Product approval tests and development-related measurements
Vehicle headlights, retroreflectors, signal lamps, variable message signs and airfield lighting systems guarantee the safety of traffic participants. They are therefore subject to strict legal requirements in terms of their photometric properties.
The challenge: Compliance with standards
Many standards prescribe strict limits for e.g. luminous intensity distribution, light color, retroreflection, luminance, red component or UV-proportion. In order to provide evidence of compliance with UN-ECE, SAE, FVMSS108, GB, FAA or ICAO, the products must undergo tests throughout the development process, during production (CoP) and product certification.
Statutory approval tests for automotive exterior lighting are strictly regulated, e.g. by:
- GTB Photometry Accuracy Guidelines
- SAE Standard J1330
- DIN 5032-7 (2017)
- EN-DIN 13032-1
These provide precise standards for the selection of suitable measurement technology.
LEDs, OLEDs, PWM, high-definition headlamps
In vehicle lighting technology there has been a constant stream of developments in terms of new photometric solutions. Narrow-band, frequently pulse-width modulated LED light sources are being used in glare-free headlights with millions of pixels and a large number of different light distributions.
Accuracy of the measuring system is critical
The new light sources call for a particularly high degree of precision in sample positioning by a Type A goniometer and higher spatial resolution of the photometer used. The appropriate software must be incorporated in the measurement system to control all functions of these samples. Precision, measurement speed and efficiency are thus a decisive factor in the choice of system.
