Optics, PVs Work Together for Full-LED Headlamps PDF Print E-mail
Monday, 14 June 2010
Docter Optics, who for many years have produced a substantial proportion of the condensing lenses at the front of most makers' headlamp projectors, offer precision-moulded optical components, special-purpose lenses and optical subassemblies for many industries.

For example, the optical glass light pipes used in concentrated photovoltaic (CPV) systems concentrate and homogenise sunlight before it reaches the surface of the solar cells, which makes CPV systems up to 40% more efficient than conventional photovoltaic systems.

Since these systems are designed for a long service life, components must be essentially maintenance-free and exceptionally durable. Optical glass eliminates the risk of cloudiness found with many polymers, and Docter also provide production of the required free-form-components in industrial quantities.

These same capabilities will also be important when it comes to producing the all-LED headlights of the future, for the life of the free-form-lenses that are used will have to match the exceptionally long service life of high-quality LED light sources.

In the case of CPV power plants, the optical component must uniformly concentrate the rays of the sun on the surface of the solar cell, but the automotive light of the future will have to do exactly the opposite: headlamp LEDs have to project a precise pattern of light onto the road in compliance with legal regulations by using aspheres, free-form lenses or optical arrays.

For automobile designers, three things are critical:
- The high level of functionality required of headlights, especially when LEDs are used as the light source .
- The design that gives headlights a unique look to ensure immediate brand recognition.
- The engineering to achieve a perfect combination of parameters such as power consumption, weight, packaging depth and service life.

To achieve these lighting needs, glass lenses must have a crystal-clear transparency throughout the entire product life, optimal focus and sharpness of the cutoff line through precision surface texturing, a precise distribution for low beam, high beam and daytime running light functions, high temperature stability with a consistently uniform optical performance, and must also facilitate economical production of even the most complex geometry for freedom of design.

VISION Congress: Final Preparations PDF Print E-mail
Monday, 07 June 2010

The Steering Committee of VISION 2010 has met, with all members present from Renault, PSA, Valeo, Inrets, SIA and DVN. The main target of this meeting was to build the program of the 2-day congress.

34 lectures will be presented. The first day will be focused on lighting technologies, mainly LED, Xenon, AFS/Adaptive lighting, and visibility/glare.

The second day will be focused on Driver Assistance technologies, tools and functions.

Speakers from Finland, Germany, Italy, Japan, Korea, Sweden, Switzerland, The Nederlands, USA, and France will be present.

The official invitation of VISION congress will be sent June 25, 2010 to all lighting experts from car makers, lighting suppliers, universities and labs.
The congress will be held at Versailles, October 7-8, 2010 and the night drives will be held on a private circuit at Satory close to the congress location October 7 from 8pm.

20 demonstration cars will be presented with the latest technologies of lighting and driver assistance.

Make a note on your agenda and book those 2 days. 2010 VISION Congress will be a landmark as the first post-crisis automotive lighting expert meeting. And don't forget, the exciting Paris Mondial motor show takes place in this period, too.
Driving Vision News will regularly publish information of this congress, information on the lectures, the exhibitions and the night drives.
