Kev siv LED teeb pom kev zoo hauv kev tsim khoom yug me nyuam
Lub teeb tuaj yeem nkag mus rau tus qaib lub qhov muag thiab taug kev los ntawm pob txha taub hau mus rau hypothalamus thiab pineal qog, txhawb lawv.
nqi teeb pom kev zoo
Nrog rau qhov txiaj ntsig ntawm tus nqi qis qis zog, LED lub teeb tau pom nyob rau ob peb xyoos dhau los uas nws tuaj yeem siv los tsim cov khoom lag luam niam txiv ib yam li cov teeb pom kev zoo. High-pressure sodium teeb yuav txuag tau cov nqi hluav taws xob los ntawm 40 feem pua ntawm ib lub sijhawm 5-xyoo thaum piv rau cov teeb ci. Txawm li cas los xij, dhau ib lub sijhawm 5-xyoo, compact fluorescent thiab LED teeb yuav txo qis kev siv nyiaj los ntawm 63 feem pua thiab 73 feem pua.
Cov txiaj ntsig ntawm LED teeb thiab cov raj
Currently, LED lights/tubes or strings make up the majority of new lighting installations because of their low energy consumption when compared to conventional lamps, extended lifespan (>50,000 teev), dimming peev xwm, thiab customizable xim tso zis. Lawv kuj muab tus nqi siab Ingress Protection, yooj yim rau ntxuav, ntxuav, thiab tshuaj tua kab mob, thiab (IP; cuam tshuam rau qib ntawm plua plav thiab av noo nkag mus). Feem ntau, 2,700K (lub teeb sov) nrog lub dimmer system yog qhia rau kev loj hlob thiab ntau lawm. Piv rau lub teeb txias, lub teeb sov nyiam tiv thaiv cov qe hauv pem teb (6,000K).
influences kev tswj yug me nyuam
Kev tswj cov neeg yug tsiaj tau cuam tshuam los ntawm LED teeb pom kev zoo. Tam sim no nws muaj peev xwm ua haujlwm nrog cov teeb pom kev tsawg tsawg ntawm 1.5 mus rau 2 Lux thiab tseem pom zoo txaus los tswj cov noog ua tsaug rau kev tsim khoom ntawm dimmer units (dub mus rau kaj ntug). Tsis-dimmable LED teeb yog nyiam los ntawm qee tus thawj coj ua liaj ua teb. Kev tswj hwm tau txhawj xeeb tias qee qhov xwm txheej, qee tus neeg ua haujlwm tuaj yeem hloov kho qhov chaw, uas yuav muaj kev cuam tshuam loj rau cov noog lub teeb rhiab heev (refractory) thaum kawg ntawm lub sijhawm tu. Yog li ntawd, nws yog ib qho tseem ceeb uas cov dimmers ntawm cov liaj teb uas siv dimmable LED units tsis hloov pauv yam tsis muaj tus thawj coj saib xyuas tsiaj txhu tau tso cai.
Qhov tseem ceeb ntawm fading
Txhawm rau kom cov noog nyob ntsiag to thoob plaws hauv kev loj hlob, lub peev xwm dimming yog qhov tseem ceeb heev. Tsis tas li ntawd, kev siv lub teeb tsis tshua muaj zog muaj qhov cuam tshuam loj rau kev siv lub zog. Lub neej ntev ntawm LED yuav cuam tshuam loj heev los ntawm kev teeb tsa lub teeb pom kev zoo, tshwj xeeb tshaj yog thaum lub sijhawm tsim khoom. LEDs kuj tsim cua sov, thiab ntev dua lawv ua haujlwm ntawm qhov kub thiab txias, qhov zoo dua. Tshwj xeeb tshaj yog nyob rau hauv huab cua kub, cov duab thiab qhov loj ntawm lub dab dej kub nyob rau hauv kev sib raug zoo nrog lub hwj chim unit yog ib qho tseem ceeb heev. Txawm li cas los xij, cov cua sov me me tau tso tawm thaum lub teeb dimmed mus rau 70 feem pua ntawm lawv lub peev xwm siab tshaj plaws, ncua lub neej ntawm qhov muag teev. Txhawm rau kom muaj peev xwm txo qis LED mus rau 70 Lux thaum lub sijhawm tsim khoom, nws yuav tsum tau dimmable thiab muaj qhov tso zis ntau tshaj plaws ntawm 100 Lux. Linear dimmers nrog 1 V intervals ua haujlwm zoo nyob rau hauv dav dav.
Cov tsev kho mob yuav tsum muaj lub teeb ntxiab nrog lub teeb txo qis> 3,000,000 kom tsim qhov tsaus ntuj tiag tiag ntawm 0.1 Lux txhawm rau txhim kho poj niam lub teeb rhiab heev. Lub teeb siv ntawm 1.5 mus rau 2 Lux ntsuas hauv qab lub teeb yuav tsum tau nyob thoob plaws hauv lub sijhawm 8- teev lub teeb ci. Yuav kom muaj txhua tus poj niam thiab cov txiv neej ntawm tib tus qauv Lux thoob plaws hauv kev loj hlob, qhov zoo ntawm lub teeb tawg yog qhov tseem ceeb. Kev sib deev homogeneity ntawm cov txiv neej thiab poj niam thaum muaj hnub nyoog 22 txog 23 lub lis piam yuav raug cuam tshuam los ntawm kev muaj cwj mem hauv tsev nrog qhov sib txawv ntawm lub teeb.
Noog lub qhov muag yog rhiab rau lub teeb thiab xim.
Tib neeg ob lub qhov muag siv sijhawm ntev los kho qhov kaj thiab qhov tsaus ntuj tshaj qhov muag avian. Lub sij hawm thiab kwv yees ntev npaum li cas nws yuav siv sij hawm los faib khoom noj ntawm cov saw hlau yog qhov tseem ceeb thaum ua nws hauv qhov tsaus ntuj. Tom qab cov khoom noj tau ncig, tsis txhob tso lub teeb tawm ntev dhau vim tias qee tus poj niam uas twb tau tso rau pem hauv ntej ntawm lub feeder lem nyiam haus ntau dua. Cov poj niam no muaj lub caij nyoog zoo dua ntawm kev noj zaub mov ntau dua li lawv cov khub txij li lawv paub tias qhov twg yog qhov twg thiab tuaj yeem noj hauv qhov tsaus ntuj. Tsis tas li ntawd, piv rau tib neeg, noog muaj ntau qhov kev xav ntawm lub teeb thiab xim. Vim li no, nws yog ib qho tseem ceeb uas cov neeg ua hauj lwm uas ua haujlwm hauv cov tsev nyob yuav tsum hnav cov khaub ncaws uas muaj xim tib yam.
Cov yam ntxwv ntawm LED technology
Hloov koj lub Lux meter nrog lub teeb pom kev zoo LED lossis sib piv cov ntawv nyeem ntawm koj lub Lux meter thiab LED meter los txiav txim seb puas muaj qhov tsis sib xws. Table 1 qhia tau hais tias, feem ntau hais lus, LED Lux meters qhia lub teeb siv ntau dua. Lumen kev saib xyuas kuj tseem ceeb heev thiab tso siab rau lub caliber ntawm lub teeb uas koj xaiv.
tshwj xeeb LED teeb pom kev zoo rau qaib
Tshwj xeeb LED qhov muag teev rau cov nqaij qaib sector nyuam qhuav tsim, thiab lawv yog tus nqi tsim nyog. Lawv koom tes nrog PSU (Power Supply Unit) los lav tias 48V DC LED qhov muag teev tau txais qhov tsim nyog thiab ruaj khov tam sim no. Hauv ntau qhov xwm txheej, 14 m × 140 m kev sib koom ua ke lub tsev tsim khoom zes tuaj yeem raug teeb tsa nrog cov teeb pom kev zoo LED uas tuaj yeem tsim tau txog 100 Lux ntawm cov noog, PSU, thiab cov peev xwm tawm qhov dimming rau tsawg dua US $ 4000. Muab hais tias teeb pom kev zoo cues yog ua hauj lwm los ntawm tus qaib pib thiab tswj cov synthesis ntawm cov me nyuam cov tshuaj hormones, teeb pom kev zoo nyob rau hauv yug me nyuam yog ib qho tseem ceeb rau kev loj hlob kev loj hlob ntawm cov Tshuag. Kev siv teeb pom kev zoo tuaj yeem suav rau ib feem tseem ceeb ntawm pob nyiaj siv tag nrho. Xav txog kev siv lub teeb ci LED los ua kom muaj kev sib raug zoo thiab kev vam meej thaum txo cov nuj nqis.
