Yuav ua li cas los ntsuas lub lumen txij nkawm ntawm LED cov khoom yog ib qho tseem ceeb parameter los txiav txim qhov zoo ntawm cov khoom, thiab kuj yog ib qho tseem ceeb qhia kom paub qhov txawv qhov zoo ntawm lub teeb. Qhov tseem ceeb ntawm LM80 rau cov khoom siv LED yog qhov tseeb ntawm tus kheej. Yog li, yuav ua li cas txiav txim seb LM-80 tsab ntawv ceeb toom puas tsim nyog lossis tsis? Hauv qhov no, Muaj ob peb lub ntsiab lus uas tsim nyog rau kev mloog: 1, Qhov feem pua ntawm cov luminous attenuation thiab attenuation nkhaus ntawm cov khoom kuaj. 2, Cov xim drift ntawm cov khoom kuaj, uas yog, xim txawv ntawm 6000 teev thiab 0 teev.
Qhov thib ob, nws tseem tsim nyog sau cia seb LM -80 cov ntawv ceeb toom muaj kev tso cai, txawm tias nws ua tau raws li tus qauv ntawm cov kev cai xeem, seb tus qauv kom muaj nuj nqis raws li qhov yuav tsum tau ua ntawm cov khoom tiav cov khoom siv hluav taws xob ua haujlwm tau ntawv pov thawj, seb cov xim txawv raws li tus qauv. cov kev xav tau, seb qhov feem pua ntawm attenuation thiab nws lub neej kwv yees tuaj yeem ua tau raws li qhov yuav tsum tau ua.
