<P>PROBLEM TO BE SOLVED: To provide a luminaire capable of improving cooling efficiency. <P>SOLUTION: Since a heat radiation hole 25 is arranged in the vicinity of the most cooling part 24 of a fluorescent lamp 22 in a reflecting plate 23, light efficiency can be improved by cooling the most cooling part 24. Since a heat radiation part 27 is arranged so as to reach a reverse surface of the reflecting plate 23 via the heat radiation hole 25 by contacting with the most cooling part 24 of the fluorescent lamp 22, heat of the most cooling part 24 can be radiated to the reverse side of the reflecting plate 23 via the heat radiation part 27, and the light efficiency can be further improved by cooling the most cooling part 24. <P>COPYRIGHT: (C)2010,JPO&INPIT |
