PROBLEM TO BE SOLVED: To provide an LED lighting fixture capable of preventing intrusion of foreign objects such as insects, dust and the like.SOLUTION: An upper LED light emitting part 30 for emitting light by power supply from an attachment adaptor 22 accommodated in a fixture body 20 irradiates an incident end surface 521 of an upper light guide plate 50 with light. Furthermore, an LED lighting fixture includes: a horizontal part 25 and an inclined surface 512 of an upper cover 51 supported by the fixture body 20 and for holding the upper light guide plate 50 in a thickness direction; and an elastic member 54 provided between the upper light guide plate 50 and the inclined surface 512 so as to face the upper LED light emitting part 30 being side by side with the incident end surface 521. Therefore, even when the upper light guide plate 50 is deformed by the heat from an LED chip 322 and a gap occurs, the elastic member 54 prevents a gap, so that intrusion of foreign objects such as insects, dust and the like can be prevented. Also, generation of a squeaking noise and the like caused by occurrence of backlash due to deterioration over time and self-weight can be prevented. |
