PURPOSE:To enable to turn on a lamp stably and to discharge gases favorably, by a method wherein light-irradiating apparatuses each of which consists of a reflector provided at an opening of a lower surface to be forcibly cooled by a fluid and an ultraviolet lamp placed oppositely to the reflector are placed so as to form gas passages communicating to an exhaust port. CONSTITUTION:Three light-irradiating apparatus 4 each of which consists of the reflector 5 provided with a passage 9 for a cooling fluid and a metal halide lamp 6 placed oppositely to the reflector 5 are apacedly placed in a main body 1 of the device so as to form the gas passage 12 communicating to the exhaust port 3. The main body 1 has a lower surface provided with the opening 2 faced to a conveyor 13 for printed matter or the like 14, and is provided with an exhaust fan at an upper surface. By operating the exhaust fan, the outside air is introduced into the main body 1 through the opening 2, passed through the passage 12 and is discharged through the exhaust port 3. |
