Mikanda ya Nyali ya LED Gulani Mikanda itatu ya Nyali ya LED pa Kusamvana Kwakukulu

Kusamvetsetsana koyamba, chiyembekezo cha moyo weniweni wautumiki ndi wokwera, wopanga nyali ya nyali ya LED amayembekeza kuti moyo wa nyali ya LED ufikire maola 100,000. Komabe, monga magwero onse oyambira, kuwala kwa mikanda ya nyali ya LED kwachepanso pakapita nthawi. Chifukwa chake, ngakhale nthawi yowunikira ya mikanda ya nyali ya LED ikhoza kukhala yayitali kwambiri, MTBF sikuti ndiyo yokhayo yomwe ingaganizidwe pakuzindikira moyo wautumiki. Kuwola kwa mikanda ya nyali ya LED kumakhudzidwa ndi zinthu zambiri zachilengedwe monga kutentha kwa chilengedwe, chinyezi ndi mpweya wabwino. Chikoka cha kuchepa kwanthawi yayitali chimakhudzidwanso ndi kuwongolera, kuwongolera kwa sayansi yamafuta, kuchuluka kwapano, komanso kulingalira za mapangidwe ena ambiri amagetsi. Ogulitsa ambiri angapereke zambiri kwa makasitomala pamene akugulitsa mikanda ya nyali ya LED, zomwe zimayambitsa kusocheretsa, monga moyo wautumiki wa mikanda ya nyali ya LED mu maola 100,000. Maola 100,000 apa akutanthauza kuti wopanga amayembekeza moyo wamoyo wa Kuwala kwa LED. Komabe, monga gwero lounikira, kuwala kwa nyali kumakhala ndi njira yowola pang'onopang'ono (monga kuwala kwa dzuwa, nyali zopulumutsa mphamvu). Njira imeneyi imatchedwa kuwola kwa kuwala. Chifukwa chake, ogula akagula mikanda ya nyali ya LED, ayenera kulabadira kuchuluka kwake, osagwiritsa ntchito nthawi, ndipo ogula sangayembekezere moyo weniweniwo. Kusamvetsetsa 2, gawani ngodya yeniyeni yowunikira ngati ngodya yothandiza ya mikanda ya nyali ya LED mukona yothandiza ndi ngodya yeniyeni yotulutsa kuwala. Cholinga cha mtengo wamtengo wapatali wa mphamvu ya axial mphamvu ya kuwala -emitting intensity ndi ngodya yothandiza ndi ngodya ya axial emitting axial (njira). Kuwirikiza kawiri ngodya ya theka -value angle ndiyo mawonekedwe (kapena semi-power angle) ndiye ngodya yeniyeni yowunikira. Kuchokera pakona ya theka la mphamvu ya axial chifukwa kuwala kuli kofooka kwambiri pakugwiritsa ntchito kwenikweni, sikuwerengera pakona yothandiza. Chifukwa chake, ogula ayenera kulabadira kuwunikira kwenikweni kwa chinthucho pogula zinthu. Powerengera kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito mu polojekitiyi, zimatengera mbali yeniyeni yowunikira. Kusamvetsetsa 3, kuwala kwapamwamba, kukwezera kwa mikanda ya nyali ya LED yokhala ndi mphamvu yotulutsa kuwala, ndipo mphamvu yotulutsa kuwala imatanthawuza mphamvu yotulutsa kuwala kwa chandamale cha mzere wa njira (ku cylindrical luminous pipe imatanthauza axis) Kuwala kowala ndi kandulo (CD). Chifukwa kuwala kowala kwa mikanda yamba ya LED ndi yaying'ono, mphamvu yotulutsa kuwala nthawi zambiri imagwiritsa ntchito mayunitsi. Nthawi zambiri, gwero lounikira limatulutsa kuwala kwake kupita ku chandamale cha mikanda ya nyale ya Domestic LED yokhala ndi mphamvu zosiyanasiyana. Kuchokera pakuwona momwe angagwiritsire ntchito mphamvu panthawi imodzimodziyo, yamakono ndi yofulumira, yamakono ndi yofulumira, magetsi ndi zaka za mphamvu; pompopompo imachedwa, mphamvu yamagetsi imakhala yaying'ono, kapena momwe magetsi amagwirira ntchito, mphamvu yamagetsi imakhala yochulukirapo. Pa mikanda ya nyali ya LED, mphamvuyo imakhala yokwera kwambiri, imakhala yowala kwambiri. Kutenga mikanda itatu yofiira yofiira ya LED ya Yimei Electronics monga chitsanzo, pamene kuwala kwa axial ndi 1200mcd, panopa ndi 40mA ndipo mphamvu ndi 0.48W; Zitha kuwoneka kuti mphamvu za nyali ziwiri pansi pa kuwala kwa kuwala ndizosiyana. Chifukwa chake, ogula akagula mikanda ya nyali ya LED, ayenera kulabadira kuwala kwake, osati mphamvu. Nkhaniyi imachokera ku mikanda ya nyali ya LED http://.
