Ubushushu bombala
Xa i-blackbody esemgangathweni ifudunyezwa (njengocingo lwe-tungsten kwisibane se-incandescent), umbala we-blackbody uqala ukutshintsha ngokuthe ngcembe kumnyama obomvu - obomvu okhanyayo - o-orenji - otyheli - omhlophe - oluhlaza okwesibhakabhaka njengoko ubushushu busanda.Xa umbala wokukhanya okhutshwa ngumthombo wokukhanya ufana nowomntu omnyama oqhelekileyo kwiqondo lobushushu elithile, sibiza ubushushu obupheleleyo bomntu omnyama ngelo xesha njengobushushu bombala bomthombo wokukhanya, obumelwe bubushushu obupheleleyo. : K.
(Imvakalelo eqhelekileyo yobushushu bombala) Uluhlu loku-1
| ubushushu bombala | umbala okhanyayo | isiphumo somoya |
| ＞5000K | pholile (bluish white) | ingqele kunye nokuziva ulahliwe |
| 3300K-5000K | phakathi (kufutshane nokukhanya kwendalo) | akukho mpembelelo ibonakalayo yengqondo |
| ＜3300K | shushu (ezimhlophe neentyatyambo eziorenji) | imvakalelo eshushu neswiti |
(Ukubona ubushushu bombala) Itheyibhile II

Ulungelelaniso lombala
Ulungelelwaniso kwingoma ye-blackbody kuthiwa ubushushu bombala, kwaye kukho ulungelelwaniso oluqinisekileyo;ulungelelwaniso olungaphandle kwetrajectory yomntu omnyama (kufutshane netrajectory yomntu omnyama) zibizwa ngokuba yiehambelanayoUbushushu bombala, obukwabizwa ngokuba bubushushu bombala.Umzekelo, ngenxa yobushushu bombala we6250k, ulungelelwaniso lombala x=0.3176 y=0.3275.Iqondo lobushushu, ukusuka ezantsi ukuya phezulu, onke amanqaku obushushu bombala enza umgca (igophe), obizwa ngokuba yi "blackbody color temperature trajectory".
Nangona kunjalo, ubushushu bombala ekudla ngokubhekiswa kuwo ngoku eneneni "ubushushu bombala ohambelanayo" (CCT);"Iqondo lokushisa lombala" likwasetyenziselwa inqaku (ukulungelelanisa) elingekho kwingoma kodwa lingekho kude, kwaye ixabiso layo lobushushu bombala lixabiso lenqaku elisondeleyo kumzila.Ngale ndlela, ngenxa yobushushu bombala ofanayo, kukho amanqaku amaninzi
ngaphandle komzila, kunye nemigca yokudibanisa yala manqaku ibizwa ngokuba yi "isotherms";Oko kukuthi, zonke izinxibelelanisi kulo mgca zinobushushu obufanayo bombala.Nika umfanekiso.Amanani akumzobo abonisa "isotherm", ijika yi "blackbody trajectory", kwaye iellipse luluhlu olulungelelanisiweyo6500k isibaneichazwe ngurhulumente.
Le theyibhile ingezantsi ngeenkcukacha
Ulungelelwaniso lweChromaticity lulungelelwaniso lwemibala.Ngoku ulungelelwaniso lombala olusetyenziswa ngokuqhelekileyo, i-axi ethe tyaba ngu-x, kwaye i-axi ethe nkqo ngu-y.Nge-chromaticity coordinate coordinates, inqaku linokumiselwa kwi-chromaticity coordinate.Le ngongoma imele ngokuchanekileyo umbala okhanyayo.Oko kukuthi, ulungelelwaniso lwechromaticity lumele ngokuchanekileyo umbala.Ngenxa yokuba ulungelelwaniso lwechromaticity lunamanani amabini kwaye alunangqiqo, abantu bayathanda ukusebenzisa ubushushu bombala ukubonisa ngokucacileyo umbala oqaqambileyo womthombo wokukhanyisa.Enyanisweni, ubushushu bombala bubalwa ngolungelelwaniso lwechromaticity, kwaye ubushushu bombala alinakufumaneka ngaphandle kolungelelwaniso lwechromaticity.Ukuba inombala omnyama kakhulu, onjengoluhlaza, oluhlaza okwesibhakabhaka, njl njl. ungabala "i-wavelength engundoqo" kunye "nobunyulu bombala" ngolungelelwaniso lwechromaticity ukumela umbala ngokubonakalayo.Kwizibane zokugcina amandla, urhulumente uchaze ezi mfuno zilandelayo zokulungelelanisa i-chromaticity, kwaye ixabiso lokutenxa lingaphantsi kwe-5SDM.

Imizobo eqhotyoshelweyo kunye nomgangatho weenkwenkwezi zamandla
Phakathi kwemibala emithathu ephambili, ebomvu kuphela enobushushu bombala obumalunga ne-900K, ngelixa eminye imibala ayinambono wobushushu bombala.Umz: intsimbi ayizujika ibeluhlaza okanye iblue nokuba ifudunyezwa njani na.Ubushushu bombala busetyenziselwa ukumela umbala wokukhanya kokukhanya (kufuphi nomhlophe).Ubushushu bombala ophantsi, omhlophe ngotyheli, obizwa ngokuba yithoni efudumeleyo;Ubushushu bombala ophezulu, omhlophe nobhlowu, obizwa ngokuba yithoni ebandayo.Ukukhanya okuluhlaza akunakubonakaliswa ngobushushu bombala;Isibane esiluhlaza kwakhona asinalo ubushushu bombala.
Siyabona ukuba umahluko wolungelelwaniso lwechromaticity kwiziphelo zombini ze-isotherm uyabonakala, oko kukuthi, ubushushu bombala obunxibeleleneyo buyafana (okt kwi-isotherm), kodwa umahluko wombala wokukhanya kwawo unokubonwa ngeliso lomntu. .Xa kukho umahluko othile kwiqondo lobushushu elinxibeleleneyo lombala, umahluko wombala unokwenzeka ngakumbi.Ngokubanzi, abavelisi be-LED bahlela ubushushu bombala wabo ohambelana ne-LED ngokweemfuno zemigangatho ehambelanayo.Akukho ngxaki ekusetyenzisweni kweendawo zokukhanyisa ngokubanzi, kodwa kwiimeko zokufaka izicelo ezineemfuno ezingqongqo zokwahlukana kombala, iimveliso ze-LED ezinolungelelwaniso lwemibala emihle kufuneka zikhethelwe ukuveliswa.
