Qhov twg yog tus nqi ntawm peb-pov thawj teeb thiab teeb ci feem ntau kim?
Vim li cas tus nqi ntawm LED peb-pov thawj teeb thiaj li kim? Qhov no yog ib lo lus nug uas ntau tus neeg siv khoom siv teeb pom kev zoo LED xav paub. Raws li cov teeb ci incandescent maj mam thim tawm ntawm kev ua lag luam, LED teeb ceev ceev tuav lub lag luam teeb pom kev zoo vim lawv qhov kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob; lawv kuj poob feem ntau ntawm kev ua lag luam vim lawv cov nqi siab. Tam sim no, kev lag luam sib faib ntawm LED teeb yog li ib nrab, tab sis nws tsis tuaj yeem tawg. Txawm hais tias muaj kev sib tw rau lub teeb xws li lub teeb txuag hluav taws xob, qhov laj thawj tseem ceeb yog vim li cas tus nqi siab dhau lawm.
Vim li cas tus nqi ntawm LED teeb thiaj li siab? Vim nws tus nqi siab piv, tshwj xeeb tshaj yog rau domestic. Peb lub tuam txhab teeb pom kev zoo qhia tau hais tias LEDs kim vim peb yam:
Ua ntej tshaj plaws, kev lag luam LED hauv tsev tsis muaj nws tus kheej cov txuj ci tseem ceeb. Ntau lub high-end LED thev naus laus zis yog nyob rau hauv txhais tes ntawm cov kws tshawb fawb tshawb fawb hauv European thiab Asmeskas lub teb chaws. Yog li ntawd, cov khoom siv hauv tsev LED tsuas yog tuav cov nyiaj tau los hauv kev tsim khoom. Vim yog kev txhim kho tas mus li thiab kev txhim kho ntawm LED chips, nws ntau daim ntawv thov yuav txo tus nqi tag nrho ntawm LED khoom. Txawm li cas los xij, tam sim no, kuv lub teb chaws LED chips feem ntau yog los ntawm txawv teb chaws, yog li tus nqi ntawm kev tsim kho yog kim heev.
Qhov thib ob, LED cov khoom yog qhov nyuaj rau dissipate tshav kub. Vim tias qhov tshwj xeeb no, thaum cov tuam txhab tsim cov khoom lag luam LED, lawv feem ntau siv nyiaj ntau ntawm cov khoom siv hluav taws xob. Yog li ntawd, txhawm rau txo tus nqi ntawm cov khoom siv LED, peb tuaj yeem pib los ntawm kev txo tus nqi ntawm cov cua sov dissipation.
Txij li thaum lub zog hluav taws xob yog qhov txuas tsis muaj zog ntawm cov khoom siv LED, nws suav txog 20 feem pua ntawm tag nrho cov nqi ntawm cov khoom siv LED. Yog li ntawd, yog tias cov tuam ntxhab nce kev siv cov raj fais fab rau LEDs
