Definitions

  • the disclosure generally relates to an effects system in an automated luminaire, and more specifically to a system for coordinating multiple effects within an automated luminaire.
  • Luminaires with automated and remotely controllable functionality are well known in the entertainment and architectural lighting markets. Such products are commonly used in theatres, television studios, concerts, theme parks, night clubs, and other venues. A typical product will commonly provide control over the pan and tilt functions of the luminaire allowing the operator to control the direction the luminaire is pointing and thus the position of the light beam on the stage or in the studio. Typically, this position control is done via control of the luminaire's position in two orthogonal rotational axes usually referred to as pan and tilt. Many products provide control over other parameters such as the intensity, color, focus, beam size, beam shape, and beam pattern.
  • Figure 1 illustrates a typical multiparameter automated luminaire system 10.
  • These systems typically include a plurality of multiparameter automated luminaires 12 which typically each contain on-board a light source (not shown), light modulation devices, electric motors coupled to mechanical drives systems, and control electronics (not shown).
  • each luminaire 12 In addition to being connected to mains power either directly or through a power distribution system (not shown), each luminaire 12 is connected is series or in parallel via data link 14 to one or more control desks 15. An operator typically controls the automated luminaire system 10 through the control desk 15.
  • a prism An optical effect that is commonly used in prior art automated luminaires is often referred to as a prism.
  • This is typically a glass or plastic device placed at a point in the optical train such that it converts a single image produced by the beam color, size, shape, and pattern optical systems into multiple beams for display.
  • a linear prism may convert a single beam into a linear array of identical beams.
  • Figures 2 and 3 A diagrammatic example of the effects produced by a prior art prism optical system is shown in Figures 2 and 3 .
  • a single image 20 produced by the beam color, size, shape, and pattern optical systems passes through a prism 21a, resulting in multiple copies of the image 20 as output images 22a.
  • the prism 21a may be rotated as indicated by the arc 23, causing a corresponding rotation in the array of output images as indicated by the arc 24.
  • Figure 3 shows the same optical system and prism 21a, but with the prism 21a rotated to a new position, resulting in a corresponding rotation of the output images 22b.
  • Image 20 is here shown for clarity as a simple circular image, however the image 20 may be any image, complex or simple, as produced by the automated luminaire, in particular it may have a shape defined by patterns or gobos in the optical train.
  • the prism may be different shapes and may be capable of being inserted or removed from the light beam automatically. It may further be possible to select different prisms producing different effects for insertion in the beam.
  • the prior art systems are only capable of introducing a single prism at one time.
  • a coordinated effects system in a first embodiment, includes a first prism system and a second prism system.
  • the first prism system includes a first plurality of prisms, and is configured to position a selected one of its prisms in a light beam passing through the first prism system or to remove all of its prisms from the light beam passing through the first prism system.
  • the first prism system is also configured to rotate at least one of its prisms.
  • the second prism system includes a second plurality of prisms, and is configured to position a selected one of its prisms in the light beam passing through the first prism system or to remove all of its prisms from the light beam passing through the first prism system.

  • the optical device is configured to produce a first image in the light beam.
  • the first prism system includes a first plurality of prisms and is configured to position a selected one of its prisms in the light beam or to remove all of its prisms from the light beam.
  • the first prism system is also configured to rotate the selected one of its prisms to produce a modified image from the image.
  • the second prism system includes a second plurality of prisms and is configured to position a selected one of its prisms in the light beam or to remove all of its prisms from the light beam.

  • the second prism 52 is fitted with a magnet 57 in its periphery that rotates with the second prism 52.
  • a corresponding sensor or sensors such as a Hall effect sensor in second prism system 50 may detect the position of magnet 57, and thus sense the rotational position of second prism 52 at the moment the magnet 57 is detected.
  • first prism system 40 may be fitted with a magnet and sensor or sensors such that the rotational position of first prism 42 is known and communicated to the control system of the automated luminaire 100.

  • both first prism 42 and second prism 52 may be rotated independently, as indicated by arcs 64 and 65, respectively, causing a change in pattern and rotation (as indicated by arc 66) in the output image 63a.

  • the first prism 42 and the second prism 52 may be simultaneously rotated in a coordinated manner, such that the angle between them remains constant.

  • such rotation may be performed without information received from sensors fitted to the first prism 42 and the second prism 52.
  • the sensors fitted to the first prism 42 and the second prism 52 enable the control system of the automated luminaire 100 to maintain improved coordination in the rotation and positioning of the prisms.
  • the first prism 42 and the second prism 52 may be simultaneously rotated in a coordinated manner at differing speeds and/or in differing directions, resulting in output images that change and/or rotate.
