Recognizing the limitations of existing test equipment the Canadian Standards Association developed a computer-aided lamp temperature measuring apparatus. This equipment incorporates a simple approach to detecting thermal characteristics of tungsten filament lamps. The key element of this equipment is a data acquisition system that compiles measured test data and selects the maximum temperatures. The test data can be used to develop an empirical equation for determining the maximum temperatures of new tungsten filament lamps. This equation will compute maximum permissible profile temperature limits for new lamps with different bulb size or different lamp wattages.
