Ua ntej, thaum xaiv lub chandelier, peb pib los ntawm qhov luaj li cas ntawm chav tsev thiab tus naj npawb ntawm qhov muag teev. Tam sim no qhov ntau yog dav dua. Ntxiv nrog rau lub teeb incandescent, ntawm lub rhawv ntawm cov khw muag khoom koj tuaj yeem yuav cov teeb uas sib txawv kiag li tsis yog hauv cov duab xwb, tab sis kuj yog lub hauv paus ntsiab lus ntawm kev ua haujlwm. Lub teeb txuag hluav taws xob, vim nws cov yam ntxwv txhim kho, yog nyob rau hauv qhov chaw hwm. Nws tso cai rau koj txuag kev siv hluav taws xob.
Lub teeb txuag hluav taws xob yog dab tsi? Cia peb sim nkag siab txog lub tswv yim no. Ua ntej ntawm tag nrho cov, lawv txawv los ntawm kev nce lub teeb tso zis, uas yog, lawv muab tib lub illumination, tab sis tib lub sij hawm siv tsawg zog. Lawv kuj muaj lub neej ua haujlwm ntev dua. Peb paub zoo tshaj plaws yog lub teeb txuag hluav taws xob fluorescent. Tab sis tam sim no, nrog rau cov thev naus laus zis no, lwm cov kev xaiv tau pom lawv daim ntawv thov. Lawv txawv tsis tsuas yog nyob rau hauv tsos, tab sis kuj nyob rau hauv txoj kev ntawm kev tua. Qhov no suav nrog LED thiabCov khoom siv halogen. Tag nrho cov ntawm lawv yuav txawv nyob rau hauv daim ntawv ntawm lub qab nthab, qhov loj thiab hom ntawm lub hauv paus, nyob rau hauv cov xim. Tab sis lawv muaj ib txoj hauj lwm - txuag hluav taws xob.
Lub teeb incandescent ib txwm rau peb yog maj mam poob nws txoj haujlwm. Nws tau hloov los ntawm kev siv tshuab niaj hnub. Thaum pib, nws yog lub teeb txuag hluav taws xob fluorescent. Maj mam, nws cov yam ntxwv tau txhim kho, kev xaiv compact pib siv rau cov tsev nyob. Ntawm no, ua tsaug rau lub xub ntiag ntawm lub tshuab hluav taws xob, qhov zoo ntawm lub ci tau zoo tuaj, nws muaj peev xwm khiav tawm ntawm lub suab nrog rau hauv daim ntawv ntawm buzzing. Tab sis qhov ntev ntawm cov khoom siv no tseem loj dua li cov diode lossis halogen sawv daws yuav. Tsis tas li ntawd, lub xub ntiag ntawm mercury yuav tsum muaj cov txheej txheem pov tseg tshwj xeeb. Qhov no tuaj yeem taug qab hauv cov lag luam loj, tab sis nyob rau hauv cov xwm txheej hauv tsev nws tsim kev tsis yooj yim.
Kev txuag hluav taws xob halogen teeb txais kev siv thev naus laus zis thev naus laus zis. Lub xub ntiag ntawm halogens hauv, xws li bromine thiab iodine, tau tshwm sim hauv lub npe. Lwm qhov tseem ceeb yog kev siv cov iav kub-resistant, uas tuaj yeem tiv taus qhov kub thiab txias. Lawv cov thev naus laus zis tsim zam zam kev siv mercury, yog li lawv muaj kev nyab xeeb dua thiab zoo ib puag ncig.
LED lub teeb txuag hluav taws xob yog qhov yooj yim dua rau qhov no. Lawv tag nrho hloov peb li niaj zaus version ntawm teeb pom kev zoo. Feem ntau lawv tau muab nkag rau hauv lub teeb tiav, uas yog tsim tshwj xeeb rau cov cuab yeej zoo li no. Cov teeb pom kev zoo li no ua haujlwm tau ntev,thaum noj me me ntawm lub zog. Ntau lub teeb yog tsim rau cov kev xav tau sib txawv. Cov no tuaj yeem yog cov kev xaiv rau kev teeb tsa ntawm lub qab nthab lossis LED sawb, uas zoo dua zais tom qab eaves. Koj tuaj yeem siv phab ntsa mount lossis tsom teeb ntawm lub qab nthab.
Thaum xaiv lub teeb rau koj tus kheej, xyuam xim rau lub hauv paus, kev phooj ywg ib puag ncig ntawm cov ntaub ntawv thiab xim ntawm cov spectrum uas nws muab thaum qhib. Rau chav nyob, nws tuaj yeem yog lub teeb dawb ci, tab sis rau ib chav me me, nws yog qhov zoo dua los siv lub suab daj lossis xiav. Nyob rau hauv lub xyoo tom ntej, nws yog npaj kom tsis txhob tsim cov incandescent teeb. Txhawm rau npaj rau qhov kev txiav txim siab no, tam sim no koj yuav tsum xaiv rau koj tus kheej qhov kev xaiv uas lub teeb txuag hluav taws xob yuav hloov tau zoo rau Ilyich lub teeb teeb rau koj.
