A zamanin yau LED ya zama wani ɓangare na rayuwarmu da ba za a iya shiga ba. A yau, zan ba ku taƙaitaccen gabatarwa ga ra'ayi, halaye, da rarrabuwa.

Ma'anar LED

LED (Light Emitting Diode) na'ura ce mai ƙarfi mai ƙarfi wanda ke canza wutar lantarki kai tsaye zuwa Haske. Zuciyar LED ɗin guntu ce ta semiconductor, tare da ƙarshen maƙala ɗaya zuwa ɓangarorin, ƙarshensa wanda ba daidai ba ne, ɗayan ƙarshen kuma yana da alaƙa da ingantaccen ƙarshen samar da wutar lantarki, ta yadda dukkan guntu ke rufe a cikin epoxy guduro.

Wani guntu na semiconductor ya ƙunshi sassa biyu, ɗaya daga cikinsu shine semiconductor nau'in p, wanda ramukan ke mamaye, ɗayan kuma nau'in semiconductor ne, wanda electrons suka mamaye. Amma lokacin da aka haɗa semiconductor biyu, "pn junction" yana samuwa a tsakanin su. Lokacin da aka shafa wutar lantarki a kan guntu ta hanyar waya, ana tura electrons zuwa yankin p-region, inda za su sake haduwa da ramin su fitar da makamashi ta hanyar photons, wato yadda LEDs ke haskakawa. Kuma tsawon hasken haske, launi na haske, an ƙaddara shi ta hanyar kayan da ke samar da haɗin PN.

Halayen LED

Halayen halayen LED sun ƙayyade cewa shine mafi kyawun hasken haske don maye gurbin tushen hasken gargajiya, yana da aikace-aikace masu yawa.

• Karamin Juzu'i

LED shine ainihin ƙaramin guntu wanda aka lulluɓe a cikin resin epoxy, don haka ƙarami ne kuma haske sosai.

-Rashin Amfani da Wuta

Amfani da wutar lantarki yana da ƙasa sosai, gabaɗaya magana, ƙarfin aiki na LED shine 2-3.6V.
Yanayin aiki na yanzu shine 0.02-0.03A.
Wato wutar lantarki ba ta wuce 0.1W ba.

• Tsawon Rayuwa

Tare da daidaitaccen halin yanzu da ƙarfin lantarki, LEDs na iya samun rayuwar sabis har zuwa awanni 100,000.

• Haskaka Mai Girma da Ƙananan Zafi

• Kare Muhalli

LEDs an yi su ne da kayan da ba su da guba, ba kamar fitilun fitulu ba, waɗanda ke ɗauke da mercury kuma suna haifar da gurɓata yanayi. Hakanan ana iya sake sarrafa su.

• Karfi da Dorewa

LEDs suna da cikakken encapsulated a epoxy guduro, wanda yake da karfi fiye da duka fitilu fitilu da kuma kyalli tubes.There kuma babu sako-sako da sassa a cikin fitilar, wanda ya sa LEDs indestructible.

Rarraba LED

1, A cewar bututu mai fitar da haskelaunimaki

Dangane da launin haske na bututu mai fitar da haske, ana iya raba shi zuwa ja, orange, kore (da koren rawaya, koren daidaitaccen koren kore), shuɗi da sauransu.
Bugu da ƙari, wasu LEDs sun ƙunshi kwakwalwan kwamfuta na launuka biyu ko uku.
Dangane da diode mai haske wanda aka haɗe ko ba a haɗa shi da masu watsawa ba, masu launi ko mara launi, launuka daban-daban na LED kuma za a iya raba su zuwa launuka masu haske, mara launi, watsawa masu launi da kuma rarraba mara launi iri huɗu.
Ana iya amfani da diodes masu fitar da haske da haske - masu fitar da diodes azaman fitilun nuni.

2.According to the characters of luminousfarfajiyana bututu mai fitar da haske

Bisa ga halaye na haske emitting surface na haske emitting tube, shi za a iya raba zagaye fitila, square fitila, rectangular fitila, fuskar haske emitting tube, gefen tube da kuma micro tube domin surface shigarwa, da dai sauransu.
An raba fitilar madauwari zuwa Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm da Φ20mm, da dai sauransu.
Kasashen waje yawanci suna rikodin diode mai fitar da haske na Φ3mm azaman T-1, φ5mm kamar T-1 (3/4), daφ4.4mm kamar yadda T-1 (1/4).

3. A cewartsarina diodes masu fitar da haske

Dangane da tsarin LED, akwai duk encapsulation epoxy, ƙarfe tushe epoxy encapsulation, yumbu tushe epoxy encapsulation da gilashin encapsulation.

4.A cewarhaske mai ƙarfi da aiki na yanzu

Dangane da ƙarfin haske da aiki na yanzu an raba shi zuwa LED mai haske na yau da kullun (ƙarfin haske 100mCD);
Ƙarfin haske tsakanin 10 zuwa 100mCD ana kiransa diode mai fitar da haske mai haske.
Aiki na yau da kullun na LED yana daga mA goma zuwa ɗimbin MA, yayin da ƙarancin LED na yanzu yana ƙasa da 2mA (hasken daidai yake da na bututu mai fitar da haske).
Baya ga hanyoyin rarrabuwa na sama, akwai kuma hanyoyin rarraba ta kayan guntu da kuma ta aiki.

Ted: labarin na gaba kuma game da LED. Menene? Da fatan za a kasance da mu.
