Patent number: 7401951Abstract: 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.

Patent number: 7393131Abstract: A surface light source (4) includes a light guide plate (2) and a light source (5). The light guide plate has an incident surface (21) and an emitting surface (22). The light source is adjacent to the incident surface of the light guide plate for radiating light beams into the light guide plate through the incident surface. The emitting surface defines a large number of prisms (221), in which the distance (L) separating each two adjacent prisms changes according to an intensity of the light beams received from the light source.
