Abstract

[Problem] To propose a lighting fixture that can be attached to a mounting surface and that can suppress the increase in size of the lighting fixture compared to conventional fixtures. [Solution] The lighting fixture comprises an arm having a base that is attached to the mounting part and a mounting part that extends from the base in a first direction, a light source holder that holds a light source, and a bolt that is screwed into the light source holder and attaches the light source holder to the arm. The mounting part is formed to have a bolt insertion part into which the bolt is inserted, which penetrates the mounting part and extends in a second direction that is inclined with respect to the first direction. The light source holder is movable in the second direction with the bolt inserted into the bolt insertion part, and is rotatable about the bolt as the center of rotation.

Description

This disclosure relates to lighting fixtures installed on ceilings, etc. Conventionally, lighting fixtures are known that are placed in high places such as ceilings (see, for example, Patent Document 1). Such lighting fixtures are attached to a mounting surface such as an exposed box. Furthermore, such lighting fixtures comprise a mounting member attached to the mounting surface and a light source holder attached to the mounting member to hold the light source. In addition, such lighting fixtures have a mounting hole, which is a through-hole, formed in the mounting member attached to the mounting surface. The lighting fixture is then attached to the mounting surface by screwing a bolt inserted into the mounting hole into a female thread formed in the mounting surface.
