Abstract
A light-emitting assembly with a micro hydraulic power generator includes a power generation module and a light-emitting module. The power generation module includes a housing, a coil module and an impeller. An accommodating space inside the housing is divided by a transverse baffle therein into two cavities, respectively a coil cavity and an impeller cavity. A side wall of the impeller cavity is provided with at least one water inlet. At least one internally recessed portion is provided at a connection portion between the transverse baffle and an outer wall of the coil cavity, and the transverse baffle defines a water outlet at a portion positionally corresponding to the internally recessed portion. The coil module is arranged in the coil cavity in a sealed manner by a colloidal material. The impeller is placed in the impeller cavity, the impeller can be rotated by an external force.
