<P>PROBLEM TO BE SOLVED: To provide a lighting fixture capable of attaining energy saving by improving reflection efficiency. <P>SOLUTION: Light from an LED emission part 30 installed at a prescribed position of a case 20 is reflected to a prescribed direction by a reflecting plate 40 having a reflecting surface 41 of a curved body, and illumination light is emitted from an emitting surface 24 of the case 20. In this case, since the LED emission part 30 is installed so that the angle θ made by a main optical axis LX of the LED emission part 30 installed in the vicinity of the bottom of the reflecting plate 40 and a center axis AX going toward a larger-diameter opening part 401 of the curved body may be 90 degrees or less, the effective reflection surface R2 to reflect light irradiated in the reflecting plate 40 becomes large and light can be irradiated efficiently to a target direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
