Starting with an ordinary sheet of drawing paper I did some experiments with folding bellows. The shape is an extruded rhombus. It has a broad and a narrow side. The narrow side saves space & keeps the minimum distance to the lamp, the broad side makes the visual surface bigger which keeps the light softer. The construction of the lamp is a highly improvised solution made out of bicycle pieces for testing the light appearance. It is important to mention that the lamp is a low-power lamp which does not produce any heat.
