Ndi maubwino ati omwe magwero a kuunika kwa LED akuwonetsa?

Monga m'badwo watsopano wa gwero lowunikira, gwero lamtundu wa LED limatengera magwero owunikira ozizira a LED, omwe amatha kutulutsa mitundu yosiyanasiyana malinga ndi zosowa; nthawi yomweyo, itha kupangidwanso mu-microcomputer chip, kudzera mu pulogalamu yoyang'anira, kukwaniritsa zowoneka bwino monga kukongola kwamitundu, kulumpha, kupanga sikani, ndi madzi; komanso The chiwonetsero chazithunzi cha mawonekedwe ena chitha kusintha m'malo mwa mawonekedwe ndi mawonekedwe a pixel angapo opangira mawonekedwe, ndi mawonekedwe osiyanasiyana, zolemba ndi makanema, zotsatira za makanema, ndi zina. magetsi opangira magetsi amagwiritsidwa ntchito kwambiri pantchito zowunikira maonekedwe akunja.

Mphamvu zowunikira za LED zimasiyana kwambiri ndi ma radiation otentha achikhalidwe komanso magwero amagetsi otulutsa mpweya (monga nyali za incandescent, nyali zama sodium wamkulu).

Zowunikira za LED za pakali pano zili ndi zotsatirazi pakuwunikira:

1. Kusoka kwamphamvu komanso kukana zotsatira

Kapangidwe kake ka gwero lamtundu wa LED ndikuyiyika zinthu za electroluminescent semiconductor pa chimango, kenako ndikusindikizira ndi utomoni wozungulira. Palibe chipolopolo cha galasi mu kapangidwe kake. Palibe chifukwa chofuna kupopera kapena kudzaza mpweya winawake mu chubu ngati nyali za incandescent kapena nyali ya fluorescent. Chifukwa chake, gwero la kuyatsa kwa LED limakhala ndi kukana kwakuthupi ndi kukana kwakhudzidwa, komwe kumabweretsa kupendekera, kayendedwe ndi kugwiritsa ntchito gwero la kuyatsa kwa LED.

2. Otetezeka komanso okhazikika

Kuwala kwa point point ya LED kumatha kuyendetsedwa ndi magetsi ochepa DC. Nthawi zina, magetsi opangira magetsi amakhala pakati pa 6 ndi 24 volts, ndipo magwiridwe antchito ali bwino. Ndizoyenera kugwiritsidwa ntchito m'malo a anthu onse. Kuphatikiza apo, m'malo abwino akunja, gwero lounikira lilibe kuwala pang'ono kuposa kuwala kwachikhalidwe ndipo limakhala ndi moyo wautali. Ngakhale ikatembenuzidwira pafupipafupi, mphamvu yake ya moyo sizikhudzidwa.

3. Kuchita bwino kwachilengedwe

Chifukwa gwero lazoyimira la LED silikuwonjezera mercury panthawi yopanga, sizipangitsa kuti kuipitsa kwa mercury kutayike, ndipo zinyalala zake zitha kubwezerezedwanso, kupulumutsa zinthu komanso kuteteza chilengedwe.

4. nthawi yachangu yankho

Nthawi yankho la nyali za incandescent ndi ma millisecond, ndipo nthawi yoyankhira kuyatsa ndi ma nanoseconds. Chifukwa chake, yakhala ikugwiritsidwa ntchito kwambiri pamunda wamagetsi amagetsi pamsewu ndi magetsi amoto.

5. Kusintha kowala bwino

Malinga ndi lingaliro la magwero a kuunika kwa LED, kuwala kowunikira kapena kutulutsa pang'onopang'ono kwasinthidwa bwino kuchokera pazomwe zilipo. Mphamvu yake yogwira ntchito ikhoza kukhala yayikulu kapena yaying'ono pamulingo wovomerezeka, ndipo imasinthika bwino, yomwe imayala maziko ounikira ogwiritsa ntchito ndikuwongolera kosawunikira kwa magwero a magetsi a LED.
