Publication number: 20040125602Abstract: 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.Type: ApplicationFiled: July 22, 2003Publication date: July 1, 2004Applicant: Light & Sound Design Ltd., a British corporationInventors: Mark A.

Publication number: 20040061926Abstract: A special record format used for commanding light pattern shapes and addressable light pattern shape generator. The command format includes a first part which commands a specified gobo and second parts which command the characteristics of that gobo. The gobo is formed by making a default gobo based on the type and modifying that default gobo to fit the characteristics.Type: ApplicationFiled: August 8, 2003Publication date: April 1, 2004Applicant: Light and Sound Design, Ltd., a British corporationInventor: Mark Hunt

Publication number: 20040046514Abstract: A lighting system with a digital micromirror device which forms a digital godo system that is controllable on a pixel level. The device includes a number of sensitive electronic elements. The device is controlled by two different controllers: a digital signal processor which is effectively the number crunching portion, and a controller, which controls the functions of the light. The controller also logs errors into a registery, such as a non-volatile memory. A field programmable gate array is used for a number of purposes, including to form the ports. One of those ports is a tech port, which is used to detect status of the light such as faults.Type: ApplicationFiled: September 8, 2003Publication date: March 11, 2004Applicant: Light and Sound Design, Ltd., a British corporationInventors: Michael Hughes, William Hewlett, Ian Clarke

Publication number: 20030185010Abstract: An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter with three positions is placed between a light source and a DMD. The first position of the shutter is a mask, preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open, allowing substantially all the light to pass. The third position of the shutter is completely closed, blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs can be used in illumination devices without creating undesirable rectangular penumbras.Type: ApplicationFiled: March 25, 2003Publication date: October 2, 2003Applicant: Light and Sound Design Ltd., a British corporationInventors: William Hewlett, Nigel Evans

Publication number: 20020181070Abstract: A digital micromirror device (“DMD”) is used to alter the shape of light that is projected onto a stage. The DMD selectively reflects some light, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed, thereby carrying out image processing effects on the shape of the light that is displayed. One preferred application follows the shape of the performer and illuminates the performer using a shape that adaptively follows the performer's image. This results in a shadowless follow spot.Type: ApplicationFiled: July 16, 2002Publication date: December 5, 2002Applicant: Light & Sound Design, Ltd. a British CorporationInventor: William E. Hewlett
