Xim kub paub txog LED teeb qhov chaw
Thaum peb yuav LED teeb, peb feem ntau ntsib cov uas hais tias qhov no yog lub teeb txias dawb, uas yog nruab nrab lub teeb dawb, sov dawb lub teeb, thiab lwm yam. ntawm LED teeb nyem. Cov yam ntxwv xim ntawm cov teeb pom kev dav dav thiab cov teeb ci tseem muaj xim kub specifications.
Yuav ua li cas paub qhov txawv ntawm qhov kub thiab txias ntawm cov teeb pom kev sib txawv no, thiab peb yuav tsum xaiv qhov uas haum rau peb thaum yuav khoom li cas? Cia peb saib cov kev paub txog cov xim kub ntawm LED teeb qhov chaw rau txhua tus.
qhov kaj
Lub teeb nyob rau hauv qhov xwm txheej tsis yog ib txwm zoo ib yam, thiab pom cov xim ntawm ib yam khoom nyob ntawm lub teeb ci ci rau nws. Kev hais lus dav dav, txhua yam uas tuaj yeem cuam tshuam cov hluav taws xob hluav taws xob hauv qhov pom lub teeb wavelength ntau tuaj yeem hu ua lub teeb ci; nqaim hais lus, nws hais txog lub teeb pom kev zoo, thiab lub teeb lub zog hluav taws xob uas tuaj yeem muab kev faib tawm ntau dua ntawm lub teeb lub zog nyob rau hauv tag nrho cov teeb pom kev zoo wavelength ntau yam yog lub teeb ci.
xim kub
Xim kub yog tus yam ntxwv ntawm chromaticity zoo ntawm lub teeb qhov chaw, lub xim nyiam thiab xim saturation ntawm lub teeb qhov chaw. Thaum cov xim ntawm lub teeb tawm los ntawm lub teeb ci yog tib yam li cov xim ntawm lub teeb hluav taws xob los ntawm lub cev dub ntawm qhov kub thiab txias, qhov kub ntawm lub cev dub yog hu ua xim kub ntawm lub teeb ci.
Yog hais tias ib yam khoom kub hnyiab, thawj cov nplaim taws yog xim liab, ces thaum kub nce nws puv txiv kab ntxwv-daj, ces dawb, thiab thaum kawg, xiav tshwm. Tus Scottish mathematician thiab physicist Lord Kelvin thawj zaug nrhiav tau kev sib raug zoo ntawm tshav kub thiab xim nyob rau hauv 1848, thiab tawm hauv lub ntiaj teb no nrog ib tug zoo kawg nkaus lub tswv yim ntawm "tsis muaj xoom" (-273.16 degrees Celsius). Txij thaum ntawd los, Kelvin ntsuas kub tau tsim, uas yog xim kub uas peb tab tom tham txog niaj hnub no.
Hais txog cov xim kub thiab xim zoo ntawm lub teeb ci, nws tuaj yeem txiav txim siab tias qhov kub ntawm cov xim ntau dua, qhov txias dua lub teeb, thiab qhov kub ntawm cov xim, qhov sov dua lub teeb.
Cov xim kub ntawm lub teeb ci txawv, thiab xim lub teeb kuj txawv. Cov xim kub hauv qab 3300K muaj qhov chaw ruaj khov thiab sov so; xim kub yog nyob nruab nrab ntawm 3000-5000K, uas yog nruab nrab xim kub, uas muaj ib tug refreshing; cov xim kub siab tshaj 5000K muaj qhov txias txias.
Kelvin nplai qhia qhov kub thiab txias hauv chav K (cov ntawv luv rau kelvin), nrog cov lej qis dua sawv cev ntau "liab" thiab cov lej siab dua uas sawv cev ntau "xiav". Liab thiab xiav tsis yog xim ntawm lub teeb nws tus kheej, tab sis tsuas yog qhia tias muaj ntau xim liab lossis xiav nyob rau hauv spectrum.
Correlated xim kub ntawm txawv lub teeb qhov chaw ib puag ncig:
Xim kub tsuas yog qhia cov spectral muaj pes tsawg leeg ntawm lub teeb qhov chaw, tsis yog lub luminous siv. Cov xim kub kub qhia tau tias muaj cov khoom siv luv luv, uas yog xiav-ntsuab; qhov kub tsis tshua muaj xim qhia tau hais tias muaj cov khoom sib txuas ntev ntev, uas yog xim liab-daj. Txawm hais tias xim kub ntawm lub teeb ci tsis yog lub tswv yim nrog lub ci ci, xim kub ncaj qha cuam tshuam rau qhov ci thiab qhov sib txawv.
Vim tias qhov sib txheeb xim kub yog qhov tseeb ze rau lub teeb xim ntawm lub teeb ci nrog cov hluav taws xob lub cev dub, qhov kev ntsuam xyuas tus nqi ntawm lub teeb xim kev ua tau zoo ntawm lub teeb ci tsis yog qhov sib piv xim, yog li ob lub teeb pom kev zoo tib yam xim kub. tus nqi tseem yuav tshwm sim nyob rau hauv lub teeb xim tsos. Muaj qhov sib txawv me ntsis. Xim kub ib leeg tsis tuaj yeem qhia tias lub teeb ci tuaj yeem ua rau cov khoom xim zoo li cas, lossis zoo npaum li cas cov khoom xim rov ua dua nyob rau hauv qhov teeb pom kev zoo.
Ntau yam xim kub kub ntawm LED teeb:
(1) Lub teeb txias txias, xim kub siab tshaj 6500K, lub teeb ci yog nyob ze rau lub teeb ntuj, nrog lub teeb ci, haum rau feem ntau, ci ntsa iab, tshwj xeeb tshaj yog tsim rau cov teeb pom kev loj, xws li tshawb nrhiav thiab cawm, nrhiav, kev tshawb nrhiav, thiab lwm yam.
(2) Lub teeb pom kev zoo, nrog cov xim kub ntawm 5500K thiab 6500K, lub teeb pom kev zoo ntawm lub teeb dawb tsis zoo li lub teeb txias dawb, tab sis nws tseem ci heev, haum rau ntau lub sijhawm sab nraum zoov, xws li hmo ntuj nce toj, taug txuj kev nyuaj. , kev ua si sab nraum zoov, thiab lwm yam;
(3) Lub teeb nruab nrab dawb, xim kub nruab nrab ntawm 3500K ~ 5500K, lub teeb nruab nrab ntawm lub teeb dawb yog me me, haum rau feem ntau lub teeb nyem, xws li ntawm lub luag haujlwm, nuv ntses, sab nraum zoov, thiab lwm yam.
(4) Lub teeb sov dawb 2100K ~ 3500K, lub teeb sov dawb yog mos thiab tuaj yeem ua rau tib neeg sov thiab xis nyob. Haum rau kev siv me me, xws li sab hauv tsev, tsev pheebsuab camping, picnic, khiav hmo ntuj, thiab lwm yam.
