Hais txog yuav ua li cas LED teeb txawv ntawm cov niaj hnub, dab tsi los nrhiav thaum yuav thiab seb lawv puas zoo txaus los hloov tag nrho cov qij hauv tsev nrog lawv.

Yuav ua li cas LED qhov muag teev txawv ntawm lwm tus

Raws li lub npe qhia, lub teeb ci hauv LED teeb yog cov khoom siv hluav taws xob me me hu ua LEDs. Nyob rau hauv ib txwm incandescent teeb, lub teeb yog emitted los ntawm ib tug liab-kub hlau kauv. Hauv lub teeb txuag hluav taws xob, lub teeb yog tawm los ntawm phosphor uas yog siv rau sab hauv ntawm lub iav raj. Nyob rau hauv lem, lub phosphor glows nyob rau hauv qhov kev txiav txim ntawm ib tug gas paug.

Ua ntej txav mus rau qhov tseeb LED teeb, peb yuav luv luv txiav txim siab txog cov yam ntxwv ntawm txhua hom teeb.

Lub teeb incandescent Cov qauv yog yooj yim heev: ib tug kauv ua los ntawm refractory hlau yog tsau nyob rau hauv lub pob tshab iav qhov muag teev, los ntawm cov huab cua yog evacuated. Dhau los ntawm cov kauv, cov hluav taws xob tam sim no heats nws mus rau qhov kub siab, uas cov hlau ci ci ntsa iab.

Qhov zoo ntawm cov teeb no yog lawv cov nqi qis. Txawm li cas los xij, nws tau them nyiaj los ntawm qhov ua tau zoo sib npaug: tsawg dua 10% ntawm cov hluav taws xob siv los ntawm lub teeb pom kev zoo hloov mus rau qhov pom kev. Tus so yog siv tsis tau dissipated nyob rau hauv daim ntawv ntawm tshav kub - lub teeb tau kub heev thaum lub sij hawm ua hauj lwm. Tsis tas li ntawd, lub neej kev pab cuam ntawm lub cuab yeej yog luv heev, kwv yees li 1,000 teev.

Compact fluorescent teeb, los yog CFL (qhov no yog lub npe tiag tiag ntawm lub teeb txuag hluav taws xob), nrog tib lub teeb ci ntawm lub teeb, nws siv li tsib zaug hluav taws xob tsawg dua li lub teeb incandescent. CFLs kim dua thiab muaj ntau qhov tsis zoo uas tseem ceeb rau cov neeg siv khoom:

• ntev heev (ntau feeb) flare tom qab switching rau;
• lub teeb nrog nws nkhaus iav qhov muag pom unaesthetic;
• CFL lub teeb flickers, uas yog qaug zog rau lub qhov muag.

LED teeb muaj ob peb LEDs mounted nyob rau hauv tib lub tsev nrog ib lub hwj chim mov. Lub zog hluav taws xob yog qhov tseem ceeb: LEDs xav tau 6 lossis 12 V DC lub zog ua haujlwm, thiab 220 V AC lub zog hauv tsev siv hluav taws xob.

Lub teeb lub cev yog feem ntau ua nyob rau hauv daim ntawv ntawm ib tug paub "pear" nrog ib tug ntsia hlau puag. Ua tsaug rau qhov no, LED teeb tuaj yeem yooj yim ntsia tau rau hauv ib lub thawv tsis tu ncua.

Nyob ntawm cov LEDs siv, cov xim emitting ntawm LED teeb yuav txawv. Qhov no yog ib qho ntawm lawv qhov zoo.

	Lub teeb incandescent	Kev txuag hluav taws xob	LED
Cov xim hluav taws xob	Daj	Kub, nruab hnub	Daj, sov dawb, txias dawb
Kev siv fais fab	Loj	Nruab nrab: 5 npaug tsawg dua qhov muag teev	Tsawg: 8 npaug tsawg dua qhov muag teev
Lub neej	1 txhiab teev	3-15 txhiab teev	25-30 txhiab teev
qhov tsis zoo	Thaum tshav kub kub	Fragile, siv sij hawm ntev los flare	Tsawg zog siab tshaj plaws
Qhov zoo	Tus nqi qis, ua haujlwm hauv ntau yam kev mob	Tus nqi qis thiab ruaj khov	Yooj yim heev thiab ruaj khov

Qhov zoo ntawm LED teeb:

• tsawg zog noj - nyob rau nruab nrab, yim lub sij hawm tsawg dua incandescent teeb ntawm tib brightness;
• Lub neej ua haujlwm ntev heev - lawv ua haujlwm 25-30 lub sijhawm ntev dua li cov teeb pom kev zoo;
• yuav luag tsis tau sov;
• hluav taws xob xim - ntawm kev xaiv;
• ruaj khov illumination brightness thaum lub mov voltage fluctuates.

Lub ntsiab kom zoo dua ntawm LED teeb yog kev lag luam. Nws yog assumed tias vim tsis tshua muaj hluav taws xob noj thiab kev pab lub neej ntev, LED teeb yuav txo tau cov nqi teeb pom kev zoo.

Tus nqi ntawm LED teeb nyob rau lub sijhawm sau ntawv no yog kwv yees li peb zaug siab dua li cov pa. Yog li ntawd, nyob rau hauv cov nqe lus ntawm nyiaj txiag, lawv tig tawm mus rau 50-100 lub sij hawm ntau nyiaj txiag. Cov kev txuag no, tau kawg, yuav ua tiav yog tias lub teeb ncav cuag nws lub neej tau cog lus tseg thiab tsis hlawv tawm ntxov ntxov.

Disadvantages ntawm LED teeb txwv lawv txoj kev:

• Lub teeb tsis sib xws - lub zog hluav taws xob ua rau hauv lub cev ua kom lub teeb ci ntsa iab;
• lub teeb matte zoo li dab tuag hauv iav thiab siv lead ua teeb;
• lub ci ci ntawm lub ci, raws li txoj cai, tsis tuaj yeem hloov pauv siv lub dimmer;
• tsis haum rau kev siv nyob rau hauv qis heev (tej) thiab siab (hauv chav chav, saunas) kub.

Tej yam uas yuav tsum tau xav txog thaum xaiv lub teeb LED

LED qhov muag teev muaj ntau yam ntxwv. Qhov no ua rau txoj haujlwm ntawm kev xaiv txoj cai nyuaj dua. Cia peb saib seb qhov txawv yam ntxwv txhais li cas.

Muab hluav taws xob

Yog tias muaj qhov tsis ruaj khov nyob hauv koj chav tsev lossis lub tsev, koj yuav tsum xaiv cov teeb uas muaj peev xwm ua haujlwm nyob rau hauv ntau qhov hluav taws xob. Qhov no yeej ib txwm qhia ntawm lub ntim. Tsis zoo li cov teeb ci incandescent, LED teeb ntawm qhov txo qis hluav taws xob hlawv li ci ntsa iab li ntawm qhov qub voltage.

Cov xim hluav taws xob

Xim yog tus cwj pwm los ntawm cov xim kub, uas ntsuas hauv kelvin: raws li xim kub nce, lub teeb hloov ntawm daj mus rau xiav. Feem ntau, cov xim ntawm cov hluav taws xob tau qhia rau ntawm lub ntim thiab lub teeb vaj tsev nyob hauv qib thiab hauv cov lus:

• sov (2,700 K) - kwv yees li sib raug rau cov hluav taws xob ntawm lub teeb incandescent;
• sov dawb (3,000 K) - pom zoo rau thaj chaw nyob;
• txias dawb (4,000 K) - rau chaw ua haujlwm thiab chaw ua haujlwm; ze rau nruab hnub.

Muaj cov teeb nrog cov xim hloov tau: thaum koj hloov hom, qhov emission spectrum ntawm xws li lub teeb hloov.

Nws yuav tsum tau borne nyob rau hauv lub siab hais tias muaj coob tus neeg tsis pom lub xiav ib feem ntawm lub spectrum zoo, yog li ntawd lub teeb txias ntawm lub teeb yuav zoo li dim rau lawv. Yog li, yog tias koj txiav txim siab los teeb tsa lub teeb nrog lub spectrum txias hauv koj lub tsev, xaiv lawv nrog cov npoo ntawm lub zog.

Hwj chim

Lub ntim ntawm LED teeb qhia lawv cov luminous flux thiab lub zog ntawm incandescent teeb ntawm zoo li brightness. Lub zog siv hluav taws xob tiag tiag ntawm LED teeb yog qhov nruab nrab 6-8 npaug tsawg dua. Piv txwv li, 12W LED teeb ci ci zoo li lub teeb 100W ib txwm muaj. Qhov piv no tuaj yeem siv thaum xaiv lub teeb LED los hloov lub teeb incandescent.

Txawm li cas los xij, qhov tsis txaus siab xav tsis thoob yuav nyob tos koj ntawm no: lub zog tshaj tawm yuav tsis sib haum rau qhov tseeb, thiab lub teeb yuav ci qis dua li qhov xav tau.

Tsis tas li ntawd, qhov ci ntsa iab ntawm LEDs txo qis lub sijhawm. Nws muaj peev xwm hais tias lub teeb yuav tsum tau hloov ntev ua ntej lub sij hawm tas sij hawm ntawm nws cov kev pab cuam lub neej vim hais tias nws pib ci heev tsis muaj zog.

Lwm cov ntsiab lus tseem ceeb

• Qhov ntev. LED teeb yog me ntsis loj dua qhov zoo sib xws cov teeb incandescent. Yog li ntawd, cov teeb me me yuav tsuas tsis haum.
• Yog tias koj lub teeb dimmed, koj xav tau cov qij tsim nyog. Lub ntim yuav tsum qhia tias lub teeb yog adjustable.
• Cov xim rendering Performance index ntawm LED teeb yog tsawg, uas txhais tau hais tias lawv me ntsis distort qhov pom kev xaav ntawm cov xim. Qee zaum, xws li thaum thaij duab nrog lub teeb LED, qhov no tuaj yeem yog qhov tseem ceeb.

LED Switching Strategy

Cov peev nyiaj txuag yuav tsum tsis txhob ua rau koj poob koj lub taub hau. Tsis txhob maj khiav mus rau tom khw thiab yuav qhov muag teev rau txhua lub teeb hauv tsev ib zaug. Nws raug nquahu kom coj los ntawm ob lub hauv paus ntsiab lus.

1. Hloov tsuas yog qhov muag teev uas muaj wattage siab - 60 W lossis ntau dua. Cov nyiaj txuag los ntawm kev hloov cov qij qis qis yuav me me thiab tus nqi ntawm lub teeb tshiab yuav tsis them.
2. Hloov cov teeb nyob rau hauv cov teeb, lub sij hawm kub ntawm qhov ntev tshaj plaws thaum nruab hnub: piv txwv li, nyob rau hauv chandeliers nyob rau hauv cov chav nyob. Nws ua rau tsis muaj kev txiav txim siab hloov lub teeb pom kev zoo hauv qee chav rov qab, lub teeb nyob rau hauv uas tau taws los ntawm ib ntus thiab ib lub sijhawm luv luv.

Tsis txhob cia siab tias kev siv hluav taws xob yuav txo qis heev.

Cov neeg siv hluav taws xob tseem ceeb hauv lub neej niaj hnub yog txhua yam khoom siv cua sov: hlau, hluav taws xob, lub tshuab ntxhua khaub ncaws, thiab tshwj xeeb tshaj yog lub qhov cub hluav taws xob. Raws li ntau tus neeg xam phaj, cov nqi hluav taws xob tom qab hloov mus rau LED teeb txo qis li 15-25%.

Lwm cov lus qhia: tsis txhob yuav ntau lub teeb ntawm tib lub hom ib zaug, ua ntej coj ib los yog ob qho rau ib qho qauv. Qhov tseeb yog tias cov teeb nrog tib xim kub los ntawm cov tuam txhab sib txawv tuaj yeem sib txawv heev hauv lawv lub teeb ci. Yuav ua li cas yog lub spectrum ntawm cov teeb tshwj xeeb no yuav tsis kaj siab rau koj? Zoo dua los sim.

Xaus

LED teeb, piv rau cov teeb pom kev zoo, yog cov teeb pom kev zoo tshiab.

Ob peb xyoos dhau los lawv yog ib qho khoom kim heev technical novelty, tab sis niaj hnub no lawv cov nqi yog twb muab piv rau cov nqi ntawm lwm hom teeb. Raws li rau cov yam ntxwv, LED teeb pom kev zoo dua rau yav dhau los teeb pom kev zoo ntawm lawv. Qhov kev txiav txim tsis meej: kev hloov mus rau LED teeb yog qhov ncaj ncees.
