PROBLEM TO BE SOLVED: To provide a lighting fixture capable of improving light extraction efficiency.SOLUTION: A lighting fixture includes: a light emitting diode 2; a light guide member 3 for guiding light of the light emitting diode 2; and a fixture body 1 for surrounding the light emitting diode 2 and the light guide member 3 and for being a reflector for reflecting light of the light emitting diode 2 on an inner peripheral surface. The light guide member 3 has an incident surface 31 facing the light emitting diode 2 side and an emission surface 33 facing the opposite side from the light emitting diode 2, and it guides light entered from the incident surface 31 and emits it from the emission surface 33. A space is provided between the inner peripheral surface of the fixture body 1 and an outer peripheral surface of the light guide member 3. Compared to the case where the inner peripheral surface of the fixture body 1 and the outer peripheral surface of the light guide member 3 are in close contact with each other, and the case where the fixture body 1 is omitted, improvement of light extraction efficiency of the light emitting diode 2 becomes possible. |
