Kab lus piav qhia cov thev naus laus zis tshiab, lossis hloov lub teeb pom kev zoo (LED) teeb. Nrhiav seb nws yog dab tsi. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov teeb no. Tus nqi ntawm LED teeb, nrog rau keeb kwm ntawm LED teeb pom kev zoo
Dab tsi yog qhov muag teev LED - LED?
Qhov no yog lub teeb pom kev zoo ib yam nrog ntau lub LEDs hauv nws, nrog rau cov khoom siv hluav taws xob ib nrab ntawm ib txheej thiab cov txheej txheem kho qhov muag.
LED los yog LED
Yog cov khoom siv hluav taws xob uas cuam tshuam cov hluav taws xob hluav taws xob rau hauv lub teeb. Qhov ntau ntawm cov teeb pom kev tawm yog nyob ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov semiconductor.
Kev siv Light Emitting Diode (LED) thev naus laus zis hauv kev lag luam teeb pom kev zoo yog qhov tshwm sim tshiab. Qhov no yog qhov tseem ceeb vim tias cov cuab yeej siv siab tsuas yog muaj nyob hauv xyoo tas los no. Muaj ob qhov chaw tseem ceeb uas cov thev naus laus zis no yuav cuam tshuam rau kev lag luam teeb pom kev zoo nyob rau kaum xyoo tom ntej:
- teeb pom kev zoo;
- teeb pom kev zoo
Nyeem kab lus ntawm qhov tseem ceeb ntawm cov teeb LED kom paub saib dab tsi thaum xaiv lub teeb LED.
Cov txiaj ntsig ntawm LED qhov muag teev - LED
- Tsawg zog siv zog piv rau cov teeb pom kev zoo. Lub teeb zoo li no xav tau 10 watts los teeb lub chav sib npaug rau 100 watt lub teeb ci.
- Tsis muaj hluav taws xob UV. Qhov tivthaiv ultraviolet ntawm lub teeb pom kev zoo tuaj yeem ua rau cov nqaij mos ntawm qhov muag.
- Tshav kub me me yog tsim los ntawm lub teeb, txo tus nqi tsim tsev cua txias.
- Lub teeb lub neej ntev heev, nrog cov tuam txhab LED feem ntau kwv yees 40,000-50,000 teev ntawm lub teeb lub neej. Yog tias koj siv nws txhua hnub rau 5 teev, tom qab ntawd lub neej kev pabcuam yuav qhuav hauv ntau dua 10 xyoo.
- Lawv yog tus phooj ywg ib puag ncig piv rau lub teeb txuag hluav taws xob uas muaj mercury.
- Qhov hnyav me me, poob siab.
- Instant warm-up hauv tsawg dua 1 sec.
Qhov tsis zoo ntawm LED teeb - LED, tshuaj xyuas
- Qhov tseem ceeb thiab qhov tsis zoo ntawm cov teeb no yog lawv tus nqi, nws kim dua li ob lub teeb roj teeb thiab txuag hluav taws xob. Saib tus nqi hauv qab no.
- Qee tus neeg yws tias LED teeb muaj lub teeb pom kev tsis zoo. Yog li ntawd, nws tsis tsim nyog siv lawv hauv cov teeb rau kev nyeem phau ntawv lossis lwm yam kev mob siab rau. Tab sis koj kuj yuav tsum coj mus rau hauv tus account qhov tseeb tias ntau tus neeg yuav yuav thiab siv cov qub version ntawm cov teeb. Tam sim no thev naus laus zis tau nce zuj zus txhua xyoo thiab lub teeb ntawm cov teeb coj tshiab tau dhau los ua qhov muaj txiaj ntsig zoo dua li ua ntej. Yuav ib lub teeb zoo li no los ntawm lub khw tshwj xeeb thiab pom rau koj tus kheej tias nws yog txoj kev daws teeb meem.
- Vim tias siv cov teeb pom kev lag luam loj heev, cov tuam txhab hluav taws xob thiab lub xeev raug kev txom nyem, tom qab tag nrho, nws yog lawv cov txiaj ntsig uas tau txais kev cawmdim. Yog li ntawd, lawv feem ntau nce lawv cov nqi hluav taws xob. Tab sis kuv tsis xav tias qhov no yog qhov laj thawj tso tseg cov teeb no. Tam sim no lawv yog qhov yooj yim, cov roj teeb tau hloov pauv txhua txhua 2-4 lub hlis, vim tias lawv feem ntau "ya tawm" vim qhov ua tsis tau zoo. Thiab lub txee tau raug mob 5-8 zaug ntau dua.
Qee qhov "pessimists" pom ob peb qhov laj thawj txaus kom tawm mus yav dhau los thiab tsis siv cov thev naus laus zis tshiab ntawm yav tom ntej. LED thev naus laus zis tsim lub teeb pom kev yav tom ntej, qhov twg muaj hluav taws xob tsawg dua ntawm cov xov hlau, txuag hluav taws xob, kev nyab xeeb thiab zoo. TutKnow.ru rau LED teeb!
Nqi rau qhov muag teev LED
Hauv tebchaws Russia, Tegas Fais Fab tau koom tes nrog tsim cov teeb LED thiab lwm yam khoom siv rau lawv. Tam sim no muaj ntau yam khoom lag luam, txawm hais tias nws yog cov teeb hauv lub teeb rau chav me lossis hauv qhov ntxoov ntxoo rau chaw ua haujlwm loj. Thiab tseem yog cov teeb roj teeb rau txoj kev teeb pom kev zoo.
Nqi
rau cov teeb zoo li no pib los ntawm 200 rubles txog 1000 lossis ntau dua. Tus nqi nyob ntawm cov yam ntxwv ntawm lub teeb. Sij hawm dhau mus, tus nqi rau cov khoom no yuav poob. Cov teeb ci LED yuav dhau los ua neeg nkag tau yooj yim dua.
Keeb kwm ntawm LED teeb pom kev zoo
Teeb pom kev zoo yuav tsum siv lub teeb dawb. LEDs tsis tuaj yeem tsim lub teeb dawb, lawv tsuas tuaj yeem tsim qee qhov xim hauv cov xim. Ib qho LED yog cov cuab yeej siv hluav taws xob uas tsim los ntawm kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob sib txawv. Cov tshuaj lom neeg muaj pes tsawg leeg xaiv los txiav txim siab lub zog ntawm cov hluav taws xob uas dhau los ntawm kev sib cuam tshuam ntawm ob hom semiconductors. Lub zog no tau hloov pauv mus rau hauv lub teeb raws li cov kwj ntawm cov hluav taws xob, txawm hais tias lub cuab yeej tau txiav txim siab los ntawm qhov nthwv dej ntawm qhov ua kom pom lub teeb.
Muaj ob txoj hauv kev tuaj yeem tsim lub teeb los ntawm LED. Thawj zaug tau siv thawj zaug hauv Nyij Pooj xyoo 1996: Lub xiav LED tau pleev xim nrog dawb phosphorus. Thaum lub teeb xiav tsoo sab hauv ntawm phosphor, nws tso tawm lub teeb dawb. Tam sim no thev naus laus zis tau raug txiav txim siab rau kev lag luam, tab sis tseem muaj qee qhov kev txhawj xeeb txog kev siv thev naus laus zis lub neej. Nws tau raug sau tseg tias phosphorus tuaj yeem txo qhov dej ntws zoo thoob plaws xyoo. Kev kwv yees lub neej tam sim no yog kwv yees li 6 xyoos.
Txoj hauv kev thib ob kom tau txais lub teeb dawb yog siv kev sib xyaw ntxiv ntawm peb qhov xim thawj: liab, ntsuab, thiab xiav.
Lub tswv yim ntawm kev sib xyaw LED teeb tso tawm thawj zaug tau ua tiav hauv xyoo 1979 los ntawm Sound Chamber cov neeg ua haujlwm. Cov khoom lag luam hu ua "Saturn" siv lub kiv cua tig. Txhua ntawm peb lub kiv cua tis tau tsim los ntawm cov phiajcim nruab nrog LEDs liab, ntsuab thiab daj. (Cov LED xiav tseem tsis tau tsim dua tshiab.) Txhua lub LEDs raug tswj los ntawm kev ntsuas dav dav (PWM), uas ua kom muaj zog ntawm txhua tus neeg LED nyob hauv kev tswj hwm. Cov khoom tuaj yeem tsim ntau yam xim loj loj.
Qhov txuas ntxiv tom ntej hauv thev naus laus zis tuaj xyoo 1993 nrog kev tsim lub teeb xiav LED, thiab thaum ntxov xyoo 1994, daim ntawv tso cai ua txuj ci tau tsim los rau yam uas tau txiav txim siab ua thawj xim sib xyaw siv liab, ntsuab thiab xiav LEDs. Kev tsim qauv siv lub tshuab ntsuas hluav taws xob rau txhua qhov xim, nrog Zilog Z8 microprocessor.
Lub zeem muag rau kev txhim kho ntawm LEDs
Hauv Belgium, LUMILED, kev sib koom ua ke ntawm Philips thiab Agilent, tab tom txhim kho rau qhov ua kom pom kev ci ci ntau dua. Hauv Nyij Pooj, Nichia tseem thawb kom ci ci - tus nqi rau nyiaj. Hauv tebchaws Askiv, Cambridge Display Technology tau ua tiav hauv kev tsim lub ntiaj teb thawj lub teeb ci emitting polymer (LEP) thiab tam sim no tau ploj mus rau kev tsim cov organic dawb lub teeb-emitting diodes (OLED). Tam sim no, txhua qhov kev txhim kho hauv cheeb tsam no tau hais rau kev tsim cov thev naus laus zis uas tuaj yeem siv rau hauv cov xim xim.
Hauv Asmeskas, Massachusetts Institute of Technology (Nano Structures Lab) tab tom ua haujlwm ntawm cov cuab yeej hu ua photonic band gap LED. Kev tshawb fawb thawj zaug tsom mus rau kev txhim kho kev ua haujlwm ntawm ib leeg xim LEDs. Kev txuas ntxiv rau qhov kev tshawb fawb no tuaj yeem ua rau LED qhov twg ob qho xim thiab siv tau tuaj yeem teeb tsa hluav taws xob. Lub peev xwm rau teeb pom kev zoo yog qhov xav tsis thoob. Qhov tseem ceeb tshaj plaws uas yog lub peev xwm los tsim kev daws teeb meem siab dua ntawm qhov qis dua. Nws yog qhov tshwj xeeb hauv kev sib xyaw xim.
