3mm Ta hanyar rami LED Red Diffused LED Babban Haske

Red diffused LED tare da daidaitaccen siffa & babban haske

Idan hasken 3 0 4 R D ba zai iya biyan abin da ake buƙata ba, da fatan za a duba tare da wannan ； 304NRD.

Wannan ja ta cikin ramin LED ya sami matakin haske a kan babban haske, wanda ya fi girma kaɗan fiye da 304RD. Lokacin amfani da wannan 3mm ja ta cikin ramin LED a cikin 20mA, haske zai iya kaiwa 200-400mcd. Zai zama 100-200mcd kawai don 304RD. Kwatanta da 304R D, wannan 304NRD ya fi cikakke don yin aiki akan aikin haske na LED b ack ko fitilun kayan ado na LED. Idan kuna neman wasu 3mm LED tare da babban haske, da fatan za a duba tare da wannan fitilun LED.

Girman 3mm ta cikin ramin LED:

Hanyoyin LED ta rami:

Hanyoyin Hanya na Lantarki (Tc = 25 ℃ )

*θ1/2 kusurwar kashe-sxis ce inda ƙyalli mai haske shine rabin ƙarfin axia mai haske;

Babban aikace -aikacen:

* Mafi dacewa don hasken baya;

* Hasken nuni;

* Fitilar ado na LED;

Ci gaban masana'antu na ramin LED:

Kwatanta da SMD LED, samar da ramin LED zai zama mafi rikitarwa. Wanda ke nufin zai ɗauki ƙarin ci gaban samarwa da lokacin samarwa:

Da farko, muna buƙatar shirya guntu na LED (wannan zai zama daidai da samar da LED na SMD ); Abu na biyu, za mu buƙaci sanya guntu na LED a cikin firam ɗin LED, sannan za mu buƙaci tsattsarkar zinare don haɗa cathode da anode na firam ɗin LED. Akwai daban -daban, Don samar da LED na SMD, muna buƙatar sanya epoxy zuwa firam ɗin LED kuma jira har sai ta bushe ta tanda. Koyaya, don fitilun LED, muna buƙatar shigar da epoxy a cikin ƙirar ruwan tabarau kuma sanya duk abubuwan a cikin tanda na aƙalla awanni 8 har sai sun bushe. Bayan haka, muna buƙatar cire su daga tanda kuma fitar da LED daga ƙirar. Sannan muna buƙatar yanke fil ɗin LED don su kasance masu sauƙin gwaji.

A ƙarshe, mun sami LED. Don tabbatar da inganci da suttura kamar yadda ake buƙata. Hakanan muna buƙatar sanya duk LED ɗin a cikin injin rarrabuwa kuma su zamu sami LED tare da akwatuna iri ɗaya.
