A zamanin yau, LED ya zama wani ɓangare na rayuwarmu wanda ba za a iya shiga ba. A yau, zan ba ku taƙaitaccen bayani game da manufar, halaye, da rarrabuwa.

Manufar LED

LED (Light Emission Diode) na'urar semiconductor ce mai ƙarfi wadda ke canza wutar lantarki kai tsaye zuwa Haske. Zuciyar LED ɗin guntu ce ta semiconductor, tare da ƙarshenta ɗaya a kan maƙallin, ɗayan ƙarshenta kuma electrode ne mara kyau ne, ɗayan kuma an haɗa shi da ƙarshen wutar lantarki mai kyau, don haka dukkan guntu ɗin an haɗa shi da resin epoxy.

Guntuwar semiconductor ta ƙunshi sassa biyu, ɗaya daga cikinsu semiconductor ne mai nau'in p, wanda ramuka suka mamaye, ɗayan kuma semiconductor ne mai nau'in n, wanda electrons ke mamaye shi. Amma idan aka haɗa semiconductor guda biyu, "haɗin pn" ya haɗu a tsakaninsu. Lokacin da aka shafa wutar lantarki a guntu ta hanyar waya, ana tura electrons zuwa yankin p, inda suke haɗuwa da ramin kuma suna fitar da makamashi a cikin siffar photons, wanda shine yadda LEDs ke haskakawa. Kuma tsawon hasken, launin hasken, ana ƙayyade shi ta hanyar kayan da ke samar da haɗin PN.

Halayen LED

Halayen asali na LED suna tabbatar da cewa shine mafi kyawun tushen haske don maye gurbin tushen haske na gargajiya, yana da aikace-aikace iri-iri.

• Ƙaramin Ƙarami

LED a zahiri ƙaramin guntu ne da aka lulluɓe shi da resin epoxy, don haka ƙarami ne kuma mai sauƙi.

-Ƙarancin Amfani da Wutar Lantarki

Yawan amfani da wutar lantarki ta LED yana da ƙasa sosai, gabaɗaya, ƙarfin wutar lantarki na LED shine 2-3.6V.
Wutar lantarki mai aiki shine 0.02-0.03A.
Wato, ba ya cin wutar lantarki fiye da 0.1W.

• Dogon Rayuwar Sabis

Da madaidaicin wutar lantarki da ƙarfin lantarki, LEDs na iya samun tsawon rai har zuwa awanni 100,000.

• Haske Mai Girma da Ƙananan Zafi

• Kare Muhalli

Ana yin fitilun LED da kayan da ba su da guba, ba kamar fitilun fluorescent ba, waɗanda ke ɗauke da sinadarin mercury kuma suna haifar da gurɓatawa. Haka kuma ana iya sake yin amfani da su.

• Mai ƙarfi da ɗorewa

An lulluɓe LEDs gaba ɗaya a cikin resin epoxy, wanda ya fi ƙarfin kwararan fitila da bututun fluorescent. Haka kuma babu sassan da suka lalace a cikin fitilar, wanda ke sa LEDs ɗin ba za a iya lalata su ba.

Rarraba LED

1, Dangane da bututun fitar da haskelaunimaki

Dangane da launin hasken bututun fitar da haske, ana iya raba shi zuwa ja, lemu, kore (da kore mai launin rawaya, kore mai kyau da kore mai tsarki), shuɗi da sauransu.
Bugu da ƙari, wasu LEDs suna ɗauke da guntu masu launuka biyu ko uku.
Dangane da diode mai fitar da haske wanda aka gauraya ko ba a gauraya shi da masu watsawa ba, masu launi ko marasa launi, launuka daban-daban na LED ɗin da ke sama za a iya raba su zuwa launuka masu haske, marasa launi, masu watsawa masu launi da kuma waɗanda ba su da launi iri huɗu.
Ana iya amfani da diodes masu fitar da haske da diodes masu fitar da haske a matsayin fitilun nuna alama.

2. Dangane da halayen mai haskesamanna bututun fitar da haske

Dangane da halayen saman fitar da haske na bututun fitar da haske, ana iya raba shi zuwa fitila mai zagaye, fitilar murabba'i, fitilar murabba'i, bututun fitar da haske na fuska, bututun gefe da ƙaramin bututu don shigar da saman, da sauransu.
An raba fitilar zagaye zuwa Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm da Φ20mm, da sauransu.
Kasashen waje yawanci suna rikodin diode mai fitar da haske Φ3mm kamar T-1, φ5mm a matsayin T-1 (3/4), da kumaφ4.4mm a matsayin T-1 (1/4).

3. Dangane da bayanintsarina'urorin auna haske na diodes

Dangane da tsarin LED, akwai dukkan murfin epoxy, murfin epoxy na tushen ƙarfe, murfin epoxy na tushen yumbu da kuma murfin gilashi.

4. A cewarƙarfin haske da kuma ƙarfin aiki

Dangane da ƙarfin haske da kuma ƙarfin aiki, an raba hasken LED zuwa hasken yau da kullun (ƙarfin haske 100mCD);
Ana kiran ƙarfin haske tsakanin 10 zuwa 100mCD da diode mai fitar da haske mai haske.
Wutar lantarki ta aiki ta janar LED tana daga goma mA zuwa da dama mA, yayin da wutar lantarki ta aiki ta ƙarancin wutar LED tana ƙasa da 2mA (haske iri ɗaya ne da na bututun da ke fitar da haske na yau da kullun).
Baya ga hanyoyin rarrabuwa da ke sama, akwai kuma hanyoyin rarrabuwa ta hanyar kayan guntu da kuma ta hanyar aiki.

Ted: Labari na gaba kuma game da LED ne. Menene? ​​Da fatan za a ci gaba da kasancewa tare da mu.
