<P>PROBLEM TO BE SOLVED: To provide a lamp apparatus in which a cooling air flowing in a lamp house is guided in a low resistance into a different direction from an orientation direction at a time of flowing in and a whole of a lamp can be efficiently cooled down. <P>SOLUTION: In the lamp apparatus in which a lamp 2 is accommodated in a lamp house 1 with a flowing-in port 6 where a cooling air for cooling down the lamp 2 is provided, there is provided an air guiding plate 20 provided with rectifying surface 20a which is arranged near the flowing-in port 6 and extends along an orientation direction of the cooling air which flows in from the flowing-in port 6 and an air guiding surface 20b which contacts with one side of the rectifying surface 20a and moreover which inclines against the rectifying surface 20a, and the air guiding surface 20b inclines against the rectifying surface 20a so that it comes gradually near a center of the lamp 2. <P>COPYRIGHT: (C)2009,JPO&INPIT |
