Through adopting above-mentioned technical scheme, when the light colour of stage lamp need be changed, utilize drive assembly to order about the lamp source support and rotate, a plurality of light units follow the synchronous rotation of lamp source support, because of the lamp shade is made by transparent material, consequently, the light that every light unit sent all can see through the lamp shade. When the light unit of required colour rotates to just after the light pipe, just the light that the light unit of light pipe sent sees through the lamp shade and jets out through the light pipe to accomplish the regulation of stage lighting colour, make the stage lighting possess the ability of fast switch over light colour, be favorable to improving the light effect of stage lighting. Meanwhile, the support frame is rotatably connected to the base, and the lamp body is rotatably connected to the support frame, so that the lamp body can rotate in space, and the irradiation direction of stage lighting can be adjusted at any time.

Preferably, the lamp shade is hollow cylinder and sets up, be provided with in the casing and be no less than two sets of clearance subassemblies that are used for clearing up the lamp shade, the clearance subassembly includes the brush, the brush is provided with the lateral wall butt of one side of brush hair and lamp shade, the length of brush is not less than the height of lamp shade.

Through adopting above-mentioned technical scheme, the light pipe communicates exterior space and casing inside with the light pipe for the dust gets into inside the casing easily, therefore, through setting up multiunit deashing subassembly, order about the lamp source support when driving assembly rotates in order to drive a plurality of lighting unit, the lamp shade also follows the relative brush rotation of lamp source support, the dust that the brush will depend on the lamp shade on the lateral wall sweeps down, so that the lateral wall of lamp shade keeps clean and tidy, the light brightness of lighting unit has been improved, thereby be favorable to improving the light effect of stage lamp. Meanwhile, the dust on the lampshade is removed, and the heat dissipation of the light unit is facilitated.

Preferably, two groups of the cleaning assemblies are symmetrically distributed on two sides of the light guide pipe and are arranged adjacent to the light guide pipe.

Through adopting above-mentioned technical scheme, because of the light pipe intercommunication is external for just being infected with the dust to the lamp shade of light pipe department most, consequently, through with two sets of deashing subassembly symmetric distribution in the both sides of light pipe and adjacent light pipe setting, no matter the stage lamp is the light of a colour that the transform closes on, still the light of other colours, the lamp shade after the rotation all can be scrubbed by the brush, thereby plays better deashing effect.

Preferably, the connection pipes are communicated between the shells of the adjacent light units, a plurality of groups of ash removal assemblies for removing ash are arranged in the shell, one group of ash removal assemblies corresponds to one connection pipe, each ash removal assembly comprises an ash removal fan and an air guide pipe, one end of each air guide pipe is communicated with the connection pipe, the other end of each air guide pipe penetrates through the side wall of the lampshade, the ash removal fans are arranged on the outer side wall of the lampshade, a gap for the ash removal fan to penetrate through is reserved between one side of each brush provided with bristles and the outer side wall of the lampshade, the air outlet ends of the air guide pipes are covered by the air inlets of the ash removal fans, and the air outlet direction of the ash removal fans is parallel to the tangential direction of the outer side wall of the lampshade.
