Abstract
A power generating lamp capable of effectively use electrical energy of lighting to generate high electromotive force comprising a linear or annular lamp tube that is supplied with power and emits light and one or a plurality of solar panels that have an arc shape in a cross-sectional view or a linear shape a cross-sectional view.
Claims15
A power generating lamp comprising:
- a linear or annular lamp tube that is supplied with power and emits light;
- one or a plurality of solar panels that have an arc shape in a cross-sectional view, have a length that is equal to or less than the total length of the lamp tube in a longitudinal direction or the total length thereof in a 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-fifth of the length of the outer circumference of a cross-section of the lamp tube and equal to or less than half the length of the outer circumference, receive light emitted from a rear surface of the lamp tube, and generate electromotive force;
- a transparent heat-resistant layer that 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;
- and
- an electric wire that extracts the electromotive force of the solar panel.
