Qaybaha nalalka LED-ka: Qalabka semiconductor chip, koollo cad, guddiga wareegga, resin epoxy, silig xudunta ah, qolof.Laydhka LED-ku waa qalabka elektiroonigga ah ee semiconductor-ka, kaas oo lagu daaweeyo gunta oo leh xabag qalin ah ama koollo cad, ka dibna ku xidha chip-ka iyo looxa wareegga oo leh silig qalin ah ama silig dahab ah.Ku hareeraysan waxa lagu xidhay resin epoxy si loo ilaaliyo xadhigga xudunta u ah gudaha.Shaqada, ugu dambeyntii rakib qolofka, sidaas darteed nalka LED wuxuu leeyahay waxqabadka seismic wanaagsan.

Diode-ka-soo-saarka LED-ku waa qalab-ku-meel-gaar ah oo adag oo tamarta korantada u beddeli kara iftiin muuqda.Waxay si toos ah ugu beddeli kartaa koronto iftiin.Wadnaha LED-ku waa chip semiconductor, hal cidhif ah ayaa ku xidhan taageero, hal dhamaadka waa tiirka taban, dhamaadka kalena waxa uu ku xidhan yahay cirifka togan ee sahayda korontada by epoxy resin.

Mabda'a iftiiminta iftiinka ee nalalka LED

Marka hadda uu dhex maro waferka, electrons-yada ku jira semiconductor-ka nooca N iyo godadka ku jira semiconductor-ka nooca P-ga ah ayaa si ba'an isugu dhaca oo dib ugu biira lakabka iftiiminaya si ay u soo saaraan photons, kuwaas oo soo saaraya tamarta qaabka photons (taasi waa , iftiinka uu qof walba arko).Semiconductors qalab kala duwan ayaa soo saari doona midabyo kala duwan oo iftiin ah, sida iftiinka cas, iftiinka cagaaran, iftiinka buluuga ah iyo wixii la mid ah.

Inta u dhaxaysa labada lakab ee semiconductors, electrons iyo godad ayaa isku dhaca oo dib isu keena oo soo saara sawiro buluug ah lakabka iftiiminaya.Qayb ka mid ah nalka buluuga ah ee la dhaliyo ayaa si toos ah uga bixi doona iyada oo loo marayo daaha fluorescent;qaybta soo hartay waxay ku dhufan doontaa daaha fluorescent waxayna la falgali doontaa si ay u soo saarto sawiro jaale ah.Sawirka buluugga ah iyo sawirka jaalaha ah ayaa wada shaqeeya (isku dhafan) si ay u soo saaraan iftiin cad
