Qhov tseem ceeb teeb pom kev zoo Terminology: Phau Ntawv Qhia
Kev lag luam teeb pom kev zoo siv cov lus tshwj xeeb uas tuaj yeem nyuaj rau cov neeg siv khoom thiab cov kws tshaj lij. Phau ntawv qhia no muab cov lus piav qhia meej txog cov ntsiab lus teeb pom kev zoo, pab koj txiav txim siab seb koj tab tom xaiv teeb pom kev zoo hauv tsev lossis npaj kev lag luam teeb tsa.
Hluav taws xob Fundamentals
Volts (V)
Voltage sawv cev rau cov hluav taws xob muaj peev xwm sib txawv uas thawb tam sim no los ntawm ib lub voj voog. Xav tias nws yog dej siab hauv cov kav dej - siab dua (voltage) ua rau dej (tam sim no) ntws ntau zog. Hauv North America, tus qauv hluav taws xob hauv tsev yog 120V, thaum ntau lub tebchaws siv 220-240V systems. Nkag siab txog koj qhov voltage hauv zos yog qhov tseem ceeb thaum xaiv cov teeb pom kev zoo kom ntseeg tau tias muaj kev sib raug zoo thiab kev nyab xeeb.
Watts (W)
Watts ntsuas hluav taws xob siv hluav taws xob - tus nqi ntawm lub cuab yeej siv lub zog. Keeb kwm, cov neeg siv khoom koom nrog ntau dua wattage nrog lub teeb pom kev zoo, tab sis qhov kev sib raug zoo no tsis siv rau niaj hnub LED thev naus laus zis. Niaj hnub no, watts feem ntau qhia cov nqi khiav lag luam ntau dua li cov zis tawm. Piv txwv li, ib txwm siv 60-watt incandescent teeb thiab 10-watt LED tuaj yeem tsim qhov ci zoo sib xws, tab sis LED siv kwv yees li 80% tsawg zog.
Lub Teeb Zoo Metrics
Lumens (lm)
Lumens ntsuas tag nrho cov teeb pom kev tawm los ntawm qhov chaw - qhov tseeb ntsuas qhov ci. Tsis zoo li watts, uas ntsuas lub zog noj, lumens ncaj qha qhia lub teeb tso zis. Qhov siab dua qhov kev ntsuas lumen, qhov ci ntsa iab tshwm rau tib neeg lub qhov muag. Raws li cov ntsiab lus siv, ib txwm muaj 60-watt incandescent noob tsim kwv yees li 800 lumens, thaum lub teeb 100-watt tsim ib ncig ntawm 1600 lumens.
Luminous Efficiency (lm/W)
Qhov kev ntsuas tseem ceeb no sawv cev rau kev ua tau zoo - yuav ua li cas lub teeb pom kev zoo hloov hluav taws xob rau hauv lub teeb pom kev. Muab xam raws li lumens ib watt, cov nqi siab dua qhia tau tias kev ua haujlwm zoo dua. Niaj hnub nimno LEDs feem ntau ua tiav 80-150 lm / W, thaum cov teeb pom kev zoo tsuas yog 10-17 lm / W. Qhov kev ntsuas no pab cov neeg siv khoom sib piv lub zog ua haujlwm ntawm cov teeb pom kev sib txawv.
Xim kub (CCT)
Ntsuas hauv Kelvins (K), Correlated Color Temperature piav qhia qhov pom qhov sov sov lossis qhov txias ntawm lub teeb dawb. Lub scale ranges los ntawm:
Dawb (2000K-3000K): Tsim kom muaj qhov chaw zoo nkauj, zoo ib yam li hnub poob lossis teeb pom kev zoo
Ntuj Dawb (3500K-4500K): Muab nruab nrab, sib npaug illumination zoo tagnrho rau cov chaw ua haujlwm
Txias Dawb (5000K-6500K): Muab lub teeb ci ntsa iab, ua kom muaj zog piv rau nruab hnub
Lower Kelvin qhov tseem ceeb ua kom sov (daj) lub teeb, thaum cov nqi siab dua tsim kom txias (blue) lub teeb.
Xim Rendering Index (CRI)
CRI ntsuas lub teeb lub peev xwm los nthuav tawm cov khoom 'xim tiag tiag piv rau lub hnub ci ntuj. Rated ntawm qhov ntsuas ntawm 0-100, siab dua CRI qhov tseem ceeb qhia qhov tseeb xim zoo dua. Rau feem ntau daim ntawv thov, nrhiav CRI 80+; rau cov khw muag khoom, kos duab, lossis chaw kho mob, CRI 90+ muab kev ntxub ntxaug xim zoo tshaj.
Khoom Specifications
Teeb Fittings / Bases
Qhov haum (los yog hauv paus) tsim lub cev sib cuam tshuam ntawm lub teeb thiab nws lub qhov (socket), kom ntseeg tau cov hluav taws xob sib txuas thiab kev txhawb nqa txhua yam. Cov hom muaj xws li:
Pob zeb (B22): Push-thiab-twist kev twb kev txuas uas muaj nyob rau hauv Commonwealth lub teb chaws
Edison Ntsia Hlau (E26 / E27): Txheem ntsia hlau- puag rau North America (E26) thiab Europe (E27)
GU10: Twist-lock bi-pin puag rau kev taw qhia teeb pom kev zoo
G13: Ob -pin puag tus qauv rau T8 / T12 fluorescent raj
G5: Miniature ob -pin puag rau T5 fluorescent raj
Nco ntsoov xyuas fixture compatibility ua ntej yuav hloov cov teeb.
Lifespan thiab Kho
Rated Lub Sij Hawm Sij Hawm
Cov neeg tsim khoom suav teeb lub neej sib txawv ntawm cov thev naus laus zis:
Incandescent: Txiav txim siab thaum 50% ntawm cov qauv kuaj tsis ua tiav (B50 txoj kev)
LED: Raws li kev saib xyuas lumen - feem ntau yog qhov taw tes (L70) thaum tso zis poob rau 70% ntawm thawj lumens
Thaum cov khoom siv LED tuaj yeem thov 25,000-50,000 xuab moos lifespan, lub neej ntev nyob ntawm kev ua haujlwm, tshwj xeeb tshaj yog kev tswj xyuas thermal.
Lumen Maintenance
Qhov kev qhia tshwj xeeb no qhia tau hais tias lub teeb ci zoo li cas tswj nws qhov ci ci thaum pib. Qhia tawm raws li feem pua ntawm cov lumens qub tom qab lub sijhawm tshwj xeeb (xws li L90 @ 10,000 teev), nws pab kwv yees thaum lub teeb pom kev zoo yuav xav tau kev hloov pauv vim qhov ci tsis txaus es tsis ua tiav.
Advanced Technical Concepts
Lub zog Factor (PF)
Lub zog hluav taws xob ntsuas qhov hluav taws xob hloov pauv tau zoo npaum li cas rau kev ua haujlwm muaj txiaj ntsig, xws li 0 txog 1. Cov txiaj ntsig PF siab dua (Ntau dua lossis sib npaug ntawm 0.9) qhia tias kev ua haujlwm zoo dua thiab txo qis ntawm cov tshuab hluav taws xob. Kev teeb tsa kev lag luam feem ntau tau txais txiaj ntsig los ntawm siab - zog- teeb pom kev zoo kom txo qis hluav taws xob pov tseg.
IP (Ingress Protection) Kev Ntsuas
Tus IP code faib cov qib kev tiv thaiv ib puag ncig siv hom IPXY:
Thawj tus lej (X)Kev tiv thaiv khoom particle (0-6)
Tus lej thib ob (Y)Kev tiv thaiv dej noo (0-8)
Piv txwv li, IP65 qhia cov plua plav- nruj kev tsim kho nrog kev tiv thaiv cov dav hlau dej, ua rau nws tsim nyog rau kev siv sab nraum zoov lossis kev lag luam.
Beam Angle
Tshwj xeeb yog cuam tshuam rau kev taw qhia teeb pom kev zoo, beam kaum sab xis txiav txim siab lub teeb kis. Nqaim kab teeb (tsawg dua lossis sib npaug li 30 degree) tsim lub teeb pom kev zoo, thaum kab teeb dav (Ntau dua lossis sib npaug li 60 degree) muab kev pom dav dav. Xav txog ob lub kaum sab xis thiab daim ntawv thov thaum xaiv cov khoom siv rau cov haujlwm tshwj xeeb.
Kev xav txog kev siv
Thaum npaj cov teeb pom kev zoo:
Ua ntej lumens tshaj watts rau kev ntsuas qhov ci
Sib phim xim kub rau daim ntawv thov
Tshawb xyuas lub cev thiab hluav taws xob sib raug zoo
Xav txog lub sijhawm ntev - ntsuas kev ua tau zoo tshaj li tus nqi pib
Ntsuas ib puag ncig tej yam kev mob rau qhov tsim nyog tus IP ntsuam xyuas
Lub hauv paus ntsiab lus no ua rau muaj kev sib txuas lus zoo dua nrog cov kws tshaj lij teeb pom kev zoo thiab ua kom paub meej txog kev txiav txim siab- ua rau ob qho tib si nyob thiab cov haujlwm lag luam. Raws li lub teeb pom kev siv thev naus laus zis txuas ntxiv mus, kev nkag siab cov ntsiab lus tseem ceeb no yuav pab koj taug qab cov kev txhim kho tshiab thiab ua kom zoo dua koj cov kev nqis peev teeb pom kev zoo.
