The use of thermography within the lamp manufacturing industry can improve the quality of many types of lamps ranging from normal incandescent lamps to highly specialized lamps for sports arenas, airports or small lamps for cars. There is a strong demand for more light for the same energy input. Specialized lamps for all possible purposes are developed. But it also forces the lamp manufacturers to utilize the available materials to their extremes. The exact control of the temperatures inside or on the lamp shell has therefore become increasingly necessary as temperatures in lamps can be rather extreme. In plasma lamps for example, the plasma can have a temperature of 6000 C, the bulb around 700 C and the electrodes inside the bulb can have temperatures in excess of 2000 C. Thermographic methods have shown their applicability for a large number of measurement cases. Some of these methods and measurement cases are described. As these applications put very special demands on the measurement equipment, these demands are explained in more detail.
