Hauv nthwv dej ntawm kev lag luam LED hloov kho dua tshiab rau LED thev naus laus zis, qhov tseeb ntawm cov khoom siv sib txuas tuag ncaj qha txiav txim siab qhov txiaj ntsig ntawm cov ntim khoom nti thiab kev ua tau zoo ntawm cov khoom. ZHHIMG, nrog nws txoj kev sib koom ua ke ntawm cov ntaub ntawv tshawb fawb thiab kev tsim khoom meej, muab kev txhawb nqa tseem ceeb rau cov khoom siv sib txuas tuag LED thiab tau dhau los ua lub zog tseem ceeb tsav tsheb tsim kho tshiab hauv kev lag luam.
Kev ruaj khov thiab kev ruaj khov siab heev: Xyuas kom meej tias qhov tseeb ntawm kev sib txuas ntawm cov pwm hauv micron-level
Cov txheej txheem sib txuas ntawm cov LEDs xav tau kev sib txuas ntawm cov chips me me (nrog qhov me tshaj plaws ncav cuag 50μm × 50μm) rau ntawm lub substrate. Txhua qhov kev hloov pauv ntawm lub hauv paus yuav ua rau kev sib txuas ntawm cov tuag hloov pauv. Qhov ceev ntawm cov khoom siv ZHHIMG ncav cuag 2.7-3.1g / cm³, thiab nws lub zog compressive tshaj 200MPa. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv, nws tuaj yeem tiv taus kev co thiab kev poob siab los ntawm kev txav mus los ntawm zaus siab ntawm lub taub hau sib txuas tuag (txog li 2000 zaug ib feeb). Qhov ntsuas tiag tiag ntawm lub tuam txhab LED ua lag luam qhia tau hais tias cov khoom siv sib txuas tuag siv lub hauv paus ZHHIMG tuaj yeem tswj tau qhov sib txawv ntawm cov chip hauv ± 15μm, uas yog 40% siab dua li cov khoom siv hauv paus ib txwm muaj thiab ua tau raws li cov kev cai nruj ntawm JEDEC J-STD-020D tus qauv rau kev sib txuas tuag raug.
Kev ruaj khov thermal zoo heev: daws qhov teeb meem ntawm qhov kub ntawm cov khoom siv nce siab
Kev siv cov khoom siv sib txuas ua ke mus sij hawm ntev tuaj yeem ua rau qhov kub hauv zos nce siab (txog li ntau dua 50 ℃), thiab qhov nthuav dav thermal ntawm cov khoom siv niaj hnub tuaj yeem hloov pauv qhov chaw sib piv ntawm lub taub hau sib txuas ua ke thiab lub substrate. Tus coefficient ntawm thermal nthuav dav ntawm ZHHIMG yog qis li (4-8) × 10⁻⁶ / ℃, uas tsuas yog ib nrab ntawm cov hlau cam khwb cia. Thaum lub sijhawm ua haujlwm siab tas mus li 8-teev, qhov kev hloov pauv ntawm lub hauv paus ZHHIMG yog tsawg dua 0.1μm, ua kom muaj kev tswj hwm qhov siab thiab qhov siab ntawm kev sib txuas ua ke ntawm cov tuag kom tiv thaiv kev puas tsuaj ntawm cov chip lossis kev sib txuas tsis zoo los ntawm kev hloov pauv thermal. Cov ntaub ntawv los ntawm lub Hoobkas ntim khoom LED Taiwanese qhia tau hais tias tom qab siv lub hauv paus ZHHIMG, qhov kev puas tsuaj ntawm cov tuag sib txuas tau poob qis los ntawm 3.2% mus rau 1.1%, txuag tau ntau dua 10 lab yuan hauv cov nqi txhua xyoo.
Cov yam ntxwv ntawm kev co siab: Tshem tawm kev cuam tshuam kev co
Qhov kev co 20-50Hz uas tsim los ntawm kev txav mus los ceev ceev ntawm lub taub hau tuag, yog tias tsis raug txo qis raws sijhawm, yuav cuam tshuam rau qhov tseeb ntawm qhov chaw ntawm lub nti. Cov qauv siv lead ua sab hauv ntawm ZHHIMG muab rau nws nrog kev ua haujlwm zoo heev, nrog rau qhov piv ntawm damping ntawm 0.05 txog 0.1, uas yog 5 txog 10 npaug ntawm cov khoom siv hlau. Pom zoo los ntawm ANSYS simulation, nws tuaj yeem txo qhov kev co amplitude ntau dua 90% hauv 0.3 vib nas this, ua kom zoo xyuas kom meej tias cov txheej txheem sib txuas tuag ruaj khov, ua rau lub kaum sab xis yuam kev tsawg dua 0.5 °, thiab ua tau raws li cov kev cai nruj ntawm LED chips rau qib tilt.
Kev ruaj khov tshuaj lom neeg: Hloov tau rau qhov chaw tsim khoom hnyav
Hauv cov chaw ua haujlwm ntim khoom LED, cov tshuaj xws li cov kua dej thiab cov tshuaj ntxuav feem ntau siv. Cov ntaub ntawv yooj yim yog yooj yim rau xeb, uas tuaj yeem cuam tshuam rau lawv qhov tseeb. ZHHIMG yog tsim los ntawm cov zaub mov xws li quartz thiab feldspar. Nws muaj cov khoom siv tshuaj ruaj khov thiab zoo heev tiv taus acid thiab alkali corrosion. Tsis muaj tshuaj lom neeg pom tseeb hauv pH ntau ntawm 1 txog 14. Kev siv ntev yuav tsis ua rau muaj kev sib kis ntawm cov hlau ion, ua kom ntseeg tau tias qhov huv ntawm qhov chaw sib txuas tuag thiab ua tau raws li cov kev cai ntawm ISO 14644-1 Chav Kawm 7 chav huv, muab kev lees paub rau kev ntim khoom LED siab.
Kev ua tiav precision: Ua tiav high-precision sib dhos
Siv cov thev naus laus zis ua tiav ultra-precision, ZHHIMG tuaj yeem tswj tau qhov tiaj tiaj ntawm lub hauv paus hauv ± 0.5μm / m thiab qhov roughness ntawm qhov chaw Ra≤0.05μm, muab cov ntaub ntawv teeb tsa meej rau cov khoom siv meej xws li lub taub hau sib txuas tuag thiab lub zeem muag. Los ntawm kev sib koom ua ke nrog cov lus qhia linear siab (rov ua qhov tseeb ± 0.3μm) thiab laser rangefinders (kev daws teeb meem 0.1μm), qhov tseeb ntawm qhov chaw ntawm cov khoom siv sib txuas tuag tau raug tsa mus rau qib ua tus thawj coj hauv kev lag luam, pab txhawb kev tshawb fawb txog kev siv tshuab rau LED cov lag luam hauv LED teb.
Nyob rau lub caij nyoog tam sim no ntawm kev txhim kho sai hauv kev lag luam LED, ZHHIMG, siv nws ob qho txiaj ntsig hauv kev ua tau zoo ntawm cov khoom siv thiab cov txheej txheem tsim khoom, muab cov kev daws teeb meem ruaj khov thiab txhim khu kev qha rau cov khoom siv sib txuas tuag, txhawb nqa cov ntim LED mus rau qhov tseeb dua thiab ua haujlwm tau zoo, thiab tau dhau los ua lub zog tseem ceeb rau kev hloov kho thev naus laus zis hauv kev lag luam.
