Unobva LEDs. Chii chingava nyore?

Nyaya ino inotsanangura kuti pave kubatana kwakaita LEDs, izvo anotonga vanofanira zvinoenderana kuti nechokwadi kwakarurama kwomudzimu namano. Variants nezvezvakanga.

Unobva LEDs. Chii chingava nyore?

Izvi duku vava chizivikanwe nevakawanda. Munhu wose anenge anzwa ari akatungamirira marambi, nemwenje, nezvishongo nezvimwewo yakajeka, anopenya mbatya uye matoyi. Vane zvakawanda uye zvakanaka zvichienzaniswa kwakajairika chiedza Mabumba, asi pane zvinhu kushanda. Saka sei Unofanira kuita kubatana kwakaita LEDs?

Nokuti kushandiswa zvakarurama mano vanofanira mukanyatsochengeta kutevera zvishomanana zvinodiwa, uye ipapo havana kukumikidza dambudziko vachava uye vachashanda kwenguva refu.

Chikurukuru - usakanganwa maviri mitemo inokosha:

1. LEDs vari semiconductor mano uye vane rimwe-nzira conductivity, kana, mune mamwe mazwi, kubatana pakati LEDs yaifanira pamwe zvakarurama polarity (sezvo kana iwe kubatanidza bhatiri havagoni kunyonganisa "+" uye "-"). Zvikasadaro, kuti akatungamirira iri kana kupiswa kana musingadi Penyesai.

2. mudziyo pehurumende ano. Chii Magetsi, hazvina zvakakodzera kutsanangura, asi kuti kukosha kwayo angava akasiyana, unofanira kuziva. The chitsama ichiyerera kuburikidza dunhu iri pakutsvaga mwero kurwisa kwayo. Ndizvowo zvinoitika kana iwe kuzarura pombi - kana iwe kurivhura zvishoma, mvura dzichayerera nhete karwizi, inoyerera pombi mvura kuramba guru; kana iwe kurivhura chose, mvura dzichayerera ndege simba, Urume nemishonga ishoma kondo.

Nokuti yakarurama uye kuramba kushanda kwakaita unofanira iyerere kuburikidza imwe ukoshi kuitika, mwero pakutsvaga zvechadenga akatungamirira. Kana pari iri guru, pakutsva chikwata. Izvi zvakafanana nokutaura kuti tichaedza kupa mvura ine kumanikidzwa kuburikidza nhete rabha hosipaipi. Kana kumanikidzwa haasi simba zvakare, mvura vachava nguva apfuure hosipaipi, uye zvose zvichava zvakanaka. Kana zvinondiremera guru, anongoti hosipaipi dzinokaroparuka. Ndizvowo zvinoitika pamwe akatungamirira. Kana magetsi akapfuudza zvandinenge kukosha, pakutsva chikwata.

Huwandu kuitika anodzora kurwisa. Zvakakodzera kuyeuka kuti zvakatungamirira chokuita kuti voltage kunobva chinogona kuitwa chete kuburikidza kurwisa. Chii, uye zvakadini nemishonga inofanira kushandiswa dzose nokushanda akatungamirira haisi nyaya ino. Kana uchida kuti mudziyo chiedza kumusoro, zvino tora kubvunza zvakamirira yakakwana kusarudzwa kurwisa. Uye zvishoma akabata pokunamatidza nokuti unobva okunze pamwe chete.

All pamusoro apa zvinoshanda nyaya unobatanidza mano kuti DC voltage panobva, kureva, mabhatiri, bhatiri kana chimwe chakadaro. Kana kuedza kubatanidza LEDs kumba network, kureva, AC voltage bhuku, zvakakodzera anowedzera kushandisa imwe rectifier diode, kukanganwa nezvazvo apo Rule 1.

Zvisinei, pangava ezvinhu kana uchida kushandisa akawanda LEDs panguva imwe chete. Muchiitiko chino, pane nzira mbiri ezvidzidzo chinodiwa ichi.

Kana uchida kuwana Somuenzaniso, zvimwe chiedza, shandisa yakafanana kubatana kwakaita LEDs. Zvadaro zvinhu zvose zvinenge zvakafanana, chete kuti voltage kunobva panguva batanidza akawanda namano. Usakanganwa kuti kubatana neimwe inofanira kuitika kuburikidza resistor.

Kana zvakakodzera kuita chinhu chakafanana nehata dzemashizha, unofanira kuva Serial kubatana LEDs. Panyaya iyi, imwe mhando mano chokuita nomumwe zvokuti akanga chokuita yapfuura kubvisa ndinoiitawo gare gare. Somugumisiro, tinowana cheni iyo ine mbiri vakasununguka miromo - akanaka uye kunaka. Uye ichi cheni ratova kuita sezvo rimwe akatungamirira, uye rinogona chokuita Via imwe resistor kuti voltage kunobva.
