Kodi Ubwino wa Nyali ya Mpira wa LED ndi Chiyani?

M'zaka zaposachedwa, msika wa LED wakwera, koma m'zaka zaposachedwa, zochitika zosiyanasiyana zakhala zikuchitika, ndipo msika wakhala ukuvutika ndi utsi. Tsopano, ndi kukhwima kwa nyali za LED, msika wayamba kusintha. Lero, ndikudziwitsani mfundo ndi mawonekedwe a nyali yatsopano ya kuwira kwa LED. Mapiritsi a mpira wa LED ndi nyali zatsopano zopulumutsa mphamvu zomwe zimalowa m'malo mwa mababu achikhalidwe. Nyali zachikhalidwe za incandescent (nyali za tungsten filament) zimadya mphamvu zambiri komanso moyo waufupi. Pansi pa chilengedwe cha chuma cholimba padziko lonse lapansi, chaletsedwa pang'onopang'ono ndi maboma a mayiko osiyanasiyana. Komabe, chifukwa chogwiritsa ntchito zinthu zambiri za heavy metal zomwe zimaipitsa chilengedwe, zimasemphananso ndi kachitidwe kambiri kakuteteza chilengedwe. Ndi chitukuko chofulumira chaukadaulo wa LED, kuyatsa kwa LED pang'onopang'ono kwakhala chisankho chabwino kwambiri pakuwunikira kwatsopano kobiriwira. LED ndi yabwino kwambiri kuposa zowunikira zachikhalidwe pamlingo wa mfundo zowala, kupulumutsa mphamvu ndi kuteteza chilengedwe. Ndi yabwino kwa unsembe ndi ntchito. Chifukwa nyali za incandescent ndi magetsi opulumutsa mphamvu amagetsi akadali ochuluka kwambiri pakugwiritsa ntchito tsiku ndi tsiku kwa anthu. Pofuna kuchepetsa zinyalala, opanga zowunikira za LED ayenera kupanga zinthu zowunikira za LED zomwe zimakumana ndi mawonekedwe omwe alipo komanso zizolowezi za anthu, kotero kuti anthu ali mkati Mutha kugwiritsa ntchito m'badwo watsopano wa zinthu zowunikira za LED popanda kufunikira m'malo mwa nyali yachikhalidwe choyambirira ndi mzere. Ndiye nyali ya mpira wa LED idayamba kukhalapo. The LED thovu mpira ntchito mawonekedwe alipo njira, ndicho doko wononga, njira socket (E26E27E14B22, etc.), ndipo ngakhale kuti akwaniritse zizolowezi za ntchito anthu. Kutengera mfundo yowala ya njira imodzi ya LED, wopanga wasintha mawonekedwe a nyali kuti apangitse kuwala kwa nyali ya nyali ya LED kukhala yofanana ndi kadontho - kuyatsa kwa nyali ya incandescent. Kutengera mawonekedwe owala a LED, mawonekedwe a kuwala kwa mpira wa LED ayenera kukhala ovuta, ndipo amagawidwa kukhala magwero owunikira, mabwalo oyendetsa, ndi zida zoziziritsira kutentha. Magawo awa a magawowa amatha kupangitsa kugwiritsa ntchito mphamvu zochepa, kukhala ndi moyo wautali, zowoneka bwino komanso zokometsera zachilengedwe za LED. Chifukwa chake, zowunikira za LED zikadali zowunikira zapamwamba kwambiri zokhala ndi ukadaulo wapamwamba kwambiri. Mkhalidwe wa zinthu 1. Kuthekera kungathe m'malo mwa nyali zopulumutsa mphamvu ndi zinthu zababu wamba zomwe zili ndi E27, E14, GU10 ndi B22. Palibe chifukwa chosinthira, palibe chifukwa chogwiritsa ntchito akatswiri kapena akatswiri kuti awerenge malangizo athu mwatsatanetsatane pofotokozera malangizo athu ogwiritsira ntchito. , DIY ikhoza kusinthidwa mosavuta kuchokera ku kuyatsa wamba kupita ku kuyatsa kwa LED. 2. Nyali zachitetezo wamba zopulumutsa mphamvu zimakhala pafupifupi 60-80 C zikagwira ntchito, ndipo kutentha kwa nyali wamba (80-120 C) kudzawotchedwa. Mapiritsi a mpira wa LED amagwiritsa ntchito mikanda ya nyali ya LED2835 ngati gwero lowunikira, lokhala ndi akatswiri oletsa kutentha. Kutentha kumakhala kochepa kwambiri (40-60 C) kuntchito. Zinthu za nyali zopulumutsa mphamvu ndi mankhwala wamba babu amagwiritsidwa ntchito mu galasi. Ndikosavuta kuswa kugundana ndi zinthu zolimba, kuwononga kosatha komanso kusapezeka. Ma Bubbles amagwiritsa ntchito zipolopolo zopangidwa mwaukadaulo, ndipo zida za zipolopolo zimagwiritsa ntchito zida za PC / acrylic die casting. Ma LED a gawo lowunikira amagwiritsa ntchito zida zapadera zolimbana ndi zivomezi ndikugwa. Lee -lens tekinoloje), ndipo choyikapo nyali chake ndi zinthu za acrylic, ngakhale zitasweka, sikophweka kuyambitsa kudula. 3. Nyali wamba yopulumutsa mphamvu yamagetsi imachokera ku 20W-100W, ndipo magetsi opulumutsa mphamvu amachokera ku 5W-65W. Ma thovu amagwiritsa ntchito LED ngati gwero lowunikira, ndipo mphamvuyo imatha kusinthidwa ndi babu wamba wa 15W-100W ndi 5W-50W yopulumutsa mphamvu ya 15W-100W. Zitha kuwonedwa kuti chiŵerengero cha mphamvu ya thovu la mpira wa LED ndi mababu amtundu wamba ndi nyali zopulumutsa mphamvu zimatha kufika pa 1:10. Mababu wamba ndi nyali zopulumutsa mphamvu ndizokwera kwambiri (80-120 C) mukamagwiritsa ntchito nyali zopulumutsa mphamvu, ndipo mawonekedwe amagetsi opulumutsa mphamvu amakhala ndi IR (infrared). Zomwe zili m'mababu wamba ndizokwera, ndipo kutentha kwakukulu kwa chilengedwe kudzawonjezeka kwambiri. Ngati kuli m’chilimwe, kudzakhala m’chilimwe. Mwachiwonekere kumawonjezera ntchito ndi nthawi ya zipangizo za firiji. Chotsatira chake ndi kuwonjezeka kwa kugwiritsa ntchito mphamvu. Ma thovuwa amagwiritsa ntchito LED ngati gwero lowunikira, pomwe mawonekedwe a kuwala kwa LED alibe zida za IR (infrared), ndipo mawonekedwe ake onse amatengera kapangidwe kaukadaulo kopangira kutentha. Kutentha nthawi ya ntchito yachibadwa ndi 40-60 C okha. Kutentha kwaiye ndi mababu wamba kuwala ndi nyali zopulumutsa mphamvu ndi otsika. Ngati ili m'chilimwe, ntchito ndi nthawi ya zipangizo za firiji zimachepetsedwa kwambiri, ndipo kusiyana pakati pa mphamvu yogwiritsira ntchito (1:10) kumaphatikizidwa ndi mphamvu yogwiritsira ntchito mphamvu. Sungani ndalama, ndipo potsiriza kusonyeza mphamvu yopulumutsa thovu. 4. Kuteteza chilengedwe mababu wamba ndi nyali zopulumutsa mphamvu zimatulutsa kuchuluka kwa ma radiation a IR (infrared) ndi UV (ultraviolet) pantchito. Kuphatikiza apo, nyali mkati mwake imadzazidwa ndi mpweya wa inert. Panthawi yopanga komanso kugwiritsa ntchito mercury ndi mpweya wina woyipa komanso kuipitsidwa kwa zinthu zikagwiritsidwa ntchito, kudzakhalanso ndi vuto linalake pa chilengedwe pakuphwanya kuwonongeka. Mabubu amagwiritsa ntchito LED ngati gwero lowunikira. Ma LED akamagwira ntchito, palibe kuwala kwa IR (infrared) ndi UV (ultraviolet) konse. Ndipo gwero la kuwala kwa LED lomwe limagwiritsidwa ntchito mu mankhwalawa liribe mpweya uliwonse wodzaza, ndipo palibe kuwonongeka kophwanyidwa, komwe sikudzakhala ndi zotsatira zoipa pa chilengedwe. Izi zikuwonetsa mbali yake yoteteza chilengedwe. 5. Mababu wamba athanzi komanso nyali zopulumutsa mphamvu zimayaka ndi cheza cha IR (infuraredi) ndi UV (ultraviolet) chifukwa cha kuchuluka kwa ntchito. Makamaka nthawi yosungira nyama, sushi, etc.), zomwe zimakhudza thanzi lake. 5.2, kuwala kwa UV, kuwonekera kwanthawi yayitali kumagwero owunikira omwe ali ndi zosakaniza zake, mtundu wa zinthu zomwe zimawunikiridwa udzasanduka woyera, monga zovala, ngale, mawotchi, zaluso, zojambula, ndi zina zambiri. Chifukwa sipekitiramu pa nthawi ntchito alibe IR (infuraredi) ndi UV (ultraviolet) cheza, alibe zotsatira zoipa pa thanzi pa ntchito. 6. Nthawi yaifupi -kuyankha Kuunikira kwanthawi zonse -kupulumutsa mphamvu kudzasintha chifukwa cha kusintha kwa kutentha kwa chilengedwe. Kutentha koyenera kwa ntchito kumakhala pakati pa 20 ndi 40 madigiri, ndipo kuwala kokhazikika m'nyengo yozizira (pa kutentha kochepa) kumafunika kugwira ntchito kwa mphindi 5 6. Nyali zonse zimagwira ntchito bwino kusiyana ndi malo otentha m'malo ozizira, ndipo kuwala kumakhala koderapo, kapena kumatsagana ndi zochitika zowala. Pokhapokha ndi kukwera kwa kutentha, kutentha pang'onopang'ono kumapangitsa kutentha kwa -35 C-80 C, kotero kuti Nthawi zambiri, palibe chifukwa choganizira kutentha kwa chilengedwe chake. 7. Moyo ndi mphamvu - kupulumutsa nyali za nyali wamba nyali ndi mphamvu yopulumutsa nyali ndi maola 1,000 ndi maola 8000 (anawerengeredwa maola 4 pa tsiku); gwero la kuwala kwa LED kwa thovuli ndi maola 50,000 (owerengedwa maola 24 patsiku)
