Współczesne diody LED charakteryzują się imponującymi parametrami eksploatacyjnymi, zarówno w odniesieniu do generowanych strumieni świetlnych, jak i sprawności przetwarzania energii elektrycznej. Jednak w wielu przypadkach, parametry podawane w notach aplikacyjnych, nie są możliwe do osiągnięcia. Fakt ten wynika z prezentacji tych danych w warunkach cieplnych nie występujących podczas normalnej eksploatacji...
Today’s LED’s are characterized by high exploitation parameters. Both light intensities and efficiencies are highest in comparison to other light sources. But, in many cases, parameters given in application notes are impossible to reach. In the article some aspects of thermal energy dissipation from p-n junctions were discussed. Some methods for measurements of thermal resistance of LED junctions...
