Abstract RU 2431774 C2

FIELD: physics.

SUBSTANCE: observation system comprises floodlight with material arranged ahead of light emitting system and provided with fringe micro relief to diverge light beam in horizontal plane, said divergence exceeding two times that of source light beam inside light emitting system. Note here that said material does not in fact affect light beam divergence in vertical plane.

EFFECT: increased floodlight range, higher efficiency.
