Tam sim no LED tau dhau los ua ib feem uas tsis tau txais ntawm peb lub neej. Niaj hnub no, Kuv yuav muab cov lus qhia luv luv rau cov tswvyim, cov yam ntxwv, thiab kev faib tawm.
Lub tswvyim ntawm LED
Ib LED (Teeb qhib Diode) yog lub zog-lub xeev semiconductor ntaus ntawv uas hloov hluav taws xob ncaj qha rau lub teeb. Lub plawv ntawm LED yog ib kawg txuas nrog ib qho kawg ntawm lub zog hluav taws xob, yog li cov nti tag nrho tau muab ntim rau hauv ib qho epoxy cob.
Lub nti nti semiconductor yog tsim los ntawm ob ntu, ib qho yog ib qho yog p-hom semiconductor, thiab lwm qhov yog n-li hluav taws xob soob, nyob rau ntawm lub tshuab hluav taws xob nyob. Tab sis thaum ob tus semiconductors txuas nrog, "PN hlws rau" ntawm lawv. Thaum cov khoom siv tam sim no tau thov rau lub nti los ntawm cov hlau, cov hluav taws xob tau thawb mus rau lub qhov thiab emit nyob rau hauv daim ntawv ntawm photons, uas yog li cas leds. Thiab nthwv dej ntawm lub teeb, xim ntawm lub teeb, yog txiav txim siab los ntawm cov khoom siv pn hlws ris.
Cov yam ntxwv ntawm LED
Cov yam ntxwv ntawm Intrinsic ntawm Led txiav txim siab tias nws yog qhov teeb pom kev zoo tshaj plaws los hloov cov teeb tsa keeb kwm, nws muaj ntau cov ntawv thov.
- Cov ntim me me
Ib qho LED yog qhov tseem ceeb heev nti encapsulated nyob rau hauv epoxy cob, yog li nws yog qhov me me thiab lub teeb heev.
-Low Hwj chim noj
LED Fais zib tau noj yog tsawg heev, feem ntau hais lus, LED Kev Ua Haujlwm Hluav Taws Xob yog 2-3.6V.
Cov hauj lwm tam sim no yog 0.02-0.03a.
Uas yog hais, nws noj tsis ntau tshaj 0.1w ntawm hluav taws xob.
- Lub Neej Muaj Kev Pab Ntev
Nrog txoj cai tam sim no thiab voltage, leds tuaj yeem muaj kev pabcuam lub neej txog li 100,000 teev.
- Lub teeb ci siab thiab tsawg cua sov
- Kev tiv thaiv ib puag ncig
LEDs yog ua los ntawm cov ntaub ntawv uas tsis muaj tshuaj lom, tsis zoo li cov roj ntsha fluorescent, uas muaj mercury thiab ua kom muaj kuab paug. Lawv kuj tseem tuaj yeem rov ua dua tshiab.
- Muaj zog thiab ruaj khov
LEDs yog tag nrho cov khoom nyob hauv epoxy cob, uas muaj zog tshaj ob lub teeb thiab fluorescent leeg.Yog tsis muaj xoob ntawm lub teeb, uas ua rau cov ledestructible.
Kev faib tawm ntawm LED
1, raws li lub teeb pom kevximCov ntsiab lus
Raws li lub teeb emitting ntawm lub teeb emitting, nws tuaj yeem faib ua liab, ntsuab (thiab ntsuab ntsuab), xiav thiab.
Tsis tas li ntawd, qee cov coj muaj cov chips ntawm ob lossis peb xim.
Raws li lub teeb emitting los yog tsis sib xyaw nrog cov npaws, xim lossis xim ntau sab xim av, xim ua kom tawg thiab tsis muaj xim plaub hom.
Scattering lub teeb-emitting Diodes thiab lub teeb - Emitting Diodes tuaj yeem siv raws li qhov taw qhia teeb.
2.according rau cov yam ntxwv ntawm luminousnplaimntawm lub teeb emitting raj
Raws li cov yam ntxwv ntawm lub teeb emitting ntawm lub teeb emitting, nws tuaj yeem faib ua lub teeb puag ncig, lub raj raj maub rau saum npoo av, thiab lwm yam.
Lub teeb ci ntsa iab tau muab faib ua φ2mm, φ4.4mm, φ5mm, φ5mm, φ5mm, φ10mm, thiab lwm yam.
Txawv teb chaws feem ntau sau cov teeb ci φ3mm lub teeb-emitting Diode li T-1, φ5 hli li T-1 (3/4), thiabφ4.4mm li T-1 (1/4).
3.Ccording rau lublub tsevntawm lub teeb-emitting diodes
According to the structure of LED, there are all epoxy encapsulation, metal base epoxy encapsulation, ceramic base epoxy encapsulation and glass encapsulation.
4.According rauluminous siv thiab ua haujlwm tam sim no
Raws li cov luminous siv thiab ua haujlwm tam sim no tau muab faib ua ke rau hauv qhov ci ci zoo li coj (luminous siv 100MD);
Kev siv luminous ntawm 10 thiab 100mcd yog hu ua siab lub teeb ci ntsa iab-emitting diode.
Cov hauj lwm tam sim no LED yog los ntawm kaum ma mus rau kaum ob, thaum ua haujlwm tam sim no LED Tam Sim No yog tib yam li lub teeb pom kev zoo ib yam).
Ntxiv rau cov txheej txheem sib kawm saum toj no, tseem muaj cov txheej txheem ntawm kev faib tawm los ntawm cov khoom nti thiab los ntawm kev ua haujlwm.
TED: Tshooj lus tom ntej yog kuj yog hais txog LED. Nws yog dab tsi? Thov nyob tuned.
