Kuwala kwa LED, kapena Light-Emitting-Diodes, ndi teknoloji yatsopano.United States Department of Energyimatchula ma LED kukhala “imodzi mwa njira zamakono zogwiritsira ntchito magetsi zosawononga mphamvu kwambiri ndiponso zimene zikupita patsogolo mofulumira.” Ma LED asanduka chowunikira chatsopano chanyumba, tchuthi, mabizinesi, ndi zina zambiri.

Kuwala kwa LED kuli ndi zabwino zambiri komanso zovuta zochepa. Kafukufuku akuwonetsa kuti nyali za LED ndizopatsa mphamvu, zokhalitsa, komanso zabwino kwambiri. Kwa ogula ndi makampani, kusinthira ku ma LED kumapulumutsa ndalama ndi mphamvu.

Taphatikiza zabwino ndi zoyipa za nyali za LED. Pitilizani kuwerenga kuti mudziwe chifukwa chake kuli koyenera kusintha magetsi a LED.

Ubwino wa Kuwala kwa LED

Magetsi a LED Ndiwopatsa Mphamvu

Kuunikira kwa LED kumadziwika kuti ndikosavuta kugwiritsa ntchito mphamvu kuposa komwe kumayambira. Kuti adziwe mmene mababu amayendera mphamvu, akatswiri amayesa kuchuluka kwa magetsi amene amasanduka kutentha komanso kuchuluka kwa magetsi amene amasandulika kukhala kuwala.

Kodi munayamba mwadzifunsapo kutentha kochuluka kwa magetsi anu akuzimitsa? Ophunzira a ku Indiana University of Pennsylvania anachita masamu. Iwo anapeza kuti pafupifupi 80% ya magetsi mu mababu incandescent amasandulika kutentha, osati kuwala. Komano magetsi a LED amasintha 80-90% ya magetsi awo kukhala kuwala, kuonetsetsa kuti mphamvu zanu sizikuwonongeka.

Zokhalitsa

Kuwala kwa LED kumakhalanso nthawi yayitali. Magetsi a LED amagwiritsa ntchito zinthu zosiyanasiyana kuposa mababu a incandescent. Mababu a incandescent amagwiritsa ntchito tungsten filament yopyapyala. Ma tungsten filaments awa atatha kugwiritsidwa ntchito mobwerezabwereza, amatha kusungunuka, kusweka ndi kuwotcha. Mosiyana ndi izi, Kuwala kwa LED kumagwiritsa ntchito semiconductor ndi diode, zomwe zilibe vuto.

Zida zolimba mu mababu a LED ndizokhazikika modabwitsa, ngakhale zimakhala zovuta. Amalimbana ndi kugwedezeka, kukhudzidwa, nyengo, ndi zina.

The US. Dipatimenti ya Zamagetsi inayerekezera moyo wa mababu wamba wa mababu a incandescent, CFLs, ndi ma LED. Mababu amtundu wa incandescent amatha maola 1,000 pomwe ma CFL amatha maola 10,000. Komabe, mababu a LED adatenga maola 25,000 - ndiko kuwirikiza kawiri ndi ½ kuposa ma CFL!

Ma LED Amapereka Kuwala Kwabwino Kwambiri

Ma LED amaunikira mbali ina yake popanda kugwiritsa ntchito zowunikira kapena zowunikira. Zotsatira zake, kuwala kumagawidwa mofanana komanso kothandiza.

Kuunikira kwa LED kumatulutsanso mpweya wochepa kapena wopanda UV kapena kuwala kwa infrared. Zida zowoneka bwino za UV monga mapepala akale m'malo osungiramo zinthu zakale ndi malo owonetsera zojambulajambula zimakhala bwino pakuwunikira kwa LED.

Pamene mababu akuyandikira kumapeto kwa moyo wawo, ma LED samangotentha ngati ma incandescent. M'malo mokusiyani mumdima nthawi yomweyo, ma LED amacheperachepera mpaka atatuluka.

Wosamalira zachilengedwe

Kupatula kukhala osagwiritsa ntchito mphamvu komanso kujambula zinthu zochepa, nyali za LED ndizosavuta kuzitaya.

Magetsi amtundu wa fluorescent m'maofesi ambiri amakhala ndi mercury kuphatikiza ndi mankhwala ena owopsa. Mankhwala omwewa sangatayidwe kudzala ngati zinyalala zina. M'malo mwake, mabizinesi akuyenera kugwiritsa ntchito zonyamula zinyalala zolembetsedwa kuti awonetsetse kuti mizere ya nyali ya fulorosenti ikusamalidwa.

Magetsi a LED alibe mankhwala owopsa oterowo ndipo ndi otetezeka - komanso osavuta! - kutaya. M'malo mwake, magetsi a LED nthawi zambiri amatha kubwezeretsedwanso.

Kuipa kwa Magetsi a LED

Mtengo Wokwera

Kuwala kwa LED akadali ukadaulo watsopano wokhala ndi zida zapamwamba kwambiri. Amawononga ndalama zochulukirapo kuposa kuwirikiza kawiri mtengo wa anzawo a incandescent, zomwe zimawapangitsa kukhala okwera mtengo. Komabe, anthu ambiri amapeza kuti mtengowo umabwereranso pakupulumutsa mphamvu kwa moyo wautali.

Kutentha Kwambiri

Kuwunikira kwa ma diode kumatha kutengera kutentha komwe kuli komwe amakhala. Ngati nyumbayo magetsi akugwiritsidwa ntchito amakhala ndi kutentha kwachangu kapena kutentha kwambiri, babu ya LED imatha kuzima mwachangu.
