LEDs yog dab tsi?
Lus Askiv ntawm LED - lub teeb emitting diode literally translates to light emitting diode. Lub teeb-emitting diode yog ib qho semiconductor uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog. Nws cov qauv yooj yim yog tso lub electroluminescent semiconductor wafer rau ntawm lub txee coj, thiab ib puag ncig yog kaw nrog epoxy resin. Lub hauv paus ntawm lub teeb-emitting diode yog wafer muaj xws li P-hom semiconductors thiab N-hom semiconductors, nrog rau kev hloov txheej ntawm ob lub semiconductors, hu ua "PN junction". Hauv qee qhov PN junctions, thaum cov neeg nqa khoom tsawg thiab cov neeg nqa khoom feem ntau rov ua dua, lub zog ntau dhau yuav raug tso tawm hauv lub teeb, yog li hloov hluav taws xob rau hauv lub teeb lub zog. Qhov no yog lub teeb-emitting txoj cai ntawm LEDs. Txawm li cas los xij, yog tias qhov hluav taws xob rov qab nkag mus rau PN kev sib tshuam, nws yuav nyuaj rau cov neeg nqa khoom tsawg los txhaj, thiab nws yuav tsis tuaj yeem tawm lub teeb rau lub sijhawm no. Hom diode no ua los ntawm lub hauv paus ntsiab lus ntawm kev txhaj tshuaj electroluminescence yog hu ua lub teeb-emitting diode, lossis LED.
LED teeb peb pom feem ntau tuaj ntawm ntau yam xim, nyob ntawm seb cov khoom uas ua rau PN kev sib tshuam. Thaum lub LED nyob rau hauv ib tug pem hauv ntej ua hauj lwm lub xeev, uas yog, ib tug pem hauv ntej voltage yog input nyob rau hauv lub semiconductor thiab tam sim no ntws los ntawm lub anode mus rau lub cathode ntawm lub LED, lub semiconductor siv lead ua yuav emission txawv xim ntawm lub teeb vim cov khoom sib txawv. Piv txwv li, magnesium arsenide diodes emit liab teeb, magnesium phosphide diodes emit ntsuab teeb, silicon carbide diodes emit daj lub teeb, thiab magnesium nitride diodes emit xiav lub teeb... Qhov kev siv ntawm lub teeb yuav hloov thaum lub tam sim no txawv.
Piv nrog rau lwm yam teeb pom kev zoo, LED semiconductor lub teeb qhov chaw hu ua "ntsuab lub teeb qhov chaw" thiab muaj ntau yam zoo uas nyuaj los hloov: siab luminous efficiency, luminous efficiency yuav ncav cuag 50 mus rau 200 lumens / watt; tsawg zog noj, tib lub teeb pom kev zoo, LED Lub zog noj ntawm lub teeb yog ib feem yim ntawm lub teeb incandescent thiab ib nrab ntawm lub teeb fluorescent; lub neej ua haujlwm ntev, thiab qhov nruab nrab tuaj yeem siv tau 100,000 teev; qhov ci ntsa iab thiab xim yog qhov yooj yim los tswj, thiab cov xim hloov pauv hloov pauv thiab digital tswj tuaj yeem pom tau, thiab qhov ci tuaj yeem hloov kho tsis tu ncua. Nws tsis muaj cov tshuaj phem xws li mercury thiab sodium, thiab cov khoom pov tseg tuaj yeem rov ua dua tshiab, uas yog ib puag ncig zoo. Tsis tas li ntawd, LED semiconductor lub teeb ci tseem muaj cov yam ntxwv ntawm qhov me me, kev ntseeg siab, lub sij hawm teb luv luv thiab cov qauv yooj yim, uas yog qhov tsim nyog rau cov teeb pom kev zoo hauv nroog.
Txawm li cas los xij, qee qhov teeb meem ntawm LED teeb kuj tseem pom tseeb dua, uas yog, nws yuav ua rau qee qhov kev puas tsuaj rau lub qhov muag. Spectrally, lub teeb emissions los ntawm LED teeb yog txawv heev ntawm lub teeb emitted los ntawm tsoos incandescent thiab fluorescent teeb. Lub teeb emissions los ntawm incandescent teeb thiab fluorescent teeb muaj xya xim ntawm "liab, txiv kab ntxwv, daj, ntsuab, xiav, xiav thiab liab doog" zoo li lub hnub ci, tab sis lub teeb emission los ntawm zoo tib yam LED teeb muaj peb xim - liab, ntsuab, thiab xiav. . Blu-duab tshav" yog qhov yooj yim tshaj plaws thiab tseem ceeb tshaj plaws, txawm li cas los xij, tib neeg lub qhov muag tsis tuaj yeem raug lub teeb xiav ntev ntev, yog tias nws raug lub teeb xiav ntev dhau lawm, nws yuav ua rau cov tshuaj tiv thaiv photochemical puas rau lub retina, ua rau muaj kev cuam tshuam ntawm lub teeb xiav. Muaj ntau cov cytotoxic dawb radicals, yog li rhuav tshem cov kev loj hlob ib txwm thiab kev ua haujlwm ntawm cov hlwb retinal, thiab tseem ua rau cov retina puas.
