Core Performance Advantages

Precise Colour Temperature Tuning: Ntsuas xim kub deviates los ntawm Tsawg dua los yog sib npaug li 0.1% ntawm lub hom phiaj tus nqi, kom ntseeg tau tias cov teeb pom kev zoo sib xws thiab ntuj tsim.

Siab CRI: Ra Ntau dua lossis sib npaug rau 90 thoob plaws txhua qhov xim kub, tshaj qhov tsawg kawg nkaus yuav tsum tau (Ra Ntau dua lossis sib npaug rau 70) rau cov teeb pom kev zoo sab hauv tsev thiab ua tau raws li tus qauv siab (Ra Ntau dua lossis sib npaug rau 85) rau xim - cov ntawv thov tseem ceeb.

Kev siv hluav taws xob zoo: Rated fais fab (20W) yog 30% qis dua cov tsoos 28W fluorescent downlights, nrog luminous efficiency Ntau dua los yog sib npaug rau 53 lm / W.

Wireless yooj yim: ZigBee tswj tshem tawm qhov xav tau ntawm txoj hlua txuas, txhawb kev hloov kho tej thaj chaw deb txog li 100 meters. Lub mesh network ua kom ntseeg tau cov teeb liab kis tau tus mob txawm nyob hauv cov tsev loj.

Kev ua haujlwm ruaj khov: Cov tsav tsheb tam sim no tsis tu ncua thiab kev tiv thaiv kev tiv thaiv (overcurrent, overvoltage, overtemperature) ncua lub neej mus txog 50,000 teev (L70B50), txo cov nqi kho.

Daim ntawv thov Scenario

Teeb pom kev zoo nyob: Kho xim kub raws li lub sijhawm nruab hnub- sov dawb (2900K) rau yav tsaus ntuj los txhawb kev so, txias dawb (4500K) rau yav sawv ntxov los txhim kho kev ceeb toom. Cov chav pw thiab chav nyob tau txais txiaj ntsig los ntawm qhov chaw sov so ntawm cov xim dawb, thaum chav ua noj thiab chav ua haujlwm hauv tsev siv cov xim dawb kom pom kev zoo dua.

Teeb pom kev lag luam: Cov khw muag khoom tuaj yeem hloov xim kub kom pom cov xim ntawm cov khoom lag luam (xws li, sov dawb rau khaub ncaws, txias dawb rau cov khoom siv hluav taws xob). Cov rooj sib tham txhawb nqa kev hloov pauv hloov pauv rau kev nthuav qhia (txias dawb) thiab so (sov dawb).

Teeb pom kev tshwj xeeb: Xim luam ntawv studios thiab kos duab kos duab siv lub siab CRI (Ra Ntau dua lossis sib npaug ntawm 90) los xyuas kom meej cov xim luam tawm, tseem ceeb heev rau kev ua haujlwm.

Kev daws teeb meem

Txhawm rau daws qhov tsis sib xws ntawm cov xim, calibrate LED xim ua haujlwm siv lub spectrophotometer (xws li, PMS-50) ua ntej sib dhos, ua kom muaj kev sib raug zoo nrog CIE txoj cai sib xyaw. Rau ZigBee teeb liab teeb meem, siv mesh networking los ntxiv cov repeaters nyob rau hauv loj qhov chaw, thiab xaiv 2.4GHz channel 11/13 kom tsis txhob Wi-Fi cuam tshuam. Tiv thaiv flicker los ntawm kev siv siab - zaus PWM (Ntau dua lossis sib npaug rau 20kHz) thiab cov tsav tsheb tam sim no tsis tu ncua nrog Tsawg dua lossis sib npaug li 3% tam sim no ripple. Txhawm rau kom muaj txiaj ntsig zoo ntawm qhov kub thiab txias, ua kom zoo dua cov amber -dawb-xiav piv (xws li 35:50:15 rau 2900K) es tsis txhob cia siab rau liab phosphor. Yog hais tias lub wireless - tswj dawb LED downlight tsis teb, xyuas lub ZigBee module lub hwj chim mov (3.3V) thiab qhov chaw sib txuam; pib dua tus tswv tswj hwm kom rov- tsim kev sib txuas lus. Kev saib xyuas tsis tu ncua, xws li ntxuav lub lens LED (plua plav txo cov luminous efficiency los ntawm 10-15%), kuj tseem khaws kev ua haujlwm. Ib txwm siv cov ntawv pov thawj ZigBee (piv txwv li, CC2530) thiab cov LEDs zoo kom ntseeg tau.
