Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servo-motors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.

Abstract: A method and apparatus is disclosed for storing light in which light from a light source passes through a rotary chopping disk and through an entrance slot in a light box where the chopped light is allowed to accumulate over time within a closed portion of the light box. After the storage process is stopped, sometime later, which may be a matter of days, the light source in the box is turned on and the light exiting the light box is detected, with the amount of output light increased over the amount of input light due to the storage of light energy within the light box. The amount of light stored in this manner is proportional to the pulse repetition frequency of the light pulses, with the spinning disk having apertures therethrough. The pulse repetition frequency may be multiplied through the utilization of cascaded rotating apertured disks positioned along the light path between the light source and the entrance slot of the light box.
