Tsopano tikutha kuona magetsi a LED kulikonse, Mumsewu, m'sitolo,
ku fakitale ndi ku ofesi, m'munda ndi paki...Ndipo magetsi ena a LED ali ndi ntchito yapadera ngati kuwala kwa LED komwe kumathandiza zomera kukula mwachangu ndi kuwala kwa LED komwe kumagwira ntchito yoyeretsa ndi kupha tizilombo toyambitsa matenda, kuyatsa kuwala kwa LED kunyumba kudzakhala kotetezeka panthawi ya COVID-19. Ndikumva kuti magetsi a LED ali paliponse.Nchifukwa chiyani nyali za LED zimalowa m'malo mwa nyali za Incandescent mwachangu chonchi?
Choyamba, tidziwitseni kusiyana pakati pa nyali za Incandescent ndi nyali za fluorescent, ndi nyali za LED.
● Nyali yowala kwambiri
Nyali ya incandescent imatchedwanso babu la Edison, Imagwira ntchito poyendetsa magetsi kudzera mu ulusi (tungsten, kusungunuka pa madigiri 3,000 Celsius) zomwe zimapangitsa kutentha. Chozunguliracho chimasunga kutentha kochulukirapo, zomwe zimapangitsa ulusiwo kuzizira mpaka kutentha kopitilira madigiri 2,000 Celsius. Ikayamba kuzizira, ulusiwo umatulutsa kuwala ngati chitsulo chofiira chowala. Kutentha kwa ulusiwo kukakwera, kuwalako kumawala kwambiri.
Kupatula apo, kuwala kumakhala kwachikasu kokha. Ndipo mtundu wa chinthu chomwe chili pansi pa nyali ya incandescent siwokwanira (Ra ndi wotsika kwambiri). Moyo wonse suli wautali chifukwa cha kuponderezedwa kwa ulusi wa Tungsten.
●Nyali yowala
Mfundo yake yogwirira ntchito: chubu cha nyali ya fluorescent chimangonenedwa kuti ndi chubu chotsekedwa chotulutsa mpweya. Mpweya waukulu mu chubucho ndi gasi wa argon (womwe ulinso ndi neon kapena Krypton) pafupifupi 0.3% ya mlengalenga. Ulinso ndi madontho ochepa a siliva -- kupanga nthunzi yaying'ono ya mercury. Maatomu a Mercury amapanga pafupifupi chikwi chimodzi mwa maatomu onse a gasi.
Nyali zowala bwino zili ndi ubwino wowala kwambiri (kuwirikiza kasanu kuposa mababu wamba), mphamvu yodziwikiratu yosunga mphamvu, moyo wautali (kuwirikiza kasanu kuposa mababu wamba), kukula kochepa, komanso kugwiritsa ntchito mosavuta. Kuwonjezera pa kuwala koyera, palinso kuwala kofunda. Kawirikawiri, pansi pa mphamvu yomweyo, nyali yosunga mphamvu imasunga mphamvu ndi 80% kuposa nyali yowala, ndipo nthawi yapakati ya moyo ndi yayitali kasanu ndi kawiri. 5w ndi yofanana ndi ma watts 25 a nyali zowala, ma watts 7 ndi ofanana ndi ma watts 40, ndipo ma watts 9 ndi ofanana ndi ma watts 60.
●Ma LED nyali
Ma LED amatchedwanso ma light-emitting diode. Ndi chipangizo cha solid-state semiconductor chomwe chimatulutsa mphamvu mu mawonekedwe a ma photon ndikusintha magetsi mwachindunji kukhala kuwala. Iyi ndiyo mfundo ya ma LED.
Ma LED nyali ali ndi ubwino wambiri
1. kukula kochepa
2.kugwiritsa ntchito mphamvu zochepa
3. moyo wautali
4.osakhala ndi poizoni
5.chitetezo cha chilengedwe
Nyali za LED zakula pang'onopang'ono kuyambira kukongoletsa panja ndi kuunikira kwaukadaulo mpaka kuunikira kwapakhomo.
Tsopano mutha kumvetsetsa chifukwa chake magetsi a LED ndi otchuka kwambiri, ndipo mutha kusintha nyali yachikhalidwe mwachangu. Monga kampani yopereka magetsi a LED, Germany Liper Lighting ndi kampani yopanga magetsi yomwe yakhala ikugwira ntchito bwino mumakampani opanga magetsi a LED kwa zaka zoposa 29. Kuyambira pakupanga mpaka kupanga mpaka kugulitsa, timapereka chithandizo chimodzi chokha. Tikukupemphani kuti mulankhule nafe kuti mudziwe zambiri.
