Lub teeb qhov chaw hom Cov khoom tseem ceeb ntawm cov teeb yog dab tsi?
Lub teeb ci qhov chaw kuj yog qhov chaw teeb pom kev zoo, uas yog hais txog lub teeb pom kev zoo siv rau kev teeb pom kev sab hauv thiab sab nraum lub tsev. Yog li dab tsi yog hom teeb pom kev zoo? Cias muab, nws yog feem ntau muab faib ua peb pawg: thermal hluav taws xob lub teeb qhov chaw, roj paug lub teeb qhov chaw thiab semiconductor teeb qhov chaw. Yuav muaj ntau yam khoom. Dab tsi yog hom teeb ci tseem ceeb? Don'tsis txhawj, BENWEI LIGHTING nyob ntawm no los piav qhia rau sawv daws, cia's saib.
Lub teeb qhov chaw
Lub teeb ci qhov chaw hom:
Thermal radiation teeb qhov chaw
Nws yog tsim los ntawm kev siv lub hauv paus ntsiab lus ntawm radioluminescence thaum cov khoom yog rhuab mus rau qhov kub thiab txias. Hom teeb no muaj cov qauv yooj yim thiab yooj yim rau siv, thiab tuaj yeem siv tau thaum lub ntsuas hluav taws xob ntawm lub teeb yog tib yam li lub zog hluav taws xob.
Gas tawm lub teeb qhov chaw
Nws yog tsim los siv lub hauv paus ntsiab lus ntawm luminescence thaum muaj hluav taws xob tam sim no dhau los ntawm cov pa roj. Hom teeb no muaj kev ua haujlwm siab luminous, lub neej ntev, thiab ntau hom teeb xim.
Lub teeb ci semiconductor
Xws li phosphors uas emit lub teeb nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb, los yog semiconductor pn junctions kom emit lub teeb. Hom teeb no tsuas yog siv rau hauv qhov chaw uas yuav tsum tau teeb pom kev tshwj xeeb.
Lub teeb qhov chaw
Dab tsi yog cov khoom tseem ceeb ntawm lub teeb?
Lub teeb incandescent
Lub teeb incandescent yog nruab nrog tungsten filament, luminous efficiency yog 10-15lm / w, xim kub yog hais txog 2800K, xim rendering yog zoo, thiab lub neej nyob rau hauv 1000 teev. Tuam Tshoj muaj cov khoom lag luam sib txawv ntawm 15w txog 1000w. Muaj ob hom teeb tuav: ntsia hlau hom thiab bayonet hom. Nws yog feem ntau siv rau sab hauv tsev teeb pom kev zoo, thiab tseem tuaj yeem siv rau sab nraum zoov teeb pom kev zoo nrog cov kev xav tau qis dua. Reflective incandescent teeb emit directional teeb beams thiab muaj ib tug siab lub teeb lub zog siv tus nqi. Lawv feem ntau yog siv nyob rau hauv lub khw qhov rais, exhibition halls thiab qhov chaw uas xav tau kev tsom teeb.
Tungsten halogen teeb
Tungsten halogen teeb yog nruab nrog tungsten filaments thiab muaj ib qho nyiaj ntawm iodine thiab bromine los yog lawv cov tebchaw. Lub teeb tungsten halogen siv lub hauv paus ntsiab lus ntawm tungsten halogen voj voog tshuaj tiv thaiv, uas zoo heev txo cov evaporation ntawm tungsten filament thiab qib ntawm blackening ntawm lub noob. Lub luminous efficiency thiab rated lub neej ntawm halogen tungsten teeb yog siab dua li cov teeb incandescent. Tungsten halogen teeb feem ntau ua rau hauv cov raj me me, lub zog 35w ~ 1000w, xim kub 2700 ~ 3300k, zoo xim rendering, ntsuas lub neej txog li 1500 teev, ruaj khov luminous flux. Nws feem ntau yog siv rau sab hauv tsev teeb pom kev zoo.
Fluorescent teeb
Lub teeb fluorescent yog lub teeb pom kev zoo sab hauv tsev, thiab nws cov luminous efficiency yog ntau dua li cov teeb ci, feem ntau 30-60lm / w, thiab cov luminous efficiency siab tuaj yeem ncav cuag 90lm / w. Lub teeb xim ntawm lub teeb fluorescent yog nruab hnub, txias dawb thiab sov dawb. Lub teeb muaj xim fluorescent siab siv peb-xim-xim phosphors, xim rendering Performance index tuaj yeem ncav cuag 80 lossis ntau dua, thiab lub neej ntev yog 1500-5000 teev. Cov ballasts sib xws thiab pib yuav tsum tau nruab thaum siv. High-colour-rendering fluorescent teeb feem ntau yog siv rau cov teeb pom kev hauv kev luam ntawv thiab dyeing factories, tsev luam ntawv, khw malls thiab TV studios uas yuav tsum muaj xim zoo nkauj. Lub zog ntawm lub raj ncaj fluorescent teeb yog li ntawm 6w txog 40w, mus txog 125w. Lub teeb zoo li no yog qhov tsim nyog tshaj plaws rau kev teeb pom kev hauv tsev, cov khw loj thiab cov chaw ua haujlwm precision. Txhawm rau txhim kho cov teeb pom kev zoo, cov teeb tshwj xeeb zoo li lub teeb fluorescent (xws li cov teeb fluorescent ncig) tuaj yeem siv los ua lub teeb ci. Tshiab tsim compact zog-txuag fluorescent teeb nrog me me thiab siab luminous efficiency kuj lug siv nyob rau hauv tsev teeb pom kev zoo.
Lub teeb qhov chaw
Gas tso lub teeb
Lub ntsiab lus dav dav rau cov roj teeb hluav taws xob siv hluav taws xob siab, lub teeb hluav taws xob siab mercury, hlau halide teeb, thiab cov teeb hluav taws xob siab sodium. Hom teeb no muaj lub zog siab, siab luminous efficiency, lub neej ntev, compact qauv thiab me me. Lawv feem ntau yog siv rau sab nraum zoov teeb pom kev zoo hauv txoj kev, squares, chaw ua si, thiab lwm yam, nrog rau cov teeb pom kev zoo sab hauv tsev hauv nruab nrab thiab siab qab nthab factories, chaw ntau pob, auditoriums thiab cov khw muag khoom loj.
①High-pressure mercury teeb: suav nrog fluorescent high-pressure mercury teeb thiab self-ballasted high-pressure mercury teeb. Lub zog ntawm 50w mus rau 1000w, lub luminous efficiency yog 40-50lm / w, xim rendering Performance index yog 40-45, thiab rated lub neej yog 5000 teev.
②Metal halide teeb: zoo ib yam li lub teeb siab mercury, hlau halide ntxiv rau lub luminous raj, yog li cov luminous efficiency tau nce mus rau 60-120lm / w, xim rendering Performance index yog nce mus rau 60-85, thiab lub neej nyob. yog 7000-10000 teev.
③ High-pressure sodium teeb: high-pressure sodium vapor discharge teeb, lub teeb yog golden dawb, luminous efficiency siab li 90-140lm / w, xim kub yog li 2000K, xim rendering tsis zoo, xim rendering Performance index yog 20-25, lub neej nyob yog 12000 teev, thiab lub zog yog 35 ~ 1000w.
Tsawg-siab sodium teeb tsis tshua muaj siab sodium vapor discharge teeb, lub teeb yog ntshiab daj, luminous efficiency siab li 130-200lm / w, lub zog yog 18-200w, xim rendering tsis zoo, thiab nws yog haum rau txoj kev teeb pom kev zoo.
Semiconductor fluorescent teeb
Hauv kev txhim kho cov xim dawb lub zog LEDs, cov khoom siv yooj yim ntawm cov LEDs zoo tib yam thiab cov xim dawb LED yog sib xyaw, thiab qhov zoo ntawm cov LEDs zoo tib yam tau hloov pauv mus rau xim dawb LEDs. Nws yog yuam kev tias lub neej kev pab cuam thiab luminous efficiency ntawm dawb xim LEDs yuav zoo li zoo tib yam LEDs, nws luminous efficiency yog overestimated, thiab nws muaj nuj nqi yog deified nyob rau hauv lub teb ntawm hluav taws xob lub teeb qhov chaw.
Cov lus saum toj no yog kev paub txog cov teeb pom kev zoo thiab cov khoom tseem ceeb ntawm cov teeb thiab teeb, yog li kuv yuav tsum nres ntawm no thawj zaug. Cov ntsiab lus yog rau koj siv nkaus xwb, thiab kuv vam tias nws tuaj yeem pab tau rau koj.
