Abstract
A lamp housing for a projector is for accommodating at least a lamp, and a heat-dissipating fan disposed at one side of the lamp housing. The lamp housing includes a housing body, and a baffle plate. In this case, the housing body has a first opening, and the wind blown by the heat-dissipating fan flows from the first opening into the housing body. The baffle plate is disposed between the housing body and the lamp. The baffle plate and the direction of the wind blown by the heat-dissipating fan form an included angle.
