2009 may in time come to be seen as a turning point in the automotive industry, with the sinking of GM after 100 years of industrial leadership, and the possible overtaking of Toyota by VW as the number-1 automaker worldwide. Toyota have undoubtedly been the champion of global car mass manufacturing, while VW are taking the lead thanks to attractive car models the success of which is driven by innovative and stylish features, appealing to buyers on an emotional level.

Lighting Safety
Tuesday, 22 September 2009

This report, in 80 pages, provides comprehensive coverage of lighting and signalling technology and technique in production and under development, as well as discussion of drivers’ and pedestrians’ reciprocal awareness and a status of worldwide studies from universities, institutes and industrial companies on the safety effects of lighting. Tungsten-halogen, Xenon, and LED light sources are covered, as are reflector optics, all variants of the projector concept, and modular LED optics. Advanced lighting control systems are presented by category and by maker. All of these technologies and systems are evaluated with respect to their safety performance contribution. For each technology presented, the position of the main suppliers is defined.

Signal lamps as a brand signature
Tuesday, 28 July 2009

Lights started out as basically functional devices added to vehicles with little thought to design.
Their integration into overall vehicle design has gradually and progressively evolved.

To an increasing and accelerating degree, lights now are being brought into the roles of thematic glue to visually bind a maker's product range, and active advertisement of the maker's brand identity through day- and night-design.
The many lighting functions on an automobile—up to fourteen of them, not counting forward illumination—provide a wide array of opportunities for automakers to display not just a vehicles' familial identity but also its level of lighting technology (and by extension, its level of technology overall).

LED TECHNOLOGIES In Automotive Exterior Lighting
Tuesday, 30 June 2009

LEDs present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. However, they are relatively expensive, require more precise current and heat management than traditional light sources.

Applications of LEDs are diverse. They are used as low-energy indicators but also for replacements for traditional light sources in general lighting and automotive lighting.
This report presents all information needed on automotive lighting LED.

In the first part, LED sources are presented:
History, Electronic and Optics management, Technologies, Benefit of the technology, Worldwide players with different strategies and the future of LEDs .

DRL as brand signature
Tuesday, 14 April 2009

DRLs — Daytime Running Lamps — are front lights switched on automatically to make vehicles more conspicuous during the day. Vehicles with DRLs can more easily and accurately be seen than those without. DRLs were first required in dark Nordic countries in the 1970s, and various countries round the world have required various types of daytime running lights since then. In the European Union all new passenger vehicles and small vans will have to be equipped with DRLs from February 2011 on; trucks and buses will follow in August 2012.

The DRL has historically been implemented wholly on basis of performance to meet prevailing regulations, with no styling or design aspect beyond basic integration into the vehicle. Rapidly evolving light technology (LEDs, light guides, etc.), the transition of DRL rules from the individual jurisdiction level to a pan-European requirement, and increased emphasis on minimising power consumption are all acting to make the DRL into a strong lever to differentiate the vehicle brand identity.

Flagship of the BMW range, the new 7 Series is a first car to include such an astonishing number of DA and lighting system innovations.

The DA (driver assistance) systems featured for the first time — and exclusively — in the new BMW 7er include:

- Pedestrian detection system with a new Night Vision and FIR camera
- Three functions from one camera: Lane Departure Warning, High Beam Assist, and Speed Limit Info
- Adaptive Cruise Control with Stop & Go
- Parking Assistance
- Lane Change Warning
- Rearview and sideview camera systems
- Enhanced Emergy Call function

Because technologies are changing very fast in automotive lighting and driver assistance systems,
Because industries are searching to optimize research costs,
Because technology is an important lever to increase image and business,
the relationships between universities and automotive vision industries are becoming more and more important.

Regulation report

The target of this report is to demystify and to clarify the content of thousands of regulation pages about automotive front lighting including the latest chapters about AFS and LED new technologies.

The author presents in the first part, how regulations are built and what are the organizations involved in building regulation processes.

- For ECE: GTB, GRE, WP29
- For US: SAE, FMVSS108

Headlamp Adjustment Survey
Tuesday, 25 November 2008

Download full report...

Definitions and related interaction and philosophy of glare and visibility, Luminance, Illuminance and other technical terms are presented with discussion of relationships among seeing distance and glare.

The influence of vertical and lateral aiming on glare and visibility is examined in detail, considering various hypotheses on roads and measurement of glare and visibility.
Eight pilots illustrate the interaction of increasing glare and decreasing visibility.

Aiming regulations and practices in different countries like Germany, France, USA and Japan are described in detail. A synthesis on aiming operation result is presented with the five main points to be retained.

Bulb Replacement Survey
Tuesday, 26 August 2008

Download full report...

Numerous recent trends in the design and construction of vehicles and headlamps can tend to make headlight bulb replacement very difficult.
The range of bulb replacement ease or difficulty is larger than ever before. In some cases, the labour to replace the bulb is much more costly than the bulb itself.
The relative predominance of particular headlamp bulb types differs in Europe, Japan, and North America.
Some bulb types have mounting bases with built-in weather sealing, while others require separate external sealing provisions.

Four grades are proffered to assess the ease or difficulty of bulb replacement, and 70 new vehicles are ranked according to these criteria.
The results are analysed and discussed in the context of applicable regulations.
Only 20% of the car’ headlight bulbs can easily be replaced on the road at night.

The benchmark is presented with the 3 car makers that take in account the bulb replacement operation.

Specific tactics for improvement are suggested for automakers, lighting suppliers, and bulb makers.

Eighty images illustrate the practical issues with bulb replacement, and end users’ and garages’ comments are quoted.
