Abstract

PROBLEM TO BE SOLVED: To improve working efficiency by bolting a plurality of bolting places of a fluorescent lamp apparatus with an end of an anchor bolt corresponding to it, forming potbellied holes for passing the end of the anchor bolt, and determining the longitudinal direction of each potbellied hole orthogonally to the longitudinal direction of the fluorescent lamp apparatus. SOLUTION: The longitudinal direction of each potbellied hole 1 is determined orthogonally to the longitudinal direction of a lighting system body 2. When a lighting system is installed like a line, the lighting system body 2 is shifted orthogonally to the longitudinal direction and therefore a work is allowed anywhere of a line. Even when the longitudinal direction of the lighting system is sandwiched between right and left walls to provide no margin, the same work is allowed, and even when the line bends and a step occurs on the line, their modification can be easy. Even when the directions of the potbellied holes 1 are mutually inversed, the lighting system body 2 can be rotated to be set, the same effect can be provided. The same effect can be provided also when installation is performed using an anchor bolt and a nut.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long luminaire for line lighting, and more particularly to a direction of a screw hole for a screw hole.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, the longitudinal direction of a screw hole 1 is parallel to the longitudinal direction of a lighting fixture. 2 is a lighting fixture body.

[0003]

The description will be supplemented with reference to FIG. When mounting the lighting fixture on the ceiling, insert the screw 4 partway into the ceiling surface 3 in advance (FIG. 7).
(1)) The screw 4 is passed through the large diameter hole 5 of the harmony hole 1 of the luminaire body 2 (FIG. 7 (2)), and the luminaire body 2 is shifted in the longitudinal direction of the harmony hole to form the harmony hole. The screw 4 is positioned in the small hole 6 having a diameter of 1 (FIG. 7 (3)), and in this state, the screw 4 is securely tightened to fix the main body 2 of the lighting fixture to the ceiling surface 3 (FIG. 7 ( 4)) Then, a reflector and a fluorescent lamp (not shown) are attached. However, in order to install the luminaires in a line, the above-described prior art requires the individual luminaires to be appropriately shifted in the longitudinal direction, so that the operation is to install the luminaires from the end of the line, resulting in poor work efficiency. An object of the present invention is to solve the above problem.

[0004]

The above object is achieved by defining the longitudinal direction of the daruma hole so as to be orthogonal to the longitudinal direction of the luminaire. According to the above, when the lighting equipment is installed in a line, the lighting equipment main body is shifted in a direction perpendicular to the longitudinal direction, so that the work can be performed anywhere on the line, so that the working efficiency can be improved.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the longitudinal direction of the Daruma hole 1 is determined to be orthogonal to the longitudinal direction of the lighting fixture body 2. Thus, when the lighting fixture 7 is installed in a line, the lighting fixture main body 2 is shifted in a direction perpendicular to the longitudinal direction, so that work can be performed anywhere on the line. According to the present embodiment,
The same operation can be performed even when the longitudinal direction of the luminaire 7 is sandwiched between the left and right walls 8 as shown in FIG. 2 and there is no room, and even if the line is bent as shown in FIG. If it does, it can be easily corrected. Another embodiment of FIG. 5 will be described. In the present embodiment, the direction of the daruma hole 1 is reversed, and the luminaire main body 2 can be set by rotating, and the effect is the same as described above. It goes without saying that the same effect can be obtained in the above-mentioned embodiment also in the case of installation using anchor bolts and nuts.

[0006]

According to the present invention, the longitudinal direction of the daruma hole is made perpendicular to the longitudinal direction of the luminaire, so that when the luminaire is installed in a line, the luminaire main body is perpendicular to the longitudinal direction. Since it is shifted in the direction, work can be performed anywhere on the line, which has the effect of improving work efficiency.
