Luminaires are grouped in pairs.

Four points are grouped to form a square.

From eight points on, a circle is formed.

Elements arranged close together are grouped according to the law of proximity and form a pure shape. The example on the left demonstrates that we first see a circle and then an arrangement of luminaires. The circles are arranged in such a strict order that the imaginary linking lines between them is not straight lines, but forms a continuous circle, not a polygon.
