8. Kwatancen Fasaha da Bambance-bambance

Idan aka kwatanta da sauran fasahohin nuni da ake samu a lokacinta (da kuma irin waɗannan ƙananan na'urori na yau), manyan abubuwan da suka bambanta na LTP-2057AJD sune fasahar LED ta AlGaAs (Aluminum Gallium Arsenide)da tsawon harafi na 2.0-inch. LEDs na AlGaAs yawanci suna ba da ingantacciyar inganci da kwanciyar hankali na launin ja. Idan aka kwatanta da ƙananan (misali, 0.56") ko manyan nunin, ya dace da wani takamaiman yanki da ke buƙatar haruffa masu matsakaicin girma. Idan aka kwatanta da LCDs, yana ba da mafi kyawun kusurwar kallo, faɗin kewayon zafi, kuma baya buƙatar hasken baya, amma yana cinye ƙarin wutar lantarki don yanki mai haske iri ɗaya. Sauƙinsa da ƙarfin ƙarfinsa sune manyan fa'idodinsa akan nunin zane-zane masu rikitarwa.

9. Tambayoyin da ake yawan yi (Bisa Sigogi na Fasaha)

Q: Wane ƙarfin lantarki na direba ake buƙata?

A: Ƙarfin lantarki na gaba kowane LED yawanci 1.8-2.4V ne a 20mA. Da'irar direba da ke ba da 5V ta zama ruwan dare gama gari, ta amfani da masu rage ƙarfin lantarki. Dole ne direba ya sarrafa lokacin yawan aiki.

Q: Ta yaya zan cimma ƙayyadaddun haske na 3000 μcd?

A: Yanayin gwaji shine kololuwar halin yanzu (I_p) na 32mA a tsarin aiki na 1/16. Wannan yana nuna matsakaicin halin yanzu kowane digo na 2mA. Dole ne direban ku na yawan aiki ya ba da wannan bugun jini na musamman don cimma hasken yau da kullun.

Q: Zan iya haɗa nunin da yawa tare?

A: I, takardar bayanan ta ce yana da iya haɗawa a kwance. Wannan mai yiwuwa yana nufin ƙirar injiniyoyi tana ba da damar haɗa jiki, kuma ƙirar lantarki za ta haɗa da haɗa layukan layi da ginshiƙi da suka dace a layi daya, yana buƙatar direba mai ƙarfin halin yanzu mafi girma don layukan da aka raba.

Q: Menene bambanci tsakanin kololuwar tsawon zango da matsakaicin tsawon zango?

A> Kololuwar tsawon zango (660 nm) ita ce tsawon zango guda ɗaya inda bakan fitowa ya fi ƙarfi. Matsakaicin tsawon zango (638 nm) shine tsawon zango guda ɗaya na haske mai launi guda ɗaya wanda zai bayyana yana da launi ɗaya ga idon ɗan adam. Bambancin ya samo asali ne daga siffar faɗin bakan fitowar LED.

10. Nazarin Lamarin Ƙira da Amfani

Yanayi: Ƙirƙirar ƙirar ƙididdiga ta samarwa mai sauƙi ta lambobi 4 don wurin aiki na masana'antu.

Za a haɗa nunin LTP-2057AJD guda huɗu a kwance. Za a tsara microcontroller (misali, Arduino ko PIC) don ƙidaya bugun jini daga firikwensin. Firmware ɗin zai sarrafa canza lambar goma zuwa daidaitattun ƙirar sassa na kowane lamba. Ƙafafun I/O na microcontroller, mai yiwuwa ta hanyar jerin transistor ko takamaiman direba IC kamar MAX7219, za su yi yawan aiki ga nunin. Tsawon 2.0-inch yana tabbatar da cewa ƙidaya tana bayyana cikin sauƙi daga ƙafafu da yawa. LEDs ja na AlGaAs suna ba da babban bambanci a kan bangon masana'antu na yau da kullun. Ƙarancin matsakaicin amfani da wutar lantarki yana ba da damar kunna na'urar daga wadataccen wutar lantarki ta DC 24V da aka saba da ita a masana'antu, wanda aka rage zuwa 5V don dabaru. Faɗin kewayon zafi mai ƙarfi yana tabbatar da aiki mai aminci a cikin wuraren da ba a sarrafa yanayi ba.

11. Gabatarwa da Ka'idar Aiki

LTP-2057AJD nuni ne na tsarin matrix 5x7. Ya ƙunshi guntuwar LED ja ta AlGaAs guda 35 waɗanda aka jera a cikin grid na ginshiƙai 5 da layuka 7. Kowane LED yana a mahadar layin anode na ginshiƙi da layin cathode na layi. Don haskaka takamaiman digo, ana amfani da ƙarfin lantarki mai kyau (ta hanyar mai iyakance halin yanzu) akan ginshiƙin anode ɗin da ya dace, yayin da cathode ɗin layinsa aka haɗa shi da ƙasa (ko ƙaramin ƙarfin lantarki). Ta hanyar jeri cikin sauri (yawan aiki) ta cikin layuka da saita daidaitattun ƙirar ginshiƙi ga kowane layi, an ƙirƙiri tunanin harafi mai tsayayye. Wannan yawan aiki yana rage adadin ƙafafun sarrafawa da ake buƙata daga 35 zuwa 12 (layuka 7 + ginshiƙai 5).
