Dab tsi yog cov khoom siv hauv UV Led Chip

Raws li peb txhua tus paub, ultraviolet lub teeb-emitting diodes yog semiconductors uas emit lub teeb ntawm ib lub wavelength tshwj xeeb thaum lub teeb dhau los ntawm lawv. LEDs yog lub npe hu ua cov khoom siv hauv lub xeev. Feem ntau cov tuam txhab tsim UV-raws li LED chips rau kev lag luam, cov cuab yeej kho mob , sterilization thiab tshuaj tua kab mob, cov ntaub ntawv pov thawj cov cuab yeej, thiab lwm yam. Nws yog vim lawv cov substrate thiab active khoom. Nws ua rau LEDs pob tshab, muaj nyob rau ntawm tus nqi qis, kho qhov hluav taws xob, thiab txo lub teeb tso zis hluav taws xob kom zoo rau kev siv.

Cov lus qhia dav dav no yuav coj koj los ntawm cov khoom siv, sib piv cov txiaj ntsig, thiab piav qhia yuav ua li cas xaiv LED nti zoo.

Cov khoom siv tseem ceeb siv hauv UV LEDs

Cov ntaub ntawv tseem ceeb siv rau kev tsim cov ultraviolet LED nti yog muab faib ua substrates thiab cov khoom siv. Peb cov ntaub ntawv tseem ceeb hauv qab no yog siv los tsim cov chips.

1  Aluminium Nitride

Cov khoom siv tseem ceeb no siv UWBG lossis Ultra-Wide Bandgap Technology. Cov khoom sib sib zog nqus no tawm lub teeb nyob rau hauv ultraviolet ntau yam, thiab cov ntaub ntawv xws li gallium nitride thiab silicon carbide yog siv nrog rau nws kom ua kom lub zog ua haujlwm tau zoo.

Cov khoom no ua haujlwm ntawm lub wavelength hauv qab 315nm. Aluminium Nitride chips pab nrog kev ua haujlwm zoo thermal thiab txhim kho cov khoom siv hluav taws xob hauv LED. AIN lossis txhuas nitride hloov BeO lossis beryllium oxide vim nws tsis muaj kev phom sij rau kev noj qab haus huv. Nws tuaj yeem sawv qhov kub thiab txias thiab seamless rau kev siv hluav taws xob thiab lwm yam khoom siv.

2  AlGaN alloys

Cov hlau no yog kev sib xyaw ntawm Aluminium, Gallium, thiab Nitrogen, muab lub wavelength txog li 400nm. Qhov no alloy siv rau UV LED chips feem ntau siv cov UV-A module  Cov khoom siv sib xyaw ua ke no muaj qhov dav dav dav dav uas tso tawm lub teeb ultraviolet, ua rau nws haum rau cov khoom siv kho mob, sensors, huab cua thiab Tsis dej , sterilization, thiab lwm yam. Nws kuj pab txhim kho kev ua haujlwm ntawm cov khoom siv.

Vim lub physico-chemical zog ntawm AIGaN, cov kev kawm tseem ceeb tau ua tiav hauv optimizing chip manufacturing. Nws yog cov khoom siv zoo uas txhim kho kev ua haujlwm ntawm UV LED li. Lawv txawm siv los tsim eco-phooj ywg, ntse, thiab ruaj khov chips.

3  Substrate

Cov khoom tseem ceeb no yog cov chips’ lub hauv paus, lub zog, thiab kev txhawb nqa. Qhov tseem ceeb tshaj plaws substrate siv rau UV LEDs yog Sapphire. Nws yog pob tshab, muaj qhov dav dav, thiab muaj nyob ntawm tus nqi qis. Sib nrug los ntawm cov yam ntxwv no, Sapphire substrate muaj ntau lwm yam zoo, xws li nws cov khoom zoo, cov khoom siv tau zoo, nws muaj peev xwm tiv taus qhov kub thiab txias, yooj yim ntawm kev tu, thiab muaj zog txhua yam.

Tsis tas li ntawd, Saphire substrate nyob rau hauv cov chips ua tau raws li qhov xav tau ntawm kev lag luam curing. Cov yam ntxwv kev nyab xeeb thiab txuag hluav taws xob ua rau lub substrate no yog qhov zoo tshaj plaws rau kev siv LED. Zoo wavelength kis tau tus mob pab dav nrog cov khoom siv hluav taws xob tsim nyog thiab kev sib kis ntawm lub teeb thoob plaws hauv lub nti.

Kev sib piv ceev ntawm txhua cov ntaub ntawv tseem ceeb

Peb cov ntaub ntawv no muaj ntau yam zoo thaum siv hauv UV chips. Kev lag luam, cov tsev kho mob kho mob, cov neeg nyob hauv, chaw ua haujlwm, thiab lwm yam, tuaj yeem siv cov cuab yeej ua los ntawm cov ntaub ntawv tseem ceeb no thiab khaws cov txiaj ntsig ntau yam.

Yuav Ua Li Cas Xaiv Lub UV LED Chip rau Koj Daim Ntawv Thov?

·  Qhias:  Thaum xaiv ib qho UV LED, xyuas kom meej tias nws ua tau zoo los ntawm kev tso tawm ultraviolet wavelength haum rau cov haujlwm tshwj xeeb.
