Koj puas tuaj yeem qhia qhov txawv ntawm lub teeb incandescent, lub teeb halogen, lub teeb fluorescent, lub zog- txuag lub teeb, thiab LED teeb?
Tam sim no muaj ntau yam teeb pom kev hauv khw. Thaum peb xaiv lub teeb, peb feem ntau tsis paub yuav pib qhov twg. Lub teeb twg haum rau peb? Lub teeb twg yuav tsum tau siv nyob rau hauv ib puag ncig sib txawv? Tom ntej no, kuv yuav muab cov lus qhia luv luv rau koj txog qee lub teeb pom kev zoo hauv khw.
1. Lub teeb ci
Lub teeb -emitting lub hauv paus ntsiab lus ntawm lub teeb incandescent yog kom sov lub filament mus rau lub incandescent lub xeev, thiab siv lub thermal tawg los emit ib tug hluav taws xob lub teeb qhov chaw uas emits pom lub teeb.
Nws yog hom teeb pom kev zoo uas peb tau siv thaum peb tseem hluas, uas yuav kub heev rau tes ntev, thiab feem ntau slammed lub filament, uas yog lub teeb incandescent. Tsawg dua 10 feem pua ntawm cov hluav taws xob hluav taws xob uas nws siv tau tuaj yeem hloov mus rau hauv lub teeb lub zog (piv rau 2 feem pua rau cov teeb pom kev zoo tib yam), thaum tus so yog poob li cua sov. Nyob rau tib lub sijhawm, qhov kub ntawm filament ntau dua, qhov ceev ntawm tungsten filament evaporates, ua rau lub neej luv dua rau feem ntau lub teeb ci. Yog li ntawd, txawm hais tias lub teeb incandescent muaj ntau yam zoo - lub teeb xim yog ze tshaj plaws rau cov xim ntawm lub hnub, cov xim rendering zoo, lub spectrum yog uniform thiab tsis obtrusive - tab sis cov khib nyiab ntawm lub zog yog loj. Txij li thaum pib xyoo 2007, tsoomfwv Australian tau ua tus thawj coj hauv kev tshaj tawm kev tshem tawm tag nrho cov teeb pom kev zoo hauv daim ntawv kev cai lij choj. Thaum pib, ntau tshaj kaum lub teb chaws thiab cheeb tsam tau ua tiav tso tawm lub teeb ci theem teeb pom kev zoo- tawm cov phiaj xwm. kuv lub teb chaws kuj tau maj mam ua ib theem-tshaj tawm txoj kev npaj txij li xyoo 2011. Txij lub Kaum Hli 1, 2016, muag thiab ntshuam lub teeb ci ntawm 15 watts thiab siab dua rau cov teeb pom kev zoo raug txwv.
Cov ntsiab lus: Yog tias koj xav siv lub teeb incandescent ua lub teeb ci, yuav muaj qhov nyuaj rau kev yuav khoom yav tom ntej.
2. Halogen teeb
Lub teeb halogen tuaj yeem pom tau tias yog qhov hloov kho tshiab ntawm lub teeb incandescent. Xa mus rau lub teeb halogen lossis halogen teeb, tseem hu ua tungsten halogen noob, quartz noob, yog ib qho txawv ntawm lub teeb incandescent. Lub hauv paus ntsiab lus yog txhaj cov roj halogen xws li iodine lossis bromine rau hauv qhov muag teev. Thaum qhov kub thiab txias, sublimated tungsten filament thiab halogen tau siv tshuaj lom neeg ua haujlwm, thiab cov tungsten txias yuav rov qab -solidify ntawm tungsten filament los tsim ib lub voj voog sib npaug kom tsis txhob tawg ntxov ntawm tungsten filament. . Yog li ntawd, halogen qhov muag teev ntev dua li qhov muag teev (yuav luag 4 npaug ntev), thiab vim tias cov filament tuaj yeem ua haujlwm ntawm qhov kub siab dua, lawv tau txais kev ci ntsa iab ntau dua, xim kub dua thiab ntau dua luminous efficiency.
Raws li kev hloov kho tshiab ntawm lub teeb incandescent, lub teeb halogen muaj tag nrho cov txiaj ntsig ntawm lub teeb ci, tab sis lub teeb halogen kuj tau txais qhov tsis zoo ntawm lub teeb incandescent: lub neej luv (txawm hais tias twb ntev dua lub teeb incandescent), tsis muaj luminous efficiency (txawm hais tias twb siab dua lub teeb incandescent. ), Tsis tas li ntawd, txij li lub teeb halogen kuj yog qhov hluav taws xob hluav taws xob, qhov kub ntawm lub teeb tseem siab heev thaum lub teeb pom kev zoo lossis tsuas yog tom qab lub teeb raug kaw, yog li nws tsis tuaj yeem kov nrog koj txhais tes kiag li.
Tsis tas li ntawd, ob qho tib si incandescent thiab halogen teeb muaj me me ntawm ultraviolet (UV) thiab infrared (IR) hluav taws xob teeb meem. Nws yog ib qho yooj yim los ua teeb meem ntawm daim tawv nqaij ntawm lub ntsej muag, ua ke nrog cov hluav taws xob ultraviolet, nws tuaj yeem ua rau muaj mob hnyav xws li hnub ci dermatitis.
Cov ntsiab lus: Yog tias koj xav siv lub teeb halogen ua lub teeb ci, koj xav tau yam tsawg kawg yog UV tiv thaiv kev kho mob - luv luv, nws yog qhov zoo tshaj plaws kom muaj frosted los yog ib nrab frosted thiab UV-resistant iav vaj huam sib luag rau lub teeb -emitting ib feem ntawm lub teeb taub hau.
3. Ordinary fluorescent teeb
Cov raj ntev peb siv thaum peb tseem yog menyuam yaus yog lub teeb fluorescent, kuj hu ua lub teeb fluorescent. Lub teeb fluorescent ib txwm muaj yog lub teeb qis - siab mercury lub teeb, uas siv qhov qis - siab mercury vapor los tso tawm ultraviolet rays tom qab tau energized, kom lub phosphor emits pom lub teeb, yog li nws belongs rau qhov tsawg. -pressure arc tawm lub teeb qhov chaw.
Cov raj fluorescent zoo ib yam yog coated nrog halogen phosphors thiab sau nrog sib xyaw ntawm argon thiab krypton-argon. Lub teeb xim yog: txias dawb hnub ci fluorescent raj, sov dawb hnub ci fluorescent raj. Piv nrog rau lub teeb incandescent, lub teeb fluorescent tsis kub thiab muaj ntau dua luminous efficiency, tab sis ob hom ntawm lub teeb fluorescent no muaj qis xim rendering kev ua tau zoo, thiab cov xim rendering Performance index R tus nqi yog tsawg dua 40. Ntau me dua hnub ci, tus qauv. tus nqi ntawm cov xim rendering Performance index R=100. Saib cov xim ntawm qhov chaw ntawm cov khoom xim, uas ua rau muaj xim cam. Cov xim yog cyan, grey, thiab xim yog dim thiab tsis ci. Ob hom teeb fluorescent no tsis siab -kev ua tau zoo thiab lub zog- txuag hluav taws xob qhov chaw, thiab tsis ua raws li cov kev cai ntawm lub teeb ntsuab.
Cov ntsiab lus: Tsis muaj zog txuag thiab kev tiv thaiv ib puag ncig, tsis pom zoo kom yuav.
Plaub, lub zog- txuag lub teeb (CFL teeb)
Lub npe CFL yog dav tsim txom rau hluav taws xob lub teeb qhov chaw uas tsis yog incandescent halogen lub teeb, xws li ubiquitous lo lus "LED CFL". Lub zog-txuag lub teeb hais ntawm no yog compact tri-xim hluav taws xob fluorescent teeb (lub npe hu ua CFL lub teeb txawv teb chaws), uas yog lub teeb fluorescent compact nrog nws tus kheej ballast.
Hauv kev nthuav dav, lub teeb CFL yog ib qho - tas zog compact zog - txuag lub teeb fluorescent. Lub raj, ballast thiab lub teeb lub hau ntawm lub teeb fluorescent zoo li no yog sib xyaw ua ke (lub ballast tau muab tso rau hauv lub teeb lub hau), thiab lawv tsis tuaj yeem muab tshem tawm tsuas yog ua kom puas tsuaj, yog li lawv hu ua "compact" fluorescent teeb. Txij li thaum tsis tas yuav ntxiv lub ballast, thiab lub voj voog tsav tsheb kuj tseem nyob hauv lub ballast, lub teeb fluorescent no kuj yog tus kheej - ballasted fluorescent teeb thiab lub teeb fluorescent sab hauv. Tag nrho lub teeb yog txuas ncaj qha mus rau lub zog hluav taws xob network los ntawm E27 thiab lwm tus tuav lub teeb, uas tuaj yeem hloov lub teeb hluav taws xob ncaj qha. Feem ntau ntawm cov teeb fluorescent no siv peb -xim phosphors ntawm lub ntiaj teb tsis tshua muaj, yog li lawv muaj lub zog- txuag lub zog, yog li lawv hu ua "zog- txuag lub teeb". Lub zog- txuag lub teeb me me, txuag lub zog dua li lub teeb incandescent, thiab muaj lub neej ntev dua li lub teeb incandescent. Txawm li cas los xij, qhov tsis zoo kuj tseem pom tseeb: raws li hom teeb pom kev zoo, mercury ntxiv rau lub teeb raj. Nyob rau hauv tsis muaj ib tug zoo recycling mechanism tam sim no, lub Environmental pollution tshwm sim tsis tau ignored. Tsis tas li ntawd, lub ballast siv nyob rau hauv lub zog- txuag lub teeb yuav ua rau qee yam hluav taws xob hluav taws xob thaum tsim hluav taws xob tam sim no.
Cov ntsiab lus: Nws muaj mercury thiab lwm yam khoom tsis zoo, uas ua rau muaj kev phom sij rau ib puag ncig thiab tsim qee yam hluav taws xob hluav taws xob. Nws tsis pom zoo kom yuav.
Tsib, LED teeb
LED yog lub ntsiab lus ntawm lus Askiv lub teeb emitting diode (lub teeb emitting diode). Lub teeb -emitting diode yog ib qho khoom siv hluav taws xob- lub xeev semiconductor uas tuaj yeem hloov hluav taws xob hluav taws xob rau hauv lub teeb pom kev, thiab nws tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb.
Lub plawv ntawm LED yog semiconductor nti, ib kawg ntawm nti yog txuas mus rau lub bracket, ib kawg yog qhov tsis zoo electrode, thiab lwm yam kawg yog txuas nrog lub zoo electrode ntawm lub hwj chim mov, kom tag nrho cov nti yog encapsulated. los ntawm epoxy resin. Lub semiconductor wafer muaj ob feem, ib feem yog P-hom semiconductor, nyob rau hauv uas lub qhov dominate, thiab lwm kawg yog N-hom semiconductor, qhov twg electrons feem ntau. Tab sis thaum ob lub semiconductors txuas nrog, P-N kev sib tshuam yog tsim los ntawm lawv. Thaum cov tam sim no ua rau lub wafer los ntawm cov hlau, cov electrons yuav raug thawb mus rau thaj tsam P, qhov twg cov electrons thiab qhov recombine, thiab ces emit zog nyob rau hauv daim ntawv ntawm photons, uas yog lub hauv paus ntsiab lus ntawm LED teeb emission.
Vim tias lub teeb LED tsis tsim hluav taws xob kub thiab hloov hluav taws xob rau hauv lub teeb lub zog ntau li ntau tau, LEDs feem ntau hu ua "LED zog- txuag lub teeb". Thaum yuav lub zog- txuag lub teeb, nco ntsoov paub qhov txawv ntawm ob lub teeb sib txawv, LED thiab CFL. Kuj tseem hu ua lub zog- txuag lub teeb, piv nrog CFL lub teeb, LED lub teeb yog ib puag ncig zoo thiab tsis muaj mercury thiab tuaj yeem siv dua thiab rov siv dua. Qhov no tej zaum yog ib qho tseem ceeb tsav tsheb rau lub teb chaws mus rau lub zog tsim LED teeb. LED teeb muaj ntau qhov zoo, feem ntau yog cov hauv qab no:
①Green ib puag ncig tiv thaiv: me me glare, tsis muaj hluav taws xob, tsis muaj teeb meem tshuaj raug tsim thaum siv.
② Lub neej ntev thiab kev ua haujlwm ruaj khov, tsis muaj qhov tsis txaus xws li hlawv yooj yim, thermal deposition, thiab lub teeb lwj ntawm cov filament.
③ Ntau qhov kev hloov pauv: LED lub teeb ci tuaj yeem siv lub hauv paus ntsiab lus ntawm liab, ntsuab thiab xiav peb lub ntsiab xim, nyob rau hauv kev tswj ntawm computer technology, tsim cov xim sib txawv, siv thiab xim kub.
Cov ntsiab lus: Muaj ntau qhov zoo, tab sis qhov tsis zoo yog tias tus nqi siab me ntsis siab dua li saum toj no - hais txog lub teeb, tab sis nyob rau lub sijhawm ntev, cov nqi hluav taws xob txuag kuj tuaj yeem rov qab tau sai.
