Xa ukwishishini lokukhanyisa imbonakalo yomhlaba njengomvelisi, umyili wokukhanyisa, umsasazi, okanye isicacisi soyilo, kuya kufuneka uhlale ubhekisa kwiifayile zesicwangciso sefotometric ye-IES ukuqonda isiphumo sokwenyani sokukhanya kunye namandla e-lumen kwizilungiso onqwenela ukuzifaka kwisixhobo sakho. uyilo.Kuthi sonke kwishishini lokukhanyisa ngaphandle, eli nqaku lilapha ukusinceda ukuba siqonde ngcono indlela yokufunda nokuhlalutya imizobo yokukhanyisa i-photometric.
Njengoko kuchaziwe yi-Wikipedia kweyona migaqo ilula njengereferensi yokuqonda i-optics;I-Photometry Ngaba inzululwazi yomlinganiselo wokukhanya.Ingxelo yohlalutyo lwe-photometric ngenene luphawu lweminwe lwendlela isibane sokukhanya kwe-luminaire sinikezela ngokukhanya kwaso kuyilo olulodwa lwemveliso.Ukuze kulinganiswe zonke ii-angles zokukhanya kunye nokuba yintoni na ubukhulu (ekwabizwa ngokuba yi-candela okanye amandla ekhandlela), siqaphela uhlalutyo lwe-luminaire ehambisa ukukhanya, sisebenzisa into ebizwa ngokuba yi-candela.Isipili Goniometerukusinceda ukuba sichonge le miba yahlukeneyo yokukhanya okuphumayo ngokomelela kunye nomgama ngokunxulumene neepateni zakho.Esi sixhobo sithatha ubunzulu bokukhanya (i-candela) kwaye siyilinganisela kwii-engile ezahlukeneyo.Umgama ukusuka kwisibane ukuya kwi-Goniometer kufuneka ube yi-25 iinyawo okanye ungcono ukufumana umlinganiselo ochanekileyo we-candela (ubunzima).Ukuze uhlalutyo lwe-photometric lwe-IES lusebenze ngokufanelekileyo, siqala ngokulinganisa amakhandlela okanye amandla ekhandlela kwii-degrees ze-0 (i-zero ingaphantsi kwesibane okanye ezantsi).Emva koko sihambisa i-goniometer 5 degrees kwaye siqhubeke siyihambisa ngokuphindaphindiweyo, enye i-5 degrees ngaphezulu kwexesha ngalinye yonke indlela ejikeleze i-luminaire ukuze ufunde ngokufanelekileyo ukuphuma kokukhanya.
IYIQONDA NJANI INKQUBO YOMLINGANISO WE-PHOTOMETRIC LIGHT
Kanye, xa sihamba yonke indlela malunga ne-360 degrees, sihambisa i-goniometer kwaye siqale kwi-angle ye-45-degree ukusuka apho siqale khona kwaye siphinda inkqubo.Ngokuxhomekeke kwisibane sokukhanya komhlaba, sinokukwenza oku kwii-engile ezahlukeneyo ukuze sibambe ngokufanelekileyo iziphumo zokwenyani zelumen.Itshathi yekhandlela, okanye igophe lamandla ekhandlela, yenziwe kolo lwazi kwaye isetyenziselwa ukwenza ezi fayile ze-IES Photometric esizisebenzisayo kushishino lokukhanyisa.Kwi-angle nganye eyahlukileyo yokukhanya, siya kubona ubukhulu obuhlukeneyo be-luminaire ehlala iyingqayizivele phakathi kwabavelisi bokukhanya.Imodeli yokusasazwa kokukhanya iye yenziwa, ikwabizwa ngokuba ligophe lamandla ekhandlela, elibonelela abaqulunqi bokukhanyisa kunye nabayili bezakhiwo kunye nomboniso obonakalayo wokukhanya osasazwa yi-luminaire ngokusebenzisa i-optics yayo, i-shrouds, kunye neemilo.
Okukhona sisuka kude ukusuka kwindawo engu-zero yomlinganiselo, kokukhona kuphuma ukukhanya okukhulu.Itheyibhile yokuhanjiswa kwecandela yigophe lecandela kodwa ibekwe kwimo yetheyibhuli.
Imizobo yokukhanya yefotometric eyenziwe kwezi zinto zifunyanisiweyo ikuxelela ngoko nangoko ukuba uninzi lwe-flux (i-lumens, "ukuhamba kokukhanya") iye phezulu ezantsi okanye emacaleni.
Itheyibhile yokusetyenziswa kwe-coefficient kwiphotometry iqwalaselaipesenti yokukhanya kwezibane ezifikelela kwindawo yokusebenzakwindawo ethile.Umlinganiselo wegumbi lomgodi ngumlinganiselo weendonga ukuya kwiindawo ezithe tye okanye imigangatho ukuya kwindawo yokusebenza.Iindonga zifunxa kakhulu ukukhanya.Okukhona zifunxa ngakumbi, kokukhona kuncipha ukukhanya kwiindawo apho ukukhanya kukhanya khona.Sikwanazo nexabiso lokubonisa kwezi tshathi eziqwalasela iipesenti zokubonisa ukusuka kumgangatho, iindonga, kunye neesilingi.Ukuba iindonga zezomthi omnyama ongabonisi ukukhanya kakuhle, oko kuya kuthetha ukuba ukukhanya okuncinci kubonakaliswa kumphezulu wethu womsebenzi.
Ukuqonda indlela yonke le mveliso yokukhanya esebenza ngayo kwimveliso nganye, ivumela umyili wokukhanyisa ukuba acwangcise ngokuchanekileyo ubude bokubeka isibane kunye nomgama phakathi kwezibane ukuze zikhanyise ngokufanelekileyo izithuba zangaphandle ukuze zizalise eso sithuba ngokukhanya okwabiwe ngokulinganayo.Ngalo lonke olu lwazi, ukucwangciswa kwefotometric kunye nohlalutyo kuya kukuvumela (okanye isoftware) ukuba ukhethe ngokulula isixa esifanelekileyo sezibane ezifunekayo kwisicwangciso seprojekthi yoyilo lokukhanyisa oluluncedo ngokufaka umbane kumandla afanelekileyo ombane kunye namanqanaba emveliso yelumen ukwenza oko kugutyungelwa kokukhanya kokukhanya. usebenzisa iinkcukacha ezibonisa amaqondo eengile zokukhanya ukukhanya ngakunye kuya kubonisa kwiiplani zezakhiwo zepropati.Ezi ndlela zokumisela ezona zikhanyiso zokukhanya komhlaba kunye nezicwangciso zofakelo, zivumela iingcali kunye nabaphathi bokuthenga iprojekthi yokwakha enkulu ukuba balawule ngokufanelekileyo kwaye baqonde ukuba zeziphi izibane ezifanelekileyo ukuzifaka kwindawo enikiweyo kwiplani yepropathi evela kubakhi bezakhiwo, ngokusekwe kunikezelo lokukhanya. iigophe kunye nedatha yemveliso yelumens.
