Description

  The present invention belongs to the technical field of an attachment device for attaching a lighting fixture to a raceway arranged in a ceiling space of a building such as a warehouse or a factory. More specifically, for example, the present invention relates to an attachment device for attaching a long straight tube fluorescent lamp perpendicular to the longitudinal direction of the raceway.

  Conventionally, lighting fixtures installed in warehouses and the like have been performed by attaching to a raceway disposed on the ceiling surface. In addition, when the raceway is provided along a passage or a road through which a person passes, a long luminaire such as a straight tube fluorescent lamp is also attached so that its longitudinal direction is along the raceway. However, when the width of the passage or the roadway is wide, the brightness may be insufficient when the longitudinal direction of the long luminaire is attached along the raceway. In this case, the raceway may be formed into a polygonal line, or arranged in multiple rows (for example, two rows) in parallel, but the distance of the raceway becomes longer or the raceway is attached to the ceiling surface. Becomes complicated and the installation cost increases.

As a means for solving such a drawback, a method of increasing the brightness by increasing the arrangement density of the straight fluorescent lamps by attaching the longitudinal direction of the long luminaire in the direction orthogonal to the raceway can be considered. The lighting fixture support fitting shown in Patent Document 1 can cope with such a case. This conventional apparatus will be described below with reference to FIGS.
