Kodi magetsi a LED ndi chiyani?Ndipo chiyambi cha mawonekedwe a nyali za LED.

Ndi chitukuko cha sayansi ndi luso, nyali za LED zalowa pang'onopang'ono m'mbali zonse za moyo wa anthu, koma abwenzi ena sadziwa zambiri za iwo.Ndi chiyaniMagetsi a LED?Tiyeni tipeze limodzi pansipa.

kuwala komwe kumatsogolera

LED ndiye chidule cha English lightemitting diode.Kapangidwe kake ndi kachidutswa kakang'ono ka electroluminescent semiconductor chuma, chomwe chimakhazikika pa bulaketi ndi guluu wasiliva kapena guluu woyera, ndiyeno amawotcherera ndi waya wa siliva, ndikuzunguliridwa ndi utomoni wa epoxy.Kusindikiza kumagwira ntchito poteteza waya wamkati wamkati, kotero kuti LED imakhala ndi kukana kwamphamvu.

Makhalidwe a magetsi a LED

1. Voltage: LED imagwiritsa ntchito magetsi otsika,

Magetsi opangira magetsi ali pakati pa 6-24V, kutengera zomwe zimapangidwa, motero ndi magetsi otetezeka kuposa kugwiritsa ntchito magetsi okwera kwambiri, makamaka oyenera malo a anthu.
2. Kuchita bwino: Kugwiritsa ntchito mphamvu kumachepetsedwa ndi 80% poyerekeza ndi nyali za incandescent zokhala ndi kuwala komweko.

3. Kugwiritsa ntchito: Ndi kakang'ono kwambiri.Chip chilichonse cha LED ndi 3-5mm lalikulu, kotero chimatha kukonzedwa kukhala zida zamitundu yosiyanasiyana ndipo ndichoyenera kumadera osakhazikika.

4. Kukhazikika: Maola 100,000, kuwola kopepuka ndi 50% ya mtengo woyamba

5. Nthawi yoyankhira: Nthawi yoyankhira nyali za incandescent ndi milliseconds, ndipo nthawi yoyankhira nyali za LED ndi nanoseconds.

6. Kuipitsa chilengedwe: palibe zitsulo zovulaza za mercury

7. Mtundu: Mtundu ukhoza kusinthidwa mwa kusintha panopa.Diode yotulutsa kuwala imatha kusintha mosavuta mawonekedwe a gulu lamphamvu ndi kusiyana kwa bandi kwa zinthuzo pogwiritsa ntchito njira zosinthira mankhwala kuti akwaniritse kuwala kwamitundu yambiri kofiira, chikasu, chobiriwira, buluu ndi lalanje.Mwachitsanzo, nyali ya LED yomwe imakhala yofiira pamene yapano ili yaying'ono imatha kusanduka lalanje, yachikasu, ndipo pamapeto pake imakhala yobiriwira pamene ikuwonjezeka.

8. Mtengo: Ma LED ndi okwera mtengo.Poyerekeza ndi nyali za incandescent, mtengo wa ma LED angapo ukhoza kukhala wofanana ndi mtengo wa nyali imodzi ya incandescent.Nthawi zambiri, seti iliyonse yamagetsi amafunikira kukhala ndi ma diode 300 mpaka 500.
