Ib, Txoj Cai Txheej Txheem: Qhov tseem ceeb sib txawv ntawm semiconductor luminescence thiab thermal poob tswj.
Txoj kev uas cov teeb pom kev zoo tso tawm lub teeb txwv lawv lub peev xwm los hloov lub zog kom zoo:
Fluorescent teeb: Cov hmoov fluorescent muab tawm lub teeb los ntawm ionizing mercury vapor. Nws tsuas muaj luminous efficiency ntawm 50-70 lumens / watt (lm / W) thiab xav tau ballast pib, uas siv zog ntau dua. Nws cov spectrum muaj ntau yam uas tsis yog-photosynthetically nquag hluav taws xob, xws li infrared, uas txhais tau hais tias kwv yees li 70% ntawm hluav taws xob hluav taws xob tau hloov mus ua thermal zog.
Lub teeb hlau halide siv lub siab -kub arc los ua kom cov hlau halides thiab ua rau lawv tawm lub teeb. Lub luminous efficiency tuaj yeem siab li 90-140 lm / W, tab sis qhov kub thiab txias ua haujlwm tuaj yeem dhau 1000 degree, thiab ntau dua 60% ntawm cov hluav taws xob thermal poob. Txhawm rau ua haujlwm, nws xav tau lub tshuab cua txias.
Aquarium Color-Hloov Waterproof Lightingemit lub teeb ncaj qha los ntawm electron qhov recombination nyob rau hauv semiconductor PN junctions, nrog lub teeb efficiency txog li 50-200 lm / W, thiab lub spectrum yuav raug kho kom raug mus rau ntau yam ntawm photosynthetically active hluav taws xob (PAR, 400-700nm). Piv txwv li, lub teeb xiav (450nm) thiab lub teeb liab (660nm) ntawm ib hom ntawm LED thoob dej yug ntses lub teeb muaj ntau dua 80% ntawm tag nrho cov teeb pom kev zoo, thiab lub zog siv ntau dua peb zaug siab dua li cov teeb pom kev zoo li niaj zaus. Tsis tas li ntawd, LED siv DC tsav, uas txhais tau hais tias tsis muaj ballast poob, thiab nws tsuas yog ua haujlwm ntawm qhov kub ntawm 40 thiab 60 degrees Celsius, uas txo cov nqi ntawm thermal tswj los ntawm ntau.
2, Kev sib piv ntawm kev siv hluav taws xob: kev soj ntsuam kom muaj nuj nqis ntawm cov ntaub ntawv (lab) thiab tiag tiag - cov xwm txheej hauv ntiaj teb
1. Qhov sib txawv ntawm qhov teeb pom kev ntau npaum li cas ib chav tso tawm thiab siv zog npaum li cas
Piv txwv li, yog tias koj xav tau PAR tus nqi ntawm 1000 μmol / m² / s:
Fluorescent teeb: xav tau txog 250W ntawm lub zog thiab siv 2190 kWh ntawm lub zog txhua xyoo (raws li 12 teev ntawm kev siv ib hnub).
Lub teeb hlau halide xav tau kwv yees li 150W ntawm lub zog, tab sis nws kuj xav tau lub kiv cua txias uas siv li 20W. Kev siv hluav taws xob tag nrho yog 1460 kWh / xyoo.
LED teeb tsuas yog siv 80W ntawm lub zog thiab siv 700 kWh ib xyoos twg. Lawv siv 68% tsawg zog dua lub teeb fluorescent thiab 52% tsawg zog dua hlau halide teeb.
2. Kev lees paub cov xwm txheej ntawm lub Hoobkas ua liaj ua teb
Kev koom tes ntawm Dalian Ocean University thiab cov tuam txhab ua liaj ua teb hauv Zhangzhou, Fujian Xeev qhia tau hais tias tom qab kev teeb tsa lub teeb pom kev zoo LED, kev siv lub zog ntawm ib chav tsev ntawm cov zis tau nqis los ntawm 0.8 kWh / kg mus rau 0.3 kWh / kg. Qhov no txuag ntau tshaj 120000 yuan ib xyoos ntawm cov nqi hluav taws xob. Lub kaw lus ua rau lub teeb pom kev zoo tshaj plaws los ntawm kev hloov cov spectrum dynamically (nrog lub teeb xiav ua lub hauv paus loj los txhawb kev noj zaub mov thaum nruab hnub thiab lub teeb liab yog qhov tseem ceeb kom txo qis kev ntxhov siab thaum hmo ntuj).
3. Tsev Neeg Aquarium Scene
Piv txwv li, 60cm × 30cm × 40cm thoob dej yug ntses:
Cov kev xaiv ib txwm muaj yog ob lub 40W fluorescent qhov muag teev uas siv 350 kWh ntawm hluav taws xob txhua xyoo.
LED kev daws teeb meem: Ib lub 24W puv -spectrum LED teeb uas siv 105 kWh ntawm lub zog ib xyoos twg thiab tsis tas yuav hloov ntau zaus (lub teeb fluorescent kav ntev li 8000 teev, thaum lub teeb LED kav ntev txog 50000 teev).
3, Lifecycle: Kev ua tiav tag nrho los ntawm cov ntaub ntawv tshiab rau kev tsim qauv
1. Qhov sib txawv ntawm cov ntaub ntawv tseem ceeb ntev npaum li cas
Lub teeb pom kev zoo nrog lub teeb fluorescent: Lub filament lub evaporation ua rau lub teeb ploj mus, thiab qhov chaw ntub dej nrawm nrawm rau oxidation ntawm cov electrodes, uas txhais tau hais tias qhov tseeb lifespan raug txiav ntau dua 30%.
Hlau halide teeb: Lub raj arc tig dub, uas ua rau lub teeb tsis zoo. Lub teeb kav ntev txog 12000 teev, tab sis hloov nws rau thiab tawm feem ntau tuaj yeem txiav nws lub neej nyob rau hauv ib nrab (qhov pib surge tam sim no yog peb npaug ntawm qhov ruaj khov- lub xeev tam sim no).
LED: Nws yog tsim los ntawm cov ntaub ntawv dav dav ntawm cov khoom siv semiconductor xws li gallium nitride (GaN) thiab yuav tsum kav ntev tshaj 100,000 teev. Cov khoom tiag tiag kav ntev dua vim yog cov qauv hauv qab no:
Epoxy resin encapsulation khaws noo noo thiab ntsev los ntawm corroding lub LED teeb. Hauv dej hiav txwv, IP67 waterproof LED teeb tuaj yeem kav ntev txog 50,000 teev.
Kev tsav tsheb tsis tu ncua tam sim no: Ib hom LED thoob dej yug ntses lub teeb khaws 90% ntawm nws qhov kev siv lub teeb qub tom qab 30000 teev kom tsis txhob poob lub teeb vim qhov hloov pauv tam sim no.
Optimizing tshav kub dissipation: Lub hlws ris kub yog khaws cia hauv qab 60℃nrog ib tug txhuas substrate thiab ib tug fin style kub dab dej. Qhov no yog 40℃qis dua nrog cov teeb pom kev zoo li niaj zaus.
2. Tag Nrho Cov Nqi Them Nqi Sib Piv Raws li 10-Xyoo Kev Siv Cycle:
Fluorescent teeb: Nws raug nqi 600 yuan los tswj lub teeb, uas txhais tau tias hloov lub raj 12 zaug (50 yuan txhua zaus). Tus nqi tag nrho yog 22500 yuan, uas suav nrog hluav taws xob.
LED teeb: Koj tsis tas yuav hloov lawv, thiab lawv tsuas yog raug nqi 7000 yuan hauv lub zog, uas tsuas yog 31% ntawm tus nqi ntawm qhov kev xaiv lub teeb fluorescent.
4, Cov txiaj ntsig zoo rau ib puag ncig: Tus nqi ntawm kev tswj cov pa phem hauv kev lag luam thiab kev tsim kho kom ruaj khov
1. Tshem tawm qhov kev pheej hmoo ntawm cov pa phem mercury
Txhua lub teeb fluorescent muaj kwv yees li 5 txog 10 milligrams mercury hauv nws. Thaum 1 billion lub teeb fluorescent raug pov tseg txhua xyoo, lawv tso 50 mus rau 100 tons ntawm mercury, uas ua rau dej paug thiab av rau lub sijhawm ntev. Mercury thiab txhuas tsis pom nyob rau hauv LEDs. Tom qab muab pov tseg, cov hlau muaj txiaj ntsig zoo li nyiaj thiab gallium tuaj yeem muab tau yooj yim sib cais thiab rov siv dua.
2. Pab nrog txiav cov pa roj carbon
Piv txwv li, nyob rau hauv Tuam Tshoj txoj kev lag luam aquaculture, hloov lub teeb fluorescent tam sim no nrog LEDs thiab suav cov hluav taws xob txhua xyoo ntawm 10 billion kWh yuav txiav carbon dioxide emissions los ntawm 8 lab tons (0.8 kg / kWh). Qhov no zoo ib yam li cog 440 lab tsob ntoo rau ib puag ncig.
3. Tsim kom zoo rau ib puag ncig
Qee lub teeb thoob dej yug ntses LED tuaj nrog cov duab biosensors uas tuaj yeem kuaj xyuas cov dej zoo hauv lub sijhawm tiag tiag thiab ua kom lub ecosystem sib npaug los ntawm kev hloov cov spectrum. Piv txwv li, thaum tus nqi ntawm algae ntau dua li qub, qhov tsis siv neeg nce ntawm lub teeb liab (660nm) nres algae los ntawm kev tsim tawm thiab txo qis qhov xav tau rau cov tshuaj algae tshem tawm.
