Abstract
The system for remote and non-visual detection of illumination device operation which is operational to identify the operational state of individual illumination devices. This is accomplished by placing the unit under test in a steady state operating condition during the burn-in and/or environmental stress testing process. The illumination devices are individually selected and operated during the test and the operational state of the selected illumination device determined. The determination of the operational state of the illumination device is effected by measuring the incremental change in power drawn by the unit under test resulting from the activation of the selected illumination device. An anomaly in the measured change in power consumption is indicative of a failure mode for the selected illumination device. Where the unit under test contains a plurality of illumination devices, the illumination devices can be checked seriatim and the type of illumination device can also be determined by the power consumption of the activated illumination device to thereby identify misinstallation of illumination devices.
