    摘要： The present invention is directed to a light housing installed in close proximity to a light source. The light housing has a shield and an attachment arm for securing the shield. The attachment arm allows the shield to be removably attached in close proximity to the light source. The housing optionally has an aperture allowing the housing to be installed over and/or around the light source. The housing at least partially blocks light emanating from a light source, such as an in-ground staked floodlight, and keeps the light from shining directly into the eyes of a person observing the light source. The housing also hides the unsightly components of a light source.

    摘要： A thin, flexible film made of a transparent polymeric material including a structured surface and an opposite smooth surface, wherein light striking either surface, within certain angular ranges, is totally internally reflected. The structured surface includes a linear array of miniature substantially right angled isosceles prisms arranged side-by-side to form a plurality of peaks and grooves. In addition, the perpendicular sides of the prims make an angle of approximately 45.degree. with the smooth surface, and when the film is curled the smooth surface lies in a smooth continuous arcuate curve without materially affecting the performance of the film. Because of the film's flexibility and its ability to totally internally reflect light, it may be utilized in a variety of ways, for example, as a collector of solar energy or as a light conduit. The performance of the film may be manipulated to permit controlled light leakage.
