摘要

PROBLEM TO BE SOLVED: To provide a lighting fixture capable of suppressing a potential difference between a main light source part and an all-night lamp light source part small.SOLUTION: A lighting fixture 10 includes: a fixture body 14 supported by a building material 11; a lead-in hole 15 provided at the fixture body 14; and a circuit board 16 supported by the fixture body 14. The circuit board 16 includes: a main light source part 36 which is formed by a number of main light source LED chips 37 being connected in series on a surface 16B on the opposite side from the fixture body 14; and an all-night lamp light source part 41 having an all-night lamp LED chip 42. Furthermore, a cathode 45 side end part of the main light source part 36 and a side end part of a cathode 51 side of the all-night lamp light source part 41 are connected to a common ground.SELECTED DRAWING: Figure 5
