Cov khoom siv teeb pom kev zoo thiab kub qis Cycling Test Chamber Thiab Test Standards

LED teeb pom kev lag luam, nrog nws cov txiaj ntsig tseem ceeb xws li kev txuag hluav taws xob thiab kev ua neej ntev, tau siv dav hauv ntau yam teeb pom kev zoo. Txawm li cas los xij, rau lub sijhawm ntev, kev lag luam tsis muaj cov qauv zoo sib xws, ua rau cov khoom lag luam tsis sib xws ntawm kev ua lag luam. Nrog rau kev nrov nrov ntawm LED teeb pom kev lag luam, cov tuam txhab tsim khoom hauv tsev thiab txawv teb chaws tau ua tiav cov qauv kev sim thiab kev ntsuam xyuas rau cov khoom lag luam LED, txhawm rau ntxiv dag zog rau kev tswj hwm zoo thiab coj kev txhim kho kev noj qab haus huv ntawm kev lag luam.

High low temperature cycling test chambertau dhau los ua cov cuab yeej ntsuas kev ntseeg siab tsis tseem ceeb. BOTO tau tsom mus rau cov khoom siv kuaj ib puag ncig rau ntau tshaj 20 xyoo thiab tuaj yeem muab cov kev pabcuam customized raws li cov neeg siv khoom xav tau.

Tam sim no, muaj kev nthuav dav thoob ntiaj teb rau kev tshawb fawb tus qauv hauv LED teeb pom kev siv thev naus laus zis. Lub National Institute of Standards and Technology (NIST) nyob rau hauv lub tebchaws United States yog nquag siv kev tshawb fawb ntawm LED kev ntsuam xyuas txoj kev, siv zog los tsim ib tug tag nrho cov kev ntsuam xyuas LED system. Lub caij no, Nyiv kuj tau tsim "White LED Testing Committee," mob siab rau kev tsim cov qauv kev sim thiab cov qauv kev qhia rau cov LEDs dawb nyob rau hauv qhov chaw kub thiab tsis kub, xws li cov lus qhia tshwj xeeb rau kev ntsuas kub qis qis.

Txhawm rau txeeb qhov siab tshaj plaws ntawm kev lag luam LED thoob ntiaj teb, cov teb chaws tsim tau nqis peev ntau hauv cov txheej txheem kev teeb tsa thiab kev sim thev naus laus zis, tsom mus rau kev tshuaj xyuas cov yam ntxwv ntawm LED thiab kev ua kom zoo ntawm cov qauv kev sim. Tsis tas li ntawd, R & D lub tuam tsev ntawm ntau lub tuam txhab loj thoob ntiaj teb tau koom tes nrog cov haujlwm tseem ceeb ntawm lawv lub teb chaws thiab thoob ntiaj teb cov koom haum tsim qauv, nquag txhawb kev txhim kho cov qauv ntsuas kub thiab qis hauv cov teeb pom kev lag luam semiconductor, xws li cov kev cai rau LED qhov kub thiab txias thiab cov av noo.

Txawm li cas los xij, International Commission on Illumination (CIE) thiab International Electrotechnical Commission (IEC) tseem tsis tau tshaj tawm cov qauv kev ywj pheej tshwj xeeb rau cov khoom siv teeb pom kev zoo LED. Cov qauv uas twb muaj lawm feem ntau yog tig los ntawm cov kev sim rau cov LEDs zoo tib yam thiab cov teeb pom kev zoo rau cov teeb pom kev zoo ib txwm muaj. Qhov no qhia tau hais tias cov txheej txheem kev tsim qauv hauv LED teeb pom kev zoo yog tseem maj mam txhim kho thiab maj mam xav tau kev tshawb fawb ntau ntxiv thiab kev koom tes thoob ntiaj teb. Tam sim no lees txais cov qauv ntsuas LED suav nrog:

IEC 60747-5 Semiconductor discrete devices thiab integrated circuits (1992)

IEC 5-2 Cov khoom siv Optoelectronic-Kev faib cov yam ntxwv thiab cov ntsiab lus (1997-09)

IEC 5-3 Optoelectronic devices-Test method (1997-08)

IEC 12-3 Cov khoom siv Optoelectronic-Ntau yam qauv dawb paug rau lub teeb-emitting diodes rau zaub (1998-02)

CIE 127-1997 LED test method (1997)

CIE / ISO LED siv ntsuas tus qauv

CIE 127-1997 tus qauv, luam tawm los ntawm International Commission on Illumination (CIE) hauv 1997, thawj zaug qhia txog lub tswv yim ntawm qhov nruab nrab LED siv thiab ua qauv ntsuas cov qauv thiab ntsuas qhov ntev, tso lub hauv paus tseem ceeb rau kev ntsuas kom raug thiab ntu ntu sib piv ntawm LED kev ua tau zoo. Txawm hais tias daim ntawv no tsis yog tus qauv thoob ntiaj teb, nws tau txais los ntawm ntau lub tuam txhab tseem ceeb thoob ntiaj teb vim nws yooj yim ntawm kev ua haujlwm thiab cov txiaj ntsig kev sim siab. Txawm li cas los xij, nrog kev hloov pauv sai ntawm LED thev naus laus zis, CIE 127-1997 tsis tuaj yeem npog qee qhov kev ntsuas kev ua tau zoo tshiab, xws li kev ntsuas kev ntsuas nyob rau hauv siab thiab qis kub caij tsheb kauj vab (high low temperature cycling test chamber) thiab high temperature and humidity condition (continuous temperature and humidity test chamber).

Lub caij no, Underwriters Laboratories Inc. (UL), US cov khoom pov thawj kev nyab xeeb thiab cov qauv tsim, kuj tseem ua rau kev txhim kho cov qauv kev ntsuas kev nyab xeeb rau cov khoom siv LED. Eli Puszkar, lub taub hau ntawm UL lub teeb pom kev lag luam, tau taw qhia tias kom ntseeg tau tias cov khoom siv teeb pom kev zoo tshiab LED tuaj yeem tau txais tib theem ntawm cov pej xeem lees paub thiab kev ntseeg siab raws li cov teeb pom kev zoo ib txwm muaj, UL tau pib tsim cov kev ntsuas kev nyab xeeb tshwj xeeb. Thaum lub sij hawm tsim khoom thiab kev loj hlob theem, manufacturers yuav tsum tag nrho xav txog kev nyab xeeb kev pheej hmoo xws li hluav taws xob poob siab, hluav taws kub, thiab physiological txaus ntshai thiab muab tso rau hauv cov khoom raws li cov txheej txheem tsim.

Tuam Tshoj muaj lub teeb pom kev zoo rau cov neeg siv khoom lag luam loj thiab lub teeb pom kev zoo muaj zog, ua rau nws yog ib qho ntawm lub ntiaj teb cov chaw tsim khoom loj thiab xa tawm cov khoom siv hluav taws xob thiab cov teeb pom kev zoo. Daim ntawv thov ntawm LED teeb qhov chaw nyob rau hauv txoj kev teeb pom kev zoo yog maj mam dhau los ua ib qho tseem ceeb txoj kev loj hlob kev taw qhia rau semiconductor teeb pom kev lag luam. Tam sim no, ntau tshaj li ib puas lub tuam txhab nyob rau hauv thiab thoob ntiaj teb tau nqis peev rau hauv kev tshawb fawb thiab kev loj hlob ntawm semiconductor streetlights, tab sis feem ntau tseem nyob rau hauv me me -batch los yog mus sib hais theem thiab tseem tsis tau ua tiav loj - teev ntau lawm. Kev siv tshuab tsis muaj zog tsis tau kov yeej tag nrho, thiab cov khoom lag luam tus qauv tseem ua tsis tiav, uas tau dhau los ua qhov tseem ceeb txwv qhov loj - nplai nce qib ntawm LED txoj kev teeb.
 

BOTO tau mob siab rau muab cov cuab yeej ntsuas kev ntseeg siab thiab kev tshaj lij rau cov khoom siv teeb pom kev zoo thiab LED luminaires, suav nrog cov khoom siv ntsuas kev ua tau zoo thiab kev lees paub kev xav tau. Peb kuj tuaj yeem tsim cov kev sim ntsuas kom ua tau raws li cov kev ntsuas tshwj xeeb ntawm cov khoom sib txawv, muab ib qho kev pabcuam - nres.

Kev ntsuam xyuas cov qauv rau LED teeb pom kev zoo thiab LED luminaires koom nrog ntau yam khoom, aiming los ntsuam xyuas kev ruaj ntseg thiab ib puag ncig adaptability ntawm cov khoom. Hom kev xeem tseem ceeb suav nrog, tab sis tsis txwv rau:

High -kev ntsuas kub ntawm kev laus: xws li LED siab thiab qis kub aging chambers, LED teeb qhov chaw siab -kub aging tests, LED luminaire siab - kub aging, thiab lwm yam.

Kub thiab humidity cycling tests: xws li LED teeb qhov chaw siab kub tsis tshua muaj kev sib tw kuaj chamber, LED luminaire ntsuas kub thiab tsis tshua muaj siab, LED siab - kub thiab siab - cov av noo ntsuas, LED damp tshav kub kuaj, LED siab thiab tsis kub damp kub kuaj, thiab lwm yam.

Kev ntsuas cua sov: xws li LED luminaire thermal shock tests, LED teeb qhov chaw siab thiab qis kub ntsuas, thiab lwm yam.

Kev ntsuas kub thiab av noo tas li: xws li LED qhov ntsuas kub thiab av noo, LED ntsuas kub thiab av noo, thiab lwm yam.
