摘要： A lens assembly includes plural lens components. A first lens element of the first lens component is aspherical and plastic, disposed on a side of a screen surface, for adjusting focus in image projection to the screen surface. A first lens barrel holds the first lens component. A second lens barrel holds a second lens component. A stationary barrel movably contains the second lens barrel. The second lens barrel is rotated helically relative to the stationary barrel, to adjust the focus for the plural lens components. Thereafter the first lens barrel is rotated helically relative to the second lens barrel, to correct image distortion for the plural lens components, and also to adjust a rotational position of the first lens element. So a gate mark on an edge portion of the first lens element is offset from an effective projecting region of the image projection.

摘要： An illumination apparatus is provided with an LED array including a plurality of LEDs and a second lens array including a plurality of lenses. The LEDs and the lenses are arranged in lengthwise and crosswise directions and aligned such that a relationship between a number of the LEDs and a number of the lenses are mutually prime with each other in both lengthwise and crosswise directions. Primary illumination light from the LED array is split into a plurality of pieces of secondary illumination light by the lenses and thereafter superposed to irradiate. All of pieces of the secondary illumination light are provided with different strength peak positions of the illumination light and therefore, light having a uniform intensity can be irradiated to an irradiated region.

摘要： A reflective optical system for projectors comprises a single integral piece of transparent optical molding having at least an incident surface, an exit surface, and two or more internal reflection surfaces between the incident surface and the exit surface, each reflection power having a power, positive or negative. The reflective optical system is provided with grooves, desirably blackened grooves, formed between the internal reflection surfaces so as to block out undesirable light proceeding therein. The internal reflection surfaces are formed by coating an aluminum film on an outer wall of the transparent optical molding. The reflective optical system reflects incoming image bearing light through the incident surface on the internal reflection surfaces in turn and projects the image bearing light through the exit surface so as thereby to project an image on a remote screen.

摘要： A rotary optical filter apparatus containing an optical filter is integrated with a sirocco type cooling fan having a plurality of fan blades. The cooling fan is supported by a rotary holder of the optical filter apparatus so as to be integrally rotatable with the optical filter. The cooling fan inhales an air from its center part and discharges thus inhaled air from its outer peripheral part due to an action of the fan blades upon rotating, so as to make an airflow along the filter face and cool the optical filter.

摘要： A liquid crystal projector for full-color image projection has three LCD panels as light valve device, associated with respectively primary colors, for displaying an image in a color-separated manner. An ultra high pressure mercury lamp illuminates the LCD panels through three illuminating light paths associated with respectively the primary colors. A combining prism combines image light of the primary colors from the three LCD panels, to obtain full-color image light. A laser diode emanates auxiliary illuminating light of a red color among the primary colors according to laser emission, to compensate for shortage in light intensity in the red color. A ferroelectric shaking or vibrating device vibrates the laser diode, to keep visual noise inconspicuous in the auxiliary illuminating light.
