Raws li ntau phau ntawv qhia kev yuav khoom hauv kev lag luam, ntawm no yog cov yam tseem ceeb.
1. Qhov ntev ntawm nthwv dej
-
Lub cuab yeej yuav tsum hais meej meej txog cov wavelengths uas tawm hauv nanometers (nm).
-
Rau kev kho mob ntawm daim tawv nqaij/qhov chaw: ~ 630‑660 nm.
-
Rau cov nqaij ntshiv tob dua, cov pob qij txha, cov leeg nqaij: ~ 810‑850 nm (ze-infrared) yog qhov zoo tagnrho.
-
Cov khoom siv uas sib xyaw ua ke ob qho tib si muaj ntau yam siv tau.
2. Kev ci ntsa iab / Lub zog tso zis / Kev pab them nqi
-
Lub zog ua haujlwm zoo (irradiance) tseem ceeb: nws txiav txim siab tias lub zog teeb ci ntau npaum li cas tiag tiag ncav cuag koj cov ntaub so ntswg.
-
Qhov "cheeb tsam kho mob" (qhov loj ntawm lub cuab yeej) yuav tsum phim qhov koj xav npog ntawm koj lub cev (lub ntsej muag xwb, pob qij txha, tag nrho lub cev).
-
Nrhiav cov khoom siv uas qhia lawv cov zis ntawm qhov deb ntawm tus neeg siv. Qee cov pheej yig dua muab cov lej spec ntawm qhov chaw LED (uas ua rau yuam kev).
3. Kev Nyab Xeeb, Daim Ntawv Pov Thawj & Zoo
-
Tshawb xyuas cov ntawv pov thawj kev nyab xeeb: piv txwv li, FDA kev tso cai / kev sau npe, CE cim, UL / ETL thiab lwm yam.
-
Kev tsim kho zoo: lub kaw lus txias (rau cov khoom siv hluav taws xob siab), kev ruaj khov, kev tshuaj xyuas zoo los ntawm cov neeg siv.
-
Tshawb xyuas seb puas muaj EMF (electromagnetic field) tso zis tsawg, tsawg kawg nkaus flicker tshwj xeeb tshaj yog tias koj yuav nyob ze rau nws.
4. Hom Ntawv thiab Kev Siv Tau ntawm Cov Khoom Siv
-
Txiav txim siab hom ntawv: tus pas nrig tes (hauv zos), lub npog ntsej muag, vaj huam sib luag (cheeb tsam loj dua), txaj pw tag nrho lub cev. Koj qhov kev xaiv nyob ntawm seb koj kho dab tsi.
-
Yooj yim siv: teeb tsa lub sijhawm, kho qhov deb/lub kaum sab xis tau, yooj yim nqa mus los yog tias xav tau.
-
Kev lav thiab kev txhawb nqa hom lag luam: Cov hom lag luam zoo txhawb nqa lawv cov khoom siv.
5. Nqe piv rau Tus Nqi
-
Tsis txhob xav tias qhov kim tshaj plaws yeej ib txwm txhais tau tias zoo tshaj plaws rau koj lub hom phiaj. Tab sis cov khoom pheej yig heev yuav cuam tshuam rau cov lus qhia tshwj xeeb (qhov tseeb ntawm lub wavelength, irradiance) thiab tsis muaj txiaj ntsig ntau.
-
Ua kom lub cuab yeej sib haum rau koj lub hom phiaj tseem ceeb (tsuas yog daim tawv nqaij piv rau cov nqaij sib sib zog nqus piv rau tag nrho lub cev) yog li koj yuav tsis yuav ntau dhau.
Yuav ua li cas xaiv raws likoj lub hom phiaj
-
Lub hom phiaj: kev kho kom tawv nqaij zoo nkauj / lub ntsej muag xwb→ tsom mus rau 630‑660 nm cov khoom siv, kev npog me dua, hom ntawv yooj yim (wand/mask).
-
Lub Hom Phiaj: kev rov zoo cov leeg nqaij / cov pob qij txha / mob / cov nqaij tob dua→ xyuas kom meej tias lub cuab yeej muaj ~ 810‑850 nm lossis muaj kev nkag mus tob zoo, vaj huam sib luag loj dua lossis hom ntawv qhwv tshwj xeeb.
-
Lub Hom Phiaj: kev noj qab haus huv tag nrho lub cev / npog thaj chaw tseem ceeb→ vaj huam sib luag loj / puv lub cev txaj hom, irradiance siab dua, ob lub wavelengths (liab + NIR) rau qhov zoo tshaj plaws.
-
Kev txwv ntawm nyiaj txiag thiab qhov chaw→ cov khoom siv me me xwb tab sis xyuas cov lus qhia kom zoo zoo (wavelength + irradiance) kom koj thiaj li tsis ua haujlwm zoo.
-
Kev ua neej nyob / kev siv tau yooj yim→ yog tias koj yuav siv nws ntau zaus, xaiv ib yam dab tsi uas koj yuavtxaus siab rausiv (hom ntawv yooj yim, teeb tsa yooj yim, kev txhawb nqa zoo) vim tias kev sib xws tseem ceeb rau cov txiaj ntsig.
