LIGHTING EQUIPMENT AND PROJECTION DISPLAY DEVICE

摘要

Lighting equipment using lens arrays and capable of eliminating such a trouble that the peripheral parts of an illuminating area become extremely dark, comprising a light generating means (11), a condensing means (12) for condensing outgoing light from the light generation means (11), a first lens array (13) formed by arranging a plurality of first lenses for letting in outgoing light flux from the condensing means (12), a lattice-shaped aperture diaphragm (14) disposed at a position in correspondence with the lens boundary lines of the first lens array (13), and a second lens array (15) formed by arranging a plurality of second lenses for letting in outgoing light from the lattice-shaped aperture diaphragm (14).
