Abstract
An LED lighting device includes a plurality of LED chips and a pair of side mounting faces. The distance between the side mounting faces becomes smaller from the base side toward the extremity side in the x direction. The side mounting faces face mutually opposite sides in the y direction. Also, the distance between the side mounting faces becomes shorter from the back side toward the front side in the z direction that is perpendicular to both the x direction and the y direction. The plurality of LED chips include LED chips mounted on the pair of side mounting faces. The LED lighting device illuminates an illumination target with a uniform illuminance distribution.
