Sidee U Shaqeeyaan Laydhka Waddooyinka LED?

Iftiinka waddooyinku wuxuu soo maray waddo dheer ilaa maalmihii hore ee nalalka gaaska iyo nalalka shidan. Maanta, nalalka LED-yada ayaa ah heerka ugu sarreeya - iyo sabab wanaagsan. Waxay yihiin kuwo tamar-ku-ool ah, waara oo kharash-ool leh. Dhab ahaantii, magaalooyin badan oo adduunka ah ayaa u wareegay iftiinka waddooyinka LED si ay u badbaadiyaan isticmaalka tamarta oo ay u yareeyaan qiiqa kaarboonka.

Laakiin sidee ayay dhab ahaan u shaqeeyaan nalalka waddooyinka ee LED? Aan u daadagno cilmiga iyo tignoolajiyada ka dambeeya cajaa'ibyadan casriga ah ee iftiiminta.

Ciwaanka hoose: Laga soo bilaabo Iftiiminta ilaa LED

Ka hor inta aynaan u gelin sida ay u shaqeeyaan nalalka LED-yada, aan si degdeg ah u eegno taariikhda iftiinka waddooyinka. Laga bilaabo horraantii 1800-aadkii, nalalka gaaska ayaa shidmay waddooyinka magaalada. Ma ahayn ilaa dabayaaqadii 1800aadkii in nalalka wadooyinka ee korantada ay noqdeen kuwa caan ah. Si kastaba ha ahaatee, noocyadii hore ee laydhka dariiqyada ee korantada ayaa isticmaalay nalalka iftiinka, kuwaas oo aan ahayn kuwo tamar badan ama waqti dheer soconaya.

Dabadeed, 1960-kii, waxa la sameeyay diode-kii ugu horreeyay ee iftiimiya. Si kastaba ha ahaatee, ma ahayn ilaa 1990-meeyadii in nalka LED uu bilaabay inuu galo warshadaha iftiinka waddooyinka. Hadda, nalalka waddooyinka ee LED waa halbeegga magaalooyin badan oo adduunka ah.

Ciwaanka hoose: Qaybaha Muhiimka ah ee Laydhka Waddada LED

Kahor intaanan eegin sida ay u shaqeeyaan nalalka LED-yada, waxaan u baahanahay inaan fahanno qaybaha aasaasiga ah ee qalabkan nalalka. Waa kuwan afarta qaybood ee aasaasiga ah:

- chips LED: Kuwani waa ilaha iftiinka yar ee soo saara iftiinka dhabta ah.

- Darawalka LED: Qaybtani waxay nidaamisaa awooda la siiyo chips-ka LED waxayna caawisaa hubinta wax soo saarka joogtada ah.

- Weelka kulaylka: Nalalka waddooyinka ee LED waxay soo saaraan kuleyl, sidaas darteed weel kuleyl ayaa loo baahan yahay si ay u baabi'iso oo ay nalalka uga ilaaliso kulaylka.

- Nidaamka indhaha: Tan waxaa ku jira muraayadaha iyo muraayadaha, kuwaas oo ka caawiya toosinta iftiinka meesha loo baahan yahay.

Ciwaanka-hoosaadka: Sayniska Ka Danbeeya Laydhka Waddada LED

Haddaba, sidee bay u shaqeeyaan nalalka waddooyinka ee LED? Waxaas oo dhan waxay ku xiran tahay sayniska semiconductors. Tiknoolajiyada LED waxay isticmaashaa semiconductors si ay tamarta korontada ugu beddesho iftiinka. Marka korontadu dhex socoto semiconductor, waxay soo daysaa tamar qaab sawiro ah. Midabka iftiinka wuxuu ku xiran yahay nooca semiconductor ee la isticmaalo.

Nalalka LED-yadu aad bay uga tamar badan yihiin nalalka ifaya sababtoo ah waxay u beddelaan ku dhawaad ​​dhammaan tamarta ay isticmaalaan iftiinka. Nalalka laydhka, dhinaca kale, waxay soo saaraan kulayl badan, taas oo ah tamar lumis. Tani waxay ka dhigaysaa nalalka LED-ka inay aad uga kharash badan yihiin kuwii ka horreeyay ee shidmay.

Ciwaanka hoose: Faa'iidooyinka Laydhka Jidadka LED

Nalalka LED-yada waxay bixiyaan faa'iidooyin dhowr ah marka loo eego noocyada kale ee nalalka waddooyinka. Waa kuwan qaar ka mid ah faa'iidooyinka muhiimka ah:

- Tamar fiican: Nalalka waddooyinka ee LED waxay isticmaalaan tamar aad uga yar marka loo eego nalalka iftiinka iyo xitaa nalalka fluorescent.

- Waara: Nalalka LED-yada waxay socon karaan ilaa 100,000 saacadood, taas oo aad uga dheer noocyada kale ee iftiinka.

- Dayactirka hoose: Sababtoo ah nalalka LED-ku waxay sii jiraan wakhti dheer, waxay u baahan yihiin dayactir yar marka loo eego noocyada kale ee nalalka waddooyinka.

- Soosaar hoose: nalalka wadooyinka ee LED waxay sii daayaan CO2 iyo wasakh kale oo aad uga yar marka loo eego noocyada kale ee nalalka wadooyinka.

- Toosin: Nalalka LED-yada waxaa loo hagi karaa si ka saxsan noocyada kale ee nalalka, taas oo macnaheedu yahay inay si hufan u iftiimin karaan meelo gaar ah.

Ciwaanka hoose: Codsiyada Laydhka Waddada LED

Nalalka LED-ka waxaa loo adeegsadaa goobo kala duwan, laga bilaabo magaalooyinka waaweyn ilaa waddooyinka waaweyn ee miyiga. Waa kuwan qaar ka mid ah codsiyada ugu caansan ee nalalka waddooyinka ee LED:

- Waddooyinka magaalada: Magaalooyin badan oo waaweyn oo adduunka ah ayaa isu beddelay laydhka waddooyinka ee LED si loo yareeyo isticmaalka tamarta iyo kharashaadka yar.

Jidadka waaweyn: Nalalka LED-yada waxaa loo adeegsadaa waddooyinka waaweyn iyo nidaamyada gobollada si ay u bixiyaan muuqaal wanaagsan oo loo yareeyo shilalka.

- Goobaha la deggan yahay: Nalalka LED-yada ayaa sidoo kale caan ku ah meelaha la deggan yahay sababtoo ah waxaa lagu tilmaami karaa inay iftiimiyaan meelo gaar ah iyada oo aan lagu daadin guryaha deriska ah.

- Goobaha baarkinka: Goobo badan oo baabuurta la dhigto ayaa lagu shiday nalalka LED-ka sababtoo ah waa kuwo kharash-ool ah oo tamar fiican leh.

Ciwaan-hoosaad: Gabagabadii

Nalalka waddooyinka ee LED-ku waa hal-abuur cusub oo la yaab leh oo dhinaca nalka ah. Waxay yihiin kuwo tamar-ku-ool ah, waara oo kharash-ool ah, iyaga oo ka dhigaya kuwo ku habboon codsiyada kala duwan. Markaad fahamto sida ay u shaqeeyaan nalalka LED-yada iyo faa'iidooyinka muhiimka ah ee ay bixiyaan, waxaad si fiican u qadarin kartaa saameynta ay ku leeyihiin magaalooyinka iyo magaalooyinka adduunka.
