10. Tambayoyin da ake yawan yi (Bisa ga Ma'auni na Fasaha)

Q: Zan iya tuka wannan LED a 30mA don ƙarin haske?

A: Matsakaicin Matsakaici don ci gaba da kwararar gaba shine 25 mA. Aiki a 30mA ya wuce wannan ƙimar, wanda zai rage dogaro da tsawon rayuwa sosai, kuma yana iya haifar da gazawa nan take. Koyaushe yi aiki a cikin iyakokin da aka ƙayyade.

Q: Wane ƙimar resistor ne ya kamata in yi amfani da shi don wadataccen wutar lantarki na 5V?

A: Amfani da Dokar Ohm: R = (V_wadata- V_F) / I_F. Tare da V_wadata=5V, V_F=2.0V (na yau da kullun), da I_F=20mA (0.02A), R = (5 - 2.0) / 0.02 = 150 Ω. Zaɓi daidaitaccen ƙimar resistor kusa da wannan (misali, 150Ω ko 160Ω) kuma tabbatar da cewa ƙimar wutar lantarki ta isa (P = I²R = 0.06W, don haka resistor na 1/8W ko 1/4W yana da kyau).

Q: Me yasa fitar da haske ke raguwa lokacin da LED ya yi zafi?

A: Wannan shine halayen asali na LED na semiconductor. Yayin da zafin jiki ke ƙaruwa, ingancin quantum na ciki yana raguwa, kuma haɗuwar da ba ta da haske tana ƙaruwa, yana haifar da ƙarancin fitar da haske don irin wannan kwararar tuƙi. An nuna wannan a cikin lanƙwasa "Ƙarfin Dangantaka da Yanayin Yanayi."

11. Harka na Aikace-aikace na Aiki

Yanayi: Ƙirar alamar matsayi mai gani don kayan aikin masana'antu.Injiniya yana buƙatar LED yellow wanda za a iya gani a sarari a cikin yanayin masana'antu mai haske. Sun zaɓi wannan LED don ƙarfin sa mai girma (4263 mcd). Sun ƙera PCB tare da ƙafar da ta dace da girman marufi. Suna amfani da direba mai daidaitaccen kwarara da aka saita zuwa 20mA don tabbatar da daidaitaccen haske da tsawon rayuwa. Suna ɗora LED a bayan ƙaramin taga mai tsabta akan panel ɗin kayan aikin. Kunkuntar kusurwar kallo na digiri 6 ya dace da wannan aikace-aikacen alamar da aka jagoranta. Sun bi shawarar yanayin gishiri na wave yayin haɗawa kuma sun tabbatar da cewa an cika yanayin ajiya kafin amfani. Sakamakon shine ƙaƙƙarfan, abin dogaro, kuma alamar matsayi mai gani sosai.

12. Gabatarwa da Ka'idar Aiki

Wannan LED yana aiki bisa ka'idar electroluminescence a cikin diode na semiconductor. Kayan guntu shine AlGaInP (Aluminum Gallium Indium Phosphide), wanda shine semiconductor mai tsaka-tsaki kai tsaye. Lokacin da aka yi amfani da ƙarfin gaba, electrons daga yankin n-type da ramuka daga yankin p-type ana shigar da su cikin yankin aiki. Lokacin da waɗannan masu ɗaukar caji suka sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gami na AlGaInP yana ƙayyade ƙarfin bandgap, wanda kai tsaye yayi daidai da tsayin tsayi (launi) na hasken da aka fitar—a wannan yanayin, yellow mai rairawayi (~589-591 nm). Ruwan tabarau na epoxy yana aiki don kare mutuwar semiconductor, siffanta fitar da haske (sakamakon kusurwar kallo na digiri 6), da haɓaka fitar da haske daga guntu.

13. Trends na Fasaha

Masana'antar LED na ci gaba da haɓaka zuwa inganci mafi girma (lumens mafi yawa a kowace watt), ingantaccen nuna launi, da ƙarin dogaro. Duk da yake wannan na'urar tana amfani da ingantaccen fasahar AlGaInP, trends a cikin babban kasuwa sun haɗa da haɓaka mafi inganci na farin LED da aka canza da phosphor da micro-LEDs don aikace-aikacen nuni. Ga LED masu launi ɗaya kamar wannan, ci gaba da haɓaka yana mai da hankali kan tura iyakokin inganci, inganta aikin zafi mai girma, da ba da damar ƙarin ƙarfin rarraba don daidaiton launi da kwarara a cikin aikace-aikace masu wahala. Ƙarfafa biyayya ga muhalli (Maras Halogen, REACH) kuma wani ci gaba ne na ci gaba da dokokin duniya suka haifar.
