I-LED Color Temperature
Njengoba ukukhanya okuningi okukhishwa umthombo wokukhanya kuhlangene kubizwa ngokuthi ukukhanya okumhlophe, izinga lokushisa lethebula lombala noma izinga lokushisa elihlobene lombala womthombo wokukhanya lisetshenziselwa ukubhekisela ezingeni umbala okhanyayo omhlophe ngokuqhathaniswa ukuze ulinganise ukukhanya. ukusebenza kombala komthombo wokukhanya. Ngokombono kaMax Planck, umzimba omnyama ojwayelekile onokumuncwa okuphelele kanye ne-radioactivity uyashiswa, futhi izinga lokushisa liyakhula kancane kancane, futhi ukukhanya kushintsha ngokufanele; i-Locus yomzimba omnyama esikalini sombala we-CIE ikhombisa inqubo yomzimba omnyama obomvu-owolintshi-ophuzi-ophuzi-omhlophe-omhlophe-oluhlaza okwesibhakabhaka-omhlophe. Izinga lokushisa lapho umzimba omnyama ufudunyezwa ngokufanayo noma eduze nomthombo wokukhanya lichazwa njengezinga lokushisa elihlobene lombala womthombo wokukhanya, elibizwa ngokuthi izinga lokushisa eliphelele K (Kelvin noma u-Kelvin) (K=°C+273.15) . Ngakho-ke, lapho umzimba omnyama ushiselwa kumbala obomvu, izinga lokushisa lingaba ngu-527 ° C, okungukuthi, 800 K, namanye amazinga okushisa athinta ukushintsha kombala.
Lapho umbala okhanyayo uba luhlaza okwesibhakabhaka, izinga lokushisa lombala liyanda; umbala obomvu yiwona ophansi izinga lokushisa lombala. Umbala wokukhanya emini nawo uyashintsha ngokuhamba kwesikhathi: imizuzu engu-40 ngemva kokuphuma kwelanga, umbala okhanyayo uphuzi, izinga lokushisa lombala lingu-3,000K; ilanga lasemini limhlophe, likhuphukela ku-4,800-5,800K; Emini ngezinsuku eziguqubele, cishe ku-6,500K; ngaphambi kokushona kwelanga, umbala ubabomvu futhi izinga lokushisa lombala lehla libe ngu-2,200K. Izinga lokushisa elihlobene lombala weminye imithombo yokukhanya, ngenxa yokuthi izinga lokushisa lombala ohlobene empeleni liyimisebe yomzimba omnyama esondela kumbala womthombo wokukhanya, inani lokuhlola lokusebenza kombala womthombo wokukhanya alikona ukugqama kombala okunembile, ngakho imithombo yokukhanya emibili inokufana okufanayo. inani lokushisa lombala, Kungase kube khona umehluko othile ekubukekeni kombala okhanyayo. Izinga lokushisa lombala lilodwa alikwazi ukuqonda ikhono lokunikeza umbala lomthombo wokukhanya entweni, noma ukuthi umbala wento ukhiqizwa kanjani kabusha ngaphansi komthombo wokukhanya.
Izinga lokushisa lombala elihlobene lezindawo ezihlukene zomthombo wokukhanya
Usuku oluguqubele 6500-7500k
Ukukhanya kwelanga kwasehlobo emini 5500K
Isibani se-Metal halide 4000-4600K
Ukukhanya kwelanga ntambama 4000K
Ukukhanya kwekamu lombala opholile 4000-5000K
I-high pressure mercury isibani 3450-3750K
Ukukhanya kwekamu lombala ofudumele 2500-3000K
Isibani seHalogen 3000K
Ukukhanya kwekhandlela 2000K
Izinga lokushisa lombala lomthombo wokukhanya lihlukile futhi umbala okhanyayo uhlukile. Ukushisa kombala kungaphansi kwe-3300K, kukhona umoya ozinzile, umuzwa wokufudumala; izinga lokushisa lombala lingu-3000--5000K lokushisa lombala omaphakathi, futhi kunomuzwa oqabulayo; izinga lokushisa lombala linomuzwa obandayo ongaphezu kuka-5000K. Imibala ehlukene yokukhanya yemithombo yokukhanya ehlukene yakha indawo engcono kakhulu.
Izinga lokushisa lombala umbono weso lomuntu wezikhanyisi noma izibonisi ezimhlophe. Lona umuzwa we-physics. Izici eziyinkimbinkimbi neziyinkimbinkimbi ze-physiology kanye ne-psychology nazo zihlukile kumuntu nomuntu. Izinga lokushisa lombala lingashintshwa ngendlela yomuntu ku-TV (i-illuminator) noma ukuthwebula (i-reflector). Isibonelo, sisebenzisa isibani sokushisa esingu-3200K (3200K) ukuze sithathe izithombe, kodwa sengeza isihlungi esibomvu kulensi. Ukuhlunga ngokukhanya okuncane okubomvu kwenza isithombe sibukeke siphansi ngokushisa kombala; isizathu esifanayo, singakwazi futhi ukunciphisa okubomvu okuncane ku-TV (kodwa ukunciphisa kakhulu kuzophinde kuthinte ukusebenza okuvamile okubomvu) ukwenza isithombe sibukeke sifudumele kancane.
Okuncanyelwayo kwezinga lokushisa lombala kunqunywa abantu. Lokhu kuhlobene nemvelo yansuku zonke esiyibonayo. Isibonelo, kubantu abaseduze nenkabazwe, izinga lokushisa elimaphakathi elibonwa nsuku zonke ngu-11000K (8000K (ukuhlwa) ~ 17000K (emini)). Ngakho-ke ngincamela izinga lokushisa lombala ophezulu (okubonakala kungokoqobo). Ngokuphambene, abantu abane-latitudes ephakeme (isilinganiso sokushisa sombala esingaba ngu-6000K) bakhetha izinga lokushisa eliphansi lombala (5600K noma 6500K), okusho ukuthi uma usebenzisa okuphakeme Izinga lokushisa le-TV lombala ukukhombisa indawo ye-Arctic, ibonakala iluhlaza ngokwengxenye; ngokuphambene nalokho, uma usebenzisa i-TV yokushisa kombala ophansi ukuze ubone isitayela se-subtropical, uzozizwa ubomvu kancane.
Ichazwa kanjani izinga lokushisa lombala we-TV noma isikrini sokubonisa? Ngenxa yokuthi izinga lokushisa elimaphakathi lombala endaweni yase-China licishe libe ngu-8000K kuya ku-9500K unyaka wonke, ukukhiqizwa kohlelo lwesiteshi se-TV kusekelwe ekushiseni kombala kombukeli okungu-9300K. Kodwa-ke, ngenxa yokuthi izinga lokushisa lombala eYurophu naseMelika lihlukile kwelethu, izinga lokushisa eliphakathi konyaka wonke lilinganiselwa ku-6000K. Ngakho-ke, uma sibheka lawo mafilimu angaphandle, sizothola ukuthi i-5600K~6500K ifaneleka kakhulu ukubukwa. Yiqiniso, lo mehluko usenza sibe nomuzwa wokuthi lapho sibona isihenqo se-computer noma se-TV eYurophu naseMelika, sinomuzwa wokuthi izinga lokushisa lombala libomvu futhi lifudumele, kanti amanye awafaneleki.
