Sei-chidimbu nomwe kuratidza?

Akatungamirira (kana chiedza emitting diode) chiri Manyiminya diode kuti inongorira chiedza simba ari muchimiro "photon" kana mberi nekambani. In Electronics isu vanotaura muitiro uyu electroluminescence. Ruvara chiedza chinooneka chaibwinya neDare akatungamirira ari zvinobva yebhuruu kusvika tsvuku uye pakutsvaga spectral wavelength of chaibwinya chiedza, izvo zvinozoita inotsamira nouipi siyana kuti vari kuwedzera semiconductor zvinhu panguva gadzira.

LEDs vane mikana yakawanda zvichienzaniswa nezvaiitwa Mabumba uye mwenje, uye, zvichida chinokosha ndizvo yavo saizi diki, mukurumari, akasiyana-siyana mavara, pasi mutengo uye nyore kuwanikwa, kukwanisa nyore kushamwaridzana siyana zvimwe zvigadzirwa zvinoriumba mu digitaalinen matunhu.

Asi chikuru kushandisa LEDs ndechokuti nokuda kwavo duku ukuru, vamwe vangava kusimbiswa rimwe tsindirana kwedzimba, pova anonzi-chidimbu nomwe kuratidza.

Seven-chidimbu vanoratidza ine LEDs nomwe (saka zita rayo), ari kuenda rectangle, sezvinoratidzwa nomufananidzo. Mumwe nomumwe nomwe chidimbu akatungamirira anonzi, sezvo varege kupenyerwa nokuvhenekera kwemashoko chidimbu inoumba chikamu nhamba (12 grade kana hexadecimal nhamba hurongwa). Dzimwe mukati chete pasuru akashandisa 8th okuwedzera akatungamirira. Inoshanda kuratidza grade pfungwa (DP), saka kubvumira kuratidza munhu grade chakapatsanurwa, kana vaviri kana kupfuura 7-chidimbu kuratidzirana kwakabatana pamwechete kumiririra nhamba anopfuura gumi.

Neimwe nomwe chidimbu akatungamirira kuratidza chokuita imwe nhengo kuonana ikanyanya mutsara dzinongoda zvakananga pamusoro rectangular epurasitiki chakarurama dzimba. Akatungamirira contactsGoogle akapomerawo Tags kubva g, anomiririra mumwe nomumwe chidimbu. Other contactsGoogle kuti akatungamirira zvikamu kwakabatana pamwechete uye dzinoumba zvakafanana goho.

Saka mberi kutsvetera iri vaipa akakodzera vokukurukura akatungamirira zvikamu neimwe kuitira, achaita vamwe zvikamu zvacho kuvheneka, uye vakasara vacharamba blacked panze, vachibvumira iwe kusimbisa aida hunhu template, izvo kucharatidzwa pamusoro kuratidzwa. Izvi anotibvumira kumiririra neimwe gumi grade digits 0 kuburikidza 9, ane 7-chidimbu kuratidza.

The vakawanda mhedziso iri yemanyorero kushandiswa kuziva mhando 7-chidimbu kuratidza. Mumwe zvakatungamirira sikirini ane mbiri goho connectors, mumwe unonzi "anode" uye mumwe ukuwo, anonzi "cathode". Naizvozvo-chidimbu nomwe akatungamirira chakarurama vangava nezvemarudzi maviri redunhu chokupika - vanowanzochema cathode (in qa) uye zvakafanana anode (OA).

Kusiyana izvi nezvemarudzi maviri anoratidza kuti pamasikiro OC cathodes zvose 7 zvikamu zvine chokuita zvakananga nevamwe, uye dunhu ane nevakawanda (OA) hwakabatana pakati anode kuti anodes 7 zvikamu. nematunhu Vose anoshanda sezvinotevera.

• Vanhuwo cathode (in qa) - interconnected cathodes zvose akatungamirira zvikamu rine pfungwa pamwero "0" kana chokuita GND. The nomumwe zvikamu anonyorwa zvavo anode wedzerai goho chiratidzo "mukuru" pfungwa pamwero kana pfungwa "1" kuburikidza vakaomerwa resistor kuumba mberi kutsvetera netumedu LEDs.
• Common anode (OA) - anodes zvose zvakaita zvikamu ikashandiswa uye padanho pfungwa "1." Nomumwe zvikamu zviri chinoratidza chiedza apo mumwe nomumwe remubatanidzwa ari cathode kuti zvakohwewa, musoro "0" kana chiratidzo yakaderera-mugiredhi kuburikidza unoenderana kuitika vakaomerwa resistor.

Kazhinji,-chidimbu nomwe LEDs zvinozivikanwa anode vari akakurumbira zvikuru nekuti matunhu akawanda pfungwa kungada zvakawanda ano pane anokwanisa kupa simba kunobva. Kuonawo kuti kuratidzwa nevakawanda cathode haisi zvakananga yokutsiva redunhu kuratidzira ane nevakawanda anode. NdiEzekieri - ichi kwakafanana kwebasa rinofanira LEDs ari neizvi negwara, uye nokudaro, chiedza achine hakuitiki.

Kunyange rinogona kubatwa somunhu chete kuratidzwa, chiri 7-chidimbu vanoratidza richine munhu LEDs manomwe chete pasuru, uye sezvo vakadaro, kuti LEDs vanoda kudzivirirwa pamusoro overcurrent. LEDs emit chiedza chete kana vari misha iri mberi negwara, uye uwandu chiedza chaibwinya ndiyo Proportional kune zvakananga uno. It chete kunoreva kuti akatungamirira chiedza kusimba kunowedzera anenge linearly pamwe kuwedzera kuitika. Saka, kuti vadzivise kuvadza akatungamirira, ichi zvakananga ano anofanira kudzorwa uye shoma kune ngozi ukoshi nechitarisiko vakaomerwa resistor.

Izvi chidimbu Matafura nomwe dzinonzi kunofambira mberi. A chinokosha chinetso ndiyo vakawanda nembambo vari pasuru. Kukunda kukamurwa ichi rinoshanda simba kudzora zano nomwe chidimbu kuratidza.

Seven-chidimbu chakarurama yawana mukurumbira mukuru pakati redhiyo amateurs, nekuti zviri nyore kushandisa uye nyore kunzwisisa.
