Ƙunƙun rarrabawa don matsakaicin tsawon tsawon (±1nm a cikin kwandon AA/AB) siffa ce mai mahimmanci don aikace-aikacen da ke buƙatar daidaiton launin shudi a cikin raka'a da yawa, kamar a cikin nuni na LED da yawa ko tsararrun hasken baya. Masu ƙira ya kamata su ƙayyade kwandon tsawon tsawon da ake buƙata don tabbatar da daidaiton gani.

9. Kwatance da Jagorar Zaɓi

Lokacin zaɓar SMD LED, mahimman sigogi don kwatanta sun haɗa da: ƙarfin hasken gani/ƙarfi (don haske), kusurwar kallo (don yaduwar katako), ƙarfin lantarki na gaba (don ƙirar direba), matsakaicin tsawon tsawon (don launi), da girman fakitin. Wannan takamaiman LED yana ba da haɗin kai mai daidaito na matsakaicin haske, faɗin kusurwar kallo sosai, da daidaitattun launin shudi a cikin fakitin SMD na gama-gari, yana mai da shi zaɓi mai fa'ida don nuni na yanayi. Don buƙatun haske mafi girma, za a zaɓi na'ura daga kwandon ƙarfin hasken gani mafi girma (T1, T2). Don ƙarancin amfani da wutar lantarki, na'ura tare da ƙaramin kwandon VF (D6, D7) tare da mai iyakance halin yanzu da ya dace zai yi amfani.

10. Tambayoyin da ake yawan yi (FAQs)

Q: Zan iya tuƙi wannan LED kai tsaye daga fil ɗin dabaru na 5V?

A: A'a. Matsakaicin ƙarfin lantarki na gaba yana kusan 3.0V, kuma wadata na 5V zai haifar da halin yanzu mai yawa, wanda zai iya lalata LED. Dole ne ku yi amfani da mai iyakance halin yanzu ko da'irar direba na halin yanzu na akai-akai.

Q: Menene bambanci tsakanin Ƙarfin Hasken Gani (lm) da Ƙarfin Hasken Gani (mcd)?

A: Ƙarfin Hasken Gani yana auna jimlar ƙarfin hasken da ake iya gani a kowane bangare. Ƙarfin Hasken Gani yana auna haske a takamaiman shugabanci (yawanci axis na tsakiya). Takardar bayani na wannan LED tana ba da duka biyun, tare da ƙarfin kasancewar ƙimar tunani da aka samo. Faɗin kusurwar 120° yana nufin ƙarfin axial (mcd) ya yi ƙasa da LED mai ƙunƙuntaccen kusurwa tare da jimlar ƙarfi ɗaya (lm).

Q: Me yasa danshin ajiya yake da mahimmanci haka?

A: SMD LEDs na'urori ne masu kula da danshi. Danshin da aka sha zai iya yin tururi da sauri yayin tsarin haɗa reflow mai zafi, yana haifar da rabuwa na ciki, tsagewa, ko "popcorning," wanda ke haifar da gazawa. Takamaiman yanayin ajiya da rayuwar bene (sa'o'i 168) suna hana wannan.

Q: Shin wannan LED ya dace da amfani a waje?

A: Kewayon zafin aiki ya kai -40°C zuwa +85°C, wanda ya ƙunshi yawancin yanayi na waje. Duk da haka, dogon bayyanar da hasken rana kai tsaye (UV), shigar danshi, da zagayowar zafi fiye da ƙayyadaddun iyakoki na iya lalata ruwan tabarau na epoxy da rage tsawon rayuwa. Don mawuyacin yanayi na waje, ya kamata a yi la'akari da LED ɗin da aka ƙididdige su musamman don irin wannan amfani.
