US Patent:

6412972, Jul 2, 2002

Filed:

Dec 10, 1999

Appl. No.:

09/458603

Inventors:

Roger A. Pujol - Mohegan Lake NY
Thomas P. Tyler - Wallkill NY

Assignee:

Altman Stage Lighting Company - Yonkers NY

International Classification:

F21V 2128

US Classification:

362272, 362269, 359292, 352198

Abstract:

There is provided a digital light projection apparatus for projecting digitally selected light beams onto a stage display to create the effect of a continuously moving image. The apparatus has a fixed housing with a luminaire and a deformable micromirror device and a rotatable housing with a fixed mirror and a rotatable mirror. The deformable micromirror device directs selected light beams generated by the luminaire to the fixed and rotatable mirrors for projection to a stage display. Color may be achieved by use of color wheels, chromatic prisms, and/or lasers.

International Classification:

H04N 574

US Classification:

348771, 348744, 348770, 472 57, 362368

Abstract:

A light display system for projecting digitally generated light beams onto a stage display, comprising a housing rotatable about at least one axis, a deformable mirror device (DMD) having a surface comprising an array of deformable mirror cells, the DMD being mounted in the housing, a light source mounted in the housing for directing a light beam in an optical path that impinges upon the surface of the DMD, and digital control signals to the DMD for digitally activating selected deformable mirror cells of the DMD to reflect digitally selected light beams onto the stage display having the optical effect of a continuous moving image or images. The housing is rotatable about a second axis transverse to the first axis. Coloring devices can be mounted in the housing.

Appl. No.:

10/286727

Inventors:

Thomas Tyler - Wallkill NY, US
Jonathan Connell - Hawley PA, US

International Classification:

F21V007/00

US Classification:

362/297000, 362/347000, 362/346000, 362/348000

Abstract:

A luminaire for providing wide-angle illumination has a housing with an open side and an arcuate reflector with a reflecting surface that defines a plane of substantial symmetry. This reflecting surface is mounted within the housing and arranged to orient the reflecting surface towards the open side and has first and second reflector portions that are substantially mirror images of each other in relation to the plane of symmetry. The reflecting portions define a focal axis that is normal to said plane of symmetry and formed of a plurality of a substantially elongate reflecting facet surfaces or a series of reflector strips each of which is substantially parallel to the focal axis, the arcuate reflector having asymmetrical cycloidal cross sections in planes substantially normal to the focal axis, and the reflector portions forming an indentation or cusp in the direction of the light source at the point where they meet along the plane of symmetry at least in the region of the focal axis. The luminaire additionally has a light source mounted centrally along the focal axis, which provides both a direct light output and a reflected light output through the open side, forming a substantially uniform beam for a predetermined distance in a direction substantially parallel to the plane of symmetry.

International Classification:

F21K002/00

US Classification:

362648000

Abstract:

A LED luminaire track lighting system includes an elongate track, having a number of longitudinal guideways, for attachment to a support surface, as well as a number of current conductors arranged within at least some of the guideways. The first of these conductors are power conductors and the second conductors are data conductors, the conductors being electrically isolated from each other. The lighting system further contains a first adapter for connection to a source of electrical power for the power conductors, and a second adapter for connection to a source of control data for application of data to the data conductors. There is at least one LED color-changing luminaire present in the system, and this luminaire contains a number of LEDs, each of which, when energized, generates a single color out of a discrete plurality of colors. A data converter converts data along the data lines to control the currents in the individual groups of color LEDs so that they create a desired composite color. Further, at least electrically, the LED color-changing luminaire is at least electrically connected to the power conductors and data conductors in the track.

International Classification:

F21V 900

US Classification:

362277

Abstract:

Color wheel for lighting fixture, which includes a polygonal metal plate, which has slotted metal bars seated on the side edge of the polygonal plate with rectangular glass plates, e. g. dichroic filters adhesively held in the slots of the metal bars spaced. The glass plates are not in direct contact with the metal bars and are spaced close to each other, but not in contact, in a peripheral array.
