Xaiv teeb: yuav ua li cas muaj ntau yam lumens ib watt incandescent teeb 100?

Lumen (luminous flux) yog ib chav tsev ntawm kev ntsuas ntawm SI - International System of Chav. Qhov no teeb tus nqi, denoted "lumens" los yog lm.

hloov lub teeb

Cov suav tau ntev pom tau tias cov incandescent teeb - tsis yog lub zoo tshaj plaws kev xaiv rau teeb pom kev zoo, tshwj xeeb tshaj yog thaum nws tawm los rau loj cheeb tsam. Tus tsov ntxhuav feem ntawm lub zog yog tsis nyob rau hauv lub teeb pom kev zoo thiab rau cua sov rau cov filament, uas ua rau cov qhov muag teev zoo li ib tug me me rhaub.

Cov lus nug txog cov zog yog tshwj xeeb yog ib qho tseem ceeb tam sim no, nyob rau hauv lub sij hawm ntawm siab noj ntawm cov kev pab thiab, tseem ceeb tshaj rau tau txais kev pab, siab dua tus nqi rau hlauv taws xob. Yog li ntawd, thaum koj yuav tau yuav tsum tau them nyiaj mloog tsis tau lub hwj chim, ntsuas nyob rau hauv watts, thiab ntau npaum li cas lub teeb yuav sib me ntsis. Thiab cia li no parameter yog hloov nyob rau hauv lumens.

Yuav ua li cas muaj ntau yam lumens ib watt incandescent teeb 100

Tej yaj yog feem ntau siv nyob rau hauv pej xeem chaw. Lawv muab ib tug zoo zoo nkauj teeb pom kev zoo thiab xis mus rau lub qhov muag xim. Txij li thaum Lumens qhia ntau npaum li cas lub teeb yog tawm txim liab los ntawm lub qhov chaw, ntau dua qhov lub nqi, lub zog lub teeb. Txawm li cas los, cov nuj nqis tej zaum yuav txawv lug, tshwj xeeb tshaj yog thaum nws tawm los rau ntau hom kev teeb. Nws yog ib qhov nyuaj rau xam ntau npaum li cas lumens nyob rau hauv ib tug incandescent teeb 100 watts. Piv txwv li, ib tug 20-watt teeb muab lub teeb flux ntawm 250 lumens, thiab yog hais tias lub hwj chim yog ob npaug, lub khiav yuav mus txog 400 lm. Tab sis lub 60-watt noob nyob rau hauv tus nqi ntawm txog 700 lumens, 900 lumens sib npaug zos rau lub hwj chim ntawm 75 watts. Cov flow peev xwm ntawm 1200 lumens ntawm lub teeb yog tiav yog tias lub hwj chim ntawm filament teeb yog 100 watts.

zog optimization

Tam sim no los yog yav tom ntej, cov neeg no thaum pib los mus xav txog yuav ua li cas tseg rau hluav taws xob, vim hais tias kev kawm tsis sawv tseem. Thawj tuaj lub zog-txuag qhov muag teev, uas, raws li lub chaw tsim tshuaj paus, kom tsis txhob muaj zog noj nyob rau hauv ob los sis peb lub sij hawm. Thiab tam sim no muaj ntau heev tshaj dua roj-npaum qhov muag - LED. Lawv tsuas yog tsis zoo - tus nqi yog heev siab heev, li ntawd, lub ntsiab qhov teeb meem yog hais tias tus tshiab teeb yog muaj thiab tsawg heev zog noj, thiab qhov kev ci ntawm lub incandescent teeb.

deception

LED teeb tsis haus ob peb lub sij hawm tsawg lub hwj chim, tab sis cov lus qhia rau cov chaw tsim tshuaj paus, feem ntau confuses lub buyer. Piv txwv li, hais tias ib lub teeb zoo xws li cov 70-watt qhov muag teev nrog 500 lumens, tab sis nws muaj peev xwm tsis muaj tseeb. Nyob rau hauv thiaj li tsis mus yuav yuam kev nrog rau cov kev xaiv, peb yuav tsum nco ntsoov yuav ua li cas muaj ntau yam lumens nyob rau hauv ib tug incandescent teeb 100 watts.

Tom qab lub purchase ntawm cov khoom no ib tug neeg yog chim, vim hais tias cov teeb yog tsis txaus thiab koj yuav tsum hloov mus rau ib tug ntau haib ntaus ntawv, uas yog txuam nrog ib co nqi ntxiv, tshwj xeeb tshaj yog yog hais tias tus qhov muag raug muas rau lub tag nrho chandelier. Txawm li cas los, thaum ib tug kev hloov no yog tsim nyog them sai sai tsis tsuas mus rau xws li ib tug loj raws li lumens. Luminous flux / fais fab - qhov no piv nyob rau hauv lub International System of Chav (SI), uas yog hu ua tus luminous efficiency. Cias muab, lub parameter qhia tau hais tias yuav ua li cas brightness outputs 1 Watt ntawm ib lub teeb qhov chaw. Ntsuas nyob rau hauv lumens ib watt.

Yuav ua li cas los xaiv?

Noj rau hauv tus account tag nrho cov tsis, koj yuav tsum xav txog tsis tsuas yuav ua li cas muaj ntau yam lumens ib watt incandescent teeb 100, tab sis lub teeb tso zis, uas yog sib npaug zos rau 100 watts ntawm 13,8 lm / W. Piv txwv li: tib parameter nyob rau hauv lub LED qij yuav ua tau los ntawm 10 mus rau 300 lm / W (!).

Lwm undeniable zoo dua yog qhov transparency ntawm lub filament teeb iav thiab lub kaum sab xis ntawm beam kis ntawm 360 degrees. Yog li ntawd, thaum hloov mus rau lwm cov hom (piv txwv li, lub LED teeb lub ob zaug tsawg) tej zaum yuav muaj cai degradation ntawm illumination. Nyob rau hauv tas li ntawd, nws yog ib qho incandescent teeb yog zoo tagnrho rau cov dimmers uas yuav tswj tsis tau tsuas yog cov brightness, tab sis kuj lub hwj chim noj.

ntawv

Raws li ib tug txoj cai, cov lus qhia txog yuav ua li cas muaj ntau yam lumens ib watt incandescent teeb 100, yuav nrhiav tau nyob rau hauv lub ntim. Nyob rau hauv tas li ntawd, muaj cov qhia tseem ceeb tsis xws li xim kub thiab xim rendering index (CRI), txoj cai xaiv uas, koj yuav tau txais lub feem ntau xis rau lub qhov muag teeb ntxoov ntxoo.

Xim kub customary incandescent teeb yog 2800 K (ntsuas nyob rau hauv degrees Kelvin). Qhov no muaj nuj nqis thiab yuav tsum tau ua nyob rau hauv kev xaiv cov xim lub teeb, ntawm chav kawm, yog ib tug lub tsev. Rau workspaces (chaw ua hauj lwm, tsev kho mob, khw muag tshuaj, cov khw) haum nruab nrab tones nrog ib tug xim kub ntawm 4000 mus 5000 K, thiab cov duab thiab exhibition halls yog pom zoo kom npog lub teeb fluorescent (5000 K thiab saum toj no).

raug

Yog hais tias yog vim li cas nws yog ib qho tseem ceeb uas lub teeb pom kev zoo thaum hloov lub teeb nyob qis qis raws nraim nyob rau tib theem, yuav ua tau pre-ntsuas lub teeb tso zis los ntawm ib tug tshwj xeeb ntaus ntawv - lub teeb 'meter'. Suite - ib qho kev ntsuas ntawm tus piv ntawm lumens thiab Cheeb Tsam (1 lux yog sib npaug zos rau ib lumen ib square meter). Feem ntau qhov no siv rau ntau yam hauv tsev, qhov twg nws yog tsim nyog los saib xyuas kev ruaj ntseg ntawm lub teeb pom kev zoo lub xeev cov kev cai.

Tricks rau Zog Efficiency

Ib tug ntawm cov nthuav tswv yim los ntawm cov tub txawg yog yuav siv tau yaj ntawm txawv zog. Piv txwv li, ib tug ntau haib illumination yog yuav tsum tau nyob rau hauv cov ua hauj lwm hauv cheeb tsam ntawm lub chav tsev, thiab nyob rau hauv tej qhov chaw nws yog ua tau los mus tswj ib tug me me muaj pes tsawg tus ntawm suites. Ob txhais ntsis - Cais switching ntawm lub teeb. Qhov no ua kom yuam kev yuav tsis tau tsuas yog haus tsawg zog, tab sis kuj yuav muab cov qhab nyob rau hauv lub studio tsev los yog loj chav.
