LED txoj kev teeb pom kev zoo tsis yog lub zog txuag ntawm theem no?
Nws yog ib qho kev nkag siab zoo uas thaum sib tham txog qhov teeb meem, koj yuav sawv ntawm koj tus kheej. Debating koj tus kheej cov kev xav yuav yeej ib txwm yeej lub sab tes. Qhov no yog qhov kev nkag siab zoo. Muaj ntau qhov kev sib cav txog LED teeb pom kev zoo, uas tuaj yeem piav qhia tias yog" kub" los ntawm cov neeg koom. Ua ntej kev sib cav, kuv xav tias txhua tus yuav paub tias leej twg tuaj yeem yeej! Qhov laj thawj yog yooj yim. Lub neej yav tom ntej yog tias LEDs tsis xav tsis thoob, nws tsuas yog lub sijhawm xwb. Obstacles rau lub sij hawm kev vam meej yog tsis muaj dab tsi ntau tshaj li ob yam, ib tug yog lub teeb efficiency; lwm qhov yog cov nqi ua haujlwm.
Thaum peb saib yeeb yaj kiab, peb ntsib kev ncaj ncees thiab kev tawm tsam phem. Peb txhua tus yuav nkag siab txog qhov kawg. Tam sim no koj tsuas yog saib cov txheej txheem. Nws' tsuas yog qhov piv txwv zoo tshaj plaws rau" LED Teeb Pom Kev Sib Tham." Kuv xav tias nws yog qhov zoo dua los ua cov tswv yim, es tsis txhob them se rau cov neeg them se rau qhov project teeb pom kev zoo LED. Lub xeev' kev nqis peev yuav tsum feem ntau yog LED cov kev tshawb fawb hauv daim ntawv thov, uas muaj txiaj ntsig zoo rau kev txhim kho tag nrho LED kev lag luam.
Feem ntau, LED teeb pom kev tsim teeb pom kev zoo yog halved piv rau cov khoom siv hluav taws xob txuag hluav taws xob. Piv txwv li: LED tsim rau 40W fluorescent raj feem ntau siv tsawg dua 20W zog; 250W txoj kev teeb siv LED txoj kev teeb feem ntau tsim los txog li 100W lub zog. Qhov no yog vim li cas LED teeb pom kev zoo txuag hluav taws xob. Yog hais tias peb ncaj qha mus rau ib nrab ntawm lub hwj chim ntawm cov tsoos teeb, kev txuag hluav taws xob yuav muaj qhov zoo tib yam.
Vim li cas lub hwj chim halved tsim yuav tsum tau? Qhov laj thawj tseem ceeb yog tus nqi. Tus nqi tuaj yeem muab faib ua tus nqi ncaj qha thiab cov khoom siv hluav taws xob kub dissipation. Nyob rau theem no, tus nqi tsim ntawm LED teeb pom kev zoo yog 10 npaug ntawm cov khoom siv hluav taws xob txuag hluav taws xob, thiab kev tsim hluav taws xob ib nrab yog qhov zoo tshaj plaws los txo cov nqi. Nrog rau qhov nce ntawm lub zog tseem ceeb ntawm LED teeb tsim, tus nqi yuav nce exponentially, thiab tus qauv tsim txawm tias tsis tuaj yeem ua tiav. Xav txog cov nqi thiab cua kub dissipation tej yam kev mob ntawm ib txoj kev teeb centralized tsim ntawm 250W?
LED teeb pom kev zoo muaj" coj txoj kev xav". Qhov laj thawj yog vim li cas LED muaj qib siab ntawm kev coj ncaj ncees ntawm lub teeb, thiab lub teeb tawm tau siv tag nrho mus rau pem hauv ntej. Rau kuv tus kheej, kuv tsis tawm tsam cov lus qhuab qhia no, thiab kuv tsis pom zoo rau qhov kev xav no. Kuv vam tias peb txhua tus yuav saib qhov teeb meem no raws li kev xav. Thaum tsim cov khoom, nws yog ib qho tsim nyog yuav tsum muaj kev cuam tshuam lub teeb los ntawm lub periphery thiab sab nraum qab mus rau pem hauv ntej rau kev siv tsim nyog kom ua tiav qhov zoo tagnrho condensing nyhuv. Cov teeb pom kev zoo ib txwm siv los ua qhov no. LEDs tsis tuaj yeem tiv taus qhov kub thiab txias dua thiab xav tau qhov chaw hla ntu txaus los ua kom sov, txwv tsis pub nws tuaj yeem txuas rau pob 360-degree teeb-emitting LEDs.
LED directivity yog qhov tshwm sim ntawm cov qauv kho qhov muag ntawm lub pob bracket. Lub"directivity theory" yog" cawm txoj sia straw" piav qhia txog LED kev txuag hluav taws xob nyob rau theem no. Los ntawm keeb kwm kev loj hlob taw tes ntawm view, muaj ib tug precedent nyob rau hauv no hais txog.
Ob peb xyoos dhau los, domestic LED miner lub teeb tsim manufacturers siv 8 hli me me-lub kaum sab xis LED tsim miner lub teeb. Qhov kev coj ncaj ncees ua tau raws li cov qauv kev nyab xeeb ntawm lub teb chaws thee mine. Qhov ci tuaj yeem pom ntawm ib nrais muag. Nws yog qis dua li cov teeb pom kev zoo. Rau peb cov miners, peb tsuas muaj txoj cai tsis mus rau kuv, tsis muaj txoj cai xaiv lub teeb yuav siv li cas, tab sis kuv kuj txais lub teeb no nyob rau hauv cov xwm txheej ntawm kev soj ntsuam xwb.
Tib yam muaj tseeb rau qhov teeb meem ntawm txoj kev teeb pom kev zoo. Qee yam tsis tuaj yeem tswj hwm los ntawm pawg neeg dav dav. Txhawm rau kom zoo nkauj, cov teeb pom kev zoo yuav raug teeb tsa nrog symmetrical 4-10 kab ntawm txoj kev teeb pom kev zoo. Nco ntsoov hais tias nyob rau hauv lub hometown, tsuas yog 1-2 kab teeb yuav qhib thaum hmo ntuj kom txuag tau hluav taws xob, tab sis nyob rau hauv Shenzhen, tag nrho cov teeb txoj kev yuav taws txawm ntau npaum li cas. Yog li peb puas thuam qhov tsis muaj teeb pom kev hauv peb lub nroog lossis qhuas tsoomfwv' kev lag luam pragmatic? Los yog nws puas txhais tau tias Shenzhen' lub zog nyiaj txiag tsis saib xyuas, lossis thuam Shenzhen rau kev khib nyiab dhau lawm? Ib zaug ntawm 3 o' teev sawv ntxov, los ntawm Shenzhen Luohu mus rau Shekou, Kuv tsis tau' tsis pom txoj kev teeb pom kev ci ntsa iab ib nrab ntawm lub sijhawm, thiab kuv tsis tau' tsis pom txoj kev teeb pom kev raug muab tua ib nrab.
Nws yog" nyuaj" txaus siab rau lub hli ntawm txoj kev ntawm Shenzhen thaum hmo ntuj. Thaum peb tseem hluas, peb siv cov roj roj teeb los kawm, thiab peb tsis xav pom. Kuv tsis paub tias nws yuav zoo li cas thaum rov qab mus rau yav dhau los. Nws tau hais tias thaum Shuji Nakamura, leej txiv ntawm Blu-duab tshav, tau hais lus hauv Sichuan University, nws tsuas tuaj yeem pom qhov pom ntawm Blu-duab tshav. Lub sijhawm ntawd, cov menyuam kawm ntawv zoo siab heev. Tam sim no koj xav pom dab tsi yog tias koj ntsib nws?
Nws yog qhov yooj yim tshaj plaws rau kev tsim cov khoom kom ua raws li cov qauv hauv lub tebchaws, tab sis nws yuav tsum tau lees paub los ntawm cov pej xeem, thiab nws yuav siv sij hawm los xyuas. Cov kev xav ntawm ob peb tus neeg yog rau kev siv nkaus xwb, thiab tsis muaj qhov xaus yooj yim tuaj yeem kos. Kuv tseem hais tias" lub zog-txuag kev taw qhia txoj kev xav, Kuv tsis pom zoo nrog nws, thiab kuv tsis tawm tsam nws."
