Tus lej kelvin qis dua txhais tau tias tus lub teeb tshwm ntau daj; mas kelvin cov zauv txhais tus lub teeb yog dawb los yog xiav. CFLs thiab LEDs yog tsim kom haum rau cov xim ntawm incandescent qhov muag teev ntawm 2700-3000K. Yog tias koj xav tau whiter lub teeb , nrhiav qhov muag teev cim 3500-4100K.

Ua kom pom qhov no, cov lej LED txhais li cas?

Tias txhais tau tias qhov no yog ib LED Chip (duab) mounted ncaj qha mus rau ib lub teeb sawb, tsis siv xov hlau. Qhov thev naus laus zis thev naus laus zis no yog qhov tseeb ua dab tsi LED Lub teeb ci tau. Cov zauv tom qab SMD tsuas yog xa mus rau qhov loj ntawm lub cev LED Chip.

Ntxiv mus, LED teeb pom kev zoo li cas? LEDs yog "directional" lub teeb cov peev txheej, uas txhais tau tias lawv tso tawm lub teeb nyob rau hauv cov lus qhia tshwj xeeb, tsis zoo li cov roj teeb thiab CFL, uas tso tawm lub teeb thiab cua sov hauv txhua qhov kev taw qhia. Txhais tau tias LEDs muaj peev xwm siv tau lub teeb thiab lub zog muaj txiaj ntsig ntau hauv kev siv ntau yam. Feem ntau LED cov xim suav nrog amber, liab, ntsuab, thiab xiav.

Kuj Paub, dab tsi yog hauv lub teeb LED?

LED qhov muag teev siv cov khoom siv semiconductor uas tawm lub teeb pom kev thaum muaj hluav taws xob dhau los ntawm nws. Cov khoom ntawd yog hu ua elecroluminescence. Compact fluorescent s, feem ntau lwm txoj rau incandescent qhov muag teev, siv hluav taws xob rau excite mercury roj kom txog rau thaum nws tawm ultraviolet (UV) lub teeb.

Kuv yuav xaiv lub teeb ci LED li cas?

Yuav xaiv lub LED li cas

  1. Ua ib daim ntawv.
  2. Koj xav tau xim dab tsi?
  3. Paub koj watts los ntawm koj lub lumens (brightness lossis lub teeb tso zis)
  4. Suav koj cov nyiaj txiag thiab kev txuag ib puag ncig.
  5. Pib nrog ib lub teeb.
  6. Ntsuam xyuas koj qhov muag teev.
  7. Hloov cov teeb uas koj siv tshaj plaws kom txuag tau nyiaj ntau.
  8. Xav txog qhov ntev ntawm lub teeb.
