Infrardeča termografska analiza LED svetil na keramični plasti : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoPurič, JakaLED svetila intenzivno nadomeščajo žarnice z volframovo žarilno nitko, pri čemer je poleg doseganja dobrih optičnih lastnosti pomembno zagotavljati njihovo učinkovito hlajenje. V tej nalogi ... obravnavamo infrardečo termografsko analizo dveh različnih LED svetil na keramični plasti z debelinami od 0,25 mm do 5 mm. Razvita je bila eksperimentalna proga, ki omogoča napajanje LED svetila z omejevanjem električnega toka in napetosti ter sočasno spremljanje porabe električne moči in merjenja temperature s pomočjo hitrotekoče infrardeče kamere. V okviru meritev smo analizirali segrevanje keramičnih plasti različnih debelin, vpliv orientacije LED svetila, dinamični odziv segrevanja in čas, potreben za doseganje ustaljenega temperaturnega stanja pri različnih električnih močeh. Prikazani so tudi temperaturni profili in dvodimenzionalna temperaturna polja. Rezultati meritev kažejo, da razviti merilni postopek omogoča vrednotenje segrevanja LED svetil in določanja maksimalne dovoljene električne moči, da zadostimo temperaturnim omejitvam.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
