Drivers spend an average of up to four hours a day in their cars or light trucks, while commercial-vehicle owners spend even more time on the road.
Today, lighting is not a significant factor in the design of most passenger-car and commercial-vehicle interiors, but Hella executives have predicted that the use of ambient LED lighting in North America will more than quadruple over the next five years. "LED lighting technology provides designers with another important way to add value and improve the overall driving experience," said Wambsganss.
Automakers are using single-color lighting to reinforce brand identity and multiple colors to customize and create mood lighting. Different colors have been found to provide a range of emotional responses from excitement to feelings of calm. RGB technology, which allows controlled blending to achieve a wide color spectrum, should prove to be popular in automotive interiors.
Hella's RGB/LIN technology achieves precise color and intensity control using proprietary LED module calibration. In addition to these products, the company offers fabric backlighting, LED overhead consoles and slim-line LED interior lighting (shown).
