9. Kwatancen Fasaha da Bambanci

Babban abin da ya bambanta wannan samfurin shine kunshin EMC (Epoxy Molding Compound). Idan aka kwatanta da LED a cikin daidaitaccen PPA (Polyphthalamide) ko wasu kwandon roba, EMC yana ba da aikin zafi mafi kyau, juriya mafi girma ga zafi, da juriya mafi girma ga launin rawaya daga fallasar UV da tsufa. Wannan kai tsaye yana fassara zuwa tsayin rayuwa mai tsawo da mafi kwanciyar hankali fitar da haske akan lokaci, wanda shine mafi mahimmanci a aikace-aikacen motoci inda ake tsammanin tsawon rayuwar samfurin shekaru 10-15. Tabbatarwar AEC-Q102 tana ba da tabbacin daidaitattun tabbacin aminci a ƙarƙashin yanayin damuwa na motoci, wanda LED na kasuwanci ba sa bayarwa gabaɗaya.

10. Tambayoyin da ake yawan yi (Dangane da Takamaiman Ma'auni na Fasaha)

Tambaya: Shin zan iya tuka wannan LED a 700mA akai-akai?

A: A'a. Matsakaicin naɗaɗɗen wuta na ci gaba shine 420 mA. Ƙimar 700mA ta kasance don aikin bugun jini kawai a ƙarƙashin takamaiman yanayi (bugun jini na 10ms, aikin aiki 1/10). Ci gaba da aiki a 700mA zai wuce matsakaicin raguwar ƙarfin wuta da zafin maƙwabta, wanda zai haifar da gazawar sauri.

Tambaya: Menene ma'anar juriyar zafi na 14 °C/W?

A: Yana nufin cewa ga kowane watt na wutar lantarki da ke ɓace a cikin guntun LED, bambancin zafin jiki tsakanin guntun (maƙwabta) da wurin gwaiduwa zai ƙaru da 14°C. Misali, a 3.1V da 350mA (≈1.085W), hawan zafi daga allon zuwa maƙwabta zai kasance kusan 15.2°C (1.085W * 14°C/W).

Tambaya: Ta yaya zan zaɓi daidaitaccen kwandon ƙarfin wuta (G1, H1, da sauransu)?

A: Zaɓen ku ya dogara da ƙirar tukin ku. Idan kuna amfani da tushen madaidaicin ƙarfin wuta tare da resistor mai iyakancewa, ƙaramin kwandon ƙarfin wuta (misali, kawai H1) zai haifar da madaidaicin naɗaɗɗen wuta da haske a duk LED. Ga masu tuki na yau da kullun, kwandon ƙarfin wuta ba shi da mahimmanci ga aiki amma yana iya shafar amfani da wutar lantarki kaɗan.

11. Misalin Ƙira na Ainihi

Yi la'akari da ƙira fitilar taswira ta cikin mota. Bukatar ita ce don hasken fari mai laushi, mai yaɗuwa. Faɗin kusurwar kallo na digiri 120 na wannan LED yana sa ya zama zaɓi mai kyau, saboda yana iya haskaka fadin yanki ba tare da wurare masu zafi ba, yana iya kawar da buƙatar ruwan tabarau mai yaɗuwa. Mai ƙira zai zaɓi kwandon tashar haske (misali, SB don matsakaicin haske) kuma mai yuwuwa takamaiman kwandon launi (misali, VM2) don takamaiman sautin launin fari. Za a kori LED ta hanyar sauƙaƙa da'irar tuki na yau da kullun wanda aka saita zuwa 350mA. Tsarin PCB zai haɗa da shawarar ƙirar kafa na haɗin gwiwa tare da ramukan zafi waɗanda ke haɗawa da babban yanki na jan ƙarfe don zama mai yaɗa zafi, yana tabbatar da cewa zafin maƙwabta ya kasance ƙasa da 125°C yayin aiki.

12. Ka'idar Aiki

An samar da hasken fari ta hanyar amfani da hanyar juyar da phosphor. Tsakiyar na'urar ita ce guntun semiconductor wanda ke fitar da hasken shuɗi lokacin da naɗaɗɗen wutar lantarki ta wuce ta cikinsa. Wannan guntun shuɗi an lulluɓe shi da Layer na phosphor mai rawaya (ko gauraye kore da ja). Wani ɓangare na hasken shuɗi daga guntun yana sha ta hanyar phosphor, wanda sannan ya sake fitar da shi azaman haske mai tsayin tsayi (rawaya). Haɗin sauran hasken shuɗin da ba a sha ba da kuma hasken rawaya da aka fitar, idon ɗan adam yana ganin shi azaman hasken fari. Takamaiman rabo na shuɗi zuwa rawaya da nau'ikan phosphor da aka yi amfani da su suna ƙayyade daidaitaccen zafin launi (CCT) na hasken fari (misali, fari mai sanyi, fari tsaka-tsaki, fari mai dumi).

13. Trends da Abubuwan Ci Gaban Masana'antu

Halin da ake ciki a cikin fitilar LED ta motoci yana zuwa ga mafi girman ƙarfin wutar lantarki, mafi girman inganci (lumens kowace watt), da ƙara haɗawa. Kwandon yana zama ƙanƙanta yayin da yake fitar da ƙarin haske, yana ba da damar ƙira mai kyau da ƙanƙanta. Akwai mai da hankali sosai kan inganta aminci da tsawon rayuwa don biyan ka'idodin motoci, wanda ke motsa amfani da kayan haɗawa masu ƙarfi kamar EMC da yumbu. Bugu da ƙari, manyan fasali kamar fitilun mota masu daidaita tuki (ADB) da fitilun sigina masu ƙarfi suna tura haɗawar lantarki na sarrafawa kusa da ko kai tsaye tare da kunshin LED kanta.
