Patent ID: 8545057

Claim:
An LED lighting device comprising: a plurality of LED chips; and a pair of first side mounting faces configured such that a distance between the first side mounting faces becomes shorter from a base side toward an extremity side in a first direction, that the first side mounting faces face mutually opposite sides in a second direction that is perpendicular to the first direction, and that the distance between the first side mounting faces becomes shorter from a back side toward a front side in a third direction that is perpendicular to both the first and second directions, wherein the plurality of LED chips include LED chips belonging to a pair of first side lighting groups mounted on the pair of first side mounting faces, the LED lighting device further comprising a pair of second side mounting faces configured such that a distance between the second side mounting faces becomes shorter from the base side toward the extremity side in the first direction, that the second side mounting faces face mutually opposite sides in the second direction, and that the distance between the second side mounting faces becomes shorter from the back side toward the front side in the third direction, the pair of second side mounting faces being positioned on the base side in the first direction relative to the pair of first side mounting faces, and a distance between extremities of the pair of second side mounting faces being shorter than a distance between bases of the pair of first side mounting faces, wherein the plurality of LED chips include LED chips belonging to a pair of second side lighting groups mounted on the pair of second side mounting faces.
