Description

  The present invention relates to an elevating lighting fixture, and more particularly to the structure of a guide portion of an auto lifter lighting fixture.

  The auto lifter that automatically raises and lowers the luminaire allows maintenance and inspection of the luminaire mounted on a high ceiling to be easily performed by operating the switch on the ground. It has become widely used on high ceilings such as in gymnasiums and gymnasiums.

  In such a lifting type lighting fixture, the lamp is lifted and lowered by suspending the lamp with a plurality of wires from a fixed frame attached to the ceiling, and unwinding and winding the wire with a lifter provided on the fixed frame. And normally, a lamp is accommodated in a fixed frame by hold | maintaining a wire in a winding state.

  By the way, in such a raising / lowering type lighting fixture, since the wire is comprised by the strand wire, when raising / lowering a lamp, a twist arises in a wire and a lamp is vibrated along a horizontal surface. In this case, since the lamp only vibrates in a wide space when the lamp is lowered, there is no particular problem. However, when the lamp is raised and stored in the fixed frame, a positional shift occurs. Sometimes.

  For example, when the light source provided in the lamp is composed of a plurality of lamps arranged in a row or a straight fluorescent lamp, the lamp shade shape is often formed in a square shape such as a rectangle. . In addition to this, the fixed frame for storing the lamp is also formed in a square shape so as to match the shape. Therefore, when the lamp having such a shape is raised and stored in the fixed frame, when the lamp vibrates along the horizontal plane, each corner of the lamp abuts on the bottom of each side of the fixed frame. May not be able to wind the lamp further, making it impossible to store the lamp in the fixed frame, or excessive load may be applied to the lifter, resulting in failure.

  Therefore, a vibration suppression mechanism is provided that has a spring member that applies a turning force in the direction opposite to the vibration direction of the shade by pressing the ridge line of the rising lamp, and the vibration of the lamp is suppressed by the biasing force of the vibration suppression mechanism. (For example, see Patent Document 1 below), or a torsion detection switch for detecting the vibration of the lamp is provided. When the lamp vibrates more than a predetermined amount, the torsion detection switch is turned on and the wire is wound by the lifter. The operation is stopped, and when the vibration of the lamp becomes a predetermined amount or less due to this stop, the twist detection switch is turned off and the wire winding operation by the lifter is resumed (for example, see Patent Document 2 below) Etc. have been proposed.

Further, the applicant of the present invention temporarily stops the winding operation of the wire by the lifter until the vibration of the lamp substantially stops immediately before a part of the lamp is stored in the fixed frame. An elevating type lighting apparatus using a controller that performs control to restart the lifter after a lapse of time has been proposed (Patent Document 3).
Further, in this apparatus, a locking piece protrudes from one side of the fixed frame and the lamp, and a guide locking groove that contacts and locks the locking piece is formed on the other side.
