A design team from Sichuan University in China has come up with a lighting concept that could potentially have applications in the mountain biking world. It's a handlebar mounted LED projector, which they call Lumigrids, that projects a grid onto the ground in front of the rider. The idea is that changes in the terrain cause the grid to deform, and make it easy spot obstacles. According to the designers, Lumigrids would have three different modes that change the grid size - normal mode (140x180mm), high-speed mode (140x260mm), and team mode (300x200mm).
The concept is intriguing, but could it work for mountain biking at night? Modern lights are so powerful that it doesn't seem that this would be necessary, and the positioning of the grid could also be problematic. Plus, the speeds that mountain bikes reach and the types of obstacles encountered off road are greatly different than what a commuter would encounter on a paved road. Could some kind of hybrid light and grid system work, with the the grid projected further than the range of the beam? It will be interesting to see if this concept goes further than the drawing board.
