Abstract

Light fixture having suspension devices (9) for holding and suspending a louvre inserted in the light fixture housing (11). Each suspension device has a carrier (26) for the louvre, which is retained in an upper position by means of a pressure spring part (33) held on the light fixture housing, and from which it is displaceable into a lower position in which it is held on the pressure spring part (33). In its lower position, the carrier (26) can be hung out of the pressure spring part (33) in order to fold up or remove the louvre. <IMAGE>
