Comportamento de controladores de módulos a LED com a variação da temperatura ambiente

Abstract:

Temperature variations affect the operation of electronic devices. In this article we analyze effects that temperature variation entails a LED lamp commonly used in Brazil. Was simulated temperature variations through the use of an oven of 1 m³. Then obtained emission spectrum in the visible, CRI, Correlated Color Temperature, harmonic distortion on the current, supply current, and CIE Chromatic Coordinates x and y in two situations: first with the LED module and controller inside the oven and second with the controller outside. The temperature was monitored in different part of this set. Interesting correlations for specifiers and developers were found.
