1. High luminous efficiency ntawm LED teeb qhov chaw
Kev sib piv luminous efficiency: incandescent teeb nyhuv yog 10-15lm, halogen tungsten lub teeb nyhuv yog 12-24 lumens/watt, fluorescent teeb yog 50-90 lumens / watt, sodium teeb yog 90-140 lumens / watt, thiab feem ntau ntawm kev siv hluav taws xob ua cua sov poob.
LED teeb pom kev zoo: nws tuaj yeem tso tawm 50-200 lumens / watt, thiab muaj monochromaticity zoo thiab nqaim spectrum. Nws tuaj yeem ncaj qha emit xim pom lub teeb yam tsis tau lim.
2. Tsawg zog noj ntawm LED teeb qhov chaw
LED ib lub raj fais fab yog 0.03-0.06W, DC tsav tau txais, thiab ib lub raj tsav hluav taws xob yog 1.5-3.5V. Qhov tam sim no ntawm 15-18 mA yog ceev thiab tuaj yeem ua haujlwm ntawm qhov zaus. Thaum siv nrog tib lub teeb pom kev zoo, kev siv hluav taws xob yog ib kaum txhiab ntawm cov teeb pom kev zoo thiab ib nrab ntawm cov raj fluorescent. Nyiv kwv yees hais tias yog ib nrab ntawm Nyiv lub teeb incandescent thiab cov teeb fluorescent hloov los ntawm LEDs nrog lub teeb pom kev zoo ob zaug siab dua li cov teeb fluorescent, qhov kev txuag roj txhua xyoo yog sib npaug li 6 billion litres. Lub teeb fluorescent nrog cov nyhuv tib yam siv ntau dua 40 watts, thaum lub zog ntawm txhua LED tsuas yog 18 watts.
3. Lub neej ua haujlwm ntev ntawm LED teeb qhov chaw
Incandescent teeb, fluorescent teeb thiab tungsten halogen teeb yog cov yam ntxwv ntawm hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob, hluav taws xob yooj yim, thermal deposition, lub teeb attenuation, thiab lwm yam, thaum LED teeb yog me me, lub teeb nyob rau hauv qhov hnyav, thiab encapsulated nrog epoxy resin, uas tuaj yeem tiv taus. Lub zog muaj zog txhua yam kev poob siab thiab kev co, thiab tsis yooj yim rau kev tawg, nrog lub neej nruab nrab ntawm 30000 txog 50000 teev. Lub neej kev pab cuam ntawm LED teeb tuaj yeem ncav cuag 3-5 xyoo, uas tuaj yeem txo cov nqi kho cov teeb pom kev zoo thiab zam qhov mob ntawm kev hloov lub teeb ntau zaus.
4. Muaj kev nyab xeeb thiab kev ntseeg siab
Tsawg tus nqi calorific, tsis muaj hluav taws xob thermal, lub teeb txias txias, kov kev nyab xeeb, tswj kom raug ntawm lub teeb hom thiab luminous lub kaum ntse ntse, lub teeb xim, tsis muaj glare, tsis muaj mercury, sodium thiab lwm yam khoom uas yuav ua rau muaj kev phom sij rau kev noj qab haus huv.
5. LED teeb qhov chaw muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig
LED yog tag nrho cov khoom luminous lub cev, uas yog cuam tshuam resistant thiab tsis yooj yim rau tawg, recyclable pov tseg, tsis muaj kuab paug, thiab yuav txo tau cov tiam ntawm ib tug loj tus naj npawb ntawm cov teeb meem gases xws li sulfur dioxide thiab nitrogen, raws li zoo raws li lub tsev cog khoom gases xws li. raws li carbon dioxide los txhim kho tib neeg lub neej nyob ib puag ncig. Nws tuaj yeem hu ua "lub teeb ntsuab"
Tam sim no, muaj peb lub thev naus laus zis los tsim cov LED dawb: ib qho yog sib xyaw xim liab, ntsuab thiab xiav ultrahigh brightness LEDs uas tuaj yeem tsim los ntawm kev siv peb lub ntsiab xim xim thiab qhov sib piv ntawm lub teeb siv 3: 1: 6 los ua xim dawb. ; lwm qhov yog siv lub ultrahigh InGan xiav LED, nrog ib qho me me ntawm phosphor raws li yttrium pob zeb diamond garnet ntawm lub raj sib dhos, uas tuaj yeem tsim lub teeb daj ntsuab nyob rau hauv lub excitation ntawm lub teeb xiav, thiab lub teeb daj ntsuab no tuaj yeem tsim lub teeb dawb nrog lub teeb xiav pob tshab; Qhov thib peb yog tsis yog ultraviolet LED, Ultraviolet lub teeb yog siv los ua kom peb lub ntsiab phosphors los yog lwm yam phosphors los tsim lub teeb dawb sib xyaw los ntawm ntau xim.
6. LED teeb qhov chaw yog ntau zog-txuag
Tau kawg, kev txuag hluav taws xob yog qhov laj thawj tseem ceeb vim li cas peb xav txog kev siv LED. Tej zaum LED yog kim dua li cov teeb pom kev zoo ib txwm muaj, tab sis nws yuav siv sij hawm ib xyoos ntawm kev txuag hluav taws xob kom rov qab tau cov peev txheej hauv cov teeb pom kev zoo, yog li peb tuaj yeem tau txais ob peb zaug ntawm kev txuag hluav taws xob txhua xyoo hauv 4-9 xyoo.
