Provided is a power generating lamp capable of effectively use electrical energy of lighting to generate high electromotive force. A solar panel (11) which receives light emitted from a rear surface of a lamp tube (14) with a linear or annular shape and generates electromotive force is formed in an arc shape in a cross-sectional view and has a length that is equal to or less than the total length of the lamp tube in the longitudinal direction or the total length thereof in the circumferential direction and is equal to or greater than the total length of a low-temperature region of the lamp tube in the longitudinal direction or the total length thereof in the circumferential direction and a width that is equal to or greater than one-fourth of the length of the outer circumference of the cross-section of the lamp tube and equal to or less than half the length of the outer circumference. A transparent heat-resistant layer (12) is formed on a light receiving surface of the solar panel and is attached to the rear surface of the lamp tube or is arranged on the rear side of the lamp tube such that a distance between the light receiving surface and the rear surface of the lamp tube is equal to or less than 10 mm. An electric wire (11A) extracts the electromotive force of the solar panel. In this way, a power generating lamp (10) is formed. |
