Yog tias nrog cov teeb pom kev zoo tib yam txhua yam tsis muaj qhov yooj yim dua: lawv tsuas yog sib txawv ntawm lub zog thiab cov duab ntawm lub hauv paus, ces cov LED uas hloov lawv muaj ntau tus yam ntxwv.

Cov yam ntxwv ntawm LED teeb

Lub teeb ntws

Lub ci ci ntawm lub teeb ci LED yog tus cwj pwm los ntawm cov luminous flux, uas ntsuas hauv lumens (lm, lm). Yuav ua li cas ci ntsa iab koj xav teeb lub chaw ua haujlwm lossis chav tsev nyob ntawm koj. Tab sis sim ua raws li cov lus pom zoo ntawm SNiP:

Chav tsev	Lub teeb pom kev zoo (lm / sq. M)
Chav pw, chav ua noj	150
Cov me nyuam chav	200
chav dej, chav dej	50
General office	300
Kev kos duab	500

Txhawm rau txiav txim siab lub zog ntawm lub teeb thiab lawv tus lej, siv lub rooj. Nws kuj tseem qhia txog kev sib txuas lus ntawm cov teeb pom kev zoo li niaj zaus rau cov LED uas hloov lawv.

Luminous flux (lm)	LED teeb (W)	Teeb pom kev zoo (W)
250	3	25
400	5	40
650	8	60
1 300	14	100
2 100	22	150

Lub rooj qhia tau hais tias lub zog tsawg npaum li cas LED teeb siv. Qhov no yog ib qho ntawm cov laj thawj tseem ceeb rau lawv qhov chaw.

Xim spectrum

Lub luag haujlwm tseem ceeb sib npaug hauv kev xaiv lub teeb yog ua si los ntawm cov xim ntawm cov emission flux. Lub luag haujlwm rau nws yog xim kub, uas ntsuas hauv degrees Kelvin (K). Qhov qis dua qhov ntsuas no, qhov sov dua lub teeb yuav yog.

Xim kub (K)	Duab ntxoov ntxoo
2 700–2 800	sov daj
3 000	sov dawb
4 000	nruab nrab dawb
6 000	txias dawb

Cov ntxoov daj yog suav tias yog qhov nyiam tshaj plaws rau lub tsev: lawv pab kom so thiab so. Lub teeb sov sov yog pom zoo rau chaw ua haujlwm ib puag ncig. Nws ntseeg tias yuav txhim khu kev ua tau zoo. Thiab cov teeb nrog lub teeb txias dawb yog npaj rau cov chav tsis nyob hauv tsev.

Voltage range thiab xim rendering index

Yog tias cov teeb pom kev zoo tib yam uas tsis muaj qhov ci ntsa iab ua haujlwm ntawm qhov hluav taws xob ntawm 220 V, tom qab ntawd rau feem ntau cov teeb ci LED rau cov hluav taws xob ruaj khov, txawm tias tus nqi qis dua yog txaus. Ntawd yog, cov tswv ntawm cov teeb no yuav tsis pom qhov hluav taws xob poob hauv lub mains.

Thaum muas, sim xaiv qhov voltage ntau nrog qhov loj tshaj qhov sib txawv ntawm qhov tseem ceeb.

Cov xim rendering Performance index txiav txim siab li cas ib txwm xim ntawm cov khoom yuav kis tau nyob rau hauv lub teeb ntawm ib lub teeb. Nws yog qhia los ntawm CRI (xim rendering Performance index) lossis Ra parameter. Qhov siab dua CRI, qhov ntau dua qhov ntuj pom cov khoom yuav pom.

Hauv thaj chaw nyob, nws raug nquahu kom siv lub teeb nrog qhov ntsuas tsawg kawg yog 80 CRI lossis Ra.

Scattering lub kaum sab xis

LEDs yog tsim nyob rau hauv xws li ib txoj kev uas lawv muaj peev xwm ci tsuas yog nyob rau hauv pem hauv ntej ntawm lawv tus kheej: ib feem me me ntawm lub teeb yog deflected rau sab. Yog li ntawd, xyuam xim tsis tau tsuas yog rau lawv tus lej, tab sis kuj yuav ua li cas lawv nyob. Lub scattering lub kaum sab xis yuav ncaj qha nyob ntawm qhov no. Rau cov qauv sib txawv ntawm lub teeb, nws tuaj yeem yog 30 txog 360 degrees.

Ripple ntawm lub teeb

Lub teeb tsis zoo feem ntau pulsate. Nws yog qhov tsis pom ntawm tib neeg lub qhov muag, tab sis tuaj yeem cuam tshuam tsis zoo rau lub paj hlwb thiab ua rau pom kev tsis pom kev.

Yuav cov teeb nrog lub ripple ntau yam tsis ntau tshaj 5-15%.

Kev pab lub neej thiab chaw tsim khoom

LED qhov muag teev muaj qhov nruab nrab lifespan ntawm 10,000 txog 50,000 teev. Qhov tseeb yog qhov nyuaj heev los tsim, vim tias cov thev naus laus zis tau txhim kho los ntawm ib hnub rau ib hnub, kev pabcuam lub neej tsuas yog suav nrog hauv kev xav.

Lub warranty rau cov teeb no yog muab los ntawm 1 mus rau 5 xyoo thiab nyob ntawm cov chaw tsim khoom. Nws yog lub luag haujlwm ntawm lub khw los hloov lub teeb yog tias nws ua tsis tiav thaum lub sijhawm lav.

Niaj hnub no muaj ntau ntau manufacturers ntawm LED technology. Ntxiv mus, tsis yog txhua tus ntawm lawv qhia cov ntaub ntawv txhim khu kev qha txog lub teeb ntawm lub ntim. Koj tuaj yeem paub txog qhov ntsuas qhov tseem ceeb ntawm lub teeb tshwj xeeb uas siv cov kev pabcuam kuaj lamptest.ru.

Nws muaj ntau yam kev tshuaj xyuas, cov khoom thiab cov kev ntsuam xyuas ywj pheej ntawm LED cov khoom. Ntawm no koj tuaj yeem nrhiav tsis tau txhua yam ntawm cov qauv uas koj nyiam, tab sis kuj xaiv lub teeb tshwj xeeb rau koj cov kev xav tau: ua qhov no, qhia qhov tsim nyog tsis thiab nias lub pob "Qhia".

Yuav ua li cas xaiv qhov zoo LED teeb

Txhawm rau xaiv lub teeb uas yuav tsim teeb pom kev zoo, yuav siv sijhawm ntev, yuav tsis ua mob rau koj txoj kev noj qab haus huv thiab yuav txuag tau zog, siv cov lus qhia hauv qab no.

1. Cov xim spectrum ntawm lub teeb rau ib chav tsev yuav tsum tsis txhob ntau tshaj 3000 K. Yog hais tias koj xav tau ib lub teeb rau lub chaw ua hauj lwm, xaiv qhov kub ntawm 4000 K. Teeb ntawm 6000 K thiab saum toj no yuav tsum tau siv nyob rau hauv cov chav tsev hluav taws xob nkaus xwb.
2. Xaiv lub teeb nrog qhov voltage ntawm 110-230 V.
3. Xim rendering Performance index yuav tsum yog tsawg kawg yog 80 CRI.
4. Lub teeb ripple yuav tsum tsis pub tshaj 15%. Koj tuaj yeem tshawb xyuas nws hauv lub khw yooj yim: ntsia hlau qhov muag teev rau hauv lub hauv paus thiab nqa lub koob yees duab smartphone rau nws. Yog hais tias lub ripple siab, qhov screen yuav flicker.
5. Nco ntsoov xyuas seb lub teeb puas ua haujlwm zoo. Yuav luag txhua lub khw muag khoom hluav taws xob muaj qhov kev xaiv no.
