Abstract: An LED or incandescent light source is positioned in a reflector arranged to reflect light from the LED or incandescent light source which is radiated from the LED or incandescent light source in a peripheral forward solid angle as defined by the reflector. A lens is disposed longitudinally forward of the LED or incandescent light source for focusing light into a predetermined pattern which is radiated from the LED or incandescent light source in a central forward solid angle as defined by the lens. The apparatus comprised of the combination projects a beam of light comprised of the light radiated in the central forward solid angle and peripheral forward solid angles.

Abstract: The invention is a modular ambient lighting system for providing lighting to the interior of the building. The system features three separate modules: (1) a support module, (2) a power module, and (3) a light fixture body module. The support module provides an electrical connection to the building and structural connection to the ceiling of the building. An interchangeable power module fits into a recess or “foot print” in the support module. The power module includes the electrical components of the lighting system (e.g. ballast, transformer, emergency batteries, etc). An interchangeable light fixture body module houses the lamp that can be configured to deliver direct, indirect, or direct/indirect illumination. The interchangeable features of the modules offers superior flexibility because of the ease to reconfigure the electrical operation of the light system, the type illumination delivered, or the aesthetics of the light system.

Abstract: A zoom lens system includes a motor driven lens assembly that is movable on a track in a normal movement range for adjusting the light beam range angle of a luminaire. A pair or doors are pivoted to opposite sides of the frame of the lens assembly and are normally biased to an inactive position where the doors are parallel to and outside of the light path in the luminaire. The doors hold optical media such as diffuser gels. The lens assembly can be moved beyond the normal movement range to an actuation position where projections on the doors engage actuation abutments adjacent the track to move the doors to an active position overlying the lens with the optical media in the light path. A latch holds the door in the active position. The lens assembly can be moved beyond the actuation position to a deactivation position where a deactivation abutment releases the latch freeing the doors to return to the inactive positions.

Abstract: The liquid crystal display device has red, green, and blue LEDs, each emitting a different color light, as a light source. An acrylic lens is mounted on the emission surface of the LED to change angular distributions of light from the LED. The shape of the acrylic lens varies depending on the color of the LED. The angular distribution of emitting light thereby differs by the color of LED to cancel out wavelength dependency of transmittance at each viewing direction in a liquid crystal panel.

Abstract: A light source is disposed in a cavity in an enclosure that supports a part of the wall. The enclosure may be disposed substantially within the wall, such that the enclosure does not provide an obstacle to those moving near the wall. Because the enclosure is capable of supporting a part of the wall, the enclosure may be substituted for one or more substructures of the wall, including, but not limited to, concrete blocks, cement blocks, bricks, cinder blocks, and combinations thereof. The enclosure may be disposed at most any height in the wall.
