LED hlaws sawv ntsug rau lub teeb-emitting diodes.
Nws lub ntsiab lus luminous yog tias PN junction davhlau ya nyob twg voltage tsim ib qho kev cuam tshuam muaj peev xwm, thaum ntxiv rau pem hauv ntej bias voltage ntxiv, qhov muaj peev xwm cuam tshuam poob, thiab feem ntau cov neeg nqa khoom hauv P thiab N aav diffuse rau ib leeg. Txij li thaum lub tshuab hluav taws xob muaj ntau dua qhov kev txav mus los ntawm lub qhov, ntau tus electrons yuav diffuse mus rau P-region, uas yog qhov kev txhaj tshuaj ntawm cov neeg nqa khoom tsawg hauv P-region. Cov electrons no ua ke nrog cov qhov nyob rau hauv lub valence band, thiab lub zog tshwm sim yog tso tawm raws li lub teeb lub zog.
Nws cov yam ntxwv yog raws li nram no:
1. Voltage: LED teeb hlaws siv hluav taws xob tsis tshua muaj hluav taws xob, lub zog hluav taws xob ntawm 2-4V.Raws li cov khoom sib txawv, nws tau tsav los ntawm lub zog hluav taws xob muaj kev nyab xeeb dua li cov khoom siv hluav taws xob siab, tshwj xeeb tshaj yog tsim rau cov pej xeem.
2. Tam sim no: kev khiav hauj lwm tam sim no yog 0-15mA, thiab qhov ci ci yuav ci dua nrog qhov nce ntawm tam sim no.
3. Kev ua tau zoo: 80% tsawg zog siv dua li cov teeb pom kev zoo nrog tib lub teeb pom kev zoo.
4. Kev siv tau: Txhua chav LED nti yog 3-5mm square, yog li nws tuaj yeem npaj rau hauv ntau yam duab ntawm cov khoom siv, thiab haum rau qhov chaw hloov pauv.
5. Lub sij hawm teb: Lub sij hawm teb ntawm nws lub teeb incandescent yog qib millisecond, thiab cov teeb ntawm LED yog qib nanosecond.
6. Ib puag ncig muaj kuab paug: Tsis muaj teeb meem hlau mercury.
7. Xim: Xim tuaj yeem hloov tau los ntawm qhov tam sim no, coj los ntawm kev hloov kho tshuaj, kho cov qauv band thiab band sib txawv ntawm cov khoom, kom ua tiav xim liab, daj, ntsuab, xiav, txiv kab ntxwv ntau xim lub teeb. Piv txwv li, thaum qhov qis tam sim no yog liab LED, nrog rau qhov nce ntawm tam sim no, tuaj yeem tig txiv kab ntxwv, daj, thiab thaum kawg ntsuab.
Nws parameters tau piav raws li hauv qab no:
1. Kev ci ntsa iab
Tus nqi ntawm cov hlaws LED muaj feem xyuam rau qhov ci.
Lub ci ci ntawm cov hlaws dai yog 60-70lm. Qhov dav dav ntawm lub teeb lub teeb yog 80-90lm.
Lub ci ci ntawm 1W lub teeb liab feem ntau yog 30-40 lm. Lub ci ci ntawm 1W ntsuab lub teeb feem ntau yog 60-80 lm. Lub ci ci ntawm 1W daj lub teeb yog feem ntau 30-50 lm. Lub ci ci ntawm 1W xiav lub teeb feem ntau yog 20-30 lm.
Lus Cim: 1W brightness yog 60-110LM. 3W brightness mus txog 240LM. 5W-300W yog integrated nti, nrog series / parallel pob, feem ntau nyob ntawm seb muaj pes tsawg tus tam sim no, voltage.
LED lens: PMMA, PC, kho qhov muag iav, silica gel (mos silica gel, nyuaj silica gel) thiab lwm yam ntaub ntawv feem ntau yog siv rau thawj lub lens. Qhov loj ntawm lub kaum sab xis, lub teeb efficiency ntau dua. Nrog lub kaum sab xis LED me me, lub teeb yuav tsum nyob deb.
2. wavelength
Tib wavelength thiab xim ua rau tus nqi siab.
Lub teeb dawb muab faib ua xim sov (xim kub 2700-4000K), zoo dawb (xim kub 5500-6000K) thiab txias dawb (xim kub siab tshaj 7000K).
Lub teeb liab: band 600-680, ntawm 620,630 feem ntau yog siv rau theem teeb thiab 690 yog ze rau infrared.
Blu-duab tshav: Band 430-480, ntawm 460,465 feem ntau yog siv rau theem teeb.
Lub teeb ntsuab: Band 500-580, ntawm 525,530 feem ntau yog siv rau theem teeb.
3. Lub kaum ntse ntse
LEDs rau lub hom phiaj sib txawv emit lub teeb ntawm ntau lub ces kaum. Tshwj xeeb luminous Angle yog kim dua.
4. Antistatic muaj peev xwm
Antistatic muaj peev xwm ntawm LED teeb hlaws muaj lub neej ntev, yog li tus nqi siab. Feem ntau ntau tshaj 700V antistatic LED teeb hlaws tuaj yeem siv rau LED teeb pom kev zoo.
5. Cov dej ntws tam sim no
LED teeb hlaws yog ib-txoj kev conductive luminous lub cev. Yog tias muaj qhov rov qab tam sim no, nws yog hu ua to, leakage tam sim no LED teeb hlaws muaj lub neej luv luv thiab tus nqi qis.
Eurborntsim cov teeb sab nraum zoov hauv Suav teb. Peb ib txwm xaiv cov khoom lag luam raws li lub teeb thiab sim peb qhov zoo tshaj plaws los ua kom cov khoom zoo meej.
