Kada a yi biredi na komawa fiye da sau biyu. Idan fiye da sa'o'i 24 suka shuɗe tsakanin ayyukan biredi, LEDs na iya tsotse danshi su lalace. Kada a yi amfani da matsin injiniya yayin dumama.

6.2 Biredi da Gyara da Hannu

Idan ana amfani da biredi da hannu, kiyaye zazzabi ƙasa da 300°C na ƙasa da daƙiƙa 3, kuma yi sau ɗaya kawai. Ba a bada shawarar gyara bayan biredi ba; idan ba za a iya kaucewa ba, yi amfani da ƙarfe mai kawuna biyu kuma tabbatar cewa halayen LED ba su shafa ba. Kada a ɗora LEDs a kan allon da ya lanƙwasa ko kuma a lanƙwasa allon bayan biredi. Ka kauce wa sanyaya da sauri.

6.3 Yanayin Ajiya

Kafin buɗe jakar aluminum: ajiye a ≤30°C, ≤75%RH har zuwa shekara ɗaya daga ranar tattarawa. Bayan buɗe: ajiye a ≤30°C, ≤60%RH kuma yi amfani da shi cikin sa'o'i 168. Idan yanayin ajiya ya wuce, gasa a 60±5°C na akalla sa'o'i 24 kafin amfani.

7. Gwajin Amincewa

LED ɗin ya yi gwajin aminci na yau da kullun bisa ga ka'idojin JEDEC:

• Komawa (260°C, 10s, 2 zagaye): 0/1 gazawa
• Zagayen Zazzabi (-40°C zuwa 100°C, 100 zagaye): 0/1 gazawa
• Girgiza Zazzabi (-40°C zuwa 100°C, 300 zagaye): 0/1 gazawa

• Gwajin Rayuwa (25°C, IF=20mA, 1000h): 0/1 gazawa

Ma'auni na gazawa: haɓakar wutar gaba >10%, komawar wutar >2x iyakar magana, ko haske<70% na ƙaramin iyakar magana.

8. La'akari da Aikace-aikace

Wannan koren LED ya dace da masu nuni na gani, maɓallai, alamomi, da hasken baya na nuni na gaba ɗaya. Saboda kusurwar kallo mai faɗi, ana iya amfani da shi a aikace-aikacen da ke buƙatar haske iri ɗaya a kan babban yanki. Masu ƙira su tabbatar da iyakance wutar ta amfani da resistor don kauce wa wuce iyakar matsayi. Gudanar da zafi yana da mahimmanci: juriya na zafi mai girma (450°C/W) yana nuna cewa ya kamata a yi la'akari da cire zafi, musamman idan ana aiki kusa da iyakar wutar. Kada a fallasa LED ga mahalli masu yawan sulfur (sama da 100ppm), mahadi na bromine/chlorine (guda ɗaya<900ppm, jimlar<1500ppm), ko mahadi masu canzawa na kwayoyin da zasu iya fitowa daga kayan haɗi. Ya kamata a kauce wa adhesives masu tururi na kwayoyin. Kariya daga fitowar lantarki ta zama dole yayin sarrafawa. Dole ne a tsara kewayawar tuƙi don ba da damar wutar gaba kawai lokacin kunnawa ko kashewa; wutar baya na iya haifar da ƙaura da lalacewa.

9. Misalan Zane

Aikace-aikace na yau da kullun: amfani da irin waɗannan koren LEDs huɗu a cikin kwamitin nuna matsayi, kowanne yana aiki da 15mA. Tare da wutar 5V, resistor 120Ω (don VF≈3.0V) zai dace. Kusurwar kallo mai faɗi tana tabbatar da ganuwa daga kowace hanya. Don haskaka ƙaramin alama, ana iya sanya LED a cikin rami mai nuni don inganta daidaituwa. Mai ƙira dole ya yi la'akari da bambancin rarraba: yin odar rukunin musamman (misali, VF=H1, WLD=E10, IV=1CG) yana tabbatar da haske da launi daidai a duk raka'a.

10. Kwatancen Fasaha

Idan aka kwatanta da koren LEDs na al'ada masu rami, wannan fakitin SMD yana bayar da ƙaramin tsayi da kuma dacewa da haɗuwa ta atomatik. Kusurwar kallo mai faɗi (140°) ya fi na yau da kullun 120°, yana sa ya fi dacewa ga aikace-aikacen nuni inda ake buƙatar ganuwa mai faɗi. Tsarin rarraba yana ba da damar sarrafa launi da haske fiye da na'urorin da ba a raba ba, yana inganta daidaituwar samfur na ƙarshe.

11. Tambayoyi da Aka Yi Yawa

Tambaya: Zan iya tuka wannan LED a 30mA na dogon lokaci?Amsa: E, amma dole ne ka tabbatar cewa zazzabin haɗuwa bai wuce 95°C ba. A iyakar wutar, juriya na zafi 450°C/W zai haifar da dumama sosai; ana bada shawarar yanki isasshen jan ƙarfe na PCB ko cire zafi.

Tambaya: Menene ainihin tsayin igiyar wannan LED?Amsa: Ya dogara da rukunin. Rukunoni masu samuwa sun kama daga 515nm zuwa 530nm. Rukunin da aka fi amfani da shi (E10) shine 520-522.5nm.

Tambaya: Yawan zagayen komawa nawa zai iya jurewa?Amsa: Mafi girma zagaye biyu. Idan fiye da sa'o'i 24 tsakanin zagaye, ana buƙatar gasa don kauce wa lalacewar danshi.

Tambaya: Shin wannan LED ya dace da amfani a waje?Amsa: Matsakaicin zazzabi na aiki shine -40°C zuwa +85°C, amma tabbatar cewa yanayin aikace-aikacen bai wuce 85°C ba. Hakanan ka kauce wa fallasa ga sulfur da danshi mai yawa ba tare da sutura mai dacewa ba.

12. Ka'idojin Asali

Fitowar haske a cikin wannan LED ya dogara ne akan haskaka lantarki na chip ɗin semiconductor na III-V mai fitar da kore (mai yiwuwa ya dogara da tsarin InGaN/GaN). Chip ɗin yana fitar da photons lokacin da electrons suka haɗu da ramuka a yankin aiki. Tsayin igiya mafi girma an ƙayyade shi ta makamashin bandgap na rijiyoyin quantum. An sami kusurwar kallo mai faɗi ta ƙirar fakitin, yawanci ta amfani da ruwan tabarau na epoxy bayyananne tare da saman sama mai lebur don watsa haske a tsarin Lambertian. Juriyar zafi ƙanƙanta yana da mahimmanci don cire zafi daga chip zuwa filayen biredi.

13. Hanyoyin Masana'antu

Hanyar a cikin SMD LEDs tana zuwa ga ƙarami fakitoci (misali, 0603, 0402) tare da inganci mafi girma da aikin zafi mafi kyau. Wannan fakitin 1.6x0.8mm yana da ƙafafu na yau da kullun (kamar girman SMD 0603). Ci gaba na gaba na iya haɗa da ƙarin ƙarami, ingantaccen daidaituwar launi, da haɗa kariyar ESD. Karɓar koren LEDs da aka canza ta phosphor don samar da haske fari yana ƙaruwa, amma wannan samfurin shine mai fitar da kore kai tsaye, wanda ya dace da aikace-aikacen monochromatic.
