Abstract

A solar-powered airfield light provides high angle light up to about 90°. A solar panel is mounted atop the enclosure but does not overlie a curved transparent shoulder extending upward from the transparent generally cylindrical side walls of the enclosure. An optical element within the enclosure surrounds an LED light source so as to direct light emanating from the LED in two preferential beams, one directed to the shoulder and the other directed to the side walls. A portion of the light impinging on the curved shoulder is redirected to high angles to comply with high angle light requirements for airfield lights.
