The present invention generally relates to an optical system for a wash light and specifically to a variable beam angle system which provides an improved range of beam angles and efficient light output. The present invention includes a light modulating optical element that has a central aperture that can be moved along the optical axis the system. Further the central aperture of the modulating element may be occluded by a diffusing element. The extent of the occlusion can be varied. At a first limit position when the optical system is adjusted so as to provide the minimum beam divergence the light beam will pass through the aperture with no intensity loss. In this configuration the first optical element has practically no effect on the beam. At a second limit position when the optical system is adjusted so as to provide the maximum beam divergence the diffusers cover the central aperture to diffuse the central illumination so as to avoid excessive intensity in the beam centre. The range of beam angles and light modulation can be further improved by means of a variable sized aperature.
The present invention provides a drive system for an optical light modulation system employing multiple light modulation element pairs (205, 215, 206, 216). The each pair is driven by a single motor (209, 219) which drives one axle (228) around which one element (205) of the first pair (205, 215) rotates while the other element (215) of the first pair (205, 215) free floats and rotates about a second axle (228). While the second axle (228) drives the rotation of the first element (216) of the second pair (206, 216) and the first axle (228) provides a rotation pivot for the second element (206) of the second pair (206, 216). Thus the two pairs share the two axles (228) providing a more compact drive system that can be used more flexibly in an optical train of an automated multiparameter lighting system.
The present invention provides a more efficient use of control signal capacity to control multiparameter automated luminaries by remapping channel assignments within a luminaire. The system taught allows parameter mappings to be group for programming convenience. It allows parameters to be skipped and allows flexibility in the resolution allowable for controlling a parameter. It also allow luminaries to share some channel assignments.
The present invention provides an improved paradigm for controlling multicolored LED's in an automated lighting system that is particularly useful for LED fixtures using LED colors other than or in addition to Red, Green and Blue and with LED fixtures used in combination with subtractive (CMY) color mixing fixtures.
