  • Patent number: 4843527
    Abstract: A matrix lamp bank display utilizes individually removable light filtering assemblies that are composed of a rectangular tinted lens and a supporting frame. Each frame is removably mounted to the display at the front of the lamps provided within it. Each lens is inclined from the vertical to reduce sun or external lighting glare. Provision is made to accommodate thermal expansion of the lens and its supporting frame, as well as ventilation of each lens during lamp operation. Multicolored displays can be achieved by grouping two or more lens colors and operating multiple lamps in combination to project a desired color mix about the matrix.
