Ma LED Multilayer Electronic Sirens Ndi Oyankhula Basic Knowledge
LED Mipikisano wosanjikiza Electronic Sirens ndi Oyankhula mfundo zofunika
1: Ma LED amitundu yambiri a Electronic Sirens ndi Olankhula, kuphatikiza ma tchipisi khumi ndi awiri kapena ochulukirapo a LED, nthawi zambiri amalumikizidwa palimodzi.Kuwala kowala kwa chip chilichonse kumatsimikiziridwa ndi kukula kwa mphamvu yomwe ikudutsamo.Chifukwa cha kugwirizana kwa mndandanda, chipangizo chilichonse cha LED mkati mwa LED chidzangodutsa pakalipano, koma magetsi pa chipangizo chilichonse ndi osiyana.Kutsika kwamagetsi kwa LED kumakhala 3.4V, koma kumasiyana pakati pa 2.8V ndi 4.2V.LED ikhoza kugawidwa kuti ichepetse kusinthasintha kwa magetsi, koma izi zidzawonjezera mtengo, ndipo kutsika kwa magetsi kutsogolo kudzasinthabe ndi kutentha ndi kugwiritsa ntchito nthawi.Kuti mupereke kuwala kosasinthasintha, nyali ya LED iyenera kuyendetsedwa ndi magetsi osasunthika okhazikika.Monga njira ina yowunikira magetsi a incandescent LED, magetsi ayenera kuphatikizidwa mu nyumba ya nyali.
2: Mawonekedwe ophatikizika a LED Electronic Sirens ndi Olankhula amaphatikizapo kuyendetsa galimoto, gulu la LED ndipo amathanso kupereka dalaivala ndi chipangizo cha LED chotetezera makina ndi kuzizira kwa chipolopolo.
3: Zofunikira za driver wa LED ndizovuta kwambiri.Iyenera kukhala yopatsa mphamvu komanso ikuyenera kukwaniritsa zofunikira za EMI ndi mphamvu zamagetsi ndipo imatha kupirira zolakwa zosiyanasiyana.Chimodzi mwazofunikira kwambiri ndi kukhala ndi dimming ntchito.Chifukwa cha kusagwirizana pakati pa makhalidwe a nyali ya LED ndi chowongolera cha dimming chomwe chimapangidwira nyali za incandescent, zikhoza kuchititsa kuti zisagwire bwino.Vuto likhoza kukhala kuti liwiro loyambira limakhala pang'onopang'ono, kuthwanima, Electronic Sirens ndi Olankhula kuwunikira kosagwirizana, kapena kuthwanima pamene kuwala kusinthidwa.Kuphatikiza apo, pali zosagwirizana pakuchita kwa gawo lililonse ndi nyali za LED zotulutsa phokoso lomveka ndi zina.Izi zoyipa nthawi zambiri zimayamba chifukwa choyambitsa zabodza kapena kutseka msanga kwa wowongolera komanso kuwongolera kosayenera kwa LED pano ndi zinthu zina.
4: Pakadali pano, zinthu za LED zimati zili ndi kusiyana kwakukulu ndi moyo weniweni wautumiki.Pankhani ya zochepa kudzikundikira galimoto dera kapangidwe luso, ndi kuunika kwa mankhwala moyo kuyeza moyo weniweni wa njira, mwina kuyambitsa zolakwika.Ngakhale kukhazikika kwa mzere woyendetsa galimoto kudzakhudza mwachindunji kukhazikika kwazinthu zonse.
