Evaluation of test setups and characteristics of test signals for immunity test of light products
Emission, propagation and impact of distortion from appliances containing power electronics is today well known in the harmonic range, up to about 2 kHz. To deal with this, methods have been introduced to minimize disturbances in the harmonic range which among other things has led to that the emission has moved to the frequency range above 2 kHz.
In this frequency range it is found that the emission becomes more complex. If manufacturers and end-users of new energy-saving lighting should not face any unnecessary barriers, it requires methods to assess whether the lighting will be affected by these distortions in real installations. This project aims to find better ways to test lamps based on the immunity test signals that are sufficiently representative to be able to predict how light will behave in real-world conditions. Results and recommendations from the project will be spread among researchers, manufacturers and end-users of energy-efficient lighting, and standardization bodies.
