    • A lighting fixture (1) projects a light beam for spot lighting in theater stages, cinema and television studios and the like. The fixture includes a light source (20) at one end of a housing (25) having a light beam exit aperture (24) at the opposite end thereof, the light source and aperture being arranged generally concentric with a longitudinal or optical axis (19) of the lighting fixture. One or more beam-shaping blades (30,31,32,33), and preferably also other light beam influencing elements, such as one or more lenses (22,23), an iris (28), and/or a pattern or gobo (29), are arranged along the path of the light beam along the longitudinal axis through the housing from the light source to the aperture. The position of the beam-shaping blade or blades, and preferably of all the light beam influencing elements, is adjustable relative to the longitudinal axis. The fixture produces a well-defined light beam or light cone with a geometry, angle of conicity and focal point that may be altered manually or by remote control.
    • 照明灯具(1)在剧院舞台,电影院和电视演播室等投射用于点光源的光束。 所述固定装置包括在壳体(25)的一端处的光源(20),所述光源在其相对端处具有光束出射孔(24),所述光源和孔大致与纵向或光轴同心地布置(19) )照明灯具。 一个或多个光束成形叶片(30,31,32,33),并且优选地还包括其它光束影响元件,诸如一个或多个透镜(22,23),光圈(28)和/或图案或 沿着光束的路径沿着纵向轴线从光源到孔径沿壳体布置。 束形成叶片或叶片的优选地以及所有光束影响元件的位置可相对于纵向轴线调节。 夹具产生明确定义的光束或光锥,其几何形状,锥度角和焦点可以手动或通过遥控来改变。
