Kev lag luam teeb pom kev zoo tau txhim kho sai. Nws zoo nkaus li tias lub teeb txuag hluav taws xob tau tshwm sim tsis ntev los no. Thaum xub thawj, cov neeg siv khoom raug tshem tawm los ntawm lawv cov nqi siab, muaj cov mercury, thiab qhov ntxoov ntxoo txawv txawv. Tam sim no lawv tau siv nyob txhua qhov chaw, thiab nyob rau hauv cov teb chaws Europe, cov pa taws tswm ciab yog qhov nyuaj rau nrhiav. Vim li cas lawv thiaj zoo thiab txawv ntawm lawv cov thawj coj?
Ua ntej, lub npe "lub teeb txuag hluav taws xob" tsuas yog kev tshaj tawm xov xwm. Qhov tseeb, "tus neeg saib xyuas hauv tsev" yog lub npe hu ua fluorescent discharge teeb rau lub sijhawm ntev. Nyob rau hauv tag nrho, muaj ob hom xws li teeb: compact integrated thiab tsis integrated. Lawv txawv ntawm ib leeg tsuas yog nyob rau hauv lub xub ntiag los yog tsis muaj lub tshuab hluav taws xob pib. Cov kev sib xyaw ua ke muaj qhov pib ua haujlwm thiab lawv feem ntau yog nruab nrog lub hauv paus uas tso cai rau lawv siv los hloov cov teeb ci. Cov teeb hluav taws xob tsis sib xyaw ua ke tsis muaj thiab tsuas tuaj yeem ntsia tau rau hauv cov teeb pom kev zoo uas nws tau ua hauv (xws li rooj teeb, piv txwv).
Txawm li cas los xij, keeb kwm ntawm lub npe thiab kev tshaj lijLub subtleties ntawm tus tsim tsis zoo li nyiam cov neeg siv khoom. Rau nws, qhov zoo ntawm lub teeb, kev ntseeg siab thiab tus nqi ntawm cov khoom yog qhov tseem ceeb. Tab sis qhov no yog qhov uas feem ntau tsis ntseeg thiab tsis sib haum xeeb tshwm sim. Tom qab tag nrho, lub teeb txuag hluav taws xob yog kim kim dua li cov khoom siv hluav taws xob, thiab ntau tus xav tsis thoob: "Yuav ua li cas thiaj li yuav tau txais kev ncaj ncees?" Wb sim saib seb.
Lub teeb txuag hluav taws xob, yog, raws li tau hais tseg, tso pa tawm, haus 3-5 zaug hluav taws xob tsawg dua ib chav tsev ntawm lub teeb dua li cov teeb pom kev zoo. Meanwhile, lub built-in electronics (pib) ua rau lawv rhiab heev rau voltage tee thiab nquag on-off. Feem ntau, cov chaw tsim khoom, thaum xam cov sijhawm ua haujlwm ntawm lub teeb txuag hluav taws xob, xav tias nws yuav qhib thiab tawm ib hnub ib zaug. Qhov no piav qhia qhov tseeb tias lub neej kev pab cuam ntawm cov teeb no hauv chaw ua haujlwm yog ob mus rau peb zaug ntev dua nyob hauv tsev. Tsis tas li ntawd, koj yuav tsum paub tias lub teeb txuag hluav taws xob muaj lub sijhawm hu ua hluav taws kub (mus txog qhov ci ntsa iab tshaj plaws), uas tshwm sim tsuas yog tom qab 100-200 teev ntawm kev kub hnyiab. Tom qab ntawd, qhov ci ntsa iab tsis muaj zog thiab tom qab ib xyoos nws tuaj yeem txo mus rau 70% ntawm tus nqi tshaj tawm. Thiab tseem, yog tias lub teeb txuag hluav taws xob ua haujlwm tsawg kawg ib xyoos, nws yuav them tag nrho rau nws tus kheej, ob qho tib si ntawm kev txuag hluav taws xob thiab hais txog qhov xav tau ntawm cov teeb pom kev zoo uas yuav tsum tau yuav nyob rau tib lub sijhawm.. Rau kev sib piv: lub neej kev pab cuam ntawm 60 W incandescent teeb, raws li manufacturers, tsis ntau tshaj 1000 teev. Lub teeb txuag hluav taws xob 20 wattyog lav rau 4000 teev.
Raws li qhov zoo ntawm lub teeb, hais txog cov xim rendering thiab chromaticity, niaj hnub txuag hluav taws xob qhov muag teeb muaj ntau dua rau lawv cov neeg ua ntej. Lub teeb fluorescent kim siv tsib-band phosphor coj lub teeb ci kom ze li sai tau rau hnub ci hnub ci.
Ntxiv rau, ua tsaug rau cov thev naus laus zis niaj hnub no, nws tau dhau los ua cov teeb fluorescent nrog txhua xim, los ntawm daj mus rau ultraviolet. Txawm li cas los xij, tag nrho cov saum toj no tsuas yog siv rau kim (los ntawm $ 5) qauv. Lub teeb txuag hluav taws xob pheej yig dua yuav tsis ua raws li qhov kev cia siab, vim nws muab "lub teeb tsis zoo", thiab cov khoom siv tsis zoo siv hauv nws tsis tshua muaj cia nws kav ntev dua ib xyoos.
