Measurement of chromaticity coordinates
Chromaticity coordinate measurement is one of the key measurements taken in the lighting industry. It involves determining the exact values of the chromaticity coordinates for the light emitted by different lighting sources.
The closer the test light is to the white point, the closer its colour is to the ideal white light.
The corresponding values of the chromaticity coordinates thus make it possible to determine whether the light emitted by a given lighting source is close to the ideal or whether it requires correction.
Measurement of chromaticity coordinates is carried out using special devices called spectrophotometers. Such devices make it possible to accurately determine the spectrum of light emitted by a source and calculate the value of the chromaticity coordinates on this basis. This measurement can be performed both for individual light sources and for entire lighting systems.
Performing a chromaticity coordinate measurement is particularly important for lighting that will be used in applications that require accurate colour reproduction, such as photography, filming or medicine. In the lighting industry, this measurement also makes it possible to compare the colour quality of different lighting sources and to identify potential problems related to the colour quality of the light they emit.
A number of norms and standards are used in the field of chromaticity coordinate measurements, such as PN-EN 13032-4:2016-02: ‘Light and lighting – Measurement and presentation of photometric data of lamps and luminaires – Part 4: LED lamps, modules and luminaires’.
In Poland, as in other EU countries, lighting quality regulations have been harmonised with EU requirements and are based on the above standard and other international standards.
What does the implementation of the measurement look like?
1. The first step is to contact us to find out more about our services and to arrange a measurement.
2. The next step is to have the measurements carried out by our experienced professionals, who have the knowledge and skills needed to measure accurately and precisely.
3. Once the measurements have been completed, we analyse the results, which are carefully collated and reported. If required, we can provide the results in electronic or printed form.
4. Finally, we complete the job by providing full technical support to the client. In addition, we can offer advice on the interpretation of the measurement results and their application in practice.
