HIGH-INTENSITY RADIATION DEVICE

摘要

A compact high-intensity radiation device suitable for use as a light signaling means and for other purposes includes a base, an enclosing envelope mounted on the base and constructed of translucent material together with a cover portion of opaque material mounted atop the envelope to define a housing structure in which a main reflector and a secondary reflector are disposed in coaxial relationship with each other, each of said reflectors having reflecting surfaces of parabolic configuration. A point source of light is mounted at the focus of both the main and secondary reflectors and is surrounded by a hemispherical reflector. All reflectors are supported on the base by means of a plurality of support studs and a cutoff reflector is mounted on the secondary reflector to prevent undesired reflections within a limited segment, the device being generally adapted to direct a cone of light in all remaining horizontal directions and wherein the cone of light may be directed through an angle between a minimum of approximately 2 DEG above horizontal and a maximum of approximately 20 DEG thereabove.
