LED teeb VS incandescent teeb

Vim li cas ntau thiab ntau tus neeg nyiam siv lub teeb LED es tsis txhob siv lub teeb ci?

Nov yog qee qhov kev sib piv, tej zaum nws tuaj yeem pab peb nrhiav cov lus teb.

Thawj qhov sib txawv ntawm cov teeb ci incandescent thiab LED teeb yog lub teeb pom kev zoo.Lub teeb incandescent tseem hu ua lub teeb hluav taws xob.Nws txoj hauv kev ua haujlwm yog tias cov cua sov tsim tawm thaum tam sim no dhau los ntawm cov filament.Cov kauv filament txuas ntxiv khaws cov cua sov, ua rau qhov kub ntawm cov filament ntau tshaj 2000 degrees Celsius.Thaum cov filament nyob rau hauv lub xeev incandescent, nws zoo li liab hlau.Nws muaj peev xwm emit lub teeb ib yam li nws ci.

Qhov kub ntawm cov filament ntau dua, lub teeb ci dua, yog li nws hu ua lub teeb incandescent.Thaum lub teeb incandescent emit lub teeb, ib tug loj npaum li cas ntawm hluav taws xob lub zog yuav hloov mus rau hauv lub tshav kub zog, thiab tsuas yog ib tug me me feem yuav hloov dua siab tshiab rau hauv lub teeb muaj txiaj ntsig.

LED teeb tseem hu ua lub teeb-emitting diodes, uas yog cov khoom siv hauv lub xeev semiconductor uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb.Lub plawv ntawm LED yog semiconductor nti, ib kawg ntawm nti yog txuas mus rau lub bracket, ib kawg yog tus ncej tsis zoo, thiab lwm kawg yog txuas nrog lub zoo ncej ntawm lub hwj chim mov, kom tag nrho cov nti yog encapsulated. los ntawm epoxy resin.

Lub semiconductor wafer yog tsim los ntawm peb qhov chaw, ib feem yog P-hom semiconductor, nyob rau hauv uas qhov dominate, lwm kawg yog N-hom semiconductor, ntawm no yog cov electrons, thiab nruab nrab feem ntau yog quantum zoo nrog 1 txog 5. lub voj voog.Thaum cov tam sim no ua rau lub nti los ntawm cov hlau, cov electrons thiab qhov yuav raug thawb mus rau hauv lub qhov dej quantum.Nyob rau hauv quantum qhov dej, cov electrons thiab qhov recombine thiab ces emit zog nyob rau hauv daim ntawv ntawm photons.Qhov no yog lub hauv paus ntsiab lus ntawm LED teeb emission.

Qhov sib txawv thib ob yog nyob rau hauv cov hluav taws xob hluav taws xob uas tsim los ntawm ob.Lub tshav kub ntawm lub teeb incandescent tuaj yeem hnov ​​​​hauv lub sijhawm luv luv.Lub zog loj dua, qhov kub ntau dua.Ib feem ntawm kev hloov hluav taws xob hluav taws xob yog lub teeb thiab ib feem ntawm cov cua sov.Tib neeg tuaj yeem hnov ​​​​cov cua kub tawm los ntawm lub teeb incandescent thaum lawv nyob ze heev..

LED hluav taws xob lub zog hloov mus rau hauv lub teeb lub zog, thiab cov hluav taws xob hluav taws xob tsim tawm tsawg heev.Feem ntau ntawm lub peev xwm yog ncaj qha hloov mus rau hauv lub teeb lub zog.Ntxiv mus, lub zog ntawm cov teeb pom kev dav dav yog tsawg.Ua ke nrog cov qauv ntawm cov cua kub dissipation, cov hluav taws xob hluav taws xob ntawm LED txias lub teeb qhov chaw zoo dua li cov teeb ci incandescent.

Qhov thib peb qhov sib txawv yog tias lub teeb tawm los ntawm ob qhov sib txawv.Lub teeb emissions los ntawm lub teeb incandescent yog tag nrho-xim lub teeb, tab sis qhov sib piv ntawm ntau yam xim teeb yog txiav txim los ntawm cov khoom luminescent thiab kub.Qhov sib piv tsis sib haum ua rau cov xim cam ntawm lub teeb, yog li cov xim ntawm cov khoom nyob rau hauv lub teeb incandescent tsis muaj tiag tiag.

LED yog lub teeb ntsuab.LED teeb yog tsav los ntawm DC, tsis muaj stroboscopic, tsis muaj infrared thiab ultraviolet Cheebtsam, tsis muaj hluav taws xob muaj kuab paug, kuj muaj xim rendering thiab muaj zog luminous directivity.

Tsis tas li ntawd, lub teeb ci LED muaj qhov ua tau zoo dimming, tsis muaj qhov pom kev yuam kev tshwm sim thaum cov xim kub hloov, thiab lub teeb txias txias muaj qhov tsim hluav taws xob tsawg thiab tuaj yeem kov tau zoo.Nws tuaj yeem muab qhov chaw teeb pom kev zoo thiab qhov zoo Nws yog lub teeb pom kev zoo uas tiv thaiv qhov muag thiab yog ib puag ncig tus phooj ywg kom tau raws li tib neeg lub cev xav tau kev noj qab haus huv.
