  • Patent number: 9528679
    Abstract: An optical system includes a lens and reflector configured to form a wide angle beam from light emitted from an array of LEDs by modifying only the component of emitted light that diverges from a reference plane. A central portion of the lens collimates emitted LED light relative to the reference plane containing the optical axes of the LEDs. A peripheral portion of the lens re-directs emitted LED light into an orientation perpendicular to the reference plane. The reflector surrounds the periphery of the lens and re-directs light from the peripheral portion of the lens into a direction parallel with the reference plane. The linear array of LEDs may include sub arrays projecting away from a support plane to enhance visibility of a resulting light signal from vantage points close to or aligned with the support plane.
