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.

One purpose is to smoothly raise and lower a telescopic post used in a floodlight.

A floodlight according to the present invention includes: a telescopic post 2 that has a plurality of posts 21 to 25 whose outer diameters are made gradually smaller, into which the posts 21 to 25 can be loosely fitted, and that can be extended and contracted in an up-down direction; a lighting unit 3 attached to the post 25 located on the innermost side; a raising and lowering unit 26 that extends and contracts, in the up-down direction, the posts 21 to 25 in conjunction with each other; a base 4 that the post 21 located on the outermost side is fixed to; and dampers 27a, 27b that connect a side surface of the post 21 located on the outermost side and a side surface of the post 22 located on the second outermost side.
