Signal Lamp System - Vertical Linear Technology 1999-01-0391

A change in styling towards increased headlamp height has been evoked in the paper “Vertical Complex Shape : a new breakthrough in lighting technology”. A trend also exists towards vertical elongation of rear lamps.
This increasing demand by designers is leading to rear lamps containing vertical functions in which the height is significantly greater than the width. For these shapes the ratio between the width and the height is generally between 1 to 5 and 1 to 10.
At the same time car makers are currently requesting suppliers to improve the homogeneity of the illuminated appearance of rear lamps
Conventional solutions are not really suitable for these elongated shapes. They suffer from a lack of homogeneity with respect to their illuminated appearance. Moreover they are often too deep to fit into the bodywork
The optical system presented here controls the direct flux of an incandescent bulb and can be used for tail/stop lights and turn indicators.
The dimensions that can be achieved are between 18-45 mm wide, depending on the function, and up to 400 mm high.
