PROBLEM TO BE SOLVED: To provide an LED lighting fixture capable of maintaining a relative position of a light emitting part and an incident end surface at a normal position for a long time by supporting a light guide plate without damaging it, and capable of reducing loss of light.SOLUTION: An LED lighting fixture 10 has: an LED light emitting part 30 accommodated in a fixture body 20; and a light guide plate 50 supported by the fixture body 20 and arranged so that an incident end surface 53 of the LED light emitting part 30 faces it. The LED light emitting part 30 has: a substrate 33 on which an LED chip 32 is mounted; a holder 31 for holding the substrate 33; and an eaves part 34 protruding from the holder 31. The eaves part 34 has a covering surface 343 which is parallel with respect to a surface orthogonal to the incident end surface 53 of the light guide plate 50, and which continues along the longitudinal direction of the substrate 33. In the eaves part 34, a tip 346 extends from the incident end surface 53 to an arbitrary position on the opposite side from the incident end surface 53. Thereby, the covering surface 343 of the eaves part 34 comes into contact with the light guide plate 50, so that a relative position of the light emitting part 30 and the incident end surface 53 can be maintained at a normal position for a long time by supporting the light guide plate 50 without damaging it. As a result, loss of light can be reduced. |
