Muaj pes tsawg lumens yuav tsum muaj dej nyab sab nraum zoov?

Excerpt/Introduction

Thaum kuv xub pib ua hauj lwm rausab nraum zoov dej nyab teeb, Kuv kuj xav tias qhov no yog ib lo lus nug yooj yim heev. Tsuas yog muab cov neeg ntau dua lumens, ci ntsa iab zoo dua, txoj cai?
Tab sis tom qab xyoo ntawm kev sim teeb pom kev hauv thaj chaw tiag tiag, kev tsav tsheb, cov chaw tsim khoom, thiab qee zaum cov neeg siv khoom npau taws, kuv tuaj yeem hais qhov no kom meej: lumens ib leeg tsis txiav txim siab seb lub teeb dej nyab yog qhov zoo lossis phem.

Cov neeg feem ntau yws hais tias, "Lub teeb no tsaus dhau lawm," los yog qhov opposite, "Nws yog txoj kev kaj heev, kuv txawm saib tsis tau." Feem ntau, qhov teeb meem tsis yog cov khoom zoo, tab sis tsis ncaj ncees lawm lumen xaiv rau qhov chaw tsis ncaj ncees lawm. Cia peb tham txog nws nyob rau hauv ib txwm txoj kev, los ntawm cov khoom engineer pom, tsis yog kev lag luam tham.

Lumens tiag tiag txhais li cas hauv cov khoom tiag

Ntawm daim ntawv, lumens txhais tau tias tag nrho cov teeb pom kev zoo. Nyob rau hauv lub Hoobkas kuaj, nws yog ntsuas nyob rau hauv ib tug lab sphere, huv si heev, zoo meej heev. Tab sis kev siv sab nraum zoov yog ntxhov.

Los ntawm kev xeem engineering:

Cua, plua plav, phab ntsa xim, mounting qhov siab tag nrho txo ​​qhov ci tiag tiag

A "3000-lumen"dej nyab teebTej zaum yuav xa tsuas yog 70-80% muaj txiaj ntsig teeb rau hauv av

Yog li ntawd, engineers yeej tsis saib lumens ib leeg. Peb saib cov kev ua haujlwm kho qhov muag, lub kaum sab xis, thiab kev tswj kom sov.

Raws li US DOE cov ntaub ntawv, LED efficiency ranges ntawm 80 mus rau 160 lm / W, nyob ntawm tus nti zoo thiab tus tsav tsheb tsim. Qhov kev sib txawv ntawd loj heev hauv lub neej tiag tiag.

Yog li, Muaj pes tsawg Lumens yuav tsum muaj dej nyab sab nraum zoov?

Nov yog cov lus teb ncaj ncees: nws nyob ntawm qhov chaw koj nruab nws thiab nws siab npaum li cas. Tab sis raws li cov phiaj xwm tiag tiag, muaj ntau yam kev nyab xeeb.

Vaj & Pem Hauv Ntej Vaj Teeb pom kev zoo

800-1,200 lumens

Los ntawm cov neeg siv kev tawm tswv yim thiab kev sim kev teeb tsa, qhov ntau yam no zoo siab. Nroj tsuag cuam tshuam lub teeb tsis sib npaug, yog li qhov ci ntsa iab ntau dhau yuav zoo dua.

Cov ntaub ntawv (2022-2023):
Txog 70% ntawm cov neeg siv nyiam nyob ib ncig ntawm 1000 lumens rau thaj chaw vaj. Tshaj 1500 lumens, kev tsis txaus siab pib tshwm sim.

Txoj Kev thiab Kev Taug Kev

1,500-2,200 lumens

Qhov no yog tej zaum qhov feem ntau yuam kev cheeb tsam. Cov neeg yuav 4000 lumens thiab khuv xim nws.

Engineer logic:

Mounting qhov siab:~ 2.5-3 m

Lub hom phiaj brightness:30-40 lux ntawm av

Lub teeb 1800-lumen dej nyab nrog lub kaum sab xis zoo feem ntau ua tau raws li qhov no yooj yim.

Backyard & Patio Areas

1,800-2,500 lumens

Thaj chaw no suav nrog tib neeg, tsis yog tsheb. Qhov muag tseem ceeb.

Thaum kuaj cov khoom, ib zaug peb mus saum 3000 lumens, cov neeg siv piav qhia lub teeb xws li:

"Tau ntse heev"

"Zoo li lub Hoobkas"

"Tsis relaxing"

Yog li engineers feem ntau cap nws qis dua.

Kev ruaj ntseg teeb pom kev zoo (chaw nres tsheb, Sab yard)

2,500-4,000 lumens

Ntawm no qhov ci ntsa iab yog qhov tau txais ntau dua, tab sis kev tswj hwm beam yog qhov tseem ceeb.

Piv txwv tiag:

3000 lumens / 120℃beam → lub teeb nyob txhua qhov chaw, tab sis tsis muaj zog sib piv

2500 lumens / 90℃beam → zoo dua duab ntxoov ntxoo, zoo visibility

Kev ruaj ntseg teeb pom kev zoo yog hais txog kev pom kev txav mus los, tsis yog teeb pom kev rau tag nrho lub ntiaj teb.

Cov kev tshawb fawb txog kev tiv thaiv kev ua phem qhia tau tias lub teeb pom kev zoo tuaj yeem txo qhov tawg - nyob rau hauv kev pheej hmoo los ntawm 30–40%.

Thaj chaw loj lossis kev lag luam siv

4,000 lumens thiab siab dua

Tam sim no peb nkag mus rau engineering taub hau cheeb tsam. Kev tswj kom sov ua haujlwm hnyav.

Hauv cov qauv pheej yig, lumen poob tom qab 6-12 lub hlis tuaj yeem ncav cuag 20-30% vim tias muaj cua sov dhau. Cov neeg siv xav tias lub teeb "tau qub," tab sis nws yog thermal tsis ua haujlwm.

Vim li cas Lumens Siab dua feem ntau poob hauv lub neej tiag

Los ntawm cov neeg siv khoom xa rov qab cov ntaub ntawv:

Ci ntsa iab heev ua rau glare

Glare ua rau tsis xis nyob

Kev tsis xis nyob ua rau muaj kev tshuaj xyuas tsis zoo

Tsis tas li ntawd, lub teeb muaj kuab paug yog tiag tiag. Lub Koom Haum Ntiaj Teb Tsaus Ntuj -Sky Association tshaj tawm lub nroog suburban ntuj ci nce 10-20% nrog cov teeb pom kev nyab xeeb uas tsis tswj tau.

Raws li engineers, peb kawm tau ib yam ceev:

Yog hais tias tus neeg siv xav tias annoyed, cov khoom twb ua tsis tau tejyam.

LED vs Halogen: Ntsuas, Tsis Tshaj Tawm

Cov lej xeem tiag:

150W Halogen Dej nyab lub teeb

Rated: ~ 2800 lumens

Tom qab kub poob: ~ 2200 lumens

30W LED Dej nyab lub teeb

Rated: ~ 3000 lumen

Cov zis ruaj khov tom qab 1 xyoos: ~ 2600-2700 lumens

LED yeej tsis yog vim kev lag luam, tab sis vim nws nyob ruaj khov.

Xim kub tseem ceeb dua li tib neeg xav

Lumens hais li cas ci. Xim kub hais tias nws xav li cas.

3000K - sov, tus phooj ywg, tab sis qhov sib piv qis dua

4000K - sib npaug, qis tshaj tus nqi tsis txaus siab

5000K + - ntse, zoo rau kev ruaj ntseg, nkees rau kev siv txhua hnub

Los ntawm kev tshawb fawb engineers, 4000K yog qhov kev xaiv zoo tshaj plaws rau feem ntau cov teeb pom kev nyab xeeb sab nraum zoov.

Feem ntau yuam kev kuv pom dua thiab dua

Yuav tus lej lumen siab tshaj plaws

Tsis quav ntsej beam angle

Mounting siab dhau lawm, ces liam qhov ci

Xaiv cov tsav tsheb pheej yig uas flicker tom qab

Ib rooj plaub rov qab tseem funny:
Cov neeg yuav khoom 5000 lumens, hais tias "dub dhau lawm." Qhov teeb meem tiag tiag? 150℃beam kaum sab xis, lub teeb nkim txhua qhov chaw.

Yooj yim zog nqi piv txwv

3000-lumen LED dej nyab teeb (30W), siv 6 teev ib hnub

Kev siv lub hli: ~ 5.4 kWh

Tus nqi: kwv yees li $0.8–$1 / hli

Brightness tsis sib npaug daim nqi hluav taws xob siab ntxiv lawm.

FAQs (Cov lus nug tiag tiag los ntawm cov neeg siv khoom)

Puas yog 2000 lumens txaus sab nraum zoov?
Yog, rau feem ntau siv hauv tsev, nws zoo tag nrho.

Puas yog 4000 lumens ntau dhau lawm?
Rau vaj, yog. Rau kev nyab xeeb lossis thaj chaw dav, tsis muaj.

Vim li cas kuv lub teeb pom kev dim tom qab lub hli?
Thaum tshav kub kub thiab tsav tsheb laus, tsis yog lumen ntsuam xyuas.

Cov lus kawg (Tsis yog lag luam, Tsuas yog Kev Paub)

Yog li, yuav tsum muaj pes tsawg lumens sab nraum dej nyab lub teebua?
Los ntawm cov khoom engineers sab, qhov chaw qab zib rau cov tsev feem ntau yog 1,500-3,000 lumens, nrog optics zoo thiab txhim khu kev qha.

Ntau lumens yuav tsis kho qhov tsim tsis zoo.
Kho lub teeb, tso cai, yeej ib txwm yeej.
