LED teeb, thiab yuav ua li cas rau lawv lub zog

Vim tias lawv cov kev siv hluav taws xob tsawg, kev ua neej ntev, thiab lwm yam txiaj ntsig, LEDs tau siv ntau dua li cov khoom siv hluav taws xob nyiam. Lawv xav tau AC-DC lub zog hluav taws xob, tsis zoo li cov luminaires incandescent, uas tuaj yeem txuas ncaj qha mus rau AC mains.Cov kab lus no tshuaj xyuas cov hloov pauv kom coj mus rau hauv tus account thaum xaiv cov khoom siv hluav taws xob haum rau LED teeb pom kev zoo.

Kev lag luam LED teeb pom kev lag luam thoob ntiaj teb tau cia siab tias yuav ncav cuag $ 127.04 billion los ntawm 2027 *, loj hlob ntawm CAGR ntawm 13.4 feem pua ​​​​nyob rau lub sijhawm kwv yees 2020-2027, raws li kev tshuaj xyuas tshiab los ntawm Grand View Research Inc.

Qhov kev loj hlob ntawm qhov nrov ntawm LEDs yog qhov tshwm sim ntawm ntau yam zoo. Lawv qhov kev ua tau zoo ntawm hluav taws xob zoo tshaj plaws thiab kev tu ncua ntev / hloov pauv yog tej zaum lawv cov yam ntxwv zoo tshaj plaws thiab paub zoo. Qhov no qhia tau hais tias lawv muaj tus nqi qis dua ntawm cov tswv cuab thiab cov pa roj carbon tsawg dua li cov khoom siv hluav taws xob. Qhov no yog qhov tseeb tshwj xeeb hauv cov tsev loj nrog cov qab nthab siab, qhov twg cov nuj nqis ntawm kev ua haujlwm yuav tsum tau hloov lub luminaires nrog rau cov luminaires lawv tus kheej yog qhov tseem ceeb.

Lawv kuj tseem txaus siab vim lawv qhov kev sib raug zoo nrog IoT-style teeb pom kev zoo. Lub ci ci thiab xim ntawm LEDs tuaj yeem hloov kho sai sai ntawm kev thov. Tsis zoo li incandescent hluav taws xob, uas yog omnidirectional thiab xav tau cov reflectors coj, lawv lub teeb tso zis yuav raug coj raws li xav tau.

Txawm li cas los xij, txhua tus tsim qauv thiab cov teeb pom kev zoo yuav tsum coj mus rau hauv tus account ib qho tseem ceeb ntawm cov cuab yeej siv hluav taws xob LED. Lub teeb-emitting diodes, lossis LEDs, yog cov khoom siv semiconductor xws li transistors lossis lwm hom diode, tab sis lawv kuj muaj peev xwm hloov hluav taws xob rau hauv lub teeb. Lawv tsis tuaj yeem txuas ncaj qha rau hauv AC qhov chaw tseem ceeb, tsis zoo li lub teeb pom kev zoo, vim tias lawv khiav ntawm DC voltages tsawg.

Muaj LED luminaires muaj nrog bayonet lossis Edison Screw fittings uas zoo li cov qauv incandescent. Cov no yog cov khoom siv incandescent uas khiav tawm ntawm lub ntsiab thiab muaj lub neej ntev dua thiab siv lub zog tsawg dua. Txawm li cas los xij, vim tias txhua lub luminaire yuav tsum muaj nws tus kheej hauv AC-DC electronics, lawv tuaj yeem kim. Lawv kuj tsis tsim nyog rau daim ntawv thov IoT tab tom nrhiav rau kev tswj hwm zoo vim lawv qhov chaw nkag tsis tau sab nraud ntawm AC fais fab kev sib txuas uas txuas rau lawv.

qhov tsawg-voltage DC zoo

Cov teeb pom kev zoo ntawm cov teeb pom kev zoo tuaj yeem siv cov teeb ci LED lossis cov strips, piv txwv li, nrog cov khoom siv hluav taws xob ntawm 12VDC lossis 24VDC, thiab lub zog rau lawv nrog AC-DC fais fab mov lossis tsav tsheb uas tseem muaj kev tswj dimming. Ib qho kev tswj xyuas nyuaj, xws li DALI (Digital Addressable Lighting Interface) tus qauv, tuaj yeem suav nrog hauv qhov no. Cov neeg siv tam sim no muaj peev xwm xa cov teeb pom kev zoo tswj kev txiav txim ntawm lub network uas tuaj yeem hais rau ib lub teeb los yog ib qho kev sib sau ntawm lub teeb. Brightness teeb tsa thiab cov qauv fading tuaj yeem kho tau.

Tsis tas li ntawd, cov xwm txheej tuaj yeem tsim tau, qhov twg ib qho kev tshaj tawm xov xwm ib zaug tig rau ntawm ntau lub teeb ntawm qib uas tau txiav txim siab. Piv txwv li, nyob rau hauv ib qho kev ua yeeb yam, tej zaum yuav muaj kev teeb tsa rau lub teeb muaj zog saum toj ntawm theem thiab teeb pom kev dim saum cov neeg tuaj saib.

Lub luag haujlwm tseem ceeb ntawm LED lub teeb hluav taws xob yog los txhais cov theem ntawm cov teeb liab tswj mus rau qib sib xws rau cov teeb pom kev zoo rau kev tsav tsheb LED (lossis LEDs), tsis hais seb qhov kev tswj cov tswv yim zoo li cas. Tus nqi tam sim no dhau los ntawm LED txiav txim siab nws qhov ci, uas feem ntau tswj hwm ntawm pulse width modulation (PWM). PWM lub voj voog ua haujlwm tau hloov pauv txhawm rau hloov kho LED qhov siab tshaj plaws tam sim no hauv mA. Nws tuaj yeem pom tau tias ko taw lambert (fL) lub teeb tso zis ntawm LED yog linearly ntsig txog lub luag haujlwm no.

Txawm li cas los xij, koj muaj lwm txoj kev xaiv thaum tab tom nrhiav rau qhov sib xws LED fais fab mov ntawm lub chaw tsim khoom lub vev xaib: tsis tu ncua-voltage vs. tas li-tam sim no hom. Lub ntsiab lus ntawm ntau hom thiab yuav ua li cas xaiv ntawm lawv tau piav qhia hauv cov tshooj hauv qab no.

Cov khoom siv hluav taws xob teeb pom kev zoo uas siv qhov tsis tu ncua-voltage piv rau qhov tsis tu ncua-tam sim no

Raws li yav dhau los tsim, LEDS yog cov khoom siv hluav taws xob semiconductor thiab tsis pom cov kab hluav taws xob rau pem hauv ntej / tam sim no tus yam ntxwv. Tam sim no ntws tau ntau ntxiv los ntawm kev nce me ntsis hauv pem hauv ntej voltage. Qhov no qhia tau tias muaj kev pheej hmoo ntawm kev tsav tsheb dhau ntawm LED tshwj tsis yog qee yam kev txwv tam sim no ua haujlwm. Ntau qhov tam sim no tuaj yeem ntws tau vim tias qhov nce tam sim no ua kom sov rau LED kev sib txuas. Qhov no yuav ua rau lub voj voog thermal khiav, uas tuaj yeem ua rau lub neej luv luv thiab ua rau nws ua tsis tiav.

Kev tsim kho ntawm LED cov rooj sib txoos, uas suav nrog ntau lub LEDs txuas nrog hauv cov kab nrog tam sim no-txheej resistor, yog ib txoj hauv kev lag luam rau qhov no. Tus nqi resistor hauv ohms tuaj yeem hloov kho thaum siv nrog lub zog hluav taws xob uas muaj qhov tso tawm qhov hluav taws xob tas li, uas nyob twj ywm tsis hais txog ntawm qhov load, kom lav tias tam sim no tsis dhau qhov kev txwv ntawm LEDs.

Installers ntawm lub teeb pom kev zoo tej zaum yuav pom cov qauv no txaus siab vim nws adaptability. Yog tias cov khoom siv hluav taws xob muaj peev xwm txaus los tswj nws qhov kev tso tawm qhov hluav taws xob tas li thaum lub nra nce, cov khoom siv LED ntxiv tuaj yeem ua ke thaum ua kom lub teeb ci tsis tu ncua thoob plaws hauv pab pawg.

Tam sim no-txheej resistors 'inefficiency nyob rau hauv cov nqe lus ntawm hluav taws xob efficiency, uas ua rau lub hwj chim poob raws li cua sov, yog ib tug tseem ceeb disadvantage ntawm txoj kev no. Qhov no yog unacceptably kim thiab ib puag ncig kev puas tsuaj nyob rau hauv lub teeb ntawm qhov txuas mus ntxiv kom txo tau cov pa roj carbon hneev taw.

Cov khoom siv hluav taws xob tas li tam sim no tuaj yeem ua si hauv qhov xwm txheej no. Txij li thaum lub hwj chim mov lub inbuilt tswj Circuit Court tswj txhua qhov tsim nyog tam sim no txwv, raws li lub npe qhia, LEDs tuaj yeem txuas ncaj qha rau lawv yam tsis tas siv cov khoom siv hluav taws xob tsis zoo.

Muab hais tias lawv yuav tsum tau faib cov theem tam sim no thiab yog li dhau los ua qhov muag tsis pom, LEDs tsis tuaj yeem txuas mus rau qhov sib npaug mus rau lub zog tam sim no. Txhawm rau khiav ntawm tib qib qub ci ntsa iab, lawv txhua tus tuaj yeem txuas nrog hauv cov koob, raug rau cov khoom siv hluav taws xob muaj peev xwm txwv.
