FIT LUX has been imagined in order to educate the public about the value of energy. This lamp illuminates a picnic table under the trees farfrom the urban energy network.
To avoid vandalism and to successfully integrate in the mast of the lamp, the generator operates with a linear motion. It consists of a sleeve incorporating powerful ring magnets, which slides on a stainless steel tube. Inside there is a series of coils on soft iron cores.
An energy of about 20 W is created by the movement of magnets in the coils which induce an electrical current. This energy is stored in a battery via a charger. Through an electronic management system, the battery restores as lightthe energy created by the user. This light is generated by a LED with high efficiency (~ 1 W), thereby the power supplied for one minute can illuminate about 15 minutes.
FIT LUX produces 10 lx at full power. By comparison, a sodium lamp provides between 50 and 60 lx.
Like any energy system, a small part of the energy will be lost in heat. The main losses are caused by the generator, the battery (charge / discharge) and in the LED.
To reduce the shock in stops, the movable sleeve is slowed in the ends of the tube by the principle of current brake eddy made by a massive aluminum cylinder placed in the stainless steel tube.
