Tunets LED cov kev hloov kho raws li CSP-COB
Abstract: Kev tshawb fawb tau qhia txog kev sib txheeb ntawm cov xim ntawm lub teeb pom kev zoo.A Cov kev xav tau zoo tshaj plaws hauv lub teeb pom kev zoo tshaj plaws rau ib puag ncig lub hnub ci ntsa iab nrog lub hnub ci ntsa iab nrog cov cri ntau, tab sis yog qhov zoo kawg nkaus attuned rau tib neeg rhiab heev. Ib tug tib neeg lub nroog lub teeb (HCl) yuav tsum tau ua rau engineered nyob rau qhov hloov chaw xws li ntau cov chaw xws li ntau cov chaw, chav kawm, kev saib xyuas kev noj qab haus huv thiab kev saib xyuas kev noj qab haus huv. Tunets LED modules tau tsim los ntawm kev sib txuas nti nplai pob khoom (CSP) thiab nti ntawm Board (cob qhia). CSPs tau muab tso ua ke rau ntawm COB Board kom ua tiav lub zog siab thiab cov xim muaj xim zoo nkauj ntawm lub hnub ci ntsa iab thaum nruab hnub ua kom lub teeb ci ntsa iab thaum yav tsaus ntuj, Daim ntawv no cov qauv, cov txheej txheem, thiab kev ua tau zoo ntawm LED cov qauv thiab nws daim ntawv thov hauv sov- tsaug kev teeb thiab pendant teeb.

Lub hauv paus rau phau ntawv
Tus coj raws li peb paub tias nws tau nyob ib puag ncig tau 50 xyoo. Cov kev txhim kho tshiab ntawm dawb yog dab tsi rau hauv cov pej xeem qhov muag ua cov khoom siv hauv lub zog thiab lub neej ntev, tab sis kuj qhib lub qhov rooj rau Kev tsim qauv tshiab rau cov ntawv sau thiab xim xim.Tus yog ob txoj kev tsim lub teeb dawb lub teeb ci dawb.one Thawj cov xim-liab, ntsuab, thiab xiav-thiab tom qab ntawd tov cov khoom muaj teeb ci lossis virochromatic LED teeb kom dav lub teeb dawb ,, ntau nyob rau hauv tib txoj kev fluorescent Lub teeb BGB ua haujlwm yog qhov tseem ceeb kom nco ntsoov tias 'whiteness'of lub teeb tsim yog qhov tseem ceeb uas nws yuav tsis tsim nyog xav tias nws yog lub teeb dawb.
Cov teeb carting ntse yog thaj chaw tseem ceeb hauv lub tuam tsev tam sim no thiab cov teeb meem ntawm cov qauv sib txuas lus tau siv yog tias cov qauv kev sib txuas lus zoo yog siv ntau hom khoom lag luam , Xws li knx) bacnetp ', dali, zigbee-zhazba', plc-Lonworks, thiab lwm yam khoom lag luam tseem ceeb hauv txhua cov khoom yog tias lawv tsis tuaj yeem cuam tshuam nrog txhua lwm yam (piv txwv li, tsis muaj peev xwm tsawg thiab kev sib zog).
LED Luminaires nrog lub peev xwm xa sib txawv ntawm lub teeb pom kev zoo nyob rau ntawm lub teeb pom kev zoo nyob rau hauv kev ua haujlwm thiab yuav tsum muaj qee yam kev ua haujlwm los ntawm Tshwj xeeb yog lub installation yog kom ua tiav. Muaj peb theem pib muaj xim hom hauv LED Luminaires: Dawb tuning, thiab tag nrho cov pawg xa tawm siv ZigBee, Wi-nkaus, Bluetooth lossis Lwm cov txheej txheem, thiab yog cov tawv tawv kom ua kom muaj zog.Thaum ntawm cov kev daws teeb meem los hloov cov xim los yog CCT kom tau raws li tib neeg lub ntsej muag sib dhos.
Cov Lus Qhia Txog Lub Tebchaws Circadian
Nroj tsuag thiab tsiaj cov qauv kev coj cwj pwm ntawm kev coj cwj pwm thiab kev hloov pauv ntawm lub sijhawm 24-teev
Lub Circadian atherosclerosis yog tswj los ntawm Melatonin uas yog ib qho ntawm cov tshuaj hormones loj tsim nyob rau hauv lub hlwb. Thiab nws induces pw tsaug zog kuj.melanopsin cov receptors teeb tsa lub teeb ci ntsa iab ntawm lub teeb ci ntsa iab ntawm lub teeb thiab cuam tshuam rau cov kev pw tsaug zog xiav. Circadian desynchronization txwv tsis pub muaj lub cev tag nrho nkag mus rau ntau theem ntawm kev pw tsaug zog, uas yog lub sijhawm rov qab tseem ceeb rau tib neeg lub cev.Frurthermore, qhov cuam tshuam ntawm cov kev cuam tshuam circadian txuas ntxiv dhau lub siab lub hnub thiab pw thaum hmo ntuj.
Hais txog kev sib dhos muaj roj ntsha hauv tib neeg tuaj yeem ntsuas tau ntau txoj hauv kev, thiab lub cev me me, cov tub ntxhais lub cev pw ntawm cov lus sib dhos rau hauv ntiaj teb, vim hais tias tus Lub teeb siv, Spectrum faib, sijhawm sijhawm thiab sijhawm tuaj yeem cuam tshuam tib neeg lub ntsej muag circavian.Qhov kev cuam tshuam rau lub moos txhua hnub ntxiv. Lub sijhawm ntawm lub teeb kis tau tuaj yeem ua tiav lossis ncua lub moos circadian feem ntau yuav cuam tshuam rau tib neeg lub ntsej muag thiab kev nplij siab rau 555nm (thaj av ntsuab). Yog li yuav siv lub tunt cct thiab siv los txhim kho lub neej zoo yog ua ntau dua Tseem Ceeb.Color tuneed nrog kev pom kev hnov thiab tswj cov kab ke tuaj yeem tsim kho kom tau raws li cov kev ua tau zoo, muaj teeb meem zoo.

Cov Pob Tsim
Thaum koj kho qhov ci ci ntawm cov pa halogen
Teeb, xim yuav raug hloov. Txawm li cas los xij, cov lus siv tau tsis muaj peev xwm los ua kom khov kho kub thaum hloov lub ci ci, emulating ib qho kev hloov pauv tib yam ntawm qee qhov teeb pom kev zoo. Nyob rau hnub ua ntej, muaj ntau lub qhov muag yuav siv coj nrog CCT LEDs ua ke ntawm PCB boardto
Hloov cov xim teeb pom kev zoo los ntawm kev hloov tsav tsheb tam sim no. Nws xav tau kev tsim lub teeb tsim qauv teeb tsa los tswj CCT, uas tsis yooj yim ua haujlwm rau Luminaire Cov Chaw Tsim Tshuaj Ua kom txaus rau ob qho xim xim thiab cov chaw teeb pom kev zoo, tunable xim COBs tshwm hauv kev ua lag luam.
Nws muaj peb cov qauv theem pib ntawm cov hom xim xim, qhov ua ntej, nws siv cov kab ke sov rau ntawm PCB Board nrog ntau cov kab txaij ntawm CCCT sib txawv Silicoas tau qhia hauv daim duab
3.Qhov chaw ua haujlwm, txoj hauv kev thib peb yog noj los ntawm kev sib xyaw ua kom sov CSTStrate.then Solder Sublicone dampective silicone dampected silicone rais-dawb csps thiab xiav flip-chips.finally , Nws yog sau nrog phosphor muaj siliconono ua kom cov xim dual ua tiav raws li qhia hauv Fig.4.
Fig.4 Sov Xim CSP thiab xiav Flip nti Cob (qauv 3- Finech txhim kho)
Muab piv rau cov qauv 3, tus qauv 1 muaj peb qhov tsis zoo:
(a) Cov xim sib xyaw ntawm cov sib txawv csp teeb nyob rau hauv cov CCTs sib txawv tsis yog kev lom zem vim yog cov chips ntawm CSP lub teeb ci;
(b) CSP lub teeb ci yog qhov yooj yim nrog kev kov lub cev;
(c) Qhov sib txawv ntawm txhua qhov CSP lub teeb ci yog ib qho yooj yim los mus rau cov hmoov av los ua kom muaj kev txiav lumen;
Tus qauv2 kuj muaj nws qhov tsis zoo:
(a) nyuaj rau kev tsim qauv tswj hwm thiab tswj cov move;
(b) Cov xim sib xyaw ntawm cov ntu sib txawv tsis yog hnav zoo, tshwj xeeb tshaj yog rau cov qauv ze.
Daim duab 5 sib piv Mr 16 teeb tsa lub teeb nrog lub teeb ci ntawm cov qauv 3 (sab laug) thiab qauv 1 (txoj cai). Los ntawm daim duab, peb tuaj yeem nrhiav tus qauv 1 muaj lub teeb ntxoov ntxoo nyob rau hauv nruab nrab ntawm thaj chaw emitting, thaum lub sij hawm theluminous faib tawm ntawm cov qauv 3 yog ib qho zoo dua qub.
Cov Ntawv Thov
Hauv peb txoj kev siv cov qauv 3, muaj ob txoj kev sib txawv Circuit Court tsim rau lub teeb xim thiab lub teeb ci ntsa iab. Nyob rau hauv ib tug-channel Circuit uas muaj ib txoj hlua kev tsav tsheb yooj yim, txoj hlua dawb thiab xiav flip-nti tau txuas nrog CSP txoj hlua. Nrog lub resistor, tus tsav tsheb tam sim no tau faib ntawm CSP thiab cov xim xiav. Qhia tau cov xim sib tw tau muaj nyob hauv cov yeeb yaj kiab ntawm cov yeeb yaj kiab. CCct ua kom cov tsav tsheb tam sim no. Peb tau paub tias ob txoj kev coj tus cwj pwm nrog ib qho emulating cov pa halogen bulband Lwm txoj kev sib tw ntxiv. Lub tunable CCT li cas yog los ntawm 1800K txog 3000k.

Lwm cov qauv tsim siv cov txheej txheem dual-chancuit uas catt tungle sprograrically muab cais tawm ntawm ib qho-channel thiab ci xim thiab ci ci yog tuned los ntawm Tsav ob lub voj voog ntawm qhov xav tau qib tam sim no thiab piv. Nws tuaj yeem raug kaw los ntawm 3000k txog 5700KAS tau qhia hauv daim duab 8 ntawm ci dual-channel Cod qauv hloov txij thaum sawv ntxov mus rau yav tsaus ntuj. circuits, no lub teeb pom kev zoo no ua rau lub teeb xiav thaum nruab hnub thiab txo cov neeg xiav, txhawb nqa tib neeg txoj kev ua tau zoo thiab tib neeg kev ua tau zoo thiab raws li cov teeb tsa teeb pom kev zoo.
Lub ntsiab
Tunets LED modules tau tsim los ntawm kev sib txuas
Ntiav cov pob khoom (CSP) thiab nti ntawm Board (cob) thev naus laus zis. CSPSNAL XA UNPIPS tau muab tso rau ntawm COB Board kom ua tiav cov qauv hluav taws xob siab thiab cov qauv xim, cov qauv xim, dual-channel yog siv los ua kom tiav los ua kom tiav CCTs zoo li kev lag luam teeb pom kev zoo. Ib leeg-channel qauv yog siv kom ua tiav Dim-to-sov ua haujlwm emulating halogen halogen halogen halogen nyob rau hauv cov ntawv thov thiab tos txais tsev.
