M'malo mwa "getsi Ilyich" anabwera kuwala anatsogolera

Gwero kwambiri zingamuthandize kuwala masiku awa, mosakaika, kukhala nyali LED. Ndi zina zamakono ano mankhwala, LED kuwala pang'onopang'ono abwera m'malo miyambo incandescent babu, komanso mitundu yosiyanasiyana ya zipangizo mphamvu yopulumutsa, imene msika zoweta mindandanda yamasewera kuyatsa analinso ndi posachedwapa.

A mbiri pang'ono

Kuwala umuna pa ndime ya magetsi kupyolera pn mphambano ya chipangizo michenga yopangira zida zamagetsi wakhala kuyambira pachiyambi XX atumwi. Choncho, Henry Joseph zipolopolo, anayambitsa UK 1907, amanenedwa electroluminescence tingati ndi kudutsa ndi magetsi kudzera awiri zitsulo - Karbid Kremniya, limodzi ndi chikasu, zobiriwira ndi lalanje kuwala kwa moto pa cathode lapansi. Zimene ofanana kunachitika mu 1923 ndi wasayansi Soviet Olegom Losevym (by njira, mpaka oyambirira 70s asayansi American LED nyali bwino dzina - «Losev Kuwala», kenako dzina aiwala). Koma kwenikweni kanthu ngati kupezeka siyikuperekedwa, kotero si ankafufuza zaka zambirimbiri.

Mu 1961, izo setifiketi Kutulukira ndi infuraredi, ndipo mu 1962 - ntchito mu kuwala (wofiira) osiyanasiyana anatsogolera. Kenako, Kutulukira ndi mosalekeza bwino. Motero, utachepa ndi mtengo wake. Choncho, mu 1968 pa mababu a LED, mtengowu za $ 200, koma chifukwa cha ntchito zawo zothandiza zochepa kwambiri.

Lero, nyali awa ntchito kulikonse. Kuti tichite zimenezi, LEDs zilipo ndi mitundu yonse anthu ambiri zisoti: E27, E14, GU5.3, G53, GU10, G13.

Kuwala LED bwino kuposa masiku?

magetsi LED kupereka Ubwino:

• Mkulu wowala dzuwa. Zitsanzo Zamakono za mindandanda yamasewera izi kuyatsa mu chizindikiro ichi mofanana ndi zitsulo halide ndi sodium wochuluka kumaliseche nyali.
• Low mowa mphamvu. Ndi kangapo wotsika kuposa ochiritsira magwero kuwala.
• Long moyo utumiki. Malinga ndi Mlengi ndi luso nyale anatsogolera ukhoza pa makumi maola zikwi zana limodzi. Chiwerengero cha pa wolemera m'zinthu, zambiri zimakhudza moyo wa LEDs.
• Mkulu mphamvu ndi kugwedera. Izi zimatheka chifukwa chakuti palibe tcheru zigawo makina nkhawa.
• The otsika inertia. Mosiyana ndi nyali zina, LED pafupifupi nthawi yomweyo akuyamba kuwala pa kuwala zonse. Kuwonjezera apo, iye si mantha kukakhala mphamvu.
• Mkulu zachilengedwe ubwanawe. Mosiyana ndi nyali mphamvu yopulumutsa, LEDs kuti mulibe mankhwala enaake kapena zinthu zina zoipa.

Sikutheka osanenapo chakuti koposa ziziyenda anayamba ntchito chaka chilichonse LED nyali ya galimoto. Ali ndi makhalidwe ofanana ndi LEDs kuunikira banja, iwo inakhazikitsa ndi embodiments zosiyanasiyana zipewa (H1, h3, h7, h8, h10, etc.). Iwo anaika mu mutu nyali za galimoto, osati ngati chifunga, komanso otsika ndi mkulu mtengo.

Mwina kokha drawback lomwe lili LED getsi - kukwera mtengo. Yotsika mtengo anatsogolera (LL) Ndipafupifupi 500 rubles, ndi mtengo wa mtengo kwambiri (banga) chingaopseze 5000. Ngakhale onse, monga iwo amati, ali wachibale. Ndithu utumiki moyo wa nyali LED, kuchulukitsa ndi chiwerengero cha magetsi ankadya Kungakhalenso ngakhale yopindulitsa kwambiri kuposa ntchito ochiritsira mababu kuwala.
