Abstract
An LED lamp A1 includes an LED unit 1 in the shape of a straight tube with a plurality of LED modules 12 fixed therein, and also includes a pair of bases 2 that receive electric power from outside and are attached to the ends of the LED unit 1 spaced in the longitudinal direction of the LED unit. The LED unit 1 and the bases 2 are rotatable relative to each other about an axis extending in the longitudinal direction. With this arrangement, the direction of light emission can be changed, with the LED lamp attached to a general-use fluorescent lighting fixture.
