Txij li thaum cov tsos ntawm thawj LEDs, lawv tau nquag siv nyob rau hauv ntau yam ntawm tib neeg lub neej. Cov no yog cov teeb nyem, teeb pom kev zoo hauv tsev, thiab, tau kawg, cov ntxaij vab tshaus TV thiab ntau yam khoom siv uas muaj qhov screen lossis thaj chaw tso saib. Kab lus no yuav tsom mus rau SMD 5630 LED.
keeb kwm me ntsis
Emissions los ntawm lub xeev cov khoom diode tau pom thawj zaug hauv xyoo 1907 los ntawm Henry Round. Nws pom tias electroluminescence tau pom thaum tam sim no dhau los ntawm cov hlau thiab silicon carbide. Thiab tom qab ntawd tus kws tshawb fawb Lavxias Losev pom cov xwm txheej zoo sib xws. Nws txawm luam tawm nws qhov kev tshawb pom, txawm li cas los xij, vim qhov tseeb tias kev tshawb fawb ntawm lub sijhawm ntawd tsis tso cai rau kev piav qhia tag nrho ntawm qhov tshwm sim, nws tseem tsis tau pom dua. Losev muaj peev xwm txaus siab rau qhov tseem ceeb ntawm nws qhov kev tshawb pom, uas ua rau nws muaj peev xwm tsim cov khoom me me hauv lub xeev (tsis yog lub tshuab nqus tsev) lub teeb pom kev zoo nrog cov khoom siv hluav taws xob tsawg heev thiab tsis muaj peev xwm rau kev ceev. Nws tau txais ob daim ntawv pov thawj kev cai lij choj rau Lub Teeb Relay. Xyoo 1961, Robert Byard thiab Gary Pittman ntawm Texas Instruments nrhiav tau thiab patented infrared LED technology.
Kev txhim khoThawj lub diode ua haujlwm tau tsim los ntawm Nick Holonyak ntawm University of Illinois. Nws LED ua haujlwm hauv qhov xim liab.
Rau lub sijhawm ntev, LEDs tau kim heev los tsim khoom. Lawv tus nqi nruab nrab yog kwv yees li $ 200, uas cuam tshuam rau qhov ntau. Cov neeg Nyij Pooj tau tswj kom tau txais ib qho pheej yig LED nyob rau thaum ntxov nineties. Txij thaum ntawd los, LED tau pom nyob rau hauv yuav luag txhua lub cuab yeej hauv ntiaj teb.
Tus nqi ntawm LED yog dab tsi?
LEDs tau siv dav hauv kev lag luam thiab lub neej txhua hnub rau ntau tus yam ntxwv muaj txiaj ntsig:
- siab luminous efficiency - nyob rau hauv cov nqe lus ntawm tus nqi ntawm lub teeb tau txais los ntawm ib watt, lub LED yog nyob rau hauv ntau txoj kev superior rau txheem teeb;
- lub zog siab thiab kev co zoo thiab kev co siab ntev;
- durability;
- loj spectrum ntawm emitted tshav kub ntawm lub teeb;
- nqi qis;
- tsis muaj qhov hluav taws xob siab, uas txhais tau tias qis dua qhov pib rau cov kws tshaj lij thiab cov neeg tsim khoom;
- ua siab ntev rau qis thiab qis qis;
- sustainable.
Qhov no tau lees paub los ntawm cov neeg siv tshuaj xyuas.
LED txoj cai ua haujlwm
Kev ua haujlwm ntawm ib qho LED yog nyob ntawm electron-qhov conductivity. Hauv kev xyaum, qhov no txhais tau hais tias lub caij muaj ob qhov sib txawv semiconductors nrog cov qib sib txawv ntawm cov conductivity. Ib tug ntawm lawv yog qhov zoo, lwm qhov yog qhov tsis zoo. Ntawd yog, qhov thiab electron, feem. Thaum lub sij hawm ib tug hluav taws xob tam sim no dhau los ntawm LED, nyob rau hauv lub point ntawm kev sib cuag ntawm obsemiconductors, kev hloov ntawm electrons mus rau qhov dawb tshwm sim. Tib lub sijhawm, lub zog raug tso tawm, uas qhia los ntawm lub ci.
YLED SMD 5630
Tus tsim ntawm lub caij yog lub vaj huam sib luag nrog qhov ntev ntawm 5 hli los ntawm 3 hli los ntawm 0.8 hli. Cov ntaub ntawv no yog ua los ntawm cov yas uas tsis muaj cua sov, nyob rau hauv uas muaj ib tug muaj zog siv lead ua. SMD 5630 muaj 4 tus pins. Txawm li cas los xij, tsuas yog 2 tau koom nrog hauv txhua qhov kev qhia tshwj xeeb, nws yog kev cai los xaiv tus anode nrog tus lej 4, thiab cov cathode nrog tus lej 2. Ib qho tshwj xeeb uas ua rau lub substrate yog muab tso rau sab nraub qaum.
Parameters
Cov yam ntxwv ntawm SMD 5630 feem ntau nyob ntawm cov chaw tsim khoom tshwj xeeb. Tab sis yuav luag tag nrho cov ntawm lawv raug rau cov qauv sib xws thiab tsim cov ntsiab lus nyob rau hauv kev txwv. Qhov no txhais tau hais tias lub zog tuaj yeem nyob ntawm ciam teb ntawm 0.5 txog 1.1 watts. Qhov voltage ntau ntawm 3 mus rau 3.8 volts. Kev khiav hauj lwm thiab mem tes tam sim no yog 150 thiab 400 milliamps, feem. Kev lees paub lub neej feem ntau yog 30,000 teev.
Sib piv ntawm SMD 5630 nrog lub teeb pom kev zoo tib yam thiab cov analogues ze tshaj
Hais txog cov teeb pom kev zoo ib yam, txhua qhov LED yeej rau qhov loj. SMD 5630 lub zog pib ntawm 0.5W. Lub teeb zoo tib yam, raws li txoj cai, yog los ntawm 65 thiab siab dua. Lub ci ci ntawm lub caij, txawm hais tias qis dua hauv cov ntsiab lus txheeb ze thiab tsuas yog 57 lumens, tuaj yeem hla tus neeg sib tw yog tias peb txhais tag nrho cov no rau hauv lub zog ib 'meter'. SMD 5630 qhia 0.34 lumens ib sq. seej, aQhov muag teev - 0.031 lumens ib sq. saib Raws li rau lub sijhawm ntawm kev pabcuam, ntawm no LED pom tau zoo ua tus coj. Yog tias lub teeb pom kev zoo tsim los ua haujlwm rau 1000 teev, SMD 5630 boasts 30,000 teev. Nyob rau tib lub sijhawm, cov nqi hluav taws xob tsawg dua. Qhov no yog vim qhov khoom siv hluav taws xob ntawm ob lub ntsiab lus. Lub teeb qhov muag xav tau txog 200 volts, thaum LEDs tsuas xav tau li 3.
Cov neeg sib tw ze tshaj plaws ntawm SMD 5630 yog 3528, 5050, 5730. Nws yog ib qho tsim nyog sau cia tias cov cim ntawm cov LEDs sib haum rau lawv qhov loj. Piv txwv li, SMD 3528 muaj qhov loj ntawm 35 x 28 mm. A 5050 - 50 x 50 mm.
Ntawm tag nrho cov npe teev, tsuas yog SMD 3528 sawv tawm nrog nws lub zog kom deb li deb. Nws pib los ntawm 0.11 watts. Nyob rau hauv cov nqe lus ntawm brightness, 5730 coj ntawm tag nrho cov ntsiab nrog nws 60 lumens. Lub kaum sab xis saib ntawm yuav luag txhua LEDs yog tib yam thiab yog 120 degrees. Lub sijhawm ua haujlwm kuj tsis hloov pauv ntau thiab qhov nruab nrab qhia los ntawm tus lej ntawm 30,000 teev. Nyob rau hauv cov nqe lus ntawm brightness, nyob rau hauv cov nqe lus ntawm lumens ib watt, ntawm tag nrho cov qhia LEDs, lub 5730 yeej nrog ib tug nqi ntawm 120. Lub SMD 5630 muaj 114.
Scope of application
Vim tias SMD 5630 LED muaj kev ua tau zoo tshwj xeeb, nws daim ntawv thov ntau heev. Nws yog siv nyob rau hauv tapes los muab illumination ntawm ntau yam pab kiag li lawm thiab pab kiag li lawm. Tsheb, khw qhov rais, nrog rau sab hauv ntawm thaj chaw nyob. Qee zaum, kev siv zog zoo tso cai rau koj siv cov yam ntxwv ntawm SMD 5630 LEDs hauv kev teeb pom kev zoo.
Cov qauv thiab tsim cov ntsiab lus ua rau nws tuaj yeem txuas rau ntawm lub rooj tsav xwm luam tawm. Thaum nws tus kheej soldering, nws raug nquahu kom tsis txhob tshaj qhov kub ntawm cov hlau soldering ntau tshaj 200 degrees. Koj kuj yuav tsum tsis txhob ncua ntev kov lub caij nrog nws.
Cov yam ntxwv ntawm SMD 5630 LEDs tso cai rau nws siv yuav luag txhua qhov chaw. Txhawm rau teeb pom kev loj ntawm qhov chaw, ib txheej ntawm ob peb lub ntsiab lus los yog hu ua tus kav yog siv. Ua piv txwv, SMD 5630 72 LED kab. Nws yog ib lub vaj huam sib luag me me nrog 72 lub ntsiab lus tso rau ntawm nws. Los ntawm kev sib sau ua ke thiab txhim kho lawv hauv thaj chaw uas xav tau, koj tuaj yeem ua tiav lub teeb pom kev zoo ntawm thaj chaw loj ntawm sab nrauv.
Cov teeb pom kev zoo rau cov teeb pom kev hauv tsev tau maj mam pib tawm hauv kev ua lag luam, hauv lawv qhov chaw tuaj LED, muaj txiaj ntsig zoo dua ntawm cov yam ntxwv ntawm kev ua haujlwm. Lub teeb 100 watt tuaj yeem hloov tau yooj yim los ntawm LED counterpart nrog lub zog ntawm 11 xwb. Thiab qhov no yog qhov tseem ceeb ntawm kev txuag hluav taws xob.
Lub teeb LED rau lub teeb pom kev hauv tsev feem ntau muaj ob peb LEDs. Ua ke, lawv tsim teeb ci ntau dua li cov teeb pom kev zoo.
LED strips raws li SMD 5630 kuj tseem siv los ua cov khoom zoo nkauj hauv cov teeb pom kev zoo sab hauv. Yog hais tias chav tsev yog txawm peem rau nrog cov hniav niches, ntau yam eye-catching ntsiab, ces accentuating lawv nrog LED teeb yuav muab lub chav elegance thiab ib tug tshwj xeeb style. LED strips muaj ntau yamLEDs uas tau muab tso nrog ib kauj ruam. Qhov no tso cai rau lub teeb kom tawg, uas muab cov nyhuv ntawm tag nrho cov illumination. Xws li daim kab xev yog mounted, raws li txoj cai, los ntawm ib tug tshwj xeeb adapter, uas muaj peev xwm muab tag nrho cov teeb ntawm LEDs nrog lub zog tsim nyog thiab ruaj khov voltage nrog ib tug margin.
Zoo kawg
LEDs tau muaj kev cuam tshuam loj rau yuav luag txhua yam kev lag luam. Nws tau dhau los ua kom tsim tau cov khoom siv teeb pom kev zoo. Thiab qhov no, nyob rau hauv lem, coj mus rau ib tug txo nyob rau hauv tus nqi ntawm cov pa phem thiab emissions rau hauv ib puag ncig. Lub compactness thiab yooj yim ntawm kev ua hauj lwm nrog LEDs tau nyiam ntau tus kws tshaj lij hauv daim teb no. Yuav luag txhua leej txhua tus tuaj yeem tswj hwm qhov kev sib txuas ntawm cov khoom npaj npaj ua LED rau lub adapter, thiab tom qab ntawd mus rau lub mains.
Kev siv LED backlighting hauv cov khoom siv high-tech kuj tsis mus unnoticed. Cov TV niaj hnub pib muab cov duab ci ntsa iab. Smartphones tau txais lub zog txuag hluav taws xob rau lawv cov ntxaij vab tshaus. Ntau yam kev qhia txog cov cuab yeej siv LEDs tau dhau los ua qhov me thiab kev lag luam ntau dua.
