Mean value shown of 32 devices each. LED’s generally display a degradation in their optical power depending on the profile of the individual application, i.e. the forward current, chip temperature and operating time. Typical behavior is shown in Figure 3, from which the service life can be inferred. Depending on the profile of use the light yield can be reduced by 30% to 50% during deployment in an industrial application (e.g. 50,000 hours), making an LED power control necessary. The design and dimensioning of the LED circuitry is determined by the qualification according to the application-specific profile of use. iC-TL33 illumination pattern -2 -30% 0 Figure 1: Maximum power dissipation with respect to temperature -3 -20% -40% AMBIENT TEMPERATURE [°C] Distance LED to sensor: 10 mm 125°C, 50 mA forward current (mean of 32 devices) -10% dis- State-of-the-art technology guarantees a minimum beam power in an as-received condition with a defined current (25°C). A run-in at an operating point of 20 mA and a chip temperature of 125°C for 72 hours enables statements to be made as to the initial degradation during an accelerated stress test; it does not, however, provide any conclusions as to the service life of the LED.
