LED (Lub Teeb Emitting Diode), lub teeb hloov hluav taws xob, yog qhov tseem ceeb muaj tsib cov khoom siv: nkhaus, nyiaj kua nplaum, nti, xaim kub, thiab epoxy cob.
LED (Lub Teeb-Kev-Diode) nyob rau hauv Suav txhais tau hais tias lub teeb hluav taws xob ua hluav taws xob) yog ib hom ntawm semiconductor uas tuaj yeem hloov kho hluav taws xob ua hluav taws xob. Nws hloov lub hauv paus ntsiab lus ntawm tungsten lub teeb tawm ntawm lub teeb roj incandescent thiab peb-thawj xim hmoov tso tawm ntawm lub zog-txuag teeb, thiab electroluminescence tau saws. Raws li kev txheeb xyuas, cov yam ntxwv ntawm LED yog pom tseeb heev, lub neej ntev, siab luminous efficiency, hluav taws xob tsawg thiab tsis tshua muaj zog noj. Yuav luag txhua qhov pom ntawm lub teeb ci dawb LED yog nyob rau hauv lub teeb pom lub teeb hloov kho, thiab nws txoj kev luminous efficiency tuaj yeem tshaj 150lm / W (2010). Sib piv LED nrog lub teeb pom kev zoo tib yam, cov kauv lub zog txuag teeb thiab T5 tri-xim fluorescent teeb, cov txiaj ntsig tau qhia tias: lub teeb pom kev zoo tib yam muaj lub teeb pom kev zoo ntawm 12lm / W thiab lub hnub nyoog tsawg dua 2000 teev, thiab lub zog kauv - txuag teeb muaj lub teeb pom kev zoo ntawm 60lm / W, uas yog tsawg dua Rau 8000 xuab moos, T5 fluorescent teeb yog 96lm / W thiab lub neej ntev li 10000 teev, thaum lub teeb dawb LED nrog lub taub 5 hli tuaj yeem thev dhau li ntawm 150lm / W, thiab lub sijhawm ua haujlwm ntev tshaj 100,000 teev. Qee tus neeg kuj kwv yees tias kev txwv qis ntawm LED lub neej yuav nyob mus ib txhis yav tom ntej. Nrog cov kev txhim kho tsis ntev los no hauv kev siv lub tshuab hluav taws xob tso cua sov, cov hluav taws xob loj ntawm txoj kev teeb pom kev zoo, cov dej nyab teeb thiab lwm cov hluav taws xob loj uas siv hluav taws xob rau cov teeb pom kev sab nraum zoov tau tiav kev lag luam thiab tau pib siv dav. Cov seev cev lub rooj teeb txawb thiab chav teeb ci rau sab hauv tsev teeb pom kev zoo uas yuav tsum muaj qhov kub xim thiab xim hloov xim kuj tau tsim ntau lawm thiab muab tso rau hauv kev siv. T8, T5, T4, cov teeb roj teeb thiab ntsia hlau teeb uas hloov cov roj incandescent thiab lub teeb txuag hluav taws xob nrog cov ntawv thov ntau tshaj plaws thiab kev siv ntau tshaj plaws tau serialized, nrog kev pab lub neej ntev txog 50,000 teev. LED teeb pom kev zoo tau nkag mus rau ib lub sijhawm ntawm kev txhim kho sai.
Lub ci ci ntawm LED yog qhov cuam tshuam nrog lub teeb taws lub kaum sab xis ntawm LED. Qhov me dua lub kaum sab xis ntawm LED, qhov siab dua qhov ci. Tsis muaj ib yam dab tsi super kaj thiab tsis yog super kaj. Nws yog lus dag rau cov menyuam yaus. Yog tias nws yog qhov zoo LED, tsis muaj qhov twg. Lub ci ci ntawm txhua tus neeg tsim los ntawm LED tuam ntxhab yog tib yam, tab sis cov txheej txheem ntau yam yog txawv, thiab kev pab cuam lub neej yog qhov txawv me ntsis, vim tias txhua tus siv cov LED chips txawv teb chaws. Yog tias nws yog 5MM LED, qhov kev siv luminous ntawm lub teeb dawb dawb ntawm 180 degree kaum sab xis tsuas yog Ob peb puas MCD, yog tias nws yog 15-degree kaum sab xis ntawm lub teeb siv, nws yuav mus rau ntau dua kaum txhiab thiab nees nkaum txhiab MCD Cov. Qhov sib txawv hauv lub teeb pom kev zoo yog kaum ob zaug. Yog tias nws siv rau kev siv teeb pom kev zoo, nws yog qhov zoo tshaj plaws los siv lub zog loj rau sab nraum zoov. Qhov ci ci ntawm cov LED tau siab dua, thiab lub zog ib leeg yog 1W, 3W, 5W, thiab qee qhov sib xyaw ua ke nrog ntau lub zog los ua lub siab ua haujlwm siab, thiab lub zog tuaj yeem ncav cuag ntau pua W.
