Muaj pes tsawg watts ntawm incandescent teeb thiab lub zog- txuag lub teeb yog sib npaug rau 1 watt ntawm LED teeb?
Txij li thaum xyoo 1880, lub teeb incandescent tau muab rau tib neeg lub teeb pom kev zoo rau ze li 140 xyoo. Nws tuaj yeem hais tias tsis muaj nws, peb yuav siv ntau tshaj li ib nrab ntawm qhov chaw thiab lub sijhawm nyob rau hauv qhov tsaus ntuj thiab tsaus ntuj nyob rau hauv ib puas xyoo dhau los. Txawm li cas los xij, ntawm lub sijhawm no, lub zog- txuag lub teeb thiab LED qhov muag teeb nrog ntau lub zog txuag, lub neej ntev thiab kev ua haujlwm zoo dua qub tau dhau los ua neeg nyiam. Nyob rau hauv lub banner ntawm lub ntiaj teb no lub zog txuag thiab kev tiv thaiv ib puag ncig, lub teeb incandescent yog hais txog yuav raug tshem tawm los ntawm keeb kwm.
Ntau lub tebchaws thiab cheeb tsam tsim kho, suav nrog kuv lub tebchaws Taiwan, kuj tau tshaj tawm txoj kev npaj tshem tawm cov teeb pom kev zoo thaum ntxov li kaum xyoo dhau los. Piv txwv li, nyob rau hauv cov teb chaws Europe tsis ntev los no (uas tau ntev txwv tsis pub muag lub teeb incandescent), nws tau tshaj tawm hais tias nyob rau lub Cuaj Hli Ntuj 1, 2018, nws yuav tag nrho cov theem ntawm halogen teeb. Qhov tseeb, nyob rau hauv cov nthwv dej no, kev muag khoom thoob ntiaj teb tau nqis los ntawm 12 billion rau 2 billion hauv 10 xyoo dhau los.
Tam sim no, tib neeg hauv ntau lub teb chaws thiab cheeb tsam siv lub zog - txuag lub teeb thiab LED teeb. Tshem tawm cov teeb pom kev zoo, LED lub teeb thiab lub zog- txuag lub teeb muaj lub neej ua haujlwm ntev, ua kom pom kev zoo dua, thiab txuag hluav taws xob ntau dua thiab kev tiv thaiv ib puag ncig.
Txawm li cas los xij, ntau tus phooj ywg uas tau siv rau lub teeb ci tuaj yeem tseem nyob hauv lub tswv yim yav dhau los. Piv txwv li, nyob rau hauv lub era ntawm liab qab lub teeb qhov chaw teeb pom kev zoo, ib chav yuav xav tau 45W qhov muag teev, thiab cov chav siab yuav txawm xav tau 100W qhov muag teev. Qhov no wattage (lub zog) yog heev exaggerated nyob rau hauv lub era ntawm lub zog - txuag lub teeb thiab LEDs (lub brightness yuav nce exponentially, thiab nws yog unbearably kaj).
Qee zaum peb yuav pom lo lus "luminous efficiency", uas yog qhov peb hu ua luminous efficiency. Nws yog hais txog lub luminous flux (sawv cev los ntawm lub cim Φ los yog Φr) tso zis los ntawm lub teeb qhov chaw ib 1W ntawm hluav taws xob noj, thiab chav tsev yog lm / W.
Lumen (lm) yog chav tsev ntawm luminous flux, sawv cev rau qhov ci ntawm lub teeb. Qhov loj dua tus nqi lumen, qhov ci ntau dua. Feem ntau, cov ntim ntawm lub teeb thiab teeb ci tseem yuav kos tus nqi, uas tuaj yeem txiav txim ncaj qha uas yog ci dua.
Qhov ntawd yog hais tias, nyob rau hauv cov xwm txheej ntawm tib lub wattage thiab tib hom teeb, qhov siab dua qhov luminous efficiency, siab dua qhov ci thiab txuag hluav taws xob ntau dua.
Feem ntau, lub teeb incandescent muaj qhov ua tau zoo ntawm 12-24 lumens ib watt;
Lub teeb ua haujlwm ntawm lub zog- txuag lub teeb yog 30-40 lumens / watt;
Lub teeb pom kev zoo ntawm LED teeb tam sim no tuaj yeem yog 70-110 lumens / watt (qee qhov yuav siab li 200 lossis ntau dua, tab sis kuj tsawg).
Muaj pes tsawg watts ntawm incandescent teeb thiab lub zog- txuag lub teeb yog sib npaug rau 1 watt ntawm LED teeb? Lub teeb wattage conversion txoj kev
Luminous flux, illuminance
Cia peb muab piv txwv:
Thaum lub teeb pom kev zoo ntawm qee lub teeb ci yog 12LM / W, 40W incandescent teeb flux yog 480LM;
Thaum lub electro-kev hloov kho qhov muag ntawm ib lub teeb LED yog 70LM / W, 7W LED lub teeb flux yog 490LM;
Thaum lub electro-kev hloov kho qhov muag ntawm lub zog ntawm qee lub zog- txuag lub teeb yog 30LM / W, lub luminous flux ntawm 20W zog- txuag lub teeb yog 600LM.
Hauv lwm lo lus, qhov ci ci uas lub teeb ci tuaj yeem ua tiav nrog 40W ntawm kev siv lub zog, lub zog - txuag lub teeb xav tau ntau tshaj kaum watts, thiab LEDs tsuas xav tau 7W.
Yog li, raws li cov algorithm saum toj no, kev hloov pauv kev txawj ntse hauv lub rooj ua haujlwm raws li kev siv. Yog hais tias koj xav kom raug hloov lub wattage, koj kuj yuav tsum tau xa mus rau lub teeb efficiency ntawm lub teeb nws tus kheej. Thiab tus naj npawb ntawm watts ntawm LED qhov muag teev uas tsis tuaj yeem tua yuav tsum sib npaug ntawm cov watts ntawm lub teeb ci lossis lub zog- txuag lub teeb.
