Lokushisa umbala

Umqondo, elihunyushwe isihloko sihloko, is kabanzi isicelo emkhakheni wesayensi nomsebenzi esisebenzayo, njengoba isayensi yokuma kwezinto ezisemkhathini, ukukhiqizwa izinhlobo ezahlukene izibani nokuhlunga. Imvelo ezingokomzimba imihlola agcwele lokushisa umbala, ukuthi kudala njalo umgomo ngoba bezibona umbala by ehlweni lomuntu. Ngo incazelo eziyinkimbinkimbi, kukhombisa isakhiwo Spectral we emisebeni sasikhipha emthonjeni othile. Njengoba kombala iso buvezwa izici subjective zomzimba womuntu, kwemizwa isimo uhlelo, okubonakalayo uhlelo nemingcele, izakhiwo Spectral ka objectification ukusetshenziswa ekhethekile umbala ukusatshalaliswa isikali kuye umthombo lokushisa.

Ngokwesibonelo, izinga lokushisa umbala kuqala okuqonda sibonwa esweni womuntu ngoba izinto ashisayo noma imigwamanda kuyinto 800 K.

Le ngxenye ephawula ukushuba umthombo emisebeni ngaphakathi kobubanzi optical. namagugu awo kubalwa Kelvin.

Ngokuvumelana nezindinganiso Ucwaningo esungulwe, ukukhanyisa ilangabi ikhandlela kuyabonakala lapho lokushisa yayo 1500-2000 K, futhi ukuvutha elula esikhipha isibani amandla 40 Watts iba Ukwethwasa at 2000 K. Ngokuvamile, izinga lokushisa umbala ama-globe kagesi kunqunywa umthamo wabo futhi zokhahlamba kusuka 2000 K kuya ku-3000 K, izindinganiso ezivamile ezivela abathengi (40 - 200 W). Izibani ezivamile asetshenziswe ukuqopha nobuchwepheshe kinovosproizvodyaschey babe lokushisa 3200-3250 K. Sun lapho bengena umkhathizwe kubonakala, uma izinga lokushisa umbala 3000 K, emini - 5000 K, kodwa amafu, ukuze kuzobonakala, kumele " efudumele "isivele kuze kufinyelele 5500 K.

Phakathi izenzakalo zezulu lokushisa eliphakeme has licwathile nge lokushisa nobusika 15000 K, futhi lo mkhuba ezifanayo eziyizinhlupheko zindawo enyakatho, lapho izinga lokushisa umbala bengase bazikhandlele abakuzuzile 20,000 K.

Icala ezivamile lapho abantu bangaqaphela, lesi sibalo, yebo, ukusetshenziswa izinhlobo ezihlukahlukene zezindwangu ezingaba ukukhanyisa zalapho, izibani ifakwe. Lapha, ngokwesibonelo, manje kusetshenziswa kakhulu emakhaya kanye nezinye izindawo izibani Fluorescent abe okuningi ephakeme amagugu lokushisa. Ngokusho umbala lokushisa Fluorescent isibani, kuye ngokuthi nezinye izici zalo, kungaba kusuka 2700 kuya 7700 K ngesikhathi ukufinyela zabo esiphezulu.

Sepharamitha umbala lokushisa elisetshenziswa kakhulu izithombe namabhayisikobho. Ngokwesibonelo, iyiphi ifilimu umbala senziwa amagugu fixed ngokuphelele izinga lokushisa umbala. Lokhu ibangelwa kukhwalithi ephezulu umbala. Uma uphelelwa slide noma badutshulwe angemahle noma adubula okusezingeni eliphezulu ubude ebalulekile, udinga ifilimu olusebenzisa balance sheet umbala lokushisa - mayelana 5600 K ngoba emini 3200 K ngokudubula ebusuku.

Ngo amakhamera lanamuhla elisebenzisa ubuchwepheshe ziyasebenza umphumela okulinganisa, kodwa lokhu ibangelwa ukulungiswa okuzenzakalelayo fotoustroystva noma inketho esethiwe.

Abasembonini yokunyathelisa ukunikeza imikhiqizo high quality, nobuchwepheshe isetshenziswa ulungise lokushisa umbala kuzo zonke izigaba inqubo ukukhiqizwa. Kahle lapha kuyinto ukubaluleka 6500 K. Ngezinye value kunikezwa umthombo wokukhanya edonsa ultraviolet e oyiyo isakhi akuyona ziqondakala ehlweni lomuntu. Kodwa ezinye izinto kuba ezingeni umbala lokushisa ukukhanya up, okuyinto unikeza ephrintiwe imikhiqizo ukhalaza futhi okwakhe ezinjalo. Ngaphezu kwalokho, besebenzisa ubuchwepheshe mphumela kufinyelelwa lapho "mhlophe" lephepha elimhlophe esimweni ngaphezu value amaphesenti ayikhulu.
