Idan aka kwatanta da tsofaffin LED na rami, 19-117 yana ba da fa'idodi masu mahimmanci a cikin girman, nauyi, da dacewa don haɗawa ta atomatik. A cikin nau'in SMD Blue LED, manyan abubuwan da ke bambanta shi su ne haɗin kai na musamman na kusurwar kallo na digiri 120, tsarin rarraba da aka ayyana don daidaiton launi da haske, haɗin kai na kariya daga ESD, da ƙaƙƙarfan matakin hankali ga danshi (MSL) tare da bayyanannun jagororin sarrafawa. Ƙididdigar ESD 2000V da aka ƙayyade tana ba da ingantaccen sarrafawa fiye da yawancin LED na asali.

10. Tambayoyin da ake yawan yi (FAQ)

Q: Wane ƙimar resistor ne ya kamata in yi amfani da wannan LED?

A: Ƙimar ta dogara da ƙarfin wutar lantarkin ku (Vs) da halin yanzu na gaba da ake so (If, matsakaicin 10mA ci gaba). Yi amfani da Dokar Ohm: R = (Vs - Vf) / If. Yi amfani da matsakaicin Vf daga takardar bayanin (3.00V) don ƙirar mai ra'ayin mazan jiya wanda ke tabbatar da cewa halin yanzu baya wuce iyaka.

Q: Zan iya amfani da wannan LED a waje?

A: Kewayon zafin aiki (-40°C zuwa +85°C) yana ba da damar amfani a yawancin wuraren waje. Duk da haka, ba a ƙididdige kunshin musamman don kariya daga ruwa ko juriya ga UV ba. Don fallasa kai tsaye ga yanayi, ana buƙatar ƙarin rufi na yanayi ko akwati.

Q: Me yasa yanayin ajiya yake da mahimmanci haka?

A: Kunshin SMD na iya ɗaukar danshi daga iska. A lokacin babban zafi na sake kunnawa solder, wannan danshin na iya yin tururi da sauri, yana haifar da rabuwa a ciki ko fashewa ("gwaɓa"), wanda ke lalata LED. Hanyoyin ajiya da gasa suna hana wannan.

Q: Me ma'anar lambar kwandon shara akan lakabin?

A: Yana gaya muku takamaiman rukunin aiki na wannan reel na LED. Misali, lambar K2-Y-30 tana nuna Kwandon shara na Ƙarfin Hasken K2 (9.00-11.5 mcd), Kwandon shara na Tsayin Raƙuman Ruwa Y (470-475nm), da Kwandon shara na Ƙarfin Lantarki na Gaba 30 (2.80-2.90V). Wannan yana tabbatar da daidaito a cikin samarwar ku.

11. Misalin Aikace-aikace na Aiki

Yanayi: Zanen alamar matsayi mai ƙarancin wutar lantarki don na'urar USB.

Na'urar tana aiki daga bututun USB na 5V. Manufar ita ce nuna "wutar lantarki a kunne" tare da LED blue. An zaɓi halin yanzu na gaba na 5mA don isasshen haske da ƙarancin amfani da wutar lantarki.

Ƙididdigewa:Yin amfani da matsakaicin Vf na 3.00V don aminci: R = (5V - 3.00V) / 0.005A = 400 Ohms. Mafi kusancin ƙimar daidaitaccen shine 390 Ohms. Haƙiƙanin halin yanzu zai kasance: I = (5V - ~2.8V_typical) / 390Ω ≈ 5.64mA, wanda yake da aminci kuma yana cikin ƙa'idar. Za a sanya LED a cikin jerin tare da wannan resistor 390Ω tsakanin layin 5V da ƙasa (lura da polarity daidai). Matsayin ƙafar PCB zai dace da shimfidar ƙasa da aka ba da shawarar daga zanen kunshin.

12. Gabatarwa akan Ka'idar Fasaha

Wannan LED ya dogara ne akan tsarin semiconductor heterostructure ta amfani da Indium Gallium Nitride (InGaN) a matsayin yanki mai aiki. Lokacin da aka yi amfani da ƙarfin lantarki na gaba a kan haɗin p-n, ana shigar da electrons da ramuka cikin yankin aiki. Haɗuwarsu yana sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gami na InGaN yana ƙayyade makamashin bandgap, wanda ke da alaƙa kai tsaye da tsayin raƙuman hasken da aka fitar—a wannan yanayin, blue (~468nm). Ruwan tabarau na epoxy yana rufe guntun, yana ba da kariya ta injiniya, yana siffata fitarwar hasken haske (kusurwar digiri 120), kuma sau da yawa yana ɗauke da phosphors idan ana son samar da launi daban (kamar fari).

13. Trends na Masana'antu da Mahallin

19-117 yana wakiltar samfurin balagagge a cikin kasuwar SMD LED. Trends na masana'antu na yanzu suna mai da hankali kan yankuna da yawa bayan alamomin asali: ƙara ingancin haske (ƙarin haske a kowace watt), mafi girman matsakaicin halin tuƙi don fitarwa mai haske a cikin ƙananan fakitin, ingantaccen yin launi da daidaito, da haɗa kayan lantarki na sarrafawa (kamar direbobi na halin yanzu) a cikin kunshin LED kanta. Hakanan akwai ƙaƙƙarfan tuƙi zuwa mafi girman aminci don aikace-aikacen motoci da na masana'antu na musamman. Duk da yake wannan ɓangaren an inganta shi don amfanin gabaɗaya, sabbin tsararraki suna tura iyakoki dangane da yawan wutar lantarki, aikin zafin jiki, da fasali na wayo.
