摘要： A projection zoom lens system is used in imaging and non-imaging modes for entertanment and architectural illumination, providing 8:1 zoom ratio in an imaging mode and 20:1 zoom ratio in a non-imaging mode. When coupled with a variable aperture iris, beam size control is obtained with 120:1 ratio. The lens system comprises four lens groups: a first group having a positive refractive power, a second group having a negative refractive power, a third group having a negative refractive power, and a fourth group having a positive refractive power. In the imaging mode, the third group is adjusted axially to vary magnification while the second group is adjusted axially to focus on the object. In the non-imaging mode, the second and third groups are brought into close proximity with each other and adjusted axially as a unit to vary magnification. The fourth group remains fixed and the first group can be adjusted axially to focus the image at different throw lengths.
摘要翻译：在成像和非成像模式中使用投影变焦透镜系统进行入射和建筑照明，在成像模式下提供8：1变焦比和在非成像模式下提供20：1变焦比。当与可变孔径光圈耦合时，以120:1的比率获得光束尺寸控制。透镜系统包括四个透镜组：具有正折光力的第一组，具有负折光力的第二组，具有负折光力的第三组和具有正折光力的第四组。在成像模式中，轴向调节第三组以改变放大倍数，而第二组被轴向调节以聚焦在对象上。在非成像模式中，第二组和第三组彼此靠近并且作为一个单位被轴向地调整以改变放大率。第四组保持固定，第一组可以轴向调节，以便以不同的投射长度聚焦图像。

摘要： Architectural luminaries utilize a common optical engine having a lamp coupled to an ellipsoidal reflector, a field stop aperture, and image-projecting lenses A color wheel, gobo wheel, and mechanical dimmer may also be included. A microlens element converts a spotlight optical engine into a wash light optical system. A multiple lens array provides variable diffusion. The optical engine is combined with an X-Y scanning mirror beam direction system in a substantially recessed housing for mounting in the ceiling of a building. The optical engine is combined with a pan-and-tilt yoke for greater range of coverage with an exposed luminaire.

摘要： A stage lighting instrument having a high-intensity light source or lamp coupled with a concave reflector, and a projection optical system having a lens system that includes an aperture stop. The lens system forms a real image of the light source encompassing or near the aperture. A color filter and dimming system may be located within the lens system so that the color filter and dimming elements occupy a volume of space near the aperture stop and within the real image of the light source. By locating the color and dimming apparatus near the aperture stop and within the volume occupied by a real image of the light source, superior color mixing, dimming and integration is achieved using simple, un-patterned filters and a simply-shaped dimmer panel. A color filter and dimming system may alternatively be located as close to the light source as possible so that a real image of the color filter and dimming elements is formed near the aperture stop where the image of the light source is formed. The alternate location, forming a real image of the filters and dimmer, is equivalent to locating the actual color filter and dimming elements at the aperture stop. Diffusion glass elements used in a similar apparatus, located at the aperture stop, transform spotlight properties into wash-light properties in a continuously-variable manner.

摘要： A stage lighting instrument having a high-intensity light source or lamp coupled with a concave reflector, and a projection optical system having a lens system that includes a well-defined aperture stop.

摘要： A high intensity light projector for stage, architectural and similar applications includes a controllable image quality projection gate providing advanced visual effects. The projection gate, capable of selectively scattering or transmitting incident light, may be constructed of any array of scattering liquid crystal material in combination with infrared and ultraviolet reduction means which provide in the high intensity beam, a stable thermal environment by minimizing the absorption of light by the projection gate. Additional thermal efficiency is provided by supplemental cooling means. Color control is also provided in the form of dichroic filter wheels forming cooperating adjustable low, high and band width filters including saturation control. A color measuring feedback sensor is also provided. An intensity measuring feedback sensor controls a spatially-modulated, variable-density, reflectively-coated dimming wheel. A programmable gobo system has provisions for gobo selection, orientation, and rotation.
