  • Method for predicting failure of a light-emitting diode
    Patent number: 10001522
    Abstract: A method for predicting failure of a light-emitting diode, includes applying a test potential difference across the terminals of the light-emitting diode lower than its minimum drive potential difference, the test potential difference having the same sign as the minimum drive potential difference; measuring the current Ic flowing through the light-emitting diode during the application of the test potential difference; and generating an alarm signal when the measured current Ic exceeds an alarm threshold Ia.
    Type: Grant
