Claim:
1. A fluid cooled lamp comprising: a heat conductive pipe having a plurality of heat conductive surfaces arranged annularly and a hollow channel arranged among the plurality of heat conductive surfaces; a plurality of illumination modules respectively arranged at each heat conductive surface and thereby transfer heat to each heat conductive surface; a junction assembly comprising an inlet joint and an outlet joint, and the inlet joint and the outlet joint being respectively communicated to both ends of the hollow channel of the heat conductive pipe; a flow guiding inner tube communicated with the inlet joint and located in the hollow channel of the heat conductive pipe, a plurality of spray holes communicated with the outlet joint being defined on the flow guiding inner tube, each spray hole being arranged toward an inner wall of the heat conductive pipe; and a fluid flowing from the inlet joint and sequentially flowing toward the flow guiding inner tube, each spray hole, the heat conductive pipe, and the outlet joint; the fluid being sprayed from each spray hole and impacting the inner wall of the heat conductive pipe, and thereby removing heat from the heat conductive pipe.
