There is a heat elimination hole on the corresponding position of an intumescent sheet for fire preventing, and/or between the edge of the intumescent sheet and the edge of the heat elimination opening. The heat elimination opening and the intumescent sheet for fire preventing on the hood are so arranged that the light fitting may be heat eliminated normally in the general case, and in the event of fire the heat elimination opening is enclosed of itself due to quickly expanding of the intumescent sheet for fire preventing. Therefore, the hood may prevent fire from propagating from the interior to the exterior.
