Polumikiza LEDs. Kodi zikhoza kukhala chosavuta?

Nkhani zimenezi zikunena mmene litsatira kugwirizana LEDs, omwe amalamulira ayenera kutsatira dongosolo kuonetsetsa ntchito zolondola zipangizo. Mitundu ya intaneti.

Polumikiza LEDs. Kodi zikhoza kukhala chosavuta?

zinthu zazing'ono izi tsopano wotchuka. Aliyense wamva za LED nyali, nyali, garlands ndi kowala zina, zovala losonyeza ndi zidole. Iwo ndi madalitso ochuluka ndiponso zabwino poyerekeza ochiritsira mababu kuwala, koma pali zinthu zina kugwiritsa ntchito. Kodi inuyo muyenera kuchita kugwirizana LEDs?

Ntchito olondola a zipangizo ayenera mosamalitsa kutsatira zofuna wamba ochepa, ndipo iwo sadzakhala kupulumutsa vuto lirilonse ndipo adzakhala kwa nthawi yaitali.

Chofunika - musaiwale awiri malamulo zofunika:

1. LEDs ndi michenga yopangira zida zamagetsi zipangizo ndi kukhala njira ya madutsidwe, kapena, mu kulankhula kwina, kugwirizana LEDs ayenera ikuchitika ndi polarity zolondola (monga pamene inu kulumikiza batire simungakhoze kusokoneza "+" ndi "-"). Apo ayi, anatsogolera mwina kutenthedwa kapena sadzakhala kuyatsa.

2. Chipangizo ankalamulira panopa. Kodi ndi magetsi, si bwino kufotokoza, koma kuti phindu lake angakhale osiyana, muyenera kudziwa. Kuchuluka likuyenderera mu dera anatsimikiza ndi muyeso wa kukana ake. Chinthu chomwecho chimachitika pamene inu kutsegula wapampopi - ngati inu kutsegula pang'ono, madzi idzayenda mtsinje woonda, ukuyenda wapampopi madzi kukana zazikulu; ngati inu kutsegula kwathunthu, madzi idzayenda amphamvu ndege, kukana madzimadzi ndi yaing'ono Kireni.

Pakuti bwino ndi mosalekeza ntchito anatsogolera ayenera ikuyenda mwa wina phindu panopa, mlingo anatsimikiza ndi maonekedwe a anatsogolera. Ngati panopa ndi chachikulu, ndi lamoto unit. Ichi ndi lofanana kuti tidzayesetsa kupereka madzi ndi kupanikiza kupyolera woonda mphira payipi. Ngati kuthamanga si amphamvu kwambiri, madzi nthawi kudutsa payipi, ndipo zonse zikhala bwino. Ngati ziri zazikulu kwambiri, kungoti payipi mkangano. Chinthu chomwecho chimachitika ndi kutsogozedwa. Ngati panopa kuposa phindu ankafunila, ndi lamoto unit.

Kuchuluka kwa panopa akulamulira kukana. M'pofunika kumbukirani kuti kugwirizana LED kuti gwero voteji zikhoza kupangidwa kokha kupyolera kukana lapansi. Ndichiyani, ndi kuchuluka kukana ayenera kugwiritsidwa ntchito wabwinobwino wa anatsogolera si nkhani imeneyi. Ngati mukufuna kuwala chipangizo, ndiye kutenga upo okwanira mu sitolo kusankha kukaniza. Ndipo kugwira pang'ono soldering kwa kulumikiza zinthu pamodzi.

Zonsezi pamwambapa lokhudza nkhani ya polumikiza zipangizo kwa DC gwero voteji, ie, mabatire, batire kapena chinachake chonga izo. Pamene akuyesera kulumikiza LEDs kwa maukonde kunyumba, ie, AC voteji gwero, m'pofunika Komanso ntchito ndi rectifier diode, musaiwale za izi pamene Rule 1.

Komabe, pangakhale vuto pamene mukufuna kugwiritsa ntchito LEDs angapo nthawi imodzi. Pankhaniyi, pali njira ziwiri kukhazikitsa zimenezi.

Ngati mukufuna Mwachitsanzo, zambiri kuunikira, ntchito kugwirizana yomweyi LEDs. Ndiye zonse ndi pafupi zofanana, koma gwero voteji nthawi yomweyo kugwirizana zipangizo zingapo. Musaiwale kuti kugwirizana aliyense wa iwo ayenera kuchitika kudzera resistor a.

Ngati m'pofunika kuchita chinachake ngati nkhata zamaluwa, muyenera siriyo kugwirizana LEDs. Pankhaniyi, yofanana zipangizo olumikizidwa kwa mzake kuti anali olumikizidwa kwa opanda yapita kuphatikiza ina. Chifukwa cha timapeza unyolo amene ali awiri ufulu malekezero - zabwino ndi zoipa. Ndipo unyolo uwu kale kumachita monga anatsogolera umodzi, ndipo akhoza chokhudzana kudzera ndi resistor kuti gwero voteji.
