    摘要: The system captures and concentrates sunlight for transmission to interior spaces or to a PV system. A solar collector uses arrayed refractive lenses, opposing concave focusing mirrors, and a movable coupling sheet forming part of a lightguide. The lenses and mirrors have an asymmetric shape, such as having aspect ratios of 3:4 or 1:2, so as to have an asymmetric aperture to better receive light at the different ranges of angles of the sun's rays over the course of a year. The long axis of the apertures is generally oriented in an East-West. The movable sheet contains small angled mirrors, and the sheet is translated to position the angled mirrors at the focal points of the sunlight for maximum deflection of the sunlight to an output of the collection system. A position sensor provides feedback regarding the position of the angled mirrors relative to the focal points.

    摘要: A mechanical actuation system for a light fixture that allows for translation of an array of optics relative to an array of light sources in a defined plane. The system can prevent undesired movement such as rotation or out-of-plane motion. A simple and intuitive user interface enables a user to point a resulting light beam in a desired direction without requiring an understanding of the internal mechanical system. The user interface may include a manually manipulated touch point such as a joystick, knob, or other interface.

    FIG. 5 is a top view of the design of FIG. 1.
    FIG. 6 is a right side view of the design of FIG. 1.
    FIG. 7 is a left side view of the design of FIG. 1.
    FIG. 8 is a perspective view of a second embodiment of a light fixture.
    FIG. 9 is a view of the front face of the design of FIG. 8.
    FIG. 10 is a perspective view of a third embodiment of a light fixture.
    FIG. 11 is a view of the front face of the design of FIG. 10.
    FIG. 12 is a perspective view of a fourth embodiment of a light fixture.
    FIG. 13 is a view of the front face of the design of FIG. 12.
    FIG. 14 is a perspective view of a fifth embodiment of a light fixture; and,
    FIG. 15 is a view of the front face of the design of FIG. 14.
    The light fixture has a switch and apertures located along a front face thereof.
    The design(s) encompass at least six (apertures) but not necessarily a fixed number of apertures. In other words, there may be more than six apertures for these designs.
    The portions shown in dashed lines in the figures form no part of the claimed design. The dot-dash broken line and the dashed broken line immediately adjacent to the shaded surfaces form an unclaimed boundary of the claimed design.
