Lub teeb emitting txoj cai ntawm LED teeb yog dab tsi?

Lub teeb emitting txoj cai ntawm LED teeb yog dab tsi? Lub teeb LED yog cov khoom siv hluav taws xob electroluminescent semiconductor nti, uas yog kho ntawm lub bracket nrog cov kua nplaum nyiaj los yog cov kua nplaum dawb, thiab tom qab ntawd txuas nrog lub nti thiab lub rooj tsav xwm hauv Circuit Court nrog nyiaj los yog kub xov hlau, thiab kaw nrog epoxy resin nyob ib ncig ntawm nws los tiv thaiv cov tub ntxhais hauv cov hlau. Kev ua haujlwm, lub plhaub tau teeb tsa kawg, yog li kev poob siab tsis kam ntawm LED teeb yog qhov zoo. 1. Lub teeb hlaws qauv Ib qho tseem ceeb tshaj plaws ntawm cov teeb pom kev zoo ntawm LED (Light Emitting Diode) teeb yog lub teeb hlaws qhov loj ntawm mung taum hauv lub teeb. Txawm hais tias nws qhov loj me me, nws txoj haujlwm tsis yog me me.

Tom qab zooming nyob rau hauv cov qauv ntawm LED teeb hlaws, peb yuav pom ib tug wafer qhov loj ntawm noob hnav noob. Cov qauv ntawm cov nti yog qhov nyuaj heev, thiab nws tau muab faib ua ob peb txheej: sab sauv Z txheej hu ua P-hom semiconductor txheej, nruab nrab txheej yog lub teeb-emitting txheej, thiab qis Z txheej hu ua N-hom semiconductor txheej. Yog li, LED teeb pom kev zoo li cas? 2. Lub hauv paus ntsiab lus ntawm lub teeb emission Los ntawm ib qho kev pom ntawm lub cev: thaum tam sim no dhau los ntawm lub wafer, cov electrons nyob rau hauv N-hom semiconductor thiab lub qhov nyob rau hauv P-hom semiconductor collide hnyav thiab recombine nyob rau hauv lub teeb-emitting txheej los tsim photons, uas emit zog nyob rau hauv daim ntawv ntawm photons (uas yog, lub teeb koj pom).

coj LED tseem hu ua lub teeb emitting diode, nws ntim yog me me thiab tsis yooj yim heev, nws tsis yooj yim rau siv ncaj qha. Yog li tus tsim tsim tau ntxiv lub plhaub tiv thaiv rau nws thiab muab ntim rau hauv, yog li tsim ib qho yooj yim-rau-siv LED teeb hlaws. Tom qab txuas ntau LED teeb hlaws ua ke, ntau lub teeb LED tuaj yeem tsim.

3. LED teeb ntawm cov xim sib txawv Semiconductors ntawm cov khoom sib txawv yuav tsim cov xim sib txawv ntawm lub teeb, xws li lub teeb liab, lub teeb ntsuab, lub teeb xiav thiab lwm yam. Txawm li cas los xij, tsis muaj cov khoom siv semiconductor tuaj yeem tawm lub teeb dawb kom deb li deb. Tab sis li cas cov dawb LED teeb hlaws peb feem ntau siv tsim? 4. Tiam ntawm cov teeb dawb LED Ntawm no peb yuav tsum tau hais txog tus Nobel laureate - Dr. Shuji Nakamura.

Nws tau tsim lub xiav LED, uas kuj tau tsim ib lub hauv paus rau cov LED dawb. Raws li qhov kev koom tes tseem ceeb no, nws tau txais txiaj ntsig Nobel Prize hauv Physics hauv 2014. Raws li kev ua li cas xiav LEDs hloov mus rau hauv cov LEDs dawb, qhov laj thawj loj tshaj plaws yog tias muaj txheej txheej ntxiv ntawm phosphor hauv cov nti.

Lub hauv paus ntsiab lus ntawm lub teeb-emitting tsis tau hloov ntau: ntawm ob txheej semiconductor, electrons thiab qhov sib tsoo thiab recombine los tsim xiav photons nyob rau hauv lub teeb-emitting txheej. Ib feem ntawm lub teeb xiav generated yuav dhau los ntawm cov fluorescent txheej thiab raug tso tawm ncaj qha; qhov seem seem yuav ntaus cov fluorescent txheej thiab cuam tshuam nrog nws los tsim cov duab daj. Lub teeb dawb yog tsim los ntawm kev sib xyaw (sib xyaw) xiav photons nrog daj photons.

Tam sim no, daim ntawv thov ntau ntawm LED teeb yog ntau heev. Siv Xinshengkai Optoelectronics ua piv txwv, LED lub teeb strips tsim los ntawm nws yog dav siv nyob rau hauv tsev thiab sab nraum zoov kho kom zoo nkauj, txoj kev scene layout, hniav nyiaj hniav kub txee, lub vaj, tsheb, pas dej ua ke, advertising kos npe, tsev so, khw malls, KTV, leisure qhov chaw, thiab lwm yam.
