Description

  The present invention relates to a lighting fixture and a lighting system, and more particularly to a lighting fixture and a lighting system that can be suitably used in a store.

  Many lighting fixtures equipped with lamps such as fluorescent lamps are arranged at exhibition halls, department stores, and mass retailers to illuminate displayed products. At these stores, the layout of merchandise displays and the merchandise displayed are frequently changed, and it is necessary to change the arrangement of the lighting fixtures in order to adjust the lighting direction of the merchandise every time these changes are made. Such a change in the arrangement of the luminaires involves a change in other members such as a power source and a cord, which is a very troublesome work. For this reason, it is desired that only the illumination direction can be changed without changing the location of the luminaire.

Patent Document 1 describes a structure for changing the direction of a reflective hood of an instrument body to which a fluorescent lamp is attached in order to change the illumination direction. In this structure, elongated holes are formed at both ends in the longitudinal direction of the reflective hood, and screws are passed through the elongated holes to attach the reflective hood to the instrument body. Then, the screws at both ends are loosened, the reflecting hood is slid and tilted, and then the screws are tightened to fix the reflecting hood in a tilted state. Thereby, since the reflection direction of light can be changed, the illumination direction can be changed.
