Dab tsi ua rau koj ruaj ntseg thaum koj tawm hauv hmo ntuj thiab qhov chaw tsaus, lub teeb ncej. Qhov ntawd yog qhov tseem ceeb ntawm cov no hauv peb lub neej. Cov teeb ncej no tsis yog ua kom peb muaj kev nyab xeeb ntawm kev mob hmo ntuj, tab sis kuj txuag lub zog los ntawm kev ua kom muaj zog heev.
Muaj nyob rau hauv txawv wattages, cov ncej teeb muaj lub neej ntev dua li hlau halide los yog high-pressure sodium teeb. Kuj tseem siv rau chaw ua si, cov teeb vaj tsev no tuaj nyob rau hauv ntau txoj kev xaiv mounting. Muaj cov mounts sib txawv, cov teeb no ua haujlwm sib txawv.
Piv txwv li, lub teeb ncej saum toj kawg nkaus yog siv nyob rau hauv qhov chaw, txoj kev thiab txoj kev taug kev, thaum lub teeb khau khau muaj zog yuav siv tau rau ntawm txoj kev thiab txoj kev.
Dab tsi yog qhov zoo ntawm kev siv ncej teeb
Dusk mus rau kaj ntug teeb: Nrog kev pab los ntawm ib tug photocell, cov teeb yuav cia li hloov mus rau los yog tawm los ntawm kev kuaj pom lub xub ntiag ntawm lub teeb. Qhov ntawd txhais tau hais tias lub teeb, yam tsis muaj kev cuam tshuam hauv phau ntawv yuav hloov thaum tsaus ntuj thiab yuav hloov tawm thaum hnub tuaj.
Kuj hu ua CdS hlwb (Cadmium-Sulfide), lub teeb-dependent resistors (LDR), thiab photoresistors, cov no feem ntau yog cov resistors. Tus resistor hloov tus nqi nyob ntawm seb lub teeb poob mus rau nws qhov chaw.
Kev siv hluav taws xob siab: Cov teeb ncej no npog 95 feem pua ntawm cov hluav taws xob siv rau hauv lub teeb yog li tsuas yog 5 feem pua ntawm cov khoom seem uas tau nkim thaum tshav kub. Qhov no yog qhov tsis sib xws rau cov hlau halide fixtures uas ironically hloov tsuas yog 5 feem pua thiab 95 feem pua tau nkim thaum tshav kub.
Qhov no kuj yog qhov zoo rau ib puag ncig vim tias ib qho no tsis tsim kom muaj cua sov ntau, qhov thib ob vim tias cov LED ncej teeb xav tau lub zog tsawg dua ntawm daim phiaj yog li txo cov fossil-grid raws CO2 tiam.
sab nraum zoov coj ncej teeb
Lub neej ua haujlwm ntev dua: Cov teeb ncej no tau sim ua kom khiav tau 50,000 teev. Qhov ntawd txhais ua 5.7 xyoo ntawm kev thaj yeeb ntawm tus ncej teeb pom kev zoo. Qhov ntawd yog txawm tias koj siv cov teeb ncej no 24 teev ntawm ib hnub.
High colour rendering index: Xim rendering Performance index yog qhov ntsuas ntawm qhov yooj yim npaum li cas lub teeb nyob rau hauv rendering xim, khaws ib qho zoo tagnrho lub teeb qhov chaw xws li nruab hnub nrig li yardstick. Qhov ntawd txhais tau hais tias qhov siab dua CRI ntawm lub teeb, qhov zoo dua yuav yog xim zoo.
CRI ntawm LED ncej teeb yog ntau tshaj 80 uas hloov mus rau hauv 80 feem pua qhov tseeb thaum muab cov xim sib piv rau nruab hnub.
Ntau qhov kev xaiv mounting: Cov teeb khau khau no tuaj yeem muaj ntau yam kev xaiv mounting txhua tus nrog nws tus kheej cov yam ntxwv.
Direct mount: Lub mount no slips ncaj qha rau hauv lub teeb ncaj nraim thiab tsis muaj kev hloov pauv dab tsi.
Slip-fitter / Adjustable / Yoke mount: Tag nrho peb ntawm cov kev xaiv mounting no muaj kev hloov kho ntawm lub kaum sab xis ntawm 45 lossis 90 degrees.
Universal mount: Qhov mount no tuaj yeem ua rau txhua tus ncej thiab tuaj yeem hloov kho ntawm txhua lub kaum ntse ntse. Qhov no yog vim li cas nws yog qhov feem ntau pom mount.
