulokhu okutholakele ikutshela ngokushesha ukuthi ukugeleza okuningi (ama-lumens, "ukugeleza kokukhanya") kuya phezulu kuya phansi noma emaceleni.
Ithebula lokusetshenziswa kwe-coefficient ku-photometry liyacabangelaiphesenti lokukhanya okuvela ezibani ezifinyelela endaweni yokusebenzaendaweni ethile.Isilinganiso somgodi wegumbi isilinganiso sezindonga nezindawo ezivundlile noma phansi endaweni yokusebenza.Izindonga zimunca ukukhanya okuningi.Lapho zimunca kakhulu, ukukhanya kuncipha ezindaweni lapho ukukhanya kukhanyiswa khona.Siphinde sibe namanani abukekayo kulawa mashadi acabangela amaphesenti okubonisa ukusuka phansi, izindonga, nosilingi.Uma izindonga ziwukhuni olumnyama olungakuvezi kahle ukukhanya, lokho kuzosho ukuthi ukukhanya okuncane kubonakaliswa endaweni yethu yomsebenzi.
Ukuqonda ukuthi konke lokhu okukhipha ukukhanya kusebenza kanjani kumkhiqizo ngamunye, kuvumela umklami wokukhanyisa ukuthi ahlele ngokunembile ubude lapho kufanele abeke khona isibani kanye nebanga phakathi kwezibani ukuze kukhanye kahle izikhala zangaphandle ukuze agcwalise leso sikhala ngokukhanya okusabalalisa ngokulinganayo.Ngalo lonke lolu lwazi, ukuhlelwa kwe-photometric nokuhlaziya kuzokuvumela (noma isofthiwe) ukuthi ukhethe kalula inani elifanele lezibani ezidingekayo ohlelweni lwephrojekthi yokukhanyisa enenzuzo kakhulu ngokufaka amandla afanele wamandla kanye namazinga okukhipha i-lumen ukuze udale ukumbozwa kokukhanyisa okuphelele. kusetshenziswa ukucaciswa okubonisa amadigri ama-engeli okukhanya ukukhanya ngakunye okuzowabonisa kumapulani abakhi besakhiwo.Lezi zindlela zokunquma imiklamo yokukhanyisa ye-landscape engcono kakhulu nezinhlelo zokufaka, zivumela ochwepheshe kanye nabaphathi bokuthenga amaphrojekthi amakhulu wokwakha ukuthi balawule kahle futhi baqonde ukuthi yiziphi izibani ezingcono kakhulu ukuzifaka endaweni enikeziwe kupulani lezakhiwo ezivela kubakhi, ngokusekelwe ekusabalaliseni ukukhanya. amajika kanye nedatha yokukhipha i-lumens.
