Taw qhia
LED teeb pom kev lag luam tau siv dav hauv cov phiaj xwm teeb pom kev zoo vim nws cov yam ntxwv ntawm kev txuag hluav taws xob thiab lub neej ntev. Txawm li cas los xij, vim tsis muaj kev sib koom ua lag luam tus qauv, qhov zoo ntawm LED teeb pom kev zoo ntawm cov khoom lag luam tsis sib xws. Nrog rau txoj kev loj hlob sai ntawm LED teeb pom kev lag luam, lub ntiaj teb no thiab domestic tau pib tsim cov kev ntsuam xyuas thiab kev soj ntsuam cov qauv kom paub meej cov khoom zoo thiab txhawb kev noj qab haus huv ntawm kev lag luam.
Raws li txoj cai thoob ntiaj teb-kev teeb tsa
Tam sim no, kev tshawb fawb thoob ntiaj teb thiab kev tsim qauv ntawm LED teeb pom kev siv thev naus laus zis tau nce zuj zus ntxiv. Lub National Institute of Standards and Testing (NIST) yog nquag txhawb kev tshawb fawb ntawm LED teeb pom kev zoo xeem txoj kev, aiming los tsim ib tug tag nrho cov txheej txheem ntawm LED xeem txoj kev thiab cov qauv system. Nyob rau tib lub sijhawm, Nyiv kuj tau teeb tsa tshwj xeeb "White LED Test Research Committee", tsom mus rau kev txhim kho cov txheej txheem ntsuas kub thiab tsis tshua muaj siab thiab cov qauv kev qhia rau cov coj dawb siv hauv teeb pom kev zoo, xws li cov thawv ntsuas kub thiab qis. .
Txhawm rau ua txoj haujlwm tseem ceeb hauv kev lag luam LED thoob ntiaj teb, cov teb chaws tsim tau nqis peev tseem ceeb hauv cov qauv LED thiab kev sim. Cov teb chaws no tau them nyiaj tshwj xeeb rau kev xaiv cov yam ntxwv ntawm LED thiab kev kawm txog cov qauv kev sim thaum tsim cov qauv. Tsis tas li ntawd, pawg R & D ntawm ntau lub tuam txhab loj thoob ntiaj teb kuj tau koom tes nrog cov haujlwm ntawm lub teb chaws thiab thoob ntiaj teb standardization cov koom haum los koom tes txhawb txoj kev loj hlob ntawm high-temperature test standard rau semiconductor teeb pom kev zoo, xws li cov qauv ntawm LED kub kub thiab siab. humidity kuaj chav.
Txawm li cas los xij, tam sim no, International Commission on Lighting (CIE) thiab International Electrotechnical Commission (IEC) tseem tsis tau tsim cov qauv tshwj xeeb rau LED teeb pom kev zoo, thiab cov qauv uas twb muaj lawm feem ntau koom nrog cov qauv kev sim LED zoo tib yam thiab cov qauv teeb pom kev zoo cuam tshuam nrog cov teeb pom kev zoo. Qhov no qhia tau hais tias standardization nyob rau hauv lub teb ntawm LED teeb pom kev zoo yog tseem evolved thiab xav tau kev tshawb fawb ntxiv thiab thoob ntiaj teb kev koom tes los txhim kho. Tam sim no, cov qauv kev sim ntawm cov LED zoo tib yam yog:
Iec 60747-5 Discrete Semiconductor Devices thiab Integrated Circuits (1992);
IEC Discrete Semiconductor Devices thiab Integrated Circuit Components, 5-2: Optoelectronic devices - Classification Characteristics and elements (1997-09).
IEC Discrete Semiconductor Devices thiab Integrated Circuits, 5-3: Optoelectronic devices -- Test method (1997-08);
IEC Discrete Semiconductor Devices, 12-3: Optoelectronic devices - Blank Detail Standard for light-emitting diodes for display purposes (1998-02)
CIE127-1997LED Test Method (1997);
CIE/ISOLED cov qauv ntsuas lub zog.
Hauv CIE 127-1997 tus qauv muab los ntawm International Commission on Lighting (CIE) hauv xyoo 1997, lub tswv yim ntawm qhov nruab nrab lub zog rau LED lub zog kuaj tau raug npaj, thiab cov qauv kev sib koom ua ke thiab ntsuas qhov loj me tau teev tseg, uas muab lub hauv paus tseem ceeb rau qhov raug kuaj thiab sib piv ntawm LED kev ua tau zoo. Txawm hais tias CIE 127-1997 tsis yog tus qauv thoob ntiaj teb, nws yooj yim ntawm kev siv thiab muaj peev xwm los xyuas kom meej qhov tseeb ntawm cov kev xeem tau ua rau nws tau txais los ntawm ntau lub tuam txhab loj thoob ntiaj teb. Txawm li cas los xij, nrog kev txhim kho sai ntawm LED thev naus laus zis, CIE 127-1997 tus qauv ua tsis tiav los npog qee qhov kev siv thev naus laus zis tshiab tshiab, xws li kev ntsuas kub thiab av noo ib puag ncig.
Hauv kev tsim cov qauv LED, Nyiv kuj tau qhia txog kev siv zog zoo. Piv txwv li, Nyiv lub tuam txhab Nichia thiab United States Lumileds lub tuam txhab rau LED thev naus laus zis hla daim ntawv tso cai, thiab npaj yuav koom ua ke tsim lub zog LED cov qauv los txhawb kev lag luam daim ntawv thov thiab txhawb kev ruaj khov ntawm kev lag luam LED.
Tsis tas li ntawd, Tebchaws Asmeskas cov khoom pov thawj kev nyab xeeb thiab cov qauv teeb tsa lub cev UL (Underwriters Laboratories Inc.) kuj tseem ua haujlwm tsim cov qauv kev ntsuas kev nyab xeeb ntawm LED. Eli Puszkar, teeb pom kev lag luam Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam ntawm UL, tau hais tias txhawm rau kom ntseeg tau tias cov khoom siv teeb pom kev zoo tshiab tuaj yeem lees txais thiab ntseeg tau los ntawm cov pej xeem raws li cov khoom siv teeb pom kev zoo, UL tau pib tsim cov qauv kev ntsuas kev nyab xeeb rau cov khoom siv LED. Thaum lub sij hawm tsim thiab tsim cov khoom tshiab, cov neeg tsim khoom yuav tsum xav txog cov teeb meem kev nyab xeeb xws li kev tiv thaiv hluav taws xob, hluav taws kub thiab kev phom sij ntawm lub cev.
BOTO lub siab thiab tsis kub ntsuas chamber muaj lub luag haujlwm tsis tuaj yeem hloov pauv hauv qhov ntsuas kub thiab qis ntawm LED teeb, uas tuaj yeem kuaj xyuas qhov kev ntseeg tau ntawm cov khoom thiab txhim kho kev sib tw ntawm cov khoom.
BOTO tshwj xeeb hauv cov chav ntsuas kub thiab tsis kub rau ntau tshaj 20 xyoo, yog tias koj muaj lus nug thovtiv tauj peb.
