| description | PROBLEM TO BE SOLVED: To provide an LED lighting device for attaining which lighting with satisfactory power efficiency for securing required illuminance according to a lighting object while suppressing color unevenness.SOLUTION: This LED lighting device includes: a light source which radiates at least mixed color light between light with first wavelength and light with second wavelength; and a uniform optical body which promotes uniformization of the radiated mixed color light. Between them, the uniform optical body has: a light distribution angle control lens part which controls a light distribution angle of the mixed color light; and a microlens arrangement part which includes a plurality of arranged microlenses, receives and distributes the mixed color whose light distribution angle is controlled. A curvature radius R, a pitch P between the adjacent microlenses, or both of the curvature radius R and the pitch P are different between a direction of one axis and a direction of an axis perpendicular to the axis for the curvature radius R, and between directions of each of the axes connecting lens apexes for the pitch P, and distribution of the mixed color light is controlled for every direction. |
