Abstract (en)
[origin: US7217002B2] In a room lighting system ( 1; 27 ), e.g. an architectural lighting system, including two alignedly arranged refractive elements ( 9, 10 ) whose centers are substantially located in the beam axis ( 11 ) of a light source ( 7 ) and one ( 10 ) of which is mounted to be rotatable about said beam axis ( 11 ), also the other refractive element ( 9 ) is mounted to be rotatable about said beam axis ( 11 ), wherein drive means ( 18, 19; 13 to 17 ) plus control means ( 20 ) are associated with to the two refractive elements ( 9, 10 ) for selective rotation in the same sense or in opposite senses, and both of the refractive elements ( 9, 10 ) are prism elements, wherein at least the two refractive prism elements ( 9, 10 ) are arranged in a common housing ( 2; 28 ).
