Marka la iibsanayo nalalka, inta badan maqlo shaqaalaha iibka oo leh waxaan nahay nalalka LED-ka, ilaalinta deegaanka iyo badbaadinta tamarta, hadda meel kasta waxaa sidoo kale laga maqli karaa erayada hogaanka ah, marka lagu daro nalalka aan ognahay ee ilaalinta deegaanka iyo badbaadinta tamarta, waxaan badanaa maqalnaa dadka oo sheegaya nalalka cob lamps. , Waxaan aaminsanahay in dad badani aysan si qoto dheer u fahmin cob, haddaba waa maxay cob?Waa maxay farqiga u dhexeeya ledhka?
Marka hore ka hadal LED-ka, nalka LED-ka waa diode ifaya sida isha iftiinka, qaab-dhismeedkiisa aasaasiga ah waa chip semiconductor electroluminescent, waa aaladda semiconductor-ka adag, waxay si toos ah ugu beddeli kartaa koronta iftiinka.Mid ka mid ah cidhifyada jajabku wuxuu ku xiran yahay gunta, hal cidhif ah waa electrode taban, kan kalena wuxuu ku xiran yahay korantada togan ee korontada, si chip oo dhan uu u daboolo resin epoxy, kaas oo ilaaliya fiilada gudaha gudaha , ka dibna qolofka ayaa la rakibay, markaa waxqabadka seismic ee nalka LED waa mid wanaagsan.xagasha iftiinka Led waa weyn yahay, wuxuu gaari karaa 120-160 digrii, marka la barbar dhigo xirmada hore ee plug-in waxtarka sare leh, saxnaanta wanaagsan, heerka alxanka hooseeya, miisaanka fudud, mugga yar iyo wixii la mid ah.
Waagii hore, waxaan aragnay timo-jareyaal, KTV, maqaayado, tiyaataro iyo nalal kale oo ledh ah oo ka kooban nambaro ama kelmado ayaa inta badan loo isticmaali jiray boorarka, nalalka LED-yada ayaa inta badan loo adeegsan jiray tilmaameyaal iyo looxyada LED-yada.Marka ay soo baxaan ledhyo cad, sidoo kale waxaa loo isticmaalaa nalal ahaan.
LED waxaa loo yaqaanaa jiilka afraad ee iftiinka ama isha iftiinka cagaaran, oo leh tamar-badbaadin, ilaalinta deegaanka, nolosha dheer, cabbirka yar, sifooyin ammaan ah oo la isku halleyn karo, oo si ballaaran loo isticmaalo tilmaamayaasha kala duwan, bandhigga, qurxinta, iftiinka dambe, iftiinka guud iyo goobaha habeenkii magaalada iyo beeraha kale.Marka loo eego isticmaalka hawlaha kala duwan, waxaa loo qaybin karaa bandhiga macluumaadka, nalalka taraafigga, nalalka baabuurta, iftiinka dambe ee LCD, iftiinka guud ee shan qaybood.
Aragti ahaan, nolosha adeegga nalalka LED-ka (hal-iftiin bixiye) guud ahaan waa 10,000 saacadood.Si kastaba ha noqotee, ka dib marka la isku daro laambad, sababtoo ah qaybaha kale ee elektiroonigga ah ayaa sidoo kale leh nolol, sidaas darteed nalka LED ma gaari karo saacadaha 10,000 ee nolosha adeegga, guud ahaan, wuxuu gaari karaa oo keliya 5,000 saacadood.
Isha iftiinka COB waxay ka dhigan tahay in chip si toos ah loogu baakadeeyey dhammaan substrate-ka, taas oo ah, N chips waa la dhaxlay oo la isku daray substrate-ka loogu talagalay baakadaha.Tiknoolajiyadani waxay meesha ka saaraysaa fikradda taageerada, dhejis la'aan, dib-u-soo-noqosho la'aan, habsocod balastar ah ma jiro, markaa habka ayaa la dhimay ku dhawaad 1/3, kharashka sidoo kale waxaa lagu badbaadiyay 1/3.Inta badan waxaa loo isticmaalaa in lagu xalliyo dhibaatada soo saarista chip-ka yar ee nalalka LED-ka ee awoodda sare leh, kaas oo kala firdhi kara kuleylka kulaylka, hagaajinta waxtarka iftiinka, iyo hagaajinta iftiinka iftiinka nalalka LED.COB waxay leedahay cufnaanta iftiinka iftiinka sare leh, dhalaal yar iyo iftiin jilicsan, waxayna sii daysaa qaybinta iftiinka lebbiska ah.Marka la eego ereyada caanka ah, way ka horumarsan tahay nalalka LED-ka, nalalka ilaalinta indhaha oo badan.
Farqiga u dhexeeya nalka Cob-ka iyo nalka ledhka ayaa ah in nalka ledhku uu badbaadin karo ilaalinta deegaanka, ma laha stroboscopic, shucaaca ultraviolet ma jiro, khasaaruhuna waa waxyeelada iftiinka buluuga ah.Cob laambad samaynta midabka sare, midabka iftiinka u dhow midabka dabiiciga ah, ma stroboscopic, aan dhaldhalaalka, ma shucaaca electromagnetic, shucaaca ultraviolet ma, shucaaca infrared ilaalin karaa indhaha iyo maqaarka.Labadani dhab ahaantii waa LED, laakiin habka baakadku wuu ka duwan yahay, habka baakadaha cob iyo hufnaanta iftiinka ayaa faa'iido badan leh, waa isbeddelka horumarinta mustaqbalka.
