Menene ka'idar fitar da hasken fitilun LED?

Menene ka'idar fitar da hasken fitilun LED? Fitilar LED wani guntu ne na kayan aikin lantarki na lantarki, wanda ake warkewa akan sashi tare da manne na azurfa ko farar manne, sannan a haɗa shi da guntu da allon kewayawa tare da azurfa ko wayoyi na zinariya, kuma a rufe shi da resin epoxy kewaye da shi don kare ainihin waya ta ciki. Aiki, an shigar da harsashi na ƙarshe, don haka juriya na fitilun LED yana da kyau. 1. Tsarin Fitila Daya daga cikin mahimman abubuwan da ke ba da haske na fitilun LED (Light Emitting Diode) shine fitilar fitila mai girman girman wake a cikin fitilun. Duk da girmansa karami ne, amma aikinsa ba kadan ba ne.

Bayan zuƙowa a kan tsarin fitilun fitilar LED, za mu sami walƙiya mai girman nau'in sesame. Tsarin guntu yana da sarƙaƙƙiya, kuma ya kasu kashi da yawa: Layer Z na sama ana kiransa Layer semiconductor Layer P-type, tsakiyar Layer shine mai haske mai haske, ƙaramin Z Layer kuma ana kiransa N-type semiconductor Layer. To, ta yaya ake fitar da hasken LED? 2. Ka'idar saukarwa daga ra'ayi na zahiri: Lokacin da na yanzu wucewa cikin wafer-treatectorctors, wanda ke haifar da makamashi, wanda ke haifar da wutar lantarki a cikin hanyar phothon (wato, hasken da kuka gani).

Led LED kuma ana kiransa diode haske mai haske, ƙarar sa ƙanƙanta ne kuma mai rauni sosai, bai dace da amfani da shi kai tsaye ba. Don haka mai zanen ya ƙara masa harsashi mai kariya kuma ya rufe shi a ciki, ta haka ya samar da katakon fitila mai sauƙin amfani. Bayan haɗa da yawa LED fitilu beads tare, daban-daban LED fitilu za a iya kafa.

3. Fitilar LED na launuka daban-daban Semiconductors na kayan daban-daban za su samar da launuka daban-daban na haske, kamar haske ja, hasken kore, haske shuɗi da sauransu. Koyaya, babu wani abu na semiconductor da zai iya fitar da farin haske ya zuwa yanzu. Amma ta yaya ake samar da farar fitilar fitilar da muke yawan amfani da ita? 4. Generation na farin LED fitilu Anan muna buƙatar ambaton wanda ya lashe kyautar Nobel - Dr. Shuji Nakamura.

Ya kirkiro ledojin shudi, wanda kuma ya kafa wani harsashi ga farin ledojin. Dangane da wannan gagarumar gudunmawar, an ba shi lambar yabo ta Nobel a fannin Physics a shekarar 2014. Dangane da yadda LEDs blue LED ke rikidewa zuwa farar ledoji, babban dalilin shi ne akwai karin phosphor a cikin guntu.

Ainihin ka'ida mai fitar da haske ba ta canza da yawa ba: Tsakanin nau'ikan semiconductor biyu, electrons da ramuka suna karo kuma suna sake haɗuwa don samar da shuɗin photon a cikin Layer mai fitar da haske. Wani ɓangare na hasken shuɗi da aka samar zai wuce ta cikin rufin mai kyalli kuma za a fitar da shi kai tsaye; ragowar ɓangaren zai bugi murfin mai kyalli kuma yayi hulɗa da shi don samar da photon rawaya. Ana samar da farin haske ta hanyar haɗa (haɗuwa) photon shuɗi tare da photon rawaya.

A halin yanzu, kewayon aikace-aikacen fitilolin LED ya zama ruwan dare gama gari. Ɗaukar Xinshengkai Optoelectronics a matsayin misali, da LED haske tube samar da shi ne yadu amfani a cikin gida da waje ado, titi scene layout, kayan ado counters, lambuna, motoci, wuraren waha, talla ãyõyin, hotels, shopping malls, KTV, leisure wuraren, da dai sauransu Idan aka kwatanta da na gargajiya lighting kayan aikin, LED fitilu ne mafi zamani da kuma gaye, kuma sun kasance a cikin rayuwa despens kayayyakin.
