7.2 Abubuwan Ƙira

• Iyakancewar Ƙarfin Lantarki:Koyaushe yi amfani da resistor na jerin ga kowane anode na ɓangare (ko direba mai ƙarfin lantarki mai dorewa) don saita ƙarfin lantarki na gaba. Lissafa ƙimar resistor ta amfani da R = (Vcc - VF) / IF, inda aka ɗauki VF daga takardun bayanan a IF da ake so.
• Haɗawa da Yawa:Don nunai masu lambobi da yawa, tuƙi mai yawa shine ma'auni. Ana sauya katodis gama gari zuwa ƙasa a jere yayin da ake tuƙa anodes na ɓangaren da suka dace da tsarin wannan lamba. Ya kamata ƙimar sabunta ta kasance sama da 60 Hz don guje wa flicker da ake iya gani.
• Gudanar da Zafi:Duk da yake LEDs suna samar da ƙarancin zafi fiye da kwan fitila, dole ne a mutunta lanƙwan raguwa don ƙarfin lantarki na gaba a aikace-aikacen yanayi mai zafi don kiyaye tsawon rayuwa da haske.
• Kariya daga ESD:LEDs na AlInGaP na iya zama masu hankali ga fitar da lantarki mai tsauri. Aiwatar da matakan kulawa na ESD na yau da kullun yayin taro.

8. Kwatancen Fasaha da Bambance-bambance

Babban abin da ya bambanta LTD-5723AJS shine amfani da AlInGaP kayan akan GaAs substrate marar ganuwa. Idan aka kwatanta da tsofaffin fasahohi kamar daidaitattun LEDs ja na GaAsP (Gallium Arsenide Phosphide), AlInGaP yana ba da ingantaccen ingantaccen haske mai haske, yana haifar da haske mafi girma don ƙarfin tuƙi iri ɗaya. Launin rawaya da aka samar shima ya fi cika da tsabta. Idan aka kwatanta da LEDs fari (waɗanda galibi LEDs ne shuɗi tare da rufin phosphor), wannan nunin rawaya mai launi ɗaya ba shi da tasirin tsufa da ke da alaƙa da phosphor kuma yana ba da takamaiman tsawon zango wanda ya dace da wasu ƙa'idodin nuni. Ingantaccensa na ƙarancin ƙarfin lantarki (har zuwa 1mA) fa'ida ce mai mahimmanci akan nunai da aka ƙera da farko don ƙarfin tuƙi mafi girma.

9. Tambayoyin da ake yawan yi (Bisa Ƙayyadaddun Fasaha)

Q: Zan iya tuƙa wannan nunin da microcontroller 3.3V ko 5V kai tsaye?
A: A'a. Dole ne ku yi amfani da resistors masu iyakancewar ƙarfin lantarki na waje ko ICs direba. VF na yau da kullun shine 2.6V. Haɗa filin MCU (3.3V ko 5V) kai tsaye zai yi ƙoƙarin tuƙa ƙarfin lantarki mara iyaka ta hanyar LED, yana lalata LED da yuwuwar filin MCU.

Q: Menene manufar daidaiton ƙarfin hasken gani na 2:1?
A: Yana tabbatar da cewa a cikin na'urar guda ɗaya, ɓangaren da ya fi duhu ba zai zama rabin haske ba kamar yadda ɓangaren da ya fi haske. Wannan yana tabbatar da daidaiton gani a duk sassan lamba.

Q: Ta yaya zan fassara raguwa don ci gaba da ƙarfin lantarki na gaba?
A: A 25°C, zaku iya amfani da har zuwa 25 mA a kowane ɓangare. Idan yanayin yanayi ya tashi zuwa 85°C, matsakaicin ƙarfin lantarki da aka halatta yana raguwa. Ma'aunin raguwa shine 0.33 mA/°C. Ragewa shine (85 - 25) * 0.33 = 19.8 mA. Don haka, matsakaicin ƙarfin lantarki a 85°C zai zama 25 - 19.8 = 5.2 mA a kowane ɓangare.

10. Gabatarwar Ka'idar Aiki

Na'urar tana aiki bisa ka'idar electroluminescence a cikin haɗin p-n na semiconductor. An ƙera sassan semiconductor na AlInGaP tare da takamaiman makamashin bandgap. Lokacin da aka yi amfani da ƙarfin wutar lantarki na gaba wanda ya wuce kofa na haɗin (kusan 2V), ana shigar da electrons da ramuka a kan haɗin. Lokacin da waɗannan masu ɗaukar caji suka sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gawa na AlInGaP yana ƙayyade makamashin bandgap, wanda kai tsaye yana ƙayyade tsawon zango (launi) na hasken da aka fitar—a wannan yanayin, rawaya (~587 nm). Substrate na GaAs marar ganuwa yana taimakawa wajen nuna haske sama, yana inganta ingantaccen fitar da haske daga saman guntu.

11. Trends na Ci gaba da Mahallin

Duk da yake wannan takamaiman takardar bayanan sashe ne, tana wanzuwa a cikin faɗaɗɗen trends na masana'antu. Amfani da AlInGaP yana wakiltar ci gaba akan tsofaffin kayan LED don launuka ja-rawaya-lemu. Trends na yanzu a fasahar nunin suna matsawa zuwa mafi ingantaccen kayan, faɗaɗɗen gamut na launi, da haɗa nunai tare da hankalin taɓawa ko iyawar sadarwa. Duk da haka, don sauƙi, amintacce, ƙarancin farashi, da ƙarancin wutar lantarki na nuna lambobi, keɓantattun nunin LED mai lamba bakwai kamar LTD-5723AJS suna da alaƙa sosai kuma galibi su ne mafi dacewar mafita. Ƙirar su ta girma, tana ba da ingantaccen aminci da hanyar haɗin kai kai tsaye wanda ke buƙatar ƙananan da'irar tallafi idan aka kwatanta da mafi rikitarwa na matrix-dot ko nunin OLED.
