For example, let's calculate the operating life of the GaAs LED, based on the data shown on page 60.
Here is an example of how to read an operating life, assuming that the ambient temperature (Ta) is 40°C and that the failure
criterion is a 30% decrease in light output.
Suppose that the initial LED current, IF, is 20 mA. Since the horizontal axis of the failure criteria graph is the reciprocal of absolute
temperature, it is necessary to convert the ambient temperature (Ta) to the reciprocal of absolute temperature (T):
The graph shows the projected lifetimes for F50% and F0.1% cumulative failure probabilities in solid and dashed lines respectively.
Normally, it is recommended to use F0.1% lines.
As X = 3.19, its intersection with the IF = 20 mA line for F0.1% is approximately 80,000 hours. (This figure is for reference only.)
You can also estimate the projected operating life from the projected light output degradation data.
