Cov txheej txheem ntau lawm ntawm cov teeb LED teeb

Cov txheej txheem tsim khoom ntawmCov hlaws teeb LEDyog ib qho tseem ceeb hauv kev lag luam teeb pom kev zoo LED. Cov hlaws teeb LED, tseem hu ua cov diodes teeb emitting, yog cov khoom tseem ceeb siv rau ntau yam kev siv xws li teeb pom kev zoo hauv tsev mus rau kev daws teeb meem teeb pom kev zoo hauv tsheb thiab kev lag luam. Nyob rau xyoo tas los no, vim muaj qhov zoo ntawm kev txuag hluav taws xob, lub neej ntev, thiab kev tiv thaiv ib puag ncig ntawm cov hlaws teeb LED, lawv qhov kev thov tau nce ntxiv, ua rau muaj kev nce qib thiab kev txhim kho ntawm cov thev naus laus zis tsim khoom.

Cov txheej txheem tsim cov hlaws teeb LED muaj ntau theem, txij li kev tsim cov khoom siv semiconductor mus rau qhov kawg sib dhos ntawm cov chips LED. Cov txheej txheem pib nrog kev xaiv cov khoom siv huv siab xws li gallium, arsenic, thiab phosphorus. Cov ntaub ntawv no tau muab sib xyaw ua ke hauv cov feem sib npaug kom tsim cov siv lead ua los ntawm semiconductor uas yog lub hauv paus ntawm LED technology.

Tom qab cov khoom siv semiconductor tau npaj tiav lawm, nws yuav dhau los ntawm cov txheej txheem ntxuav kom huv si kom tshem tawm cov khoom tsis huv thiab txhim kho nws cov kev ua tau zoo. Cov txheej txheem ntxuav no ua kom ntseeg tau tias cov hlaws teeb LED muab qhov ci ntsa iab dua, xim sib xws, thiab ua haujlwm tau zoo dua thaum siv. Tom qab ntxuav, cov khoom siv raug txiav ua cov wafers me me siv lub tshuab txiav siab heev.

Kauj ruam tom ntej hauv cov txheej txheem tsim khoom suav nrog kev tsim cov LED chips lawv tus kheej. Cov wafers raug kho kom zoo nrog cov tshuaj tshwj xeeb thiab dhau los ntawm cov txheej txheem hu ua epitaxy, uas cov txheej txheem ntawm cov khoom siv semiconductor raug tso rau ntawm qhov chaw ntawm wafer. Qhov kev tso nyiaj no yog ua tiav hauv ib puag ncig tswj hwm siv cov txheej txheem xws li hlau-organic tshuaj vapor deposition (MOCVD) lossis molecular beam epitaxy (MBE).

Tom qab ua tiav cov txheej txheem epitaxial, lub wafer yuav tsum tau dhau los ntawm ntau cov kauj ruam photolithography thiab etching los txhais cov qauv ntawm LED. Cov txheej txheem no cuam tshuam nrog kev siv cov txheej txheem photolithography siab heev los tsim cov qauv nyuaj ntawm qhov chaw ntawm wafer uas txhais cov khoom sib txawv ntawm cov chip LED, xws li thaj chaw p-hom thiab n-hom, cov khaubncaws sab nraud povtseg, thiab cov ntaub qhwv sib cuag.

Tom qab cov LED chips raug tsim tawm, lawv yuav dhau los ntawm kev txheeb xyuas thiab kuaj xyuas kom paub tseeb tias lawv zoo thiab ua tau zoo. Cov chips raug kuaj xyuas cov yam ntxwv hluav taws xob, qhov ci ntsa iab, qhov kub xim, thiab lwm yam kom ua tau raws li cov qauv tsim nyog. Cov chips tsis zoo raug txheeb xyuas thaum cov chips ua haujlwm mus rau theem tom ntej.

Nyob rau theem kawg ntawm kev tsim khoom, cov LED chips raug ntim rau hauv cov hlaws teeb LED kawg. Cov txheej txheem ntim khoom suav nrog kev teeb tsa cov chips rau ntawm tus ncej hlau, txuas lawv rau cov khoom siv hluav taws xob, thiab qhwv lawv hauv cov khoom siv resin tiv thaiv. Cov ntim khoom no tiv thaiv cov chips ntawm cov khoom ib puag ncig thiab ua rau nws ruaj khov dua.

Tom qab ntim khoom, cov hlaws teeb LED raug kuaj xyuas ntxiv txog kev ua haujlwm, kev ruaj khov, thiab kev ntseeg tau. Cov kev kuaj no ua piv txwv txog kev ua haujlwm tiag tiag kom ntseeg tau tias cov hlaws teeb LED ua haujlwm ruaj khov thiab tuaj yeem tiv taus ntau yam ib puag ncig xws li kev hloov pauv kub, av noo, thiab kev co.

Zuag qhia tag nrho, cov txheej txheem tsim cov teeb LED yog qhov nyuaj heev, xav tau cov tshuab siab heev, kev tswj hwm meej, thiab kev tshuaj xyuas zoo nruj. Kev nce qib hauv cov thev naus laus zis LED thiab kev ua kom zoo dua ntawm cov txheej txheem tsim khoom tau pab txhawb rau kev ua kom cov teeb pom kev zoo LED siv hluav taws xob ntau dua, ruaj khov, thiab txhim khu kev qha. Nrog kev tshawb fawb thiab kev txhim kho tas mus li hauv daim teb no, cov txheej txheem tsim khoom yuav raug txhim kho ntxiv, thiab cov teeb LED yuav ua haujlwm tau zoo dua thiab pheej yig dua yav tom ntej.

Yog tias koj xav paub txog cov txheej txheem tsim cov teeb LED, txais tos hu rau lub chaw tsim khoom teeb pom kev zoo LED TIANXIANG kom paub meej ntxiv.nyeem ntxiv.
