Classification Ntawm Teeb
Lub teeb incandescent
Xyoo 1909, tus kws tshawb fawb Asmeskas Corrich tau tsim cov tungsten filament los txhim kho lub ci ci thiab lub neej ntawm lub teeb incandescent. Lub filament nyob rau hauv lub khob qhov muag teev yog rhuab los ntawm kev siv hluav taws xob, uas ua rau lub teeb ci uas cov filament tsim thermal tawg thiab emits lub teeb. Lub kaus mom lub teeb yog qhov kev sib txuas hluav taws xob thiab cov khoom siv sib txuas ntawm lub teeb incandescent. Raws li daim ntawv thiab lub hom phiaj, nws tuaj yeem muab faib ua cov ntsia hlau hom teeb lub hau, tsom teeb lub hau thiab lub hau tshwj xeeb. Feem ntau siv nyob rau hauv thaj chaw yooj yim teeb pom kev zoo thiab teeb pom kev zoo, nws muaj qhov zoo ntawm kev yooj yim installation, pib tam sim ntawd, thiab tus nqi qis. Nws muaj ntau yam kev ua haujlwm voltage, los ntawm ob peb volts muab los ntawm lub roj teeb mus rau lub mains voltage, uas yog pheej yig thiab tsis xav tau ntxiv circuits. Nws cov ntawv thov tseem ceeb yog lub teeb pom kev zoo hauv tsev thiab qhov chaw uas xav tau kev ua haujlwm qis qis, xws li teeb nyem thiab lub teeb pom kev zoo. Tsuas yog 10 feem pua ntawm cov khoom siv hluav taws xob hloov pauv mus rau lub teeb pom kev zoo, thiab lub neej ntev li ntawm kaum teev mus rau ntau txhiab teev.
Tungsten halogen teeb
Lub invention ntawm halogen tungsten teeb nyob rau hauv 1959 coj lub technology ntawm incandescent teeb mus rau ib tug tshiab theem thiab nce lawv lifespan. Piv rau halogen dawb incandescent teeb nrog tib lub zog ntsuas, lub teeb halogen tungsten muaj qhov ntim me dua thiab tso cai rau kev ntim cov roj hnyav (ntau dua) ntawm kev kub siab. Cov kev hloov no tuaj yeem ua rau lub neej ntev lossis txhim kho lub teeb pom kev zoo. Ib yam li ntawd, tungsten halide teeb kuj tseem tuaj yeem txuas ncaj qha rau lub zog hluav taws xob yam tsis muaj kev tswj xyuas Circuit Court. Lub neej ua haujlwm ntawm lub teeb pom kev zoo tib yam yog 1000 teev, thiab lub teeb halogen tungsten yog ib nrab ntev dua nws, thiab cov luminous efficiency yog nce 30 feem pua. Tungsten halide teeb yog dav siv nyob rau hauv lub tsheb teeb pom kev zoo, projection systems, tshwj xeeb tsom teeb, tsis tshua muaj nqi dej nyab teeb, theem thiab studio teeb pom kev zoo thiab lwm yam sij hawm uas yuav tsum tau ntau compact, yooj yim thiab ua tau zoo tshaj cov uas tsis yog-halogen incandescent teeb.
Fluorescent teeb
Lub teeb fluorescent tau tshwm sim hauv xyoo 1940. Lawv siv lub hauv paus ntsiab lus ntawm cov pa tawm los tsim lub teeb lub zog. Vim hais tias lub teeb emissions feem ntau yog ultraviolet thiab tsawg infrared tawg, lub luminous efficiency yog siab dua li ntawm cov teeb incandescent. Lub teeb no yuav txuag tau 75 feem pua ntawm lub zog thiab ua kom lub neej ua haujlwm tau los ntawm 8-10 zaug es tsis txhob siv cov roj teeb incandescent. Tam sim no, cov teeb fluorescent siv los ntawm tib neeg feem ntau suav nrog cov teeb fluorescent, high-lumen single-ended fluorescent teeb, thiab lub teeb txuag hluav taws xob (cov teeb fluorescent compact), uas tau siv dav thiab ua lag luam thiab muaj teeb pom kev zoo. Feem ntau siv nyob rau hauv chaw ua hauj lwm, khw malls, lub tsev loj thiab lwm yam pej xeem vaj tse, nws muaj qhov zoo ntawm ntau lub teeb xim, siab illumination thiab kev lag luam. Los ntawm kev tsim kho tshiab, kev txhim kho phosphor thiab kev siv hluav taws xob tswj hluav taws xob, kev ua haujlwm ntawm lub teeb fluorescent tau txhim kho tsis tu ncua.
Low-pressure sodium teeb
Chav teeb pom kev tshwm sim thaum muaj ntau yam ntawm vapor kaw hauv cov iav raj emit lub teeb los ntawm hluav taws xob tam sim no. Chav teeb muaj xws li mercury vapor teeb thiab sodium vapor teeb. Lub teeb pom kev zoo yog qhov siab tshaj plaws, tab sis tsuas yog emits monochromatic daj lub teeb, uas ua rau nws tsis yooj yim sua kom paub qhov txawv ntawm ntau yam xim nyob rau hauv cov teeb pom kev zoo. Cov ntawv thov tseem ceeb yog: txoj kev teeb pom kev zoo, teeb pom kev nyab xeeb thiab kev siv sab nraum zoov hauv cov xwm txheej zoo sib xws. Nws cov luminous efficiency yog ob zaug ntawm lub teeb fluorescent thiab 10 npaug ntawm halogen tungsten teeb. Piv nrog cov teeb fluorescent, lub raj xa tawm ntawm lub teeb qis sodium teeb yog lub raj ntev, uas feem ntau yog khoov rau hauv "U" zoo li. Lub raj xa tawm tau muab tso rau hauv lub tshuab nqus tsev sandwich sab nrauv iav plhaub, uas yog coated nrog cov txheej txheem infrared kom ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab kev ua haujlwm siab tshaj plaws.
