Hauv kev lag luam teeb pom kev lag luam niaj hnub, LED teeb vaj huam sib luag tau loj hlob hauv qhov chaw. Lawv tuaj yeem raug kho kom haum rau txhua lub hom phiaj thiab muaj lub zog txuag thiab hloov tau. Txawm li cas los xij, koj puas paub txog cov ntaub ntawv siv los ua cov teeb ci LED? Lub Cheebtsam ntawm LED teeb vaj huam sib luag thiab lawv cov haujlwm yuav tau tham hauv tsab xov xwm no.
Ib tug xov tooj ntawm qhov chaw ua ke los tsim LED teeb vaj huam sib luag, uas muab cov teeb pom kev zoo xav tau. Lub teeb-emitting diode (LED), tsav tsheb, lub dab dej kub, thiab diffuser yog qee qhov ntawm cov khoom no.
LED lub teeb vaj huam sib luag cov ntsiab lus tseem ceeb yog LED. Nws siv cov txheej txheem hu ua electroluminescence los tsim lub teeb. Lub teeb pom kev yog tsim los ntawm cov hluav taws xob zoo siab hauv cov khoom siv semiconductor ntawm LED thaum muab hluav taws xob tam sim no.
Ib qho hluav taws xob tivthaiv hu ua tus tsav tsheb LED tswj qhov zoo thiab muaj nuj nqis ntawm tam sim no uas dhau los ntawm LED. Tus neeg tsav tsheb hloov qhov voltage thiab tam sim no los ntawm lub zog hluav taws xob mus rau qhov tseeb qhov tseem ceeb uas LED xav tau. Tsis tas li ntawd, nws tiv thaiv tam sim no spikes thiab voltage variations uas yuav ua mob rau lub LED.
Ib qho tseem ceeb ntawm LED lub teeb vaj huam sib luag, lub dab dej kub pab hauv dissipating lub tshav kub uas tsim los ntawm LED. Thaum siv LEDs, lawv tsim cov cua sov, thiab yog tias lawv tau kub dhau, lawv lub neej thiab kev ua haujlwm yuav raug kev txom nyem. Lub dab dej kub ua kom lub neej ntev ntawm LED thiab ua kom nws txias.
Cov txheej txheej ntawm LED lub teeb vaj huam sib luag, lub npe hu ua lub diffuser, pab nyob rau hauv cov teeb pom kev zoo sib xws thiab txo qhov ci ntsa iab. Feem ntau, nws yog tsim los ntawm lub teeb yuag, siv tau ntev zoo li acrylic lossis polycarbonate. Tsis tas li ntawd, lub diffuser tuaj yeem hloov kho los muab ntau yam kev pom, xws li textured lossis frosted nto.
LED teeb vaj huam sib luag yog tsim los siv ntau yam khoom siv thiab cov khoom ntxiv rau cov no. Cov no yuav muaj xws li:
1. Printed Circuit Boards (PCBs): PCBs yog dab tsi txuas tus tsav tsheb mus rau LED chips. Lawv muab cov hluav taws xob raws ntawm qhov tam sim no yuav dhau los ntawm LED.
2. Cov Hlau thiab Cables: LED lub teeb vaj huam sib luag txuas nrog lub zog hluav taws xob los ntawm cov xov hlau thiab cables. Tsis tas li ntawd, lawv tau siv los koom nrog ntau lub teeb ci LED.
3. Housings: Sab hauv ntawm LED teeb vaj huam sib luag yog shielded los ntawm vaj tse. Feem ntau yog tsim los ntawm cov yas lossis hlau, lawv tuaj yeem hloov kho kom haum rau qhov xav tau.
4. Adhesives: Qhov sib txawv ntawm LED teeb vaj huam sib luag tau koom ua ke siv cov nplaum nplaum. Qhov kub thiab txias, av noo, thiab lwm yam ib puag ncig yuav tsum tsis txhob ua phem rau lawv.
Cia peb tshuaj xyuas LED lub teeb vaj huam sib luag 'kev ua haujlwm hauv kev nthuav dav ntxiv tam sim no peb paub tias lawv muaj li cas. Cov hluav taws xob hluav taws xob tau hloov mus rau hauv lub teeb lub zog los ntawm LED lub teeb vaj huam sib luag. Cov hluav taws xob txav mus los ntawm cov khoom siv ntawm LED thaum muaj qhov tam sim no, thiab photons raug tso tawm, ua kom pom lub teeb.
Cov khoom siv semiconductor siv los txiav txim siab cov xim ntawm lub teeb uas LED tsim. Cov xim sib txawv, suav nrog liab, ntsuab, thiab xiav, yog tsim los ntawm cov khoom sib txawv. Tag nrho cov xim tuaj yeem tsim los ntawm kev sib xyaw cov xim no.
Piv nrog rau cov teeb pom kev zoo ib yam li cov qij incandescent, LED lub teeb vaj huam sib luag muaj zog heev thiab siv hluav taws xob tsawg dua. Tsis tas li ntawd, lawv lub neej ntev dua-txog 50, 000 teev lossis ntau dua-uas txo qis qhov xav tau hloov pauv thiab tu.
LED lub teeb vaj huam sib luag yog qhov hloov tau zoo heev ntxiv rau qhov ua tau ntev thiab siv zog. Lawv tuaj yeem siv rau ntau lub hom phiaj, suav nrog kev teeb pom kev zoo rau lub tsev thiab kev lag luam, tsheb, thiab txawm tias horticulture, uas suav nrog cov nroj tsuag loj hlob hauv.
Txhawm rau ua kom tiav, LED lub teeb vaj huam sib luag yog tsim los ntawm ntau qhov chaw tseem ceeb uas koom tes los muab cov teeb pom kev zoo. Cov khoom no muaj xws li diffuser, lub dab dej kub, tus tsav tsheb, thiab lub teeb-emitting diode. Cov ntawv luam tawm Circuit Court boards, xov hlau thiab cables, vaj tse, thiab cov nplaum yog lwm yam khoom siv hauv kev tsim cov teeb ci LED.
Electroluminescence yog txoj kev uas LED lub teeb vaj huam sib luag hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog. Lawv yog ib qho kev xaiv zoo rau kev siv teeb pom kev zoo hauv tsev, kev lag luam, tsheb, thiab horticulture vim lawv muaj txiaj ntsig zoo, siv lub zog tsawg dua li cov teeb pom kev zoo, thiab kav ntev dua. LED lub teeb vaj huam sib luag yog lub teeb pom kev ntawm lub neej yav tom ntej vim nws lub neej ntev, kev siv hluav taws xob, thiab kev hloov pauv.
