  • Publication number: 20110210671
    Abstract: Flashing light module for a traffic safety cone has multiple stacked arrays of LED lights providing 360-degree visibility around the cone. The LED arrays are mounted onto a battery container, and a transparent or translucent housing covers the arrays and mounts onto the battery container to provide a water-tight seal for the enclosed electronics. The battery container fits into the upper opening in a truncated traffic safety cone. The LED light arrays have a variable flash rate. Optionally, an ambient light sensor is used to control the intensity of the light produced by the LED lights.

  • Patent number: 7905622
    Abstract: A traffic safety cone incorporating a flashing light module includes electrically coupled first and second modules. The first module includes a solar cell array positioned atop an upper surface of a circular mounting member, a resilient, impact cushioning bumper that surrounds the mounting member, and a high-intensity LED flasher unit having a cylindrical base. The circular disk is secured to the top of the flasher unit, and the cylindrical base fits into the top of a traffic cone that has been truncated for a precise fit. The second module includes a truncated cone-shaped housing, electrical batteries installed within the housing, battery charging circuitry and an ON/OFF switch. The second module and a module retainer plate, which also functions as a battery cover, are installed in that order in the bottom of the traffic safety cone and are secured to the first module with threaded securing rods.
