Thupi la nyali yokongoletsera ya LED silitulutsa kuwala kwa ultraviolet

LED single chubu mphamvu 0.03 ~ 0.06 Watts, ntchito DC galimoto, single chubu galimoto voteji 1.5 ~ 3.5 volts, panopa 15 ~ 18 mA, kuyankha mofulumira, akhoza kugwira ntchito pafupipafupi. Pansi pa kuyatsa komweko kwa nyali zokongoletsa za LED, kugwiritsa ntchito mphamvu ndi gawo limodzi mwa magawo khumi mwa mababu a incandescent, ndi theka la machubu a fulorosenti. Akuti ku Japan ngati ma LED okhala ndi kuwala kowirikiza kawiri amagwiritsidwa ntchito m'malo mwa theka la mababu aku Japan. Nyali za incandescent ndi fulorosenti. Mafuta okwana 6 biliyoni akhoza kupulumutsidwa chaka chilichonse. Pankhani ya nyali za bridge guardrail, nyali ya fulorosenti yokhala ndi mphamvu yomweyo imakhala yoposa ma watts 40, pomwe mphamvu ya LED iliyonse ndi ma watts 8 okha, ndipo imatha kukhala yokongola.

Nyali zodzikongoletsera za tchuthi za projekiti yokongoletsera zikondwerero zimagwiritsa ntchito ma radiation amagetsi kuti atulutse kuwala, ndipo ma filaments ali ndi zovuta monga kuyaka kosavuta, kuyika kutentha, komanso kuchepetsa kuwala. Nyali ya LED ndi yaying'ono kukula kwake komanso kulemera kwake, yophimbidwa ndi epoxy resin, imatha kupirira kugwedezeka kwamphamvu kwamakina ndi kugwedezeka, ndipo sikophweka kusweka. Avereji ya moyo ndi maola 100,000. Moyo wautumiki wa chikondwerero cha LED nyali yokongoletsera thupi imatha kufika zaka 5-10, zomwe zingachepetse kwambiri mtengo wokonza nyali ndikupewa kupweteka kwa m'malo mwa nyali pafupipafupi.

Thupi la tchuthi la kuwala kwa LED silimatulutsa kuwala kwa ultraviolet, kotero sipadzakhala udzudzu wambiri kuzungulira gwero la kuwala monga nyali zachikhalidwe. Nyali zachikhalidwe zimayatsidwa ndi voteji yayikulu yomwe imatulutsidwa ndi chowongolera, ndipo sichingayatsidwe mphamvu ikachepetsedwa. Thupi la nyali yokongoletsera tchuthi likhoza kuyatsa mkati mwamtundu wina wamagetsi, ndipo kuwalako kungathenso kusinthidwa.

Ma tchipisi a LED a tchuthi chokongoletsera nyali za LED adzakalamba nthawi yakuwunikira, ndiyeno kuwala kumawola. Kawirikawiri, pakatha nthawi yogwiritsira ntchito, nyalizo zidzakhaladi zakuda pang'ono kusiyana ndi chiyambi, ndipo kuwonongeka kwapansi kungapangitse moyo wautali. Pakutentha kokwera kwambiri, kuwola kwa kuwala kwa LED kumawonjezeka pang'onopang'ono pamene kutentha kumakwera. Kutentha kwamkati kwa LED kukadutsa kutentha kwa mphambano, kuwonongeka kwa kuwala kumawonjezeka molunjika.

Kuwala kowala kwambiri kumachepetsa kutulutsa kutentha, ndipo kuchepetsa kutentha kumatha kuchepetsa kuwonongeka kwa kuwala, ndipo kutentha kwakukulu kwa mphambano kumachepetsa zofunikira zama radiator. Kusankha tchipisi tapamwamba ndiye chikondwerero chabwino kwambiri cha LED chokongoletsera thupi. Komabe, nyali zokhala ndi tchipisi ta American CREE sizingagulidwe pamtengo wina, chifukwa ndi okwera mtengo kwambiri, ndipo kusiyana pakati pa tchipisi tofanana ndi pafupifupi nthawi 10-100, ndipo kusiyana pakati pa zinthu zomalizidwa ndikokulirapo.
