Bright Lighting Idea from Federal-Mogul

With few exceptions—think Nissan cube and Scion xB—one of the downsides of new vehicles for those who are lanky of stature is that when a sunroof is part of the package, headroom is seriously truncated.

With few exceptions—think Nissan cube and Scion xB—one of the downsides of new vehicles for those who are lanky of stature is that when a sunroof is part of the package, headroom is seriously truncated. This is exacerbated in cases where the exterior design has a severely sloping roof characteristic of coupes, now characteristic of coupe-like sedans.

All of which brings us to a new lighting system developed by Federal-Mogul, a new array of ultra-thin LEDs combined with what they’ve named “NovaLens.”

A major benefit of the combination: the possibility of increasing headroom.

That is, according to Ramzi Hermiz, Federal-Mogul senior vp, Vehicle Safety and Protection, “With interior lamp profiles typically 30 mm or more, the size of interior lighting modules has been a limiting factor for vehicle manufacturers.” (And for tall people, too.) “Our new lamp is just 12-mm thick, giving vehicle designers an extra 18 mm of space and increased styling design opportunities.”

The lens is designed such that there is a uniform distribution of light from the LEDs. This means there is even illumination without hot spots.

Additionally, the power draw is small compared with conventional incandescent bulbs: <2 W compared with ~10 W. The LED lamps are not only longer lasting than the incandescent—as much as 10X longer-lived—but they operate significantly cooler, so in the event there is a really tall person a hot head due to lighting is unlikely.
