Definitions

  • the present disclosure generally relates to a method for controlling the beam angle of individual lighting devices in luminaires, specifically to a method relating to providing the coordinated control of the beam spread of LED modules in a wash light.
  • 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 provide control over the functions of the luminaire allowing the operator to control the intensity and color of the light beam from the luminaire that is shining on the stage or in the studio. Many products also provide control over other parameters such as the position, focus, beam size, beam shape, and beam pattern. In such products that contain light emitting diodes (LEDs), to produce the light output it is common to use more than one color of LEDs and to be able to adjust the intensity of each color separately such that the output, which comprises the combined mixed output of all LEDs, can be adjusted in color. For example, such a product may use red, green, blue, and white LEDs with separate intensity controls for each of the four types of LED. This allows the user to mix almost limitless combinations and to produce nearly any color they desire.
  • LEDs light emitting diodes
  • FIG. 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 drive systems and control electronics (not shown).
  • each automated luminaire 12 is connected in series or in parallel via data link 14 to one or more control desks 15.
  • the automated luminaire system 10 is typically controlled by an operator through the control desk 15.
  • a known arrangement for luminaires used in the entertainment or architectural market is that of a wash light or cyclorama light.
  • Such luminaires may be constructed as automated luminaires where the operator has remote control of the output angle of the emitted light. It is well known to design the optical systems of such automated luminaires such that the output angle of the emitted light beam can be adjusted over a range of values, from a very narrow beam to a wide beam. This beam angle size, or zoom, range allows the lighting designer full control over the size of a projected image, pattern or wash area.
  • the Robe Lighting CitySkape 48 is an example of such a luminaire with an array of 48 LEDs arranged as 12 light modules each containing a red, green, blue, and white LED. It is possible with such an LED luminaire to change the beam angle of every light module together using a single mechanism.
  • the Robe Lighting Robin 600 LED Wash contains 37 LED light modules which may be simultaneously altered in beam angle from 15° to 60°.
  • none of the prior art examples allow coordinated and separate control of the output angles of the individual light modules. Such ability would be advantageous, as it would allow the combined light beam formed from the mixing of the light output from the LED modules to be shaped and controlled.
  • the present disclosure generally relates to a method for controlling the movement of LED devices in luminaires, specifically to a method relating to allowing both synchronized and independent movement of LED light modules in a light curtain or other LED luminaires.

  • Luminaire 100 is fitted with a linear array of a plurality of light-emitting modules or assemblies 22, 24, 26, 28 and 30.
  • 25 light-emitting sub-modules 20 are grouped and mounted within the modules or assemblies 22, 24, 26, 28 and 30 (five sub-modules per module form a square array.)
  • the luminaire head 110 serves as a common carrier to carry the light-emitting modules 22, 24, 26, 28 and 30 in a side-by-side linear arrangement so that the 25 light-emitting sub-modules 20 (5 submodules per module) form a square arrangement in luminaire 100.
  • Each light-emitting sub-module 20 emits collimated and controlled light beams.
  • Each of these light beams may be individually adjusted for color, by adjusting the output mix of its LED emitters.
  • Each light-emitting module 22, 24, 26, 28, and 30 comprises a row of five light-emitting sub-modules 20. Although a five by five array of light-emitting modules is shown here, the disclosure is not so limited and any shape or size of array of light-emitting modules may be used.
  • the luminaire head 110 may be articulated, as is well known in the prior art, to be capable of a global tilting and panning motion through motors and motor drivers which are controlled by an operator through the data link 14.
  • the luminaire head 110 may be articulated via gimbal mechanism with a base 122 that can rotate the arms 124 about one axis, and arms 124 can rotate the luminaire head 110 about another axis.
  • Other mechanisms for redirecting the light emitted by the luminaire head 110 are also contemplated and with the scope.
  • FIG 3 illustrates the beam angle control system of the light-emitting modules in the embodiment illustrated in Figure 2 .
  • Each of the optical light-emitting modules 22, 24, 26, 28, and 30 mounted in housing 34 is capable of being independently moved in the direction shown by arrow 32.

  • the LED light-emitting modules are normally fixed to and stationary with respect to the luminaire housing 34 while the optical modules move towards and away from the light-emitting sub-module(s).
  • Figure 4 illustrates schematically a side view of an embodiment of the beam angle control system of the light-emitting modules in the luminaire head 110 (not shown in Figure 3 ).
  • Optical module angle control system 222 is actuated by motor 223, which is capable of moving optical module angle control system 222 into and out of luminaire housing 34, as indicated by arrow 32.
  • motor 225 actuates optical module angle control system 224
  • motor 227 operates optical module angle control system 226,
  • motor 229 actuates optical module angle control system 228, and motor 231 actuates optical module angle control system 30.
  • Motors 223, 225, 227, 229, and 231 may be stepper motors, servomotors, linear actuators, solenoids, direct current (DC) motors, or other mechanisms as well known in the art.
  • the motors work by driving a worm gear.
  • motor 223 drives worm gear 221.
  • Other mechanisms for actuating the desired movement are also contemplated.
  • a single motor and worm gear pair actuator is shown here for each optical module angle control system, in practice an optical module carrier covering a row or plurality of light-emitting modules may utilize more than one actuator operating in coordination to actuate the optical module angle control.
  • Figure 5 illustrates schematically the lens system of the light-emitting modules in an embodiment of the disclosure.
  • Optical module angle control system 222 may contain a number of optical assemblies, one for each associated light-emitting sub-module.
  • each optical assembly comprises a first lens 36 and a second lens 38.
  • First lens 36 and second lens 38 are attached to the angle control system 222 and move with it in a fixed relationship to each other.
  • the disclosure is, however, not so limited, and further embodiments may contain different numbers and types of lenses or other optical systems as well known in the art.
  • further embodiments may utilize systems where the relationship of first lens 36 and second lens 38 is not fixed, and can alter.
  • Lenses 36 and 38 may be meniscus lenses, plano convex lenses, bi-convex lenses, holographic lenses, or other lenses as well known in the art.
  • Lenses 36 and 38 may be manufactured from glass, acrylic, polycarbonate, or any other material known to be used for optical lenses.
  • Lenses 36 and 38 may be single elements or may each be lenses comprising a plurality of elements. Such elements may be cemented together or air spaced as is well known in the art.
  • Lenses 36 and 38 may be constructed so as to form an achromatic combination. Such a configuration may be desirable such that the differing wavelengths of light from the associated LED light-emitting module do not diverge or converge from each other and remain mixed. The design of such achromatic lenses or lens assemblies is well known in the art.
  • a light-emitting module of the system comprises an LED 42, which may include a primary optic, mounted on substrate 43.
  • LED 42 may contain a single color die or may contain multiple dies, each of which may be of common or differing colors.
  • the light output from the dies in LED 42 enters light integrator optic 44 contained within protective sleeve 40.
  • Light integrator optic 44 may be a device utilizing internal reflection so as to collect, homogenize and constrain and conduct the light to exit port 46.
  • Light integrator optic 44 may be a hollow tube with a reflective inner surface such that light impinging into the entry port may be reflected multiple times along the tube before leaving at the exit port 46.
  • Light integrator optic 44 may be a square tube, a hexagonal tube, a heptagonal tube, an octagonal tube, a circular tube, or a tube of any other cross section.
  • light integrator optic 44 may be a solid rod constructed of glass, transparent plastic, or other optically transparent material where the reflection of the incident light beam within the rod is due to total internal reflection (TIR) from the interface between the material of the rod and the surrounding air.
  • the integrating rod may be a square rod, a hexagonal rod, a heptagonal rod, an octagonal rod, a circular rod, or a rod of any other cross section.
  • each LED 42 may comprise a single LED die of a single color or a group of LED dies of common or differing colors.
  • LED 42 may comprise one each of a Red, Green, Blue, and White LED die.
  • LED 42 may comprise a single LED chip or package while in yet further embodiments LED 42 may comprise multiple LED chips or packages, either under a single primary optic or each package with its own primary optic.
  • these LED die(s) may be paired with optical lens element(s) as part of the LED light-emitting module.
  • LED 42 may comprise more than four colors of LEDs. For example seven colors may be used, one each of a Red, Green, Blue, White, Amber, Cyan, and Deep Blue/UV LED die.
  • Light integrator optic 44 may advantageously have an aspect ratio where its length is much greater than its diameter. The greater the ratio between length and diameter, the better the resultant mixing and homogenization will be. Light integrator optic 44 may be enclosed in a tube or protective sleeve 40 that provides mechanical protection against damage, scratches, and dust.
  • the light integrator optic 44 may have entry ports and exit ports that differ in shape.
  • a square entry port and an octagonal exit port 46 may have sides which are tapered so that the entrance aperture is smaller than the exit aperture.
  • the advantage of such a structure is that the divergence angle of light exiting the light integrator optic 44 at exit port 46 will be smaller than the divergence angle for light entering the light integrator optic 44.
  • the combination of a smaller divergence angle from a larger aperture serves to conserve the etendue of the system.
  • a tapered light integrator optic 44 may provide similar functionality to a condensing optical system.

In the position shown in Figure 6 , where first lens 36 and second lens 38 are at their furthest separation from the light-emitting module and the exit port 46 of light integrator optic 44, the emitted light beam will have a narrow beam angle.
  • the emitted light beam will have a wide beam angle.
  • Intermediate positions of the lenses 36 and 38 with respect to exit port 46 of light integrator optic 44 will provide intermediate beam angles.
  • the range of beam angles from the system may be adjusted from 4° to 50°.
  • each row of optical light-emitting modules 22, 24, 26, 28, and 30 may be individually and separately adjusted for beam angle.
  • light-emitting module 30 may be in a wide-angle position, light-emitting module 28 in a slightly narrower position, light-emitting module 26 narrower again, while light-emitting modules 24 and 22 are in the narrowest angle position.
  • Such a configuration may be useful for lighting a cyclorama or backing where light-emitting module 30, with its wide angle, is lighting areas of the backing that are close to the luminaire 100, while light-emitting module 22, with its narrow angle, is lighting areas of the backing that are distant from the luminaire 100.
  • Such an arrangement will provide even and adjustable lighting of the backing.
  • the operator may be provided with individual control of the light output from the LEDs in each of the light-emitting sub-modules 20. In conjunction with the beam angle control afforded by the movement of the optical module carriers, this allows interesting and unusual lighting effects to be created.

  • the second light-emitting sub-module additionally has a lighting effects system.
  • This lighting effects system comprises optical effect 62 that is rotatably mounted in effects carrier arm 60 such that it can rotate as shown by arrow 64. This rotation is effected through motor 50 and pulley system 58. Additionally, the effects carrier arm 60 may be swung into and out of position through motor 52, pulley system 54, and belt 56. Through operation of motor 52, optical effect 62 may either be positioned across light exit port 46e or moved away from light exit port 46e and out of the light beam so that it has no effect.
  • lenses 36e and 38e may be moved in a direction, as shown by arrow 32, as before to alter the beam angle of the light beam, now further modified by optical effect 62.
