Xaiv txoj caiLED teeb pom kev zoo rau chav kawmNws yog ib qho tseem ceeb rau cov tub ntxhais kawm qhov muag kev noj qab haus huv, ua kom pom tseeb, thiab kev kawm tau zoo. Raws li cov qauv kev lag luam thiab cov lus pom zoo hauv kev lag luam, ntawm no yog cov kev cai tseem ceeb thiab cov kev pom zoo:
I. Core Technical Standards for Classroom LED Lights
Illuminance & Uniformity
Lub Rooj Illumination: Ntau dua los yog sib npaug rau 300 lux nruab nrab, uniformity Ntau dua los yog sib npaug rau 0.7 .
Blackboard Illumination: Ntau dua los yog sib npaug rau 500 lux nruab nrab, uniformity Ntau dua los yog sib npaug rau 0.8 .
Piv txwv: BENWEI Teeb pom kev zoos ntev-bar tsim ua tiav 2,000 lux chaw ci ntsa iab thiab npog 1.2m rooj sib npaug.
Xim kub (CCT)
Optimal Range: 4000K–5000K ( nruab nrab rau txias dawb), simulating ntuj kaj thaum sawv ntxov .
Tsis txhob muaj kev kub ntxhov:
4000K: Xiav- lub teeb nplua nuj cuam tshuam cov circadian rhythms.
<3300K: Overly warm light induces drowsiness .
High Color Rendering Index (CRI)
Kev xav tau: Ra ≥95 (preferably R9 >90 rau qhov tseeb liab) kom ntseeg tau cov phau ntawv / duab tso saib cov xim tiag.
Kev cuam tshuam: Tsawg CRI distorts xim kev nkag siab, cuam tshuam rau kev kos duab / kev tshawb fawb.
Glare Tswj & UGR ntsuas
Hom phiaj: UGR Tsawg dua lossis sib npaug rau 19 (qis dua yog qhov zoo dua). Sivdiffusion panels + daim phiaj baffleskom tawg lub teeb thiab tshem tawm glare.
Technology: Ouman ob - txheej tiv thaiv - glare tsim txo UGR kom tsawg dua lossis sib npaug rau 14 .
Flicker-Dawb & Xiav Teeb Kev Nyab Xeeb
Daim ntawv pov thawj: RG0 (zero blue light hazard) and flicker frequency >3,125 Hz.
Advanced daws: Violet-zoo siab LEDs (xws li Moonlight, Jienengtong) tshem tawm lub teeb xiav ntawm qhov chaw .
II. Cov yam ntxwv tseem ceeb rau kev siv chav kawm
Durability: 50, 000+ teev lifespan, IP- ntsuas plua plav / kab tiv thaiv .
Zog Efficiency: LED siv ~ 50% tsawg zog dua fluorescents.
Ntse Tswj: Nws pib- dimming sensors kho qhov ci raws hnub ci.
Ergonomic Tsim: Rotatable caj npab rau saj zawg zog teeb lub kaum sab xis.
III. Pom zoo Hom & Qauv
Table: Sab saum toj Chav Kawm -Tshwj xeeb LED Solutions
| Hom | Tus Qauv Tseem Ceeb | Nta | Zoo tshaj rau |
|---|---|---|---|
| BENWEI teeb pom kev zoo | Ntuj Teeb Series | 4000K / 5000K, RG0, Ra98, UGR Tsawg dua lossis sib npaug rau 14 | Cov chav kawm loj, labs |
IV. Daim ntawv pov thawj & Ua raws cai
Xyuas kom cov khoom sib ntsib:
Tuam Tshoj Compulsory Certification (CCC) .
GB 7793-2010chav kawm teeb pom kev zoo qauv.
Zog Hnub Qublos yog hauv zos efficiency benchmarks.
V. Cov lus qhia txog kev siv
Ua ntej teeb pom kev zoo ib yamtshaj qhov ci ci siab tshaj plaws kom tsis txhob "kub chaw."
Nruab blackboard-cov teeb tshwj xeebntawm 30℃-45℃kaum los tiv thaiv glare.
Ua ke ambient + ua haujlwm teeb pom kev zoo: Qab nthab vaj huam sib luag + rooj teeb kom yooj yim.
Professional calibration: Post- kev teeb tsa lux kuaj xyuas kom ua raws li .
Tswv yim Pro: Rau cov chav kawm digitally hnyav (xws li, ntsiav tshuaj/smartboards), xaiv lub teeb nrog<15% blue light emission (certified RG0) to reduce digital eye strain .
Txhawm rau kom tau txais txiaj ntsig zoo, sab laj cov kws tshaj lij teeb pom kev zoo (piv txwv li, Moonlight txoj kev kawm faib) rau kev tsim kho. Kev nqis peev hauv cov ntawv pov thawj, siab - LEDs zoo txhim kho kev kawm tau zoo los ntawm 12–18% vim txo qhov muag qaug zog thiab kev xav zoo dua
