Lighting Laboratory

Our lighting laboratory is equipped with high-tech instruments such as the Spectroradiometer and the Goniophotometer, which allow us to obtain essential data about luminaires and lighting devices. We also have equipment for Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) testing.

Spectroradiometer

Performs analyses of the visible optical spectrum distribution, providing essential information about the equipment.

Key data highlighted:

  • Chromatic: chromaticity coordinates x and y, correlated colour temperature (CCT), peak wavelength, colour rendering index (CRI)

  • Photometric: luminous flux, luminous efficacy;

  • Electrical: current, power, power factor;

  • LED optical maintenance test: flux vs time, power vs time.

Our spectroradiometer has two integrating spheres, one for equipment up to 30 cm and another for equipment up to 2.00 m.

Goniophotometer

The goniophotometer is a high-precision instrument used to measure the variation of luminous intensity of a device, as well as to generate photometric data files.

Combining the goniophotometer data with the spectroradiometer allows us to obtain spectral data.

All Nexled luminaires and lighting devices undergo extensive testing to obtain complete spectral data.

EMI and EMC

EMI refers to vulnerability to electromagnetic interference, which can disrupt equipment performance. This interference may have environmental causes, such as solar radiation, though the most common sources are electrical systems and other electronic devices.

EMC relates to a device's ability to operate without being affected by other electronic equipment in the same environment, and without interfering with the proper operation of these devices.

These results come from various tests conducted on the equipment. At Nexled, we have instruments such as the EFT immunity tester, the surge generator, and the EMI test receiver.
