Izinga lokushisa lombala
Lapho i-blackbody ejwayelekile ishiselwa (njengocingo lwe-tungsten esibanini se-incandescent), umbala womzimba omnyama uqala ukushintsha kancane kancane eduze kobomvu obumnyama - obomvu ngokukhanyayo - osawolintshi - ophuzi - omhlophe - oluhlaza okwesibhakabhaka njengoba izinga lokushisa likhuphuka. Lapho umbala wokukhanya okhishwa umthombo wokukhanya ufana nalowo we-blackbody ejwayelekile ezingeni lokushisa elithile, sikubiza izinga lokushisa eliphelele le-blackbody ngaleso sikhathi njengezinga lokushisa lombala lomthombo wokukhanya, elimelelwa izinga lokushisa eliphelele. : K.

Izixhumanisi zombala
Izixhumanisi kuthrekhi ye-blackbody zibizwa ngokuthi izinga lokushisa lombala, futhi kukhona izixhumanisi eziqondile; izixhumanisi ezingaphandle kwe-blackbody trajectory (eduze ne-blackbody trajectory) zibizwa ngokuthikuhlobeneizinga lokushisa lombala, elibizwa nangokuthi izinga lokushisa lombala. Ngokwesibonelo, ngoba lokushisa umbala we6250k, umbala wokuhlanganisa x=0.3176 y=0.3275. Izinga lokushisa, ukusuka phansi ukuya phezulu, wonke amaphuzu okushisa ombala akha umugqa (ijika), obizwa ngokuthi "i-trajectory yokushisa kombala omnyama".
Kodwa-ke, izinga lokushisa lombala okuvame ukukhulunywa ngalo manje empeleni "izinga lokushisa lombala elihlobene" (CCT); "Izinga lokushisa lombala" lisetshenziselwa iphuzu (ukuxhumanisa) elingekho kuthrekhi kodwa elingekho kude, futhi inani layo lokushisa lombala liyinani lephoyinti eliseduze kakhulu nethrekhi. Ngale ndlela, ngokushisa okufanayo kombala, kunamaphuzu amaningi
ngaphandle kwethrekhi, futhi imigqa yokuxhuma yala maphuzu ibizwa ngokuthi "isotherms"; Okusho ukuthi, zonke izixhumanisi kulo mugqa zinezinga lokushisa lombala elifanayo. Nikeza isithombe. Izibalo ezisesithombeni zibonisa i-"isotherm", ijika "i-blackbody trajectory", futhi i-ellipse ububanzi bokuxhumanisa6500k isibanieshiwo nguhulumeni.
Ithebula elingezansi ukuze uthole imininingwane
I-Chromaticity coordinate izixhumanisi zemibala. Manje izixhumanisi zombala ezivame ukusetshenziswa, i-eksisi evundlile ithi x, futhi i-eksisi eqondile ithi y. Ngezixhumanisi zokuxhumanisa i-chromaticity, iphoyinti linganqunywa kusixhumanisi se-chromaticity. Leli phuzu limelela ngokunembile umbala okhanyayo. Okusho ukuthi, i-chromaticity coordinate imele ngokunembile umbala. Ngenxa yokuthi i-chromaticity coordinate inezinombolo ezimbili futhi ayinembile, abantu bathanda ukusebenzisa izinga lokushisa lombala ukuze baveze cishe umbala okhanyayo womthombo wokukhanyisa. Eqinisweni, izinga lokushisa lombala libalwa ngesixhumanisi se-chromaticity, futhi izinga lokushisa lombala alikwazi ukutholwa ngaphandle kokuxhumanisa kwe-chromaticity. Uma inombala omnyama kakhulu, njengoluhlaza okotshani, oluhlaza okwesibhakabhaka, njll. ungakwazi ukubala "i-wavelength eyinhloko" kanye "nokuhlanzeka kombala" ngokusebenzisa i-chromaticity coordinate ukuze ubonise umbala. Kumalambu okonga amandla, umbuso ubeke izidingo ezilandelayo zokuxhumanisa i-chromaticity, futhi inani lokuchezuka lingaphansi kuka-5SDCM.

Imidwebo enamathiselwe kanye nezinga lenkanyezi yamandla
Phakathi kwemibala emithathu eyinhloko, okubomvu kuphela okunokushisa kombala okungaba ngu-900K, kuyilapho eminye imibala ingenawo umqondo wokushisa kombala. Isib: insimbi ngeke ibe luhlaza noma ibe luhlaza okwesibhakabhaka kungakhathaliseki ukuthi ishiswa kanjani. Izinga lokushisa lombala lisetshenziselwa ukumela umbala wokukhanya kokukhanyisa (eduze nomhlophe). Ukushisa kombala ophansi, okumhlophe okuphuzi, okubizwa ngokuthi ithoni efudumele; Izinga lokushisa lombala ophakeme, omhlophe noluhlaza okwesibhakabhaka, okubizwa ngokuthi ithoni ebandayo. Ukukhanya okuluhlaza akukwazi ukuvezwa izinga lokushisa lombala; Ukukhanya okuluhlaza okwesibhakabhaka nakho akunalo izinga lokushisa lombala.
Siyabona ukuthi umehluko we-chromaticity izixhumanisi kuzo zombili iziphetho ze-isotherm usobala, okungukuthi, izinga lokushisa lombala elihlobene liyafana (okungukuthi ku-isotherm), kodwa umehluko wombala wokukhanya kwawo ungase futhi ubonwe iso lomuntu. . Uma kunomehluko othile kuzinga lokushisa lombala elihlobene, umehluko wombala ungenzeka kakhulu. Ngokuvamile, abakhiqizi be-LED bahlukanisa izinga lokushisa lombala wabo ohlobene we-LED ngokwezidingo zamazinga ahambisanayo. Ayikho inkinga ekusetshenzisweni kwezindawo zokukhanyisa okuvamile, kodwa ezikhathini zokufaka izicelo ezinezidingo eziqinile zomehluko wombala, imikhiqizo ye-LED enezixhumanisi zemibala emihle kufanele ikhethelwe ukukhiqizwa.
Okulandelayo yireferensi enikezwe i-Energy Star:
