Mafala Akutoma: Chen Fumng ndi Ena Kum'mwera kwa Sayansi ndi Technology apanga daide yolumikizidwa ndi madontho ophatikizidwa pogwiritsa ntchito malo owoneka bwino a Incroden Incrode. DIODOD imatha kugwira ntchito molimbika komanso yosavomerezeka, ndikusintha kwakunja kwa 20.09% ndi 21.15%, motsatana. Kuphatikiza apo, polumikiza zida zingapo zolumikizidwa, gululi limatha kuthamangitsidwa mwachindunji ndi mphamvu yanyumba popanda kusowa kwa zovuta kumayambiriro. Pansi paulendo wa 220 v / 50 hz, mphamvu ya mphamvu ya pulagi yofiyira ndi kusewera pagawo 15.70 lm w-1, ndipo kunyezimira kosinthika kumatha kufikira 25834 cd m-2.
Kuwala Kutulutsa Maselo (Ma Fonter) akhala njira yowunikira kwambiri chifukwa cha kuchuluka kwake, kukhala ndi moyo wokhazikika, malo abwino komanso zachilengedwe komanso zachilengedwe zomwe zimachitika padziko lonse lapansi. Monga Semiconductor Pn diide, LED imatha kugwira ntchito pansi pagalimoto yotsika kwambiri (DC). Chifukwa cha jakisoni wosagwirizana komanso wosalekeza, zolipiritsa zotenthetsera, potero zimachepetsa kukhazikika kwa ntchito yatsogozedwa. Kuphatikiza apo, magetsi apadziko lonse lapansi amatengera kusintha kwa magetsi kwambiri, ndipo zida zambiri zapakhomo monga kuwala sizingagwiritse ntchito magetsi kwambiri. Chifukwa chake, pamene LED imayendetsedwa ndi magetsi osintha, otembenuka owonjezera a AC-DC amafunikira kuti akhale mgulu lazosintha mphamvu yamagetsi kukhala mphamvu yamagetsi yotsika. Chosinthira wamba cha AC-DC chimaphatikizapo tradermer kuti muchepetse magetsi a magetsi ndi madera oyambira kukonza ma ac. Ngakhale kusintha kwa kusintha kwa otembenuka ambiri a AC-DC ikhoza kufika pa 90%, pamakhala mphamvu yamphamvu pakusintha. Kuphatikiza apo, kusintha kunyezimira kwa LED, dera lodziletsa liyenera kugwiritsidwa ntchito kuwongolera magetsi a DC ndikupereka zomwe zilipo pazomwe zidalipo (onani chithunzi 1b).
Kudalirika kwa dera loyendetsa kumadzakhudza kukhazikika kwa magetsi a LAD. Chifukwa chake, kudziwitsa otembenukira kwa AC-DC ndi madalaivala oyendetsa bwino okha (awerengera pafupifupi 17% ya mtengo wonse wa LED), komanso kumawonjezera kukhazikika kwamphamvu ndikuchepetsa kukhazikika kwa nyali za adatsogolera. Chifukwa chake, kukulitsa ma Entrofinescent (El) zida zomwe zingayendetse mwachindunji ndi magetsi 110 v / 220 h / 60 hz popanda kufunikira kwa zida zamagetsi ndizofunikira kwambiri.
M'zaka makumi angapo zapitazi, angapo act electroctinescent (zida za AC-El) zawonetsedwa. Mbale yamagetsi wamba imafanana ndi ufa wa fluorescent yotulutsa chosanjikiza pakati pa zigawo ziwiri zokwanira (Chithunzi 2A). Kugwiritsa ntchito mawu otchinga kumalepheretsa jakisoni wakunja kwaonyamula, ndiye kuti palibe chowongolera mosamala kudzera pa chipangizocho. Chipangizocho chimagwira ntchito ya capakoritor, komanso pansi pa gawo lamagetsi la Acs, ma elekitirons amapangidwa mkati amatha kulowa mu malo olandana kuti atuluke. Nditapeza mphamvu zokwanira za kinetic, ma elekitirons amalumikizana ndi luminescent Center, kutulutsa zopindika ndi kutulutsa kuwala. Chifukwa cholephera ku jekeseni kuchokera kunja kwa ma electrodes, kunyezimira komanso kuchita bwino kwa zinthu izi ndizotsika kwambiri, zomwe zimalepheretsa ntchito zawo m'minda yowunikira ndikuwonetsa.
Pofuna kukonza magwiridwe ake, anthu apanga ma ballast aclestics osanjikiza ac okhala ndi osanjikiza amodzi (onani Chithunzi chowonjezera 2b). Mu kapangidwe kake, mkati mwa theka la ma ac drive, onyamula mlandu amalowetsedwa mwachindunji kuchokera ku elekisi yochokera kunja; Kubwezeretsa koyenera kumatha kuwonedwa ndi kubwezeretsanso ndi mtundu wina wa onyamula mkati. Komabe, mkati mwa theka la ma ac drive, onyamula omwe avalidwewo adzamasulidwa ku chipangizocho chifukwa chake sichingapangitse kuwala kochepa komwe kumangoyendetsa pang'ono. Kuphatikiza apo, chifukwa cha mapangidwe a zidayi, magetsi amapangira zida zonse za ma ac ndi pafupipafupi, ndipo zimapangitsa kuti zikhale zovuta kuti zizigwirizana ndi ma ailfép angapo, omwe amawapangitsa kukhala ovuta kukhala ogwirizana ndi mauna otsika (50 hertz / 60 hertz).
Posachedwa, wina anaganiza za chipangizo chamagetsi chomwe chimatha kugwira ntchito pa 50 hz / 60 hz. Chipangizochi chimakhala ndi zida ziwiri zofananira za DC (onani Chithunzi 2C). Ndi magetsi ofupikirapo ma elekitiki apamwamba a zida ziwirizo ndikulumikiza ma elekitor a curlanar ku gwero lamphamvu, zida ziwirizi zitha kuzimiririka. Kuchokera pamalingaliro ozungulira, chipangizo cha AC-DC chimapezeka polumikiza chipangizo chamtsogolo komanso chida chosinthira. Chida chopita patsogolo, chipangizo chosinthiracho chimazimitsidwa, ndikuchita ngati kukana. Chifukwa cha kupezeka kwa kukana, magetsi othandizira amakhala ochepa. Kuphatikiza apo, zida zopepuka za AC imangogwiritsa ntchito voliyumu yotsika ndipo sizingaphatikizidwe mwachindunji ndi 110 V / 220 V ingasinthe magetsi. Monga taonera mu tebulo lowonjezera lachitatu ndi lowonjezera 1, magwiridwe antchito (owala ndi magetsi) a zida zamphamvu za AC-DC zomwe zimayendetsedwa ndi zida zapamwamba kuposa zida za DC. Pakadali pano, palibe chida champhamvu cha AC-DC chomwe chimathamangitsidwa mwachindunji ndi magetsi pa 110 v / 220 v, 50 hz / 60 hz, ndipo ali ndi moyo wautali.
Chen Fumng ndi gulu lake kuchokera ku yunivesite yakumwera ya sayansi ndi ukadaulo wapanga ma dadi olumikizidwa a DOT omwe amagwiritsa ntchito ma elekion omwe amachititsa kuti ma elekiti apakatikati. DIODOD imatha kugwira ntchito molimbika komanso yosavomerezeka, ndikusintha kwakunja kwa 20.09% ndi 21.15%, motsatana. Kuphatikiza apo, polumikiza zida zingapo zolumikizidwa, gululi limatha kuthamangitsidwa mwachindunji ndi mphamvu yanyumba popanda kuvuta kwa mabwalo ofiira. Pulogalamu yopangidwa ndikusewera ma seti a LOT imatha kupanga zachuma, zokhazikika, zowoneka bwino, komanso zokhazikika, komanso zokhazikika.
