• Ma'aunin Fitar Launi (CRI): Ga farin LED, yadda suke fitar da launuka daidai gwargwado idan aka kwatanta da tushen haske na halitta. Ana buƙatar babban CRI (>90) don tallace-tallace, gidan kayan gargajiya, da hasken zama mai inganci.
• Aminci da Tsawon Rayuwa (L70, L90): Adadin sa'o'i kafin fitar da hasken LED ya ragu zuwa 70% ko 90% na ƙimar farko a ƙarƙashin ƙayyadaddun yanayi. Tsawon rai yana rage farashin kulawa.
• Daidaiton Launi da Ƙunƙuntaccen Rarraba (Binning): Kewayon bambance-bambance a cikin rukuni. Ƙunƙuntattun rukuni suna ba da mafi kyawun daidaito.

10. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

10.1 Me ake nufi da "Lokacin Rayuwa: Bita na 2" ga zanena?

Yana nufin kuna amfani da bita na biyu na bayanin ɓangaren. Ya kamata ku tabbatar da cewa duk wani zane na baya da ke amfani da Bita na 1 har yanzu yana aiki ko akwai canje-canje masu mahimmanci (misali, a cikin girma, sigogin lantarki, ko kayan) waɗanda ke buƙatar sabunta zane. Koyaushe ku koma zuwa sabon bita don sabbin zane.

10.2 Ƙimar tsawon zango ba lamba ɗaya ba ce amma rukuni (misali, 465-470nm). Wace ƙimar ya kamata in yi amfani da ita a cikin simintina na gani?

Don siminti mai ƙarfi, yana da hikima a yi la'akari da iyakar rukunin. Yi siminti a duka ƙananan da manyan iyakokin kewayon tsawon zango don tabbatar da cewa zanenku (misali, aikin tacewa, amsawar firikwensin) yana aiki a ko'ina cikin rukunin. Don ƙididdiga mai tsauri, yin amfani da tsakiyar hanya ya zama ruwan dare gama gari, amma fahimtar hankalin tsarin ga motsin tsawon zango shine mabuɗi.

10.3 Yaya muhimmanci ne sarrafa zazzabi ga wannan ɓangaren?

Yana da matuƙar mahimmanci ga duk ƙarfin LED. Matsakaicin zazzabin haɗuwa yana haifar da saurin raguwar lumen (duhu), canjin launi (motsin tsawon zango), kuma a ƙarshe, gazawa mai ban tsoro. Dole ne a bi lakatunan rage ƙimar takardar bayanai, waɗanda ke nuna matsakaicin wutar lantarki da aka yarda akan yanayin yanayi, da gaske. Daidaitaccen tsarin PCB tare da kafafun zafi da hanyoyin zafi ba zaɓi ba ne don aiki mai aminci.

11. Nazarin Lamuran Aikace-aikace na Ainihi

11.1 Nazarin Lamari: Zana Na'urar Baya mai Daidaitaccen Haske (Uniform Backlight Unit)

Kalubale: Ƙirƙirar hasken baya don nunin inci 10 tare da cikakkiyar farin launi da haske.
Hanyar Magance:

1. Rarraba (Binning): Zaɓi farin LED daga rukunin guduwar haske ɗaya da rukunin zazzabin launi da aka haɗa (CCT). Don ƙarin sarrafawa, yi amfani da LED daga rukunin samarwa ɗaya.
2. Zanen Zazzabi: Aiwatar da PCB mai tushen ƙarfe (MCPCB) don yada zafi yadda ya kamata daga jerin LED, yana hana wurare masu zafi waɗanda ke haifar da canjin launi na gida da bambancin haske.

4. Zanen Gani: Yi amfani da farantin jagorar haske (LGP) da fina-finai masu watsawa waɗanda aka inganta don tsarin radiyon sararin samaniya na LED don cimma daidaitaccen rarraba haske a ko'ina cikin saman.

Wannan lamari yana nuna haɗin kai na lantarki, zazzabi, gani, da zaɓin ɓangare (rarraba) a cikin nasarar zanen tushen LED.

12. Gabatarwa da Ka'idar Aiki

Diodes masu fitar da haske (LED) na'urori ne na semiconductor waɗanda ke fitar da haske ta hanyar wani tsari da ake kira electroluminescence. Lokacin da aka shigar da ƙarfin wutar lantarki na gaba a kan haɗin p-n na kayan semiconductor (wanda ya dogara da gallium arsenide, gallium phosphide, ko indium gallium nitride), electrons daga yankin n-type suna sake haɗuwa tare da ramuka daga yankin p-type a cikin Layer mai aiki. Wannan taron sake haɗuwa yana sakin makamashi. A cikin diode na yau da kullun, ana sakin wannan makamashi azaman zafi. A cikin LED, an zaɓi kayan semiconductor domin wannan makamashi ya fi fitowa a cikin siffar photons (ɓangarorin haske). Takamaiman tsawon zango (launi) na fitar da haske an ƙaddara shi ta hanyar ƙarfin bandgap na kayan semiconductor da aka yi amfani da shi a yankin mai aiki. Babban bandgap yana haifar da haske mafi guntu (shuɗi), yayin da ƙaramin bandgap yana haifar da haske mafi tsayi (ja).

13. Trends da Ci gaban Fasaha

Masana'antar LED tana ci gaba da haɓaka cikin sauri. Manyan trends na haƙiƙa sun haɗa da:

• Ƙara Ƙarfi da Fitar da Lumen: Ci gaba da inganta ingantaccen ƙididdiga na ciki, dabarun fitar da haske, da fasahar phosphor suna ci gaba da tura ƙarfin haske mafi girma, yana rage amfani da wutar lantarki don haskakawa.
• Ƙananan Ƙirar da Kunshewa mai Ƙarfi: Ci gaban ƙananan girman kunshin (misali, micro-LEDs, kunshin ma'auni na guntu) yana ba da damar nunin mafi girma da mafi ƙarancin mafita na haskakawa.
• Ingantaccen Ingancin Launi da Daidaito: Ci gaba a cikin kayan phosphor da algorithms na rarraba suna ba da farin LED tare da mafi girman Ma'aunin Fitar Launi (CRI) da mafi daidaitattun wuraren launi a cikin rukunin samarwa.
• Faɗaɗawa zuwa Sabbin Kewayon Tsawon Zango: Bincike akan sabbin kayan semiconductor (misali, aluminum gallium nitride don zurfin UV, mahadi daban-daban don takamaiman tsawon zango na IR) yana buɗe sabbin aikace-aikace a cikin kashe kwayoyin cuta, firikwensin, da sadarwar gani.
• Haɗawa da Hasken Hikima: LED suna ƙara haɗawa tare da direbobi, firikwensin, da guntu na sadarwa (Li-Fi, IoT) don ƙirƙirar tsarin haskakawa mai hankali, mai haɗin kai.
• Aminci da Tsawon Rayuwa: Mayar da hankali kan kimiyyar kayan aiki (misali, mafi ƙarfi abubuwan rufewa, mafi kyawun hanyoyin sadarwa na zafi) yana ci gaba da tsawaita tsawon rayuwar tsarin LED, yana rage jimlar farashin mallaka.

Waɗannan trends ana motsa su ta hanyar binciken kimiyyar kayan aiki na asali da ingantattun hanyoyin samarwa, suna haifar da ƙarin iyawa, inganci, da ɓangarorin lantarki na gani masu yawa.
