Light Modifier Patents (Class 362/509)
  • Patent number: 6352359
    Abstract: A vehicle light assembly includes a lens cover from which light emanates. A light shaping surface microstructure is carried in a portion of the light assembly. The microstructure can be incorporated into many different surfaces of the light assembly such as a surface of the lens cover, a surface of a macro-optical structure on the lens cover, or on a reflective surface of the assembly. The microstructure homogenizes and directs light emanating from the light assembly via reflection or transmission to provide a smooth, continuous pattern of light having a predetermined distribution shape or envelope and a predetermined directionality.

  • Patent number: 6332696
    Abstract: A lens cover for covering the lens of a traffic signal when the signal is not in service. The lens cover is made of a black polyethylene flat tubing which is cut and sealed on one end and has an open end to fit over traffic light lens shields. The lens cover is completely opaque and thus prevents light from the lens passing through. Thus, motorists are not confused with respect to the traffic light being in an operating state. The lens cover also has an observation hole at the bottom which allows one to check the operation of the traffic light from ground level.
