LED teeb ua li cas?

Lub ntsiab tseem ceeb ntawm lub zog txuag hluav taws xob rau lub sijhawm ntev yog LED teeb pom kev zoo. LEDs tau tswj hwm kev lag luam, muab qhov ci ntsa iab thiab ruaj khov dua rau cov khoom siv hluav taws xob los yog cov fluorescent qhov muag teev nyob rau hauv txhua yam ntawm cov teeb liab tsheb mus rau lub teeb pom kev hauv tsev, xws liT8 LED tube teeb,qab nthab teeb,taug qab teeb. Tab sis ob peb tus neeg tau paub txog lawv txoj kev tsim khoom. Peb yuav tshuaj xyuas cov txiaj ntsig ntawm LED teeb pom kev zoo hauv daim ntawv no.

Cia peb xub qhia meej tias lub teeb LED yog dab tsi. Thaum ib tug tam sim no ntws los ntawm ib tug LED (Lub teeb Emitting Diode), ib tug semiconductor lub teeb qhov chaw, lub teeb yog tsim. Nyob rau hauv sib piv rau lub teeb fluorescent, uas siv cov tshuaj tiv thaiv los tsimLED tube teeb, thiab incandescent qhov muag teev, uas ua kom sov ib qho filament, LED teeb siv cov txheej txheem hluav taws xob uas tshwm sim hauv lub diode kom tawm lub teeb photons.

Xaiv cov ntaub ntawv zoo yog thawj kauj ruam hauv kev tsimT8 LED teeb. Peb cov khoom tseem ceeb yog ua ke los ua lub teeb ci LED: ib qho semiconductor, ib qho kev xav, thiab lub lens. Lub semiconductor nti, los yog wafer, uas ua rau feem ntau ntawm LED teeb yog tsim los ntawm cov ntaub ntawv xws li gallium arsenide, gallium nitride, los yog indium gallium nitride. Cov tshuaj no raug xaiv vim lawv lub peev xwm los tsim lub teeb thiab nqa hluav taws xob zoo.

Txoj kev loj hlob ntawm tus qauv wafer yog theem tom ntej hauv kev tsim khoom ntawmzoo LED tube teeb. Nyob rau hauv cov txheej txheem no, ib txoj kev photolithography yog siv los etch lub wafer. Ib txheej ntawm photoresist yog siv rau lub wafer nto thaum nws nyob hauv chav huv si. Tom ntej no, lub photomask yog siv los ua ib qho qauv rau ntawm qhov chaw photoresist. Tom qab ntawd, wafer raug kho los tsim cov qauv tsim nyog thiab raug UV teeb.

Lub wafer raug muab cais ua nyias nyias ib zaug nws tau engraved. Cov txheej txheem no, hu ua wafer dicing, ua rau siv lub tshuab uas siv lub pob zeb diamond pom los txiav cov wafer rau hauv me me. Tom qab ntawd, txhua lub nti yog fastened mus rau ib tug txhuas ncej, uas yog tsim los ntawm ib tug hluav taws xob conductive hlau.

Tom qab ntawd, cov txheej txheem kev sib txuas yog siv los muab cov nti rau ntawm cov hlau lead. Nyob rau hauv cov txheej txheem no, ib tug hlau los yog conductive adhesive yog siv los txuas lub nti mus rau cov hlau lead ncej. Cov hlau lead yog fastened rau lub substrate, uas yog tsim los ntawm ib yam khoom xws li yas los yog ceramic, thaum lub nti tau ntsia.

Lub zog efficiency ntawm LED teeb yog ib qho ntawm lawv cov txiaj ntsig tseem ceeb. Piv nrog rau hom teeb ci dhau los,LED tube teebsiv lub zog tsawg heev los tsim kom muaj qhov sib npaug ntawm lub teeb. Lub luminous efficiency, los yog ntau npaum li cas ntawm lub teeb tsim ib chav tsev ntawm hluav taws xob siv, yog siab dua rau LED teeb. Vim tias cov teeb ci LED tuaj yeem txo qis kev siv hluav taws xob thiab cov nqi hluav taws xob, lawv qhov kawg yuav raug nqi ntau dua.

Lub neej ntev ntawm LED teeb muab ib qho txiaj ntsig ntxiv. LED teeb muaj lub neej ntev dua li cov qij ib txwm siv-txog 25, 000 teev. Yog li ntawd, lawv xav tau kev saib xyuas tsawg dua thiab hloov tsis tu ncua, uas txo qis qhov cuam tshuam ib puag ncig ntawm kev hloov pauv cov qij qub.
