Tsoos LED teeb qhov chaw
Ib txwmLED teebCov peev txheej txais yuav ib hom ntim ntim ib zaug, muaj cov chips LED, cov xov hlau kub, cov hlua khi, cov hmoov fluorescent, thiab cov ntim ntim colloids. Lub nti yog tsau rau hauv qab ntawm lub khob ntim nrog cov nplaum nplaum, thiab cov hlau kub txuas cov nti electrode rau tus tuav tus pin. Cov hmoov fluorescent yog tov nrog silicone los npog lub nti rau spectral conversion.
Txoj kev ntim khoom no tau tsim ntau hom ntaub ntawv xws li kev ntxig ncaj qha thiab qhov chaw mount, tab sis qhov tseem ceeb nws yog ib qho kev sib txuas ntawm cov teeb pom kev ywj pheej, xws li cov hlaws tawg uas yuav tsum tau ua tib zoo txuas rau hauv koob kom ci. Txawm li cas los xij, thaum tsim lub teeb pom kev loj loj, qhov nyuaj ntawm qhov kho qhov muag tau nce exponentially, ib yam li kev tsim lub tsev zoo nkauj uas yuav tsum muaj ntau lub zog thiab cov khoom siv los sib sau ua ke thiab sib xyaw ua ke txhua lub cib thiab pob zeb.
COB light source
COB lightCov khoom tawg los ntawm kev ntim khoom ib txwm muaj thiab siv ntau cov nti ncaj qha kev sib txuas thev naus laus zis kom ncaj qha nyiaj ntau txhiab mus rau txhiab tus LED chips mus rau cov hlau raws li cov ntawv luam tawm Circuit boards lossis ceramic substrates.Cov chips yog hluav taws xob sib cuam tshuam los ntawm high-density wiring, thiab ib lub teeb luminescent nto yog tsim los ntawm npog tag nrho cov silicon gel txheej uas muaj fluorescent zoo li pearledding architecture. Lub cev sib txawv ntawm ib tus neeg LEDs thiab ua tiav kev sib koom ua ke ntawm optics thiab thermodynamics.
Piv txwv li, Lumileds LUXION COB siv eutectic soldering thev naus laus zis los ua ke 121 0.5W chips ntawm lub voj voog substrate nrog txoj kab uas hla ntawm 19mm, nrog rau tag nrho lub zog ntawm 60W. Lub nti sib nrug yog compressed rau 0.3 hli, thiab nrog kev pab los ntawm ib tug tshwj xeeb reflective kab noj hniav, lub uniformity ntawm lub teeb tis tshaj 90%. Qhov kev ntim khoom sib xyaw no tsis tsuas yog ua kom yooj yim rau cov txheej txheem tsim khoom, tab sis kuj tsim ib daim ntawv tshiab ntawm "lub teeb ci raws li module", muab lub hauv paus hloov pauv rauteeb pom kev zootsim, ib yam li muab pre-ua exquisite modules rau teeb pom kev zoo designers, zoo heev txhim kho efficiency ntawm tsim thiab ntau lawm.

Optical zog:Kev hloov pauv los ntawmtaw tes teebqhov chaw rau saum lub teeb qhov chaw
Ib leeg LED
Ib qho LED tsuas yog ib qho tseem ceeb ntawm Lambertian lub teeb ci, emitting lub teeb ntawm lub kaum sab xis ntawm 120 °, tab sis lub teeb siv hluav taws xob faib qhia tau hais tias qhov qis qis qis qis ntawm qhov chaw, zoo li lub hnub qub ci ntsa iab, ci ntsa iab tab sis tawg me ntsis thiab tsis sib haum xeeb. Mus ntsib tusteeb pom kev zoocov kev xav tau, nws yog qhov tsim nyog los hloov kho lub teeb faib nkhaus los ntawm kev tsim kho qhov muag thib ob.
Kev siv TIR lo ntsiab muag nyob rau hauv lub lens system tuaj yeem compress lub emission lub kaum sab xis mus rau 30 °, tab sis lub teeb efficiency poob mus txog 15% -20%; Parabolic reflector nyob rau hauv lub tswv yim reflector tuaj yeem txhim kho lub teeb pom kev hauv nruab nrab, tab sis nws yuav tsim cov teeb pom kev zoo; Thaum sib txuas ntau lub LEDs, nws yog ib qho tsim nyog yuav tsum muaj qhov sib nrug txaus kom tsis txhob muaj xim sib txawv, uas tuaj yeem ua rau lub teeb tuab. Nws zoo li kev sim ua ib daim duab zoo meej nrog cov hnub qub nyob rau hmo ntuj, tab sis nws yog ib qho nyuaj kom tsis txhob muaj qhov tsis xws luag thiab ntxoov ntxoo.
Integrated Architecture COB
Kev sib xyaw ua ke ntawm COB ib txwm muaj cov yam ntxwv ntawm qhov chawteebQhov chaw, zoo li lub galaxy ci ntsa iab nrog lub teeb pom kev zoo thiab lub teeb mos.Multi nti ntom txheej tshem tawm cov chaw tsaus, ua ke nrog cov tshuab micro lens array, tuaj yeem ua kom pom kev sib txawv> 85% nyob rau hauv qhov kev ncua deb ntawm 5m; Los ntawm roughening lub substrate nto, lub emission lub kaum sab xis yuav txuas mus rau 180 °, txo qhov glare index (UGR) kom qis dua 19; Nyob rau hauv tib lub luminous flux, optical expansion ntawm COB yog txo los ntawm 40% piv rau LED arrays, ho simplifying lub teeb tis tsim.teeb pom kev zooscene, ERCO's COB khiavteebua tiav 50: 1 illumination piv ntawm qhov kev ncua deb ntawm 0.5 meters los ntawm cov lo ntsiab muag dawb, zoo kawg nkaus daws qhov tsis sib xws ntawm cov teeb pom kev zoo thiab cov ntsiab lus tseem ceeb.

Thermal Management Solution:innovation los ntawm lub zos tshav kub dissipation rau system theem tshav kub conduction
Tsoos LED teeb qhov chaw
Ib txwm LEDs txais yuav plaub theem thermal conduction txoj kev ntawm "chip khoom txheej txhawb nqa PCB", nrog rau cov thermal tsis sib xws, zoo li txoj kev winding, uas cuam tshuam cov cua sov sai sai. Nyob rau hauv cov nqe lus ntawm kev sib txuas thermal kuj, muaj kev sib cuag thermal kuj ntawm 0.5-1.0 ℃ / W ntawm cov nti thiab lub bracket; Nyob rau hauv cov nqe lus ntawm cov khoom siv thermal kuj, thermal conductivity ntawm FR-4 board tsuas yog 0.3W / m · K, uas dhau los ua ib qho fwj rau cov cua sov dissipation; Raws li cov txiaj ntsig sib xyaw, cov hotspots hauv zos tuaj yeem nce qhov sib txuas ntawm qhov kub ntawm 20-30 ℃ thaum ntau lub LEDs sib xyaw ua ke.
Kev sim cov ntaub ntawv qhia tau hais tias thaum lub ambient kub mus txog 50 ℃, lub teeb lwj tus nqi ntawm SMD LED yog peb zaug sai dua li ntawm 25 ℃ ib puag ncig, thiab lub neej luv luv mus rau 60% ntawm L70 tus qauv. Ib yam li ntev raug rau scorching hnub, kev ua tau zoo thiab lifespan ntawmLED teebqhov chaw yuav raug txo kom tsawg.
COB light source
COB txais yuav peb-theem conduction architecture ntawm "chip substrate tshav kub dab dej", ua tiav ib tug leap ntawm thermal tswj zoo, zoo li tso ib tug dav thiab tiaj txoj kev loj rauteebqhov chaw, tso cua sov kom sai thiab dissipated. Nyob rau hauv cov nqe lus ntawm substrate innovation, thermal conductivity ntawm txhuas substrate ncav cuag 2.0W / m · K, thiab hais tias ntawm aluminium nitride ceramic substrate ncav cuag 180W / m · K; Nyob rau hauv cov nqe lus ntawm niaj hnub tsim hluav taws xob, ib tug niaj hnub cua sov txheej yog nteg nyob rau hauv lub nti array los tswj qhov kub ntawm qhov sib txawv nyob rau hauv ± 2 ℃; Nws kuj yog sib xws nrog cov kua cua txias, nrog rau lub tshav kub dissipation muaj peev xwm txog li 100W / cm ² thaum lub substrate los rau hauv kev sib cuag nrog cov kua txias phaj.
Nyob rau hauv daim ntawv thov ntawm lub tsheb headlights, lub Osram COB lub teeb qhov chaw siv thermoelectric sib cais tsim kom stabilize lub hlws ris kub hauv qab no 85 ℃, ua tau raws li cov kev cia siab ntawm AEC-Q102 automotive qauv, nrog ib tug lifespan ntawm ntau tshaj 50000 teev. Ib yam li kev tsav tsheb ntawm kev kub ceev, nws tseem tuaj yeem muab kev ruaj khov thiabtxhim khu kev qha teeb pom kev zoorau cov neeg tsav tsheb, ua kom muaj kev nyab xeeb ntawm kev tsav tsheb.
