Niaj hnub no LED tau dhau los ua ib feem ntawm peb lub neej. Niaj hnub no, kuv yuav muab ib qho kev qhia luv luv rau koj txog lub tswvyim, yam ntxwv, thiab kev faib tawm.

Lub tswv yim ntawm LED

Ib qho LED (Lub Teeb Emitting Diode) yog ib qho khoom siv hluav taws xob semiconductor uas hloov hluav taws xob ncaj qha mus rau Lub Teeb. Lub plawv ntawm LED yog semiconductor nti, nrog ib kawg txuas mus rau ib tug scaffold, ib kawg ntawm uas yog ib tug tsis zoo electrode, thiab lwm yam kawg txuas mus rau qhov zoo kawg ntawm lub hwj chim mov, kom tag nrho cov nti yog nyob rau hauv ib tug epoxy cob.

Lub nti semiconductor yog tsim los ntawm ob qhov chaw, ib qho yog p-hom semiconductor, nyob rau hauv uas lub qhov dominate, thiab lwm yam ntawm uas yog ib tug n-hom semiconductor, uas electrons dominate. Tab sis thaum ob lub semiconductors txuas nrog, "pn junction" cov ntaub ntawv ntawm lawv. Thaum ib qho tam sim no siv rau lub nti los ntawm cov hlau, cov electrons raug thawb mus rau thaj tsam p, qhov chaw lawv rov sib sau ua ke nrog lub qhov thiab tawm lub zog hauv daim ntawv ntawm photons, uas yog li cas LEDs ci. Thiab lub wavelength ntawm lub teeb, xim ntawm lub teeb, yog txiav txim los ntawm cov khoom uas ua rau PN junction.

Cov yam ntxwv ntawm LED

Cov yam ntxwv tseem ceeb ntawm LED txiav txim siab tias nws yog lub teeb pom kev zoo tshaj plaws los hloov cov teeb pom kev ib txwm muaj, nws muaj ntau yam kev siv.

• Ntim me me

Ib qho LED yog ib qho me me nti ntim rau hauv epoxy resin, yog li nws yog qhov me me thiab lub teeb heev.

- Kev siv hluav taws xob tsawg

LED zog noj yog tsawg heev, feem ntau hais lus, LED khiav hauj lwm voltage yog 2-3.6V.
Kev ua haujlwm tam sim no yog 0.02-0.03A.
Hais tias yog, nws siv tsis ntau tshaj 0.1W ntawm hluav taws xob.

• Lub neej ua haujlwm ntev

Nrog rau txoj cai tam sim no thiab qhov hluav taws xob, LEDs tuaj yeem muaj lub neej ua haujlwm txog li 100,000 teev.

• High Brightness thiab Tsawg Thaum tshav kub kub

• Kev tiv thaiv ib puag ncig

LEDs yog tsim los ntawm cov khoom tsis muaj tshuaj lom, tsis zoo li cov teeb fluorescent, uas muaj mercury thiab ua rau muaj kuab paug. Lawv kuj tuaj yeem siv tau.

• Muaj zog thiab ruaj khov

LEDs yog tag nrho encapsulated nyob rau hauv epoxy resin, uas yog muaj zog tshaj ob lub teeb thiab fluorescent tubes.Nws kuj tsis muaj xoob qhov chaw nyob rau hauv lub teeb, uas ua rau cov LEDs indestructible.

Classification ntawm LED

1, Raws li lub teeb emitting rajximcov ntsiab lus

Raws li lub teeb emitting xim ntawm lub teeb emitting raj, nws muaj peev xwm muab faib ua liab, txiv kab ntxwv, ntsuab (thiab daj ntsuab, txheem ntsuab thiab ntshiab ntsuab), xiav thiab hais txog.
Tsis tas li ntawd, qee qhov LEDs muaj cov chips ntawm ob lossis peb xim.
Raws li lub teeb emitting diode tov los yog tsis tov nrog scatterers, xim los yog xim tsis muaj xim, cov saum toj no ntau yam xim ntawm LED kuj muab faib ua xim pob tshab, tsis muaj xim pob tshab, xim tawg thiab tsis muaj xim tawg ntawm plaub hom.
Scattering lub teeb-emitting diodes thiab lub teeb - emitting diodes yuav siv tau raws li qhov taw qhia teeb.

2.Raws li cov yam ntxwv ntawm luminousntontawm lub teeb emitting raj

Raws li cov yam ntxwv ntawm lub teeb emitting nto ntawm lub teeb emitting raj, nws muaj peev xwm muab faib ua round teeb, square teeb, rectangular teeb, lub ntsej muag lub teeb emitting raj, sab raj thiab micro raj rau nto installation, thiab lwm yam.
Lub teeb ci yog muab faib ua Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm thiab Φ20mm, thiab lwm yam.
Txawv teb chaws feem ntau sau cov Φ3mm lub teeb-emitting diode li T-1, φ5mm raws li T-1 (3/4), thiabφ4.4mm raws li T-1 (1/4).

3. Raws li covqauvntawm lub teeb-emitting diodes

Raws li cov qauv ntawm LED, muaj tag nrho cov epoxy encapsulation, hlau puag epoxy encapsulation, ceramic puag epoxy encapsulation thiab iav encapsulation.

4. Raws liluminous siv thiab ua haujlwm tam sim no

Raws li qhov luminous siv thiab ua hauj lwm tam sim no muab faib ua zoo tib yam brightness LED (luminous siv 100mCD);
Lub luminous siv nruab nrab ntawm 10 thiab 100mCD yog hu ua high brightness light-emitting diode.
Kev ua haujlwm tam sim no ntawm LED dav dav yog los ntawm kaum mA mus rau kaum tawm ntawm mA, thaum lub sijhawm ua haujlwm ntawm cov LED tam sim no qis dua 2mA (qhov ci ntsa iab yog tib yam li lub teeb pom kev zoo tib yam).
Ntxiv rau cov txheej txheem kev faib tawm saum toj no, kuj tseem muaj cov txheej txheem kev faib tawm los ntawm cov khoom siv chip thiab los ntawm kev ua haujlwm.

Ted: tsab xov xwm tom ntej no kuj yog hais txog LED. Nws yog dab tsi? Thov nyob twj ywm.
