LED lighting fixture

An LED lighting fixture including:

• a support structure having a horizontal cross-dimension and including an upwardly/outwardly-extending upper portion;
• a top structure attached to the upper portion of the support structure coaxially therewith and extending outwardly beyond the support structure, the top structure having a bottom surface facing the support structure and having a peripheral portion which is substantially perpendicular to the support-structure axis and surrounds a non-peripheral portion;
• a plurality of LED emitters positioned on the peripheral portion in an annular configuration for emitting light in downward direction substantially outside of the horizontal cross-dimension of the support structure and having no more than minimal light onto the support structure which upper portion being formed by at least one upwardly/outwardly-extending arm positioned with its minimal dimensions in a way of the light such that the upper portion of the support structure permits a through passage of light directed across the greatest top-structure horizontal dimension toward the preferential side from LED emitters positioned farthest therefrom;
• and
• at least a subset of the emitters each having associated LED lensing configured for distribution of light from the emitter in off-axial direction with respect to the emitter axis toward a preferential side, thereby to widen an outward and downward illumination angle or to facilitate illumination in a common downward lateral direction.
