  7. IEC Definition of Life 3 7

  8. 70 Useful Life and expressed in general as LxBy 100% e.g, Useful Life (L70B50) = 50,000h 70 65 70 90% 75 B50 L70 65 70 75 80% 60 65 70 75 80 70% Relative luminous flux 55 65 60 70 85 75 80 60% 70 55 60 65 50 75 85 80 90 50% 10k 20k 30k 40k 50k 60k 4

  9. 70 Rated Median Useful Life is for the specific case when we have B50 we call this Median Useful Life Lx 100% 70 e.g, Median Useful Life (L70) = 50,000h 65 70 90% 75 B50 L70 65 70 75 80% 60 65 70 75 80 70% Relative luminous flux 55 65 60 70 85 75 80 60% 70 55 60 65 50 75 85 80 90 50% 10k 20k 30k 40k 50k 60k 5

  10. The abrupt light output degradation of a population of LED modules at a certain point in time is called Time to Abrupt Failure and expressed as Cy 70 70 70 e.g, Time to Abrupt Failure (C10) = 53,000h 70 70 70 65 65 65 70 70 70 75 75 75 100% 65 65 65 70 70 70 75 75 75 90% % Survors 60 60 60 65 65 65 70 70 70 75 75 75 80 80 80 80% 0 0 0 65 65 65 60 60 60 70 70 70 85 85 85 75 75 75 80 80 80 70 70 70 0 0 0 60 60 60 65 65 65 10k 20k 30k 40k 50k 60k 0 0 0 75 75 75 85 85 85 80 80 80 90 90 90 53k Time to Abrupt Failure 6

  11. The Rated Abrupt Failure Value (AVF) is the percentage of LED products failing to operate at the Median Useful Life Lx 70 e.g, Rated Abrupt Failure Value(AVF) @ 50kh = 8% 70 65 70 75 100% 65 70 75 92% 90% 60 65 70 75 80 80% 0 65 60 70 85 75 80 70 0 60 65 10k 20k 30k 40k 50k 60k 0 75 85 80 90 Time to Abrupt Failure 7
