The luminous enclosure functions as a cage for the light source, eliminating any type of glare.
The skeleton of the lamp is composed of a system of aluminium ribs organized in sequence. This blade structure functions simultaneously to eliminate glare, to reflect the central light source, and to allow heat to disperse. The blades, in different sizes, are cut out of a single sheet of aluminium: in the development phase prototypes were made by chemically photoengraving the sheets, while in the industrialization phase mechanical cutting techniques were used.
A series of colored filters in polycarbonate housed at the sides of the bulb create infinite possibilities of chromatic variation of the body of the lamp, keeping the central light white in color: the rays of 'colored' light are intercepted by the surface of the single blades, without reaching the eye of the observer.
The blade structure interferes with perception of the luminous body according to the standpoint: seen from the front, the fixture looks transparent, while from the side it is perceived as a continuous body.
