The present invention relates to a device for simulating fire effects in military or civilian combat training, said device comprising a light source ( 1 ) and means adapted to control a light lobe formed by light beams from said light source. Said means comprises a two-dimensional array ( 3 ) of elements ( 18 ) electronically controllable to assume a selected state among at least a first state of letting through said light inciding thereupon in a main direction of said light lobe or a second state of not letting through said light inciding thereupon in said main direction, and a unit ( 2 ) adapted to control said elements for designing the spatial propagation of said light lobe.
