LED Cheebtsam Hoobkas kuaj hom:
Txhawm rau kom lub teeb ci LED ua haujlwm ntawm qhov kub ntawm Ta (ambinility kub) =Tj (Tsuas Kub Kub) =25 degree , lub teeb LED tsis muaj cua sov dab tsi tsis muaj lub dab dej kub thiab yog lub zog rau lub neej. xeem. Yog li ntawd, nws yog feem ntau pom nyob rau hauv specification. Qhov kub ntawm cov ntaub ntawv ua haujlwm yog Tj=25 degree .
LED teeb pom kev Hoobkas kuaj txoj kev:
The LED high bay lamps are finished products, and the life test is performed using a constant voltage/constant current method. However, the LED lamps include a power supply/shade/heat sink, and the LED high bay is composed of a plurality of LED elements, so the actual The operating temperature of the LED element is higher than the experimental ambient temperature Ta=25° C. (Tj>Tau).
Lub neej ntawm LED yog inversely proportional rau nws siv kub. Yog li ntawd, yog tias LED teeb lub Hoobkas ncaj qha siv lub neej ntawm cov khoom siv LED raws li qhov tshwj xeeb, qhov sib txawv ntawm qhov tshwj xeeb thiab kev siv tiag tiag ntawm LED teeb lub Hoobkas yuav tshwm sim.
Raws li qhov no, Lub Hnub Qub Zog (ENERGY STAR) tau tshaj tawm los ntawm Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Lub Zog (DOE) tau tshaj tawm txoj kev kuaj xyuas LED teeb pom kev zoo-xeev teeb pom kev zoo, thiab nws cov ntsiab lus tau hais tias nws yuav tau txais nws cov teeb pom kev zoo-xeev LED luminaires. Daim ntawv pov thawj yuav tsum tau nrog tsib yam khoom:
1. Daim ntawv qhia txog kev sim duab thaij duab ua raws li IESNA LM-79 txoj kev sim
2. Kev sib koom ua ke cov ntaub ntawv pov thawj cov khoom pov thawj raws li IESNA LM-79 txoj kev sim
3, Lumen txij nkawm tus nqi:
Kev Xaiv Ib: LED Component Performance
. LED Cheebtsam kuaj daim ntawv qhia ua raws li IESNA LM-80 txoj kev sim
. Muab ISTMT (LED tivthaiv hauv qhov ntsuas kub ntsuas) qhia txog cov teeb ci LED
Kev xaiv 2: LED teeb ua haujlwm
. 6,000 teev xeem ntawv qhia ua raws li IESNA LM-79 txoj kev sim.
4, khoom siv hluav taws xob
Muab TMPPS (thawj lub zog ntsuas qhov ntsuas kub) cov ntawv ceeb toom rau LED teeb.
5, warranty
Hauv kev xaiv 1 ntawm lumen txij nkawm tus nqi, ob qhov kev sim cov ntaub ntawv yuav tsum tau. Lub hom phiaj yog los laij lub neej ntawm LED teeb siv LM-80 qhov ntsuas kub ntsuas ntawm cov khoom siv LED, kom qhov ntsuas kub ntawm cov khoom thiab lub teeb tuaj yeem daws tau. Teeb meem lub neej.
