Abstract: A rotating light-emitting structure for a shower head comprises a housing provided for accommodation of a coverture and a light-emitting device. The coverture integrally encloses the light-emitting device. The coverture and the light-emitting device are coaxially pivoted in the housing. The liquid flows in the housing and sprays from the housing to impact the coverture, so as to make the coverture and the light-emitting device rotate coaxially. The light-emitting device rotates to generate electricity for illumination. By such arrangements, when the power is cut off, the rotating light-emitting structure for a shower can emit light for illumination without using batteries or other power sources.
