Qhov kev paub tshaj plaws ntawm LED teeb hlaws, yam ntxwv thiab tsis
Teeb pom kev zoo 2013-08-22 LED Cov Lus Qhia Txuj Ci LED cov hlaws dai tau tsim los ntawm cov nplais, kua nplaum, phosphor, xaim kub, thiab cov khoom sib dhos.
Hais txog LED teeb hlaws, muaj ntau thiab zoo tshaj qhia hauv Internet. Piv txwv li, kev qhia txog LED teeb hlaws dai ntawm Baidu Encyclopedia yog tus kws tshaj lij thiab ntxaws ntxaws. Kuv yuav tsis rov hais dua kev tshaj lij ntawm no, tab sis kuv yuav muab cov lus qhia nrov rau koj kom cov neeg tsis muaj kev paub yooj yim tuaj yeem nkag siab thiab nkag siab LED teeb hlaws dai.
Txhawm rau muab nws bluntly, LED teeb hlaws yog qhov tseeb ntawm lub teeb me me. Lub teeb kawg yog lub nti ntim rau hauv lub teeb LED hlaws, thiab qhov yuav tsum tau ua ntej rau lub teeb kom pom kev yog kev coj ua, thiab kev ua tiav yog ua tiav los ntawm cov xov tooj kub thiab cov khoom sib dhos. Yog li dab tsi yog lub luag haujlwm ntawm kua nplaum thiab phosphor? Feem ntau los tiv thaiv cov nti thiab sib txuam xim. Peb tau pom tias LED teeb uas tso xim sib txawv feem ntau pom los ntawm kua nplaum thiab phosphor.
Kev faib tawm ntawm LED teeb hlaws
Raws li lub zog: nws tuaj yeem faib ua cov hlaws hluav taws xob qis (qis dua 0.5W), nruab nrab lub zog teeb hlaws (0.5W), thiab lub teeb lub zog loj hlaws (siab dua 0.5W).
Raws li txoj hauv kev ntim khoom: tuaj yeem faib ua cov kaus mom lub teeb lub teeb hlaws, thaj teeb hlaws, COB teeb hlaws
Raws li cov xim ci: nws tuaj yeem faib ua lub teeb dawb, lub teeb liab, lub teeb xiav, lub teeb ntsuab thiab lwm yam.
Nta
1. Kev nyab xeeb siab: Qhov ua haujlwm ntawm LED teeb hlaws yog feem ntau ntawm 3.0-3.5V, yog li kev nyab xeeb siab, txawm tias hluav taws xob poob, tsis muaj kev phom sij.
2. Daim ntawv thov hloov pauv: Vim nws qhov loj me, nws tuaj yeem siv tau yooj yim los ua teeb ntawm ntau qhov ntau thiab tsawg thiab hom.
3. Lub neej ntev: Hauv kev xav, lub neej ntawm LEDs yog 100,000 teev, thaum lub teeb roj teeb tsuas yog 1,000 teev, thiab lub zog txuag hluav taws xob teeb yog 8,000 teev.
4. Cov pa roj carbon tsawg thiab kev tiv thaiv ib puag ncig: Nws tsis muaj cov tshuaj phem, xws li mercury thiab lwm yam hlau hnyav, yog li nws yog ib puag ncig zoo heev, thiab nws lub teeb pom kev zoo txiav txim siab nws cov pa roj carbon tsawg thiab txuag lub zog.
5. Kev ua haujlwm siab luminous: kev ua kom pom kev zoo ntawm cov roj teeb yog li 15 lm/W, lub zog txuag hluav taws xob fluorescent yog 50-60 lm/W, thiab LEDs yog 100-120 lm/W (Cree Labs yog 276 lm/W, Lub Ob Hlis 2013 cov ntaub ntawv).
6. Lub teeb pom kev zoo: Tsis muaj lub teeb ci ultraviolet nyob rau hauv lub teeb, uas tsis muaj kev phom sij rau tib neeg kev noj qab haus huv.
Parameter
1. Brightness: chav lm (lumens), siab dua lumens, ci dua.
2. Wavelength:
Lub teeb dawb: xim sov (xim kub 2700-4000K), dawb huv (xim kub 5500-6000K), txias dawb (xim kub siab tshaj 7000K)
Lub teeb liab: nthwv dej 600-680, ntawm uas 620 thiab 630 feem ntau yog siv rau teeb theem, thiab 690 nyob ze rau infrared
Lub teeb xiav: Band 430-480, ntawm qhov 460 thiab 465 theem teeb tau siv ntau dua
Lub teeb ntsuab: qhab 500-580, ntawm qhov 525,530 theem teeb tau siv ntau dua
3. Lub teeb ci ntsa iab: LEDs nrog lub hom phiaj sib txawv muaj lub kaum sib txawv ntawm lub teeb ci.
4. Antistatic muaj peev xwm: LED teeb hlaws nrog muaj zog tiv thaiv muaj peev xwm muaj lub neej ntev thiab tus nqi siab. Feem ntau, tsuas yog LED teeb hlaws dai nrog tus nqi tiv thaiv zoo dua 700V tuaj yeem siv rau teeb pom kev zoo LED.
5. Kev xau tam sim no: LED teeb hlaws dai yog lub cev tsis muaj kev coj ua zoo. Yog tias muaj qhov hloov pauv tam sim no, nws hu ua to. LED teeb hlaws dai nrog cov xau loj tam sim no muaj lub neej luv thiab tus nqi qis.
