PROBLEM TO BE SOLVED: To provide a power generation lamp that can generate power by replacing an existing fluorescent lamp or an LED lamp.SOLUTION: In a straight-tube type or a circular-tube type fluorescent lamp or LED lamp, at least a back part (11A) of a lamp tube (11) is formed in a double structure having a storage space, and the storage space has an arc length (W) of 1/5 or more to 1/2 or less of a cross-section outer peripheral length of the lamp tube in a lamp tube peripheral direction. A solar panel (14) is built-in in the storage space, and electromotive force of the solar panel (14) is taken out by current-carrying wires (15). In case of the LED lamp, a solar panel having a cross-section arc belt shape can be pasted on the inside of the back part of the lamp tube. |
