Electronic road beacon |
摘要 |
An electronic road beacon is provided with a flashing light. The beacon functions as a traffic alert device by being placed on the surface of a roadway or other surface. Accordingly, the beacon is designed to withstand the impact of a car, truck or other vehicle which may strike or run over the beacon. The beacon comprises three essential components. The first is a circular base plate having a raised annulus around the periphery which defines an interior opening and a bottom portion. The second component is a dome comprising a spherical lens having internal concentric radial freznel and at least one reflector mirror. The dome is mounted to the base plate and define a sealed interior space that is protected from weather and other harmful conditions. The third component is a circuit board that is mounted to the bottom portion of the base plate in the interior space of the beacon. The circuit board contains solid state circuitry and a light emitting bulb. The light is focused and intensified by the dome. In addition, a magnetic ON/OFF switch is activated by a magnetic key to operate the bulb.
