PURPOSE: A heat processing apparatus of a ceiling lamp is provided to reduce a cooling load and a heating demand by opening and closing a vent hole of a reflector through an opening/closing device. CONSTITUTION: A reflector(30) is buried on a ceiling(10). An electric lamp(40) is mounted on a socket of the reflector. A vent hole is formed on the reflector. The vent hole discharges a heat of the electric lamp to the upper side of the ceiling. An exhaust fan(20) discharges the heat of the electric lamp from the upper side of the ceiling to the outside. An opening/closing device opens and closes the vent hole. The opening/closing device includes a slide plate(50). An exhaust hole is formed on the slide plate. |
