Cov tsis tseem ceeb ntawm LED rooj teeb muaj 11 yam hauv qab no:
1. Xim kub: cov xim xim kub: sov dawb lub teeb (WW) 2700-3200k, ntuj lub teeb (NW) 4000-4500K, zoo dawb lub teeb (PW) 6000-6500K, thiab lwm yam .;
2. Lub zog: Lub zog dav dav ntawm LED qhov muag teev yog qis dua 12W.
3. Voltage thiab tam sim no: Feem ntau siv voltages yog 12v, 110v, 220v, 85v-265v. Tam sim no muaj kev cuam tshuam zoo rau lub teeb attenuation ntawm LED teeb, yog li qhov kev ruaj ntseg ntawm qhov tam sim no tseem ceeb heev. Lub teeb hlaws tam sim no thiab qhov hluav taws xob yuav tsum tsis txhob loj dhau, txwv tsis pub nws yuav cuam tshuam rau lub neej ntawm LED teeb.
4. Luminous efficiency: Tam sim no, lub luminous efficiency ntawm lub teeb hlaws siv Taiwanese chips nyob rau hauv Tuam Tshoj yog nyob ib ncig ntawm 100-130Lm / W.
5. Luminous flux: Lub luminous flux yog tsuas yog txiav txim los ntawm lub luminous efficiency thiab lub hwj chim ntawm lub LED teeb.
6. Illuminance: 250lx-500lx nyob rau hauv qhov chaw ua hauj lwm illuminated los ntawm lub rooj teeb, thiab qhov tsawg kawg nkaus illuminance yuav tsum yog ≥120lx.
7. Luminous decay: Nyob rau hauv cov nqe lus nrov, luminous decay yog ntau npaum li cas lub brightness ntawm lub teeb lub teeb txo tom qab ib tug tej lub sij hawm ntawm kev siv. Qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev lwj ntawm LED teeb yog cua sov dissipation thiab tam sim no. Yog tias qhov tam sim no tsis ruaj khov thiab cov nyhuv tshav kub tsis zoo, lub teeb lwj yuav hnyav heev.
8. Xim txawv: Xim txawv yog qhov tsis sib xws ntawm cov xim kub. Feem ntau, sov dawb lub teeb (2700-3200k) yuav coj cov xim txawv rau hauv kev xav. Lub teeb sov sov yog qhov peb feem ntau hu ua lub teeb daj
9. Xim rendering: Qhov degree ntawm qhov teeb pom kev zoo nthuav tawm xim ntawm cov khoom nws tus kheej hu ua xim rendering, uas yog qib ntawm cov xim fidelity. Lub International Commission on Illumination (CIE) tau teeb tsa cov xim rendering Performance index ntawm lub hnub rau 100. Ib lub teeb pom kev zoo nrog lub siab xim rendering Performance index (Ra) yuav tsum tau siv los qhia qhov tseeb xim ntawm cov khoom. Tus nqi yog ze rau 100 thiab cov xim rendering yog qhov zoo tshaj plaws.
10. Glare: Muaj cov khoom uas muaj qhov ci ntsa iab heev lossis muaj zog ci ntsa iab nyob rau hauv qhov kev pom, uas tuaj yeem ua rau pom qhov tsis xis nyob hu ua glare. Glare yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm lub teeb pom kev zoo.
11. Kev pab lub neej: LED teeb feem ntau muaj lub neej kev pab ntau tshaj 50,000 teev. Yog vim li cas vim li cas LED yog qhov ruaj khov yog tias nws yuav tsis ua teeb meem ntawm filament fusing. LED yuav tsis tso tseg kev ua haujlwm ncaj qha, tab sis nws yuav maj mam degrade dhau sijhawm. Thermal zog yog lub ntsiab yog vim li cas LEDs tsis ua hauj lwm. Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm LEDs, nws yog ib qho tsim nyog los txo lossis dissipate lub thermal zog tsim los ntawm LED chips.
