Incandescent: hom

Lub teeb yog pab kiag li lawm siv los taws lub chaw thiab tsim ib co teeb qhov chaw. Lawv txawv nyob rau hauv zoo, loj, me, muaj peev xwm, hom thiab par nqi ntawm cov voltage siv, thiab ib tug qauv ntawm cov ua teeb pom kev zoo. Cov feem nrov yog cov tsoos incandescent teeb. Nyob rau hauv tas li ntawd mus rau nws siv halogen, fluorescent, lub zog txuag teeb, neon, xenon, quartz thiab lwm yam kev teeb.

Tam sim no incandescent teeb tej zaum yuav muaj ib tug txawv lub hwj chim, luaj li cas thiab kev khiav hauj lwm voltage. Cov pab kiag li lawm cov txheej txheem raws li nram no. Lub iav teeb yog ib tug hlau arc (feem ntau tungsten), los ntawm kev uas hluav taws xob tam sim no ntws. Thaum lub sij hawm tso cai ntawm lub qhov hluav taws xob nws heats li, thiab incandescent teeb pib emit loj nyiaj ntawm tshav kub thiab lub teeb lub zog. Lub ntsiab disadvantage ntawm no ntaus ntawv yog faib ib tug loj npaum li cas ntawm tshav kub.

Thaum hloov cov ntaus ntawv tam sim ntawd tom qab switching tawm los yog nyob rau hauv tus txheej txheem ntawm hlawv koj yog hais tias koj tsis txhob siv kev tiv thaiv. Nyob rau hauv tas li ntawd, lub teeb yuav siv tsis tau nyob rau hauv lub teeb, uas yog muaj raws qhov theem ntawm kub. Piv txwv li, nyob rau hauv hmo ntuj teeb yuav tsum tsis txhob yuav ib tug incandescent teeb 100 watts. Txawm li cas los, pab kiag li lawm thiab muaj ntau yam zoo. Firstly, nws yog ib tug loj nphoo peev xwm (los ntawm 15 thiab mus txog rau 1000 watts). Nyob rau hauv tas li ntawd, lub teeb yuav tsum powered los ntawm txawv voltage qhov chaw (AC los yog DC, los ntawm 1 mus rau 240 volts). Lub teeb tej zaum yuav diffusing thiab pob tshab noob.

Halogen teeb yog zoo ib yam li lawv cov counterparts, tab sis lawv cov flasks tam sim no khub bromine los yog iodine. Ib me ntsis kev txhim kho yuav ua rau kom lub teeb tso zis thiab ua rau kom lub neej ntawm lub ntaus ntawv ob zaug. Tus so yog li ib txwm tshiab.

Incandescent teeb lumens kuj muaj ib cov roj uas, ua tsaug rau ib tug tshwj xeeb txheej (phosphors) ua tus pom teeb tawg tom qab tso cai ntawm lub tam sim no therethrough. Qhov kom zoo dua ntawm cov pab kiag li lawm yog tus muaj zog mov voltage nce mus txog 380 volts. Tsis tas li ntawd muaj ib tug tsawg cua sov kub (txog li 40 degrees) hauv cov kev ntaus ntaub ntawv, thiab lawv pab no muaj nuj nqis dua lub sij hawm.

Fluorescent teeb yog tsuas yog siv nyob rau hauv qhuav tej yam kev mob rau lub teeb pom kev zoo uas muaj thaj chaw, txoj kev teeb uas yog raws li nyob ze rau ntuj.

Txuag teeb yog ib tug ntaus ntawv uas tau txo hwj chim noj. nws yog ib lub paug ntawm lawv tsim. Qhov no ntaus ntawv siv eighty feem pua tsawg zog dua ib qho teeb, nrog lifespan mus txog rau 5 lub sij hawm. Nyob rau hauv tas li ntawd, lub zog txuag teeb tsis muaj cua sov. Lub ntsiab disadvantage yog lawv kuj qeeb thiab cov kev siv ntawm tus nqi. Dua li no, lawv yog nkag mus rau hauv muaj koob meej ntawm tau txais kev pab.

UV teeb thiab quartz yog siv nyob rau hauv tej cheeb tsam ntawm tib neeg kev ua si. Piv txwv li, nyob rau hauv cov tshuaj quartz ua bactericidal muaj nuj nqi thiab yog siv los kho cov neeg mob. UV siv nyob rau hauv forensic science, cov lag luam, thiab nyob rau hauv solariums kom tau ib tug tan.
