A teeb - emitting diode ( LED ) yog asemiconductor teeb qhov chaw uas tso tawm teeb thaum tam sim no ntws los ntawm nws. Electrons nyob rau hauv lub semiconductor recombinewith electron qhov, tso lub zog nyob rau hauv daim ntawv ntawm photons. Modern LEDs muaj nyob rau hauv lub pom, ultraviolet, thiab infrared wavelengths, nrog siab. teeb tso zis.
Ib yam li ntawd ib tug yuav nug, yuav ua li cas LED tsim teeb?
A teeb -emitting diode yog ob-leademiconductor teeb qhov chaw. Nws yog p -n kev sib tshuam diodethat tso tawm teeb thaum qhib Thaum ib qho hluav taws xob tsim nyog siv rau cov coj, cov khoom siv hluav taws xob tuaj yeem rov ua dua nrog electronholes hauv lub cuab yeej, tso tawm lub zog hauv daim ntawv ntawmphotons.
Ib tus kuj yuav nug, ua li cas cov dawb LEDs ua? LEDs tsis ncaj qha tsim dawb teeb. Siv lub xiav LED nrog phosphor txheej los hloov bluelight rau dawb Lub teeb los ntawm cov txheej txheem hu ua fluorescence. Combining liab, xiav thiab ntsuab LEDs los tsim dawb teeb. Dawb Lub teeb yog tsim los ntawm kev sib txawv ntawm qhov sib txawv ntawm tus neeg liab, xiav thiab ntsuab chips.
Ua raws li qhov xav tau, LED teeb lub teeb ua haujlwm li cas?
Teeb -tso tawm diodes ( LED ) yog cov khoom siv hluav taws xob. Raws li electrons dhau los ntawm hom semiconductor, nws hloov mus rau hauv teeb . Piv rau incandescentand CFL qhov muag teev , LED teeb muaj ntau npaum atturning zog rau hauv teeb . Yog li ntawd, tsawg zog ntawm lub zog noob li cua sov.
Lub ntsiab lus ntawm LED teeb yog dab tsi?
Sawv rau " Teeb -Emitting Diode. "Ib LED yog ib qho khoom siv hluav taws xob uas tso tawm teeb thaum hluav taws xob tam sim no dhau los ntawm nws. LEDs feem ntau yog siv rau qhov taw qhia teeb (xws li lub hwj chim qhib / tawm teeb ) ib qho khoom siv hluav taws xob.

Vim li cas kuv lub roj teeb teeb ci nrog lub roj teeb tshiab?
Ib qho yooj yim Circuit Court saib ntawm qhov hluav taws xob uas lub tshuab hluav taws xob tau tsim, thiab tig lub teeb roj teeb yog tias nws qis. Lub teeb roj teeb qhia txog teeb meem them roj teeb. Yog tias lub teeb roj teeb tuaj thiab nyob twj ywm thaum koj tab tom tsav tsheb, feem ntau ua rau yog siv lub tshuab hloov pauv tawg
Lub roj teeb LED Christmas teeb kav ntev npaum li cas?
Microdrop LED teeb tsim los ntawm cov xaim hluav taws xob tsis xeb yuav tsum nyob ntev tshaj 100 teev nrog cov txheej tshiab ntawm 3 AA roj teeb lossis 2 puag ncig C-style roj teeb thiab tus qauv LED roj teeb teeb teeb nrog cov rwb thaiv kom tuab thiab LED lo ntsiab muag yuav tsum nyob ntev li 18-24 teev ntawm ib txheej ntawm 3 AA roj teeb
Kev sib xyaw ua ke LED teeb lub teeb txhais li cas?
Integrated LED teeb muaj cov LEDs ua tau rau hauv lub fixture nws tus kheej. Ib qho kev siv rau cov kev xaiv retrofit tseem ceeb txhais tau hais tias siv lub teeb LED hauv lub teeb pom kev zoo (nrog rau E26 / nruab nrab puag lossis E12 / candelabra lub qhov (socket), uas yog qhov feem ntau)
Lub teeb LED tuaj yeem khiav ntawm lub roj teeb ntev npaum li cas?
Khawm hlwb tuaj yeem muaj peev xwm los ntawm kwv yees li 45 txog 100 mAh. Yog li ntawd, LED teeb duab 1mA yuav kav ntev li ntawm 45 mus rau 100 teev. Muaj ntau lub LEDs dim heev ntawm 1 mA. Raws li Duracell, tus qauv CopperTop AA cell muaj peev xwm ntawm 2000 thiab 3000 mAH nyob ntawm seb nws siv li cas thiab qhov kawg ntawm lub neej yog txiav txim siab
