Nrog rau kev vam meej thiab kev loj hlob ntawm tib neeg, lub zog thiab ib puag ncig teeb meem tau nce los ua qhov tseem ceeb ntawm lub ntiaj teb.Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig tau nce zuj zus los ua lub zog tseem ceeb ntawm kev vam meej hauv zej zog.Nyob rau hauv tib neeg lub neej txhua hnub, qhov kev thov rau lub teeb pom kev zoo muaj feem ntau ntawm tag nrho cov kev siv hluav taws xob, tab sis cov teeb pom kev zoo uas twb muaj lawm muaj qhov tsis xws li kev siv hluav taws xob loj, kev pab cuam lub neej luv luv, kev hloov pauv tsis zoo thiab ib puag ncig muaj kuab paug, uas tsis yog nyob rau hauv txoj kab nrog lub hom phiaj ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig hauv lub neej niaj hnub no, Yog li ntawd, yuav tsum muaj lub teeb pom kev tshiab uas ua tau raws li qhov xav tau ntawm kev txhim kho hauv zej zog los hloov cov teeb pom kev zoo ib txwm muaj.

Los ntawm kev siv zog txuas ntxiv ntawm cov kws tshawb fawb, hom teeb pom kev ntsuab nrog lub neej ua haujlwm ntev, kev hloov pauv siab thiab kev ua qias tuaj ib puag ncig, uas yog semiconductor dawb lub teeb emitting diode (WLED), tau npaj.Piv nrog rau cov teeb pom kev zoo ib txwm muaj, WLED muaj qhov zoo ntawm kev ua haujlwm siab, tsis muaj mercury muaj kuab paug, qis carbon emission, lub neej ua haujlwm ntev, ntim me me thiab txuag hluav taws xob, Qhov no ua rau nws siv dav hauv kev thauj mus los, teeb pom kev zoo, khoom siv kho mob thiab khoom siv hluav taws xob.

Tib lub sijhawm,LEDtau raug lees paub tias yog lub teeb pom kev zoo tshaj plaws nyob rau hauv lub xyoo pua 21st.Nyob rau hauv tib lub teeb pom kev zoo, lub zog noj ntawm WLED yog sib npaug rau 50% ntawm cov teeb fluorescent thiab 20% ntawm cov teeb ci.Tam sim no, lub ntiaj teb ib txwm siv hluav taws xob siv hluav taws xob suav txog li 13% ntawm lub ntiaj teb kev siv hluav taws xob tag nrho.Yog tias WLED tau siv los hloov lub ntiaj teb ib txwm teeb pom kev zoo, kev siv hluav taws xob yuav raug txo los ntawm ib nrab, nrog rau kev txuag hluav taws xob zoo kawg thiab cov txiaj ntsig kev lag luam.

Tam sim no, lub teeb dawb emitting diode (WLED), lub npe hu ua cov khoom siv hluav taws xob thib plaub, tau nyiam ntau yam vim nws qhov kev ua tau zoo heev.Tib neeg tau maj mam ntxiv dag zog rau kev tshawb fawb ntawm LED dawb, thiab nws cov cuab yeej siv tau dav siv hauv ntau qhov chaw xws li zaub thiab teeb pom kev zoo.

Xyoo 1993, Gan xiav lub teeb emitting diode (LED) thev naus laus zis tau ua tiav thawj zaug, uas txhawb kev txhim kho ntawm LED.Thaum xub thawj, cov kws tshawb fawb siv Gan ua lub teeb xiav xiav thiab pom tau hais tias lub teeb dawb emission ntawm ib qho coj los ntawm kev siv phosphor hloov dua siab tshiab, uas ua kom lub zog ntawm LED nkag mus rau hauv lub teeb pom kev zoo.

Daim ntawv thov loj tshaj plaws ntawm WLED yog nyob rau hauv kev teeb pom kev hauv tsev, tab sis raws li kev tshawb fawb tam sim no, WLED tseem muaj teeb meem loj.Txhawm rau ua kom WLED nkag mus rau peb lub neej sai li sai tau, peb yuav tsum tau txhim kho thiab txhim kho nws cov luminous efficiency, xim rendering thiab kev pab cuam lub neej.Txawm hais tias tam sim no lub teeb ci LED tsis tuaj yeem hloov pauv cov teeb pom kev zoo ib txwm siv los ntawm tib neeg, nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, LED teeb yuav dhau los ua neeg nyiam.
