Tom qab daim ntaub thaiv ntog, lub teeb hluav taws xob yuav pab peb daws teeb meem teeb pom kev zoo. Lub teeb hluav taws xob yog ib qho khoom siv hluav taws xob tsis tseem ceeb rau tsev neeg. Tam sim no cov teeb uas muag hauv khw feem ntau muab faib ua cov teeb ci LED thiab cov teeb incandescent. Yog li, nws puas yog tias cov teeb coj teeb muaj lub zog ntau dua li cov teeb pom kev zoo, thiab qhov sib txawv ntawm cov teeb ci incandescent thiab cov teeb coj teeb yog dab tsi?
Puas yog qhov tseeb tias cov teeb coj teeb muaj zog ntau dua li cov teeb ci?
Nws yog qhov tseeb tias cov teeb coj teeb muaj zog ntau dua li cov teeb pom kev zoo, vim tias cov teeb pom kev zoo ntawm cov teeb pom kev zoo siab dua li cov teeb ci incandescent. Nyob rau tib lub teeb ci, LED teeb siv lub zog tsawg dua li cov teeb pom kev zoo, thiab qhov ci ntawm LED teeb yog ntau dua li ntawm cov teeb ci incandescent. Hauv ib puag ncig ib puag ncig, 100-watt LED teeb tuaj yeem ua tiav qhov ci ntsa iab, thaum lub teeb incandescent xav tau 200 watts kom ua tiav qhov ci ntsa iab. Raws li peb txhua tus paub, qhov siab dua lub wattage, lub zog ntau dua yog siv, yog li nws yog qhov tseeb tias LED teeb muaj zog ntau dua li lub teeb incandescent.
Qhov sib txawv ntawm lub teeb incandescent thiab coj teeb
Thawj qhov sib txawv ntawm cov teeb ci incandescent thiab LED teeb yog tias lub teeb pom kev zoo sib txawv. Incandescent teeb tseem hu ua hluav taws xob qhov muag teev. Nws txoj hauv kev ua haujlwm yog tias cov cua sov tsim tawm thaum tam sim no dhau los ntawm cov filament, thiab cov kauv filament txuas ntxiv sib sau ua ke cov cua sov, ua rau qhov kub ntawm cov filament ntau dua 2000 degrees Celsius. Thaum cov filament nyob rau hauv lub xeev incandescent, nws zoo li liab-kub hlau. Nws tuaj yeem tawm teeb pom kev zoo li nws tuaj yeem ci.
Qhov kub ntawm cov filament ntau dua, lub teeb ci dua, yog li nws hu ua lub teeb incandescent. Thaum lub teeb incandescent emits lub teeb, ib tug loj npaum li cas ntawm hluav taws xob lub zog yog hloov mus rau hauv lub tshav kub lub zog, thiab tsuas yog ib tug me me npaum li cas yuav tsum tau hloov mus rau hauv lub teeb muaj txiaj ntsig.
LED teeb, tseem hu ua lub teeb-emitting diodes, yog cov khoom siv hluav taws xob 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 qhov tsis zoo electrode, thiab lwm kawg yog txuas nrog lub zoo electrode ntawm lub hwj chim mov, kom tag nrho cov nti yog encapsulated. los ntawm epoxy resin.
Ib tug semiconductor wafer muaj peb seem, ib feem yog P-hom semiconductor, nyob rau hauv uas lub dominate, lwm kawg yog N-hom semiconductor, uas yog feem ntau electrons, thiab nruab nrab feem ntau yog ib tug quantum zoo ntawm 1 mus rau 5 lub sij hawm. . Thaum cov tam sim no ua rau lub wafer los ntawm cov hlau, cov electrons thiab qhov yuav raug thawb mus rau hauv quantum zoo, qhov twg cov electrons thiab qhov recombine, thiab ces emit zog nyob rau hauv daim ntawv ntawm photons, uas yog lub hauv paus ntsiab lus ntawm LED teeb emission.
Qhov sib txawv thib ob yog qhov hluav taws xob hluav taws xob uas tsim los ntawm ob qhov sib txawv. Lub tshav kub ntawm lub teeb incandescent tuaj yeem hnov hauv lub sijhawm luv luv. Lub zog siab dua, qhov kub ntau dua. Lub zog hluav taws xob hloov pauv ib nrab rau lub teeb thiab ib nrab rau cua sov. Thaum tib neeg nyob ze heev, lawv tuaj yeem hnov cov cua kub tawm los ntawm lub teeb incandescent. .
LED hluav taws xob hluav taws xob hloov lub teeb lub zog, uas tsim hluav taws xob hluav taws xob tsawg heev, feem ntau ntawm lub peev xwm yog ncaj qha hloov mus rau hauv lub teeb lub zog, thiab lub zog ntawm cov teeb hluav taws xob tsis tshua muaj, ua ke nrog cov qauv hluav taws kub dissipation, piv nrog cov teeb incandescent, hluav taws xob hluav taws xob. LED txias lub teeb qhov chaw zoo dua.
Qhov thib peb qhov sib txawv yog tias lub teeb tawm los ntawm ob qhov sib txawv. Lub teeb emissions los ntawm incandescent teeb yog tag nrho-xim teeb, tab sis muaj pes tsawg leeg ntawm txhua lub teeb xim yog txiav txim los ntawm cov khoom luminescent thiab kub. Qhov sib piv tsis sib npaug ua rau cov xim cam ntawm lub teeb, yog li cov xim ntawm cov khoom tsis muaj tseeb txaus nyob rau hauv lub teeb incandescent.
LED yog lub teeb ntsuab. LED teeb yog DC tsav, tsis muaj stroboscopic, thiab tsis muaj infrared thiab ultraviolet Cheebtsam, tsis muaj hluav taws xob muaj kuab paug, siab xim rendering thiab muaj zog luminous directionality.
Tsis tas li ntawd xwb, qhov dimming kev ua tau zoo ntawm LED teeb yog qhov zoo, tsis muaj qhov pom kev yuam kev yuav tshwm sim thaum cov xim kub hloov, thiab lub teeb txias txias muaj tus nqi qis calorific thiab tuaj yeem kov yam xyuam xim. Nws yog lub teeb pom kev zoo uas tiv thaiv qhov muag thiab yog ib puag ncig zoo kom tau raws li tib neeg cov kev xav tau ntawm lub cev.
