Germany - Valeo ( http:// ) unveils a world first: a new technology that will transform lighting and signaling systems. The 3D-effect technology, used in the front and rear position lamps, adds substantial depth to the Perceived image, despite being only 25 mm thick.
It is based on the principle of the multiple reflection of light from LEDs and opens up significant new styling possibilities.
Valeo has equipped the D09 concept car with this technology. The delicate appearance of the rear lamp is enhanced by a trompe-loeil effect, the result of considerable research. The design teams at Citroen and Valeo worked closely together right from the start of the project , to produce front and rear lamps that maximize this technology.
The first stage involved the creation of computer-generated animated images, followed by the fine-tuning of appearance details on a mock-up.
In addition to providing an attractive appearance and the benefits of compactness and high reliability, the use of LEDs in the lighting system reduces electric consumption, since these light sources require far less power than conventional lamps.
A traditional incandescent system requires total lighting and signaling power of around 160 W, generating CO2 emissions of over 5 g/km, whereas LEDs cut CO2 emissions to 1.7 g/km, corresponding to estimated fuel savings of 0.2 l/100 km on average.
The water glass shell process has low cost, simple operation, and low requirements for raw materials. The basic feature of the process is the use of paraffin-stearic acid low-temperature mold material, and the use of water glass as the binder in the process of shell making. In terms of shell process, its surface quality is average, and its dimensional accuracy is not as high as that of silica sol process, but because of its unique cost, it is widely used in some civil and low-precision internal combustion engines in my country.
