SPEEDIER PRODUCT TESTING

Automotive and other vehicle lighting product compliance testing becomes a challange for many engineers in the industry. It’s mainly because the cost optimization and increasing speed of new products introduction onto the market puts additional pressure to measure more, faster and better.

The GLG A 20-300 goniophotometer has been designed for every day application in R&D laboratories and product compliance testing center labs where dependable data is provided by truly user friendly photometric instruments system.

Following the industry standards this goniophotometer system is ready to photometric testing of vehicle LED and other types of lamps luminous intensity distribution in H,V coordinates. Robust design, user friendly interface and top level accuracy available for fast developing industry.

Standards compliance

The GLG A 20-300 goniophotometer systems are type A systems compliant with the CIE 121-1996 and IESNA LM-75-01 standards regulating far-field photometric and colorimetric measurement systems.

Reliable and accurate

The system uses tried-and-tested mechatronic components to provide fast, accurate and reliable measurements of automotive, rail and other vehicle headlamps. Additionally, it can be used for photo-metric characterization of traffic signal lamps and airfield lighting systems. This goniophotometer system is designed for lamps of up to 20 kg and the x,y translation stage surface size is 300 x 300 mm.

Controllable and programmable

Depending on the application the system can be paired with the following measuring instruments:
GL PHOTOMETER 3.0 LS + Flicker
GL SPECTIS 1.0 LS
GL SPECTIS 5.0
A selection of peripheral devices for tests of vehicle headlamps is available.

GLG A 20-300 Usage

Larger capacity

Production and development teams constantly improving lamps and fixtures make more efforts to provide specifications of their products and verify compliance. This creates increasing demand for faster and more flexible light measuring systems. As changes in the industry are speeding up and products are getting more sophisticated, the need for testing and verification becomes more critical.

This type A GL Goniophotometer can be used in factory laboratories as well as in accredited laboratories and deliver fast and reliable results for the measurements of small and lager lamps. Mechanical design includes increased load capacity up to 20kg, large 300x300mm mechanical stage and 3 motorized axis featuring absolute encoders for improved accuracy.

With easy to use software, precise alignment protocols and extensive automation capabilities, the system offers a new level of performance and usability.

Speedier lamp testing

Default measuring instrument included in the system is the GL PHOTOMETER 3.0 LS + Flicker which has been designed for On Fly ( non stop ) measurements of automotive and other lamps on goniophotometer.

High sampling rate combined with high sensitivity HAMAMATSU sensor allows for continuous measurement of LED during smooth movement of DUT ( Device Under Test ) Thanks to absolute encoder readings the required data can be obtained in much shorter time.

With this super fast measuring instrument, additional light modulation characterization for turn lights and emergency signals is available using the flicker measurement functionality.

Need to measure color?

The GL goniospectrophotometer design offers a turn-key LED light measurement system which can be equipped with one of our optional spectroradiometers to add full color measurement capability.

The GL SPECTIS 5.0 can be used for advanced systems covering extended spectral analysis also outside the visible range from UV to NIR sources angular distribution in a variety of applications.

Our basic instrument GL SPECTIS 1.0 LS is a high sensitivity version of our popular spectroradiometer optimized for fast photometric & colorimetric measurements.
