Provided is a power generating lamp, wherein electromotive force with sufficient magnitude is enabled to be generated by effectively utilizing electric energy of an illumination. A solar panel (11), which is for generating electromotive force by receiving light from the back face of a linear-formed or circular-formed lamp tube (14), is configured to be belt shaped with an arc-formed cross section, wherein the belt has a length within a range of not more than the overall length in the longitudinal direction or the overall length in the circumferential direction of the lamp tube, and not less than the overall length in the longitudinal direction or the overall length in the circumferential direction of the low-temperature zone of the lamp tube, and has a lateral width within a range of not less than 1/4 and not more than 1/2 of the outer circumferential length of the cross section of the lamp tube. A transparent heat-resistant layer (12) is laminated on a light receiving face of the solar panel, and the transparent heat-resistant layer is pasted on a back face of the lamp tube, or arranged backwards from the lamp tube such that the gap between the light receiving face thereof and the back face of the lamp tube will be 10 mm or less. The electromotive force of the solar panel is taken out via current flowing wires (11A), to constitute a power generating lamp (10). |
