Cov txheej txheem rau xaiv BR30 LED qhov muag teev

Koj tuaj yeem txiav txim siab hloov cov teeb pom kev tsis tu ncua hauv koj qhov chaw nyob thiab ntsib qee yam qauv. Dab tsi yog cov txheej txheem rau kev yuav ib qho LED retrofit hloov?
Tshaj tawm saum toj no yog tsib - kauj ruam tswv yim kom tau txais aBR30 LED teeb.

Characterizing ibBR30 teeb

BR30 teeb yog kwv yees li 5 ntiv tes ntev thiab me me hauv qab 4 ntiv tes inch. Lawv nyob rau hauv cov pab pawg ntawm cov teeb pom kev zoo, uas yog feem ntau "dav dej nyab" beam kaum sab xis.
Thaum pib, cia peb txheeb xyuas cov lus sau. BR txhais tau hais tias "Bulged Reflector," xa mus rau sab nrauv sab nrauv ntsib thaum tsiv tawm ntawm lub qhov (socket), los yog cov teeb pom kev zoo ntawm lub teeb lub cev. Qhov no sib piv nrog PAR lossis MR- zoo li lub teeb.
Lub pob ntawm incandescent BR30 teeb yog tsim los pab kom muaj kev nyab xeeb dav dav ntawm 120 degrees lossis ntau dua. Lub reflector lub flaring tsim tso cai rau lub teeb emitted los ntawm lub filament mus disperse tshaj ib tug dav lub kaum sab xis.
Tom qab ntawd, peb tshuaj xyuas tus lej "30." Hauv cov khoom siv teeb pom kev zoo feem ntau, tus lej qhia txog lub teeb txoj kab uas hla hauv yim feem ntawm ib nti. Lub "30" qhia txog lub teeb kab ntawm 30/8 ntiv tes, sib npaug rau 3.75 ntiv tes.
LED teeb tau khaws cia BR30 daim ntawv tsim qauv. BR30 LED teeb, thaum piv rau qhov loj me rau PAR30 LED teeb, yog qhov txawv ntawm lawv lub kaum sab xis dav. Mechanically, qhov no yog feem ntau ua tiav siv lub subtly bulged thiab frosted diffuser npog ntawm BR30 LED teeb, nyob rau hauv sib piv rau lub pob tshab, collimating lens ntawm ib tugPAR30 LED teeb.
 

Txheeb xyuas qhov tsim nyog lumens (lossis sib piv watts) xav tau

Feem ntau, koj yuav tsum xyuas kom meej tias thaum hloov koj lub teeb ci BR30 nrog BR30 LED, koj ua tiav qhov ci ci zoo li yav dhau los.
Tej zaum koj yuav inclined mus koom lub teeb ci nrog wattage; Lub teeb 40-watt pom tau tias ci dua li 60-watt teeb.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias watts suav cov hluav taws xob hluav taws xob tawm tswv yim, tsis yog tag nrho cov teeb pom kev zoo.
Txoj kev no yog ib qho siv tau ntawm kev kwv yees qhov ci, muab feem ntau cov qhov muag teeb pom kev zoo sib xws.
BR30 LED teebmuaj ntau dua efficiency piv rau incandescent BR30 qhov muag teev. Qhov no qhia tau hais tias watts tsis yog ib qho kev ntsuas zoo rau qhov ci.
Es tsis txhob tsom rau watts noj, ib tug yuav tsum ua ntej lub teeb tso zis, ntsuas nyob rau hauv lumens.
Tsis paub meej txog qhov xav tau lumens? Ib tug yuav kwv yees qhov yuav tsum tau ua raws li qhov ua ntej installation ua ntej hloov mus rauLEDs.
Qhov no tuaj yeem suav nrog kev kwv yees kev hloov pauv ntawm 10 lumens ib watt.
Lumens=[watts incandescent] × 10
Piv txwv li, 65W incandescent BR30 qhov muag teev tuaj yeem tso tawm qhov kwv yees lumen tso zis ntawm 650 lumens los ntawm kev muab 65W los ntawm 10.
Cov lumens suav yog qhia hauv cov khoom specs.
Cov neeg tsim khoom qee zaum suav nrog wattage sib npaug (piv txwv li, "Sib npaug rau 65W incandescent") rau cov neeg siv yooj yim. Tu siab, tsis muaj kev cai hais txog wattage equivalence thov, ua rau qee cov tuam txhab lag luam ua qee yam lenient hauv lawv cov lus sib cav rau kev lees paub qhov sib npaug wattage siab.
Txawm hais tias peb hais kom siv 10 lumens-ib -watt hloov pauv tau yooj yim, Energy Star cov qauv qhia tias qhov hloov pauv tau meej dua txawv nrog lub teeb lub wattage, xws li 10 lumens ib watt ntawm qis wattages mus rau 15.0 lumens ib watt ntawm ntau dua wattages. Rau cov teeb nrog lub zog ntawm 100 watts lossis siab dua, nws raug nquahu kom siv qhov hloov pauv loj dua raws li Energy Star cov cai.
Nco ntsoov tias cov kev hloov pauv no tsis zoo rau cov neeg ua haujlwm rau A-cov teeb pom kev zoo, ua raws li kev soj ntsuam tias cov teeb pom kev zoo ntawm cov teeb pom kev zoo feem ntau pom qhov ua tau zoo dua qub.
Cov lus hauv qab no nthuav tawm cov luminous tso zis sib npaug rau qhov sib txawv wattages hauv 5-watt increments:
40 watts=400 lumens * 45 watts=450 lumens * 50 watts=500 lumens * 55 watts=605 lumens

Xyuas kom tseeb tias lub kaum sab xis yog kwv yees li 120 degrees (dav dav dav).

Thaum kuaj xyuas cov specs ntawm aBR30 LED qhov muag teev, txheeb xyuas tias lub kaum sab xis yog kwv yees li 120 degrees, qee zaum hu ua "dav dej nyab" beam kaum sab xis.
Qhov tseem ceeb ntawm qhov no yog dab tsi?
Lub perceived brightness ntawm ib yam khoom yog feem ntau dictated los ntawm cov xov tooj ntawm lub teeb hais uas ntaus ib tug nto (illuminance, quantified nyob rau hauv lux). Lumens ntsuas qhov ntau npaum li cas ntawm lub teeb tawm ntawm lub teeb, txawm hais tias lawv tsis muaj kev nkag siab txog kev coj ntawm lub teeb ntawd.
Lub teeb lub teeb lub kaum sab xis yog ib qho tseem ceeb uas qhia txog kev tawg ntawm cov teeb pom kev zoo, thaum kawg cuam tshuam rau lub teeb pom kev thoob plaws ib cheeb tsam.
Peb piav qhia lub ntsiab lus ntawm no hauv peb cov ntawv tshaj tawm ntawm qhov sib txawv ntawm lumens thiab lux.
Kev hloov pauv tam sim ntawd rau lub kaum sab xis, xws li nqaim mus rau 60 degrees, tuaj yeem tsim teeb pom kev zoo "hotspots," uas ua rau qee qhov chaw zoo li ci ntsa iab heev thaum lwm tus nyob twj ywm dull.

Ntsuam xyuas lub teeb xim - Correlated Color Temperature (CCT) thiab Xim Rendering Index (CRI)

Incandescent BR30 teeb muaj kev xaiv me me hauv xim; yuav luag txhua tus qauv los ntawm txhua lub tuam txhab tau nthuav tawm tib xim kub (2700K) thiab xim zoo (100 CRI).
BR30 LED teeb muab ntau qhov ua tau rau xim kub thiab CRI, cuam tshuam cov txheej txheem xaiv kom pom qhov tsim nyog.
Xaiv 2700KBR30 LED teebrau xim kub.
Xim kub quantifies lub℃ntawm "daj" los yog "xiav" nyob rau hauv lub teeb lub xim.
2700K yog sib npaug rau cov xim ntawm cov teeb pom kev zoo ib txwm muaj . 3000K muaj lub ntsej muag xiav me ntsis, zoo li lub teeb halogen teeb, tseem khaws lub suab sov, txais tos daj.
4000K feem ntau hu ua "nruab nrab dawb" vim tias nws tsis muaj xim xiav lossis daj, tso nws ze ntawm qhov nruab nrab ntawm cov xim kub spectrum.
Txhua qhov kub siab tshaj 5000K yuav muaj xim xiav thiab tsis pom zoo rau kev siv hauv tsev, tab sis nws nquag nyiam rau kev kos duab thiab studio lub hom phiaj.
Teeb pom kev zoo rau koj qhov chaw nyob yog qhov kev txiav txim siab tiag tiag; Txawm li cas los xij, peb xav pib nrog 2700K BR30 LED qhov muag teev rau kev sim. Yog tias koj ntseeg tias nws tso tawm ntau dhau "daj" tint, koj tuaj yeem xav txog kev hloov mus rau 3000K. Nco ntsoov tias 3000K yuav ua haujlwm marginally "cooler" lossis "crisper" dua li lub teeb BR30 incandescent.
CRI: xaiv 90 lossis siab dua. Xim Rendering Index (CRI) tuaj yeem ua tau yooj yim rau kev nkag siab, vim nws tsis yooj yim pom meej thaum tsuas yog saib ib qho.BR30 LED teebncaj qha.
CRI yog tus nqi ntawm 0 txog 100 uas ntsuas qhov tseeb ntawm cov khoom zoo li nyob rau hauv illumination. Qhov qhab nia siab dua qhia qhov tseeb dua.
Qhov tseeb txhais ntawm qhov tseeb yog dab tsi?
Xav tias koj tab tom sim teeb ib daim duab. Ib tug impeccably precisionBR30 LED teebyuav ua rau cov artwork zoo tib yam rau nws cov tsos nyob rau hauv ib tug halogen noob.
Lub teeb qis CRI BR30 LED yuav ua rau cov duab kos tsis raug, ua rau cov xim tsis sib xws, ntxuav tawm, lossis tsis paub qhov txawv.
Qhov no txuas mus dhau paintings los yog artwork. Qhov pom kev zoo ntawm cov rooj tog lossis khoom noj yuav zoo li tsis muaj xim thiab dab yog tias lub teeb LED muaj qhov tsis txaus xim Rendering Index (CRI).
Tus nqi CRI txaus yog dab tsi?
Peb qhia kom tauBR30 LED qhov muag teevnrog qhov tsawg kawg nkaus Xim Rendering Index ntawm 90.
Txhawm rau txhim kho kev zoo nkauj, peb qhia CRI ntawm 95 lossis siab dua.
Yuav ua li cas thiaj paub tseeb CCT lossis CRI ntawm BR30 LED teeb? Yuav luag tag nrho cov tuam txhab lag luam tuaj yeem suav nrog cov ntaub ntawv no rau ntawm daim ntawv qhia khoom lossis pob.

Nws yog dimmableBR30 LED teebxav tau?

Lub teeb ci BR30 yog ib qho khoom siv yooj yim uas ua kom sov ib lub filament mus rau qhov kub siab (2700 Kelvin), uas ua rau lub teeb emissions. Dimming lub teeb yog qhov yooj yim heev; los ntawm kev txwv cov hluav taws xob tam sim no rau lub teeb, lub filament cools, li no txo ​​cov teeb pom kev zoo.
Feem ntau ntawm dimmer circuits feem ntau muab tso rau hauv qhov chaw nyob ua haujlwm raws li lub tswv yim no, hu ua TRIAC.
BR30 LED qhov muag teev yog qhov nyuaj, ua haujlwm raws li cov khoom siv hluav taws xob tiag. Yog tias tsis muaj kev sib koom ua ke ntawm cov hluav taws xob tshwj xeeb hauv lub teeb, tsis siv neeg compatibility nrog dimmer systems tsis tiav.
Dimming LED tsis raug xaiv raws li dimmable tuaj yeem ua rau tsis muaj kev cia siab flickering lossis buzzing suab nrov, thiab qee zaus, ua rau muaj kev phom sij.
Xyuas kom meej tias BR30 lub teeb raug cim raws li sib haum nrog dimmers yog tias lub dimmer haum yog xav tau dimmability.
