<P>PROBLEM TO BE SOLVED: To provide a lighting fixture having a reflecting plate structure capable of efficiently extracting light of an LED in a structure wherein a reflecting plate is divided into two parts. <P>SOLUTION: An LED 32 (a light source) for emitting light is mounted on one surface as a mounting surface 30a of an LED mounting board 30. A lower reflecting plate 11 (a first reflection section) has a first reflecting surface 11aa as a reflecting surface rising up to an upper side which is a normal direction X of the mounting surface 30a by a designated distance H only from the vicinity of the LED 32 while a circumference of the LED 32 is surrounded. An upper reflecting plate 12 (the second reflection section) has a second reflecting surface 12aa, which is arranged further toward an upper side than the first reflecting surface 11aa of the lower reflecting surface 11 (the first reflection section) and is a reflecting surface for forming a curved surface approximately continued to the first reflecting surface 11aa by nearly smoothly jointing with the first reflecting surface 11aa at a position of the distance H. <P>COPYRIGHT: (C)2012,JPO&INPIT |
