Project OSRAM LED LIGHT@DAY –
LED-Daytime running light

The daytime running lamp from OSRAM should be different from existing retrofit solutions (pixels optics).
Then we developed the daytime running lights on the basis of an optical fiber.

• Daytime running lights for retrofit to ECE R87
• The only daytime running lights in the aftermarket with a homogeneous light guide.
• An intelligent controller detects whether the engine is running and the lights switched on automatically.
• Conceptually, the optics design, mechanical design, the control device, the prototype up to the support of the production start, all from one source

Project Third Stop Lamp LED –
Maybach Landaulet

Landaulet is a particular body form of a car. Landaulets are normally made from saloon cars by removing the rear part of the roof and replacing it with a folding top. This means that the driver and front-seat passenger still sit under a hardtop. At Maybach this required integrating a third stop lamp into the boot lid. The development of a specific optical system was required due to the restricted construction space in the rear lid and the design constraint of a narrow light emitting line.

• LED selection and development of an optical system according to ECE R7
• Simulation of the light including photo-realistic rendering
• Construction of a preliminary model for concept validation
• Series construction of the light
• Coordination with tool construction and OEM
• Validation according to test plan
• Certification by the Federal Motor Transport Authority (E1)
• Serial production

Project Roof Module Webasto Hattrick

At the IAA 2005, Webasto showed a Volkswagen Touareg-based concept car. Three independent comfort modules were the focus of this project: an integrated (external) shade including a panoramic roof, a cargo box and a multi-functional rear lid.

RUETZ TECHNOLOGIES developed the cowl at the front cross member and the control panel for controlling light, shade and roof system. By slightly touching the control panel, the roof opens and closes, quickly wiping over the entire panel will open or close the entire roof system and shade system.

• Cowl with interior light and roof controlling functions
• Conceptual design, development, simulation of light distribution, construction and manufacturing (RP)
• Control of interior light and sun roof by non-contact sensors
• Programming of various controller convenience functions for roof and roller blinds
• Close cooperation with the Webasto design team
• Integration into the Hattrick concept car
