Lighting engineering and photometrics

The quality of signs directly influences road safety, particularly when their visibility is compromised by meteorological and atmospheric conditions. Additionally, at airports, specific regulations dictate the performance limits for both horizontal and vertical signs, along with the statistical studies needed to establish consistent indices. GRS has been conducting surveys of this nature for decades, consistently meeting the requirements of even our most discerning customers.

Measurement of levels of illumination for indoor and outdoor environments

The level of lighting in a space serves as a crucial indicator of the quality and liveability of an environment. In the case of public buildings, adherence to specific lighting limits, both absolute and relative to adjacent areas, is essential to facilitate their use. In the aeronautical sector, specific regulations outline the minimum values to be met in various airport zones. Over the years, we have developed specific procedures enabling the generation of high-precision isolux curves, effectively identifying any deviations from compliance.

Measurement of the luminance of horizontal signs

In the road sector, and particularly in the airport domain, horizontal signs must adhere to specific performance requirements outlined by international regulations. These requirements consider factors such as the condition of the signs (wet or dry), the detected colour and whether they are illuminated by diffused or reflected light. Sign surveys represent one of our longest-standing services, delivering reports to our customers that align seamlessly with legislative requirements, both on a regular and ad-hoc basis.

Spectrophotometer surveys of horizontal signs

The precise evaluation of the colour of airport sign panels must adhere to specific parameters, and specialized spectrophotometric instruments are employed to obtain the necessary information. Our extensive experience ensures that customers receive prompt, clear, and objective information.
