GTB 108th Session – Tokyo 26-30 October 2009 PDF Print E-mail
Monday, 02 November 2009
Despite concerns that travel budget restrictions would hinder the latest GTB meetings hosted by JSAE in Tokyo Japan, more than 40 experts from the GTB global membership participated in the many working group meetings that occupied the complete week.

The meetings opened with a review of the outcome of the recent October 2009 GRE session where GTB had submitted 16 proposals for consideration. Of these 14 were adopted and will be transmitted to WP29 for its March 2010 session. The two remaining proposals will be considered again at the next GRE session following incorporation of contributions from GRE experts.

The General Assembly continued to work upon the reorganisation of the GTB operating structure and the working procedures of the working groups and taskforces. This is being done to improve efficiency and value for the members and to ensure that GTB is in a position to continue to provide a comprehensive expert contribution to the work of GRE and WP29.
The GRE chairman, Marcin Gorzkowski, acknowledged the importance of the contribution of GTB during his report to the 148th WP29 session with his reference to the “advantageous cooperation between GRE and GTB,”

Among the work items discussed in Tokyo were:
- Proposals for new light sources including the standardisation of low wattage Gas Discharge Lamps
- Standardised replaceable LED light sources for signalling applications,

ISAL report is released to-day PDF Print E-mail
Sunday, 18 October 2009
Two weeks after the ISAL 2009 Symposium in Darmstatt, this report is meant for experts who were not present or attended the ISAL 2009 Symposium but missed some important lectures.
DVN has made the choice to select around one half of the proceedings with for each, a DVN comment on their content.
Selection was done in function of 3 criteria: Innovation, Time to market, Novelty of the information.

These lectures cover environmental and Physiological aspects, Xenon technologies and its constant progress, the benefits of Xenon 25W to improve safety and wattage consumption versus Halogen, LED technologies and its continuing improvements, as well as adaptive cut-off line and adaptive driving beam, plus combinations of several of these technologies.

DVN was especially interested by following lectures:
- Michael Hamm, AL presenting the concept of the “wattage index” and the effects of various light source technologies, styling and safety on CO2 emission.
- Christoph Schiller, TU Darmstatt, demonstrating that Xenon or LED do not increase discomfort glare
- Masao Okawa, Koito, presenting the LED perceived brightness 60% higher than halogen
- Osram and Philips presenting the Xenon 25W opportunities and acceptance features
- Several speakers presenting the progress of adaptive cut-off or adaptive Driving Beam
- LED matrix light or marking light from the 3 premium car makers
- Michael Kleinkes, Hella, presenting an interesting concept of performance/economy with VisioLED and EcoLED

ISAL 2009 was an exceptional Symposium with plenty of new lighting technologies becoming mature. ISAL 2009 report from DVN helps you to be aware of the technologies developed by your customers, your competitors or your suppliers.
