Example of Failure Rate Calculation
Assume a device operating 8 hours/day, 5 days/week. The utilization factor, given 168 hours/week is:
(8 hours/day) x (5 days/week) / (168 hours/week) = 0.25
The point failure rate per year (8760 hours) at 55
°
C ambient temperature is:
(0.893% / 1K hours) x (0.25) x (8760 hours/year) = 1.96% per year
Similarly, 90% confidence level failure rate per year at 55
°
C:
(2.056% / 1K hours) x (0.25) x (8760 hours/year) = 4.50% per year

Notes:
[1] The point typical MTBF (which
represents 60% confidence level) is the
total device hours divided by the
number of failures. In the case of zero
failures, one failure is assumed for this
calculation.
[2] The 90% Confidence MTBF represents
the minimum level of reliability
performance which is expected from
90% of all samples. This confidence
interval is based on the statistics of the
distribution of failures. The assumed
distribution of failures is exponential.
This particular distribution is commonly
used in describing useful life failures.
Refer to MIL-STD-690B for details on
this methodology.
[3] A failure is any LED which is open,
shorted, or fails to emit light.
[4] Calculated from data generated at
55
°
C biased at 50 mA.
