Heat measurements

With certain technologies, the heat experienced by the light source and the ballast (or driver) affects the overall performance of the luminaire in terms of light output, colour quality, lumen maintenance, lamp life, and ballast (or driver) life.

For this reason, good thermal control is a very important aspect of luminaire design. Our engineers dedicate much energy to the various aspects of thermal control.

Heat measurements are of major importance for finding critical component temperatures, in order to obtain the longest possible lifetime for the product, and to determine the maximum ambient temperature (Ta value) for the luminaire. All measurements are done according to IEC/EN60598. If the Ta value of a luminaire is not stated, the value is 25°C.
