info
PUYL is a bicycle pump and portable light combined in one device. It is the first permanent illuminating bicycle light which does not need a battery. This combination provides an unlimited light source and a bicycle pump for urban cyclists. The idea is based on Faraday's law of induction. Instead of batteries, it uses electromagnetic induction. The electricity is generated by moving the compressor/ magnet through the two copper coils that are located around the inner compression tube. The light’s battery is charged while pumping.
The generated energy is stored in a rechargeable battery/ super cap. The light source is an ultra bright LED bulb. The magnetic recharge method allows the LED light to be recharged unlimited times.
The criteria for the object required it to be eco friendly and reduce the number of items the user had to carry around.
A patent pending is submitted for this project.
