New player on the market
GL Optic is entering the automotive lighting quality control market with its new photometric systems that offer faster automotive lamps approval Now, the new car revolution, forced by electro mobility and autonomous systems, changes the design styles of vehicles. Engineering teams are in need for speedier photometric systems in order to improve the approval process. For this purpose, new photometric instruments for faster lamps approval are being introduced to the market.
Lamp design is getting more complicated
Multiple functions of modern vehicle headlights make the testing process more sophisticated. Repositioning of the lamp under test to measure low beam, high beam, position light, daylight running light and direction indicator is time consuming. Adaptive headlights with more functions being defined are the latest trend. Also the tail lights are composed in a similar manner in order to integrate various functions. Additionally, new lamps are getting longer and more complicated. Their elegant form puts specific requirements on the testing equipment. As a part of this process, vehicle manufacturers require the right tools for testing during the R&D phase and approval while manufacturing. Everyone wishes to do it precisely and quickly with respect to the existing standards. Due to both the new shapes and sizes of car lamps and in-vehicle lighting there is a growing need for more sophisticated and larger measuring systems.
Meet the game changer for faster vehicle lights approval
For reliable and faster automotive lamps approval, GL Optic presented a preconfigured, turn-key photometric system – GLG A 50-1800. It is built to help solve testing challenges on a daily basis and get prepared for future developments as well. The main features of the type A goniophotometer are 3 mechanized H,V and Z axes and a DUT moving x,y mechanical mounting table. The Goniophotometer GLG A 50 -1800, with increased load capacity, allows the measurement of lamps weighing up to 50kg, with a width up to a 1,8m and extended angular positioning. The large 50cm x 50cm mounting table is adjustable and has 80 cm adjustment in the vertical plane. The measurement of the light signal is provided by GL Photometer 3.0 LS. Its high sensitivity and dynamic range allows the measurement of illuminance from 1/10th of millilux up to 1000 kilolux. Sampling rate of 125kHz allows quicker measurements of illuminance and light modulation (flicker). It has been developed in cooperation with the industry leading suppliers such as Panasonic and Hamamatsu Photonics to ensure the highest accuracy and reliability. A new level of performance and usability is supported by completely new and easy to use software including precise alignment protocols and extensive automation capabilities for the entire system. The GLG A 50-1800 goniophotometer systems are compliant with the conformance testing of lamps and signals to UN/ECE and SAE /FMVSS Regulations and the CIE 121-1996 and IESNA LM-75-01 standards regulating far-field photometric and colorimetric measurement systems.
What about in-vehicle lighting?
Touch screen displays indicating LEDs and LED line illumination must be verified in order to fulfil the quality standards while maintaining consistent. The optical performance of displays and backlit elements requires a dependable luminance testing solution. The GL OPTICAM 2.0 4K TEC is a new high resolution Imaging Luminance Measuring Device. This is a laboratory performance optical camera system featuring a high resolution 9M pixel CMOS image sensor with a dedicated V-Lambda correction filter. Selection of high class lenses is available for the system depending on specific luminance measurement requirements. The system features a unique RFID lens recognition system and a thermal stabilization of the image sensor, which compensates measurement errors resulting from changing temperature conditions. With this new optical instrument all the touch screen control panels, backlit buttons, displays, keyboards and indicating lights can be easily and precisely verified during the R&D and production stage.
One provider – many different solutions
Fast changing design and increasing number of new technical solutions for in-vehicle and exterior lighting creates a challenge in quality verification for system engineers, development teams and QA/QC staff. Starting from single LED emitter or OLEDs, through modules and component testing up to the final lighting assemblies, GL Optic offers comprehensive optical instrument systems for tests and measurements of any kind of lighting in the transportation industry.
