    摘要: A lamp house prevents danger when a lamp bulb, acting as a light source in a housing, breaks. The lamp house includes, at inlet and outlet vents for cooling the lamp bulb, movable plates which are movable only toward the inside of the housing of the lamp house. Springs for closing the movable plates are provided and a sensor for detecting opening and closing states of one of the movable plates is disposed on the side of the inlet vent.
