Abstract

Un módulo de iluminación de diodos fotoemisores (LED) realiza un diagnóstico integrado; por ejemplo, los diagnósticos pueden incluir calcular la vida útil transcurrida, la degradación de fósforo, la falla térmica, la falta de los LED o el ajuste de corriente LED basado en el flujo o la temperatura medidos; la vida útil transcurrida puede calcularse al proyectar la vida útil transcurrida acumulada de operación mediante un factor de aceleración derivado de las condiciones de operación reales, tal como temperatura, corriente y humedad relativa; la degradación de fósforo puede calcularse con base en una respuesta medida del fósforo para impulsar la luz de los LED; una falla térmica puede diagnosticarse usando una respuesta transitoria del módulo de una condición de arranque; la falla de los LED puede diagnosticarse con base en el voltaje directo medido; la corriente para los LED puede ajustarse usando valores de flujo medido y valores de corriente y una relación deseada de los valores de flujo; adicionalmente, la corriente LED puede proyectarse con base en una temperatura medida.
