Hauv peb lub chaw kuaj mob, muaj ib lub cuab yeej zoo li lub ntsej muag xiav. Nws yuav tsis zoo li ntau, tab sis nws ua lub luag haujlwm tseem ceeb - nws hu ua ibkev sib koom ua ke.
Xav tias nws yog "kev kuaj kho qhov muag-up" rau txhua daim iav LED peb ua. Nws tsis ntsuas seb daim iav zoo li cas - nws ntsuaslub teeb zoo npaum li cas tiag.
Nws ntsuas li cas?
Thaum peb tso ib lub LED sawb los yog ib daim iav tiav rau hauv qhov sib koom ua ke, nws muab cov ntaub ntawv tseem ceeb hauv qab no rau peb:
- Luminous kev ua tau zoo - yuav ua li cas ci lub teeb tiag tiag
- Correlated Color Temperature (CCT) – txawm tias lub teeb sov, nruab nrab, lossis txias
- Xim Rendering Index (CRI) – yuav ua li cas xim tseeb tshwm nyob rau hauv lub teeb
- Chromaticity coordinates thiab xim purity - txawm tias cov xim yog qhov tseeb lossis hloov
- Luminous kev ua tau zoo (lm / W) - ntau npaum li cas lub teeb tsim ib watt ntawm hluav taws xob
Nws ua haujlwm li cas?
Ib qho kev sib koom ua ke yog ib qho hollow kheej kheej nrog nws cov phab ntsa sab hauv coated nrog cov khoom siv zoo heev diffuse dawb. Thaum lub teeb pom kev nyob rau hauv lub sphere, lub teeb undergoesntau reflections thiab diffuse reflectionshla lub puab nto, nws thiaj li tsim ib tuguniform teeb faibntawm phab ntsa kheej kheej. Los ntawm kev ntsuas lub teeb lub zog ntawm thaj tsam me me ntawm phab ntsa, peb tuaj yeem suav covtag nrho luminous fluxemitted los ntawm qhov chaw.
Hauv cov ntsiab lus yooj yooj yim: txawm tias lub teeb mus rau qhov twg, lub sphere sau tag nrho nws, txawm tias nws tawm, thiab cia peb ntsuas nws kom raug.
Vim li cas qhov kev xeem no tseem ceeb?
Rau LED chav dej iav, lub teeb tsis yog hais txog "tig." Nws yog hais txog qhov tseeb thiab sib xws.
Thaum tus neeg siv khoom siv daim iav rau pleev, chais plaub hau, lossis xaiv cov khaub ncaws, lawv xav tau lub teeb uas qhia cov xim tiag tiag. Yog tias qhov kub thiab txias ntawm cov xim tsis zoo lossis CRI tsawg dhau, qhov lawv pom hauv daim iav yuav tsis zoo li lawv saib sab nraud.
Qhov no txhais li cas rau cov neeg siv khoom?
Txhua batch ntawm peb cov tsom iav LED muaj nws cov ntaub ntawv kho qhov muag pom tseeb hauv kev sib koom ua ke. Lub brightness, xim kub, thiab xim rendering koj tau txais yogtraceable thiab testable- tsis yog "zoo li txoj cai."
Yog tias koj xav paub ntau ntxiv txog peb qhov kev sim kho qhov muag, thov hu rau peb txhua lub sijhawm.
