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...
Artykuł przedstawia konstrukcję rejestratora temperatury opartego o mikrokontroler Pic18f4320 firmy Microchip. Przedstawiono sposób wykonania pomiarów temperatury, również wartości ujemnych, wraz z prostym algorytmem usuwania zakłóceń pomiarowych. To niedrogie urządzenie, wyposażono w wiele użytecznych funkcji jak: dwustawną regulację temperatury, pomiar natężenia prądu pobieranego przez elementy...
