6223 S P E C I F I C A T I O N A SURFACE FLOODLIGHT ASSEMBLY ABSTRACT OF THE INVENTION A surface floodlight assembly for use in a heliport light- ing system which provides a wide-angle horizontal beam spread and a very narrow vertical beam spread. A pair of sealed beam high- intensity floodlights mounted in a case with their respective axes at a predetermined angle provide a wide horizontal angle of con- vergence while limiting the vertical angle. The case enclosing the floodlights has a cover including a perimeter marking light which has a lens providing a wide angle of divergence. Mounting tabs are provided on the case for securing it in place and posi- tioning groups of the floodlight assemblies around a heliport pad such that maximum illumination is obtained over a substantial portion of the pad. To minimize glare, a shroud is incorporated into the case limiting the divergence of the floodlight beams to prevent glare. Each floodlight assembly is a complete self- contained unit including a power supply which provides varying selections of brilliance and it can be permanently mounted or be portable.
