Tshaj li Amber Glow: Nkag siab lubDrawbacks ntawm Blue Light Blocking LED Noob
Lub teeb xiav thaiv cov qij LED thiab cov hlab ntsha tau tshwm sim hauv qhov chaw, ua lag luam raws li cov cuab yeej tseem ceeb rau kev tawm tsam cov qhov muag digital thiab tiv thaiv kev pw tsaug zog. Thaum lawv pom tau hais tias txo qis qhov tshwj xeeb siab -lub zog xiav lub zog (feem ntau nyob ib puag ncig 450-460nm) piv rau cov qauv LEDs, lawv txoj kev saws me nyuam tsis yog yam tsis muaj kev lag luam tseem ceeb thiab muaj peev xwm ua rau muaj teeb meem. Nkag siab txog qhov tsis zoo no yog qhov tseem ceeb rau kev txiav txim siab teeb pom kev zoo.
1. Kev cuam tshuam xim Rendering thiab Visual Distortion:
* Qhov teeb meem tseem ceeb:Lub teeb dawb tseeb encompasses tag nrho cov pom spectrum. Tseem ceeb txo lub teeb xiav inherently distorts xim kev nkag siab. Qhov no yog quantified los ntawmXim Rendering Index (CRI). Thaum cov qauv LEDs feem ntau ua tiav CRIs saum toj no 80 (90+ yog qhov zoo heev), lub teeb xiav xiav thaiv tuaj yeem thawb CRI mus rau hauv 70s lossis qis dua.
* Tiag -Kev cuam tshuam ntiaj teb:Cov xim hauv qab no feem ntau tshwm sim:
* Ntxuav Tawm & Yellowish / Amber:Cov txiaj ntsig pom zoo tshaj plaws yog qhov sov sov, qee zaum txawv xim daj, amber, lossis txawm peachy cam khwb cia. Cov xim dawb zoo li dingy, tsis nkig.
* Blues thiab Purples tsis raug:Cov xim no raug kev txom nyem tshaj plaws, zoo li muted, av nkos, lossis greyish. Qhov txawv ntawm qhov sib sib zog nqus xiav, ntshav, thiab dub tuaj yeem nyuaj.
* Altered Greens thiab Reds:Thaum cov tones warmer yuav zoo li txhim kho, tag nrho cov xim sib npaug yog skewed. Qhov no yog teeb meem rau cov haujlwm uas yuav tsum tau uaqhov tseeb xim kev ntxub ntxaug: nraaj tsim, kos duab, yees duab, xaiv khaub ncaws / pleev, ua noj (kev txiav txim rau cov nqaij ua tiav, zaub freshness), los yog tej yam yooj yim xws li nyeem daim ntawv qhia los yog sib txawv xov.
* Ambiance:Qhov sov so tsis zoo tuaj yeem tsim qhov tsaus ntuj, tsaus muag, lossis "sepia-toned" huab cua uas ntau tus neeg pom qhov tsis txaus siab lossis ntxhov siab rau thaj chaw nyob nruab hnub.
2. Txo lub teeb tso zis thiab ua haujlwm tau zoo:
* Physics:Thaiv lossis hloov lub teeb xiav (uas yog lub zog muaj zog) mus ntev dua, tsis muaj zog wavelengths (xws li liab lossis amber) ua rau poob ntawm tag nrho cov luminous flux. Tib lub zog hluav taws xob tawm tswv yim tsim kom pom tsawg dua lumens.
* Tswv yim:
* Dimmer Spaces:Lub teeb uas muaj npe sib npaug rau 60W tus qauv incandescent lossis LED feem ntau yuav pom tau tias dimmer dua li nws tsis yog - thaiv qhov sib npaug ntawm tib lub wattage thiab thov sib npaug.
* Compensating nrog Wattage:Txhawm rau ua tiav qhov xav tau qhov ci ci, cov neeg siv yuav tsum tau nruab siab dua -wattage xiav lub teeb thaiv qhov muag lossis siv cov khoom siv ntau dua, uas yuav cuam tshuam qee qhov kev txuag hluav taws xob.
* Kev ua haujlwm qis:Lumens per Watt (LPW), qhov ntsuas ntawm lub teeb qhov ua tau zoo, feem ntau qis dua rau lub teeb xiav thaiv LEDs piv rau cov qauv LEDs ntawm tib xim kub. Koj tau txais lub teeb tsawg dua rau tib yam hluav taws xob.
3. Qhov "False Sense of Security" thiab Misplaced Reliance:
* Limited Scope:Cov qij no feem ntau hais txog lub teeb xiav emitted los ntawmambient teeb pom kev zoo fixture nws tus kheej. Lawv uatsis muaj dab tsitxhawm rau thaiv qhov khaus, ze- ze ze lub teeb xiav tawm los ntawm cov ntxaij vab tshaus digital (xov tooj, ntsiav tshuaj, khoos phis tawj, TVs), uas feem ntau yog qhov tseem ceeb ntawm kev txhawj xeeb rau qhov muag thiab circadian cuam tshuam.
* Cwj Pwm Risk:Kev cia siab ib leeg ntawm cov qij no yuav ua rau cov neeg siv tsis quav ntsej txog cov tswv yim zoo dua:
* Kev Tswj Lub Sijhawm Saib Xyuas:Kev txo qhov screen raug rau yav tsaus ntuj tseem yog qhov tseem ceeb.
* Cov ntxaij lim dej:Cov kev daws teeb meem software (hmo hloov hom) lossis cov ntxaij lim dej lub cev yog ntau txoj hauv kev los txo cov teeb xiav ntawm cov khoom siv.
* Txoj Kev Teeb Pom Kev Zoo:Siv lub teeb ci, sov sov thaum yav tsaus ntuj tsis hais lub teeb hom, thiab ua kom lub teeb ci txaus thaum nruab hnub.
* Overestimation ntawm Kev Tiv Thaiv:Cov neeg siv yuav tsis raug xav tias lawv muaj kev tiv thaiv tag nrho los ntawm txhua qhov chaw teeb xiav, uas yuav ua rau lub sijhawm tshuaj ntsuam ntev dua lossis tsis quav ntsej txog lwm yam kev coj noj coj ua.
4. Tus nqi hwm thiab kev ua lag luam sib txawv:
* Tus nqi siab dua:Blue light blocking technology, tshwj xeeb phosphors, los yog lim ntxiv rau cov nqi tsim khoom. Cov qij no feem ntau kim dua li cov qauv LED sib piv.
* Kev tsis sib haum xeeb & kev thov:Lo lus "blue light blocking" tsis yog tswj nruj heev. Kev ua tau zoo sib txawv ntawm cov hom thiab cov khoom:
* Tsis muaj Standardization:Qhov kev txo qis twg yog "kev thaiv"? Puas yog 30%, 50%, 90%?
* Misleading Marketing:Qee lub qhov muag teev tsuas yog sov sov xim kub (xws li, 2700K) tus qauv LEDs ua lag luam raws li "blue light blocking," txawm tias lawv tseem muaj lub ncov xiav tseem ceeb piv rau cov khoom siv hluav taws xob tiag tiag.
* Tsis muaj Transparency:Reputable hom muab spectral zog faib graphs. Ntau tus tsis ua, ua rau nws tsis tuaj yeem txheeb xyuas cov lus thov. Nrhiav cov ntawv pov thawj zoo li IEC TR 62778 (RG0 zoo tshaj plaws).
5. Muaj feem cuam tshuam rau lub siab thiab kev ceeb toom (thaum nruab hnub):
* Kev Lag Luam Circadian - tawm:Thaum txo lub teeb xiav thaum yav tsaus ntuj muaj txiaj ntsig zoo rau kev pw tsaug zog, raug rau qhov txias dua, xiav - lub teeb pom kev zoo thaum nruab hnub yog qhov tseem ceeb rau kev txhawb siab, kev xav, thiab kev txawj ntse.
* Kev txhawj xeeb txog kev siv nruab hnub:Siv lub teeb xiav muaj zog thaiv qhov muag teevtxhua hnub, tshwj xeeb tshaj yog nyob rau hauv cov chaw ua hauj lwm hauv tsev los yog chaw ua hauj lwm, tej zaum yuav ua rau muaj kev xav ntawm lethargy los yog txo concentration los ntawm depriving cov neeg siv ntawm lub teeb xiav stimulating lawv circadian system xav tau. Lawv feem ntau tshwj xeeb tshaj yog siv rau yav tsaus ntuj thiab hmo ntuj.
6. Aesthetic txwv:
* Lub Amber Hue:Qhov sib txawv ntawm qhov sov, feem ntau daj / amber zoo li lub teeb xiav thaiv qhov muag tsis pom kev zoo. Ntau tus neeg siv pom cov xim no tsis zoo nkauj lossis tsis haum rau thaj chaw uas xav tau lub teeb dawb huv, ci, lossis nruab nrab (xws li, chav ua noj, chav dej, chav nres tsheb, chaw muag khoom).
Ua ib qho kev paub xaiv:
Lub teeb xiav thaiv cov qij LED yog cov cuab yeej tshwj xeeb, tsis yog kev daws teeb meem thoob ntiaj teb. Lawv tus nqi feem ntau yog nyob rau yav tsaus ntuj / hmo ntuj qhov chaw nyob (chaw pw, chav nyob) rau cov tib neeg uas nkag siab zoo rau lub teeb xiav pw tsaug zog - cuam tshuam cuam tshuam. Txawm li cas los xij, qhov txiaj ntsig no los ntawm tus nqi: kev cuam tshuam cov xim raug, txo qhov ci ntsa iab thiab ua haujlwm zoo, tus nqi siab dua, muaj peev xwm zoo nkauj tsis zoo, thiab kev pheej hmoo ntawm overestimating lawv tiv thaiv, tshwj xeeb tshaj yog tiv thaiv cov ntxaij vab tshaus.
Ua ntej kev nqis peev, xav txog:
Qhov Kev Siv Tseem Ceeb:Puas yog tiag tiag rau yav tsaus ntuj cua- nqes? Tsis txhob siv tag nrho -hnub hauv chaw ua haujlwm.
Xim Accuracy Xav Tau:Koj puas tuaj yeem zam qhov xim tsis zoo rau koj cov dej num?
Brightness yuav tsum tau:Koj puas kam siv ntau dua -wattage qhov muag teev lossis txais lub teeb dimmer?
Kev txheeb xyuas:Xaiv cov khoom muaj npe nrov uas muab cov ntaub ntawv spectral lossis tuav cov ntawv pov thawj qis - xiav - teeb pom kev nyab xeeb (IEC TR 62778 RG0).
Holistic Txoj Kev:Siv lawv liib feemntawm lub tswv yim uas suav nrog kev txwv lub sijhawm tshuaj ntsuam, cov cuab yeej lim dej, thiab kev tu lub teeb pom kev zoo, tsis yog kev kho ib leeg. Nkag siab txog kev ua lag luam -offs inherent nyob rau hauv uas txawv amber glow.
