Waa maxay Mabaadi'da Kuul Laambada Midabka leh ee LED?

Magaca buuxa ee LED-ku waa semiconductor emitting diode, kaas oo ka samaysan walxo semiconductor. Mabda 'shaqeedkeedu waa in ay si toos ah u beddesho tamarta korantada una beddesho tamarta indhaha, lambarka korantadana waxaa loo beddelaa aalad iftiin ah oo ifaysa. Faa'iidooyinkeedu waa: isticmaalka hooseeya, dhalaal sare, midab qani ah, caabbinta gariir xoog leh, nolol dheer oo adeeg ah (iftiinka caadiga ah wuxuu gaaraa 80,000 ilaa 100,000 saacadood), iftiinka qabow, iwm, ayaa la odhan karaa waa iftiin cagaaran oo dhab ah. Alaabta iftiinka leh ee LED sida isha iftiinka cusub waxay hubaal ahaan bedeli doontaa nalalka dhar-xidhka cad ee mustaqbalka qarniga 21-aad, oo noqda kacdoon kale oo iftiiminaya aadanaha. Kuullaha nalalka LED-ku waxay isticmaalaan sahay koronto yar-yar, korantada korontada waxaa lagu hayaa inta u dhaxaysa 2-4V. Marka loo eego kala duwanaanshiyaha badeecada, laambada LED-ku waa koronto-koronto oo aad u sarreeya marka loo eego adeegsiga awoodda korantada sare, taas oo si gaar ah ugu habboon codsiga goobaha dadweynaha ee goobaha dadweynaha. Halabuurka nalalka LED-ka ee midabka leh waxaa ka mid ah casaan (R), cagaar (g), iyo buluug (b) saddex-saldhig LED. Qof kastaa wuu yaqaannaa LED laba midab leh. Caadi ahaan ka kooban LED iftiin cas iyo LED cagaaran. Waxay si madaxbanaan u dayn kartaa iftiin casaan ama cagaar ah. Haddii iftiinka cas iyo iftiinka cagaaran ay yihiin kuwo iftiiminaya isku mar, labada nuuc ee iftiinka casaanka iyo cagaarka ayaa lagu qasi doonaa orange-jaalle. Mabda'a midabaynta nalka midabaynta ayaa ah marka saddex LED oo aasaasi ah ay iftiimiyaan laba LEDs, waxay soo saari karaan huruud, guduud, cyan (sida casaanka iyo buluugga LEDs marka ay iftiiminayaan iftiin guduudan); Haddii saddexda LED ee iftiinka buluuga ah isku mar, waxay soo saari doonaan iftiin cad. Haddii ay jirto wareeg ah oo iftiimin karta iftiinka casaanka, cagaarka iyo buluuga ah ee LED siday u kala horreeyaan, iftiiminaya, oo shidan saddex midab oo kali ah, markaa toddoba midab oo kala duwan ayaa la soo saari karaa, markaa ifafaalaha nalalka LED-yada midabka leh ayaa soo muuqda.
