Intra Salon translates a lighting object into a lighting effect and a programme-defined room into a spatial atmosphere. The prismatic show cases, measuring 2.0m x 2.2m x 2.6m, are set in the space of the salon so as to conduct the visitor's path around the salon. The cases are movable and adapt to the activities and occasional events at the salon. Instead of lighting objects, the prisms rather display lighting effects, with which the desired atmospheres in a room are established. The lighting effect is the result of several factors: the choice of the right fixture as well as the structure, colour and temperature of the room. Its appearance and degree of efficiency depend, of course, on the knowledge and experience of the lighting engineer. The spatial atmospheres established through the lighting effects are no longer tied to the programme in a particular area; a similar atmosphere can therefore pervade the bathroom but also the working area.
