GL Optic Offers Fast and Reliable Measurements for Automotive Lighting

Nowadays car manufacturers are facing rapid strides in the development of automotive lighting meaning that the sole functionality of the lamps are no longer the major focus. Special attention is payed to new shapes, sizes and designs and the overall user-experience. These are key factors that need to be considered in order to be able to compete in increasingly faster growing markets. GL Optic introduces a new type A Goniophotometer, the GLG A 50-1800, to accommodate these requirements perfectly.

The main product focus for measurements in the automotive sector is on the new type A Goniophotometer, the GLG A 50-1800, which is used to measure exterior lighting of vehicles. This new Gonio photometer system is suitable for the complete photometric characterization of automotive lamps in H and V axis coordinates and is therefore utilized for the exterior lighting of vehicles, such as headlight indicators or brake lights.

The system complies with the CIE 121-1996 and IESNA LM-75-01 standards that regulate photometric and colorimetric far-field measurement systems. In addition, it is in accordance with UN/ECE and SAE/FMVSS standards.

The GLG A 50-1800 Goniophotometer is constructed for everyday use in research and development laboratories as well as in laboratories of product conformity testing centers, where reliable and accurate data needs to be provided by a user-friendly goniophotometric system.

The goniophotometer is specifically designed for photometric testing of the luminous intensity distribution of automotive LEDs and other lamp types in H, V coordinates. With a fast photometer, it is possible to measure from distances > 3 m, 10 m and 25 m.

Combined with various spectrometers from GL Optic, for instance the GL SPECTIS 5.0 Touch or the GL PHOTOMETER 3.0 LS + Flicker, the scope of functions can be extended depending on the specific application and measurement task.
The goniometer system is suitable for test samples with dimensions of up to 1800mm and a weight of up to 50 kg.

GL Optic is participating in this year's edition of the international lighting fair Light + Building, taking place in Frankfurt a.M. between 8th and 13th of March 2020.
