Saib rau Underwriters Laboratories (UL) ntawv pov thawj.
Daim ntawv lo UL qhia tias LED tau dhau los kuaj kev nyab xeeb, kev kuaj xyuas, thiab kev kuaj xyuas. Txawm li cas los xij, cov khoom lag luam UL cim tsis tau lees tias lub cim yog qhov tseeb. Qee cov leds muaj cov cim tsis tseeb UL lossis tsis phim cov chaw tsim khoom lossis cov khoom lag luam UL tus lej sau npe. Mus saib dawb "UL Online Certification Directory" kom paub meej tias UL cim.
Paub meej txog Kev Tsim Teeb Pom Kev Zoo (DLC) Kev Tsim Nyog rau plaub yam hauv qab no ua rau tsis ua haujlwm ntxov ntawm LED teeb ua haujlwm.
Lub koom haum Northeast Energy Efficiency Partnership, ib pab pawg tsis muaj txiaj ntsig tau tsim nrog lub hom phiaj ntawm kev zam lub teeb pom kev tsis ua haujlwm, yog lub koom haum tom qab DLC txoj haujlwm. Kev lag luam LED qhov muag teev, cov khoom siv rov ua dua tshiab, cov teeb hloov kab, E39 ntsia hlau hauv paus, thiab lwm cov teeb hloov LED tau raug tshuaj xyuas thiab tau lees paub kom ua tau raws li cov qauv kev ua tau zoo. Lawv ua raws li cov qauv siab, siv cov khoom zoo hauv lawv cov kev tsim khoom, thiab muab 5- xyoo lav rau cov khoom LED ua lub cim ntawm lawv qhov zoo tshaj.
Txhawm rau kom paub tseeb tias lub teeb muaj zog, ua raws li cov lus qhia saum toj no. High-quality LEDs yuav txo tau lub sij hawm hloov thiab cov nqi, txias load, thiab txaus ntshai ntawm hluav taws xob poob siab thaum hloov, thiab txuag 50 feem pua rau 90 feem pua ntawm cov teeb pom kev zoo.
Lub LED kav ntev npaum li cas, raws nraim?
Lub neej expectancy nyob rau hauv lub xyoo tej zaum yuav xam tau yooj yim. Tag nrho cov teev hauv ib xyoos yog 2,555 yog tias peb xav tias lub teeb ci LED yog rau 7 teev nyob rau ib hnub nyob rau nruab nrab rau 365 hnub. 9.7 xyoo yuav dhau mus yog tias lub teeb LED kav ntev li 25, 000 teev ua haujlwm raws li tau hais tseg.
Puas yog LEDs poob qee qhov ntawm lawv lub teeb tso zis dhau sijhawm?
Thaum muas ib lub teeb, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov luminous lwj. Nyob rau hauv lawv lub neej, txhua qhov chaw teeb pom kev zoo poob rau hauv lub teeb pom kev zoo. Tab sis tawm ntawm txhua qhov kev xaiv, LEDs muaj lub teeb pom kev zoo tshaj plaws, lossis L70. Es tsis txhob poob tam sim ntawd tom qab ua tiav lawv lub neej xav tau, lub teeb tso zis maj mam dims.
Dab tsi txawv qhov kev ntsuas lub neej rau LED ua haujlwm teeb los ntawm cov khoom siv rau cov teeb pom kev zoo?
Vim muaj qhov sib txawv loj ntawm cov thev naus laus zis ntawm LEDs thiab cov chaw teeb pom kev zoo, qhov ntsuas lub neej ntawm LED yuav tsum suav qhov sib txawv.
Ib qho tseem ceeb coj los ntawm US Department of Energy qhov kev tshuaj xyuas ntawm LED tsis ua hauj lwm yog ua tib zoo saib xyuas streamer thiab L70 thaum yuav cov LEDs es tsis yog qhov nruab nrab thov lub neej.
Raws li peb nyiam hais, peb nyob ntawm no kom teeb pom kev yooj yim dua. Kuv tsis sim siv terminology uas yuav blindside koj. Tab sis vim tias cov kev sib txawv no yog qhov tseem ceeb, cia peb siv sijhawm los piav qhia lawv txhua tus txhais li cas.
