Qhov sib txawv ntawm qhov tsis tshua muaj siab sodium teeb thiab siab siab sodium teeb
1. Tsis tshua muaj siab sodium teeb
Low-pressure sodium teeb yog lub teeb hluav taws xob uas siv hluav taws xob tsawg sodium vapor tawm kom tawm lub teeb. Nws lub khob iav yog coated nrog ib qho infrared reflective zaj duab xis. Nws yog ib qho hluav taws xob lub teeb pom kev zoo nrog lub teeb pom kev tsawg thiab ua haujlwm siab luminous. Lub teeb hluav taws xob qis sodium emits lub teeb daj monochromatic, uas yog siv nyob rau hauv qhov chaw uas tsis muaj qhov yuav tsum tau rau lub teeb xim, tab sis nws" huab permeability" yog qhov zoo heev, tshwj xeeb tshaj yog tsim rau txoj kev loj, txoj kev tsheb khiav, txoj kev hauv nroog, cov voj voog pej xeem, thiab cov teeb pom kev hauv tsev, tuaj yeem ua rau tib neeg pom cov khoom nrog cov xim me me sib txawv kom meej. Low-pressure sodium teeb kuj yog ib yam ntawm high-efficiency teeb uas hloov high-pressure mercury teeb kom txuag hluav taws xob, thiab nws daim ntawv thov chaw kuj nthuav.
Lub teeb uas tsis tshua muaj siab sodium yog ib qho hluav taws xob qis sodium vapor discharge raj. Lub raj sab hauv yog tshuab nrog tshwj xeeb anti-sodium iav. Tom qab ignited, nws muaj peev xwm radiate 5890A thiab 5896A sodium spectrum. Nws tuaj yeem siv los ua tus polarimeter, refractometer, polarimeter thiab lwm yam khoom siv kho qhov muag. Monochromatic lub teeb ci.
2. Kev kub siab sodium teeb
Kev ua haujlwm vapor siab ntawm high-pressure sodium teeb yog ntau dua 0.01 MPa. Lub teeb hluav taws xob sodium siab yog tsim los rau qhov tsis zoo ntawm lub teeb hluav taws xob tsawg sodium xws li muaj zog monochromaticity, tsis zoo xim rendering, thiab lub raj xa dej ntev dhau. Lub teeb hluav taws xob siab siab sodium tau muab faib ua hom zoo tib yam (tus qauv), nws qhov kev ua haujlwm luminous yog 130lm / W, xim rendering Performance index Ra=25; txhim kho hom, nws cov luminous efficiency yog 75lm / W, xim rendering Performance index Ra=60; High xim rendering hom, nws lub luminous efficiency yog 45-60lm / W, thiab xim rendering Performance index Ra=80-85. Dab tsi yog tsim yog lub teeb daj. Lub teeb siab sodium teeb yog tsim los ntawm translucent polycrystalline alumina (PCA) ceramic arc raj, lub teeb sab nrauv, hlau bracket, getter thiab teeb lub hau. Lub arc raj yog lub hauv paus ntsiab lus, muaj mercury, sodium thiab inert gas. Thaum tso tawm, sab hauv sodium vapor siab yog 10-100kPa.
Lub high-pressure sodium teeb emits golden dawb lub teeb thaum siv. Nws muaj qhov zoo ntawm kev ua haujlwm siab luminous, tsawg zog noj, lub neej ntev, muaj zog pos huab nkag thiab tsis muaj kab attraction. Nws yog dav siv nyob rau hauv txoj kev, txoj kev loj, tshav dav hlau, chaw nres tsheb, chaw nres tsheb, chaw nres tsheb, squares, txoj kev sib tshuam, kev lag luam thiab kev lag luam mining, chaw ua si, thaj chaw, thiab cog qoob loo. High-xim-rendering high-pressure sodium teeb yog tsuas yog siv rau teeb pom kev zoo hauv chaw ntau pob, exhibition halls, casinos, department khw thiab tsev so.
