PROBLEM TO BE SOLVED: To select various functions of multicolor property and luminous intensity adjustable property that an LED light source has, from outside with an easy and inexpensive mechanism.SOLUTION: The function of a switch included in a spherical body or the like can be selected by operating an operation rod projecting to the outside of the spherical body or the like from the inside of the spherical body or the like. Also, a plurality of switches are included in the spherical body or the like, two directional operability is applied to the operation rod projecting to the outside of the spherical body or the like from the inside of the spherical body or the like, and a switch can be selected with operation in one direction and the function of a switch can be selected with operation in the other direction. Further, by applying to a bulb-shaped LED lamp having a mouthpiece, an LED lamp according to this invention can be widely used as a light source such as a lantern or a paper-covered lamp. |
